Academic literature on the topic 'Job Demands-Resources Model'

Thesis (MCom)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: The South African health care system is tormented by various challenges ranging from income inequalities, extreme resource scarcities to discrimination and violence. This makes the health care industry a tough work environment for health care personnel to operate in. South Africa has experienced the loss of thousands of nurses over the past decade, either emigrating or leaving the nursing profession altogether (Tshitangano, 2013). Consequently, this trend drew the attention to the well-being of nurses in South Africa. The primary objective of this study was to investigate the level of work engagement among private sector nurses in the Western Cape, together with their levels of job demands, job resources, personal resources, performance and job crafting. This was done using the Job Demands-Resources model (JD-R) of work engagement. The comprehensive JD-R model was tested and the validity of the proposed relationships between the constructs was examined. Moreover, additional paths in the model were proposed and tested. Managerial implications along with practical interventions were derived from the results with the aim to increase nurse well-being and retention. An ex post facto correlational design was used to test the formulated hypotheses in this research study. Quantitative data were collected from 311 nurses employed by a private hospital group by means of non-probability convenience sampling. A self-administered paper copy survey was distributed to hospitals given that they agreed to participate in the research. The survey was voluntary, anonymous and confidential. The survey consisted of five sections and included questions from five existing questionnaires, namely, the Utrecht Work Engagement Scale (UWES-17) (Schaufeli & Bakker, 2003), the Job Demands-Resources Scale (Rothman, Mostert & Strydom, 2006), the Work Design Questionnaire (Morgeson & Humhprey, 2006), the Psychological Capital Self-Rated Version (PsyCap-24) (Luthans, Avolio, Avey & Norman, 2006), and the Job Crafting Scale (Tims, Bakker & Derks, 2012). In order to test the statistical significance of the hypotheses, the data were subjected to Structural Equation modelling and regression analyses. The results indicated that the nurses experienced a high level of work engagement, and elucidated the fact that job resources, job demands, and job crafting aspects of their jobs are in need of industrial psychologist or managerial interventions.<br>AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse gesondheidsisteem word geteister deur verskeie uitdagings wat onder andere inkomste ongelykhede, ekstreme hulpbron skaarshede, diskriminasie en geweld insluit. Dit maak die gesondheidsindustrie ʼn moeilike werksomgewing vir gesondheidspersoneel om in te werk. Suid-Afrika het duisende verpleegsters oor die laaste dekade verloor as gevolg van emigrasie, terwyl ander die professie in geheel verlaat het (Tshitangano, 2013). Gevolglik het hierdie tendens die aandag getrek na die welstand van verpleegsters in Suid-Afrika. Die primêre doel van hierdie studie was om die vlak van werksbetrokkenheid onder ʼn steekproef van privaatsektor verpleegsters in die Wes-Kaap te ondersoek, tesame met hulle vlakke van werkseise, werkshulpbronne, persoonlike hulpbronne, werksprestasie en posverryking. Die Job Demands-Resources model (JD-R) of work engagement is vir hierdie doel ingespan. Die omvattende model tesame met die geldigheid van die voorgestelde verhoudings tussen die konstrukte is getoets. Addisionele verhoudings is ook voorgestel en getoets. Bestuursimplikasies en praktiese intervensies is van die resultate afgelei en word aan bestuurders voorgelê as moontlike oplossings om verpleegsters se welstand en retensie te verhoog. ʼn Ex post facto korrelasie-ontwerp is gebruik om die geformuleerde hipoteses in hierdie studie te toets. Kwantitatiewe data is van 311 verpleegsters ingesamel wat deur ʼn private hospitaalgroep in diens geneem word. Nie-waarskynlikheid gerieflikheidsteekproeftrekking is gebruik om die steekproef te bepaal. ʼn Self-geadministreerde vraelys is ontwikkel en as harde kopie uitgestuur na dié hospitale wat ingestem het om aan die navorsing deel te neem. Die vraelys is vrywillig, anoniem en konfidensieel ingevul en het uit vyf seksies bestaan. Die vyf seksies se vrae is opgemaak uit verskeie bestaande vraelyste, naamlik, die Utrecht Work Engagement Scale (UWES-17) (Schaufeli & Bakker, 2003), die Job Demands-Resources Scale (Rothman, Mostert & Strydom, 2006), die Work Design Questionnaire (Morgeson & Humhprey, 2006), die Psychological Capital Self-Rated Version (PsyCap-24) (Luthans, Avolio, Avey & Norman, 2006), en die Job Crafting Scale (Tims, Bakker & Derks, 2012). Ten einde die statistiese beduidendheid van die hipoteses te toets, is die data deur strukturele vergelykingsmodellering en regressie-ontledings ontleed. Die resultate dui daarop dat die verpleegsters 'n hoë vlak van werksbetrokkenheid ervaar, en dat werkshulpbronne, werkseise en posverrykende aspekte van hulle werk bestuurs- of bedryfsielkundige intervensies verlang.

