两项研究调查了大学生对酒精和大麻相关问题以及危险消费和问题的评估（好坏）和预期可能性（可能-不可能）之间的联系。参与者提供了有关酒精使用、酒精相关问题以及对酒精问题的预期和评估的数据；大麻使用指数，大麻相关问题，大麻效应预期，大麻问题的可能性和评价。对酒精问题的评估与酗酒次数和酒精相关问题呈正相关。评估和预期之间的相互作用在预测酗酒次数方面是显著的。预期与酗酒和酒精相关问题呈曲线关系。与不吸食大麻的人相比，吸食大麻的人认为与大麻有关的问题不那么消极，也不太可能发生。对负面后果的预期（而非评估）与大麻使用强度显著相关。对问题的预期表明，大麻使用强度与大麻问题呈曲线关系。与女性相比，男性对酒精和大麻问题的评价不那么消极。总而言之，酒精-大麻问题的预期可能性以及对此类问题的评价是与使用有害酒精和大麻的责任增加有关的一个脆弱性因素。
Two studies examined the associations between evaluations (good-bad) and expected likelihood (likely-unlikely) of alcohol- and marijuana-related problems and hazardous consumption and problems among college students. Participants provided data on alcohol use, alcohol-related problems, and expectancies and evaluations of alcohol problems; marijuana use indices, marijuana-related problems, marijuana effect expectancies, and likelihood and evaluations of marijuana problems. Evaluations of alcohol problems were positively related to the number of binge drinking occasions and alcohol-related problems. The interaction between evaluations and expectancies was significant in predicting the number of binge drinking occasions. Expectancies demonstrated a curvilinear relationship with binge drinking and alcohol-related problems. Marijuana users evaluated marijuana-related problems as less negative and less likely to occur than did nonusers. Expectancies, but not evaluations, of negative consequences were significantly associated with marijuana use intensity. Expectancies of problems demonstrated, a curvilinear relationship with marijuana-use intensity and marijuana problems. Men evaluated alcohol and marijuana problems less negatively than did women. In summary, the expected likelihood of alcohol-marijuana problems and the evaluation of such problems represent a vulnerability factor associated with increased liability for hazardous alcohol and marijuana use.
