ABSTRACT
BACKGROUND: The objective was to analyze the factors that influence reactions to confinement situations, such as personality, humor, coping with stressors, and resilience, and to compare this population with a normal situation of exposure to an intense academic stressor such as a partial test, and with the confinement situation caused by the COVID-19 pandemic. METHODS: A longitudinal study was performed involving 116 health sciences students from Spain. Three situations were evaluated: a basal situation of normality at the beginning of the course, situation facing an academic stressor (partial test), and confinement situation due to COVID-19. The Positive and Negative Affect Schedule (PANAS), Coping Orientation to Problems Experienced (COPE), Connor-Davidson Resilience Scale, and NEO-FFI scale were used. RESULTS: Significant differences were observed in the increase in negative humor and decrease in positive one, as well as decrease in "Focus on and Venting of Emotions". Personality factors that better predict humor at confinement were "conscientiousness" for having positive humor and low "extraversion" for negative humor. CONCLUSIONS: The confinement situation due to COVID-19 has caused changes in predominant humor, as well as in coping strategies. Personality factors positively or negatively influence the situation.
