The Morisky Medication Adherence Scale

Morisky Medication Adherence Scale

The Morisky Medication Adherence Scale (MMAS) is a medication adherence questionnaire used to assess medication adherence. The MMAS-8 has 8 questions, while the MMAS-4 has four questions designed to address predictors of medication adherence. The MMAS-4 was developed in 1986, and the MMAS-8 was developed and validated more recently as a more accurate tool.

The questions on the MMAS-8 are:

1.     Do you sometimes forget to take your medicine? Yes/No

2.     People sometimes miss taking their medicines for reasons other than forgetting. Thinking over the past 2 weeks, were there any days when you did not take your medicine? Yes/No

3.     Have you ever cut back or stopped taking your medicine without telling your doctor because you felt worse when you took it? Yes/No

4.     When you travel or leave home, do you sometimes forget to bring along your medicine? Yes/No

5.     Did you take all your medicines yesterday? Yes/No

6.     When you feel like your symptoms are under control, do you sometimes stop taking your medicine? Yes/No

7.     Taking medicine every day is a real inconvenience for some people. Do you ever feel hassled about sticking to your treatment plan? Yes/No

8.     How often do you have difficulty remembering to take all your medicine?

__ A. Never/rarely

__ B. Once in a while

__ C. Sometimes

__ D. Usually

__ E. All the time


Morisky Medication Adherence Scale Scoring

The scoring for the MMAS-8 is simple. Each “yes” response for each of the first 7 questions is worth 1 point, and a “no” is worth 0 points. For the final question, a response of “A” is worth 0 points, and a response of “B,” “C,” “D,” or “E” is worth 1 point. Add up the points.

·      Total of more than 2 points: low adherence.

·      Total of 1 or 2 points: medium adherence.

·      Total of 0 points: high adherence.
