BackgroundThere is ample evidence showing that childhood maltreatment (CM) is a risk factor for the development of depression in adulthood. However, little is known about the psychological processes mediating this relationship. This study used a large community sample to investigate the mediating role of emotional, cognitive and/or interpersonal dysfunctions on the one hand and posttraumatic stress disorder symptoms on the other hand.MethodsOne thousand twenty seven participants of a community sample filled out an online survey. Mediation analyses were computed via linear structural equation modelling.ResultsResults showed a significant mediation of the association between CM and adult depression via emotional impairments, depressogenic attribution style and symptoms of posttraumatic stress disorder. Our study design was cross-sectional and therefore did not allow testing temporal precedence of mediators and causality. Data was collected retrospectively, a confounding effect of current depressive symptoms on retrospective recall of CM therefore cannot be ruled out.ConclusionsThe a priori mediation model showed a good fit with the data. The model suggests promising objectives for further research on CM-related depression and potential treatment targets in the future.

BackgroundChildhood maltreatment (CM) has been shown to be related to a severe and/or chronic course of depression. This study investigated which psychological processes mediate this relationship.MethodA large sample of acute or recovered depressed individuals (N=340) participated in an online survey assessing characteristics of depression, trauma exposure, and potential mediators (emotion regulation difficulties, attributional style, and attachment).ResultsThe experience of CM was related to more severe depression and more depressive episodes. In multiple mediation models, emotion dysregulation, a depressogenic attributional style, and avoidance in close relationships conjointly mediated the relationship between CM and depression severity as well as number of depressive episodes. However, a significant direct path between CM and depression characteristics remained. Exploratory analyses suggested that posttraumatic stress disorder symptom severity was an important additional mediator in our sample.ConclusionsOur findings provide preliminary evidence for psychological mediators between CM and depression that may be promising targets for interventions tailored for the treatment of depression in this subgroup.Highlights of the article Childhood maltreatment (CM) is related to more severe depression. The study investigates how this relationship can be explained.CM was related to difficulties in emotion regulation, relationships and thinking style, and symptoms of posttraumatic stress disorder.Statistical analyses showed that these four variables were also able to (partly) explain how CM is related to more severe depression.Treatment for depression in individuals who have experienced CM may need to directly target these variables.

Zusammenfassung. Ziel dieser Arbeit war die Erprobung und Validierung einer deutschen Version der Dialectical Behavior Therapy Ways of Coping Checklist (DBT-WCCL, Neacsiu, Rizui, Vitaliano, Lynch & Linehan, 2010 ), einem Fragebogen zur Erhebung der Häufigkeit der Nutzung von Skills, wie sie im Rahmen der Dialektisch-Behavioralen Therapie (DBT) vermittelt werden. Hierzu bearbeiteten 150 Patientinnen mit Borderline Persönlichkeitsstörung eine deutschsprachige Übersetzung, sowie Fragebögen zur Symptomschwere. Weitere 40 Patientinnen füllten die DBT-WCCL im Rahmen einer stationären DBT zu 5 Messzeitpunkten aus. Die drei Faktoren der Originalversion ließen sich replizieren. Weiterführende Analysen zeigten gute interne Konsistenzen und Retest-Reliabilitäten. Erwartungsgemäße Zunahmen auf der Subskala zur Erfassung von Skillsanwendung während der stationären DBT sowie erwartungsgemäße Zusammenhänge der DBT-WCCL mit der Skills- und DBT-Erfahrung geben erste Hinweise auf die Validität des Verfahrens.
