SECONDARY
ABC, a secondary rating scale, was originally developed to assess the effectiveness of psychotropic medication and measures the severity of a range of behaviour problems across five subscales. At each follow-up, parents/caregivers evaluated subdomains as follows: irritability, lethargy/social withdrawal, stereotypic behaviour, hyperactivity/noncompliance, and inappropriate speech. Summary scores were used for psychometric analysis.
