Validation of the <i>Study Burnout Inventory</i> and the <i>Copenhagen Burnout Inventory</i> for the use among medical students

Abstract

tors associated with, burnout among medical students can help develop evidence-based programs for the prevention of burnout The most commonly used questionnaire on burnout was developed by Maslach and it measures burnout in 3 dimensions: emotional exhaustion, depersonalization and a lack of personal accomplishment The main constraint as to the use of the Maslach Burnout Inventory (MBI) is that it was intended for the use among service professionals. Consequently, the Danish National Institute of Occupational Health developed the Copenhagen Burnout Inventory (CBI) with the aim of measuring burnout in different settings The concept behind the development of CBI was that burnout syndrome is not only associated with emotional exhaustion, but also with physical exhaustion, which develops in the personal sphere, the work sphere and in interactions with clients This concept has led to the development of 3 subscales of CBI (personal burnout, workrelated burnout and client-related burnout) While CBI can be used in different settings, including the student population, it was not specifically developed for students. The instruments for assessment purposes need to be reliable, but should also be especially adapted for the student population. Therefore, the Study Burnout Inventory (SBI) was developed based on the School Burnout Inventory and the Work Burnout Inventory [3], showing good reliability. To the best of the authors' knowledge, although studies regarding burnout syndrome were previously conducted in Serbia, MBI was most commonly used as the instrument Abstract Objectives: The aim of this study was to assess the validity and reliability of the Serbian versions of the Copenhagen Burnout Inventory (CBI) and the Study Burnout Inventory (SBI) among fifth-year medical students at 5 universities in Serbia. Material and Methods: The study included 573 fifthyear medical students at 5 universities in Serbia. The research instrument consisted of SBI and CBI. The reliability of these instruments was assessed using an internal consistency measure (Cronbach's ), an intra-class coefficient (ICC) and factor analysis. Results: Cronbach's for SBI was 0.83, including for exhaustion 0.73, for cynicism 0.70, and for inadequacy 0.48. The test-retest reliability (ICC) was 0.75. Cronbach's for personal burnout on CBI was 0.89, for the faculty-related burnout 0.86, and for the faculty-members-related burnout 0.92. Cronbach's for CBI was 0.93. The factor analysis for SBI showed 2 factors and for CBI 3 factors. Conclusions: This study revealed that the Serbian versions of both SBI and CBI could be used for the assessment of burnout in this population.
