OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Self-reported information on past utilization of health care is routinely used by many health researchers. However, the recall period of questions varies widely between surveys and this variation may affect the results of analyses. This seminar examines the role of length of recall period, mainly using a large experiment conducted in Sweden of self-reported hospitalizations of respondents. Respondents were asked a question on the number of nights they spent in hospital in which the recall period varied between one and twelve months. Our findings have conflicting implications for survey design as the preferred recall length depends on the objectives of the analysis. We will conclude by outlining planned experiments to build a better evidence base for designing surveys.
