Self-harm may have several reasons, and these reasons may have corresponding implied goals. The current study examined reasons for self-harm and whether the a priori goals intended by these reasons were achieved. Fifty-seven individuals with a history of self-harm were recruited online and volunteered their time to complete a series of online questionnaires assessing past self-harm frequency, self-harm reasons, whether the goal associated with these reasons was achieved, and future self-harm intent. Reasons to reduce tension and dissociation associated with more past self-harm, a higher intent to self-harm again, and it was reported that the goals associated with reasons were achieved (i.e., these internal states were extinguished). Achievement of these goals (i.e., reported reductions in tension and dissociation) mediated the relation between corresponding self-harm reasons and intent to self-harm in the future. Findings support the view that self-harm is a maladaptive coping strategy and the reinforcement component of the experiential avoidance model of self-harm. Results have clinical implications and heuristic value for future research, which are discussed.
自我伤害可能有多种原因,且这些原因可能有相应的隐含目标。本研究考察了自我伤害的原因以及这些原因所意图的先验目标是否得以实现。通过网络招募了57名有自我伤害史的个体,他们自愿花时间完成一系列在线问卷,这些问卷评估过去自我伤害的频率、自我伤害的原因、与这些原因相关的目标是否实现以及未来自我伤害的意图。与更多过去的自我伤害、再次自我伤害的更高意图相关的减轻紧张和分离的原因,并且报告称与原因相关的目标得以实现(即这些内部状态得以消除)。这些目标的实现(即报告的紧张和分离的减轻)介导了相应的自我伤害原因与未来自我伤害意图之间的关系。研究结果支持了这样一种观点,即自我伤害是一种适应不良的应对策略以及自我伤害体验性回避模型的强化成分。研究结果对未来研究具有临床意义和启发价值,将对此进行讨论。
