Research suggests that exposure to adversity can lead to an increased risk of experiencing suicidal and self-injurious thoughts or behaviours, but few studies have examined whether different patterns of adversity are differentially associated with youth suicide/self-harm. The current study aims to explore the relationship between exposure to adversity across various social domains and youth self-harm and suicidality, using a person centred approach, and examines whether access to social support and a sense of safety across home, peer or school settings buffer the relationship between adversity and self-harm/suicidality. Secondary data analyses were carried out on cross-sectional self-report data collected from 4848 (M_age=15.78, SD = 0.59; 50% female) adolescents who participated in the Irish Planet Youth survey. Latent Class Analyses identified four distinct profiles of adversity; low-adversity (n = 2043, 42%); peer-adversity (n = 972, 20%); parental-adversity (n = 1189, 25%); and multiple-adversity (n = 644, 13%). Findings from logistic moderated regressions indicated that there were significant differences in self-harm and suicidality across the adversity classes. Although parental support and perceived safety at school were negatively associated with suicidality and self-harm outcomes, no significant moderation effects were observed. These findings suggest that youth who experience adversity across multiple social domains are more likely to report suicidal and self-harm thoughts and behaviours, and should be key targets for intervention/prevention efforts. While parental support and school safety may act as significant compensatory factors, further work is needed to identify the social resources that can offset the risk imposed by youth’s adverse experiences.

研究表明，暴露于逆境会导致出现自杀和自残想法或行为的风险增加，但很少有研究检查不同的逆境模式是否与青少年自杀/自残有不同的关联。目前的研究旨在探索暴露于不同社会领域的逆境与青少年自残和自杀之间的关系，使用以人为本的方法，并检查在家庭、同伴或学校环境中获得社会支持和安全感是否缓冲逆境与自残/自杀之间的关系。_{对从 4848（M年龄）}收集的横断面自我报告数据进行了二次数据分析=15.78，标准差 = 0.59；50% 的女性）青少年参加了爱尔兰星球青年调查。潜在类别分析确定了四种不同的逆境特征；低逆境（n  = 2043, 42%）；同伴逆境（n  = 972, 20%）；父母逆境（n  = 1189, 25%）；和多重逆境（n = 644, 13%)。逻辑调节回归的结果表明，不同逆境类别的自残和自杀倾向存在显着差异。尽管父母支持和在学校的安全感与自杀和自残结果呈负相关，但未观察到显着的调节作用。这些研究结果表明，在多个社会领域经历逆境的年轻人更有可能报告自杀和自残的想法和行为，并且应该成为干预/预防工作的关键目标。虽然父母的支持和学校安全可能是重要的补偿因素，但还需要进一步的工作来确定可以抵消青少年不良经历带来的风险的社会资源。
