Nonsuicidal self-injury (NSSI) by proxy is the intentional destruction of one's own body tissue through the elicitation of another being's actions. Despite its clinical relevance, research on NSSI by proxy is limited and there are no available measures of this behavior. This research aimed to characterize NSSI by proxy among young adults and provide preliminary data on the validity of a new self-report measure, the NSSI by Proxy Questionnaire (NSSIBPQ). Two nationwide community samples of young adults (one general community sample and one with a history of traditional NSSI and suicidality) completed online studies. NSSI by proxy was reported by 18% of the general community sample and 45% of the self-injuring sample. Findings support the clinical relevance of NSSI by proxy and its potential to meet criteria for an NSSI disorder diagnosis. Results also provide preliminary support for the internal consistency and convergent, discriminant, and concurrent validity of the NSSIBPQ.
代理性自伤是指通过引发他人的行为来故意破坏自己的身体组织。尽管代理性自伤具有临床相关性，但针对该行为的研究有限，且目前尚无可用的评估工具。本研究旨在描述年轻成年人中的代理性自伤行为，并提供一种新的自陈式评估工具——代理性自伤问卷（NSSIBPQ）的初步有效性数据。两个全国性的年轻成年人社区样本（一个普通社区样本和一个有传统自伤和自杀史的样本）完成了在线研究。普通社区样本中有 18%的人报告了代理性自伤，而自伤者样本中有 45%的人报告了代理性自伤。研究结果支持了代理性自伤的临床相关性，以及其符合自伤障碍诊断标准的可能性。结果还初步支持了 NSSIBPQ 的内部一致性、聚合效度、区分效度和同时效度。
