"to what extent items within a particular scale or instrument seem to be targeted at the same underlying construct or knowledge facet" (Taber, 2018, p.1294)
example of use:
"Not all papers reporting instruments include a listing of the final items included, but where authors do include the full list of items, it is possible for readers to consider for themselves the relationship between different items in a multi-scale instrument–to make a reader judgement of what might be called face equivalence, the extent to which items appear to be eliciting the same underlying knowledge facet, opinion or perception." (Taber, 2018, p.1288)
