Studies of adolescent alcohol use typically sample intact high school populations. This study assessed "street" adolescents alienated from the mainstream educational system. Despite recent optimism regarding adolescent substance use, these respondents showed considerable alcohol consumption, drinking to get drunk, and problems. The major correlates of substance abuse were "personal" drinking motives, expectancies of alcohol effects and peer behavior. Thus, adolescents who would not appear in typical studies showed much stronger alcohol involvement than the general population, with individual differences best accounted for by attitude variables relevant to a "stress-vulnerability" approach to substance abuse.
