The Reliability of Maslach Burnout Inventory in Arab Studies: Reliability Generalization Meta-Analyses Study

Abstract

The current study aimed to identify the mean effect size of the alpha coefficient for the overall reliability of the MBI scale, and for the sub-dimensions; Emotional exhaustion, depersonalization, and lack of personal achievement through the analysis of (32) studies in which the inclusion criteria were met. The results of the research indicated that the mean alpha coefficient across the studies (n = 32) for overall reliability and dimensions; Emotional exhaustion, depersonalization, and lack of personal achievement were 0.83, 0.83, 0.78, and 0.77, respectively. It indicated that the mean alpha coefficient of the MBI scale varied significantly according to the participants in favor of school principals, and according to gender in favor of the mixed (male/female), and according to the country of application for studies conducted in North and East African countries, while it did not vary according to the sample size. It also showed that the mean alpha coefficient of the emotional exhaustion dimension varied according to the participants in favor of the teachers. The results also showed that there were no differences in the mean alpha coefficient of the dimension of emotional exhaustion according to the factors of sample size, gender, and country of application, and indicated that there were no significant differences in the mean alpha coefficient of the dimensions of depersonalization and lack of personal achievement according to the factors of sample size, participants, gender and country of application.
