Abstract:Based on the data of 2018 China Health and Retirement Longitudinal Study(CHARLS),the
study used linear regression model,stepwise regression and product of coefficients approach to analyze the
influence of volunteer activity participation on life satisfaction and the mediating role of depression. Moreover,
the age⁃group differences in the mechanism were further explored. The findings revealed that volunteer activity
participation was both directly and indirectly associated with life satisfaction among middle⁃aged and elderly
people(β=0.041,P<0.05). Depression was found to mediate the relationship of volunteer participation to life
satisfaction,and the mediating effect accounted for 22.75% . Furthermore,the influence coefficient and
mechanism of volunteer activity participation on different age groups were obviously different. The results had
important values for preventing and intervening depression,improving the mental health and life satisfaction
among middle⁃aged and elderly people,and promoting active aging.
Key words:volunteer activity participation;middle⁃aged and elderly people;life satisfaction;depression
