This study describes the construction of the Chinese version of the Social and Communities Opportunities Profile (SCOPE), henceforth, the SCOPE-C, to measure social inclusion among mental health services users in Hong Kong. The SCOPE-C was developed based on concept-mapping and benchmarking of census questions. The questionnaire consisted of 56 items, went through a standardized linguistic validation process and was pilot tested with qualitative feedback from five users of mental health services. Altogether 168 Chinese service users were recruited through various NGO mental health services to have three times face-to-face interview between October 2013 and July 2014. Results indicated that items related to satisfaction with opportunities and perceived opportunities in various social domains had high consistency. Nearly all the Kappa statistics and Pearson correlation coefficients between the baseline and two rounds of re-test were significant. The SCOPE-C was considered a valid instrument for Hong Kong mental health user population.
