For a study of elevated psychological distress, the authors used data based on a national probability sample of 7,800 Canadian undergraduate students from 16 universities. They used the 12-item General Health Questionnaire to assess mental health. Thirty percent of the students in the sample reported elevated psychological distress, which varied significantly according to sex, region, year of study, and recreational and academic orientation. Rates of elevated distress were significantly higher among the students than among the general population in Canada.
