Gonzalez, Oscar, and David P. MacKinnon. "A Bifactor Approach to Model Multifaceted Constructs in Statistical Mediation Analysis." Educational and Psychological Measurement 78, no. 1 (October 14, 2016): 5–31. http://dx.doi.org/10.1177/0013164416673689.
Full textAbstract:
Statistical mediation analysis allows researchers to identify the most important mediating constructs in the causal process studied. Identifying specific mediators is especially relevant when the hypothesized mediating construct consists of multiple related facets. The general definition of the construct and its facets might relate differently to an outcome. However, current methods do not allow researchers to study the relationships between general and specific aspects of a construct to an outcome simultaneously. This study proposes a bifactor measurement model for the mediating construct as a way to parse variance and represent the general aspect and specific facets of a construct simultaneously. Monte Carlo simulation results are presented to help determine the properties of mediated effect estimation when the mediator has a bifactor structure and a specific facet of a construct is the true mediator. This study also investigates the conditions when researchers can detect the mediated effect when the multidimensionality of the mediator is ignored and treated as unidimensional. Simulation results indicated that the mediation model with a bifactor mediator measurement model had unbiased and adequate power to detect the mediated effect with a sample size greater than 500 and medium a- and b-paths. Also, results indicate that parameter bias and detection of the mediated effect in both the data-generating model and the misspecified model varies as a function of the amount of facet variance represented in the mediation model. This study contributes to the largely unexplored area of measurement issues in statistical mediation analysis.

Purpose Success and failure in mediation are widely understood to determine whether a state will receive positive or negative reputation outcomes from undertaking a mediation role in an international conflict. Research from mediation in domestic settings contradicts this view, finding that peer mediators in school and community settings received positive mediator outcomes from undertaking their role, even when they failed to facilitate an agreement between disputants. This paper aims to test this assumption and argues that mediation success and failure are only weakly correlated with observable reputation outcomes for mediating states and proposes an alternative explanatory framework. Design/methodology/approach The hypothesis was inductively generated through a comparative analysis of single-state mediation attempts selected from the Uppsala Conflict Database Project MILC data set. The cases selected were South Africa’s mediation attempts in Côte d’Ivoire from 2004 to 2005 and Comoros from 2003 to 2004, and Mexico’s mediation attempts in Colombia (National Liberation Army) in 2004 and Guatemala (Guatemalan National Revolutionary Unity) between 1994 and 1996. To contextualise the findings and develop the explanatory framework, South African mediation attempts in Burundi and the DRC are discussed in the closing sections of the paper. Findings This paper finds that mediation success and failure are only weakly correlated with mediator outcomes. Mediator outcomes are explained by the activity level of the mediating state in providing mediation services; the positive intention of the mediator to assist in resolving the conflict; the scale of the conflict mediated; the severity of spill over effects from the conflict in question; the regional importance of the conflict; the proximity of the government which a mediating state looks to develop relations with to the conflict; the importance of the mediation attempt within the peace process; the level of contestation of the mediation attempt, meaning the extent to which mediation attempts are themselves sites of regional or global international power politics; and the success or failure of the mediation attempt. Originality/value An explanatory framework for state mediator outcomes in which the outcome of a mediation attempt for the third-party state is not determined solely, or even primarily, by mediation success or failure bridges mediation research applying to international and domestic issue areas and provides additional information for policy makers regarding the costs and benefits of committing their state to processes of mediation in conflicts with low probabilities of resolution. This is particularly important for state policy makers, given that mediation is successful on average in only one out of every three attempts.

Full textAbstract:
Mediated learning is an interpersonal experience in which the mediator’s role is to develop in the mediatee functions essential for learning. The mediator focuses on the mediatee while identifying, analyzing, formulating, and solving problems related to everyday life and formal education frameworks. This study was focused upon the mediators, their experience in mediated learning, and the development of mediational abilities and cognitive functions as a result of social goals.Mediation was carried out in pairs and in a group format. The group was composed of low-functioning young adults suffering from severe learning problems. They acted in pairs, using a peer mediating activity, and also worked in the group to replicate their actions as well as to study the theory of mediated learning, its procedure, and its activities. The tasks were taken from Feuerstein’s cognitive intervention program, Instrumental Enrichment.Such a framework allowed me to identify and capture different aspects of students’ cognitive functioning as well as their inter- and intrapersonal mediation. Each student had to play different roles, sometimes acting as mediator to another member of the group, and thus focusing on his/her difficulties and needs, and at other times being a mediatee and receiving mediation from another group member. In addition, each student participated in the whole group activity reflecting upon, analyzing, and evaluating his/her own and his/her peer’s actions as well as those of others in the group. All this promoted strong experience in mediated learning, in different distances and modalities. Three different instruments were developed as a means of data collection and analysis: the mediation circular profile, the structural hierarchy of deficient cognitive functions map, and the process analysis flow chart.The study unfolded as a microdevelopmental process with students starting at a very low level of cognitive functioning and mediational ability and gradually progressing toward quite sophisticated methods of interaction, mediation, and problem solving. In the course of such microevolution, each group member developed his/her own position and role within the group and in the group activities.The findings support the theory of Structural Cognitive Modifiability while showing that even low-functioning people, who usually play the role of mediatee, can be mediators. By mediating to other people, they improve their own cognitive functioning, abstract level of thinking, and social and communication skills.

Full textAbstract:
Purpose: This study aims to examine the role of good corporate governance (board of directors and board of commissioners) in mediating the bond between intellectual capital and financial performance.
Design/methodology/approach: This study obtains data from 264 manufacturing companies listed on the Indonesia Stock Exchange in the 2015 – 2020 period. This study employs the Warp PLS 7.0 program. The tested research model is the multiple mediator model, with more than one mediating variables, so it requires multiple mediation analysis.
Findings: The results reveal that intellectual capital has no effect on financial performance. Intellectual capital has a significant negative effect on the board of directors and board of commissioners, while the board of directors and board of commissioners have a significant positive effect on financial performance.
Practical implications: Intellectual capital affects financial performance through the board of directors and board of commissioners’ as the mediating variables supported by the category of competitive mediation (inconsistent mediation). This competitive mediation provides support for the mediating effect hypothesis.

