The validity and reliability of the copenhagen burnout inventory for examination of burnout among preschool teachers in serbia

Abstract

Introduction: Burnout syndrome is being increasingly recognized as a factor that affects the health status and is being examined among different professional groups. Consequently, there is a need for a reliable and valid instrument for its examination. Teachers are emerging as a professional group of interest in the area of burnout research, so the aim of this study was to assess the validity and reliability of the Serbian version of Copenhagen burnout inventory among teachers at preschool institutions in Serbia. Materials and Methods: This research was conducted as a cross-sectional study between October 2018 and April 2019 on a nationally representative sample of preschool teachers in Serbia. The internal consistency of the scale was assessed using Cronbach’s alpha, and the construct validity was examined using exploratory (EFA) and confirmatory factor analyses (CFA). Results: The average score on total burnout was 39.1 ± 17.0, while the average score per scales on the Copenhagen burnout inventory was: 41.3 ± 18.7 for personal burnout, 41.2 ± 15.9 for work-related burnout, and 34.7 ± 22.0 for client-related burnout. The Cronbach’s alpha for the entire scale was 0.936, the Cronbach’s alpha for the personal burnout scale was 0.906, and the Cronbach’s alpha for the work-related burnout scale was 0.765, while the Cronbach’s alpha for the client-related burnout scale was 0.901. The EFA for the CBI showed three factors. The factor loadings varied from 0.575 to 0.859. The three factors explained 67.17% of the variance. Conclusions: Our study showed that the three-factor Serbian version of the Copenhagen burnout inventory can be used for the assessment of burnout syndrome among teachers.
