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 Mediations of withdrawn/depression and anxiety/depression on the effect of identity disruption on suicidal ideation intensity were demonstrated.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、边缘特征、内化障碍和自杀倾向之间的关系。

先前的研究表明，青少年身份障碍与自杀倾向之间存在正相关关系；然而，这些关系背后的机制尚不清楚。作者提出，边缘特征和各种内化障碍可能会调节这些关系。本研究的目的是使用结构方程模型测试这些结构之间关联的多重中介模型。96 名 12-17 岁的住院青少年完成了青少年身份发展评估、DSM-IV 边缘型人格障碍的童年访谈、青年自我报告和哥伦比亚自杀严重程度评定量表。研究结果部分证实了理论模型。边缘特征介导了身份障碍对自杀意念严重程度的积极影响。证明了退缩/抑郁和焦虑/抑郁对身份破坏对自杀意念强度的影响的中介作用。对于有自杀意念的青年，身份认同障碍以及边缘和抑郁症状可能是干预措施的目标。
