Childhood maltreatment may play an important role in the transition from suicidal ideation to suicidal behavior. Recently, research has begun evaluating the association between childhood maltreatment and involuntary and distressing intrusions about one's own suicide, also called suicidal intrusions. This cross-sectional, multicenter study aimed to investigate the association between childhood maltreatment and the severity of suicidal intrusions using online questionnaires. Participants were suicidal outpatients currently receiving treatment at a Dutch mental health institution (N = 149). The Childhood Trauma Questionnaire–Short Form and Suicidal Intrusions Attributes Scale were administered online. A simple linear regression was performed followed by a multiple linear regression with backward selection to separate the predictors of childhood maltreatment subscales. Next, significant predictor variables were used to perform an additional regression analysis with gender, age, posttraumatic stress disorder (PTSD) diagnosis, and depressive symptoms as potential covariates. The results showed that childhood maltreatment was significantly associated with suicidal intrusion scores, B = .22, t(147) = 2.010, p = .046. A multiple linear regression analysis showed that the only specific form of childhood maltreatment associated with suicidal intrusions was sexual abuse; the association remained after controlling for age, gender, PTSD diagnosis and depressive symptoms, F(5, 143) = 11.15, p < .001. In summary, the present study confirms the link between childhood maltreatment, particularly childhood sexual abuse, and suicidal intrusions. This finding implies that in the treatment of suicidal intrusions and suicidality, childhood sexual abuse should be identified and targeted with evidence-based treatments for PTSD.

童年虐待与自杀入侵之间的关联：一项横断面研究


童年虐待可能在自杀意念到自杀行为的转变中发挥重要作用。最近，研究开始评估儿童时期的虐待与对自己自杀的非自愿和痛苦的侵入（也称为自杀侵入）之间的关联。这项横断面、多中心研究旨在通过在线问卷调查儿童虐待与自杀入侵严重程度之间的关联。参与者是目前在荷兰精神卫生机构接受治疗的有自杀倾向的门诊患者（ N = 149）。儿童创伤问卷——简式和自杀侵入属性量表是在线进行的。进行简单线性回归，然后进行向后选择的多元线性回归，以分离儿童虐待子量表的预测因子。接下来，使用显着的预测变量进行额外的回归分析，其中性别、年龄、创伤后应激障碍（PTSD）诊断和抑郁症状作为潜在的协变量。结果显示，童年虐待与自杀入侵评分显着相关， B = .22， t (147) = 2.010， p = .046。多元线性回归分析表明，与自杀侵入相关的儿童虐待的唯一具体形式是性虐待；在控制了年龄、性别、PTSD 诊断和抑郁症状后，这种关联仍然存在， F (5, 143) = 11.15, p < .001。总之，本研究证实了儿童期虐待，特别是儿童期性虐待与自杀入侵之间的联系。 这一发现意味着，在治疗自杀侵入和自杀倾向时，应识别儿童性虐待，并针对 PTSD 进行循证治疗。
