COGNITIVE THERAPY IN THE TREATMENT OF DRUG-RESISTANT DELUSIONAL DISORDER

Four unselected patients with drug-resistant delusional disorder were individually treated with eight sessions of cognitive therapy plus a b ooster session every month up to 1 year. All patients improved on a gl obal measure of delusional severity (the GSDS), and showed a marked re duction in belief conviction. Related psychopathology as measured on t he Comprehensive Psychopathological Rating Scale (CPRS) also markedly improved and all the gains were maintained at 1-year follow-up. improv ed compliance with medication was achieved with half of the patients, and contributed to the improvement gained.
