RESUMO
Objective:To explore the psychometric characteristics of the Chinese version of the health-related social capital scale.Methods:From March to May 2020, after the original scale was translated into Chinese following the Brislin improved translation model, 251 community-dwelling senior citizens aged 65 and above were selected by convenient sampling method. Data analysis was conducted using SPSS 22.0 and AMOS 22.0, including tests of significance, correlation analysis, exploratory factor analysis, and confirmatory factor analysis.Results:Exploratory factor analysis extracted three factors: social participation, social cohesion, and reciprocity, which accounted for a cumulative contribution rate of 61.72%. Confirmatory factor analysis showed that the three-factor model fitted well(χ 2/ df=1.22, RMSEA=0.04, CFI=0.98, GFI=0.93, IFI=0.98, TLI=0.97). Social capital was significantly correlated with perceived social support positively ( r=0.36, P<0.01), and with loneliness negatively ( r=-0.30, P<0.01). The three factors were significantly correlated with the total scale ( r=0.85, 0.50 and 0.52, respectively, all P<0.01). And correlations between the items of each factor were 0.24-0.55, 0.30-0.59, 0.44-0.70, respectively(all P<0.01). The Cronbach's α coefficients of the total scale and three factors were 0.74, 0.72, 0.65 and 0.62, respectively(all P<0.01), and their retest reliability were 0. 92, 0. 87, 0. 82 and 0. 96, respectively(all P<0.01). Conclusion:The Chinese version of health-related social capital scale conforms to the three-factor model with good reliability and validity, which can be used to assess the social capital status of community-dwelling older adults in China.
