The majority of inpatients at Parkwood Institute Mental Health have symptoms of psychosis. In line with Health Quality Ontario standards for the treatment of psychosis, the investigators would like to implement and evaluate cognitive behavioural therapy for psychosis (CBTp) informed groups. The feasibility, acceptability, and preliminary efficacy of CBTp groups for inpatients will be examined. Pragmatically, the investigators propose to undergo training in CBTp, implement empirically-supported CBTp protocols developed for inpatients, track outcomes, and publish our findings. The investigators would also incorporate patient feedback to improve future iterations of the protocol. Such an undertaking would build research capacity in front line staff by encouraging engagement in CBTp group training, survey design, participant screening, data collection, analyses, and dissemination of findings.