Although the Job Demands-Resources Model (JD-R) is the dominant theoretical framework used to understand the relationship between workplace factors and employee well-being, the cross-cultural generalizability of this model has seldom been directly tested. Therefore, this study examined whether and to what extent relationships between: 1) job demands (i.e., organizational constraints) and strain (i.e., job satisfaction, and turnover intentions) and 2) job resources (i.e., job control, participation in decision-making, direct supervisor support, senior leader support, and clear goals and performance feedback) and strain were moderated by cultural dimensions (i.e., individualism-collectivism and uncertainty avoidance). Survey data from workers in 28 countries were used to examine these questions. Results revealed that culture-level individualism-collectivism and uncertainty avoidance independently and significantly moderated some job demands-strain and job resources-strain outcomes relationships. Specifically, job control and senior leaders support was consistently and more strongly, negatively related to strain in more individualistic cultures, and participation in decision-making was more strongly, negatively related to strain in more collectivistic cultures when using cultural scores from both Hofstede and GLOBE taxonomies. In contrast, although I also uncovered some significant moderating effects of culture-level uncertainty avoidance on job demands-strain and job resources-strain relationships, the results from these analyses were often in the opposite pattern when GLOBE versus Hofstede cultural scores were used. Overall, the present study sheds light on the generalizability versus specificity of the JD-R model across cultural contexts.

Job Demands-Resources (JD-R) model (Bakker & Demerouti, 2007) provides valuable insight in identifying the antecedents and consequences of work stress and engagement. Nevertheless, the roles of personal resources and differentiated job demands (i.e., challenge demands and hindrance demands) have received less attention in the literature. Studies on their interaction effects are even rarer. This thesis reports two studies intending to fill this gap of knowledge. Study 1 aimed to develop a new scale of energy management strategies (EMS) at work and to demonstrate its reliability. A self-administered questionnaire survey adopting a cross-sectional design was conducted among 323 employees recruited from different occupations in Hong Kong. Results of exploratory factor analyses showed that the new scale comprised three main factors with good reliabilities. The aims of Study 2 were two-fold: a) to cross-validate the new EMS scale developed in Study 1; b) to investigate the roles (i.e., as antecedent and moderator) of personal resources (energy management strategies and recovery experiences) and different job demands in the JD-R model. A self-administered questionnaire survey adopting a cross-sectional design was conducted among 173 teachers in Hong Kong. Consistent with the results of Study 1, results of confirmatory factor analyses also suggested a three-factor structure of the energy management strategies scale. As hypothesized, EMS and recovery experiences were positively associated with work engagement, such association was especially strong under challenge demands. Besides, both challenge and hindrance demands were positively related to exhaustion. EMS was the only tested personal resource that could mitigate the relationship between challenge demands and exhaustion. None of the tested personal resources mitigated the relationship between hindrance demands and exhaustion. Theoretical contribution and practical implications of research findings are discussed in the thesis.

