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 early intervention period, there were no Condition × Community interactions or main effects of condition for Level A or Level B on aggression. → Metropolitan Area Child Study Research Group 2002

q3 · i? · causal · r2
HLM analyses of the early intervention high-risk sample for the classroom-only and classroom-plus-small-group conditions. The article reports "no Condition /H11003Community interactions or main effects for condition" for either intervention; no effect size is printed, so equivalence was not tested.
"there were also no Condition /H11003Community interactions or main effects for condition in the analyses of the effects of the Level A and Level B interventions."
Discussion¶
Related Claims¶
- Late-delivered Level A and Level C interventions showed no detectable effect on high-risk children's aggression — 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
- 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
- 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 — related
- Clinical-significance analysis replicated the community interaction: Level C versus control differed significantly in Aurora and marginally in Chicago schools — related
- In the early intervention sample, boys increased more in aggression than girls, but intervention effects did not differ by gender — related
