Eksperimentel: Cognitive Behavior Therapy for Psychosis
Cognitive behavior therapy for psychosis is a manual-driven collaborative talk-therapy designed to help the individual identify appraisal biases and cognitive distortion, identify alternative explanations for events, and find ways to cope with the distress caused by persistent psychotic symptoms.
|
The CBT manual to be used for the present study was based upon the work of Kingdon and Turkington (2005) and Granholm et al., (2005) a group-delivered CBT skills training).
Available manuals were modified to improve ease of training and to better accommodate the delivery of the full CBT treatment in the home environment.
Supervision will be provided throughout the study by D. Turkington and S. Tai world renowned experts in CBT for psychosis.
Training will be held for 1-2 weeks annually and supervision will proceed weekly via SKYPE.
All therapists will be certified prior to providing treatment for the trial.
Sessions are conducted weekly by master's and doctoral level therapists.
