Background: The aim of this study was to verify the efficacy of lifestyle self-monitoring for the improvement of the IBS and reveal what has been changed due to the intervention. Methods: A total of 111 nursing school students were randomized into three groups, two intervention groups (a two-month intervention group, n = 34, and a four-month intervention group, n = 35) and a control group (n = 34). The intervention groups conducted lifestyle self-monitoring in conjunction with a 15-minutes group work for either two or four months. The primary outcome measure was Rome II criteria for IBS. Other outcome measures were the Hospital Anxiety and Depression Scale (HADS) and the Gastrointestinal Symptom Rating Scale (GSRS). They were assessed at the baseline and the end of both of the intervention periods. Analysis was conducted as intention-to-treat. Results: The prevalence of IBS did not change significantly after the intervention in any of the groups. The HAD-A score, a subscale of the HADS score for anxiety, decreased 1.4 points in the two-month intervention group (p = 0.02) and 2.3 points in the four-month intervention group of (p = 0.01) after intervention. The average GSRS decreased 0.2 points in the control group (p = 0.05) and 0.3 points in the four-month intervention group (p < 0.01). Conclusions: Lifestyle self-monitoring for two or four months did not reduce the prevalence of the IBS significantly, but it did decrease anxiety and improved the QOL related to gastrointestinal symptoms in female nursing school students.