This paper explores mediator interactions from within the mediation process. It is difficult to obtain access to mediations due to issues of confidentiality and litigation privilege, thus restricting direct empirical research. During a yearlong ethnographic study during which the author was a participant-observer of a number of commercial mediations, the nature of mediations was explored from an independent observational perspective – separate from the process yet within the process. In this study, real life patterns of interactions are examined through case study analysis. It offers a reconceptualization of the nature of mediator interventions, one that moves beyond the accepted understanding of third party intervention. It suggests that the mediator has a fugitive identity in mediation, reflecting a traditional neutral third party intervener role, a party role and an adviser role.Dans le présent document, l‟auteure explore les interactions des médiateurs dans le cadre du processus de médiation. Il est difficile d‟obtenir l‟accès aux séances de médiation en raison du secret professionnel et du privilège relatif au litige, et cette difficulté limite la recherche empirique directe. Au cours d‟une étude ethnographique qui s‟est déroulée sur une année et à laquelle l‟auteure a participé comme observatrice d‟un certain nombre de médiations commerciales, la nature des médiations a été explorée d‟un point de vue observationnel indépendant – distinct du processus bien qu‟au sein du processus. Dans la présente étude, des situations réelles d‟interaction sont examinées au moyen de l‟analyse d‟études de cas. L‟auteure offre une reconceptualisation de la nature des interventions du médiateur, qui va au-delà de ce qui est reconnu comme l‟intervention d‟une tierce partie. Le médiateur aurait une identité fugace dans le processus de médiation, cette identité s‟expliquant par un rôle traditionnel de tiers intervenant neutre, un rôle de partie et un rôle de conseiller.

Purpose The purpose of this study is to explore possible factors leading to a successful mediation in Chinese mediation shows. In China, media always play an indispensable role in information dissemination, morality advocacy and policy explanation. Design/methodology/approach This paper employed content analysis of 166 episodes of one representative mediation show, Gold Medal Mediation, and regression technique in data analysis. Findings Results of ordinal regression suggested that “secret talking”, rather than transparency, between disputants had significant influence on successful mediation. Function of mediators is limited in reaching full mediation. The effective factors leading to full mediation include compromise of rights, secret talking, attitude of the observer cohort. It suggests that the role of mediator is limited, rather than being over-exaggerated, in successful mediation. The successful mediation is largely dependent on disputants’ motivations. Additionally, “compromise of rights” by disputants is a key factor in solving disputes. Research limitations/implications Findings of this study revealed the role of Chinese mediation shows in propagating mediation in contemporary Chinese society and supporting upheld morality values. Due to the nature of the chosen mediation show, some disputes take more than one episode to solve. However, this study looks at each episode without considering the integrity of the dispute. That is, if the disputes take two episodes, the coder codes the two episodes as two separate disputes instead of looking at it as one dispute. Originality/value By exploring various aspects of mediations shows, including the role of mediators, disputants and a cohort of observers, this study can both explicitly show predicted factors to successful mediations on the shows, and can implicitly examine the power and perceived justification of mediation in contemporary China via media.

Full textAbstract:
Effective and powerful survival mediation models are currently lacking. To partly fill such knowledge gap, we particularly focus on the mediation analysis that includes multiple DNA methylations acting as exposures, one gene expression as the mediator and one survival time as the outcome. We proposed IUSMMT (intersection-union survival mixture-adjusted mediation test) to effectively examine the existence of mediation effect by fitting an empirical three-component mixture null distribution. With extensive simulation studies, we demonstrated the advantage of IUSMMT over existing methods. We applied IUSMMT to ten TCGA cancers and identified multiple genes that exhibited mediating effects. We further revealed that most of the identified regions, in which genes behaved as active mediators, were cancer type-specific and exhibited a full mediation from DNA methylation CpG sites to the survival risk of various types of cancers. Overall, IUSMMT represents an effective and powerful alternative for survival mediation analysis; our results also provide new insights into the functional role of DNA methylation and gene expression in cancer progression/prognosis and demonstrate potential therapeutic targets for future clinical practice.

Purpose This study aims to more deeply examine the various types of testing mediations and use the comparison test by using test-based mediation Sobel models and Bayesian approach. The purpose of this study are to apply the traditional (using indirect effect) and Sobel test, extend Yuan and MacKinnon (2009) work on Bayesian mediation analysis. Both analysis methods of mediation (Traditional, Sobel Test and Bayesian estimation) should apply in the research of management, by using structural equation modeling (SEM) in a structural model, with one mediation, one exogenous (independent) and one endogenous variable. The meta-analysis approximation has been used to investigate the job satisfaction as a mediation in the relationship between employee competence and performance (endogenous). Design/methodology/approach Data were collected from ten dissertations of students of the Management Doctoral Program at the Brawijaya University from 2009 until 2013; data were analyzed for the mediation variable of job satisfaction (M) in the relationship between employee competence (X) and employee performance (Y) (Muindi and Obonyo, 2015; Olcer, 2015; Sattar et al., 2015; Khan and Ahmed, 2015). A researcher can determine the mediating variable and whether it is complete or partial or if mediation exists in several ways. Findings The results of the above findings using meta-analysis showed that 60% of previous research states that job satisfaction is a partial mediation on relationship competence of the performance, 10% of previous research states that job satisfaction is a full mediation on relationship competence of the performance and 30% stated that job satisfaction is not pemediasi (pemediasi means Mediation variable) on the relationship between competence and performance. This research found that all three approaches provide similar conclusions for ten previous research. Research limitations/implications The findings showed that the Sobel approach and the Bayesian approach provide results that are more sensitive than the traditional approach. Practical implications In my opinion, the rule to investigate the mediation variable should be completed with the conditions (1) q (theta) is not statistically significant, (2) α (alpha) and β (beta) are significant, and (3) q’ (theta) is significant, and increase when M is include as an additional predictor. This condition called partial mediation. Social implications The traditional method is simpler and easy. The method is less sensitive and is not sufficient for investigating the mediating variables. In general, the method results in a mediation variable, but it cannot be used to determine either partial or complete mediation variables. So, investigation by Baron and Kenny Methods (in Hair et al., 2010), the rule or testing called Sobel Test and another approach such as Bayesian to determine the mediation variable is necessary. Originality/value Various methods for detecting mediating/intervening have been widely used in previous research as a method of measurement using indirect effect (Hair et al., 2010), and calculations have been performed using Sobel test (Baron and Kenny, 1986) and Bayesian approach (Enders, 2013). In this study, I wanted to more deeply examine the various types of testing mediations, and use the comparison test by using the test-based mediation Sobel models and Bayesian approach (Baron and Kenny, 1986; Enders, 2013). The statistical application should not be complicated and difficult, it but must rather be simple and easy, so that it is user-friendly. The traditional method is simpler and easier than the other methods, but how sensitive is it? This research is conducted to investigate this problem. The evaluation of mediating mechanisms has become a critical element of behavioral science research (Enders, 2013), especially in the field of management, not only to assess whether (and how) interventions achieve their effects but also, more, broadly, to understand the cause of behavioral change. Methodologists have developed mediation analysis techniques for a broad range of substantive applications. However, methods for estimating mediation mechanisms with various methods have been understudied. The purpose of this study is to apply the traditional (using indirect effect) and Sobel tests and extend Yuan and MacKinnon’s (2009) work on the Bayesian mediation analysis. Both analyses methods of mediation (traditional and Sobel test and Bayesian estimation) should apply in the research of management, by using structural equation modeling (SEM) in a structural model, with one mediation, one exogenous (independent) and one endogenous variable. The meta-analysis approximation has been used to investigate job satisfaction as the mediation in the relationship between employee competence and performance (endogenous). This study uses software R to complete the mediating effect (Enders, 2013). R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers et al. R provides a wide variety of statistical analyses such as SEM and Mediation test. R provides an open source route for participation in that activity. The Bayesian estimation approach provides an R function and a macro that applies the method of mediation analysis.

