Binge drinking on college campuses has been a hot topic in the popular media and in scholarly research. Flett, Goldstein, Wall, Hewitt, Wekerle, and Azzi (2008) report the results of a study relating perfectionism to binge drinking. In the study, students were classified into three groups based on the number of binge drinking episodes they experienced during the past month (0,1,2 or more). The students then completed a perfection-ism questionnaire including one scale measuring parental criticism. One sample item is 'I never felt that I could meet my parents' Standards.' Students rated their level of agreement with each item, and the total score was calculated for each student. The following results are similar to those obtained by the researchers.
