Computer-delivered cognitive behavioural therapy: effective and getting ready for dissemination

Computer-delivered cognitive behavioural therapy (CCBT) is emerging as a promising strategy for improving access to mental health services. Randomized controlled trials have confirmed the efficacy of guided CCBT in treating depression, generalized anxiety disorder, panic disorder, social phobia, and other common mental disorders. With proper guidance, effect sizes are comparable to those obtained in face-to-face cognitive behavioural therapy, treatment is cost-effective, and preliminary data indicate that CCBT is acceptable to patients. Trials are beginning to evaluate optimal strategies for integrating CCBT within existing systems of mental health care.
