Notes

This is an amalgam of sequential branching questions asked during the initial Assessment Centre visit as part of the touchscreen questionnaire.

The question was dropped from the touchscreen protocol on 24/10/2016. It was reintroduced in early 2023, as it was required as a parameter for some repeat imaging measures.
