Comparaison of Avatar Therapy to Cognitive Behavioral Therapy in Schizophrenia With Treatment Refractory Hallucinations

Participants will be offered 9 individual and weekly sessions of 1 hour, which will be administered in an individual format by a licensed psychologist or psychiatrist experienced with psychosis patients. The therapy will consist in prompting participants to enter in a dialogue with their persecutor to better regulate their emotional responses. Over the course of the therapy, the avatar's speech and tone will gradually be changed by the therapist to echo participants' improved ability to regulate their emotions. That is, the avatar will progressively change from being abusive to becoming helpful and supportive. By doing so, the therapy will seek to reinforce participants' feeling of empowerment over their voices.

Participants will be offered 9 individual and weekly sessions of 1 hour, which will be administered in an individual format by a licensed psychologist or psychiatrist trained in Cognitive Behavioral Therapy for psychosis (CBTp). The program is derived and adapted from current evidence-based treatments for hallucinations. The 9 CBTp sessions will consist of a succession of learning modules and suggested task assignments.
