Can a book, an app, and a mentor ease the burden of Crohn's and colitis?

This study tested whether four free, existing self-help resources could help adults with moderate-to-severe Crohn's disease or ulcerative colitis feel more in control and reduce their disability. Over 800 participants were randomly assigned different combinations of a book, a smartphone app, an online help center, and a peer mentor. The goal was to see if using these tools for 12 weeks improved people's confidence in managing their condition and reduced the daily limitations they face.
