Description
The PDDBI: Screening Version (PDDBI:SV) helps quickly identify children at risk for ASD. It produces one simple score, Social Deficit (SOCDEF), that measures the presence of inappropriate social behaviours. The PDDBI:SV is useful for a relatively broad range of ages (a younger range than that offered by most similar instruments).
Items assess non-vocal social problem behaviours typically reported in children with ASD as well as social behaviours that are present in typically developing children but that are absent, delayed, or occurring at a much lower rate in children with ASD.
Standardisation sample included 369 parent ratings for children in the autism spectrum.
Features and Benefits
Useful for a relatively broad range of ages (a younger range than that offered by most similar instruments).
Items assess non-vocal social problem behaviors typically reported in children with ASD as well as social behaviours that are present in typically developing children but that are absent, delayed, or occurring at a much lower rate in children with ASD.
Test structure
One simple score, Social Deficit (SOCDEF), measures both the presence of inappropriate social behaviours and the absence of appropriate social behaviours 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
Standardisation 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.