PurposeThe purpose of this paper is to investigate the mechanism by which uses and gratification (U&G) constructs predict continuance intention to play (ContInt) the augmented reality game Pokémon Go (PG), through multiple serial mediation technique, with enjoyment and flow as mediators. The model also integrates other motivational factors specific to PG, namely, network externality and nostalgia and investigates the process by which they influence ContInt through players’ inherent need-to-collect animated monsters and online community involvement, respectively.Design/methodology/approachThe model was tested using 362 validated responses from an online survey of PG players in Malaysia. Partial least squares structural equation modeling was used to analyse the data. The predictive relevance of the model was tested via partial least squares-Predict.FindingsContInt is influenced through various mechanisms. Enjoyment is the most important mediator, mediating three U&G predictor constructs (achievement, escapism, challenge and social interaction) and the outcome ContInt. Flow did not have any influence on ContInt unless coupled with enjoyment as a serial mediator. Network externality and nostalgia were found to only influence ContInt through mediators, online community involvement and need-to-collect Pokémon Monsters, respectively. Overall, the results show evidence of four indirect-only mediation paths and one complementary partial mediation path.Originality/valueProvides support for an integrated model incorporating psychological, social and gaming motivational factors. While most other studies focus on direct relationships, we focus on indirect relationships through multiple sequential mediation analysis, following the recent modern mediation analysis guidelines. Contrary to previous findings, flow was not an important factor in predicting ContInt for gaming and nostalgia does not link directly to ContInt.

Mediation in Islam is known as Islâh and hakam. When a dispute or dispute occurs, the disputing parties make peace efforts by appointing a judge. In the case of divorce, the function and efforts to reconcile are the obligations of the judge as a mediator which must be carried out based on Supreme Court Regulation no. 01 of 2016 concerning Mediation Procedures in Courts. Therefore, peace efforts are sought through mediation in the Religious Courts so that couples who want to divorce cancel their intentions and reconcile. However, the reality is that the success rate of mediation in divorce cases is still relatively low. This is evidenced by the number of cases that end in the trial process, compared to the success of the Mediation process. The purpose of this study was to analyze the implementation of divorce case mediation based on Perma No. 1 of 2016. As well as analyzing Islamic law on the implementation of mediation in divorce cases at the Gedong Tataan Religious Court and the Pringsewu Religious Court. The method used in this research is descriptive qualitative with theological, juridical normative and sociological approaches, with the object of research being the Gedong Tataan Religious Court and the Pringsewu Religious Court in Lampung. The primary data in this study were obtained from interviews with the Mediator Judge. The secondary data used is the report on the success and failure of the mediation implementation recorded in the final report and the Case Investigation Information System (SIPP). The results obtained from the research that the implementation of mediation at the Gedong Tataan and Pringsewu Religious Courts, based on PERMA No. 1 of 2016, but the implementation of mediation cannot be said to be optimal or not effective, because the success of mediating divorce cases is still relatively low. Mediation or Islah in resolving domestic conflicts actually contains benefits, namely maintaining the objectives of Islamic law (maqasid al-syariah), namely maintaining religion, soul, mind, lineage, and property. Maqashid sharia in mediation is hifd al-nasl (keeping offspring)

Full textAbstract:
Parental support is an important factor affecting young people’s mental well-being, but the school climate also plays an important role. However, few studies have previously examined whether the school climate serves as a mediator for adolescents’ mental health problems. This study aimed to investigate the association between parental support and students’ psychological complaints, while also examining the possible mediating role that a good school climate may have. Data derives from 5783 senior-level students (age 15–16) distributed over 152 school units in Stockholm municipality. Regression linear analysis was used for the analysis and Baron and Kenny’s four-step mediation model has been applied. Sobel’s test was conducted in order to test the significance of the mediation effect. The results show that there is a significant negative association between parental support and students’ psychological complaints, and that school climate has a mediating role in this association. It can be concluded that school climate has a partly mediating role in the association between parental support and students’ psychological complaints. Therefore, it seems important to develop the school climate in order to strengthen this source of support to reduce mental health problems among adolescents.

Purpose This study aims to better understand the socialization process individuals undergo when training to become a conflict mediator. Design/methodology/approach This paper presents an analysis of Michigan’s state-wide training guidelines, training documents and eight semi-structured narrative interviews from participants of two 40-hour mediation trainings. Findings Results are presented with regard to pre-training and post-training beliefs about mediation alongside data gathered regarding mediator tactics, beliefs and potential for transformation. In sum, newly trained mediators often undergo a phase of “unlearning” before returning to a settlement-focused facilitative model of mediation. Practical implications The paper presents implications for facilitative mediator training, training materials and role-play activities. Originality/value Third-party interventions can impact conflicts both positively and negatively. Currently, many states and municipal districts have engaged individuals through mediation training to act as a positive force for conflict resolution. Thus far, very little is understood about the development of individuals through mediation training.

