Evaluating Overall Functioning Across Adaptive Domains in Children with Autism Spectrum Disorder: Implementation and Application of the Developmental Disabilities Modification of the Children's Global Assessment Scale (DD-CGAS)

Abstract

This practicum, completed at HANDS in Autism® in collaboration with the Indiana NeuroDiagnostic Institute (NDI), focused on evaluating overall functioning in adolescents with Autism Spectrum Disorder (ASD) using the Developmental Disabilities Modification of the Children's Global Assessment Scale (DD-CGAS). The study analyzed data from 58 patients across the pre-admission and post-discharge phases, with ratings assigned in key adaptive domains: Self-Care, Communication, Social Behavior, and School/Academic Functioning. Additional measures included Eating, Sleeping, and Dressing abilities. Data were extracted from the Cerner electronic health record system, cleaned and coded using REDCap, and analyzed using Python, Excel, and Power BI. By comparing DD-CGAS scores across age and gender groups, the project assessed the impact of integrated, patient-centered inpatient care on behavioral functioning. Findings support the utility of structured, quantitative behavioral assessments in improving treatment planning and measuring intervention outcomes in ASD-focused psychiatric settings.
