In total, 337 participants completed four self-report questionnaires: selected subscales of the World Health Organisation’s COVID-19 Behavioural Insights Tool, UCLA Loneliness Scale, State-Trait Anxiety Inventory–Trait Scale, Center for Epidemiologic Studies Depression Scale, and Beck Hopelessness Scale. In addition to descriptive statistics and intercorrelations, structural equation modelling was used to compare three models of the potential role (predictor or moderator/mediator) that the three abovementioned COVID-19-related variables could play in psychological wellbeing.enAnxietyBehaviourCovid-19DepressionLonelinessArticle