This study aims to explore the concept and urgency of mediator’s good faith in mediating civil law. It is a normative juridical study (doctrinal) with secondary data from primary and secondary legal materials, using bibliography technique. Those materials are analyzed with a qualitative descriptive method. Further, good faith is put as the highest principle in agreement, including mediation and expecting to be implemented by all dispute parties and mediators as well. A mediator’s good faith should be carried out with earnest effort and intention formerly, instead of pushed by constitution to mandatory mediating dispute parties. This study has shown that good faith visibly implements if the mediator actively conducts the functions and responsibilities with confidentiality, volunteer, empowerment, neutrality, and exclusive solutions as the principles. Â

Full textAbstract:
Mediation analysis is a statistical method for evaluating the direct and indirect effects of an exposure on an outcome in the presence of a mediator. Mediation models have been widely used to determine direct and indirect contributions of genetic variants in clinical phenotypes. In genetic studies, the additive genetic model is the most commonly used model because it can detect effects from either recessive or dominant models (or any model in between). However, the existing approaches for mediation model cannot be directly applied when the genetic model is additive (e.g. the most commonly used model for SNPs) or categorical (e.g. polymorphic loci), and thus modification to measures of indirect and direct effects is warranted. In this study, we proposed overall measures of indirect, direct, and total effects for a mediation model with a categorical exposure and a censored mediator, which accounts for the frequency of different values of the categorical exposure. The proposed approach provides the overall contribution of the categorical exposure to the outcome variable. We assessed the empirical performance of the proposed overall measures via simulation studies and applied the measures to evaluate the mediating effect of a women’s age at menopause on the association between genetic variants and type 2 diabetes.

Full textAbstract:
This article disaggregates coalitions of third-party mediators and examines their effectiveness in interventions. First, it is argued that there is an inverted U-shaped relationship between the size of a mediating coalition and mediation effectiveness. Secondly, mediators sharing a history of conflict and distrust will transfer their past relationships to a mediation attempt, making it less effective. Consequently, states sharing friendly and co-operative ties with each other are more successful in managing conflicts. Finally, a coalition of mediators that is largely democratic should be more effective due to a shared culture of peaceful conflict resolution, inclusivity and increased communication flows. The empirical analysis using data from the Issues Correlates of War Project for 1965–2000 largely provides support for the theory.

Multiple studies have focused on Customer Experience and its relationship with Customer Loyalty. Despite such attention, two research gaps are still open with reference to the Experience-Loyalty link: the mediating role of Customer Satisfaction and the moderating role of consumer characteristics. This study employs a moderated mediation analysis of the relationship between Customer Experience and CustomerLoyalty by including Customer Satisfaction as a mediator and Shopping Enjoyment as a moderator. An online survey on almost three thousand consumers is run with reference to grocery retailing. Results show the role of Customer Satisfaction as a mediator. Shopping Enjoyment interacts with the Negative Affective Customer Experience dimension in its relationship with Customer Satisfaction.

The Spirituality Scale, Psychological Well-Being Scale, Compassion Scale, and Life Satisfaction Scale were used to collect data. Pearson Product-Moment Analysis was used to examine the links between adults' spirituality, psychological well-being, compassion, and life satisfaction. Using the Regression-Based Bootstrapping Technique and Serial Multiple Mediator Variable analysis, the researchers investigated the mediating function of compassion and life satisfaction in the link between spirituality and the psychological well-being of adults. The sequential mediation function of compassion and life pleasure was found to be significant in the link between adult spirituality and psychological well-being.

However, standard mediation analysis methods are not adequate to analyze the microbiome as a mediator due to the excessive number of zero-valued sequencing reads in the data and that the relative abundances have to sum to one. The two main challenges raised by the zero-inflated data structure are: (a) disentangling the mediation effect induced by the point mass at zero; and (b) identifying the observed zero-valued data points that are not zero (i.e., false zeros). Methods: We develop a novel marginal mediation analysis method under the potential-outcomes framework to address the issues. We also show that the marginal model can account for the compositional structure of microbiome data. Results: The mediation effect can be decomposed into two components that are inherent to the two-part nature of zero-inflated distributions. With probabilistic models to account for observing zeros, we also address the challenge with false zeros. A comprehensive simulation study and the application in a real microbiome study showcase our approach in comparison with existing approaches. Conclusions: When analyzing the zero-inflated microbiome composition as the mediators, MarZIC approach has better performance than standard causal mediation analysis approaches and existing competing approach.

In this article, we describe the use of ivmediate, a new command to estimate causal mediation effects in instrumental-variables settings using the framework developed by Dippel et al. (2020, unpublished manuscript). ivmediate allows estimation of a treatment effect and the share of this effect that can be attributed to a mediator variable. While both treatment and mediator can be potentially endogenous, a single instrument suffices to identify both the causal treatment and the mediation effects.

AbstractMediation analysis seeks to explain the pathway(s) through which an exposure affects an outcome. Traditional, non-instrumental variable methods for mediation analysis experience a number of methodological difficulties, including bias due to confounding between an exposure, mediator and outcome and measurement error. Mendelian randomisation (MR) can be used to improve causal inference for mediation analysis. We describe two approaches that can be used for estimating mediation analysis with MR: multivariable MR (MVMR) and two-step MR. We outline the approaches and provide code to demonstrate how they can be used in mediation analysis. We review issues that can affect analyses, including confounding, measurement error, weak instrument bias, interactions between exposures and mediators and analysis of multiple mediators. Description of the methods is supplemented by simulated and real data examples. Although MR relies on large sample sizes and strong assumptions, such as having strong instruments and no horizontally pleiotropic pathways, our simulations demonstrate that these methods are unaffected by confounders of the exposure or mediator and the outcome and non-differential measurement error of the exposure or mediator. Both MVMR and two-step MR can be implemented in both individual-level MR and summary data MR. MR mediation methods require different assumptions to be made, compared with non-instrumental variable mediation methods. Where these assumptions are more plausible, MR can be used to improve causal inference in mediation analysis.

