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 i2 In the late intervention period, Level B participants were more aggressive at posttest than controls, with a printed effect size of 0.62 SD. → Metropolitan Area Child Study Research Group 2002

Discussion¶
Related Claims¶
- Late-delivered Level A and Level C interventions showed no detectable effect 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 — 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
- 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
