Using Virtual Reality to Treat Social Anxiety in Autistic Adolescents
Using Virtual Reality Assisted Therapy for Social Anxiety in Adolescents With Autism Spectrum Disorder: A Case Series
Study Overview

Intervention / Treatment
Detailed Description
Difficulties interacting with others in social situations is a core characteristic of autism spectrum disorder (ASD). These difficulties are intensified by social anxiety - commonly experienced in autistic adolescents. A promising psychological treatment is cognitive behavioural therapy (CBT), but there are constraints in its use for the autistic population. For example, CBT requires patients to imagine being in a social situation that would cause anxiety, but autistic people often experience difficulties with imagination. The use of virtual reality (VR) in CBT may help to lessen such constraints. VR uses 3D computer-generated visual environments displayed through a head-mounted display. The images are synchronised to the movements of the user such that they experience feeling immersed in the virtual scene. The virtual scene can involve social scenarios, making it an ideal tool for eliciting social anxiety in the treatment setting. The investigators can see if these virtual scenarios are indeed eliciting social anxiety by recording physiological responses (e.g. heart rate) in parallel with patients' anxiety ratings during exposure. This is important for CBT to be effective.
This study will test the feasibility and acceptability of VR-assisted CBT, combined with the use of physiological measurements, in autistic adolescents experiencing social anxiety. The therapy will typically consist of 8-20 weekly sessions and will be delivered by clinical psychologists in local mental health services. Conventional outcome measures will be used and feedback from youth and their parents/caregivers will be requested. The results of this study may lead to modification of the treatment and research methods. They will inform a later pilot randomised controlled trial.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Virtual Reality Assisted Cognitive Behavioural Therapy
Between 8 to 20 individual in-person sessions of VR-assisted CBT will be delivered on a weekly basis by NHS therapists who are trained in delivering CBT to this patient group.
|
The intervention will be delivered in NHS services and will involve using VR to assist the delivery of conventional CBT for the treatment of social anxiety in autistic adolescents.
Social situations that are commonly anxiety-evoking for this patient group will be simulated in VR and used for exposure (a typical component of CBT for social anxiety).
Therapists will use a modular approach involving optional modules such as psychoeducation on anxiety in the context of ASD, managing expectations of outcome and emotional literacy training.
Essential modules include rapport building, introducing the use and purpose of VR, and exposure (incorporating VR).
Because CBT is delivered in routine clinical practice, the VR exposure sessions will be the main subject of interest.

This is a 25-item self-report questionnaire.
Participants are asked to rate the extent they agree with each statement using a 5-point Likert scale (0 = Not at all; 4 = Very much).
Statements refer to their experience of the therapy and whether taking part has caused any distress.
Higher scores indicate increased adverse effects.

|
Qualitative feedback regarding the intervention will be sought from therapists and participants using a semi-structured interview.
The interview will follow a topic guide aimed at understanding opinions on helpful aspects of the therapy, suggestions for improvement, and the perceived level of social presence (i.e. the subjective experience of being with the non-player characters) in the VR environments.
Feedback will be summarised.

This will be measured using Goal Attainment Scaling (GAS).
Goals are agreed at the start of therapy.
Initially patients rate the importance, difficulty, and how they are functioning at baseline, for each goal.
After therapy patients indicate whether the goal has been achieved and rate the outcome (e.g.
+2 better than expected, -2 worse than expected).

Time Frame: Baseline; end of therapy up to 20 weeks; follow-up: 6 weeks post-treatment.
|
Measured using the Revised Children's Anxiety and Depression Scale (and Subscales) (RCADS; Chorpita et al. 2000).
This is a 47-item self-report questionnaire.
Both youth (suitable for ages 8 to 18 years) and parental/caregiver forms will be administered.
Participants rate each item using a 4-point Likert scale (0 = Never; 3 = Always).
The questionnaires are scored using spreadsheets provided by the developer.
A t-score is computed based on the person's school year.
T-scores of 70 and higher are classified as clinically significant.
Higher t-scores indicate increased symptoms.
|
Baseline; end of therapy up to 20 weeks; follow-up: 6 weeks post-treatment.
|
Change in Global Outcome Ratings of Severity of Illness.
Time Frame: Baseline; end of therapy up to 20 weeks; follow-up: 6 weeks post-treatment.
|
Measured using the Clinical Global Impression-Improvement Scale (CGI-I; Guy, 1976). At baseline, the researcher will rate their "impression" of illness severity using baseline qualitative data from the Anxiety Disorders Interview Schedule (ADIS-IV; Albano & Silverman, 1996) on a 7-point Likert scale (1 = normal, not ill at all; 7 = among the most severely ill patients). The ADIS-IV is a semi-structured clinical interview which will be conducted separately with patients and their parents/caregivers (informants). The same researcher will compare baseline ADIS-IV data with data obtained from a follow-up (qualitative) interview to rate "improvement". The follow-up interview will be semi-structured, follow a topic guide, and be conducted with the patient and their parent/caregiver (informants) separately. Topics will cover functioning across activities of daily living. "Improvement" will be rated on an 8-point Likert scale (1 = completely recovered; 5 = no change; 8 = very much worse). |
