Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q4 i2 In an RCT, the PTR-YC group showed a significantly greater pre-to-post increase in SSIS social skills scores than the BAU group, with a small interaction effect. → Glen Dunlap 2018

q4 · i2 · causal · r2

Mixed ANOVA in the same classroom-level RCT on the SSIS social skills subscale found a significant time-by-group interaction, "F(1, 158) = 10.52, p = .001", ηp² = .062; posttest means were 66.11 (PTR-YC) vs 55.37 (BAU), with similar pretest levels.

"Results for the mixed ANOVA specific to SSIS social skills revealed a statistically interaction effect between time and group, F(1, 158) = 10.52, p = .001. The effect size was small for the interaction analyses (ηp 2 = .062)."
