Indispensability and comprehensiveness results of the 1 st Delphi round.

The proportion of panellists rating each of the 5 Likert scale points for ‘Indispensability (‘none’, ‘low’, ‘medium’, ‘high’, ‘very high’) of each individual EPA and ‘Comprehensiveness’ (‘strongly disagree’, ‘disagree’,’ neither disagree nor agree’, ‘agree’, ‘strongly agree’) of the set as a whole in round 1 are shown. The dotted red line shows the threshold value of 80%, all ratings to the left of this line should either be ‘high/agree’ (light green) or ‘very high/strongly agree’ (dark green) to indicate sufficient content validity.
