Malgré quelques limites, le coefficient alpha de Cronbach reste l'indicateur de fidélité d'échelle le plus utilisé. Le but de cet article est de passer en revue l'ampleur des coefficients alpha obtenus dans les recherches comportementales empiriques, de confronter ces valeurs obtenues aux règles et aux recommandations préconisées par des chercheurs tels que Nunnally (1967, 1978), et d'apporter des éclairages sur les caractéristiques de plan de recherche susceptibles d'influencer la taille du coefficient alpha. Les moyennes des coefficients alpha rapportés dans la littérature vont de 0,70 pour les valeurs et les croyances, à 0,82 pour la satisfaction au travail. Hormis quelques exceptions, il n'existe aucune relation substantielle entre l'ampleur du coefficient alpha et les caractéristiques des plans de recherche examinés.

This study aims to describe the effects of variability through data simulation to determine which aspect of variability that maximizes coefficient of Cronbach Alpha reliability. Cronbach Alpha is widely used for estimation of reliability, in recent still. This study served a conceptual and practical simulation for estimating the profound aspect of Cronbach Alpha coefficient relating to the variability of the data. This study carried out with data simulated using the rand between method by Microsoft Excel then simulate different categorical data responses to different range of items by manipulating sample size, range, number of items, variance and standard deviation. The results show that number of variance and standard deviation of data had the most profound aspect of Cronbach Alpha's reliability other than range. The increasing number on some aspect shows that standard deviation and variance has the stability to shows the positive correlation with the coefficient of Cronbach Alpha reliability other than range.

Cronbach alpha and Cohen kappa were compared and found to differ along two major facets. A fourfold classification system based on these facets clarifies the double contrast and produces a common metric allowing direct comparability. A new estimator, coefficient beta, is introduced in the process and is presented as a complement to coefficient alpha in estimating the psychometric properties of test scores and ratings.

Object This study was undertaken to assess the reliability of observations of postoperative photographs in assigning House-Brackmann scores as outcome measures for patients following resection of vestibular schwannomas. Methods Forty pictures of differing facial expressions typically elicited from patients for assigning House-Brackmann scores were individually evaluated by neurosurgery residents and faculty members at the University of Alabama at Birmingham; a score was assigned to each picture by the individual raters. The interrater reliability was measured using the Spearman correlation coefficient, Kendall coefficient of concordance, and kappa statistic; internal consistency was calculated using the Cronbach alpha reliability estimate. Results The Spearman correlation coefficients showed strong positive association among raters, with a range of values of 0.66 to 0.90. Internal consistency measured by the Cronbach alpha coefficient was excellent (α = 0.97). The Kendall coefficient of concordance for the ordinal grades suggested a substantial degree of agreement among the raters (w = 0.76, p < 0.001). Conclusions Static postoperative photographs are a reliable outcome measure for determining facial nerve function after vestibular schwannoma resection and may serve as a surrogate for the dynamic patient interview.

Zimet's knowledge of AIDS scale was completed anonymously by 2,209 university students to assess whether a split-half approach in which items in each half were matched for content would provide better estimates of reliability than other methods. Analysis indicated that the odd-even Spearman-Brown split-half reliability coefficient was lower than both the alpha coefficient and the content-based split-half coefficient. The Cronbach alpha was similar to the content-based Spearman-Brown reliability coefficient.

AbstractTo validate PSS-14 Romanian version and identify reliable and simple tools which can be used for measuring stress level in current practice. Materials and methods: PSS-14 Romanian version, a five-level qualitative scale and a decimal scale were applied to 928 Romanian subjects, selected through the “snowball method”, for measuring perceived stress level. Intraclass correlations and Alpha Cronbach coefficient were used for assessing internal consistency of PSS-14 and Spearman coefficient for testing correlations.Results: Cronbach’s Alpha values for PSS-14 items were ≥0.700 (0.746 and 0.878 for standardized coefficient), showing internal consistency. Spearman correlation (0.375, p<0.05) revealed positive, medium and significant correlations between simple scales scores and PSS-14 scores.Conclusions: PSS-14 RO is an adequate tool for measuring the perceived stress level in Romanian patients. When appropriate, a simple Likert qualitative scale or a decimal self-assessment scale can quickly provide to health professionals results with indicative value.

