Previous studies have demonstrated positive associations between identity disturbances and suicidality in adolescents; however, mechanisms underlying these relationships are not well understood. The authors propose that borderline features and various internalizing disorders may mediate these relations. The aim of this study was to test a multiple mediation model of the associations between these constructs using structural equation modeling. Ninety-six inpatient adolescents aged 12-17 years completed the Assessment of Identity Development in Adolescents, the Childhood Interview for DSM-IV Borderline Personality Disorder, the Youth Self-Report, and the Columbia-Suicide Severity Rating Scale. Findings partly confirmed the theoretical model. Borderline features mediated the positive effect of identity disturbances on suicidal ideation severity. Mediations of withdrawn/depression and anxiety/depression on the effect of identity disruption on suicidal ideation intensity were demonstrated. Identity disruptions and borderline and depressive symptoms could be possible targets for interventions for youth experiencing suicidal ideation.

住院青少年身份障碍，边界特征，内在障碍和自杀倾向之间的关系。

先前的研究表明，青少年身份认同与自杀倾向之间存在正相关关系。但是，对这些关系的潜在机制还没有很好的理解。作者提出，边界特征和各种内在失调可能介导这些关系。这项研究的目的是使用结构方程模型来测试这些构造之间的关联的多重中介模型。96名12-17岁的住院青少年完成了对青少年身份发展的评估，DSM-IV边缘人格障碍的儿童访谈，青年自我报告以及哥伦比亚自杀严重性等级量表。研究结果部分证实了理论模型。边界特征介导了身份障碍对自杀意念严重性的积极影响。证明了撤消/抑郁和焦虑/抑郁对身份破坏对自杀意念强度的影响。身份中断，边界和抑郁症状可能是干预发生自杀念头的青年的目标。
