Adult version is comprehensive and highly reliable
The CAT-A is a 108-item self-report instrument that is sensitive to the symptomatology of attentional deficits both with and without hyperactivity for adults.
- Consists of two parts: Part 1 (Childhood Memories) assesses the individual’s memories of his or her behaviors and sensations as a child; Part 2 (Current Symptoms) assesses parallel issues in adulthood.
- Clinical index scores are provided for both parts separately and for the summation of the parts.
- Three validity scales—Negative Impression, Infrequency, and Positive Impression—are embedded within the instrument.
- Linkage to DSM-IV™ diagnostic criteria with comprehensive content coverage both within and across scales/clusters assists you in rendering differential diagnoses.
- Context clusters indicate contexts in which ADD/ADHD symptoms are most problematic, whereas locus clusters indicate the extent to which ADD/ADHD symptoms are experienced internally as sensations or experienced as symptoms on which overt behaviors are acted.
Child version allows for multiple perspectives
The CAT-C is a 42-item assessment instrument with three parallel forms: a Self-Rating Form completed by the child or adolescent, a Parent Rating Form completed by one or both parents, and a Teacher Rating Form completed by the child’s or adolescent’s teacher(s).
- Closely resembles the adult version of the CAT. Item content, clinical scales, and clusters are similar and parallel between both forms.
- Standardized on a sample of 800 children and adolescents ages 8-18 years, 800 matched parents of these children, and 500 teachers of these children.
- Concurrent validity, assessed through comparison with the Conners’ Rating Scales, the ADHDT, the CAB™, and the CAD™, revealed moderate-to-high correlations for both nonclinical and combined clinical samples across all three rating forms.
Software portfolio available
The unlimited-use CAT-SP scores and profiles an individual’s performance on the CAT-A or any of the three CAT-C rating forms. After demographic and item response information is hand-entered from a completed rating form, the CAT-SP generates CAT-A and CAT-C score reports.
