Several studies provide evidence for a relationship between childhood abuse and suicidality across the lifespan. To examine this association in the context of the Interpersonal Psychological Theory of Suicide (IPTS), we investigated whether its constructs thwarted belongingness, perceived burdensomeness and capability for suicide are potential mediators.
Eighty-four German psychiatric inpatients with unipolar depression (M = 37.6 years, 69% female) and current or lifetime suicidal ideation were included. For the assessment we used the Childhood Trauma Screener (CTS), the Rasch-based Screening for Depression (DESC-I), the Interpersonal Needs Questionnaire (INQ), the German Capability for Suicide Questionnaire (GCSQ), the Beck Scale for Suicide Ideation (BSS) and the Suicide Behaviors Questionnaire-Revised (SBQ-R). Simple and multiple mediator analyses were applied.
Most patients (70%) had experienced childhood abuse. Emotional abuse showed an indirect association with suicidal ideation via thwarted belongingness and perceived burdensomeness, whereas physical and sexual abuse were indirectly related to suicide risk via capability for suicide.
The small sample size and the cross-sectional design are limiting factors of the present study.
Childhood abuse is a common experience of inpatients with unipolar depression. This study showed its indirect effects on suicidal ideation and risk for suicide, mediated by the constructs of the IPTS. Further research should investigate this issue in other populations and clinicians should be aware of the devastating effects of childhood abuse.
多项研究为儿童期虐待与整个生命周期的自杀意念之间的关系提供了证据。为了在自杀的人际关系心理理论（IPTS）的背景下研究这种关联，我们调查了其结构中的归属感受阻、感知负担和自杀能力是否是潜在的中介因素。
纳入 84 名德国单相抑郁住院患者（M=37.6 岁，69%为女性），并伴有当前或终生自杀意念。评估使用儿童期创伤筛查器（CTS）、基于 Rasch 的抑郁筛查（DESC-I）、人际关系需求问卷（INQ）、德国自杀能力问卷（GCSQ）、贝克自杀意念量表（BSS）和修订后的自杀行为问卷（SBQ-R）。采用简单和多重中介分析。
大多数患者（70%）经历过儿童期虐待。情感虐待通过归属感受阻和感知负担与自杀意念呈间接关联，而身体和性虐待通过自杀能力与自杀风险呈间接关联。
本研究的样本量小和横断面设计是其限制因素。
儿童期虐待是单相抑郁住院患者的常见经历。本研究表明，它通过 IPTS 的结构对自杀意念和自杀风险产生间接影响。进一步的研究应该在其他人群中调查这个问题，临床医生应该意识到儿童期虐待的破坏性影响。
