Examining the psychometric properties of the Maslach Burnout Inventory with a sample of child protective service workers in Korea

Abstract

This study evaluated the psychometric properties of a revised Maslach Burnout Inventory (MBI) for child protective service (CPS) workers. The psychometric properties of this revised measure were verified using item analyses, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). For cross-validity, a total of 249 CPS workers in South Korea were randomly divided into two groups: one group for the EFA ( n = 124/249) and the other group for the CFA ( n = 125/249). The final version of the 15-item MBI showed a good internal consistency. In addition, a CFA verified the acceptability of the model fit. The results confirmed that the 15-item revised MBI was both reliable and valid. In conclusion, the MBI currently used for CPS workers may also be useful in clinical and research settings.
