Emotion Regulation in Teen Parasuicide and Depression

描述（由申请人提供）：青春期的自杀行为标志着以后自杀的重大风险，可能是边缘型人格障碍（BPD）发展的前兆。目前的准自杀和BPD理论认为，情绪失调是自我伤害行为的基础，自我伤害行为有助于调节压倒性的负面情绪。然而，没有研究已经彻底探讨了一个情绪失调模型的parasuicide，包括这一特点的认知和生理措施。拟议的研究将比较parasuicidal青少年与正常对照组和临床对照组与重性抑郁症（n=25/组）的行为和生理措施的情绪调节。青少年和他们的父母将完成访谈和自我报告的情绪调节措施，精神病理学，物质使用和滥用，和历史的parasuicidal行为。生理评估将与父母和青少年在基线，情感唤起电影剪辑从“冠军”，和解决问题的讨论。生理指标包括皮肤电反应（EDR）、呼吸性窦性心律不齐（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).
