Phase two: Applying the Delphi technique
Forty-eight participants were chosen as the expert panel (eight from each category). The mean age of expert panel was 35 years (SD= 10.70), and 62.5%of them were females.
The entire expert panel (100%) agreed that the items were understandable, and that the questionnaire had a good layout and style. Most of the expert panel (85.42%) agreed that the items were written clearly. The expert panel was asked about the appropriate acceptable number of items in an adherence assessment questionnaire, their answers varied widely and ranged from 6 to 25 items, within an average answer of 15 items.
After conducting the first round in the Delphi technique, twelve items were agreed upon by a percentage of 70% or more, as being important items to assess adherence. Eight items were excluded because they had an agreement score of less than 50%. Eleven items scored between 50% and 70% and they were reassessed in the second round. Table II highlights the agreement score on the importance of each item after the first round.
After conducting the second round, with 11 items, only one question scored above 70%. To conclude, the final AAMQ consisted of 13 items.
