The first round
The expert panel consisted of six categories (doctors, pharmacists, pulmonologists, academics, people with asthma, and last-year pharmacy students). Each item included in the AAMQ-V1 was evaluated by the expert panel in terms of readability, clarity of words, consistency of the style layout, relevance, and importance (22). The experts were requested to rank the importance of each item included in the AMMQ-V1 using a 5-point Likert scale (strongly agree this item is important, agree this item is important, neutral, agree this item is not important, and strongly agree this item is not important). The mean score for the importance of each item was calculated. Items agreed upon as being important questions by a percentage of 70% or more of the panel (mean item importance score ≥4, i.e. strongly agree this item is important or agree this item is important) were included in the final version of the questionnaire. Items with no clear consensus such as those that had an agreement score between 50% and 70% produce the second version of the questionnaire (AAMQ-V2) and were retained in the second round (21,25,26). The expert panel was also asked about the appropriate acceptable number of items that should be included in the adherence assessment questionnaire. In round one, adding, deleting, editing, and rephrasing of the items were undertaken based on panel review (26).
