q3 · i1 · causal · r2

In the 20-school randomized prevention trial analyzed after three years (199 students), the Academic Achievement Composite showed a statistically significant positive effect with effect size 0.30 and p-value 0.02, while the Concentration Problems Composite effect size was -0.12 (p = 0.19).

"August et al. (2002) found, and the WWC confirmed, a positive and statistically significant difference between the intervention and comparison groups on the Academic Achievement Composite and no statistically significant difference between the intervention and comparison groups on the Concentration Problems Composite."

In the urban randomized effectiveness study (190 students analyzed after two years), the WWC confirmed no statistically significant difference on the Academic Achievement Composite; the effect size of 0.07 was not substantively important according to WWC criteria.

"August et al. (2003) found, and the WWC confirmed, no statistically significant difference between the intervention and comparison group on the Academic Achievement Composite."
