Abstract: The Workshop Behavior Checklist is a standardized assessment instrument to assess the work performance of people with severe mental illness using the situational assessment approach. It is modified from the Behavior Identification Form developed by the Material Development Center. The modification process was conducted by enlisting input from mental health professionals ( n = 150) and potential employers of discharged patients with mental illness ( n = 31) by ques tionnaires specially designed for this purpose. The results of these questionnaires were then analyzed by an expert panel consisting of 10 therapists and one psychiatrist working in relevant fields. Altogether 14 items in general behaviors, vocational behaviors, and social behaviors were selected. In addition, a new version of the checklist together with its rating guidelines were designed. Explora tory factor analysis (n = 112) shows that all 14 items fit well into a four-factor model explaining 67.2% of total variance, which is in line with the original design of the revised checklist. Cronbach alpha analysis shows that the revised checklist has acceptable to very good internal consistency (.51 to .84) and intraclass correlation coefficients indicate that it has good to excellent inter-rater (.57 to .81) and test-retest (.86 to .94) reliability. Clinical implications and further research are discussed.
