Social Capital and Depression Among Adolescents Relocated for Poverty Alleviation: The Mediating Effect of Life Satisfaction

Background: China’s relocated for poverty alleviation policy has played a pivotal role in eradicating extreme poverty nationwide. However, adolescents relocating with their parents may face multifaceted challenges, including abrupt shifts in their living environments, the reconstruction of social capital, and the psychological turbulence inherent to adolescence. Objectives: We aimed to explore predictors of reducing depressive symptoms in relocated adolescents. We analyzed the associations between social capital, life satisfaction, and adolescent depression. Methods: This study investigated 631 adolescents aged 10–19 years from 24 relocation for poverty alleviation resettlement sites in Shanxi Province. Respondents completed basic demographic information and questionnaires on adolescent social capital, life satisfaction, and depressive symptoms. The mediating role of life satisfaction was assessed using PROCESS 3.4 analysis. Results: The mean social capital score of the adolescents was 31.96 ± 3.666, the mean life satisfaction score was 23.21 ± 6.282, the mean depression score was 4.03 ± 5.503, and the depression detection rate was 15.2%. We found that social capital was significantly positively correlated with life satisfaction (r = 0.363, p ˂ 0.05), both social capital and life satisfaction were negatively correlated with depressive symptoms (r = −0.362, p ˂ 0.05; r = −0.398, p ˂ 0.05), and life satisfaction partially mediated the association between social capital and depressive symptoms (mediating effect of 18.20%). Conclusions: Adolescents in communities relocated for poverty alleviation are overall satisfied with their lives, but some are experiencing some form of depression. Both social capital and life satisfaction are associated with lower depression levels, and those with higher life satisfaction are better able to cope with the changes in social capital associated with environmental changes after relocation, thus helping to reduce depressive symptoms.
