Trends in the prevalence and severity of depressive symptoms among undergraduate students at a South African University, 2016–2019

Abstract

University students are particularly vulnerable to mood disorders. This vulnerability may be increasing, with recent investigations reporting sharp rises in the prevalence of depression and other psychiatric disorders. Moreover, previous studies indicate that first-year undergraduates tend to show more depression and suicidal ideation than students in subsequent years. However, most studies in the extant literature emerge from high-income countries in the global north; relatively few focus on university students in low- and middle-income countries such as South Africa. Because students in low- and middle-income countries are more likely to be exposed to crime and trauma, and less likely to have easily accessible mental health services, they might be at even higher risk for developing mood disorders than their counterparts in high-income countries. Furthermore, most previous studies of mental health in university students analyse cross-sectional data and therefore cannot comment on longitudinal patterns in the data. To fill these knowledge gaps, the current study aimed to describe recent trends in depression and suicidal ideation among South African university students. We analysed both archival ( n = 2593) and original ( n = 499) Beck Depression Inventory-Second Edition reports, sampled between 2016 and 2019. As expected, depression and suicidal ideation scores increased significantly over time, and first-year students reported significantly more depression and suicidal ideation than students in subsequent years of study. These findings suggest that preventive interventions during sensitive periods of undergraduate study are imperative and provide a foundation for treatment strategies tailored to the needs of the most vulnerable South African students.
