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

描述（由申请人提供）：非自杀性自伤（NSSI）是指没有自杀意图，出于不受社会认可的目的而故意伤害自己的身体组织。例如皮肤割伤、烧伤和抓伤。自伤是精神疾病和自杀的重要危险因素，已成为青少年的重大公共卫生问题。最近的研究发现，大约8%的初中生、14-15%的高中生和80%的青少年住院患者有过自伤行为。由于大多数自伤研究都集中在患病率和社会心理相关方面，因此对青少年自伤的功能知之甚少。了解自伤的功能有助于对自伤患者进行病例概念化和制定治疗方案，并为自伤的病因、分类、预防和治疗研究提供有意义的背景。具体目的是：1)确定一种新的、综合的青少年自伤功能测量方法的适用性；2)建立青少年自伤功能的因素结构；3)研究不同的自伤功能对诊断和治疗的意义，包括识别临床不同的自伤者亚群。因此，该研究将为自伤功能的共变和临床意义提供基础数据，并产生第一个全面有效的自伤功能测量方法。公共卫生相关性：非自杀性自伤（NSSI）是精神疾病和自杀的一个强有力的危险因素，已成为青少年的一个重要公共卫生问题。由于大多数自伤研究都集中在患病率和社会心理相关方面，因此本项目主要关注青少年自伤的功能，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.
