Abstract

Objective: There are numerous risk factors associated with nonsuicidal self-injury (NSSI), contributing to the heterogeneity of the NSSI population. Differences in characteristics may exist between different subgroups. This study attempted to delineate distinct profiles and intervention strategies tailored to specific subgroups of NSSI.

Method: This cross-sectional survey recruited 96,218 participants from 63 universities in China. All variables were measured using corresponding self-report questionnaires. Latent class analysis was conducted to determine different subgroups of NSSI. Analysis of variance and chi-square tests were conducted to investigate the differences across subgroups. Logistic regression analysis was employed to further examine the relationship between subgroups and suicidal thoughts and behaviors.

Results: A total of 8,315 (8.6%) participants reported NSSI, mostly aged 18-24 years. Four subgroups were identified. The largest class, Class 2 (3,488 [41.9%]), predominantly faced mental health challenges, followed by low risk in Class 4 (2,558 [30.8%]), childhood trauma combined with mental health problems in Class 1 (1,323 [15.9%]), and childhood neglect in Class 3 (946 [11.4%]). Class 1 reported the highest rates of a history of psychiatric diagnosis (depression [32.5%]) and exhibited the lowest socioeconomic status. In addition, Class 1 showed the highest odds of reporting suicide plans (OR = 2.36; 95% confidence interval [2.02, 2.76]) and attempts (OR = 3.81; 95% confidence interval [3.14, 4.61]).

Conclusions: This study identified four distinct subgroups of NSSI among youths and decoded their unique profiles. Targeted intervention strategies for each subgroup were crucial, particularly in enhancing the identification and treatment of coexisting childhood trauma, mental health problems, and substance abuse.

用潜在类分析解读非自杀性自伤特征。
目的:与非自杀性自伤(NSSI)相关的危险因素很多,导致了自伤人群的异质性。不同的亚群之间可能存在特征差异。本研究试图描述针对特定亚组自伤的不同概况和干预策略。方法:采用横断面调查方法,在全国63所高校共招募96,218人。所有变量均采用相应的自我报告问卷进行测量。进行潜在分类分析以确定自伤的不同亚组。采用方差分析和卡方检验来研究亚组间的差异。采用Logistic回归分析进一步检验亚组与自杀念头和行为的关系。结果:共有8,315名(8.6%)参与者报告自伤,大多数年龄在18-24岁之间。确定了四个亚组。人数最多的2班(3,488人[41.9%]),主要面临心理健康挑战,其次是低风险的4班(2,558人[30.8%]),1班(1,323人[15.9%])和3班(946人[11.4%])。第一类报告精神病史(抑郁症[32.5%])的比例最高,社会经济地位最低。此外,1级学生报告自杀计划的几率最高(OR = 2.36;95%可信区间[2.02,2.76])和尝试次数(OR = 3.81;95%置信区间[3.14,4.61])。结论:本研究确定了青少年自伤的四个不同亚群,并解读了他们独特的特征。针对每个亚组的有针对性的干预策略至关重要,特别是在加强对共存的儿童创伤、精神健康问题和药物滥用的识别和治疗方面。(PsycInfo Database Record (c) 2025 APA,版权所有)。
