aberrant behavior checklist
Also written as: ABC — Aberrant Behavior Checklist
A standardized assessment tool measuring problem behaviors in individuals with developmental disabilities across multiple domains.
Full Definition
A widely used rating scale designed to assess the frequency and severity of problem behaviors in individuals with intellectual and developmental disabilities. The checklist typically includes subscales for irritability, lethargy, stereotypy, hyperactivity, and inappropriate speech. Originally developed for use in pharmacological research, it has become a standard outcome measure in behavioral intervention studies and clinical practice. The tool provides quantifiable data for treatment planning and progress monitoring, making it valuable for both research and clinical applications in developmental disability services.
Usage
Usage note: Often abbreviated as ABC, but distinguish from 'antecedent-behavior-consequence' which uses the same acronym in different contexts.
