OBJECTIVES: Although previous studies have examined the psychological benefits of physical activity in cancer survivors, the underlying psychological mechanisms among lung cancer survivors remain poorly understood. This study aims to examine the parallel mediating roles of social connection and self-efficacy in stress coping in the association between physical activity and psychological distress (anxiety and depression) among Chinese lung cancer survivors. DESIGN: A cross-sectional observational study. SETTING: A tertiary care hospital in Shanghai, China. PARTICIPANTS: A total of 588 lung cancer survivors were recruited and assessed physical activity, anxiety, depression, social connection and self-efficacy in stress coping.

RESULTS: Social connection (p=0.003 for anxiety; p<0.001 for depression) and self-efficacy in stress coping (p<0.001 for anxiety; p<0.001 for depression) significantly mediated the association between physical activity and psychological distress. Physical activity was positively associated with so...
