Seasonal affective disorder in college students: Prevalence and latitude

The Seasonal Pattern Assessment Questionnaire and the Beck Depression Inventory were used to evaluate a convenience sample of college students in northern New England for winter seasonal affective disorder (SAD) and subsyndromal SAD. Seventy-six students filled out the questionnaire and the inventory in mid-fall, then completed the inventory again in mid-February. The students who had moved from southern latitudes to northern New England were the most likely to experience increased depression in winter. Prevalence rates for SAD and sub-SAD combined (winter 13.2 and 19.7%, respectively) were slightly higher than those reported in previous research. The prevalence of SAD was also higher in female students, which was consistent with findings in previous research.
