Get to know the tests in UK Biobank

Data collection now includes tests of memory, reasoning, executive function, and vocabulary - when the current data collection wave is complete researchers will be able to request access to work with these data for approximately 90,000 participants. There are currently data available for 20,000 participants and UK Biobank release new data every few months.

A DPUK report describing the tests and the rationale for their development will be available on this page in summer 2019. Please see this UK Biobank webpage if you require more information now.

How do UK Biobank tests compare with standard tests?

UK Biobank has developed its own cognitive assessments which differ from commonly used tests in other studies. DPUK carried out a test-retest reliability and concurrent validity study, comparing UK Biobank tests with these well-used tests. This work will help researchers who are interested in running cross-cohort analyses using UK Biobank cognitive data. 

A report detailing this work provides psychometric information for researchers using the UK Biobank resource, and will be available on this page in summer 2019.
