Phase two: Applying the Delphi technique
The Delphi technique was used to reach a convergence of opinion about the most important items to include in the questionnaire, based on the answers of an expert panel (23,24). This phase involved providing the AAMQ-V1 to the panel for review. The view format included a tabulation of all included items along with the wording of items that would accompany the items. The panel review was organized in two rounds. These rounds involved the panel members allocating scores on criteria related to each item. The experts were requested to assess the face, and the content validity (if the selected items covered the three domains of interest (Belief, Barrier, and Behavior)) of the AAMQ-V1.
