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 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 Mediations of withdrawn/depression and anxiety/depression on the effect of identity disruption on suicidal ideation intensity were demonstrated.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.
先前的研究表明，在青少年中，身份障碍与自杀意念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。本研究旨在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 名年龄在 12-17 岁的住院青少年完成了青少年身份发展评估、边缘型人格障碍儿童访谈、青少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。边缘特征中介了身份障碍对自杀意念严重程度的正向影响。还证明了退缩/抑郁和焦虑/抑郁对身份中断对自杀意念强度影响的中介作用。身份中断以及边缘型和抑郁症状可能是有自杀意念的年轻人干预的目标。
