5 minutes to fill out, and can be used with all drinkers, including those in their early to mid teens, the usual times of experiencing the first drinking effects (Faden and Fay, 2004). The SRE was constructed to ask questions that parallel four of the items used to report changes in subjective feelings of intoxication during alcohol challenges on the SHAS. The questionnaire has a Cronbach alpha >0.90, and a one-year retest reliability between 0.72 and 0.82, and a five-year retest kappa of .66 (Schuckit et al., 1997b, 2004). The external validity of this measure includes lower LR scores (or a greater number of drinks required for effects on the SRE) for subjects at high alcoholism risk including children of alcoholics, Koreans, and American Indians (Ehlers et al., 1999; Schuckit et al., 1997b; Wall et al., 1999). Lower LR values, as measured by a higher number of drinks for effects on the SRE, correlated as high as 0.5 with the maximum drinks ever consumed in 24 hours in 12-to-14 year olds, and ∼0.25 at this early age with the number of relatively minor alcohol-related problems ever experienced (Schuckit et al. 2005b, 2006).
