The Aberrant Behavior Checklist (ABC) is a symptom checklist for assessing problem behaviors of children and adults with developmental disabilities (intellectual disability, ASD, cerebral palsy, epilepsy). It is also useful for classifying problem behaviors of children and adolescents with developmental disabilities at home,  in educational settings,  community-based facilities, and in developmental centers.

The ABC asks for: Setting where the person was observed and for presence/severity of functional limitations. Then 58 specific symptoms are rated and an extensive manual provides comprehensive descriptions for each assessed behavior. The checklist can be completed by parents, special educators, psychologists, direct caregivers, nurses and others with knowledge of the person being assessed.

The 58 Items Resolve into Five Subscales:

1. Irritability
2. Social Withdrawal
3. Stereotypic Behavior
4. Hyperactivity/Noncompliance
5. Inappropriate Speech

The Aberrant Behavior Checklist now includes combined community and residential manuals, so test administrators have user-friendly normative data for multiple populations, all in one manual.
