OBJECTIVE: We assessed the effect of reported sexual abuse on symptom severity and health-related quality of life in patients with severe irritable bowel syndrome (IBS) undergoing psychological treatments. METHODS: IBS patients entering a treatment trial who reported prior sexual abuse were compared with the remainder in terms of symptom severity and health-related quality of life (SF-36) at trial entry and 15 months later. Analyses used ANCOVA with age, sex, marital status, and treatment group as covariates. We assessed possible mediators using multiple regression analysis. RESULTS: Of 257 patients with severe IBS, 31 (12.1%) reported a history of rape and 28 (10.9%) reported forced, unwanted touching. People who reported abuse were more impaired than the remainder on the SF-36 scales for pain (adjusted p = .023) and physical function (p = .029); these relationships followed a "dose-response" relationship and were mediated by SCL-90 somatization score. At 15 months follow-up, the associations between reported abuse and SF-36 scores were lost because people with reported abuse, especially rape, improved more than the remainder when treated with psychotherapy or paroxetine (selective serotonin reuptake inhibitor antidepressant); this improvement was mediated by change in SCL-90 somatization score. CONCLUSIONS: In severe IBS, the association between self-reported sexual abuse and impaired functioning is mediated by a general tendency to report numerous bodily symptoms. A reported history of abuse is associated with a marked improvement following psychological treatment.
