Emotion Regulation in Teen Parasuicide and Depression

描述(申请人提供)：青春期的副自杀行为标志着以后自杀的重大风险，并可能是发展为边缘人格障碍(BPD)的先兆。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，自我伤害行为起着调节压倒性负面情绪的作用。然而，还没有研究深入探索副自杀的情绪失调模型，包括对这一特征的认知和生理测量。这项拟议的研究将在情绪调节的行为和生理指标上将副自杀青少年与正常对照组和患有严重抑郁障碍的临床对照组(n=25)进行比较。青少年和他们的父母将完成情绪调节、精神病理学、药物使用和滥用以及副自杀行为史的访谈和自我报告。在基线期间，将与父母和青少年进行生理评估，《冠军》中一段激动人心的电影片段，以及解决问题的讨论。生理指标包括电皮肤反应(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).
