The Child & Adolescent Symptom Inventory-5 (CASI-5) is a behavior rating scale for evaluating the symptoms of DSM-5 emotional and behavioral disorders among children and adolescents between 5 and 18 years old who are attending elementary, middle, or secondary school. There are both parent- and teacher-completed versions. The CASI-5: Parent Checklist contains 173 items for over two dozen emotional and behavioral disorders, and the CASI-5: Teacher Checklist contains 125 items. For each multi-item disorder there is an impairment question (i.e., the degree to which symptoms interfere with the youth’s social or academic functioning). The CASI-5 can be read to the parent by a qualified clinician thus serving as a structured clinical interview. The CASI-5 can be scored to derive symptom count cutoff scores (diagnostic model) or symptom severity scores (T scores based on a dimensional model). Scoring is quick and easy with user-friendly score sheets. The CASI-5 replaces the CASI-4R.
