Also, shown in Table 3, two-FCU engagers showed significant reductions in growth in child problem behavior from ages 2 to 5 (B = −.28, p < .05), and FCU assignment indirectly predicted lower levels of teacher-reported oppositional behavior at age 7.5 (indirect B = −.146, p < .05). The effect size of the intervention group compared with that of the control group was d = .55on growth from ages 2 to 5 and d = .29 for the indirect effect on teacher-reported oppositional problems at age 7.5.
