RT Journal Article T1 A new perspective from time use research on the effects of social restrictions on COVID-19 behavioral infection risk A1 Gershuny, Jonathan A1 Sullivan, Oriel A1 Sevilla, Almudena A1 Vega Rapun, Margarita A1 Foliano, Francesca A1 Lamote de Grignona, Juana A1 Harms, Teresa A1 Walthery, Pierre K1 Social restrictions K1 COVID-19 K1 Infection risk AB We present findings from three waves of a population-representative, UK time-use diary survey conducted both pre- and in real time during full ‘lockdown’, and again following the easing of social restrictions. We used an innovative online diary instrument that has proved both reliable and quick-to-field. Combining diary information on activity, location, and co-presence to estimate infection risks associated with daily behavior, we show clear changes in risk-associated behavior between the pre, full-lockdown and post full-lockdown periods. We document a shift from more to less risky daily behavior patterns (combinations of activity/location/co-presence categories) between the pre-pandemic pattern and full lockdown in May/June 2020, followed by a reversion (although not a complete reversal) of those patterns in August 2020 following the end of the first lockdown. Because, in general, a populations’ time use changes relatively slowly, the behavioral changes revealed may be interpreted as a consequence of the UK COVID-19 lockdown social restrictions and their subsequent relaxation.
