More research is needed to understand the different vulnerability profiles of university students who engage in non-suicidal self-injury (NSSI). This study sought to classify university students (n = 479; 83.8% female) aged 17–25 years (M = 18.77; SD = 1.42) who had engaged in NSSI within the past year into latent profiles based on their self-perceived difficulties in regulating both positive and negative emotions. Independent samples of students who had a past history of NSSI but had not self-injured within the previous year (n = 439; 82.9% females; M_age = 19.03, SD = 1.62) and who had no history of NSSI (n = 1551; 69.9% females; M_age = 19.02, SD = 1.55) were recruited for comparison purposes. Latent cluster analyses revealed three emotion regulation profiles within the NSSI sample—the Average Difficulties (47.4%), Dysregulated (33.0%), and Low Difficulties (19.6%) profiles—each of which differed meaningfully from both comparison samples on mean emotion regulation difficulties. Students across profiles also differed in their self-reported experiences with parents, particularly with fathers (pressure, antipathy, unresolved attachment, psychological control), and in the extent to which they felt alienated from parents. Lastly, students across profiles differed in the frequency, methods, functions, and addictive properties of their NSSI. Findings highlight that university students who self-injure experience distinct patterns of difficulties with emotion regulation, which are associated with variation in parent–child relational risk factors and NSSI outcomes.

需要更多的研究来了解参与非自杀式自残（NSSI）的大学生的不同脆弱性状况。这项研究试图 根据过去一年中自我感觉到的困难，将在过去一年中参与NSSI的 17-25岁（M  = 18.77；SD = 1.42）的大学生（n = 479；女性83.8％）分类为潜在特征。调节正面和负面情绪。具有NSSI既往史但在上一年中未自残的学生的独立样本（n  = 439； 82.9％的女性；M_年龄 = 19.03，SD  = 1.62），并且没有NSSI的历史（n  = 1551） ； 69.9％的女性；中号_年龄 = 19.02，SD = 1.55），以供比较。潜在聚类分析揭示了NSSI样本中的三种情绪调节曲线-平均难度（47.4％），失调（33.0％）和低难度（19.6％）曲线-在平均情绪调节困难方面，这两种曲线均与两个比较样本有显着差异。不同背景的学生在与父母，特别是与父亲的自我报告经历上（压力，反感，未解决的依恋，心理控制）以及他们与父母的疏远程度也有所不同。最后，跨配置文件的学生在其NSSI的频率，方法，功能和成瘾性方面有所不同。研究结果表明，自残的大学生在情绪调节方面会遇到不同的困难模式，
