Item 1 had three possible responses: better, same or worse. We considered that the answer reflecting a potential difficulty was “worse” while the other two reflected no difficulty. Therefore, were coded as follows: 1 (worse) and 0 (same/better).

Items 3 and 7 have also three possible answers: good, very good or bad. The first two answers do not reflect difficulties and were coded 0 while the answer “bad” was coded 1 as it reflected a perceived difficulty.