The aim of this study is to develop a Portuguese version of the OHIP-49 to be used in Brazil. The adopted methodology involves translation, back-translation, revision of the first version, cultural adaptation and evaluation of its measurement properties. The questionnaire was administered in interviews with 60 year-old and older Brazilian people. The Kendall-tau correlation coefficient was used to assess reproducibility; the Cronbach alpha coefficient was used to verify internal consistency and the Kruskal-Wallis and Mann-Whitney U tests were used to assess validity. Reproducibility was shown to be statistically significant, with coefficients ranging from 0.72 to 0.74 between dimensions of three interviews. The Cronbach alpha coefficients were 0.96 and 0.90 respectively for the dimensions of the interviews and for total items. Constructive validity, demonstrated through a comparison between the questionnaire dimensions and the clinical parameters, showed statistical significance for "presence of carious lesion" (p < 0.05). Significant correlations between similar dimensions of the OHIP-49 and the SF-36 were also identified (p < 0.05). In the present sample, the Portuguese version of the OHIP-49 presented results similar to those found in the literature and proved to be a reproducible and valid parameter for evaluating the impact of oral conditions on the quality of life of Brazilians.

Introduction: Women's screening beliefs play an important role in their performance. Since a short form questionnaire is necessary in the assessment of screening beliefs in Iranian society, this study was conducted with the aim of psychometric evaluation of the Breast Cancer Screening Beliefs Questionnaire (BCSBQ) among Iranian women. Methods: In this cross-sectional methodological study, 300 Iranian women who were aged 18 years or older, and who were attending healthcare centers of Shahid Beheshti University of Medical Sciences, were selected in 2017-18. After a backward-forward translation procedure of BCSBQ was carried out, the face, content and construct validity of breast cancer-screening beliefs questionnaire were evaluated. In addition, the reliability was measured using the Cronbach's alpha and intra class correlation coefficients. Results: The results of the exploratory and confirmatory factor analysis were used to extract three distinct factors, including: attitude, knowledge, and barriers to screening. The three-factor model fit was accepted for all factors based on standard indices (RMSEA = 0.12, χ2 = 2.832, GFI = 0.87, AGFI = 0.8, CFI = 0.94, NFI = 0.92). In addition, the instrument’s reliability was measured using the Cronbach's alpha coefficient. The instrument had an appropriate Cronbach alpha (0.78). The interclass correlation coefficient was obtained to be 0.93 within a range of 0.83-0.97. Conclusion: The three-factor structure of the BCSBQ-12 had appropriate validity and reliability among Iranian women. Considering its appropriate psychometric properties, this instrument can be employed in subsequent studies to measure women's breast cancer screening beliefs in Iran.

Introduction. Health-related quality of life (HRQL) of chronic patients has been researched as the ultimate goal of modern treatment of chronic diseases to improve patients? quality of life. Objective. The objective was to assess the reliability of the Serbian version of the Sickness Impact Profile (SIP) questionnaire on the sample of patients with chronic viral hepatitis. Methods. The research covered 102 patients with chronic hepatitis (47 type B and 55 type C). The assessment of the reliability of the SIP questionnaire was performed by testing the internal consistency of the questions by calculating the Cronbach?s alpha coefficient. The factor analysis was used to assess whether the grouping of the questions within dimensions matches the distribution of the questions in the original English version of the questionnaire administered to U.S. patient population. Results. The Cronbach?s alpha coefficient for the entire questionnaire is 0.925, 0.869 for the physical dimension, and 0.857 for the psychosocial dimension. After running a factor analysis of the psychosocial dimension, ?emotional instability? was extracted as the key factor, confirming the results of previous research. Compared with the English version of the questionnaire, the Cronbach?s alpha coefficient of the Serbian version does not diverge significantly, whereas the factor analysis confirms the classification of the questionnaire into two dimensions. Conclusion. Our study has shown that the Serbian version of the SIP questionnaire is a reliable tool for assessing the HRQL of patients with chronic hepatitis B and C before starting treatment.