The purpose of this study is to analyze the role of mediator of Guilt (in both directions: Family Interference with Work (FIW) and Work Interference with Family (WIF)) in the relationship between Conflict, Job and Life Satisfaction, also investigating the role of Enrichment as moderator. Using PROCESS Macro, the hypothesized models are tested on a sample of 161 women entrepreneurs. Both the mediating role of guilt and the moderating role of enrichment were analyzed through models of mediation and moderate mediation. Results from the analysis support the hypothesized models. Guilt FIW and Guilt WIF mediate the relationship between work Conflict and Job satisfaction, as well the relationship between Conflict and Life satisfaction, and at the same time, Enrichment moderated the mediating processes by which the Conflict affects Job and Life satisfaction via Guilt FIW and Guilt WIF. This study is one of the few that takes into consideration both Conflict and Enrichment in a sample of women entrepreneurs and examines Guilt, which many times presents itself as an “invisible” factor in studies on the work–family interface.

Studies of people with eating disorders (ED) have indicated that meaning in life is negatively associated with psychopathology, suicide risk, and emotional instability in people with ED. The aim of this study was to analyze the mediating role of meaning in life and its dimensions in the relationship between body dissatisfaction and the symptoms of ED, and to provide evidence that supports the meaning making model of eating disorders (MESTA, in Spanish). 292 Participants diagnosed with ED completed the Purpose in Life Test (PIL), the Eating Attitudes Test (EAT), and the Multidimensional Body-Self Relations Questionnaire (MBSRQ-AS). Multiple mediation analyses were performed. Meaning in life was a mediator between body dissatisfaction and ED psychopathology. The dimension of Satisfaction and meaning in life had a greater mediating role. Meaning in life could be an important variable in the maintenance of ED. The MESTA could be a useful model for understanding the psychopathology of ED.

Positive occupational health psychology (POHP) examines the mechanisms that promote the health and wellbeing of workers, in addition to the risk factors arising from work activity. The aim of this study was to analyse the mediating role of perceived stress in the effect that self-efficacy has on engagement in nurses. The sample was comprised of 1777 currently working nurses. We administered the Utrecht Work Engagement Scale (UWES), the Perceived Stress Questionnaire and the General Self-Efficacy Scale. Following bivariate correlational analysis, multiple linear regression analysis and simple and multiple mediation analysis, the results showed self-efficacy to be a powerful personal resource that positively predicts employee engagement, although the effect diminishes when there are mediating variables of stress. We found differences in the way the different aspects of stress mediated the relationship between self-efficacy and the engagement dimensions. “Energy–joy” was the strongest mediating variable for all of the engagement dimensions and this, together with “harassment–social acceptance” dampened the effect of self-efficacy on vigour and dedication, whereas “Overload” was only a mediator for dedication. As nurses work in a stressful environment, risk factors arise from work activity, so hospital management should design interventions to enhance their workers’ personal resources and improve personal and organizational wellbeing.

There is an increasing interest in investigating antecedents of employee engagement at workplace. The present article examines the role of psychological empowerment as an antecedent of employee engagement in organizations and simultaneously explored the mediating role of constructive deviance. Data was collected from 233 Indian IT sector employees. A mediation effect was documented through multiple regression analysis suggested by Barron and Kenny. Findings suggest that both psychological empowerment and constructive deviance positively affect employee engagement while constructive deviance acts as significant mediator between them. Theoretical and practical implications of the findings are discussed.

Full textAbstract:
Background: The aim was to examine the mediating role of basic psychological needs and job satisfaction in the relationship between the gender effect on health problems and psychological well-being for health professionals in Europe in 2015. Methods: Two multiple partial mediation analyses were conducted in order to test the partial mediation of both basic needs and job satisfaction, with gender as the independent variable and health problems or well-being, respectively, as the dependent variables, with a sample of health professionals. Results: Women reported lower psychological well-being and more health problems than men. The total effect of gender on both well-being and health problems was found to be significant. Regarding multiple mediation analyses: (a) the effect of gender on well-being was fully mediated by global basic need satisfaction and job satisfaction, such that gender did not present a significant direct effect and (b) the effect of gender on health problems was partially mediated by global basic need satisfaction and job satisfaction, such that the direct effect remained significant. Conclusions: The fulfillment of basic needs for autonomy, competence, and relatedness, as postulated within self-determination theory, was hypothesized to play a mediating role in the relationship between gender and well-being. Since significant gender differences in basic need satisfaction were observed, such a mediator should be controlled in order to achieve a significant relationship between gender and well-being when basic needs comes into play. The current study adds to the research emphasizing the need for satisfaction as a promising mechanism underlying for female health professionals’ well-being.

The aims of this research are 1) to analyze the existence of mediating judges in the process of civil dispute mediation based on the Supreme Court Regulation (Peraturan Mahkamah Agung/PERMA) No. 1 year 2016 regarding the mediation procedures in court; 2) to analyze the supporting and the inhibiting factors which influence the existence of mediating judges in the process of civil dispute mediation in court. This research is a normative juridical study with primary, secondary, and tertiary law materials. The manner and the instruments to collect the legal materials are using the method of documentation and document study. Data analysis is done by analyzing the research materials qualitatively. The research results and discussion show that the existence of mediating judges in the process of civil dispute mediation based on the Supreme CourtRegulation No. 1 year 2016 regarding the mediation procedures in court becomes the main choice of the parties who are in dispute. The supporting factors of the mediation by the mediating judges in a civil dispute are: human resources, economical budget, and infrastructure. The inhibiting factors of mediation by mediating judges in civil law disputes are: the parties are not present during the mediation, the number of certificated judges, and the society’s knowledge. Based on the research results and the discussion, it can be concluded that: 1) the mediation process by the mediating judges in the solving of civil law disputes becomes the main choice of the conflicting parties, 2) the supporting and the inhibiting factors which influence the existence of mediating judges in the processof mediating civil disputes are as follows: human resources, level of knowledge or the society’s understanding, facilities and infrastructure, work burden of the judges, also the regulations in the implementation of the mediation. Suggestions regarding the results of this research are: 1) increasing the service of the mediation process by the mediating judges in court, 2) increasing the quality of the human resources, increasing the facilities and the infrastructure regarding mediation, 3) and increasing the socialization to the people regarding mediation and also the issuing of regulations on mediation which are more complete and detailed.

