Youth's (Self Report) Inventory-4R


Ages: 12 to 18 Years

Completion Time: 10-15 Minutes

Reading Level: Third Grade (Flesch-Kincaid)

The Youth's (Self Report) Inventory-4R (YI-4R) is a behavior rating scale for DSM-IV and DSM-5 emotional and behavioral disorders among adolescents between 12 and 18 years old who are attending middle or secondary school. The YI-4R contains 120 items and includes the symptoms of 18 disorders. Items in the YI-4R correspond to items in the Child and Adolescent Symptom Inventory-5 and the Adolescent Symptom Inventory-4R. 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 YI-4R can be read to the youth by a qualified clinician thus serving as a structured clinical interview. The YI-4R can be scored to derive symptom count scores (based on a diagnostic model) or symptom severity scores (T scores based on a dimensional model). Scoring is quick and easy with user-friendly score sheets. The YI-4R, which was published in 2008, replaces the earlier YI-4.


The YI-4R assesses the symptoms of the following disorders:  *AD/HD  *oppositional defiant disorder  *conduct disorder  *generalized anxiety disorder  *social anxiety disorder  *separation anxiety disorder  *major depressive disorder  *persistent depressive mood  *bipolar disorder  *schizophrenia  *schizoid personality disorder  *anorexia nervosa  *bulimia  *substance use. There are one or two key symptoms of each of the following disorders:  *specific phobia  *panic disorder  *obsessive-compulsive disorder  *adjustment disorder  *acute stress disorder  *motor tics  *vocal tics  *somatic symptom disorder.


YI-4R checklists are sold in packages of 50 checklists. YI-4R Symptom Count Cutoff score sheets (categorical model) are included. The YI-4 Checklist is available in Spanish and is keyed to the English-language version item-by-item.

YI-4R Symptom Severity Profile score sheets (dimensional model) can be purchased for the YI-4R Checklist. The Profiles present T scores and corresponding raw scores for each diagnostic category with symptom severity cutoffs.

The Youth’s Inventory-4 Manual reviews DSM diagnostic criteria and describes research, scoring guidelines, normative data, and clinical applications for symptom count (categorical) and symptom severity (dimensional) scores.

The YI Deluxe Kit contains the YI Manual, 50 YI Checklists, 50 symptom count score sheets, and 50 symptom severity profile score sheets.


YI-4R subscale scores demonstrate satisfactory test-retest reliability, show a high degree of correspondence with psychiatric diagnoses, and correlate well with other commonly used dimensional scales. Low to moderate correlations of youth ratings with parent and teacher ratings underscore the value of obtaining information from all relevant informants when conducting clinical evaluations. An extensive annotated bibliography of research studies that used at least one Checkmate Plus assessment tool to include the YI-4R can be accessed here.


The YI-4R can be scored to derive four different scores (also see Scoring):

  • Symptom Count Cutoff scores based on the number of symptoms necessary for DSM diagnoses,

  • Symptom Severity scores based on a dimensional model that uses normative data to generate T scores,

  • Impairment Cutoff scores indicate whether youth is impaired by the symptoms of a specific disorder, and

  • Clinical Cutoff scores which are a combination of the Symptom Count Cutoff score and the Impairment Cutoff score.
