Challenges to self-isolation among contacts of cases of COVID-19: a national telephone survey in Wales

Abstract

BACKGROUND: Self-isolation is challenging and adherence is dependent on a range of psychological, social and economic factors. We aimed to identify the challenges experienced by contacts of coronavirus disease 2019 (COVID-19) cases to better target support and minimize the harms of self-isolation. METHODS: The Contact Adherence Behavioural Insights Study (CABINS) was a 15-minute telephone survey conducted with confirmed contacts of COVID-19 (N = 2027), identified through the NHS Wales Test Trace Protect (TTP) database. RESULTS: Younger people (aged 18-29 years) were three times more likely to report mental health concerns (adjusted odds ratio [aOR]: 3.16, 95% confidence interval [CI]: 2.05-4.86) and two times more likely to report loneliness (aOR: 1.96, CI: 1.37-2.81) compared to people aged over 60 years. Women were 1.5 times more likely to experience mental health concerns (aOR: 1.51, 95% CI: 1.20-1.92) compared to men. People with high levels of income precarity were eight times more likely to report financial challenges (aOR: 7.73, CI: 5.10-11.74) and three times more likely to report mental health concerns than their more financially secure counterparts (aOR: 3.08, CI: 2.22-4.28). CONCLUSION: Self-isolation is particularly challenging for younger people, women and those with precarious incomes. Providing enhanced support is required to minimize the harms of self-isolation.
