Psychometric properties of the Chinese version of Copenhagen burnout inventory among employees in two companies in Taiwan.

This study examined the psychometric properties of two selected scales--'personal burnout' and 'work-related burnout'--from the Chinese version of the Copenhagen Burnout Inventory (C-CBI) in 384 employees from two companies in Taiwan. A self-administered questionnaire was used that included the two C-CBI scales, the scales of mental health, vitality and general health from the Short Form 36 (SF-36), perceived level of job stress, job satisfaction, working hours, as well as measures for psychological job demands, job control, work-related social support, and over-commitment to work. Both the C-CBI personal burnout scale and work-related burnout scale had high internal consistency and were correlated well with other health, job characteristics, and perception of work measures;furthermore, exploratory factor analysis extracted two empirical factors. However, the two C-CBI scales were highly correlated in the present population and appeared to measure overlapping concepts. Some comments and suggestions were raised for further improvement.
