这项短期前瞻性研究在一个不同种族的LGBT青年样本（N = 237，47.7%为男性）中检查了自杀企图的一般和女同性恋、男同性恋、双性恋和变性者（LGBT）特异性风险和保护因素。一个结构化的精神病学访谈评估了临床抑郁症和行为障碍症状，以及过去和未来的自杀企图超过1年的随访期（91%的保留）。参与者完成了问卷调查，测量自杀企图的一般风险因素，包括绝望，冲动和感知的社会支持。他们还完成了LGBT特定自杀风险因素的测量，包括性别不一致，第一次同性吸引的年龄和LGBT受害。相关分析和多元回归分析，以检查预测因素和自杀企图之间的关系，并确定中介。在九个变量中，有七个与自杀未遂的终身史有关：绝望，抑郁症状，行为障碍症状，冲动，受害，第一次同性吸引的年龄和低家庭支持。抑郁症状和绝望介导了多种风险和弹性因素与自杀企图之间的关系。自杀未遂史是预测未来自杀未遂的最强预测因子。在1年的随访期内，曾试图自杀的参与者（占样本的31.6%）再次尝试自杀的几率比那些从未尝试过自杀的人高出10倍以上。这些结果强调了LGBT青年自杀预防计划的必要性，并表明解决抑郁和绝望作为近端决定因素以及家庭支持和受害的重要性，这具有更远的影响。
This short-term prospective study examined general and lesbian, gay, bisexual, and transgender (LGBT)-specific risk and protective factors for suicide attempts in an ethnically diverse sample of LGBT youth (N = 237, 47.7 % male). A structured psychiatric interview assessed clinical depression and conduct disorder symptoms, as well as past and prospective suicide attempts over a 1-year follow-up period (91 % retention). Participants completed questionnaires measuring general risk factors for suicide attempts, including hopelessness, impulsiveness, and perceived social support. They also completed measures of LGBT-specific suicide risk factors, including gender nonconformity, age of first same-sex attraction, and LGBT victimization. Correlation and multivariate regression analyses were conducted to examine the relations between predictors and suicide attempt, and to identify mediators. Of nine variables examined, seven were related to lifetime history of attempted suicide: hopelessness, depression symptoms, conduct disorder symptoms, impulsivity, victimization, age of first same-sex attraction, and low family support. Depressive symptoms and hopelessness mediated the relation between multiple risk and resilience factors and suicide attempts. Suicide attempt history was the strongest predictor of prospective suicide attempts. Participants who previously attempted suicide (31.6 % of the sample) had more than 10 times greater odds of making another attempt in the 1-year follow-up period than were those who had made no previous attempt. These results highlight the need for suicide prevention programs for LGBT youth and suggest the importance of addressing depression and hopelessness as proximal determinants and family support and victimization, which have more distal effects.
