Depression and anxiety are prevalent and disabling conditions that often go untreated. Internet-delivered Cognitive Behaviour Therapy (ICBT) is a relatively new approach to treatment that is a convenient way for patients to access care. ICBT is typically highly standardized and involves patients reviewing weekly lessons over the Internet. Patients also receive brief weekly support from a therapist via secure emails or phone calls. Past research shows that ~75% of patients complete ICBT and report large symptom improvements. Although these results are very promising, research also suggests that ICBT could potentially be improved by being more personalized in terms of amount of therapist contact, especially for clients with more severe symptoms. The current trial will involve therapists who work in a clinic that specializes in ICBT. Over one year, 440 patients with depression and/or anxiety will be randomized to either receive standardized (5 lessons completed in 8 weeks; once week therapist contact) or personalized ICBT (5 lessons completed in 8 weeks; personalized therapist contact depending on needs of patient). Psychosocial outcomes of patients in the two treatment arms will be compared post-treatment and at 3-month, 6-month, and 1-year follow-up from enrollment. Data on intervention usage, satisfaction measures, and costs will also be assessed.
