Subclaims¶

q3 i3 Subsample analyses (n = 42 ADHD elementary; n = 34 ASD, n = 45 ADHD, n = 38 comorbid anxiety preschool) produced effect sizes of similar magnitude to full samples, many in the large range (e.g., 1.16 on teacher-reported SSBD-ABI). → Andy J. Frey 2023

q3 · i3 · review · r2

Preschool ADHD subsample analysis (Feil et al., 2016; n = 45 of 126) from the Feil et al. (2014) RCT. The review reports a large ES of 1.16 on teacher-reported SSBD-ABI and SSiS-SS and a medium ES of 0.65 on parent-reported SSiS-SS, of similar magnitude to full-sample effects.

"ESs across prosocial and PB domains ranged from 0.65 (medium; improvement index = +24.2) on the parent-reported SSiS-SS to 1.16 (large; improvement index = +37.7) on both the teacher-reported SSBD-ABI and the teacher-reported SSiS-SS."

Related Claims¶

• 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
• In the FSN national effectiveness trial (Sumi et al., 2013), effect sizes were smaller, ranging from 0.21 to 0.67 — related
• First Step Next replication RCTs produced small to large effect sizes and statistically significant behavioral gains compared with control conditions — a broader claim this one bears on
• Preschool First Step to Success produces statistically significant postintervention improvements on all teacher-reported symptom and functioning outcomes for preschoolers at risk for ADHD, with large effect sizes — related
• Parent-reported outcomes for the PFS ADHD-risk subsample improved in the medium range for both home-setting symptoms and social functioning — related
• In the PFS ADHD-risk subsample, 54% of intervention children versus 11% of controls responded or improved by teacher-rated clinical criteria — related
