Longitudinal assessment of COVID-19 fear and psychological wellbeing in the United Kingdom.

The COVID-19 pandemic continues to impact global psychological wellbeing. To investigate the sustained impact of COVID-19 on wellbeing, the current study longitudinally assessed fear of COVID-19, anxiety, depression, intolerance of uncertainty, worry, sleep quality, loneliness and alcohol use during the pandemic in the United Kingdom. Timepoint 1 (T1; N  = 445) took place in February 2021 following the highest number of pandemic-related deaths in the UK. Timepoint 2 (T2, N  = 198) took place in June 2021 when pandemic-related deaths had declined considerably, and many had been vaccinated. At T1, COVID-19 fear predicted elevated levels of anxiety, depression, intolerance of uncertainty, worry, sleep quality and loneliness. At T2, we observed that levels of COVID-19 fear, depression, loneliness and sleep quality decreased. However, COVID-19 fear continued to predict elevated intolerance of uncertainty, worry and impaired sleep quality. These findings demonstrate the longitudinal impact of COVID-19 fear on psychological wellbeing.
