Validity of the multidimensional assessment profile of disruptive behavior in autistic toddlers.

The MAP-DB-IT is a valid measurement tool for disruptive behavior in autistic toddlers. Clinicians should consider the use of the MAP-DB-IT for young autistic clients presenting with disruptive behavior to (a) discriminate between early developmentally appropriate tantrums from clinically salient dysregulation, and (b) refer to additional behavioral evaluations and services.
