Note. All rs above .04 in absolute value are significant at p < .001. Sample size for individual correlations ranged from 5,109 to 5,423 due to missing data from specific sources (e.g., teacher ratings and student reports). BASC = Behavioral Assessment Scale for Children; PBFS = Problem Behavior Frequency Scale; RFI = risk factor index.
