Non-suicidal self-injury (NSSI) is becoming an increasingly prevalent phenomenon among adolescents, endangering their health. The aims of this study were to 1) explore the associations between borderline personality features, alexithymia and NSSI and 2) examine if alexithymia mediates the relationships between borderline personality features and both the severity of NSSI and the various functions that maintain NSSI in adolescents.
This cross-sectional study recruited 1779 outpatient and inpatient aged 12-18 years from psychiatric hospitals. All adolescents completed a structured four-part questionnaire including demographic items, the Chinese version of the Functional Assessment of Self-Mutilation, the Borderline Personality Features Scale for Children and the Toronto Alexithymia Scale.
The structural equation modelling results indicated that alexithymia partially mediated the associations between borderline personality features and both the severity of NSSI and the emotion regulation function of NSSI ( = 0.058 and 0.099, both p < 0.001), after controlling for age and sex.
These findings suggest that alexithymia may play a role in the mechanism and treatment of NSSI among adolescents with borderline personality features. Further longitudinal studies are essential to validate these findings.
非自杀性自伤（NSSI）在青少年中日益普遍，危及他们的健康。本研究的目的是：1）探讨边缘型人格特征、述情障碍与NSSI之间的关联；2）检验述情障碍是否在边缘型人格特征与青少年NSSI严重程度以及维持NSSI的各种功能之间的关系中起中介作用。
这项横断面研究从精神病医院招募了1779名12至18岁的门诊和住院患者。所有青少年都完成了一份结构化的四部分问卷，包括人口统计学项目、中文版的自我伤害功能评估、儿童边缘型人格特征量表和多伦多述情障碍量表。
结构方程模型结果表明，在控制年龄和性别后，述情障碍部分中介了边缘型人格特征与NSSI严重程度以及NSSI情绪调节功能之间的关联（分别为0.058和0.099，p均<0.001）。
这些发现表明，述情障碍可能在有边缘型人格特征的青少年NSSI的机制和治疗中起作用。进一步的纵向研究对于验证这些发现至关重要。
