Background-Adverse child environments are associated the onset of mood and anxiety disorders in adulthood. The mechanisms underlying these life-course associations remain poorly understood. We investigate whether emotional reactivity to stress is a mechanism in the association between childhood environment characteristics and adult mood and anxiety disorders.

Objective: This study tested whether insecure attachment mediates the link between childhood trauma and adult somatization. Methods: A community sample of 101 couples completed self-report measures, including the Relationship Scales Questionnaire, the Childhood Trauma Questionnaire, the Somatic Symptom Inventory, the Beck Depression Inventory, and the Conflict Tactics Scale. Results: Childhood trauma was associated with higher levels of somatization and insecure attachment. Insecure attachment style was also associated with higher levels of somatization. Controlling for age, income, and recent intimate partner violence, analyses showed that fearful attachment fully mediated the link between childhood trauma and somatization for women. For men, there was no such mediation, but both childhood trauma and insecure attachment styles made independent contributions to predicting levels of somatization. Conclusions: Findings are consistent with the hypothesis that, for women, childhood trauma influences adult levels of somatization by fostering insecure adult attachment. For men, findings suggest that trauma and attachment are both important independent predictors of adult somatization. Study results support the idea that childhood trauma shapes patients' styles of relating to others in times of need, and these styles, in turn, influence the somatization process and how patients respond to providers. Screening for attachment style may provide information that could allow health care providers to tailor treatment more effectively.
