Childhood maltreatment is thought to be associated with suicidality in patients with obsessive–compulsive disorder (OCD). Although the underlying mechanism of this relationship is not clear, cognitive emotion regulation strategies (CERSs) and the specific OC symptoms including unacceptable obsessional thoughts (UOTs) and responsibility for harm (RFH) may underlie this link. Accordingly, the study aimed to assess the effect of childhood maltreatment on suicidal ideation through UOTs, RFH and adaptive and maladaptive CERSs in OCD patients. Three hundred patients meeting a DSM-5 diagnosis of OCD were selected and completed the scales measuring childhood maltreatment, OCD, suicidality and depressive symptoms. After controlling for depressive symptoms and OCD severity, childhood maltreatment was shown to affect suicidal ideation directly. Also, the indirect effect of childhood maltreatment on suicidal ideation was mediated by adaptive CERSs, UOTs and RFH. The findings show that OCD patients with a history of childhood maltreatment, less use of adaptive CERSs and the experiences of UOTs and RFH should be carefully considered regarding suicidal risk.

儿童期虐待通过认知情绪调节策略和强迫症特定的强迫症状对自杀意念的影响

儿童期虐待被认为与强迫症 (OCD) 患者的自杀倾向有关。尽管这种关系的潜在机制尚不清楚，但认知情绪调节策略 (CERS) 和特定的 OC 症状，包括不可接受的强迫思维 (UOT) 和伤害责任 (RFH) 可能是这种联系的基础。因此，该研究旨在通过 UOT、RFH 以及强迫症患者的适应性和适应不良的 CERS 来评估儿童期虐待对自杀意念的影响。选择了 300 名符合 DSM-5 诊断为强迫症的患者，并完成了测量儿童虐待、强迫症、自杀和抑郁症状的量表。在控制了抑郁症状和强迫症严重程度后，儿童虐待被证明直接影响自杀意念。还，儿童期虐待对自杀意念的间接影响是由适应性 CERS、UOT 和 RFH 介导的。研究结果表明，对于有儿童虐待史、较少使用适应性 CERS 以及 UOT 和 RFH 经历的强迫症患者，应仔细考虑自杀风险。
