Revisiting the multidimensional interaction model of stress, anxiety and coping during the COVID-19 pandemic: a longitudinal study

Abstract

Background: Although the Multidimensional Interaction Model of Stress, Anxiety and Coping (MIMSAC) has been known for years, there is a lack of research examining this theory longitudinally in stressful events. This study aims to revisit the MIMSAC among university students during the COVID-19 pandemic. Methods: A prospective cohort study with the longitudinal design was performed during the first (W1, March 30–April 29, 2020) and second wave (W2, November 3–December 3, 2020) of the COVID-19 pandemic. A total of 216 university students with a mean age of 22 years (ranging from 20 to 36, M = 22.13, SD = 2.04) participated in the study. An online survey included Perceived Stress Scale, Coping Inventory for Stressful Situations, and Generalized Anxiety Disorder. Results: Due to the MIMSAC, all variables changed substantially across W1 and W2, adapting to an unpredictable environment. Women scored higher than men in stress, anxiety, emotion- and avoidance-oriented coping styles. We found the indirect effect of emotion-oriented coping on the stress-anxiety relationship and task-oriented coping on the anxiety-stress interaction. Avoidance was not found as a mediator in the stress-anxiety interaction. Conclusion: Emotion-oriented coping adversely affected mental health, increasing anxiety in response to stress during the COVID-19 pandemic. Task-oriented coping efficiently decreased stress in reaction to high anxiety, but only in men. Avoidance seems to be an ineffective coping style during the COVID-19 pandemic. Campus intervention programs should focus on reducing negative emotions and increasing the frequency of task-oriented coping strategies among university students.
