Emotion Regulation in Teen Parasuicide and Depression

描述（由申请人提供）：青春期的准自杀行为标志着以后自杀的显著风险，可能是边缘型人格障碍（BPD）发展的前兆。目前关于副自杀和BPD的理论表明，情绪失调是自我伤害行为的基础，它可以调节压倒性的负面情绪。然而，目前还没有研究深入探讨副自杀的情绪失调模型，包括这一特征的认知和生理测量。本研究将比较有自杀倾向的青少年与正常对照组和重度抑郁症临床对照组（n=25/组）的情绪调节行为和生理指标。青少年和他们的父母将完成访谈和自我报告，包括情绪调节、精神病理、药物使用和滥用以及准自杀行为史。生理评估将在基线期间由父母和青少年进行，情感唤起的电影片段“冠军”，以及解决问题的讨论。生理指标包括皮电反应（EDR）、呼吸性窦性心律失常（RSA）和心脏射血前期（PEP）。

DESCRIPTION (provided by applicant): Parasuicidal behavior in adolescence marks significant risk for later suicide and may represent a precursor to the development of borderline personality disorder (BPD). Current theories of parasuicide and BPD suggest that emotion dysregulation underlies the act of self-harm, which serves to regulate overwhelming negative affect. However, no studies have thoroughly explored an emotion dysregulation model of parasuicide, including both cognitive and physiological measures of this trait. The proposed research will compare parasuicidal teens with normal controls and a clinical comparison group with major depressive disorder (n=25/group) on behavioral and physiological measures of emotion regulation. Adolescents and their parent will complete interviews and self-report measures of emotion regulation, psychopathology, substance use and abuse, and histories of parasuicidal behavior. Physiological assessments will be conducted with both the parent and adolescent during baseline, an emotionally evocative film clip from "The Champ," and a problem-solving discussion. Physiological indices include electrodermal responding (EDR), respiratory sinus arrhythmia (RSA), and cardiac pre-ejection period (PEP).
