Depression, Anxiety, and Stress Among Emerging Adult Undergraduates: A Longitudinal and Two-Cohort Study

Mental disorders constitute one of the population's principal health problems, especially among undergraduates. This quantitative study compared levels of depression, anxiety, and stress in a sample of emerging adult university undergraduates from a gender perspective (1) during the initial and intermediate years of emerging adulthood and (2) in two different cohorts. A total of 383 Spanish emerging adult university undergraduates were monitored longitudinally (2015-2018) and two cohorts were compared (2015-2020). Participants completed the validated Spanish version of the Depression Anxiety Stress Scale-21. Mean-level and rank-order stability was found across the two waves of the longitudinal study in relation to levels of depression, anxiety, and stress. Significant differences were found between the two cohorts, indicating higher levels of psychological distress in 2020 than in 2015. Women were found to have higher levels of psychological distress, particularly stress, than men in both waves and cohorts. Results are discussed in relation to the negative effects of the COVID-19 health crisis on the emotional health of emerging adults. The present study highlights the need to establish measures designed to improve the mental health of emerging adults, which was more severely affected by the COVID-19 crisis than by the aftermath of the 2008 financial crisis. It also underscores the need to develop interventions designed to alleviate the greater degree of stress suffered by women.
