Values shown are the mean and standard deviations on each measure. The South Oaks Gambling Screen was administered only in the PG and PrG groups. Degrees of freedom differ due to missing data. WAIS VOC = WAIS vocabulary, WAIS BLOC REP = WAIS block design correct responses, WAIS BLOC TR = WAIS bloc design reaction time, ADHD = attention deficit hyperactivity disorder, BDI = Beck Depression Inventory, STAI-S = State version of the State-Trait Anxiety Inventory, STAI-T = Trait version of the State-Trait Anxiety Inventory, SOGS = South Oaks Gambling Screen.
