Morisky Medication Adherence Scale. The eight-item
Morisky Medication Adherence Scale (MMAS-8) is a self-report
scale that also is used commonly. It has been validated
for use in depression and physical conditions such as hypertension
and asthma.43 The strength of this questionnaire is
its informality. It puts the patient at ease by acknowledging
that many people face the same issues, thereby normalizing
the responses.