OBJECTIVES: To assess the reliability and validity of the Brazilian version of the Attentional Function Index. METHOD: Methodological study. The sample was made up of 138 students from an undergraduate nursing course. The psychometric properties were assessed through the convergent construct validity, using the Brazilian version of the Attentional Function Index and the Portuguese-language version of the Profile of Mood States instrument, while the reliability was measured by its internal consistency, expressed by the Cronbach Alpha Coefficient. RESULTS: The Cronbach Alpha Coefficient was 0.86 for the total score, and varied from 0.64 to 0.86 in the three subscales. A strong significant negative correlation (r=-0.64; p<0.0001) was obtained for the convergent validity. CONCLUSION: The Brazilian version of the Attentional Function Index resulted in satisfactory levels of validity and reliability, demonstrating its viability for use in practice and in undertaking further research.

Full textAbstract:
Background Work addiction is a significant public health problem with a growing prevalence. The Work Addiction Risk Test (WART) is the gold standard questionnaire to detect workaholism. Objective The main objective of this study was to validate the French version of the WART. Methods Questionnaires were proposed to voluntary French workers using the WittyFit software. There were no exclusion criteria. The questionnaire was administered anonymously for initial validity testing and readministered one week later for test-retest reliability. We also assessed the workers’ sociodemographic characteristics, as well as other measurements for external validity, such as stress, well-being, and coaddictions to tobacco, alcohol, and cannabis. Several psychometric properties of the French-WART were explored: acceptability, reliability (internal consistency [Cronbach alpha coefficient] and reproducibility [Lin concordance coefficient]), construct validity (correlation coefficients and principal component analysis), and external validity (correlation coefficients). Results Among the 1580 workers using WittyFit, 187 (11.83%) agreed to complete the WART questionnaire. Of those, 128 completed the test-retest survey (68.4%). Acceptability found that all respondents had fully completed the questionnaire, with few floor or ceiling effects. Reliability was very good with a Cronbach alpha coefficient at .90 (internal consistency) and Lin concordance coefficient at .90 (95% CI .87-.94] with a difference on the retest of .04 (SD 4.9) (95% CI −9.6 to 9.7) (reproducibility). We identified three main dimensions (construct validity). Relationships between WART and stress and well-being confirmed its external validity. Conclusions The French version of the WART is a valid and reliable instrument to assess work addiction with satisfactory psychometric properties. Used in occupational medicine, this tool would allow the diagnosis of work addiction and can be easily implemented in current practice.

ABSTRACT To evaluate the functioning of individuals with diabetes mellitus (DM) using a biopsychosocial model, recommended by the World Health Organization and sustained in the theoretical-conceptual framework of the International Classification of Functioning, Disability and Health (ICF), this study proposed validating the Brazilian version of WHODAS 2.0 (World Health Organization Disability Assessment Schedule). The 36-item version of WHODAS 2.0 was applied to 100 participants with DM as validation procedures, using the measurement of Diabetes Quality of Life Measure (DQOL-Brazil) and a dynamometry. The psychometric properties analyzed were internal consistency (Cronbach Alpha coefficient) and convergent and divergent external validity (Spearman correlation coefficient). The internal consistency analysis was appropriate, except for the “having a good relationship with people” domain in the alpha Cronbach coefficient. External validity analysis confirmed the convergence hypothesis between the correlate domains of the different tools. The exception was the “life activities” domain (WHODAS) with the left-hand dynamometry. The Brazilian version of the WHODAS 2.0 instrument is a valid instrument to assess the functioning of these individuals.

