The impact of poverty alleviation through relocation on loneliness among older adults: the mediating role of social networks and the moderating role of support policies

This study reveals that while PAR improves material conditions, it may simultaneously create structural risks for the psychological well-being of older adults by disrupting social networks and weakening emotional support. The study recommends building differentiated psychological support systems, strengthening mechanisms for social network reconstruction, improving targeted support for vulnerable groups, and integrating mental health services into community governance. These measures can systematically enhance the psychological well-being of older adults in PAR communities.
