| ADHD Symptoms (DBD-RS) | |||
| Inattention-Parent | 8.1 (1.2) | 0.09 (0.4) | <.001 |

Except where noted, values represent the mean (SD). SR composite = mean of standardized parent-reported SR and child-reported BAS; Cognition = mean of standardized SSRT on the SST, percent accuracy on the 1-and 2-back, and CPT hits; DBD-RS = Disruptive Behavior Disorder Rating Scale, values represent the total number of symptoms endorsed on the DBD-RS (i.e., rated as ‘pretty much’ or ‘very much’).
