Association between history of academic failure during dental school and self-reported depression, anxiety, and stress: A retrospective cohort.

Abstract

To investigate the association between history of academic failure (HAF) and self-reported depression, anxiety, and stress among undergraduate dental students. This study involved 244 dental students from one university. An online questionnaire collected information on the following variables: socioeconomic status, behavior, use of licit/illicit drugs, and the choice of dentistry as an undergraduate field of study. The 21-item Depression Anxiety Stress Scale (DASS-21) was applied. HAF in at least one subject during a participant's undergraduate tenure was defined as the main outcome. Bivariate and multivariate analyses were performed using Poisson regression with robust variance. In addition, a subgroup analysis was performed for the variable "dentistry as the first choice for undergraduate studies." The prevalence of HAF was 25.00% (n=61). Among those students, the mean number of academic failures was 5.41±6.38 (range: 1-33). Higher rates of HAF were observed among older and non-white dental students. Moreover, those who self-reported at least severe depression presented a 79% higher HAF prevalence ratio (PR) (95% confidence interval [95% CI]: 1.15-2.80). Similar findings were detected among those who reported (PR: 1.79; 95% CI: 1.06-4.46) or did not report (PR: 2.21; 95% CI: 1.10-4.46) interest in dentistry as a first undergraduate option. Conversely, among women and students who did not choose dentistry as their first option, HAF was significantly lower (PR: 0.41; 95% CI: 0.21-0.80). Higher HAF rates are observed in students who are older, non-white, and self-report at least severe depression. However, dentistry as a first option for undergraduate studies was not associated with HAF.
