The study instruments included: the Self-Help Skills Developmental Chart and the Gilliam Autism Rating Scale that were administered at both pretest and posttest. The experimental group received an ABA intervention for 20 sessions (each session: 2 hours) over 3 months. Data analysis was done using IBM SPSS Statistics for Windows, Version 22.0.