OBJECTIVE: To evaluate internal consistency and temporal stability trough test re-test reliability of the Portuguese version of the Social Phobia and Anxiety Inventory (SPAI) in a heterogeneous Brazilian sample. METHODS: After informed consent, the translated and adapted version of the SPAI Portuguese was tested and re-tested at a 14-day interval in a sample of 225 university students, both genders, from 4 different undergraduate courses. After double data entry, statistical analysis included Cronbach's alphas, Pearson and intra-class correlation coefficients. RESULTS: The studied sample consisted of 213 students from 4 sub-samples: 95 law students, 31 social communication students, 54 civil engineering students and 33 dental medicine students. The mean age was 23 (±6) years and 110 (51.6%) were female. The Cronbach' alpha was 0.96, no difference for both genders. The differential (total) score of the SPAI Portuguese showed Pearson coefficient 0.83 (95% CI 0.78-0.87) and Intra-class coefficient 0.83 (95% CI 0.78-0.86). There was no statistical difference in Pearson coefficients between genders (p = 0.121) and the 4 sub-samples (p = 0.258). CONCLUSION: The results do not ensure validity, however, the SPAI Portuguese version presented a good content homogeneity with satisfactory level of internal consistency. The temporal stability evaluated was substantial.

The purpose of this study was to investigate both the internal consistency and temporal reliability of the Measure of Self-actualization of Potential. Results from the initial pilot study ( n = 414) used to develop the inventory are compared with those of a new sample ( n = 156) designed to evaluate its stability. Responses from the new sample support our initial findings of moderate to relatively high alpha coefficients for the two main scales and five subscales. Test-retest reliability for the new set of responses indicates high stability, with intraclass correlation coefficients ranging from .74 to .88. For the over-all scale, Cronbach alpha reaches .90 and the intraclass coefficient .87. In addition to better psychometric properties, the new inventory has two other advantages over the Personal Orientation Inventory, fewer items and a self-report format.

ABSTRACTCaregivers of demented patients are under significant stress along with physical, psychological or social problems. Standardized and validated instruments are required for measuring consequences of caregiving or efficacy of support interventions. Reliability of French translation of these instruments has to be verified in order to confirm their psychometric properties. The goal of the present study is to assess reliability of the French translation of three instruments designed for evaluation of caregivers of demented patients. The Zarit's Burden Interview (BI) is a 22-items scale measuring the subjective burden of the caregiver. The Revised Memory and Behavior Problems Checklist (RMBPC), a 53 item scale, measures frequency of memory and behaviour problems of demented patients and the caregiver's reaction to these problems, which is another mean of burden assessment. The Alzheimer's Disease Knowledge Test (ADKT) assesses knowledge of caregivers about demented diseases and resources available using 20 multiple choice questions. A reliability study was conducted on a sample of 40 caregivers. The caregivers were questioned twice, the second time after one (N = 26) or eight (N = 14) weeks. The BI internal consistency (Cronbach alpha) yielded a coefficient of 0.85 and test-retest reliability (intra-class correlation coefficient) was 0.89. The RMBPC's Cronbach Alpha was 0.93 for frequency and 0.94 for reaction. Intra-class correlation coefficients were 0.77 (frequency) and 0.90 (reaction) for RMBPC and 0.71 for ADKT.

Introduction. Most dietary questionnaires are not created for use in a clinical setting for an adult health exam. We created the Healthy Eating Vital Sign (HEVS) to assess eating behaviors associated with excess weight. This study investigated the validity and reliability of the HEVS. Methods. Using a cross-sectional study design, participants responded to the HEVS and the Block Food Frequency Questionnaire (BFFQ). We analyzed the data descriptively, and, with Pearson’s correlation and Cronbach coefficient alpha. Results. We found moderate correlation (rho>0.3) between multiple items of the HEVS and BFFQ. The Cronbach's alpha was 0.49. Conclusion. Our results support the criterion validity and internal reliability of the HEVS as compared to the BFFQ. The HEVS can help launch a dialogue between patients and providers to monitor and potentially manage dietary behaviors associated with many chronic health conditions, including obesity.

A 12-item Social Interaction Questionnaire was developed to measure the social interactions among trainers and mothers of children with disabilities in Dousa-hou camps. Dousa-hou is a Japanese psychological rehabilitation method which is widely used for children with mental retardation, cerebral palsy, and autism in Japan and other Asian countries. The primary focus of the rehabilitation method is to improve bodily movements, posture, and social support to patients and their first-degree relatives as well as promoting social interaction among participants. Two factors of interaction, (1) educational and daily life matters and (2) health and care matters, emerged through factor analysis. Cronbach coefficient alpha of the questionnaire was .91. The back-translated version of the Social Interaction Questionnaire also yielded two factors and Cronbach coefficient alpha of .87. It was found that mothers or first degree relatives ( N = 138; M = 43.5 yr., SD = 12.3) of the patients reported more social interaction than trainers when interacting with their child's trainer, supervisor, other trainers, and other mothers during six-day Dousa-hou camps.

