Case Study

Early treatment for an infant at risk for Autism Spectrum Disorder

Exciting results with the 12- week parent- training program based on the Early Start Denver Model (ESDM)

Introduction
  • Recent advances in early identification of autism symptoms have allowed for intervention with infants as young as 6 months old
  • Using the Infant and Toddler Checklist and the Mullen’s Scale of Early Learning an infant was determined to be at-risk for the development of autism spectrum disorder
  • This study evaluated the change in developmental trajectory using a 12- week parent- training program based on the Early Start Denver Model (ESDM)
Method
  • A collaborative parent coaching method following the Early Start Denver Model (ESDM) was used
  • The clinician met with the mother and child on for 1.5 hours/week for 4 months
  • Parents implemented objectives a minimum 30hrs per week
  • Coaching sessions were done via Skype sessions and in office
  • Skype session: The mother and child were in their own home, the child was either in a high-chair with the mother seated beside, or they were in the living room surrounded by a typical toddler toys, clinician was in a home office.  
  • In office sessions:  The mother and child came to the clinician’s office.  A corner of the office was set up with a mat on the floor and a variety of toddler toys, including blocks, cars, toy animals, puzzles, balloons, bubbles, balls, and cause and effect toys.  The mother, child, and clinician sat together on the mat
  • Individualized objectives were determined using the ESDM Curriculum Checklist for Young Children with Autism
  • Targets comprised of a combination of early social skills, fine motor skills, cognition, imitation, and communication
  • Parents were purchased the book ‘An Early Start for Your Child with Autism’
  • Using the book as a reference, parents and were trained on techniques to increase joint attention and how to implement goals naturalistically in the home environment.
Results

  • The Infant Toddler Checklist revealed a total score in the 4th percentile at 6 months with an increase to the 73rd percentile at the 12- month follow up  
  • Significant improvements were shown in the social composite with a score in the 5th percentile at 6 months with an increase to the 75th percentile at the 12- month follow-up
  • The results of the Mullen Scales of Early Learning showed gains in all areas of development with the exception of gross motor skills

 

Discussion
  • The results of the study support early autism screening for infants and a parent-training model for intervention using principles of applied behavior analysis
  • This study highlights the importance of early screenings for symptoms of ASD so that treatment can begin as early as possible
