Attachment insecurity mediates the relationship between childhood trauma and eating disorder psychopathology in a clinical sample: A structural equation model

Objectives: Childhood maltreatment occurs often among those with an eating disorder and is considered a nonspecific risk factor. However, the mechanisms by which childhood maltreatment may lead to an eating disorder are not well understood. The current study tests a model in which attachment insecurity is hypothesized to mediate the relationship between childhood maltreatment and eating disorder psychopathology. Method: Treatment seeking adults with eating disorders (N = 308) completed questionnaires about childhood maltreatment, eating disorder psychopathology, and adult attachment. Results: Structural equation models indicated that childhood trauma had a direct effect on eating disorder symptoms. Also, attachment anxiety and avoidance each equally mediated the childhood maltreatment to eating disorder psychopathology relationship. Conclusions: Attachment insecurity, characterized by affect dysregulation and interpersonal sensitivities may help to explain why eating disorder symptoms may be one consequence of childhood maltreatment in a clinical sample. Clinicians treating primarily those with trauma might assess for disordered eating as a potential manifestation of the sequelae of trauma and attachment insecurity. (C) 2013 Elsevier Ltd.
