Disability, Psychological Well-Being, and Social Interaction in Later Life in China.

Many studies show that disability predicts lower social participation and poorer psychological well-being. However, few have examined how disability, social interaction, and psychological well-being interrelate with one another. We use diary data from World Health Organization's Study on Global AGEing and Adult Health, 2007-2010 ( N = 8,771) and mediation analysis to examine the links between disability, daily social interaction, and the momentary and global well-being of older adults in China. We find suggestive support for the hypothesis that psychological well-being predicts social interaction in the context of disablement, but little evidence for the converse. Specifically, in a cross-sectional analysis, disability predicts lower levels of momentary affect, happiness, and life satisfaction, which are linked to spending more time alone and participating in fewer activities with grandchildren, friends, and coworkers. These findings are consistent with the hypothesis that a less active social life is explained by poor functional performance and compromised psychological vibrancy.
