Objective To translate and evaluate the validity and reliability of Social Capital Scale for Caregiver of people with Dementia（SCCD）. Methods The Chinese version SCCD was formed through translation, back-translation and cultural adaptation. A total of 221 eligible caregivers of people with dementia were included using convenience sampling method to test the psychometric pro-perties of the Chinese version SCCD. Results The Chinese version SCCD consisted of 15 items after cultural adaptation and item analysis.A total of 3 factors （reciprocity, trust and neighborhood support） were extracted through exploratory factor analysis, collectively explaining 75.668% of the total variance. Criterion-related validity, evaluated by calculating the correlation with the Mutuality Scale, stood at 0.419 （P＜0.05）.The Cronbach′s α coefficient was 0.936 for the scale, and ranged from 0.859 to 0.947 for the three factors. Conclusion The Chinese version SCCD has good reliability and validity, and it can be used as a reliable tool to eva-luate the social capital of family caregivers of people with dementia.
