< 0.001). Participants reported that the MEPA-III screener was acceptable (median score 8 out of a possible 10). The screener was feasible because the median completion time was 4.1 min (range 1.6-14.9). The online MEPA-III screener demonstrates good validity, acceptability and feasibility and can be used to characterize a Mediterranean-style diet pattern among participants with PD.
