Outline
To explore the mediating role of social activity in the relationship between community environment and loneliness.
Convenience sampling was used to select 324 community-dwelling older adults in Guiyang City as study participants between February and July 2025. Data collection tools included a general information questionnaire, the DJGLS Loneliness Scale, the Community Social Environment Perception Evaluation Questionnaire, and the Community Built Environment Perception Evaluation Questionnaire. Mediation effect analysis was conducted using Model 4 in the SPSS PROCESS macro program.
Spearman correlation analysis showed that community social environment(r= -0.560, P<0.001).community built environment (r=-0.605, P<0.001) and social activity (r= -0.627, P<0.001) were negatively correlated with loneliness; Social activity was positively correlated with community social environment (r=0.441, P<0.001) and community built environment (r= 0.472, P<0.001). The results of the mediation effect test showed that social activity partially mediated the relationship between community social environment, community-built environment, and loneliness, with mediation effects accounting for 29.29% and 25.18%, respectively.
Community environment not only directly influences older adults’loneliness but also indirectly influences it through social activity. Efforts should be accelerated to build elderly-friendly community environments, organize elderly activities based on communities, enhance older adults’social activity, and reduce the incidence of loneliness.
