Nonsuicidal self-injury (NSSI) occurs more frequently in the prisoner population than in the general population. Monitoring and management of this behavior is challenging because NSSI may present in diverse ways. People often use more than one method of NSSI, and there are many possible combinations of these behaviors. We used latent class analysis (LCA) to identify subgroups of male inmates based on methods and frequency of NSSI.
A total of 1042 male prisoners in China (M = 38.45, SD = 10.67) completed measures of hopelessness, sensation seeking, identity integration, and suicidal ideation, and NSSI was assessed in a structured interview.
Results of the LCA supported a three-class model: high-NSSI (1.8%), moderate-NSSI (8.0%), and no-or-negligible NSSI (90.2%). Multinomial logistic regression analyses showed that prisoners in the high-NSSI and moderate-NSSI classes were significantly more likely than those in the no-or-negligible NSSI class to show high hopelessness, high sensation seeking, and low identity. Furthermore, suicidal ideation was significantly higher in the high-NSSI and moderate-NSSI classes than in the no-or-negligible NSSI class.
Classifying groups of prisoners based on features of NSSI is potentially useful for understanding risk factors and for developing tailored prevention and treatment strategies.
非自杀性自伤（NSSI）在囚犯群体中的发生率高于普通人群。由于 NSSI 可能以多种方式出现，因此对其进行监测和管理具有挑战性。人们经常使用不止一种 NSSI 方法，这些行为有许多可能的组合。我们使用潜在类别分析（LCA）根据 NSSI 的方法和频率对男性囚犯进行分组。
共有 1042 名中国男性囚犯（M=38.45，SD=10.67）完成了绝望感、感觉寻求、身份整合和自杀意念的测量，并且在结构化访谈中评估了 NSSI。
LCA 的结果支持三类别模型：高 NSSI（1.8%）、中 NSSI（8.0%）和无或可忽略不计的 NSSI（90.2%）。多项逻辑回归分析表明，高 NSSI 和中 NSSI 类别的囚犯与无或可忽略不计的 NSSI 类别的囚犯相比，更有可能表现出高绝望感、高感觉寻求和低身份。此外，高 NSSI 和中 NSSI 类别的自杀意念显著高于无或可忽略不计的 NSSI 类别的囚犯。
根据 NSSI 的特征对囚犯进行分组可能有助于了解风险因素，并制定有针对性的预防和治疗策略。
