Psychometric properties of the Vietnamese version of the Copenhagen Burnout Inventory (CBI-V) and its associated factors among community pharmacists in Thua Thien Hue, Vietnam

Abstract

This study evaluates the psychometric properties of the Vietnamese version of the Copenhagen Burnout Inventory (CBI-V) and examines factors associated with burnout among community pharmacists in Thua Thien Hue, Vietnam. A cross-sectional, interview-based study was conducted in Hue City from January to June 2023, involving 362 pharmacists. The following measurement properties of CBI-V were tested: distributional characteristics, structural validity (principal component and confirmatory factor analyses), internal consistency reliability (Cronbach’s alpha and McDonald’s omega), known-groups validity (Mann-Whitney U or Kruskal-Wallis H test). The CBI-V demonstrated good internal consistency, with Cronbach’s α and McDonald’s Omega coefficients ranging from 0.867 to 0.904. The 19-item, three-factor model showed a good fit, supported by Kaiser-Meyer-Olkin measures. CPs working in hospital retail settings, experiencing higher job satisfaction, and having a better grasp of accurate drug information sources were associated with higher burnout scores (p<0.05). This psychometric assessment study in community pharmacists concludes that the CBI-V is a reliable tool for assessing burnout, providing insights for public health interventions in healthcare digital transformation.
