(i) Morisky Medication Adherence Scale:
The Morisky Medication Adherence Scale (MMAS) is a validated assessment tool used to measure non-adherence in a several diseased populations such as CVDs, diabetes, arthritis, musculoskeletal conditions, and mental health. It was originally a four-item questionnaire survey with the dichotomous response categories ‘yes’ or ‘no’. The total score ranges from zero to four, which represents non-adherence and adherence, respectively 10. In 2008, a modified eight-item questionnaire was developed. The first seven items have a dichotomous response category with ‘yes’ or ‘no’, and the last item uses a five-point Likert response scale. The four items added on the modified version aim to identify and address the situational and emotional aspects of medication adherence of the patient11. The total score ranges from zero to eight with higher scores reflecting higher adherence and the score less than six denotes that the patient is non-adherent.
