Medication Adherence Report Scale (MARS)™
The MARS™ measures self reported adherence to medicines, it assesses both intentional and unintentional non-adherence.
Where can it be used?
The MARS™ was originally validated within asthma in which studies supported both it’s reliability and validity. There have been subsequent studies in chronic illness samples including:
- Heart failure
- Myocardial infarction
- Rheumatoid arthritis
It provides a ‘spot check’ estimate of a patient’s adherence behaviour, it can also be used within exploratory studies to identify a cohort of patients with low adherence. Another use for the MARS™ is to evaluate the impact of interventions. It is available in a variety of languages.
How does it work?
The MARS™ measures adherence in a non-threatening manner to minimize social pressure which leads to under reporting of non-adherence. Respondents indicate their agreement with statements about their medicine use on a 5 point Likert scale. The MARS™ is available in 4, 5 or 10 item versions.
