ADHD Sympton Checklist-4


Ages: 3 to 18 Years

Completion Time: 5 Minutes

Reading Level: Seventh Grade (Flesch-Kincaid)

The ADHD Symptom Checklist-4 (ADHD-SC4) is a 50-item rating scale for evaluating response to treatment in children and adolescents with AD/HD (ages 3 to 18 years). The same version can be completed by parents and teachers. The ADHD-SC4 comprises four subscales: DSM-5 symptoms of AD/HD; DSM-5 symptoms of oppositional defiant disorder (ODD); the Peer Conflict Scale, which measures interpersonal peer aggression; and the Stimulant Side Effects Checklist (to monitor medication). The ADHD-SC4 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.



ADHD-SC4 Checklists are sold in packages of 50 and 100 checklists. ADHD-SC4 Score Summary Records (diagnostic scoring) are included. The ADHD-SC4 Checklist is available in Spanish and is keyed to the English-language version item-by-item.

ADHD-SC4 Symptom Severity Profile score sheets (dimensional scoring) are sold separately in in packets of 50 each. The Profiles present T scores and corresponding raw scores for each diagnostic category with symptom severity cutoffs. The Profiles present scores for boys and girls and for parent and teacher ratings separately.

The ADHD-SC4 Symptom Checklist-4 Manual reviews DSM diagnostic criteria and describes research about reliability, validity, and treatment sensitivity; normative data; scoring guidelines; and clinical applications for categorical scoring and dimensional scoring.

The ADHD-SC4 Deluxe Kit contains the Manual, 50 ADHD-SC4 Checklists, 50 Summary Score Records (with scoring instructions and cutoff scores), and 50 Symptom Severity Profile (T scores) score sheets.


ASHD-SC4 subscale scores demonstrate satisfactory test-retest reliability, show a high degree of correspondence with psychiatric diagnoses, correlate well with other commonly used dimensional scales and are highly sensitive indicators of treatment effects. Low to moderate correlations between parent and teacher ratings underscore the value of obtaining information from both informants when conducting clinical evaluations. An extensive annotated bibliography of research studies that used at least one Checkmate Plus measure to include the ADHD-SC4 can be accessed on here.


The ADHD-SC4 is scored to derive two different scores:

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

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