Factor Structure of the Brief Comprehensive Effects of Alcohol Scale in Adolescents

Alcohol use among adolescents is a public health concern; therefore, it is important that studies that examine factors associated with adolescent drinking behaviors utilize measures that are well-validated for use with this population. The current study examined the factor structure and convergent validity of the Brief Comprehensive Effects of Alcohol scale, a measure of alcohol outcome expectancies and evaluations of expected outcomes, among adolescents (N = 1,074; 50% girls; Mage = 15.96 years, SD = 1.13, range = 13-18; 74% White) drawn from three independent studies (nsite 1 = 594; nsite 2 = 97; and nsite 3 = 383). Results yielded support for a four-factor structure for alcohol expectancies and two-factor structure for valuations. Moreover, the factor structure was partially or fully invariant across gender, age, and site. Thus, findings are similar, yet unique, to those identified in college samples. The convergent validity of the modified measure was supported, suggesting that the Brief Comprehensive Effects of Alcohol scale may be useful for assessing adolescents’ beliefs about alcohol
