This study assessed genetic and environmental influences on the association between social support and psychological functioning using the combined adoption/twin design from the Swedish Adoption/Twin Study of Aging. A subsample of 424 twin pairs, 50 years and older, was used: 64 pairs of identical twins reared apart, 95 pairs of identical twins reared together, 132 pairs of fraternal twins reared apart, and 133 pairs of fraternal twins reared together. Multivariate model-fitting analyses indicated that the relationship between the perceived adequacy of social support and psychological well-being (depression and life satisfaction) was mediated in part by genetic factors.
本研究采用瑞典老年收养/双胞胎研究中的收养/双胞胎联合设计，评估了社会支持与心理功能之间关联的遗传和环境影响。使用了一个由424对50岁及以上双胞胎组成的子样本：64对分开抚养的同卵双胞胎、95对一起抚养的同卵双胞胎、132对分开抚养的异卵双胞胎和133对一起抚养的异卵双胞胎。多变量模型拟合分析表明，社会支持感知充足度与心理健康（抑郁和生活满意度）之间的关系部分由遗传因素介导。
