- Brief 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.
- Detailed Description
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.

- Primary Outcome Measures
Name Time Method Change in the community functioning performance from baseline to 1-week and 3-months post-intervention (Role Functioning Scale). Participants complete the Role Functioning Scale at baseline, 1-week post-intervention, and 3-months post-intervention. The investigators will measure community functioning through the Role Functioning Scale. Each of the 4 items of the Role Functioning Scale is scored on a scale of 1 to 7. The total score is from 4 to 28 with a higher score indicating a greater community functioning.
Change in social-cognitive performance from baseline to 1-week and 3-months post-intervention (PENN emotion recognition task). Time Frame: Participants complete the PENN emotion recognition task at baseline, 1-week post-intervention, and 3-months post-intervention The investigators will measure the social cognition domain, emotion recognition, using the PENN emotion recognition task. The total score ranges from 0 to 40, with higher scores indicating greater emotion recognition ability.
Change in neurocognitive performance from baseline to 1-week and 3-months post- intervention (Cambridge Automated Neuropsychology Battery). Participants complete the Cambridge Automated Neuropsychology Battery at baseline, 1-week post-intervention, and 3-months post-intervention The investigators will measure neurocognition using nine subtests from the Cambridge Automated Neuropsychology Battery, in which a composite z-score will be computed to represent the cognitive domains measured.
Change in social cognition performance from baseline to 1-week and 3-months post-intervention (Ambiguous Intentions Hostility Questionnaire). Participants complete the Ambiguous Intentions Hostility Questionnaire at baseline, 1-week post-intervention, and 3-months post-intervention The investigators will measure the social cognition domain, attribution bias, using the Ambiguous Intentions Hostility Questionnaire. The Ambiguous Intentions Hostility Questionnaire is rated on a Likert Scale. The total score ranges from 3 to 16, with higher scores indicating greater blame, perceived intention, and anger.
Change in social cognition performance from baseline to 1-week and 3-months post-intervention (The Hinting Task). Participants complete the Hinting Task test at baseline, 1-week post-intervention, and 3 months post-intervention The investigators will measure the social cognition domain, theory of mind, using the The Hinting Task. Each of the 10 items of the Hinting Task is scored on a scale from 0 to 2. The total score ranges from 0 to 20 with higher scores indicating greater theory of mind abilities.
Feasibility of the Intervention (attrition rate). The training completion will be computed at the 1-week post-intervention timepoint. The investigators will measure the feasibility of the intervention by verifying adherence and attrition of participants. The percentage of participants who completed the training program will be computed after the participant completes their final intervention visits.
Feasibility of the intervention (homework completion). Homework completion will be computed at the 1-week post-intervention timepoint. The investigators will measure the feasibility of the intervention by verifying the homework completion by participants. The percentage of homework completion will be computed after the participant completes their final intervention visit.
Change in social cognition performance from baseline to 1-week and 3-months post-intervention (Emotion Regulation Questionnaire). Participants complete the Emotion Regulation Questionnaire test at baseline, 1-week post-intervention, and 3-months post-intervention. The investigators will measure the social cognition domain, emotion regulation, using the Emotion Regulation Questionnaire. Each of the 10 items of the Emotion Recognition Questionnaire is rated on a 7-point Likert scale ranging from 1 ("strongly disagree") to 7 ("strongly agree"). The total score ranges from 10 to 70, with higher scores indicating a greater emotion regulation abilities.
Change in the community functioning performance from baseline to 1-week and 3-months post-intervention (UCSD performance-based skills assessment brief).

- Secondary Outcome Measures
Name Time Method Feasibility of Integrating EMAs into a Clinical Trial The completion of the EMA surveys will be computed at the 6-months post-intervention timepoint. The investigators will assess the feasibility of integrating EMAs into a clinical trial by calculating the overall completion rate of the EMA survey (number of EMA surveys completed divided by the total number of EMA surveys).
Change in the EMA Neurocognition performance from baseline to 1-week and 6-months post-intervention - Jewel task Participants complete the Jewels task through the DigiSensing App at baseline, 1-week post-intervention, and 6-months post-intervention. The investigators will measure neurocognition through the EMA survey using a Jewels Trail test, which is modelled after the Trail Making Test. A greater response time on the Jewels Trail test indicates decreased neurocognitive performance.
