LR is the level of response to alcohol measured by the Self Report of the Effects of Alcohol questionnaire; PEER drinking is measured by the maximum peer score for each of the three Important People and Activities questionnaire items where peer frequency scale = 0 “none” to 7 “daily”, peer max drinks scale = 0 “none” to 4 “10+”, and drink status from 1 (abstinent) to 5 (heavy drinking) with 3 = light drinking; EXPECTANCY is measured by the scores on the Alcohol Expectancies Scale and z-scored within adult and adolescent versions; COPE is the score on the Drinking to Cope scale (note for COPE in the figures the 6 cope items placed into 3 parcels of 2 items each).
