Abstract: This study aims to investigate the reliability and validity of the Chinese version Work Personality Profile (CV-WPP) in assessing employability of psychiatric day patients in Hong Kong. Eight psychiatric day-hospital patients were assessed successively with the two language versions of Work Personality Profile (WPP) to reveal the equivalence of the ratings of the source (English) and target (Chinese) language versions of WPP. Twenty rehabilitation professionals with extensive experience in vocational rehabilitation of people with psychiatric illness were recruited from work rehabilitation institutions to form an expert panel for gathering evidence on the content validity of the Profile. To estimate the reliability of the CV-WPP, one hundred and sixteen day-hospital patients were assessed by six practising occupational therapists in two psychiatric day hospitals. Test-retest reliability on the CV-WPP was estimated by the intra-class correlation coefficient (ICC) and Pearson's Product-moment Correlation. Satisfactory correlation coefficients were obtained, ranging from .83 to .97 and .80 to .96 for rational subscales and .83 to .92 and .86 to .91 for factor analytical subscales respectively. Inter-rater reliability of the subscales of CV- WPP was similar to that of the original WPP, ICC ranges from .55 to .79 for rational subscales and .83 to .93 for factor analytical subscales. Three rational subscales gave relatively low correlation coefficients. The relatively low coefficient reflected the subjective components of the direct observation approach in employment assessment. Internal consistency of the subscales were estimated by computing Cronbach's alpha on the subscale ratings. Satisfactory alpha values on the rational subscales ( .62 to .92 ) and the factor analytical subscales ( .81 to .97 ) resulted. Item analysis on the fifty-eight items revealed fair item-scale correlations on five of the CV-WPP items. In computing the t-values of the two language versions of WPP, no significant difference was noted on the subscale ratings of the two language versions of WPP. The conceptual and sementic equivalence of CV-WPP was ensured. Content validation revealed the comprehensiveness and adequacy of the subscales and items of CV-WPP in assessing employability of psychiatric day-hospital patients locally. Ratings on the relevancy of individual items indicated eight items as fair in relevancy to the individual subscales. Three items were commented on as moderate in relevancy in the item content and further revision was recommended. Expert members further recommended simplifying the eleven rational subscales by combining four pairs of the subscales. This study facilitated the further validation and revision of the Profile on convergent, discriminant concurrent validation and predictive validation to legitimise the Profile in local practice.
