Notes: SBT = standard behavior therapy. MBT = modified behavior therapy. Med = medication main effect (0 = no medication, 1 = medication). ADHD = ADHD main effect. CP = conduct problem main effect. CU = CU main effect, Treatment = treatment main effect (SBT = 0, MBT = 1). Treatment*CU = Treatment by CU interaction.

^a= Summer Treatment Program point system (Pelham et al., 1998).

^b= IOWA Conners (Loney & Milich, 1982).

^c= Problem Rating Form (Waschbusch et al., 2013).

^d= Improvement Rating Scale (Pelham et al., 2000).

^e= Parent Treatment Satisfaction Ratings (Pelham et al., 2000).

Effect sizes are standardized mean differences computed as: (M_MBT - M_SBT) / Overall SD.
