We examined health-related quality of life, anxiety, and self-image in patients aged 10–20 years with Crohn’s disease (CD) and ulcerative colitis (UC) in remission. These areas are key concerns in clinical care. We used the IMPACT-III for health-related quality of life and The Beck Youth Inventory-II for anxiety and self-image. Linear regression models were used to compare CD to UC. We included 67 patients, 44 (66%) with CD and 23 (34%) with UC. The mean score for IMPACT-III, anxiety, and self-image for CD versus UC was 78 (±SD: 13) versus 78 (±SD: 15), 44 (±SD: 9) versus 45 (±SD: 8), and 10 (±SD: 9) versus 9 (±SD: 6), respectively. We found no difference between CD and UC. Despite remission, we found an elevated score of anxiety and a low score of self-image. When evaluating mental health status, a varied approach may be beneficial for researchers.
