PDD Behavior Inventory™ Screening Version

The PDDBI-SV helps you quickly identify children at risk for autism spectrum disorder (ASD).One simple score, Social Deficit (SOCDEF), measures both the presence of inappropriate social behaviors and the absence of appropriate social behaviors and is classified into one of six levels of severity, ranging from extreme symptoms to ASD/social deficits unlikely, letting you know quickly whether the child is at risk.
