Results: Post-retirement social relationship changes exhibited significant a positive association with depressive symptoms and loneliness, while social networks demonstrated a significant negative association with depressive symptoms. The older adults experiencing post-retirement social relationship substantial changes were more vulnerable to developing depressive symptoms. Furthermore, loneliness mediated the association between post-retirement social relationship changes and depressive symptoms, whereas social networks moderated this association.

Conclusion: The findings elucidate the association between post-retirement social relationship changes and depressive symptoms among Chinese older adults, highlighting the roles of loneliness and social networks.
