Evaluation of the psychometric properties of the Copenhagen burnout inventory–student survey (CBI-SS) among health profession educational students at a university in south India

Background & Objective: Burnout is characterized by emotional exhaustion and affects diverse professionals, with healthcare students at high risk due to academic and clinical stressors.The Copenhagen Burnout Inventory-Student Survey (CBI-SS) has not been studied in healthcare students in the Indian context.This study aims to evaluate the psychometric properties of the English version of the CBI-SS. Material & Methods:This cross-sectional study, conducted in 2022, included 416 undergraduate and 107 postgraduate students from health profession institutions at a private university.The response rate was 65.45%.Descriptive and inferential statistics were evaluated for the CBI-SS with 25 items via JMP software.The tool was subjected to content and face validity.The interitem correlation was tested before the scale was subjected to Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA).The EFA indices considered were Kaiser-Meyer-Olkin test (KMO) and the Bartlett test of specificity.The CFA fit indices included the degree of freedom, Tucker Lewis index (TLI), freedom ratio (/df), Goodness-of-Fit Index (GFI), Comparative Fit Index (CFI), Root Mean Square Error Of Approximation (RMSEA), and Normed Fit Index (NFI). Results:The content validity index averaged 0.9, and face validity was favorable.The Cronbach's alpha scores were between 0.7 and 0.8.The EFA yielded KMO values above 0.9, and Bartlett's test yielded chi-square = 8880.727,df = 300, p < 0.0001.The fit indices for CFA were the Tucker and Lewis indices, with a score of 0.919 and an RMSEA score of 0.068, demonstrating a relationship between the items and the constructs. Conclusion:This study highlights the usefulness of the CBI-SS in assessing burnout in allied health science and dental student populations.The results indicate that the CBI-SS is a reliable and valid instrument for identifying student burnout and developing strategies to prevent burnout among potentially vulnerable student populations in the Indian context.
