Notes
This is the estimate of the participant's vocabulary level, at the end of the test according to the original scoring criteria. It ranges between -11 (most basic) and 11 (most complex) .
Field 6365 gives the Standard Error associated with this estimated value.
Note: the original scoring criteria was obtained from a presentation of the words in both audio and visual forms, to persons in the USA. As such the difficulty levels of the words are not directly comparable to the UK Biobank implementation in which words were presented in visual form only to persons in the UK.
It is strongly recomended that Field 26302 should be used in preference to this measure.
