This study provides a summary of 45 exploratory and confirmatory factor-analytic studies that examined the internal structure of scores obtained from the Maslach Burnout Inventory (MBI). It highlights characteristics of the studies that account for differences in reporting of the MBI factor structure. This approach includes an examination of the various sample characteristics, forms of the instrument, factor-analytic methods, and the reported factor structure across studies that have attempted to examine the dimensionality of the MBI. This study also investigates the dimensionality of MBI scale scores using meta-analysis. Both descriptive and empirical analysis supported a three-factor model. The pattern of reported dimensions across validation studies should enhance understanding of the structural dimensions that the MBI measures as well as provide a more meaningful interpretation of its test scores.

The purpose of this study was to synthesize internal consistency reliability for the subscale scores on the Maslach Burnout Inventory (MBI). The authors addressed three research questions: (a) What is the mean subscale score reliability for the MBI across studies? (b) What factors are associated with observed variance in MBI subscale score reliability? (c) What are the implications for appropriate use based on MBI subscale mean internal consistency estimates? Of the 221 studies reviewed, 84 provided alpha coefficients and were used in the current analysis. Results suggest that mean alpha estimates across subscales generally fell within the .70 to .80 range. Scale variance and language most often accounted for the variance in coefficient alpha, although some variations were apparent between subscales. Of the three MBI subscales, Personal Accomplishment and Depersonalization mean alpha estimates were well below recommended levels for high-stakes decisions, such as the diagnosis of burnout syndrome. Recommendations for the use of the current version of the instrument’s scale scores as well as suggestions for scale refinement are provided.

The Survey of Perceived Organizational Support (SPOS) is a unidimensional measure of the general belief held by an employee that the organization is committed to him or her, values his or her continued membership, and is generally concerned about the employee's well-being. In the interest of efficiency, researchers are often compelled to use a minimum number of SPOS items in their studies. This study reports on a reliability generalization across 62 published studies using the SPOS. Findings suggest that number of SPOS items and mean age of the sample are statistically significant in the relationship to reliability estimates. Additionally, mean age accounted for significant variance in internal consistency estimates over and above the number of items used.

We report findings from a validation study of the translated and culturally adapted Serbian version of Maslach Burnout Inventory‐Human Services Survey (MBI‐HSS), for a sample of anesthesiologists working in the tertiary healthcare. The results showed the sufficient overall reliability (Cronbach’s α = 0.72) of the scores (items 1–22). The results of Bartlett’s test of sphericity (χ² = 1983.75, df = 231, p < 0.001) and Kaiser‐Meyer‐Olkin measure of sampling adequacy (0.866) provided solid justification for factor analysis. In order to increase sensitivity of this questionnaire, we performed unfitted factor analysis model (eigenvalue greater than 1) which enabled us to extract the most suitable factor structure for our study instrument. The exploratory factor analysis model revealed five factors with eigenvalues greater than 1.0, explaining 62.0% of cumulative variance. Velicer’s MAP test has supported five‐factor model with the smallest average squared correlation of 0,184. This study indicated that Serbian version of the MBI‐HSS is a reliable and valid instrument to measure burnout among a population of anesthesiologists. Results confirmed strong psychometric characteristics of the study instrument, with recommendations for interpretation of two new factors that may be unique to the Serbian version of the MBI‐HSS.

In this study, we utilized reliability generalization procedures to examine internal consistency estimates across 3 scales measuring the belief in a just world. The distribution of reliability estimates for the measures suggest low to moderate ranges of internal consistency reliability coefficients. The Global Belief in a Just World Scale ( Lipkus, 1991 Lipkus, I. 1991. The construction and preliminary validation of a Global Belief in a Just World Scale and the exploratory analysis of the Multidimensional Belief in a Just World. Personality and Individual Differences, 12: 1171–1178. [Crossref], [Web of Science ®] [Google Scholar] ) produced the highest average reliability score (α = .81) compared to the Just World Scale ( Rubin & Peplau, 1973 Rubin, Z. and Peplau, A. 1973. Belief in a just world and reactions to another's lot: A study of participants in the national draft lottery. Journal of Social Issues, 29: 73–93. [Crossref], [Web of Science ®] [Google Scholar] ; α = .64) and the Just World Scale Revised ( Rubin & Peplau, 1975 Rubin, Z. and Peplau, L. A. 1975. Who believes in a just world?. Journal of Social Issues, 31: 65–89. [Crossref], [Web of Science ®] [Google Scholar] ; α = .68).

This study examines the geopolitical agency of Palestinian children. Mixed methodology was used to identify the etiologies contributing to processes of political socialization. Both qualitative and qualitative methods are equally distributed throughout this research. Focus groups and interviews with 12 Palestinian children, aged 10 to 13 years, living in refugee camps, villages, and cities in the West Bank were used to develop a survey instrument. The survey was administrated to 1% of the students attending school, Grades 5 to 7, in the West Bank, Palestine. The use of mixed methodology revealed the interconnectedness of formal and informal political socialization that produces the geopolitical agency of Palestinian children. Findings elaborated on the processes and the relationships used to describe children's geopolitical agency.