While many employees are engaged in their jobs, others suffer from poor working conditions and impaired well-being. Research suggests that job demands may impair employee work attitudes and health while both job resources and personal resources can have positive effect. Therefore, the aim of this study was to examine the relative importance of job demands, job resources, and a personal resource (self-efficacy) for employees’ health and motivation at work. Questionnaire data were collected from white-collar employees of a Swedish construction company (n = 156). Results of hierarchical multiple regression analyses showed the relative importance of job demands, job resources and personal resources. The job demands were negatively related to health and motivation at work, while the job resources and the personal resource were linked to better health and motivation. The findings generally supported the hypotheses. The specific types of demands and resources were significant varied across outcomes and, unexpectedly, workload was positively correlated with job performance. The findings contribute to a growing literature which indicates that lower job demands and access to both job resources and personal resources may improve employees' health and motivation at work.

<p> Probation officers are subject to a great deal of stress. The goal of this study is to examine occupational stress and burnout by testing and modifying the Job Demands-Resources model. This model suggests that organizational characteristics have implications for individual outcomes related to stress. However, the model neglects the role of individual factors, such as resilience and coping. In coordination with the Probation Association of New Jersey, this study tests the modified model using cross-sectional surveys from 184 probation officers. Results suggest that resilience influences how individuals perceive and cope with stress, maladaptive strategies lead to burnout, and burnout is associated with increased health concerns and turnover.</p><p>

Organisations in the chemical industry face many demands. They have to distinguish themselves from their competitors in the market through technological advancement, market changes and the constant drive to be the best. Other demands include political pressures, e.g. employment equity and diversity management. Furthermore they have to attempt to reduce costs as well as to increase productivity. These pressures may have either a negative or positive effect on employees which could in turn impact on their energy and motivation. Higher job demands and a lack of job resources could result in high levels of exhaustion, demotivation, dissatisfaction and disengagement. Job demands refer to those physical, psychological or organisational aspects of the job that require specific effort and are associated with physiological and psychological costs. Job resources refer to the aspects of the job that may be functional in meeting task requirements and may reduce the physiological and psychological costs; they may also stimulate growth as well as the development of an individual. The objective of this study was to test a structural model of work-related well-being showing the relationships amongst the variables of job demands, job resources, exhaustion, mental distance, vitality, work devotion, health and organisational commitment. A cross-sectional survey design was used. The participants (JV=265) included employees working for a business within the chemical industry. The South-African Employee Health and Wellness Survey (SAEHWS) was used to gather data on the work-related well-being of employees. Descriptive statistics, Cronbach's alpha coefficients, correlation coefficients and structural equation modelling were used to analyse the data. The results indicated that high job demands and insufficient job resources resulted in high levels of burnout (exhaustion and mental distance), which led to physical and psychological ill health. Adequate job resources on the other hand resulted in work-related well-being (low burnout and high work engagement), which in turn resulted in organisational commitment. Growth opportunities within the job and organisational support played an important role in the well-being of the employees. Recommendations for future research were made.<br>Thesis (M.A. (Industrial psychology))--North-West University, Potchefstroom Campus, 2009.

