Imagery and psychotic symptoms: a preliminary investigation.

Recent cognitive accounts of psychotic symptoms have suggested that processes involved in the maintenance of emotional disorders may also be implicated in the maintenance of hallucinations and delusions, and particularly emphasise the appraisals of such symptoms as important. Imaginal appraisals have been identified in emotional disorders, and many studies have reported spontaneously occurring images in patients with anxiety disorders. Such images appear to be linked to affect, beliefs and memories. This study examined the occurrence of imagery, using a semi-structured interview, in 35 patients who were experiencing hallucinations and/or delusions and receiving cognitive therapy. The majority of patients (74.3%) reported images, and most of these were recurrent and associated with affect, beliefs and memories. Common themes included images about feared catastrophes associated with paranoia, traumatic memories, and images about the perceived source or content of voices. The theoretical and clinical implications of these findings are discussed and directions for further research considered.
