Abstract
A 38 year old patient with auditory hallucinations was treated with a brief cognitive-behavioural intervention without concurrent medication. This intervention was based upon the theory of Bentall (1990a, b) and the methods of Haddock, Bentall and Slade (1993). The patient's ratings for frequency of hallucinations and distress caused were significantly reduced at end of treatment, and her belief in the reality of these voices was correspondingly diminished. These gains were maintained at one and three month follow-up.
