Generalized estimating equations (GEE) for repeated measures and effect size estimates for the intervention effect on outcomes in the posttest and 12-month follow-up (compared to the baseline) and by therapy modality.
| Outcomes | Sample | Post-Treatment | 12-Month Follow-Up | ||
|---|---|---|---|---|---|
| AOR (95% CI) | p Value | AOR (95% CI) | p Value | ||
| Peer problems | Group therapy (intragroup) | 1.10 (0.69, 1.74) | 0.67 | 0.50 (0.33, 0.75) | 0.001 |
| Individual therapy (intragroup) | 0.39 (0.24, 0.63) | ≤0.001 | 0.29 (0.19, 0.45) | ≤0.001 | |
| Total (intergroup) | 2.76 (1.64, 4.67) | ≤0.001 | 1.70 (1.10, 2.63) | 0.01 | |
| Prosocial behavior | Group therapy (intragroup) | 0.65 (0.42, 1) | 0.06 | 1.19 (0.72, 1.94) | 0.48 |
| Individual therapy (intragroup) | 1.84 (1.24, 2.73) | 0.002 | 2.51 (1,67, 3.79) | ≤0.001 | |
| Total (intergroup) | 0.27 (0.15, 0.48) | ≤0.001 | 0.42 (0.24, 0.72) | 0.002 | |
AOR = Adjusted Odds Ratio. CI = Confidence Interval. Higher scores denote greater symptomatology, except for Prosocial behavior (higher scores indicate more prosocial behaviors). Each analysis was adjusted for baseline assessment, children’s age and sex, and clustering within schools.
