The roles of stress mindset and personality in the impact of life stress on emotional well-being in the context of Covid-19 confinement: A diary study.

Abstract

Previous studies indicate that COVID-19 confinement has led to an increase in psychological distress and a decrease in overall well-being. This longitudinal study aims to investigate how stress mindset and personality traits moderate the impact of life stress on the development of emotional well-being during the COVID-19 pandemic confinement. Our study collected daily life stress and emotions data from 134 participants over 14 consecutive days using the diary method. We used hierarchical linear modeling (HLM) to analyze the data, examining within-person and between-person effects. Life stress predicted moderate increases in positive emotions and strong increases in negative emotions over time. A stress-is-enhancing stress mindset was associated with greater positive emotions at baseline and mitigated the link between life stress and negative emotions. Among the Big Five personality traits, extraversion, openness, agreeableness, and conscientiousness were associated with higher baseline levels of positive emotions. Agreeableness and conscientiousness mitigated the link between life stress and negative emotions. Neuroticism was associated with higher baseline levels of negative emotions and moderately mitigated the link between life stress and positive emotions. The interaction between neuroticism and stress-is-enhancing mindset predicted greater negative emotions and mitigated the link between life stress and positive emotions. In contrast, the interaction between stress-is-enhancing mindset and the other four personality traits mitigated the positive link between life stress and negative emotions. Overall, these findings suggest that life stress from confinement leads to a decrease in daily emotional well-being as the confinement prolongs. Personality traits-agreeableness, conscientiousness, and a stress-is-enhancing stress mindset-act as protective roles in mitigating life stress' effect on reduced emotional well-being over time. The findings advance our knowledge in understanding the roles of personality traits and stress-is-enhancing mindset in explaining the heterogeneity in the impact of life stress on emotional well-being.
