ADHD Symptom Checklist-4 (ADHD-SC4)

by Kenneth D. Gadow, Ph.D., and Joyce Sprafkin, Ph.D.

The ADHD-SC4 is a 50-item rating scale completed by parents and teachers to screen for ADHD and Oppositional Defiant Disorder in children and teens from 3 to 18 years of age. Items are based on DSM-IV and worded for easy comprehension. The ADHD-SC4 contains a Peer Conflict Scale, which measures peer aggression, and a Stimulant Side Effects Checklist to monitor medication.

The Checklist as a whole shows a high correspondence with actual psychiatric diagnoses, and it differentiates clinical and nonclinical populations. The Peer Conflict Scale shows high agreement with direct observations of child aggression, and all four ADHD-SC4 categories are sensitive indicators of response to treatment.

Norms are based on teacher ratings of 1,527 children aged 3 to 12 and parent ratings of 522 children and teens from 3 to 18. Raw scores and T-scores are presented on Score Sheets according to symptom severity.

Requiring just 5 minutes, the ADHD-SC4 is a quick and reliable measure of attention problems.
