Abstract: Impairment of social functioning in persons with schizophrenia restricts their quality of life and reduces their community tenure. Enhancement of social functioning is an important goal and outcome measurement of occupational therapy services. The purpose of this study is to validate the Individuals' version and Relatives' version of the Chinese SFS and studying their psychometric properties for persons with schizophrenia in Hong Kong. The study was consisted of three stages: 1) to translate the SFS into Chinese; 2) to evaluate its content validity of the Chinese SFS, which include the cultural relevance and representativeness of items and subscales by eight multi-disciplines experts; and 3) to conduct the convergent validity and reliability study. In panel review of content validity, most of the subscales were regarded as culturally relevant. Some members expressed reservation on the relevance of some items in recreation and prosocial activity subscale. Item modifications were made mainly on these subscales and the final Chinese version has a total of sixty-two items. In the convergence validity and reliability study, a total of 61 persons with schizophrenia and 17 caregivers were recruited. There was low but significant correlation between the total score of Individuals' version and Social and Occupational Functioning Assessment Scale, SOFAS (r=0.39) and moderate correlation between Relatives' version and SOFAS (r=0.57). The internal consistency in both the Individuals' version and Relatives' version were fair to good across subscales ('帢 individual 0.39 -0.82 & '帢 relative 0.42 -0.81). The test-retest reliability study of Chinese SFS measurement was good to excellent (ICC=0.76 - 0.99). In comparison of ratings from persons with schizophrenia and their caregivers, there were differences in perception in performance of the persons, particularly in the Independence-competence subscale. In conclusion, the reliability of Chinese SFS needed further study to clarify the evidence for internal consistency and its self-reported data collection.
