研究已经确定了十多种非自杀性自伤（NSI）的功能，但这些功能之间的概念和经验重叠仍然不清楚。本研究检查了两个大样本的病人的自伤功能的结构，接受急性护理治疗的自伤。使用两种不同的自伤功能测量来最大限度地扩大研究结果的普遍性：一个样本（n = 946）采用了自伤陈述量表（ISAS； Klonsky和Glenn在《精神病学行为评估杂志》31:15 - 219），另一个样本（n = 211）采用了自残功能评估(FASM； Lloyd等人在青少年社区样本中的自残：描述性特征和临时患病率。行为医学协会年会上的海报会议，新奥尔良，洛杉矶)。探索性因素分析表明，两种测量方法均表现出稳健的双因素结构：一个因素代表人际功能，如情感调节和反分离；另一个因素代表社会功能，如人际影响和同伴关系。为了支持双因素结构的结构效度，这些因素表现出与自伤严重程度指标的相关模式，这与过去的研究和理论一致。研究结果对理论、研究和治疗具有重要意义。特别是，双因素框架应该指导临床评估，以及未来关于自伤功能对病程、预后、治疗和自杀风险的影响的研究。
Research has identified more than a dozen functions of non-suicidal self-injury (NSI), but the conceptual and empirical overlap among these functions remains unclear. The present study examined the structure of NSI functions in two large samples of patients receiving acute-care treatment for NSI. Two different measures of NSI functions were utilized to maximize generalizability of findings: one sample (n = 946) was administered the Inventory of Statements About Self-injury (ISAS; Klonsky and Glenn in J Psychopathol Behav Assess 31:215–219,), and a second sample (n = 211) was administered the Functional Assessment of Self-Mutilation (FASM; Lloyd et al. in Self-mutilation in a community sample of adolescents: descriptive characteristics and provisional prevalence rates. Poster session at the annual meeting of the Society for Behavioral Medicine, New Orleans, LA,). Exploratory factor analyses revealed that both measures exhibited a robust two-factor structure: one factor represented Intrapersonal functions, such as affect regulation and anti-dissociation, and a second factor represented Social functions, such as interpersonal influence and peer bonding. In support of the two-factor structure’s construct validity, the factors exhibited a pattern of correlations with indicators of NSI severity that was consistent with past research and theory. Findings have important implications for theory, research, and treatment. In particular, the two-factor framework should guide clinical assessment, as well as future research on the implications of NSI functions for course, prognosis, treatment, and suicide risk.
