      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.
