Too many lemons to make lemonade? Disentangling mental health during the third wave of COVID-19 infections in Spain.

The study aimed to analyze the longitudinal change in mental health during the third wave of COVID-19 infections in Spain. Negative (e.g., emotional distress) and positive (e.g., positive functioning variables) outcomes were analyzed. Protective factors (e.g., resilience) as predictors of psychological adjustment (i.e., positive mental health, openness to the future, and low burden due to COVID-19) after ten months of the pandemic were also examined. The sample consisted of 164 participants, and self-reported questionnaires were administered at the beginning of the lockdown (March 2020), at the end of the lockdown (June 2020), and during the third wave (January 2021). Linear mixed models showed that individuals' emotional distress increased, and positive functioning variables (i.e., meaning in life, gratitude, resilience, and life satisfaction) decreased over time, but an increase was observed in some dimensions of posttraumatic growth. Regression analyses showed that resilience scores at all three data collection time points were significant predictors of positive mental health, openness to the future, and burden during the third wave. Mediation analyses showed that positive mental health and openness to the future were mediators of the effect of resilience on burden. The prolonged situation of the COVID-19 crisis had an important impact on positive and negative mental health. However, resilience may help to build up resources that can act as a buffer against adverse psychological effects.
