Objective: To assess the accuracy of translated instructions, items, content relevance, test-retest reliability and interrater reliability of the Chinese version of three selected modules of the VALPAR Pro3000 Modular Assessment System for assessing persons with mental illness: (1) computerised assessment (COMPASS); (2) Physical, Environmental and Temperaments (PET) survey; and (3) spatial aptitude/nonverbal reasoning. Methods: An expert panel of 12 experienced occupational therapists evaluated the translation and content validity. Twenty-nine participants completed all of the selected modules twice during a 10-day interval to assess the test-retest reliability. To assess interrater reliability, two raters assessed the COMPASS work-sample tests taken by another 30 participants. Results: Most of the COMPASS subtests had moderate to good retest reliability. The PET survey and spatial aptitude/nonverbal reasoning modules showed good retest reliability. Interrater reliability of the work samples was good. Conclusion: The results of this study provide preliminary support for the reliability of the selected Pro3000 system modules in evaluating the work capabilities of people with mental illness.
