Abstract
Burnout is a widespread occupational phenomenon with adverse effects on the well-being and performance of healthcare professionals. In Latvia, the lack of a psychometrically validated instrument for measuring burnout has hindered effective assessment and intervention. This study aimed to adapt the Copenhagen Burnout Inventory (CBI) for use in the Latvian context and to evaluate its psychometric properties among healthcare workers. A cross-sectional study was conducted in Latvia with a total of 288 participants from various healthcare institutions. The adaptation process included forward translation, expert panel review, and face validity testing. The initial item pool comprised 19 items reflecting three subscales: personal burnout (PB), work-related burnout (WB), and client-related burnout (CB). Reliability was assessed using Cronbach's alpha, composite reliability (CR), and average variance extracted (AVE). The final model showed strong internal consistency (α > 0.80), acceptable construct validity (CR > 0.80; AVE > 0.50), and a good model fit (χ(2)/df = 2.6; RMSEA = 0.06; CFI = 0.95; TLI =0.94). The findings demonstrate that the Latvian version of the CBI is a valid and reliable tool for assessing burnout among healthcare professionals. This study represents the first full adaptation and validation of the CBI in Latvia and provides a foundation for future research and practical applications in occupational health monitoring and burnout prevention.
