Psychotherapy for Psychosis, Adverse Events, and Substance Misuse

The intervention will be adapted prolonged exposure therapy, called PE+ therapy. Participants will receive 15 weekly 90-minute sessions of PE+; these appointments will be divided into five sets of three sessions each: 1) psychoeducation about AEs, SM, and the interplay of both with psychosis; 2) emotion regulation strategies; 3) imaginal exposures, 4) in vivo exposures, and 5) review of treatment and planning for termination and maintenance.

The intervention will be antipsychotics prescribed by clinicians working within the Nova Scotia Early Psychosis Program (NSEPP) as well as case management supplied by their primary nurse. Program participants will have access to educational programs about psychosis, skills/vocational training, as well as familial education and support.
