addressing depression and anxiety symptoms in patients with inflammatory bowel disease

Conditions: Inflammatory Bowel Diseases; Crohn Disease; Ulcerative Colitis; Depression; Anxiety

Summary: inflammatory bowel diseases (ibd) are chronic debilitating disorders of the gastrointestinal tract that comprise two subtypes; crohn's disease (cd) and ulcerative colitis (uc). canada has among the highest incidence rates of cd and uc in the world, as high as 20.2 and 19.5 per 100,000 respectively. although, ibd can occur at any age, it is frequently diagnosed in the second and third decades of life, at a time when vulnerable individuals are entering the prime years of their lives. this age of onset, coupled with the recurrent and frequently relapsing nature of these disorders, can significantly impair the psychological well-being of patients. therefore, it's not surprising that patients with ibd report a higher burden of depression and anxiety in comparison to the general population. the prevalence of depression and anxiety in patients with ibd have previously been linked to the following: (1) increased risk of surgery; (2) increased number of relapses; (3) clinical recurrence; (4) treatment failure and earlier retreatment; (5) lower self-reported quality of life, satisfaction, and medication adherence; (6) and increased health care utilization. although, depression and anxiety are highly treatable conditions, they are often under-recognized and under- treated in patients with ibd. the most common treatments for these disorders are pharmacological agents and psychological treatments. psychological treatments like cognitive behavioral therapy (cbt) have extensive support for treatment of depression and anxiety. the major advantage of psychological treatments over pharmacological agents is their ability to sustain improved depression and anxiety symptoms in patients post-treatment. as part of this study, we aim to evaluate the following: specific aim #1: determine whether a psychological intervention, involving web-based cbt, is effective in ameliorating depression and anxiety symptoms in a cohort of adult ibd patients. specific aim #2: determine the durability effect of the intervention on sustaining improved psychiatric symptoms. specific aim #3: determine the impact of a psychological on ibd-specific and psychiatric-specific health care utilization.
