Cognitive-behavioural approaches in the treatment of hypochondriasis: six single case cross-over studies.

This study evaluates a cognitive and a behavioural treatment protocol for hypochondrical complaints. In a cross-over design, six patients with a primary diagnosis of hypochondriasis were treated. Three of them first received a block of behavioural therapy (exposure in vivo and response prevention), followed by a block of cognitive therapy. The other three patients were first treated with cognitive therapy followed by behavioural therapy. The results were promising: four patients made significant improvements. The behavioural therapy sessions appeared to account more often for improvement than did the cognitive sessions. The sequence of behavioural therapy followed by cognitive therapy tended to be more successful than the other way around. The results of these six case studies suggest that exposure in vivo with response prevention and cognitive therapy may both be useful in the treatment of hypochondriasis. A journal controlled study is recommended.
