The Morisky Medication Adherence Scale (MMAS) is a valid and reliable instrument that consists of 8 items that measure medication adherence. The scores of the MMAS-8 range from 0 to 8. This self-report scale consists of 7 items answered with a yes or no and 1 item with a 5-point Likert scale. A score below 6 indicates low adherence, a score between 6 to < 8 indicates medium adherence and a score of 8 indicates high adherence.
