Table 1 describes the characteristics of the 1028 COGA Youth Panel participants across Time 1 (Baseline), Time 2 (2 years after baseline), and Time 3 (2 years after Time 2). At Baseline these drinking but non-alcohol dependent subjects were on average 18 years old, their mean SRE5-LR score was 3.5, and their mean adolescent and adult Barratt Impulsivity scores were 73 and 64, respectively. At Time 2, participants reported peers who were perceived to be between light and moderate drinkers and consumed alcohol about 1.2 days per week, with a maximum quantity of 4.1 standard drinks (10–12 g ethanol) per occasion.
