Early Intervention and ABA-Based Therapeutic Outcomes in a Child with Mild Autism Spectrum Disorder: A Comprehensive Case Study

Abstract

This case study presents the developmental profile and therapeutic progress of XYZ, a female child diagnosed with mild ASD at the age of two years. The study documents her developmental concerns, early intervention history, and subsequent enrollment at a therapy center following family relocation. A comprehensive five-day observation and multi-domain assessment revealed challenges in eye contact, attention, expressive language, articulation, behavior regulation, and sensory processing.A three-month ABA-aligned intervention plan was implemented, focusing on skill development, speech and language enhancement, social interaction, and emotionalbehavioral regulation. Supplementary strategies, such as park-based tasks, functional home activities, peer-pairing, and reinforcement systems, further facilitated her growth. Significant improvements were observed across expressive communication, emotional stability, attention span, social adaptability, and articulatory accuracy. Over the course of one year, XYZ achieved age-appropriate developmental and behavioral functioning. She now demonstrates strong academic and co-curricular performance, with no major developmental concerns. The case highlights the importance of early intervention, consistent parental involvement, and individualized ABA-based therapy for favorable outcomes in children with mild ASD.
