Description
The CAS is a multi-informant rating scale that evaluates the setting-specific frequency and severity of aggressive acts in children through parent and teacher rating forms. It facilitates treatment, planning and monitoring in response to acts of aggression. The items describe aggressive acts and are weighted differentially depending on the severity of the act. It is standardized on a community sample of 438 parents and 516 teachers of children ages 5-18 years. Data were also collected on a clinical sample of 247 parents and 252 teachers of children who had been diagnosed with one or more of the following: ADHD, oppositional defiant disorder, conduct disorder, and social maladjustment.
The validity was examined in terms of intercorrelations among the scales and clusters, convergent validity with existing behavioural measures (i.e., BASC-2, CBCL) and domain-specific assessments (i.e., OAS, CDS, IOWA Conners), and clinical validity among the clinical samples.
