Validation of the Perceived Community Support Questionnaire for Older Chinese.

Background and objectives: Community support has a profound positive impact on older people's health and plays a crucial role in facilitating aging in place. This impact is particularly significant in the Chinese context, where community support can alleviate the pressure on traditional family caregiving. This study translated, adapted, and validated the perceived community support questionnaire (PCSQ) for use with older Chinese.

Research design and methods: Data for this validation study were collected from a cross-sectional survey of 1,064 Chinese aged 65 years and above. Following the cultural adaptation of the PCSQ-14, confirmatory factor analysis (CFA) was conducted to examine its factor structure. Criterion validity, convergent and discriminant validity, internal consistency reliability, and test-retest reliability of the scale were also assessed.

Results: Based on the CFA results, the adapted PCSQ-14 was found to have a 3-factor solution for community integration, community participation, and community organizations. The criterion-related validity was supported by its significant correlation with depression. Convergent and discriminant validity were established, with the internal consistency of the scale being 0.90. The test-retest reliability intraclass correlation coefficient for the scale was 0.78.

Discussion and implications: The adapted version of the PCSQ-14 demonstrated promising psychometric properties in assessing perceived community support in older Chinese. The adapted PCSQ-14 could assist researchers in determining older Chinese adults' perceptions of community support, and could also assist practitioners and policymakers in developing targeted services for older people and allocating resources more effectively.
