The PDDBI-SV helps you quickly identify children at risk for autism spectrum disorder (ASD).

Features and benefits

  • Useful for a relatively broad range of ages (a younger range than that offered by most similar instruments).
  • Items assess nonvocal social problem behaviors typically reported in children with ASD as well as social behaviors that are present in typically developing children but that are absent, delayed, or occurring at a much lower rate in children with ASD.
  • Physicians using the PDDBI-SV may submit the cost of its administration for reimbursement by using CPT code 96110.246.

Test structure

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.

Technical information

  • Standardization sample included 369 parent ratings for children in the autism spectrum ranging in age from 1 year, 6 months to 12 years, 5 months. Children were diagnosed using the ADI-R and ADOS-G, widely considered the gold standards in autism diagnosis.
  • Internal consistency alpha was .87, in the upper end of the moderate range.
  • Sensitivity, specificity, positive predictive power, and negative predictive power of an ASD group and a non-ASD group were examined; the results support the instrument’s diagnostic validity.
