Obsessive-compulsive disorder (OCD) is a disabling mental health problem that affects a significant proportion of the general population. Experiential avoidance appears to account for the development of anxiety and depressive symptoms. However, its relationship with OCD has yielded contradictory results. Furthermore, although OCD-specific thoughts and behaviors, including obsessing, checking, washing, and ordering, have been suggested to significantly predict suicidal ideation and behaviors, this line of research has received scant empirical attention. The overarching aim of this study was to explore the relationship between OCD, OCD-specific behaviors, experiential avoidance, and suicidal experiences.
Overall, 1,046 adults from the community who completed self-report scales participated.
Strong links between overall OCD severity, obsessing, experiential avoidance, and suicidal experiences were established. Results from mediational analyses showed that overall OCD severity and individual obsessive-compulsive thoughts and behaviors were both directly and indirectly linked with suicidal experiences, via experiential avoidance. Obsessing was among the critical obsessive-compulsive symptoms leading to suicidal experiences.
These findings are important because they identify experiential avoidance as a potential key explanatory construct in accounting for the development of OCD and suicidal experiences. However, future research using longitudinal and/or experimental designs is needed to infer causality.
强迫症（OCD）是一种严重影响很大一部分普通人群的心理健康问题。经验回避似乎是焦虑和抑郁症状发展的原因。然而，它与强迫症的关系却产生了相互矛盾的结果。此外，尽管强迫症特有的思维和行为，包括强迫、检查、洗涤和排序，已被证明可以显著预测自杀意念和行为，但这方面的研究几乎没有得到实证关注。本研究的总体目标是探讨强迫症、强迫症特定行为、经验回避与自杀经历之间的关系。
共有 1046 名来自社区的成年人完成了自我报告量表的调查。
建立了强迫症严重程度、强迫观念、经验回避与自杀经历之间的强关联。中介分析的结果表明，强迫症严重程度和个体的强迫性思维和行为都通过经验回避直接或间接地与自杀经历相关联。强迫观念是导致自杀经历的关键强迫症症状之一。
这些发现很重要，因为它们确定了经验回避作为强迫症和自杀经历发展的潜在关键解释性结构。然而，需要使用纵向和/或实验设计的未来研究来推断因果关系。