Abstract The proliferation of actors in the business of making peace has led to an increase in the frequency of multiparty mediations, with both positive and negative consequences. The purpose of this article is to simplify the complexity that often accompanies multiparty mediations by applying the structuralist and social-psychological dichotomy of negotiations to a model of parallel mediation. I propose that coupling structuralist and social-psychological mediations together in a parallel mediation can leverage the respective strengths of each to more effectively find a negotiated solution. Given the fiscal and political realities facing peacemakers, finding ways to increase the frugality and simplicity of cooperation between mediators is essential. The limited cooperation needed in parallel mediations does just that. This article analyzes how the parallel mediation model has been applied to two conflicts, the intrastate Tajik civil war and the interstate Ecuador-Peru border dispute. This analysis identifies five characteristics that were observed in these two successful examples of parallel mediation, and serves as a starting point for additional research.

Psychological resilience refers to the capacity of individuals to cope with and successfully manage adversities. Given the links between Neuroticism as a personality dimension, Emotional Intelligence (EI) and Resilience, the present study examined the mediating role of EI in the relationship between Neuroticism and Resilience. The sampleconsisted mostly of undergraduate students (mean age = 20,55). The Big Five Inventory (BFI) (Benet- Martinez, 1998), the Greek Scale of Emotional Intelligence (GEIS) (Tsaousis, 2008) and the Resilience Scale(RS) (Wagnlid & Young, 1993) were administered to the participants (n = 123). Correlation analyses showed a significant negative correlation between Neuroticism and Resilience, as well as between Neuroticism and EI. Conversely, EI correlated positively with Resilience. As shown by the mediation analysis, ΕΙ constitutes a significant mediational factor in the relationship between Neuroticism and Resilience, suggesting that theaforementioned link is mainly due to the mediating effect of EI. In conclusion, the results demonstrate the crucial mediational role of emotion-related processes in the effect of personality on psychosocial adjustment, expanding pre-existing findings. However, further research is needed by using alternative methods and considering additional mediators and moderators.

Abstract Objectives Childhood cognitive development is influenced by biological and environmental factors. One such factor, obesity, impairs cognitive development and is associated with sleep disturbances (SDs). We examined the mediating role of SDs on the relationship between obesity and cognitive function in children from a large longitudinal study. Methods A total of 9951 children aged 9–11 years were included in this study. Children were recruited from 21 centers across the US from the Adolescent Brain Cognitive Development (ABCD) study. We assessed cognitive development using metrics for fluid (adaptation and new learning abilities), crystallized (experience-dependent abilities), and total cognitive function. Mediation analyses were conducted via linear regression modeling, with adjustment for potential confounders (sex, age, ethnicity, household income, parental education, and self-reported physical activity) for each of the 3 cognitive outcomes. Mediation significance was determined by bootstrapping. We also stratified our analyses by race (Caucasian, African-American, other racial minorities) to examine potential racial differences. Results We found a statistically significant inverse association between BMI and both total (β = −0.41, P < 0.001) and fluid (β = −0.49, P < 0.001) cognitive function. Stratified regression analyses found similar results for the Caucasians and other minorities groups, for both, fluid (Caucasian: β = −0.52, P < 0.001; other minorities β = −0.75, P = 0.01) and total cognitive function (Caucasian: β = −0.45, P < 0.001; other ethnicities: β = −0.76, P = 0.01). No association was observed among African Americans. Overall mediation analysis revealed that SDs were a partial mediator only for fluid cognitive function (P = 0.002). Further mediation analyses showed similar SDs partial mediation effects over fluid cognitive function in Caucasians (P = 0.002) and borderline significant mediation in the other minorities group (P = 0.06). Conclusions Our results suggest that SDs mediates the effect of obesity on cognitive functioning in children and that these effects vary across races, particularly as it pertains to fluid cognition. Fluid cognition is critical in childhood neurodevelopment, and further research is needed to address its long-term effects across the life course. Funding Sources None to declare.

The study group of the research consists of 354 teachers working in Istanbul in 2021. The research is carried out according to the relational survey model. Correlation analysis is carried out and tested using the suggested mediation model based on the relationship between the variables to determine the relationship between variables. According to the research findings, the agile leadership characteristics of school principals positively affect their affective occupational commitment. Additionally, mediation analysis showed that employee voice is a partial mediator between agile leadership characteristics and affective occupational commitment. This research contributes to the theory by revealing the important effects of the agile leader in the school. In the light of the findings, the implications of the agile leader, employee voice, and occupational commitment of teachers were discussed, and suggestions were made for future research.

Body fat has been reported to be associated with a higher risk of fatty liver disease (FLD). However, few studies have explored the mediating roles of an inflammatory biomarker or adipokine on the relationships. Here, we examined the potential mediating roles of high sensitivity C-reactive protein (hsCRP), tumor necrosis factor-α (TNF-α) and adiponectin (APN) in relationships between body fat and FLD in overweight and obese adults. Additionally, gender differences will be investigated. In total, 1221 participants aged 19–56 years were included in our study. Body fat percentage was measured with Dual Energy X-ray Absorptiometry (DEXA) and FLD by abdominal ultrasound. Mediation analysis was performed to assess the mediating effect of hsCRP, TNF-α and APN on the associations between BF (%) and FLD by gender differences. We found that hsCRP was significantly associated with body fat percentage in both genders (b = 0.2014, p < 0.0001 and b = 0.1804, p < 0.0001 for male and female, respectively), while hsCRP was associated with FLD only in the female group (b = 0.1609, p = 0.0109) but not in male group (b = 0.4800, p = 0.0603). We observed that hsCRP has a significant mediating effect on the association between body fat percentage and FLD (b = 0.0290, p = 0.0201, mediation ratio: 13.6%) in the female group independent of potential covariates (age, smoking, alcohol drinking and physical activity). TNF-α was not significantly associated with body fat percentage or FLD, with no mediating effect on the association between body fat percentage and FLD in either gender. In conclusion, there is a gender-specific mediation role of hsCRP in the association between body fat and FLD. HsCRP was a potential mediator on the association between adiposity and FLD in the female gender, but not in the male gender. Higher body fat was associated with a higher risk of FLD, and the inflammation level might play a potential mediating role in the association between body fat and FLD among female overweight and obese adults.

