Parent Training for Disruptive Behaviors in Referred Children with Autism Spectrum Disorder: A Randomized Controlled...

The purpose of this study was to investigate whether face-to-face and therapist-assisted online (i.e., blended) behavioral parent training are effective on reducing disruptive behaviors in children with autism spectrum disorder (ASD) in routine mental health care. Ninety-seven children with ASD (4-13 years; 76 boys) were randomized to face-to-face parent training, blended parent training, or a waitlist control condition. We assessed treatment effects on parent-rated child noncompliance (primary outcome) and irritability (secondary outcome). This involved comparing both formats separately to the control condition using linear regression models. Child behaviors at 6 months follow-up were also examined. Children in the face-to-face parent training condition improved significantly more on noncompliance and irritability than children in the waitlist condition and improvements sustained to 6 months follow-up. Children in the blended condition did not improve more than children in the waitlist condition and attrition was high. Our results extend findings from efficacy studies to routine mental health care and advocate the use of face-to-face parent training for disruptive behaviors in children with ASD. More research into blended parent training programs for children with ASD and disruptive behaviors in routine mental health care should be conducted to draw more definite conclusions about the value of blended parent training for these children.
