Psychological impact of COVID-19 pandemic: Effects of optimism and uncertainty on distress during the lockdown in Spain

The objective of this study is to make a quick assessment of the psychological resources and emotional distress of the general population locked down during the COVID-19 pandemic (in Catalonia, Spain), and to observe their evolution over the course of two waves during lockdown: at two weeks and at one month (April 1th to 3th and April 17th to 19th). The longitudinal study collected data from 29,231 participants aged 18 or older through an online platform who answered questions which evaluated: optimism, uncertainty, perceived competence, self-efficacy, emotional distress, current job situation, sadness and anger in conjunction with sociodemographic variables. The main results indicated that general beliefs about the future, uncertainty, and optimism, together with beliefs about one's own conduct, such as perceived competence when facing the situation or self-efficacy to maintain routines, could predict the emotional distress experienced by an individual. A clear gender pattern was found. Between the two waves, optimism, perceived competence to manage the situation and self-efficacy to maintain routines decrease, uncertainty grows, and emotional distress remains. Taking these results into account we can prevent possible emotional scars and offer coping strategies to overcome the pandemic and the future situations of confinement in a more efficient way.
