The results of these two studies demonstrate strong psychometric support for the B-BAES. Item analyses and confirmatory factor analysis in an independent sample of heavy social drinkers supported the six items that comprise the B-BAES. The subscale scores, B-STIM and B-SED, demonstrated very strong to excellent internal consistency reliability, and correlated highly with corresponding scores of the BAES. Further, in an intensive prospective design, the B-BAES subscale scores were comparable to the full BAES subscale scores in predicting future binge drinking, which establishes the predictive validity of this abbreviated measure. These results support the use of the B-BAES in a variety of research designs, including repeated measurement in the human laboratory, ecological momentary assessment or mobile phone applications to measure brief in vivo alcohol responses, or functional brain imaging procedures which require brief assessments on keypads and minimal participant movement. In these types of paradigms, and others, the B-BAES could be used efficiently and reliably to assess subjective effects of alcohol to test models of risk related to stimulant and sedative effects. In addition, because of the increased ease of
