Table 3. Normalization Analyses of Covariance Comparing Comparison Children's Baseline Discrepancy Scores to the Money Manipulation Discrepancy Scores for Children with ADHD.
Comparison | ADHD | Cohen's d | F | p | |||
---|---|---|---|---|---|---|---|
Mean | SD | Mean | SD | Effect Size | |||
Domain | |||||||
Academic | -0.26 | 0.71 | 0.09 | 0.85 | 0.45 | 12.46 | .000 |
Social | -0.11 | 0.86 | 0.46 | 0.90 | 0.65 | 27.39 | .000 |
Behavioral | -0.19 | 0.82 | 0.51 | 1.00 | 0.77 | 37.50 | .000 |
Note: Means are unadjusted for the effects of the covariate. Comparison n = 86; ADHD n ranged from 177-178. The effect of the covariate was significant (p < .05) for the behavioral domain only. Higher mean scores indicate greater overestimation of competence by the child relative to teacher report.
