As expected, AD adolescents had substantially greater alcohol involvement than controls. For example, many more controls had never used alcohol or been intoxicated (χ2(1) = 12.38, p < 0.001; χ2(1) = 48.15, p < .001, respectively). Average lifetime alcohol usage was much higher in the AD group than in the control group (Welch’s F (1, 25.001) = 46.60, p < .001).
