本研究利用生态瞬间评估(EMA)来加深对非自杀性自我伤害(NSSI)思维强度和持续时间是否影响NSSI行为和潜在替代NSSI行为的理解。自伤青少年和青壮年(N=47)被随机要求使用EMA完成NSSI思维(即发生、强度、持续时间)和行为(即参与度、频率、持续时间和方法)的测量，持续两周。最常见的NSSI认为持续时间为1-30分钟。认为NSSI强度较高的个体更有可能自我伤害。NSSI思维强度和持续时间交互作用预测NSSI频率、持续时间、NSSI方法的数量和切割的可能性，使得NSSI思维强度和这些结果之间的正向关系在NSSI思维持续时间较长时变得更强。根据NSSI的想法，最常见的非NSSI行为是推开想法，与他人交谈，以及分心(例如，外出)。参与者很少支持使用社交媒体或在线NSSI支持小组来代替NSSI。在长时间内抵制强烈的NSSI想法可能会耗尽结束NSSI情节所需的自我调节资源，导致NSSI频率更高、持续时间更长、NSSI方法更多。加强社会支持可能有助于减少NSSI。
This study utilized ecological momentary assessment (EMA) to sharpen understanding of whether non-suicidal self-injury (NSSI) thought intensity and duration impacts NSSI behavior and potential alternative behaviors to NSSI. Self-injuring adolescents and young adults (N = 47) were randomly prompted using EMA to complete measures of NSSI thoughts (i.e., occurrence, intensity, duration) and behavior (i.e., engagement, frequency, duration, and methods) for two weeks. The most common NSSI thought duration was 1-30 min. Individuals with higher NSSI thought intensity were more likely to self-injure. NSSI thought intensity and duration interacted to predict NSSI frequency, duration, the number of NSSI methods, and the likelihood of cutting such that the positive relationship between NSSI thought intensity and these outcomes became stronger at longer NSSI thought durations. The most commonly endorsed non-NSSI behaviors following NSSI thoughts were pushing thoughts away, talking to others, and distraction (e.g., going out). Participants rarely endorsed using social media or online NSSI support groups in lieu of NSSI. Resisting intense NSSI thoughts over prolonged time periods may deplete the self-regulatory resources required to terminate NSSI episodes once they have begun, leading to greater NSSI frequency, longer NSSI duration, and more NSSI methods. Bolstering social support may help to reduce NSSI.
