Effectiveness of HRV Biofeedback in Decreasing Anger Among Adolescents With Autism Spectrum Disorder

This study investigates the use of heart rate variability (HRV) biofeedback to manage anger in autistic adolescents.Anger, a natural but potentially maladaptive response to stress, is particularly prevalent among adolescents and is compounded for those on the autism spectrum due to difficulties with sensory processing and communication.Previous research suggests that biofeedback is a promising tool for managing anger.This study examines the effects of HRV biofeedback, both alone and in combination with de-escalation techniques, on reducing anger frequency and intensity among three autistic adolescents.Results show a significant decrease in both anger episodes and intensity during the HRV biofeedback condition, with further reductions observed when de-escalation strategies were added.These improvements were maintained during a 6-month follow-up, indicating the potential for long-term benefits.The study suggests that HRV biofeedback, especially when paired with cognitive-behavioral strategies, may offer an effective, noninvasive, and sustainable approach to anger management for autistic adolescents.
