Review: some evidence shows that self help books based on cognitive behaviour therapy can relieve depression in some patients

Study selection and assessment: randomised controlled trials (RCTs) that evaluated self help books for patients with depression who were .16 years of age, with or without anxiety. The intervention included written material given with minimal guidance (defined as (1 h professional face to face time, or up to six 15 min telephone calls). Each study was assessed for adequacy of random allocation concealment; follow up; statement of primary outcome measure; and a priori power calculation.
