The study involved 78 preschool children diagnosed with ASD who were randomized to receive either a 20-week intervention combining Virtual Reality–Incorporated Cognitive Behavioral Therapy (VR-CBT) and Learning Style Profile (LSP) training or LSP training alone. The primary outcome measured was the change in Autism Behavior Checklist (ABC) scores from baseline to week 20, while secondary outcomes included the Childhood Autism Rating Scale (CARS) and behavioral performance data in go/no-go tasks.
Key Findings
- Significant improvements in total ABC and CARS scores were observed in the intervention group compared to the control group.
- The intervention group showed notable enhancements in sensory, relating, body and object use, and social and self-help subscales of the ABC.
- Improved accuracy in go/no-go tasks, indicating better response inhibition.
- Reduction in ADHD hyperactivity-impulsivity symptoms among children with comorbid ADHD.
These findings underscore the potential of VR-CBT as an effective adjunctive digital tool for addressing core symptoms of ASD, such as social skill impairments and repetitive behaviors. The use of a nonwearable VR platform ensures that preschoolers, who may find wearable devices cumbersome, can still benefit from immersive, interactive therapeutic environments.
Practical Implications for Practitioners
For practitioners working with preschoolers with ASD, integrating nonwearable digital therapeutic interventions like VR-CBT can be a game-changer. Here are some steps to consider:
- Evaluate Suitability: Assess whether VR-CBT is appropriate for each child based on their specific needs and learning styles.
- Incorporate Gradually: Introduce VR-CBT sessions gradually, starting with shorter durations and increasing as the child becomes more comfortable.
- Combine with Traditional Methods: Use VR-CBT as an adjunct to traditional therapies like speech and occupational therapy for a holistic approach.
- Monitor Progress: Regularly track the child's progress using standardized tools like the ABC and CARS to adjust the intervention as needed.
- Engage Parents: Involve parents in the process, providing them with guidance on how to support their child's therapy at home.
Encouraging Further Research
While this study provides robust evidence for the efficacy of nonwearable digital therapeutic interventions, more research is needed to explore long-term outcomes and the applicability to broader populations, including children with lower IQs or other comorbid conditions. Practitioners are encouraged to participate in or support ongoing research efforts to refine and expand these innovative therapeutic approaches.
