examining the efficacy of a virtual reality cognitive remediation program for people living with psychosis

Conditions: Psychotic Disorders; Schizophrenia; Schizo Affective Disorder

Summary: individuals living with a psychotic disorder often experience changes to their thinking and social skills that can lead to challenges with work, school, relationships and living independently. one intervention to target these areas is cognitive remediation therapy, which can be delivered in virtual reality to help apply the skills and strategies learned to day-to-day life. over the past few years, our team has co-developed a cognitive remediation program in virtual reality with healthcare professionals and people with lived experiences of psychosis. the current trial tests the feasibility and efficacy of this cognitive remediation program in virtual reality at improving thinking skills, social skills, and daily life functioning.

eligible participants will be administered various clinical (including a module from the mini international neuropsychiatric interview and the wechsler abbreviated scale intelligence (wasi) to confirm eligibility), neurocognitive, social-cognitive, and community functioning assessments across two baseline visits. participants are then randomly assigned to one of two study arms (a cognitive remediation intervention and active control, both using virtual reality). regardless of the study arm assignment, participants will complete a six weeks (12 visits) training program where they will complete exercises in virtual reality and converse with study staff about a pre-selected topic. after each training visits, participants will also complete short questionnaires about their experience. one-week and three-months post-intervention, participants will complete the same assessments administered during the baseline visits. also, at the one-week post-intervention time point, participants will complete a satisfaction with cognitive remediation program questionnaire. the investigators will also use ecological momentary assessments (emas) delivered through a smartphone app to measure changes in thinking skills and daily life functioning within the context of this clinical trial. at the first visit, the investigators will invite participants to download the ema app, digisensing, to their phone. digisensing is built from the open access mindlamp app, which has been used to measure neurocognition in previous studies. through the digisensing app, the investigators will deliver three, ten-minute assessments at baseline, one-week post-intervention, and six-months post-intervention. each assessment has thinking skill tasks, and questions about mood, clinical symptoms, thinking skills, and daily life functioning.
