Note. There was a 4-week interval for the test-retest correlations. Skewness values ranged from 0.19 to 1.67 (M = 0.80, SD = 0.34) and kurtosis values from −0.82 to 3.32 (M = 0.49, SD = .91) for the measures. RC = reliability coefficient (true score variance in the measure); ODD = oppositional defiant disorder.
