Psychometric properties and structural validity of the Serbian version of the Copenhagen Burnout Inventory (CBIser)

Abstract

Copenhagen Burnout Inventory (CBI) is a tool assessing fatigue and exhaustion as the core features of burnout. Despite its wide use and evidence of good psychometric properties, little is known about its structural validity. Therefore, this study aimed to examine internal psychometric properties and the latent composition of the Serbian version of CBI. A sample of 382 child welfare workers engaged in the work with the domestic population and professionals working with refugees and migrants completed a 19-item version of CBIser. Results showed that full-scale CBI despite having good psychometric properties lacks structural validity. A short-form of the instrument was empirically derived and several concurrent confirmatory models found in previous studies were tested. A three-factor model of personal, work-, and client-related burnout showed to be the best fitting one, and the 13-item form of CBI proved to be a structurally valid and psychometrically sound measure of burnout.
