Abstract
Objectives
Cognitive behavioral therapy for treatment of schizophrenia was designed as a psychological therapy for treatment of drug resistant patients with schizophrenia. This therapy is currently being widely applied from early psychosis to chronic condition. The aim of this article is to review the main results of research articles on cognitive behavioral therapy of schizophrenia and prompt practicing the therapy in Korean mental health services.
Methods
The important original and review articles were referred in order to understand the main results of research from published international books, and the English website Pubmed was searched in order to update recent findings. This article reviewed the results of four areas of different phases and types of cognitive behavioral therapy for treatment of schizophrenia: drug resistant chronic patients, acute psychotic state, prodromal phase, and group cognitive behavioral therapy.
Results
Cognitive behavioral therapy for treatment of drug resistant patients with schizophrenia can attenuate the positive and general symptoms more than that for patients who receive supportive psychotherapy or treatment as usual. However, the effect appears to be less than previously expected, small to moderate. Cognitive behavioral therapy for patients of acute psychotic state can reduce the time of recovery from acute psychotic symptoms by approximately 25%. The result of cognitive behavioral therapy for patients of prodromal phase shows that the therapy can reduce the rate of transition to schizophrenia by up to one third. Group behavioral therapy has recently been tested. Group therapists have suggested that the therapy should be applied through the way of groups with relatively homogenous symptoms. However, whether the therapy can reduce the severity of hallucination in the voice hearer group is inconclusive.
Conclusion
Alongside pharmacotherapy for treatment of schizophrenia, cognitive behavioral therapy is a distinct psychological therapy for attenuation of psychotic symptoms. The effect of cognitive behavioral therapy appears to last for one year and requires additional therapeutic sessions after one year. The effect is not still clear in group cognitive behavioral therapy for treatment of schizophrenia. Cognitive behavioral therapy for treatment of schizophrenia should be practiced widely in the Korean mental health system.
