Social support and depressive symptoms among migrant elderly following children: the chain mediating role of resilience and loneliness

Background Migrant elderly following children (MEFC) is an emerging special elderly mobile migrant population in China. MEFC face multiple dilemmas of distress, which makes their depressive symptoms more prominent. To explore ways to alleviate depressive symptoms, this study aimed to investigate the chain mediating effects of resilience and loneliness on the relationship between social support and depressive symptoms among MEFC. Methods A cross-sectional study was conducted using purposive sampling from Changsha, Hunan Province, China, and 298 MEFC were included. The 15-item Geriatric Depression Scale, Social Support Rating Scale, University of California Los Angeles Loneliness Scale, and Connor-Davidson Resilience Scale were used to measure depressive symptoms, social support, loneliness, and resilience, respectively. Pearson's correlation analysis was conducted to clarify the association between the variables. The PROCESS macro model 6 was applied to analyze the multiple mediating effects. Results The prevalence of depressive symptoms among MEFC was 29.86%. Social support (r = -0.354, P < 0.001), resilience (r = -0.373, P < 0.001), and loneliness (r = 0.483, P < 0.001) were significantly associated with depressive symptoms. Social support not only had a direct negative effect (Effect= -0.086, 95% CI: -0.149 to -0.023) on depressive symptoms, but also had an indirect effect on depressive symptoms through resilience (Effect= -0.045, 95% CI: -0.076 to -0.015), loneliness (Effect= -0.053, 95% CI: -0.091 to -0.020), and the chain mediating effects of resilience and loneliness (Effect= -0.019, 95% CI: -0.037 to -0.007), respectively. Conclusions The prevalence of depressive symptoms was relatively high. Resilience and loneliness partially mediated the association between social support and depressive symptoms. In the future, interventions could focus on increasing social support to enhance resilience and reduce loneliness, thereby reducing depressive symptoms in MEFC.
