YOUTH'S INVENTORY-4 (YI-4)
Ages 12 To 18 years old
By Kenneth D. Gadow, Ph.D., and Joyce Sprafkin, Ph.D.
The Youth's Inventory-4 (YI-4) is a self-report
rating scale that helps to evaluate DSM-IV emotional and behavioral
disorders in youths between 12 and 18 years old. Responses to the YI-4 can
provide valuable insight into the youth's perceptions of his or her problems.
The YI-4 contains 120 items that correspond to those in the Adolescent Symptom
Inventory-4 and includes the symptoms of 18 disorders. The YI-4 can be
scored to derive Symptom Count scores (diagnostic model) or Symptom Severity
scores (normative data model). Scoring is quick and easy with
user-friendly score sheets.
