Nonsuicidal self-injury is a burgeoning mental health concern amongst post-secondary students. In the present study, the link between posttraumatic stress symptoms (PTSS) and nonsuicidal self-injury (NSSI) was examined among post-secondary students over time, while accounting for the role of co-occurring depressive symptoms. Participants were 841 first-year university students with self-reported lifetime histories of trauma who reported on traumatic experiences, PTSS, depressive symptoms, and NSSI at three time points over the course of their first year of university. This study also included exploratory correlational analyses of the relation among PTSS and motivations for NSSI engagement. As expected, PTSS predicted NSSI engagement among students within and across time, though effects were small. The strongest correlations were among PTSS and engaging in NSSI for the purposes of fulfilling self-punishment desires and anti-dissociation (e.g., to reduce feelings of numbness). This study provides further support for theories underscoring NSSI as a means of coping with intra- and interpersonal distress among post-secondary students experiencing stressful life events, such as trauma.
非自杀性自伤是大专学生中日益受到关注的心理健康问题。在本研究中，对大专学生创伤后应激症状（PTSS）与非自杀性自伤（NSSI）之间的联系进行了长期考察，同时考虑了共病抑郁症状的作用。参与者为841名有自我报告终生创伤史的大学一年级学生，他们在大学一年级期间的三个时间点报告了创伤经历、PTSS、抑郁症状和NSSI。本研究还对PTSS与NSSI行为动机之间的关系进行了探索性相关分析。正如预期的那样，PTSS在不同时间点预测了学生中的NSSI行为，尽管影响较小。最强的相关性存在于PTSS与为满足自我惩罚欲望和抗解离目的（如减轻麻木感）而进行的NSSI行为之间。本研究为强调NSSI是经历创伤等压力性生活事件的大专学生应对内部和人际困扰的一种方式的理论提供了进一步支持。
