How effective are media-delivered cognitive behavioural therapy and behavioural therapy (self-help therapies) for anxiety disorders in adults?
In general, studies were conducted in high-income, English-speaking countries among white, female, middle-aged participants. These results may not generalise to other settings or participants. Trials had high exclusion rates. Evidence regarding harm was lacking, and economic analyses were beyond the scope of this review. Many of the self-help therapy materials used were intended for research and were not available to the public.
Anxiety disorders are the most common mental health problems. They can be chronic and unremitting. Effective treatments are available, but access to services is limited. Self-help therapies aim to deliver treatment with less input from professionals compared with traditional therapies.
