Background: Challenges and inconsistencies in defining nonsuicidal self-injury (NSSI) have persisted for decades, which significantly impact NSSI conceptualization and assessment in clinical and research settings and impede the field's progress. Aims: The present study aimed to solicit opinions from individuals with NSSI expertise so as to improve the operational definition and conceptualization of NSSI. Method: We asked researchers, clinicians, and graduate students with varying NSSI expertise to provide opinions on six NSSI definitional components (e.g., whether pain should be a required outcome), as well as to review 118 behaviors and indicate whether each is NSSI. Results: Responses (N = 159) revealed good agreement on specific NSSI definitional aspects and the classification of oft-cited NSSI behaviors. However, findings also demonstrated potential discrepancies in how clinicians and researchers define NSSI when compared with specific behaviors that might be classified as NSSI. Limitations: The opinions of the study's sample may not reflect the wider NSSI field. Conclusion: Findings suggest that there is an increased need for a clear and consistent definition of NSSI and specific NSSI behaviors. There is also a need to develop new assessment measures that capture the range of NSSI behaviors that received good-to-excellent agreement among self-injury experts.

澄清非自杀性自残的定义。

背景：定义非自杀性自残（NSSI）的挑战和矛盾一直持续了数十年，这极大地影响了NSSI在临床和研究环境中的概念化和评估，并阻碍了该领域的进展。目的：本研究旨在征求具有NSSI专业知识的个人的意见，以改善NSSI的运营定义和概念化。方法：我们要求具有不同NSSI专业知识的研究人员，临床医生和研究生就六个NSSI定义成分（例如，是否应按疼痛要求提供疼痛）提供意见，并复查118种行为并指出每个行为是否都是NSSI。结果：回答（N = 159）显示出在特定的NSSI定义方面和经常被引用的NSSI行为的分类方面的一致性。然而，研究结果还表明，与可能被归类为NSSI的特定行为相比，临床医生和研究人员对NSSI的定义存在潜在差异。局限性：研究样本的观点可能无法反映出更广泛的NSSI领域。结论：研究结果表明，对NSSI和特定NSSI行为的清晰一致的定义的需求日益增加。还需要开发新的评估措施，以捕获自伤专家之间达成良好至优秀协议的NSSI行为的范围。研究结果表明，越来越需要对NSSI和特定NSSI行为进行清晰，一致的定义。还需要开发新的评估措施，以捕获自伤专家之间达成良好至优秀协议的NSSI行为的范围。研究结果表明，越来越需要对NSSI和特定NSSI行为进行清晰，一致的定义。还需要开发新的评估措施，以捕获自伤专家之间达成良好至优秀协议的NSSI行为的范围。
