Bozena Wielgoszewska

In response to the COVID-19 pandemic and subsequent national lockdown, the Centre for Longitudinal Studies and the MRC Unit for Lifelong Health and Ageing at UCL have carried out two online surveys. They surveyed the participants of five national longitudinal cohort studies which have collected insights into the lives of study participants.

Richard was a part of the team that have derived and made available non-response weights to enable users of the COVID-19 survey data to handle survey non-response by performing inverse probability weighted analyses.

In this talk, Richard will describe how these non-response weights were derived and demonstrate their ability to restore sample representativeness in the cohorts.

He will then discuss some alternative approaches for handling non-response (and missing data more generally), utilising multiple imputation, inverse probability weighting, and the combination of the two.
