q2 · i? · causal · r1

Retrospective subsample selection using parent report on the Early Childhood Inventory-4, a DSM-IV-based screening tool rated on a four-point frequency scale. Seventeen children had been randomized to the experimental condition and 17 to the usual-care control condition.

"A cutoff of two or more stan- dard deviations above the mean identified a subsample of 34 of the 126 children (27%) from the larger efficacy trial who met criteria for being at risk for developing ASD."

Discussion¶

Related Claims¶

• The ASD-risk subsample differed from the non-identified sample on all parent-reported baseline outcomes but on only one teacher-reported measure (SSiS Empathy) — related
• FSN showed similar effects for students with or at risk of comorbid ADHD, ASD, or anxiety disorders — related
• More than a third of preschoolers screened for externalizing behavior in the PFS trial also met criteria as at risk for comorbid ADHD, and differed from nonidentified peers at baseline — related
