Social capital is associated with depression independently of individual-level risk factors. We used a sample of 1586 same-sex twin pairs to test the association between seven measures of social capital and two related measures of neighborhood characteristics with depressive symptoms accounting for uncontrolled selection factors (i.e., genetics and shared environment). All measures of cognitive social capital and neighborhood characteristics were associated with less depressive symptoms in between-twin analysis. However, only measures of cognitive social capital were significantly associated with less depressive symptoms within-pairs. These results demonstrate that cognitive social capital is associated with depressive symptoms free of confounding from genetic and environmental factors shared within twins.
社会资本与抑郁症相关，且独立于个体层面的风险因素。我们使用了1586对同性双胞胎样本，来检验七种社会资本测量指标与两种邻里特征相关测量指标之间的关联，同时考虑未控制的选择因素（即遗传学和共享环境）对抑郁症状的影响。在双胞胎间分析中，所有认知社会资本和邻里特征测量指标都与较少的抑郁症状相关。然而，仅认知社会资本测量指标在双胞胎对内与较少的抑郁症状显著相关。这些结果表明，认知社会资本与抑郁症状相关，且不受双胞胎内部共享的遗传和环境因素的混杂影响。
