Note: All values are statistically significant at p<0.01. Pearson's product moment correlations for child self-report are presented above the diagonal. Pearson's product moment correlations for parent proxy-report are presented below diagonal. Pearson's product moment correlation effect sizes are designated as small (0.10), medium (0.30), and large (0.50).
