Although the protective value of social connectedness is emphasized in suicide prevention programming, little is known about the relationship between connectedness in high-risk runaway and homeless youth (RHY) networks and suicidal ideation.
The study examined how social connectedness, in the form of social network position and network exposures, was associated with suicidal ideation among RHY.
Using population-level social network data from 384 RHY, each youth's network position and exposure to potentially suicidogenic peer attributes were calculated. Logistic regression analyses were used to examine associations between network position (core vs. periphery), peer exposures (e.g., depressed or suicidal peers), and suicidal ideation.
In univariable analyses, being in the core of the network and being connected to greater proportions of depressed and suicidal peers increased the likelihood of suicidal ideation. In the final multivariable model, higher exposure to depressed peers remained associated with suicidal ideation, and a marginal effect for network position was observed.
The risk of suicidal ideation was linked to depression among peers and to a lesser extent being more integrated into the RHY network. Identifying and treating depression in naturally occurring friendship groups, particularly in the core of the network, represents a promising network-level intervention.
尽管在自杀预防规划中强调了社会联系的保护价值，但对于高危离家出走和无家可归青少年（RHY）网络中的联系与自杀意念之间的关系却知之甚少。
本研究考察了以社会网络位置和网络接触形式存在的社会联系如何与RHY中的自杀意念相关联。
利用来自384名RHY的人群水平社会网络数据，计算了每个青少年的网络位置以及接触潜在自杀倾向同伴特征的情况。采用逻辑回归分析来检验网络位置（核心与边缘）、同伴接触（如抑郁或有自杀倾向的同伴）与自杀意念之间的关联。
在单变量分析中，处于网络核心以及与更大比例的抑郁和有自杀倾向的同伴建立联系会增加自杀意念的可能性。在最终的多变量模型中，更高程度地接触抑郁同伴仍然与自杀意念相关，并且观察到网络位置的边际效应。
自杀意念的风险与同伴中的抑郁有关，并且在较小程度上与更多地融入RHY网络有关。在自然形成的友谊群体中，特别是在网络核心识别和治疗抑郁，是一种有前景的网络层面干预措施。
