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.
q3 i? In the late intervention period, there was no detectable effect of Level A or Level C on aggression as a main effect or by community. → Metropolitan Area Child Study Research Group 2002

q3 · i? · causal · r2
HLM analysis of the late intervention (Grades 5–6) high-risk sample. The article reports "no detectable effect of Level A or Level C on aggression either as a function of community or as a main effect"; no effect size is printed, so equivalence was not tested.
"there was no detectable effect of Level A or Level C on aggression either as a function of community or as a main effect."
Discussion¶
Related Claims¶
- Early-delivered Level A (classroom-only) and Level B (classroom plus small-group) interventions showed no significant effects on high-risk children's aggression — related
- For children receiving both early and late intervention, the Level C Community × Treatment interaction replicated: Aurora treated children decreased in aggression while Chicago treated children increased — reports the opposite
- Late-elementary (Grades 5–6) small-group peer-skills training (Level B) was associated with higher posttest aggression than control among high-risk children — related
- Early comprehensive (Level C) intervention effects on high-risk children's aggression interacted with community type, decreasing aggression in Aurora but increasing it in Chicago — related
- Clinical-significance analysis replicated the community interaction: Level C versus control differed significantly in Aurora and marginally in Chicago schools — related
