Objectives： In spite of many studies regarding the occupational functioning of persons with mental illness, there are lack of tools to evaluate it properly. The Wok Behavior Inventory(WBI) is a standardized work performance assessment instrument specifically designed for persons with severe mental illness. The purpose of this study was to examine the reliability and validity of the Korean version of WBI.
Methods：The subjects were 158 members in community mental health center around Seoul City and Kyonggi Province. KWBI consists of 26 items with subscale of cooperativeness, work habits, work quality, social skills, and personal presentation. Evaluation was done by the fifteen minutes observation of workers behavior in the job site and discussion with job supervisor.
Results： Reliabilities of individual items, scales, and inventory total are in the good to excellent range. The internal consistency coefficients(Cronbach alpha) of each subscale ranged from .88 to .95. The validity of the KWBI was investigated by principal component analysis, yielding 5 factors of social skill, cooperativeness, work habit and attitude, work quality, and self presentation.
Conclusion： Overall, the findings support the utility of KWBI as a tool to evaluate work related behavior in vocational rehabilitation for the chronic mentally ill patients.
