Identifying transdiagnostic mechanisms that relate to nonsuicidal self-injury (NSSI), the intentional destruction of one's own body tissue without suicidal intent and for purposes not culturally or socially sanctioned, is critical for the development and further refinement of NSSI-focused interventions. Accordingly, the present study aimed to characterize potential roles for anhedonia, repetitive negative thinking, and trait mindfulness as they relate to history of NSSI, NSSI urge-to-action, and NSSI functions. We hypothesized that these variables would relate to NSSI, NSSI urge-to-action, and explored correlations with functions of NSSI: interpersonal (i.e., reinforcement is social) and intrapersonal (e.g., reinforcement is self-focused) functions. Results indicated that greater anhedonia was related to history of NSSI. Among participants who reported history of NSSI, lower levels of trait mindfulness were associated with less time spent between NSSI urge and NSSI action. Finally, amongst participants who reported history of NSSI, interpersonal functions of NSSI were positively correlated with greater anhedonia, while intrapersonal NSSI function was positively correlated with higher levels of repetitive negative thinking, suggesting potential differential mechanisms that may contribute to the maintenance of NSSI. This work highlights transdiagnostic mechanisms that relate to history of NSSI, NSSI urge-to-action latency, and potential differential correlates of NSSI functions.
识别与非自杀性自伤（NSSI）相关的跨诊断机制至关重要，非自杀性自伤是指在没有自杀意图且出于非文化或社会认可目的的情况下故意破坏自己的身体组织。这对于开发和进一步完善以NSSI为重点的干预措施非常关键。因此，本研究旨在描述快感缺乏、反复消极思维和特质正念与NSSI病史、NSSI行动冲动及NSSI功能之间的潜在作用。我们假设这些变量与NSSI、NSSI行动冲动相关，并探讨它们与NSSI功能的相关性：人际功能（即强化是社会性的）和内省功能（例如，强化是以自我为中心的）。结果表明，较高程度的快感缺乏与NSSI病史相关。在报告有NSSI病史的参与者中，特质正念水平较低与NSSI冲动和NSSI行动之间的时间间隔较短有关。最后，在报告有NSSI病史的参与者中，NSSI的人际功能与较高程度的快感缺乏呈正相关，而NSSI的内省功能与较高水平的反复消极思维呈正相关，这表明可能存在导致NSSI持续存在的潜在差异机制。这项工作突出了与NSSI病史、NSSI行动冲动潜伏期以及NSSI功能潜在差异相关性相关的跨诊断机制。
