This paper reports the design and outcomes of a pilot study
for the UK Household Longitudinal Study (UKHLS), Understanding Society, to
develop and test the feasibility of collection of biomarkers by trained non-clinical
interviewers. Feasibility tests performance of procedures, that they are
technically satisfactory and reasonable in relation to alternatives. The
dimensions reported are recruitment and training of interviewers, completeness,
acceptability and time required for data collection, and quality of the
biological samples. Some comparisons are made with measures conducted by nurses
in wave 2 of the UK Household Longitudinal Study, Understanding Society.
Biomeasures included anthropometrics, blood pressure, grip strength and the
collection of saliva and dried blood spots. We implemented measurement
protocols, introduced training and certification of interviewers, who then
collected data from 92 participants. The study produced information about
duration of collection, participation and quality of blood and saliva samples.
The pilot study informs the design decisions about the biosocial component of
Understanding Society.