Full textAbstract:
Objective: The unprecedented nature of the COVID-19 pandemic and cessation of full face-to-face affiliation along with homebound restrictions have caused a variety of psychological distress among adolescents. Adolescents vary in the way they perceive such stressors and some respond with eating disturbances, which could reflect their dysfunctional emotion regulation strategies. The present research aimed at elucidating potential mediating pathways from perceived stress and psychological distress to emotional eating. Methods: This cross-sectional study was composed of 292 adolescents who were assessed using the Perceived Stress Scale, COVID-19-Related Psychological Stress Scale, Emotional Eating subscale of the Dutch Eating Behavior Questionnaire, and Difficulties in Emotion Regulation Scale. Correlation analyses were performed to assess the relationship between variables. ANOVA was conducted to detect differences between males and females for emotional eating. Then, a mediation analysis was conducted to assess whether emotional dysregulation was a mediator between psychological distress and emotional eating. Results: Results of path analyses indicated that a model with perceived stress and psychological distress predicting emotion eating through the mediation of emotion dysregulation was the best fit for the data (CFI=0.970, GFI=0.949, df=26, χ2=53.69, χ2/df=2.06, P>0.05, and RMSEA=0.069). Mediation analyses showed the mediating role of emotion dysregulation in the link between perceived stress and emotional eating (Sobel’s z=2.83, P<0.05) while, it could not function as a mediator between psychological distress and emotional eating (Sobel’s z=0.90, P>0.05). Conclusion: This study contributes to our understanding of the role of emotion regulation in the relationship between perceived stress and psychological distress and emotional eating in adolescents during the COVID-19 pandemic. The implication of this study is for therapeutic intervention to target emotional dysregulation of adolescents confronted with COVID-19 stressors.

Full textAbstract:
The article deals with the problem of mediation of social structural inequalities in health. According to theoretical explanations that require further empirical justification, inequalities in education — deterioration of health with its decline — may be associated with material deprivation. With a low educational status, a person does not have enough material resources necessary for high-quality nutrition, recreation and treatment. These inequalities may also arise due to the fact that poorly educated people lack the psychological reserves necessary for overcoming life's difficulties. Analysis of European Social Survey data (ESS 2012) for 27 countries, as well as the contextual factor of social protection expenditure was carried out using statistical methods of two-level modeling and regression models for mediation effects (HLM, MLmed macro, Process macro). Health inequalities in education are clearly manifest in any country. It was established that, along with education, material deprivations and especially personal resources play a significant role in differentiating the well-being of people, exerting an independent impact on it. According to the modeling results, in many countries, including the most developed, material deprivations that people with low levels of education suffer from, act as a mediator, partly clarifying the reasons for differences in health among people with different education. One of the lines of psychological mediation is also connected with material conditions — through two intermediaries, the first of which is deprivation, and the second is psychological qualities. At the same time, even when controlling all of these mediating effects, personal characteristics are an important mediator of SES inequalities, but not all over Europe, but only in countries with a relatively weak social state. In conclusion, a brief description of health inequalities and mediating effects in Russia is given.

Background:Self-efficacy, action control, and social support are considered to influence changes in physical activity levels in older adults. This study examines the relationship among these variables and explores the putative mediating and moderating mechanisms that might account for activity changes.Methods:A longitudinal study with 54 older adults (≥ 50 years of age) was carried out in Costa Rica. In a moderated mediation analysis, action control was specified as a mediator between self-efficacy and physical activity, whereas social support was specified as a moderator between self-efficacy and action control. Baseline physical activity, age, and sex were specified as covariates.Results:Action control mediated between self-efficacy and physical activity. An interaction between social support and self-efficacy on action control pointed to a synergistic effect at the first stage of the mediating process.Conclusions:The effect of self-efficacy on physical activity was partly explained by action control, providing evidence of action control as a proximal mediator of physical activity. Moreover, the moderator role of social support was confirmed: high social support appeared to compensate for low levels of self-efficacy.

Full textAbstract:
Decentering has received more attention in sports literature as a self-regulating skill capable of significantly limiting episodes of mental block in competitive situations. This contribution depicts a comparative study conducted with 375 Italian national and international athletes. The objective was to evaluate athletes’ decentralization skills across different sports and levels of competition and test a mediation model of decentering in sports with coping and emotional balance variables. Pearson bivariate correlations, linear hierarchical regression, and simple mediation analysis were conducted for all main measures (The Decentering Sport Scale, The Emotion Regulation Questionnaire, and The Coping Orientations to Problems Experienced). Outputs reported significant associations with emotional regulation and coping styles. Mediation analysis confirmed the central mediating role of decentering capacity which has indirect effects on both the coping ability of problem solving (z-value = 2.986; p = 0.003) and cognitive reappraisal (z-value = 2.779; p = 0.005). Decentering acts as a mediator between an athlete’s positive attitude, problem-orientation ability, and management of emotions in competition through cognitive reappraisal. The study highlights the significance of evaluating and enhancing decentralization skills in order to establish specific action mechanisms, which are crucial for both peak performance and the athlete’s health.

IntroductionSocial cognition has been associated with functional outcome in patients with first episode psychosis (FEP). Social cognition has also been associated with neurocognition and cognitive reserve. Although cognitive reserve, neurocognitive functioning, social cognition, and functional outcome are related, the direction of their associations is not clear.ObjectivesThe aim of the study was to analyze the influence of social cognition as a mediator between cognitive reserve and cognitive domains on functioning in FEP both at baseline and at 2 years.MethodsThe sample of the study was composed of 282 FEP patients followed up for 2 years. To analyze whether social cognition mediates the influence of cognitive reserve and cognitive domains on functioning, a path analysis was performed. The statistical significance of any mediation effects was evaluated by bootstrap analysis.ResultsAt baseline, as neither cognitive reserve nor the cognitive domains studied were related to functioning, the conditions for mediation were not satisfied. Nevertheless, at 2 years of follow-up, social cognition acted as a mediator between cognitive reserve and functioning. Likewise, social cognition was a mediator between verbal memory and functional outcome. The results of the bootstrap analysis confirmed these significant mediations (95% bootstrapped CI (−10.215 to −0.337) and (−4.731 to −0.605) respectively).ConclusionsCognitive reserve and neurocognition are related to functioning, and social cognition mediates in this relationship.DisclosureThis work was supported by the Carlos III Institute of Health and European Fund for Regional Development (PI08/1213, PI11/ 01977, PI14/01900, PI08/01026, PI11/02831, PI14/01621, PI08/1161, PI16/ 00359, PI16/01164, PI18/00805), the Basque Foundation for He

This research aimed to empirically examine the effect of parents’ social support on academic achievement through the mediation of intrinsic motivation to learn. It was hypothesized that parents’ social support positively affect academic achievement through the mediation of intrinsic motivation to learn. Researcher adapted Gordon’s Parent Subscale Social Support Questionnaire for Children Rahmi’s Parental Support Scale and Rahmi’s Intrinsic Motivation to Learn Subscale along with weighted summative asessment tests to measure academic achievement. Participants were 84 students of grade 8 from three different junior high schools in Yogyakarta. Path analysis was used to investigate the hyphotesis. Results indicated that parents’ social support was a significant predictor of intrinsic motivation to learn, b = 0.55, (p < 0.05), and that intrinsic motivation to learn was a significant predictor of academic achievement, b = 0.47, (p < 0.05). These results supported the mediational hypothesis. Parents’ social support was no longer a significant predictor of academic achievement after including the mediator, parents’ social support, b = 0.16, (p > 0.05), consistent with full mediation.

