From @MSEsperanza:
Apologies if that has already been posted—only able to skim but had a quick glance at some references in the paper and saw that at least in one participant-rated outcome measure, the item "minimal change" comprised all three: “a little better” and “a little worse" and "no change".
I wonder if this is thought to be a useful mixture and whether it's being used for other outcome measures in that trial or in other trials as well?
