ABSTRACT:
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
