Telephone administered cognitive behaviour therapy for treatment of obsessive compulsive disorder: randomised controlled non-inferiority trial.

Objectives: To compare the effectiveness of cognitive behaviour therapy delivered by telephone with the same therapy given face to face in the treatment of obsessive compulsive disorder.

Design: Randomised controlled non-inferiority trial.

Setting: Two psychology outpatient departments in the United Kingdom.

Agoraphobia: nurse therapist-facilitated self-help manual.

Background: Agoraphobia is a common and disabling mental health disorder. Substantial evidence supports the use of cognitive behaviour therapy (CBT), in particular the intervention termed exposure therapy, as the treatment of choice. However, although the evidence base for cognitive-behaviour therapy is extensive, the service delivery evidence base is poor, and alternative ways of delivering therapy are required if mental health services are to achieve standards set out by the National Service Framework in the United Kingdom.
