简要总结
The purpose of the present study is to examine whether cognitive behavior therapy will reduce depressive symptoms and increase self-esteem for patients with a first episode psychosis.
详细描述
A growing body of evidence supports the use of Cognitive Behavioural Therapy (CBT) for the treatment of schizophrenia. The strength of evidence is especially strong for patients with persistent hallucinations and delusions. As it comes to the effect of CBT for patients with a first episode psychosis the picture is more unclear. The main reason is probably that the CBT interventions to a less extent have been adjusted to fit first episode psychosis patients. The main problems for patients with a first episode psychosis (FEP) is rarely persistent hallucinations and delusions but they struggle with social anxiety, depression, alcohol and drug abuse and low self esteem. Forthcoming studies examining the effect of CBT for patients with a first episode psychosis should aim to have a focus on these symptoms.
The main aim of the present study is to examine whether CBT has any effect on depressive symptoms and self-esteem in patients with a FEP.
The study will include patients with a first episode psychosis with Axis-I DSM IV diagnosis of schizophrenia, schizoaffective disorder, delusional disorder, and psychosis not otherwise specified. To be included in the study the patients should meet the criteria of an affective episode the last year or have a score on Calgary Depression of Schizophrenia Scale above four. Patients are randomly selected to either a treatment group or a control (placebo) group. The aim is to include 30 patients in each group. Patients in the treatment group will receive a manual-based CBT intervention comprising up to 26 sessions during a six months period. The control group will receive treatment as usual (TAU).
The patients are assessed before the entry of the study and after 6 months (end of treatment). Moreover they will be assessed after 9 months of ending therapy.
