Corrigendum to ‘Tiered restrictions for COVID-19 in England: Knowledge, motivation and self-reported behaviour’ [Public Health 204 (2022) 33–39, (Public Health (2022) 204(33-39) (S0033350621004789), (10.1016/j.puhe.2021.12.016))

The authors regret that there are some errors with this manuscript.¹ There is an issue with labelling for socio-economic grade. The item for this variable asks participants to state the profession of the highest earner in the household. We categorised participants into two groups: highest earner works in a manual occupation, and highest earner does not work in a manual occupation. The levels of these variables are referred to in some of our project's manuscripts as “socio-economic grade C1DE” and “socio-economic grade ABC1” respectively (see Table 1). These would be better denoted as “highest earner in household works in a manual occupation” and “highest earner in household does not work in a manual occupation”. This labelling error came about through multiple iterations of documents. [Table presented] For this study, 482 participants (27.9%) reported that the highest earner in their household worked in a manual occupation (highest earner did not work in a manual occupation: n = 1204, 69.7%; missing data [reported “other” and so could not be categorised]: n = 42, 2.4%). When using socio-economic grade, 764 participants (44.2%) were categorised as belonging to the C2DE group (ABC1: n = 922, 53.4%; missing data: n = 42, 2.4%). A sensitivity analysis adjusting for socio-economic grade rather than the highest earner being a manual worker indicated that there were no meaningful differences in other analyses investigating the test, trace, and isolate system, and no difference to the conclusions drawn.² The authors would like to apologise for any inconvenience caused.
