Effect of ESDM and PCIT-A in Autism Spectrum Disorder — TAFF  

Autism Spectrum Disorder Clinical Trial

Official title: Effect of Early Start Denver Model and Autism-adapted Parent-Child Interaction Therapy on Autism Symptoms and Disruptive Behavior in Toddlers and Preschool Children With Autism Spectrum Disorder (TAFF Pilot Study)

Status Recruiting

Clinical Trial Summary

Children with ASD often show disruptive behaviors. However, interventions that were specifically designed to improve these symptoms have not been sufficiently investigated, especially in children with level 1 to level 3 ASD. PCIT has large effects on externalizing behavior problems in children with disruptive behavior disorders. Recently PCIT was adapted for children with autism spectrum disorder (PCIT-A). ESDM is an evidence-based treatment for ASD but has not been investigated in combination with PCIT-A.

As primary aims, the investigators assess a) the effect of PCIT-A on disruptive behavior and b) the effect of ESDM on autism symptoms in toddlers and preschool children with ASD level 1 to 3. As secondary aims, the investigators evaluate a) the maintenance of the effect of PCIT-A one year after the end of intervention and b) the effect of both interventions on secondary outcomes (developmental level, intelligence, adaptive behavior, and parenting stress), c) the combined intervention effect of PCIT-A and ESDM depending on intervention overlap periods.

Clinical Trial Description

Autism spectrum disorder (ASD) is a life-long neurodevelopmental disorder with recognizable symptoms often beginning between one and two years of age and an estimated prevalence of about 0.6%. Both social communication deficits, and restrictive and repetitive behavior depict the core symptoms of ASD.

ESDM is an evidence-based treatment for ASD. A recent meta-analysis comprising 12 studies show favorable effects of ESDM on cognition and language with a moderate effect size, in contrast to control groups. ESDM showed to become cost-efficient within a few years after treatment as a result of less use of other health care services in the years following the intervention.

Children with ASD often show disruptive behaviors such as angry outbursts, irritability, aggressive and oppositional behaviors. However, interventions that were specifically designed to improve these symptoms have not been sufficiently investigated, especially in children with level 1 to level 3 ASD. PCIT has large effects on externalizing behavior problems in children with disruptive behavior disorders. Recently, PCIT was adapted for children with autism spectrum disorder (PCIT-A).

As primary aims of the so-called TAFF (Tagesklinik für Autismus und Frühförderung [Day Clinic for Autism and Early Intervention]) pilot study, the investigators assess a) the effect of PCIT-A on disruptive behavior and b) the effect of ESDM on autism symptoms in toddlers and preschool children with ASD level 1 to 3. As secondary aims, the investigators evaluate a) the maintenance of the effect of PCIT-A one year after the end of intervention and b) the effect of both interventions on secondary outcomes (developmental level, intelligence, adaptive behavior, and parenting stress), c) the combined intervention effect of PCIT-A and ESDM depending on intervention overlap periods. ;
