Immersive Virtual Reality for Social Skills Training in Children with Autism Spectrum Disorder: A Pilot Study in School-Based Simulated Contexts

The present pilot study examined the feasibility, acceptability, and preliminary effectiveness of a VR-based social skills intervention for children with Autism Spectrum Disorder (ASD). Five participants aged 7–17 years participated in a six-session intervention protocol, with each session lasting approximately 45 min. The study employed a randomized AB/BA crossover design, in which participants completed two sessions under an Active condition involving instructional prompts, corrective feedback, and positive reinforcement, and two sessions under a Neutral condition without prompts or reinforcement. Following the intervention phases, participants completed a Generalization session in a novel virtual environment and a Follow-up session to assess skill retention over time. The intervention incorporated two interactive VR scenarios: (a) a simulated classroom environment, where a teacher-avatar engaged participants in structured question-and-answer activities, and (b) a virtual school playground, where participants interacted with peer avatars in social communication tasks designed to promote conversational engagement, turn-taking, and social reciprocity. All avatar interactions and trial progressions were controlled by the therapist through a dedicated monitoring interface, ensuring standardized implementation across participants. Evaluation was based on qualitative observation, analysis of recorded video material, and brief post-intervention parent interviews. Preliminary findings suggest that the intervention was feasible, well accepted by participants, and associated with improvements in social communication performance, supporting the potential of VR as a complementary tool for social skills training in children with ASD.
