The picture vocabulary test in UK Biobank is adapted from the NIH Toolbox Picture Vocabulary Test. The NIH test, for a US audience, was administered using a touchscreen by a member of staff, who also pronounced the words presented on the screen. Thus persons taking the test were presented with both an audio and visual depiction of the word. In contrast, the UK Biobank version of the test was delivered using a touchscreen only, so participants did not experience listening to the words. This document gives more detail about these differences and how the data was collected in the UK Biobank implementation.
