Longitudinal Behavioral Trend Analysis Using the Aberrant Behavior Checklist in Individuals With Developmental Disabilities

Abstract

This project aimed at analyzing behavioral changes in individuals with developmental disabilities over time, utilizing the Aberrant Behavior Checklist (ABC). Data were collected at six timepoints ranging from pre-admission to 12 months post-discharge. The analysis focused on five key behavioral subscales: irritability, social withdrawal, stereotypic behavior, hyperactivity/noncompliance, and inappropriate speech. Results indicated the greatest improvements in stereotypic behavior and irritability, while social withdrawal and inappropriate speech showed only modest progress, suggesting a need for more targeted interventions. Power BI was employed to clean, visualize, and track behavioral trends, facilitating data-driven insights and recommendations for enhancing intervention strategies. The findings highlight the importance of flexible, individualized support plans in optimizing behavioral outcomes.
