摘要

目的:以往的研究已经将自伤与各种心理、社会和环境因素联系起来,但这些因素在不同发育阶段的相对重要性尚不清楚。本研究利用随机森林分类器对中国初高中学生自伤相关的多维因素进行了调查,为有针对性的干预提供信息。方法:共2735名中国学生提供自伤行为、自伤行为功能及相关因素的自述数据。该研究利用随机森林分类器识别不同时间段(上个月、过去6个月和过去一年)与自伤相关的关键因素,并在初中生和高中生队列中比较这些因素。结果:随机森林模型对中学生自伤有较好的判别能力(AUC = 0.84;AUC = 0.79,高中生),特异度高(94.7 ~ 97.3%),敏感性低(27.6 ~ 42.8%)。中学生的抑郁焦虑症状、社会支持、消极自我评价和自我控制是主要影响因素。在高中生中,抑郁、焦虑、羞耻相关图式、情绪虐待和执行功能缺陷是主要因素。在报告自伤的亚组中,不同发育阶段观察到不同的动机和因素。结论:中国青少年自伤行为受情绪、心理、社会和认知因素复杂的相互作用影响,且初中生和高中生的自伤行为具有明显的发展差异。这些发现强调需要针对青少年群体的发育阶段制定针对性的预防和干预策略。

Factors Associated with Non-Suicidal Self-Injury Among Middle and High School Students in China Using a Random Forest Classifier.

Objectives: Previous research has linked NSSI to various psychological, social, and environmental factors, but the relative importance of these factors across different developmental stages remains unclear. This study investigates the multidimensional factors associated with NSSI among middle and high school students in China using a Random Forest Classifier to inform targeted interventions.

Methods: A total of 2735 Chinese students provided self-reported data on NSSI behavior, functions of NSSI behavior, as well as a number of associated factors. The study utilized a Random Forest Classifier to identify key factors related to NSSI across different time periods (last month, past 6 months, and past year), and compared these factors between middle school and high school student cohorts.

Results: The Random Forest models showed good discriminative ability for identifying NSSI (AUC = 0.84 for middle school; AUC = 0.79 for high school students), with high specificity (94.7-97.3%) but low sensitivity (27.6-42.8%). For middle school students, depressive and anxiety symptoms, social support, negative self-evaluation, and self-control were primary factors. For high school students, depression, anxiety, schemas related to shame, emotional abuse, and executive functioning deficits were found primary factors. Within the subgroup who reported NSSI, differing motivations and factors were observed across developmental stages.

Conclusions: NSSI behavior in Chinese adolescents is influenced by a complex interplay of emotional, psychological, social, and cognitive factors, with clear developmental distinctions between middle and high school students. These findings underscore the need for tailored prevention and intervention strategies that are sensitive to the developmental stage of the adolescent population.
