Little is currently known about the repetitive behaviors that take place before, during, and after nonsuicidal self-injury (NSSI). These practice patterns surrounding repetitive self-injury may be part of a habituation process in NSSI. Congruent with the opponent process theory (OPT), the mechanisms through which NSSI is reinforced may include preparation, engagement, and follow-up practice patterns to achieve the desired effect. This may result in increased habituation leading to a change in method and resulting NSSI severity. College students with a history of NSSI (N = 80) completed questionnaires, including an instrument to assess practice patterns around NSSI. High levels of NSSI practice patterns were positively related to various NSSI characteristics and clinical correlates, suggesting higher levels of NSSI severity. Further, NSSI versatility partially explained the relationship between NSSI practice patterns and habituation. Consistent with OPT, practice patterns associated with repetitive NSSI may lead an individual to change methods, fostering habituation to self-injury.
目前对于非自杀性自伤（NSSI）之前、期间和之后发生的重复行为知之甚少。这些围绕重复自伤的行为模式可能是NSSI习惯化过程的一部分。与对立过程理论（OPT）一致，强化NSSI的机制可能包括准备、实施和后续行为模式，以达到预期效果。这可能会导致习惯化增加，从而导致方法改变以及NSSI严重程度改变。有NSSI病史的大学生（N = 80）完成了问卷调查，包括一份评估NSSI相关行为模式的工具。高水平的NSSI行为模式与各种NSSI特征及临床相关因素呈正相关，表明NSSI严重程度更高。此外，NSSI的多样性部分解释了NSSI行为模式与习惯化之间的关系。与OPT一致，与重复性NSSI相关的行为模式可能会导致个体改变方法，促进对自伤的习惯化。
