ABSTRACTObjectiveChildhood trauma is a key public health risk factor for developing physical illness. This study examined how childhood abuse and neglect predict adult somatic symptoms assessed retrospectively and in real time.MethodsParticipants in the HowNutsAreTheDutch project completed the Childhood Trauma Questionnaire—Short Form and, to assess somatic symptoms, the cross-sectional Patient Health Questionnaire (n= 406) or a longitudinal ecological momentary assessment protocol that included responding to an item on physical discomfort 3 times a day for 30 days (n= 290).ResultsAs hypothesized, childhood trauma was positively associated with adult somatic symptoms assessed using the Patient Health Questionnaire (d= 0.30) and assessed using the ecological momentary assessment item (d= 0.31), also after adjustment for age, sex, educational level, and relationship status. Longitudinally, we also explored whether interpersonal context moderated abuse outcomes, and observed that social company dampened momentary physical discomfort among people with a history of more physical neglect (d= 0.04).ConclusionsChildhood trauma, especially emotional and sexual abuse, predicts specific adult somatic symptoms. Future work may examine how symptom expression is influenced by the social lives of traumatized individuals.
