The present study examines the role of personality traits, interpersonal relationships, and sociodemographic factors on perceived stress, related to COVID-19, and compliance with measures to mitigate its spread. Data were collected in the midst of the 'first wave' lockdown, with the survey completed in full by 963 participants. We measured stress, directly related to the pandemic, rather than general stress, and were able to distinguish between symptoms of emotional, behavioural, cognitive, physical stress, and alienation with high concordance. We included personality scoring with standardized T-scores, allowing for cross-study comparison, and a broader questionnaire on the participants' support for COVID-19 mitigation measures. Results of the multiple regression models indicated that low emotional stability and introversion, and high conscientiousness, common conflicts with loved ones, and some demographics (female gender, middle age, chronic health problems) correspond to elevated stress. Conscientiousness was positively associated with total stress and some of its components, whereas opposite results were found for emotional stability. Extraversion was negatively correlated to total stress, its emotional and physical components, and alienation. Surprisingly, increased stress was not related to greater measure adherence. The present results shed light on how personality, interpersonal relationships, and sociodemographic factors influence people's stress response during a pandemic.
