Post-COVID-19 Consequences and Psychological Well-Being in Students: The Mediating Role of Trait Anxiety

The long-term psychological consequences of COVID-19 remain insufficiently understood in student populations. This study examined the association between post-COVID-19 consequences and psychological functioning in university students, focusing on the mediating role of trait anxiety. A total of 7482 students aged 17 to 23 years completed an online survey assessing COVID-19 history, post-COVID-19 consequences, psychological well-being (WHO-5), subjective happiness (SHS), life satisfaction (SWLS), and trait anxiety (STAI). Participants were classified into three groups: no history of COVID-19, COVID-19 without post-COVID-19 consequences, and COVID-19 with post-COVID-19 consequences. Group differences were analyzed using ANOVA with Tukey post hoc tests, followed by regression and mediation analyses controlling for age and sex. Students reporting post-COVID-19 consequences showed higher trait anxiety and lower psychological well-being, subjective happiness, and life satisfaction than both comparison groups. Regression analyses indicated that poorer psychological functioning was associated specifically with post-COVID-19 consequences rather than COVID-19 history per se. Mediation analyses among previously infected students showed that trait anxiety statistically mediated these associations, accounting for 61% of the effect on psychological well-being, 84% on subjective happiness, and 68% on life satisfaction. These findings highlight trait anxiety as an important psychological factor statistically accounting for the association between post-COVID-19 consequences and reduced well-being.