Background Nomophobia or phobia of no mobile phone is the fear of being without a mobile phone or being unable to contact others via a mobile phone. It is a newly emerging psychiatric disorder among mobile phone users. Objective There are no psychometric scales available in China for examining nomophobia, although China has become the largest mobile phone handset consumer market in the world. Therefore, this study aimed to translate the original English version of a psychometric scale into Chinese and further examine its reliability and validity among Chinese college students. Methods The original version of the Nomophobia Questionnaire (NMP-Q) was first translated into Chinese using the backward and forward translation procedure. An exploratory factor analysis (a principal component analysis plus varimax rotation) and a confirmatory factor analysis (CFA) were performed to examine the underlying factor structure of the translated questionnaire. The internal consistency reliability of the scale was determined by computing the Cronbach alpha coefficient, the test-retest reliability, and the corrected item-total correlation. A multivariate regression analysis was used for examining associations between nomophobia and independent variables among the college students. Results A total of 2000 participants were included in the study. Their ages ranged from 16 to 25 years, with 51.95% (1039/2000) being male participants. The Chinese version of NMP-Q retained 18 items. The eigenvalues, total variance explained, and scree plot jointly support a 4-factor structure of the translated questionnaire. The CFA reached the adaptive standard, and the discriminant validity of the scale was good. The Cronbach alpha coefficient of this scale was .925, and the Cronbach alpha coefficients of the subscales were .882, .843, .895, and .818. The test-retest reliability was 0.947. Corrected item-total correlation ranged from 0.539 to 0.663. The significant predictors for each of the dimensions of nomophobia and total score of the questionnaire were the average number of hours spent on a mobile phone daily and gender. Conclusions The Chinese version of the NMP-Q exhibited satisfactory psychometric properties.

The concept of providing a safe internet refers to an attempt to prevent and protect against the damages that may come from any possible harmful content, person and entities in the internet environment. Nowadays in the face of increasing internet use, it is important for individuals who have children to provide safe internet use to their children in terms of preventing their children from being psychologically and socially affected negatively. Therefore, it is very important to develop a scale in order to see the competence of parents in providing safe internet. Purpose of this study is to develop Parent's Safe Internet Providing Competency Scale and to examine its validity and reliability. This research was conducted on a total of 422 participants, 289 females and 133 males, aged between 18 and 59. In process of developing this scale, a 23-item pool was created first and then these items were examined in terms of their grammar, intelligibility, and whether they really measure recognition in couple relationships, and a 20-item application form was obtained in the end. Corrected item-total correlation coefficients were calculated for item analysis of scale. Construct validity of scale was examined by exploratory factor analysis and its reliability with Cronbach alpha internal consistency reliability coefficient. Validity and reliability analyzes were made with SPSS 18. As a result of exploratory factor analysis applied for construct validity of scale, a one-dimensional and 20-item measuring tool with an eigenvalue of 11.3 was obtained explaining % 57 of total variance. KMO sample fit coefficient of scale was found to be .96. Factor loads of scale were ranged between .59 and .84. Cronbach alpha internal consistency reliability coefficient was found to be .96. Corrected item-total correlation coefficients of scale range from .55 to .82. These results show that scale is a valid and reliable measurement tool.

The data were analyzed in SPSS 21 using descriptive statistics, exploratory factor analysis (EFA), dependent t test, and Cronbach alpha coefficient. Results: A 22-item questionnaire was designed and the items were scored using a five-point Likert-type scale (Min=22, Max=120). Finally, the Kaiser-Meyer-Olkin value, Bartlett’s test of the Sphericity value, the internal consistency of the tool based on Cronbach’s alpha coefficient, and the intra-cluster correlation coefficient were 0.801, 4035.810, 0.811, and 0.81, respectively. Conclusions: In general, the present tool can reliably predict HBV infection in pregnant women thus its application is recommended in preventing relevant complications.
