The Functions of Adolescent Self-Injury: Measurement Structure and Clinical Imp

描述(申请人提供)：非自杀性自残(NSSI)是指在没有自杀意图和未经社会批准的目的下故意伤害身体组织的行为。例如割皮、灼伤和抓伤。NSSI是精神障碍和自杀的强大危险因素，并已成为青少年的一个重大公共卫生问题。最近的研究发现，大约8%的初中生、14%-15%的高中生和80%的青少年住院患者参与了NSSI。因为大多数NSSI研究都集中在患病率和心理社会相关性上，所以对NSSI在青少年中的作用知之甚少。了解NSSI的功能将有助于对自伤患者的病例概念化和治疗计划，并为NSSI的病因、分类、预防和治疗的研究提供有意义的背景。其具体目的是：1)确定新的、全面的NSSI功能测量对青少年人群的适用性；2)建立青少年NSSI功能的因素结构；3)检查不同NSSI功能对诊断和治疗的影响，包括识别临床上不同的自伤者亚群。因此，这项研究将提供关于NSSI功能的协变和临床意义的基础数据，并产生第一个全面和有效的NSSI功能测量。公共卫生相关性：非自杀性自我伤害(NSSI)是精神障碍和自杀的强烈危险因素，已成为青少年的一个重大公共卫生问题。由于大多数NSSI研究都集中在患病率和心理社会相关因素上，因此本项目侧重于青少年NSSI的功能，包括其测量、结构和临床意义。

DESCRIPTION (provided by applicant): Non-suicidal self-injury (NSSI) refers to the intentional injuring of one's body tissue without suicidal intent and for purposes not socially sanctioned. Examples include skin-cutting, burning, and scratching. NSSI is a robust risk-factor for psychiatric disorders and suicide and has become a significant public health problem in adolescents. Recent research finds that approximately 8% of middle school students, 14-15% of high-school students, and 80% of adolescent inpatients have engaged in NSSI. Because most NSSI research has focused on prevalence and psychosocial correlates, little is known about the functions of NSSI in adolescents. Understanding the functions of NSSI would facilitate case conceptualization and treatment planning for patients who self-injure, and provide a meaningful context for research on the etiology, classification, prevention, and treatment of NSSI. The specific aims are to: 1) determine the suitability of a new, comprehensive measure of NSSI functions for adolescent populations, 2) establish the factor structure of NSSI functions in adolescents, and 3) examine the implications of different NSSI functions for diagnosis and treatment, including the identification of clinically distinct subgroups of self-injurers. Thus, the study will provide basic data on the covariation and clinical implications of NSSI functions, as well as produce the first comprehensive and valid measure of NSSI functions. PUBLIC HEALTH RELEVANCE: Non-suicidal self-injury (NSSI) is a robust risk-factor for psychiatric disorders and suicide and has become a significant public health problem in adolescents. Because most NSSI research has focused on prevalence and psychosocial correlates, the present project focuses on the functions of adolescent NSSI, including their measurement, structure, and clinical implications.
