Abstract

This longitudinal study explored the impact of COVID-19 on individuals in romantic relationships. The sample spans three waves: first confinement (n = 52), deconfinement (n = 49), and second confinement (n = 26). The study tested sociodemographic factors, psychological adjustment (anxiety, depression, stress, well-being), COVID-19 threat perception, dyadic coping, and relationship quality. Results from repeated measures ANOVA and fuzzy set qualitative comparative analysis (fsQCA) models revealed a decline in anxiety, depression, and stress symptoms, coupled with improved relationship quality over time. Well-being and dyadic coping remained stable, while COVID-19 threat perception increased. QCA models emphasized the predictive power of initial mental states (anxiety, depression, stress, and well-being at W1) on subsequent adjustment. Notably, shorter relationship duration, healthcare worker status, and not having children, when combined with prior mental states, explained increased symptoms and diminished well-being. The study underscores the significance of addressing these factors in individuals navigating romantic relationships during the pandemic.

Keywords: COVID‐19 threat perception; dyadic coping; fsQCA; longitudinal study; psychological adjustment; relationship quality.
