Subclaims¶

q3 i3 Teacher-reported symptom reductions had Hedges' g effect sizes from -1.02 to -1.14 and functioning improvements from 0.80 to 1.40, significant after Benjamini-Hochberg correction. → Feil 2016

Feil 2016¶

Feil, E. G., Small, J. W., Seeley, J. R., Walker, H. M., Golly, A., Frey, A., & Forness, S. R. (2016). Early intervention for preschoolers at risk for attention-deficit/hyperactivity disorder: Preschool First Step to Success. Behavioral Disorders, 41(2), 95-106. https://eric.ed.gov/?id=ED581149

q3 · i3 · causal · r2

Covariate-adjusted regression models (Mplus 6.0, full information maximum likelihood, baseline covariate) on the 45-child ADHD-risk subsample of the PFS randomized controlled trial, with Benjamini-Hochberg correction. The article reports Hedges' g effect sizes "ranged from −1.02 to −1.14" for symptoms and "from 0.80 to 1.40" for functioning, all significant at p ≤ .001 in Table 3.

"Hedges' g effect sizes ranged from −1.02 to −1.14. For teacher-reported improvements in functioning, effect sizes ranged from 0.80 to 1.40."
