Impacts of psychological resources, social network support and community support on social participation of older adults in China: Variations by different health-risk groups.

Social participation comprises comprehensive interactions between individual health and relevant environmental characteristics, which play an increasingly important role in promoting older adults' health and quality of life. Although many studies have examined impacts of various factors on the social participation of older adults, some internal mechanisms between health characteristics and environmental characteristics have not been revealed. This study aimed to examine the moderating effects of health characteristics on the relationships among psychological resources, social network support, community support and social participation of Chinese older adults. Based on some key health indicators, this study used the two-step cluster algorithm to divide the participants aged over 60 years from the Chinese Longitudinal Aging Social Survey in 2016 (N = 8669) into low (47.2%), moderate (33.8%) and high (18%) health risk groups. A multiple-group structural equation model was then built to examine the effects of psychological resources, social network support and community support on social participation across the three groups. The results suggested that with the increase in health risks, the contributions of psychological resources and community support to social participation decreased from 28.6% to 23.7% and from 61.5% to 50.7%, respectively, while that of social network support increased from 9.9% to 25.6%. These variations suggest that individual health has a significant moderating effect on the psychological and social compensating mechanisms of the social participation among Chinese older adults.
