Applied Behavior Analysis to Treat Toddlers With Autism Spectrum Disorder
Applied Behavior Analysis can successfully be used to treat children below 3 years with a diagnosis of Autistic Disorder, PDDNOS or related behavior disorders. Analyses of data from 93 children who received an average of nine months of treatment with Applied Behavior Analysis showed that most of the children improved on a majority of the 9 Scales of the ABLLS-R. Further results indicated that treatment beginning at a younger age was most successful.
Applied Behavior Analysis (ABA) has been an accepted form of behavioral treatment for individuals with Autism Spectrum Disorder (ASD) (Anderson S.R. & Romanczyk, 1999).
Furthermore, ABA has been effective in treating ASD in children aged over 3.
However, early intervention for children 3 and under has had limited empirical evidence.
The present study aims at clarifying how toddlers respond to a center-based ABA program for 2½ hours per day, 5 days a week.
Toddlers were evaluated by licensed psychologists who determined eligibility for EI, Center-based ABA & ASD diagnosis
31 toddlers placed in a center-based ABA program completed an average of 8.86 months.
Toddlers were evaluated with ABLLS-R (Assessment of Basic Language and Learning Skills – Revised) pre & post treatment.
Toddlers were instructed in their own language: Chinese (42%) [Cantonese/Mandarin], Spanish(19%) English(32%), Other(3%).Requests
All students increased on all 9 ABLLS-R scales
Average group increase for ABLLS-R scales was statistically significant
High initial Imitation predicted high labeling and intraverbals
Improvement in Imitation predicted high Receptive language and Requests
Children >36 months increased more than children <34 months
Only true for 9 scales
Results indicate that 12.5 hours/ week of center-based ABA for toddlers aged 3 and under is successful in treating ASD, according to ABBLS-R scoring.
Further longitudinal study is warranted in order to track how early intervention affects toddlers in the long term (i.e. does ABA experience in Early Intervention services permit the child to be in inclusion classes?).
