Making it “EASI” for pediatricians to determine when toddler tantrums are “more than the terrible twos”: Proof-of-concept for primary care screening with the Multidimensional Assessment Profiles–Early Assessment Screener for Irritability (MAPS-EASI).

Up to 20% of youth have impairing mental health problems as early as age 3. Early identification and intervention of mental health risks in pediatric primary care could mitigate this crisis via prevention prior to disease onset. The purpose of this study was to establish the feasibility and acceptability of implementing a brief transdiagnostic screening instrument in pediatric primary care for irritability and corollary impairment.
