A pilot randomized controlled trial of the self-management assistance for recommended treatment inflammatory bowel disease app for adolescents with inflammatory bowel disease.

We examined the use of a mobile self-management assistance for recommended treatment (SMART) inflammatory bowel disease (IBD) app to improve health outcomes compared to an attention control (AC) arm in adolescents with IBD. Thirty-five participants (M = 15 years; 48% female, 75% white) were randomly assigned to the SMART IBD app or AC arm and completed daily diaries at baseline followed by a 1-month intervention and then completed the same daily diaries at post-treatment. Results demonstrated a significant treatment by time effect for perceived stress (F = 4.32, p < 0.05) and sleep quantity (F = 7.74, p < 0.01), with participants receiving the SMART IBD app intervention reporting a significant decrease in stress and increase in average sleep quantity from baseline to post-treatment compared to the AC arm. Using the SMART IBD app may improve health outcomes important to the overall management of IBD.
