The Tobacco, Alcohol and Drugs (grades 7–12) and Tobacco, Alcohol and Drugs-Revised (1 and 2 years post-high school) assessment instruments (Bureau of Labor Statistics 2002) were used to measure past year alcohol abuse. The instrument measured the number of days consuming 5+ drinks and number of days drunk in the past year. Because prevalence of alcohol abuse was low, a binary outcome was constructed where 1 = “any past year alcohol abuse” if participants responded any days of 5+ drinking or drunk, and 0 = “no past year abuse” if participants responded 0 days on both items. Technical reports and documentations are available from the Fast Track website (http://www.fasttrackproject.org/data-instruments.php). Over eight waves, 92.6% participants provided at least one wave of data and 84.6% provided at least three waves of data. Attrition analyses comparing the severity-of-risk screen score between those who provided at least one wave of data, and separately between those providing at least three waves of data, and those without any data found no significant differences for either intervention or control groups.
