自伤行为是全世界死亡的主要原因之一。然而，自我伤害的想法和行为（SITBs）的基本性质并没有得到很好的理解，因为以前的研究依赖于长期的，回顾性的，汇总的，自我报告的评估方法。我们使用生态瞬时评估方法来测量自杀性和非自杀性SITB，因为它们自然实时发生。参与者是30名最近有自伤史的青少年和年轻人，他们在14天的时间内在手持计算机上完成了信号和事件相关评估，收集了1262个思想和行为事件的数据。参与者报告平均每周有5.0次非自杀性自伤（NSSI）的想法，最常见的是中等强度和短时间（1-30分钟），每周有1.6次NSSI。自杀念头发生频率较低（每周1.1次），持续时间较长，并导致自我伤害行为（即，自杀的次数较少。详细报告了SITB最常发生的环境（例如，参与者在做什么，他们和谁在一起，以及他们在每集之前和之后的感受）。这项研究首次揭示了SITB在日常生活中的经历，并对自我伤害行为的科学和临床工作具有重要意义。
Self-injurious behaviors are among the leading causes of death worldwide. However, the basic nature of self-injurious thoughts and behaviors (SITBs) is not well-understood because prior studies have relied on long-term, retrospective, aggregate, self-report assessment methods. We used ecological momentary assessment methods to measure suicidal and non-suicidal SITBs as they naturally occur in real-time. Participants were 30 adolescents and young adults with a recent history of self-injury who completed signal- and event-contingent assessments on handheld computers over a 14-day period, resulting in the collection of data on 1262 thought and behavior episodes. Participants reported an average of 5.0 thoughts of nonsuicidal self-injury (NSSI) per week, most often of moderate intensity and short duration (1–30 minutes), and 1.6 episodes of NSSI per week. Suicidal thoughts occurred less frequently (1.1 per week), were of longer duration, and led to self-injurious behavior (i.e., suicide attempts) less often. Details are reported about the contexts in which SITBs most often occur (e.g., what participants were doing, who they were with, and what they were feeling before and after each episode). This study provides a first glimpse of how SITBs are experienced in everyday life and has significant implications for scientific and clinical work on self-injurious behaviors.
