Abstract:
OBJECTIVE: The effect of cognitive-behavioral therapy on the delusion in schizophrenic patients was evaluated. METHOD: The patients admitted to a psychiatric ward from September 1999 to June 2000 and diagnosed as schizophrenia, schizophreniform disorder, and schizoaffective disorder by DSM-IV were randomly assigned to cognitive-behavioral therapy(CBT) group(n=9) and supportive psychotherapy (ST) group(n=8). During the 10 weeks' treatment period, conviction, preoccupation, and anxiety on delusion, mode of explanation about symptom, and recovery style were regularly measured and compared between groups. RESULTS: 1) As for conviction and anxiety on delusion, the patients from both groups showed gradual reduction over time, but there was no significant difference between groups. 2) As for preoccupation of delusion, patients from both groups showed gradual reduction over time, and the patients on CBT group had a significantly more reduction than ST group. 3) As for mode of explanation and recovery style, CBT group had more marked positive changes than ST group did. CONCLUSION: Cognitive-behavioral therapy is more effective on preoccupation of delusion, explanatory mode about symptom, and recovery style than supportive psychotherapy.
