Prediction of psychopathology during the COVID-19 pandemic using linear and non-linear methodologies: Importance of COVID-19 threat perception, emotional competencies and resilience

The presence of a mental or physical illness prior to the pandemic, the perceived threat from COVID-19, resilience or emotional intelligence may influence the onset or increase of psychopathology during the COVID-19 lockdown. The aim was to assess predictors of psychopathology by comparing two statistical methodologies (one linear and one non-linear). Method. - A total of 802 Spanish participants (65.50% female) completed the questionnaires independently after signing informed consent. Psychopathology, perceived threat, resilience and emotional intelligence were assessed. Descriptive statistics, hierarchical regression models (HRM) and fuzzy set qualitative comparative analysis (fsQCA) were conducted. Results. - The data obtained through the HRM showed that the presence of a previous mental illness, low resilience and emotional clarity, high emotional attention and repair, and COVID-19 threat perception predicted 51% of the variance in psychopathology. Results obtained from QCA showed that different combinations of these variables explained 37% of high levels of psychopathology and 86% of low levels of psychopathology, highlighting how the presence of prior mental illness, high emotional clarity, high resilience, low emotional attention and low perceived COVID-19 threat play a key role in explaining psychopathology. Conclusions. - These aspects will help promote personal resources to buffer psychopathology in lockdown situations. (c) 2023 L'Auteur(s). Publie par Elsevier Masson SAS.
