BACKGROUND The lasting effects of the coronavirus disease 2019 pandemic are likely to be significant. AIMS This study tracked worry and rumination levels during the pandemic and investigated whether periods with higher COVID-related worry and rumination were associated with more negative mental health and loneliness. METHODS A quota survey design and a sampling frame that permitted recruitment of a national sample were employed. Findings for waves 1 (March 2020) to 6 (November 2020) are reported (N = 1943). RESULTS Covid-related worry and rumination levels were highest at the beginning of the first lockdown, then declined but increased when the UK returned to lockdown. Worry levels were higher than rumination levels throughout. High levels of COVID-related worry and rumination were associated with a five- and ten-fold increase in clinically meaningful rates of depression and anxiety (respectively) together with lower well-being and higher loneliness. The effects of COVID-related worry on depression and anxiety levels were most marked and clinically meaningful in individuals living with a pre-existing mental health condition. CONCLUSIONS Psychological interventions should include components that specifically target COVID-related worry and rumination. Individuals with pre-existing mental health conditions should be prioritised as we emerge from the current pandemic and in any future public health crises.