This study examines the determining factor of nurses' occupational stress in public hospitals in Saudi Arabia. Despite the increasing number of occupational stress studies in the healthcare industry, occupational stress studies are still at an early stage of development in Saudi Arabia, and further research is recommended. The objectives of this research are: (1) to identify the occupational stress levels among nurses in public-sector hospitals in Saudi Arabia; (2) to examine the influence of job demands on the anxiety and turnover intention of nurses working in public-sector hospitals in Saudi Arabia; (3) to investigate the influence of job resources on the turnover intention and happiness of nurses working in public-sector hospitals in Saudi Arabia; (4) to determine the mediating effects of emotional exhaustion on the relationship between job demands and anxiety and turnover intention on nurses working in public-sector hospitals in Saudi Arabia; and (5) to ascertain the mediating effects of work engagement on the relationship between job resources and the turnover intention and happiness of nurses working in public-sector hospitals in Saudi Arabia. The study was conducted as a two-stage empirical study employing sequential exploratory mixed-methods approach starting with interviews with 15 nurses, analysing the data then revising the questionnaire and distributing to a sample of nurses at five hospitals. The study used thematic analysis to analyse the qualitative data and the Statistical Package for the Social Sciences (SPSS) and AMOS to analyse the 512 questionnaires. The conceptual model was validated through Structural Equation Modelling (SEM), which includes two kinds of models: the measurement model or confirmatory factor analysis (CFA), and the structural model which is conducted to approve the hypotheses and the performance of the suggested conceptual framework. The study findings indicated that the level of nurses' stress is very high and has negative outcomes if the job demands (stressors) exceed the nurses' abilities. Emotional demands, work-family conflict and workload are the main job demands identified. Procedural fairness and perceived organizational support are identified as the main job resources. This study also examines the mediation role of emotional exhaustion and work engagement. More specifically, its shows that emotional exhaustion mediates the relationship between emotional demands, work-family conflict, workload and anxiety, whereas emotional exhaustion only mediates the relation between work-family conflict and turnover intention. Conversely, work engagement mediates the relation between procedural fairness and turnover intention and happiness. Contributions of the study, research and practical implications, and future research directions are also discussed.

The present dissertation focuses on burnout and work engagement among teachers, with especial focus on the Job-Demands Resources Model: Chapter 1 focuses on teacher burnout. It aims to investigate the role of efficacy beliefs using negatively worded inefficacy items instead of positive ones and to establish whether depersonalization and cynism can be considered two different dimensions of the teacher burnout syndrome. Chapter 2 investigates the factorial validity of the instruments used to measure work engagement (i.e. Utrecht Work Engagement Scale, UWES-17 and UWES-9). Moreover, because the current study is partly longitudinal in nature, also the stability across time of engagement can be investigated. Finally, based on cluster-analyses, two groups that differ in levels of engagement are compared as far as their job- and personal resources (i.e. possibilities for personal development, work-life balance, and self-efficacy), positive organizational attitudes and behaviours (i.e., job satisfaction and organizational citizenship behaviour) and perceived health are concerned. Chapter 3 tests the JD-R model in a longitudinal way, by integrating also the role of personal resources (i.e. self-efficacy). This chapter seeks answers to questions on what are the most important job demands, job and personal resources contributing to discriminate burned-out teachers from non-burned-out teachers, as well as engaged teachers from non-engaged teachers. Chapter 4 uses a diary study to extend knowledge about the dynamic nature of the JD-R model by considering between- and within-person variations with regard to both motivational and health impairment processes.

Includes bibliographical references.<br>Employee wellbeing has become a major concern for organisations globally, with an increased interest in the prevention of burnout and the maximisation of employee work engagement. Burnout and work engagement are of particular importance to organisations due to their respective negative and positive outcomes on employees. While burnout is linked to high turnover intentions and low performance, work engagement has a positive correlation with job satisfaction, life satisfaction and extra-role performance. Accordingly, the job demands-resources (JD-R) model was developed as a theoretical framework, highlighting those work characteristics that predict employee work engagement and burnout. A main criticism of the JD-R model is its lack of consideration for the impact of personal resources on employee wellbeing. Emanating from this concern, the current study used the conservation of resources (COR) theory to empirically test whether the personal resource of psychological capital or PsyCap (conceptualised as self-efficacy, hope, optimism and resilience) interacted within the health impairment and motivation processes of the JD-R model. More specifically, this study examined whether PsyCap moderated the relationship between job demands and burnout and mediated the relationship between job resources and work engagement.
