A longitudinal analysis of an ABA program’s effects on adaptive behavior, autism spectrum symptoms, and language in school-age children
This study investigated the effects of an ABA treatment over time on several variables, including adaptive behavior, symptoms of Autism Spectrum Disorders (ASDs), and communication competencies. In regards to adaptive behavior, caregivers reported that expressive language, written language, and community skills decreased with time; teachers reported that children’s play and leisure skills, coping skills, and socialization skills increased over time. Mental health professionals reported that ASD symptoms decreased with time. Auditory and expressive comprehension scores increased with time as reported by the child’s speech-language pathologist. Overall, results suggest that while the targeted skills are mostly changing in the expected direction as reported by school personnel, these changes may not be generalizing to the home environment.
