What this trial studies

This study focuses on the psychological and emotional challenges faced by individuals with Crohn's disease, aiming to improve their quality of life through a combination therapy approach. Participants will engage in an IBD Coping Strategies Program alongside a Time and Attention Control IBD Support Program. The study targets adults aged 18-65 with active Crohn's disease symptoms and requires participants to be planning to start anti-TNF therapy. The goal is to assess the impact of behavioral therapy on both psychological well-being and disease activity.

Why it matters

Potential benefit: If successful, this approach could significantly enhance the quality of life for patients with Crohn's disease by addressing both psychological and physical symptoms.

How similar studies have gone: Previous studies have indicated that psychological interventions can positively influence disease outcomes in similar patient populations.
