A study on optimism as a psychological strength in nurses through a prospective study from the outbreak of the COVID-19 pandemic to two years later.

Aims and objectives: This study analyzes, in nurses, the influence of openness to experience and hardiness (assessed at baseline and one year after the COVID-19 pandemic respectively) on the development of optimism (assessed two years after the COVID-19 pandemic). Concerns about self-contagion were included as a moderating variable, given their relevance as a risk factor. Background: Nurses have been among the healthcare professionals most affected by the COVID-19 pandemic. Most previous studies have focused on the variables contributing to psychological symptoms, whilst the attention given to the variables adding to the well-being of these professionals has been much scarcer. Design: A prospective study was carried out. Methods: This study was carried out using three data collection periods: Period 1 (From May to June 2020), Period 2 (From January 2021 to April 2021), and Period 3 (From April 2022 to July 2022), with the participation of 151 Spanish nurses, using online self-reporting questionnaires. The study followed the STROBE statement. Results: The results showed that the proposed model was statistically significant. There was a positive effect of openness to experience (year 2020) on hardiness assessed one year later (year 2021). Similarly, hardiness had a positive effect on optimism assessed another year on (year 2022). Conclusions: Concerns about self-contagion behaved as a moderator in the relationship between openness to experience and hardiness (the relationship between openness and hardiness was statistically significant when contagion concern was higher). Relevance to clinical practice: In-depth understanding of the psychological processes that trigger psychological strengths (i.e. optimism) as a result of adverse situations (i.e. COVID-19 pandemic) is essential in promoting the mental health of healthcare professionals. Interventions targeting resilient personality traits and cognitive flexibility are key to this goal. No Patient or Public Contribution: The participants contributed exclusively to the collection of the sample.
