Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The proposed intervention is an exposure-based cognitive behavioural therapy adapted for delivery via virtual reality to support social functioning and social cognition in young people recovering from psychosis. The interventional condition within the study is the second version (VR-CBT 2.0) of a previously designed version that has been piloted with young people in a previous related project. In this project, six youth advisors aged 16-30 with lived experience of psychotic symptoms and social challenges were recruited to participate in six online group workshops (2 hours each) and one individual session (14 hours total) over six months. VR-CBT 2.0 will be developed following a user centred design process with a group of lived experience experts as an enhancement to our original version. As part of the intervention, participants will be offered 12 sessions (60 minutes), up to 2 per week, over a maximum of 3-months post baseline. VR-CBT 2.0 will include social cognitive interventions embedded in virtual social environments targeting all four key social cognition domains (1) Emotion recognition (2) Theory of mind, (3) Social perception/knowledge and (4) Attributional biases.

VR-CBT 1.0 & 2.0 will be delivered via virtual reality where the participant will wear the VR headset while the VR clinician will speak to them through the headset and voice some of the avatars within the virtual environment to support young people in developing their social and cognitive functioning skills. Meta Quest 2 headsets will be used to deliver the intervention. The clinical intervention will be administered in one-on-one face-to-face appointments lasting 1-hour. Clinical psychologists who have been trained in delivering the intervention via virtual reality will administer the clinical intervention.

Comparator / control treatment

The original version (VR-CBT 1.0) of an exposure-based VR-CBT intervention that does not include the additional focus on the four domains of social cognition. Participants will be offered 12 sessions (60 minutes), up to 2 per week, over a maximum of 3-months post baseline.

Both therapies are administered by an allied health professional (e.g., psychologist, social worker, psychiatrict nurse, occupational therapist) who has specific qualifications in administering cognitive behavioural therapy. Sessions will include formulating a personal social goal participants want to work on, and the Session Rating Scale (SRS). This is a simple, four-item visual analogue scale designed to assess key dimensions of effective therapeutic relationships.

Summary control condition VR-CBT 1.0:
The first session a personalised case formulation will be built with the participant, including social situations that provoke anxiety, dysfunctional thoughts, feelings, safety behaviours such as avoidance, escape and in-situ avoidance behaviour. It will also include a learning history including life events like bullying, neglect and traumatic experiences. A personal social goal will be formulated. Five minutes will be spent in a pleasant VR-environment to get familiar with the technique. Session 2-11 all follow the same structure. Ten minutes will be spent in talking about relevant events since the last session and in deciding what social environment will be used for exposure today. Then 40 minutes will be spent in a personalised exposure session, working towards the personal social goal (for example talking in front of the classroom) while using the information from the personal case formulation. After that 10 minutes will be used for reflection on the session. The 12th session VR can be used to do a final exposure, but will mostly be set up to establish what was learned from the sessions and how the participant will continue to use the gained knowledge and experience from the therapy.

Statistical methods / analysis
Statistical methods for this project are outlined separately below for Part one and two of the VISOR trial.
(1) Randomised Control Trial (RCT)
Intention to treat analyses will be used to evaluate differences in social functioning between the two treatment groups. Linear mixed-effects regression model will be carried out for repeated measures to evaluate differences in longitudinal trajectories between the two groups to test the hypotheses' that VR-CBT 2.0 is more effective for improving social functioning. This modelling technic both properly accounts for correlations induced by repeated measurements within subjects and produces unbiased estimates with missing observations (when missing at random). The intention-to-treat model will be estimated with (1) treatment group allocation, (2) time, treatment months, as the within-subjects factor, and (3) a group by time interaction to test for differential treatment effects.
(2) Comparison with TAU
Although the effectiveness of VR-CBT 1.0 has been previously demonstrated, we are seeking additional validation in this study by taking advantage of an existing project that collects clinical minimal data from headspace Early Psychosis (hEP) services nationally. Given randomisation will not be conducted we will apply a target trial emulation (Hernán, 2020), which is a state-of-art statistical modelling framework for causal evaluation using observational data. The target trial emulation involves: (1) identifying the control cohort with the same inclusion and exclusion criteria (except for service location); (2) mapping causal pathways between variables collected to identify confounding, mediating or modifying factors using DAGs; and (3) accounting for the impact of these factors using using G-computation and inverse probability-of-treatment weighting (IPTW) to isolate the treatment effect.
(3) Other Secondary Analysis
We will also conduct causal mediation analysis to evaluate whether VR-CBT 2.0 improves treatment responses via enhancing social cognition and reducing safety behaviours. Using the data collected, we will also explore longitudinal dynamic associations between treatment, social cognition, safety behaviours and social functioning using advance statistical modelling, with multilevel structural equation modelling. Factors associated with high treatment response will also be explored using machine learning prediction models. The MDS collected for clinical controls and treatment population will be used to explore a range of outcomes between TAU and the two VR treatment groups, such as general treatment engagement, clinical and functioning outcomes.

Economic evaluation will primarily comprise a cost utility analysis where the main outcome measure is (quality of adjusted life years (QALYs), however primary and secondary outcomes will also be compared to costs differences via a cost-consequence analysis. Two forms of analyses will be undertaken including a standard within trial economic evaluation as well as a population level modelled economic evaluation (including a budget impact analysis). The costs to be considered include the costs of delivering the VR-CBT intervention, other costs determined from the RUQ and linked data. Standardised techniques such as GLM analyses and bootstrapping for uncertainty will be undertaken. If, as expected, the intervention is found to be effective, lifetime and population cost-effectiveness of VRCBT 2.0 will be determined using modelling techniques refined and previously used by co-applicants.

(4) Implementation evaluation
Quantitative data from questionnaires completed by young people and service providers will be analysed using descriptive statistics. Questionnaires completed by service providers will be analysed using repeated measures analysis of variance to assess any changes in acceptability, feasibility and behavioural drivers over time. Qualitative interviews and focus groups will be recorded and transcribed for analysis. Data will be analysed using a Framework Analysis approach, routinely used in implementation research that includes: 1) familiarisation, 2) identifying a thematic framework, 3) indexing, 4) charting, and 5) mapping/interpretation; in the final phase, data can be summarised and organised to identify broad themes of interest and to answer research questions.
Data from the implementation evaluation will be triangulated with data from the main study to examine the relationship between user experiences, acceptability, and engagement with the intervention.