Abstract Although many social services are getting digitalized with the rapidly growing digital technology, there is little information available on the specific process of meeting personal needs in digital aging contexts. The present study examined the serial mediation model from digital assistant to unmet needs via internet self-efficacy and digital citizenship. An online survey was used to collect data in December 2021, and the sample included 223 older Korean adults aged 65 and above (M=68.79, SD=4.18, range=65-84) who owned at least one digital device. Unmet needs, the dependent variable, was the number of problems (e.g., housing, physical functioning) that participants responded to as ‘unmet.’ The independent variable was digital assistance, meaning getting help from friends or others when having problems with the digital device. The first mediator was internet self-efficacy, and the second mediator was five subtypes of digital citizenship (internet political activism, technical skills, local/global awareness, critical perspective, and networking agency). Covariates were gender, age, education, and income. SPSS Process Macro was utilized for serial mediation analysis. The result showed that only a serial mediation path from digital assistance to unmet needs via internet self-efficacy and internet political activism was significant. Additionally, a simple mediation path from digital assistance to unmet needs via internet political activism was significant. Technical skills, local/global awareness, critical perspective, and networking agency did not reveal significant mediational paths. Findings imply providing digital assistance system may be useful to reduce unmet needs among older adults by enhancing self-efficacy and political participation in the current digitalized world.

Full textAbstract:
The impact of loyalty programs on customer retention was investigated in this study. Concomitantly, the mediating effects of brand association and customer satisfaction between loyalty programs and customer retention were also tested in three ways, viz., in parallel, distinct, and sequential through a series of structural models. The study focuses on the Malaysian national car sector, and empirical data was collected from 313 Malaysian national cars users through convenience sampling. This explanatory, quantitative research adopts a questionnaire as a survey instrument, and the collected data was first subjected to normality and reliability assessment followed by confirmatory factor analysis, structural equation modeling using IBM SPSS AMOS 24. Multiple mediation analysis was then conducted, and results were confirmed through bootstrapping. Findings show that there is a significant positive impact of loyalty programs on customer retention. The brand association has a full mediation effect between loyalty programs and customer retention when tested in parallel with customer satisfaction; on the contrary, customer satisfaction demonstrated an insignificant mediation effect. On the other hand, when tested distinctly, brand association showed a partial mediating effect while there was no mediation effect of customer satisfaction. Besides, customer satisfaction and brand association demonstrated sequential partial mediation.

This study aimed to investigate the relationship between cultural orientations (horizontal/vertical -individualism/collectivism) and organizational citizenship behaviors (OCBI or OCBO). Levels of perceived organizational support (POS) was treated and evaluated as a moderator or a mediator. Data were collected based on a survey from 385 workers of various organizations. Correlation analysis for relationship between variables, hierarchical regression analysis for moderation effect of POS, and a series of simple regression analysis for mediation effect of POS were performed. The results showed the followings. First, except for OCBI, all types of cultural orientation appeared to relate to OCBO. Second, horizontal- individualism showed no indication of POS, resulted in a non-significant mediating effect on the relationship between horizontal-individualism and OCBI/OCBO. Third, except for the significant moderating effect of POS in the relationship between vertical-collectivism and OCBO, POS was found to have partial mediating effects on the relationship between cultural orientation-OCB. Limitations and further research consideration were discussed.

The aims of this study were a) to assess whether obesity acts as a mediator between i) cardiorespiratory fitness (CRF) and mean blood pressure; and ii) between between physical activity (PA) and mean blodd pressure in children and adolescents. A cross-sectional study was conducted with a 632 children and adolescents. It was measured mean blood pressure, body mass index, fat mass and waist circumference. CRF and PA was assessing with Course Navette test and ActiGraph. The analysis of the mediation was performed using Process macro for SPSS. The results indicate that obesity acts as a partial mediation in the association between CRF and mean blood pressure in 10-12 years old children (z=from -5.81 to -5.40; all p˂0.000). These results indicate that obesity acts as a complete mediator in the association between PA and mean blood pressure in 10-12 years old children (z=from -4.49 to -1.94; all p˂0.000). Our result reinforces the relevance of prevent weight increse and improve cardiorespiratory fitness level since erly age in children and adolescents to prevent high mean blood pressure. Increasing the level of physical activity can influence on obesity and cardiorespiratory fitness.

Many studies had discussed about organizational behavior such as organizational culture, motivation, organizational commitment and many others topics. However, just few studies that discussed the mediation effect of the organizational behavior variables. Work engagement is one of the important variables in organizational behavior scope. This study proposes and tests a research model that investigates and examine whether work engagement functions as a mediator of the effect of transformational leadership on job performance and OCB. These relationships are assessed through SPSS using Barron & Kenny mediation method. Data are obtained from 97 employees of pharmaceutical company in Indonesia especially Solo Raya and Madiun City. The result shows that work engagement mediates the effect of transformational leadership on job performance. Moreover, this study provides evidence to support our intended hypothesizes, by applying correlation and regression analysis which result have revealed that transformational leadership effects OCB through the mediating effect of work engagement.

This study presents the continuously spreading municipal mediation in Hungary through two community mediations as good practice. It analyses theoretical and practical course of proceedings in community decision-making processes. It presents each practical phase of community mediations, analysing the practical effects of them. It compares them with other forms of decision-making, highlighting clear advantages of community mediation both for the leadership and the given community. Through presenting the process of two case studies, two model projects are analysed in details from the perspective of the municipal decision-making organs, civil organisations and the local population. In both presented cases different problems of the community are solved through the same process protocol.
