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.

澄清非自杀性自伤的定义。

背景：定义非自杀性自伤 (NSSI) 的挑战和不一致已经持续了数十年，这对临床和研究环境中的 NSSI 概念化和评估产生了重大影响，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，以改进 NSSI 的操作定义和概念化。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 NSSI 定义的六个组成部分（例如，疼痛是否应该是必需的结果）提供意见，并审查 118 种行为并指出每种行为是否为 NSSI。结果：响应（N = 159）显示在特定 NSSI 定义方面和经常被引用的 NSSI 行为分类方面有很好的一致性。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如何定义 NSSI 存在潜在差异。局限性：研究样本的意见可能无法反映更广泛的 NSSI 领域。结论：研究结果表明，对 NSSI 和特定 NSSI 行为的明确和一致定义的需求增加。还需要制定新的评估措施，以捕捉在自伤专家之间获得良好至优秀协议的 NSSI 行为范围。研究结果表明，对 NSSI 和特定 NSSI 行为的明确和一致的定义越来越需要。还需要开发新的评估措施，以捕捉在自伤专家之间获得良好至优秀协议的 NSSI 行为范围。研究结果表明，对 NSSI 和特定 NSSI 行为的明确和一致的定义越来越需要。还需要开发新的评估措施，以捕捉在自伤专家之间获得良好至优秀协议的 NSSI 行为范围。
