The Aberrant Behavior Checklist (ABC) is a symptom checklist for assessing problem behaviours of children and adults with an intellectual disability at home, in residential facilities and work training centres. It is also useful for classifying problem behaviours of children and adolescents with intellectual disability in educational settings, residential and community-based facilities and developmental centres.
The ABC asks for: degree of intellectual disability, the person’s medical status and current medical condition. Then 58 specific symptoms are rated and an extensive manual provides comprehensive descriptions for each assessed behaviour. 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/Agitation
2. Lethargy/Social Withdrawal
3. Stereotypic Behaviour
4. Hyperactivity/Non-compliance
5. Inappropriate Speech
