[Mediation role of self-efficacy between social support and depression of only-child-lost people].

ABSTRACT

OBJECTIVE: To investigate the relationship between social support and depression of only-child-lost (OCL) people, and the mediation role of self-efficacy in this relationship. 
 Methods: By stratified cluster sampling, 214 OCL people were enrolled, with 80 males and 134 females, ages from 49 to 83 years old. They were assessed by General Self-Efficacy Scale, Social Support Rating Scale, and Self-rating Depression Scale.
 Results: Univariate analysis showed that there were significant differences in age groups (t=2.85, P<0.05), with or without spouse (t=5.62, P<0.05), family location (t=3.95, P<0.05), per capita monthly income (F=3.48, P<0.05) among the social support scores. There was significant difference between the per capita monthly income and self-efficacy scores in QCL people (F=5.46, P<0.05). Correlation analysis showed self-efficacy and social support were positively correlated (r=0.26, P<0.01). Self-efficacy (r=-0.59, P<0.01) and social support (r=-0.59, P<0.01) negatively correlated with depression in OCL people. Self-efficacy partially mediated the relationship between social support and depression.
 Conclusion: The person who is <60 years old, with spouse and the high per capita monthly income, and lives the rural area, would have high social support levels among QCL people. The person who has high per capita monthly income would have high self-efficacy. Self-efficacy is one of the direct prediction for depression, and plays an indirect role between social support and depression. Intervention of depression among OCL people could be applied to change their cognition, and to enhance their self-efficacy.
