    Abstract:
    OBJECTIVE: Irritable bowel syndrome (IBS) is a common, chronic, and often disabling disorder. Cognitive-behavioral therapy (CBT) has been shown to be effective in alleviating IBS symptoms. The aim of this study was to establish the feasibility and the efficacy of a cognitive-behavioral e-intervention using personal digital assistants (PDAs) on the self-management of IBS patients. METHODS: A feasibility trial was conducted with 38 control group patients receiving standard care and 37 intervention group patients receiving standard care supplemented with a 4-week CBT intervention on PDAs. All patients fulfilled the diagnostic Rome III criteria for IBS. At baseline, 4-week, and 3-month follow-up, patients' abdominal pain, dysfunctional cognitions, IBS quality of life, and pain catastrophizing thoughts were assessed using written questionnaires. RESULTS: Between-group comparisons between baseline and 4 weeks showed more overall quality of life improvement, more improvement in catastrophizing thoughts, and more pain improvement in the intervention group. Only improvement in catastrophizing thoughts persisted in the long-term. No significant differences between groups were found for dysfunctional cognitions. As all 37 intervention group patients completed the intervention and completed diaries three times a day for 4 weeks, the e-health intervention seems feasible. CONCLUSIONS: A cognitive-behavioral intervention on pocket-type computers appears feasible and efficacious for improving IBS-related complaints and cognitions in the short-term. The intervention group improved on several aspects, but most on catastrophizing thoughts, and these improvements even persisted after 3 months. Future studies should focus on unravelling the effective components of this innovative e-health intervention.
