Suicide is a problem of worldwide concern and research on possible protective factors is needed. We explored the role of social support as one such factor. Specifically, we hypothesized that increased social support would be associated with decreased likelihood of a lifetime suicide attempt in two nationally representative samples as well as a high-risk subsample.
We analyzed the relationship between social support and lifetime history of a suicide attempt, controlling for a variety of related psychopathology and demographic variables, in the National Comorbidity Study Replication (NCS-R), a United States sample and the Adult Psychiatric Morbidity Study (APMS), an English sample.
Results indicate that social support is associated with decreased likelihood of a lifetime suicide attempt controlling for a variety of related predictors in both the full US sample (OR=0.68, p<.001) and the full English sample (OR=0.93, p<.01).
The cross-sectional data do not allow true cause and effect analyses.
Our findings suggest social support is associated with decreased likelihood of a lifetime suicide attempt. Social support is a highly modifiable factor that can be used to improve existing suicide prevention programs worldwide.
自杀是一个全球性关注的问题，需要研究可能的保护因素。我们探讨了社会支持作为其中一个因素的作用。具体来说，我们假设在两个具有全国代表性的样本以及一个高风险亚样本中，社会支持的增加与自杀未遂的可能性降低有关。
我们分析了社会支持与自杀未遂的终生史之间的关系，在国家共病研究复制（NCS-R）中，我们控制了多种相关的精神病理学和人口统计学变量，这是一个美国样本，以及成人精神病理学研究（APMS），这是一个英国样本。
结果表明，在控制了全美国样本（OR=0.68，p<.001）和全英国样本（OR=0.93，p<.01）中多种相关预测因素后，社会支持与自杀未遂的可能性降低有关。
横断面数据不允许进行真正的因果分析。
我们的发现表明，社会支持与自杀未遂的可能性降低有关。社会支持是一个高度可改变的因素，可以用来改善全球现有的自杀预防计划。
