Validity and Reliability of Persian Version of Social Capital Tool: A Sample of Iranian Older People

Background: Social capital and social participation has a significant role in improving the health of the older adults. The current study aimed to examine the psychometric properties of the Persian version of the Adapted Social Capital Assessment Tool (SASCAT) in the older adults.Methods: A total of ۴۱۴ community-dwelling older people (aged ۶۰ years or older) in Aran and Bidgol city selected through multistage cluster sampling method. Construct validity evaluated by exploratory and confirmatory factor analyses. Reliability of the tool was assessed using Cronbach’s alpha and interclass correlation coefficient. The Pearson correlation coefficient test was used to evaluate the convergent validity of the instrument between WHO-۵ and SASCAT. SPSS۲۴ and AMOS۲۴ software were used for statistical analysis.Results: The three factors of received social support, social participation, and social trust were extracted from exploratory factor analysis, which explained ۶۶.۳۳% of the total variance. The CFA revealed that the SASCAT structure model was a validated model (CMIN/DF=۲.۳۶, GFI=۰.۹۵۷, CFI=۰.۹۳۱, RMSEA=۰.۰۸۱). There was a significant positive relationship between social capital and psychological wellbeing (r=۰.۲۸, p< ۰.۰۱), according to the results of the convergent validity evaluation. Moreover, the Persian version of social capital tool had acceptable internal consistency and test-retest reliability.Conclusions: The ۸-item social capital tool is a valid and reliable measurement tool that can be used in future studies to examine the status of this concept among Iranian older people.
