Objectives: The study aimed to present the Polish version of the Burnout Assessment Tool (BAT-PL) by W. Schaufeli et al. and to assess its validity and reliability. The tool measures the core symptoms of burnout (BAT-C): exhaustion, mental distance, cognitive and emotional impairment, and its secondary symptoms (BAT-S): psychosomatic complaints and psychological distress.
Methods: The participants were 255 nursing staff members. The construct validity was assessed with a one-point job satisfaction scale, the Utrecht Work Engagement Scale by Schaufeli et al. and the Job-related Affective Well-being Scale by van Katwyk et al.
Results: The results of the confirmatory factor analysis supported an assumed bi-factor structure. This applies to both BAT-C as the four core symptoms and a general factor and BAT-S as a set of two secondary symptoms and a general factor. Both scales were strongly correlated with one another and differed from other measures of job-related well-being (job satisfaction, work engagement and negative emotions). The values of Cronbach's alpha and composite reliability indicated BAT-PL as a reliable measurement tool.
Conclusions: BAT-PL by W. Schaufeli et al. has good psychometric characteristics to be used in research on burnout and further validated in clinical practice.
