Although accumulating microlongitudinal research has examined emotion regulatory models of nonsuicidal self-injury (NSSI), few studies have examined how interpersonal contingencies influence daily NSSI behavior. Participants with repeated NSSI (N = 60) provided daily ratings of perceived social support, interpersonal conflict, and NSSI urges and behaviors for 14 days. Consistent with interpersonal models of NSSI, we hypothesized that participants would be more likely to engage in NSSI on days when they experienced high levels of interpersonal conflict, that NSSI acts that were revealed to others would be followed by desirable interpersonal changes (i.e., greater support, less conflict), and that these interpersonal changes would, in turn, predict stronger NSSI urges and more frequent NSSI behavior. Consistent with hypotheses, daily conflict was associated with stronger same-day NSSI urges and greater likelihood of NSSI acts. Perceived support increased following NSSI acts that had been revealed to others, but not unrevealed NSSI acts. This perceived support was, in turn, associated with a stronger NSSI urges and greater likelihood of engaging in NSSI on the following day. Moreover, participants whose NSSI was revealed to others engaged in more total NSSI acts during the diary period than those whose NSSI was not revealed to others. Inconsistent with hypotheses, interpersonal conflict did not decrease following NSSI, regardless of whether or not these acts were revealed to others. Together, these results provide preliminary support for interpersonal reinforcement models of NSSI and highlight the importance of expanding research in this area to include interpersonal contingencies that may influence this behavior.

尽管越来越多的微观纵向研究已经考察了非自杀性自伤（NSSI）的情绪调节模型，但很少有研究考察人际突发事件如何影响日常NSSI行为。有反复NSSI行为的参与者（N = 60）连续14天提供了关于感知到的社会支持、人际冲突以及NSSI冲动和行为的每日评分。与NSSI的人际模型一致，我们假设参与者在经历高水平人际冲突的日子里更有可能进行NSSI，向他人暴露的NSSI行为之后会伴随着理想的人际变化（即更多的支持、更少的冲突），并且这些人际变化反过来会预测更强的NSSI冲动和更频繁的NSSI行为。与假设一致，每日冲突与当日更强的NSSI冲动以及NSSI行为的更大可能性相关。在向他人暴露的NSSI行为之后，感知到的支持增加了，但未暴露的NSSI行为之后则没有。这种感知到的支持反过来又与更强的NSSI冲动以及次日进行NSSI的更大可能性相关。此外，在日记记录期间，NSSI行为向他人暴露的参与者比NSSI行为未向他人暴露的参与者进行的NSSI行为总数更多。与假设不一致的是，无论这些行为是否向他人暴露，NSSI之后人际冲突都没有减少。总之，这些结果为NSSI的人际强化模型提供了初步支持，并强调了扩大该领域研究以纳入可能影响这种行为的人际突发事件的重要性。（PsycINFO数据库记录
