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. The present study aimed to solicit opinions from individuals with NSSI expertise so as to improve the operational definition and conceptualization of NSSI. 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. Responses ( = 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. The opinions of the study's sample may not reflect the wider NSSI field. 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.
几十年来，非自杀性自伤（NSSI）的定义一直存在挑战和不一致，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。本研究旨在征求具有 NSSI 专业知识的个人的意见，以改善 NSSI 的操作性定义和概念化。我们要求具有不同 NSSI 专业知识的研究人员、临床医生和研究生对六个 NSSI 定义组成部分（例如，是否应将疼痛作为必需的结果）提供意见，并审查 118 种行为，并指出每种行为是否属于 NSSI。（= 159）的回复结果显示，在特定的 NSSI 定义方面以及经常被引用的 NSSI 行为分类方面，具有良好的一致性。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对 NSSI 的定义可能存在差异。该研究样本的意见可能无法反映更广泛的 NSSI 领域。研究结果表明，需要明确和一致的 NSSI 定义以及具体的 NSSI 行为定义。还需要开发新的评估措施，以捕捉到自我伤害专家之间达成良好至优秀共识的各种 NSSI 行为。
