WHAT THE TEST MEASURES

About This Assessment

Morisky-Green Medication Adherence Scale Test - Symptoms and Signs

compliance

In routine clinical care, brief screening can help clarify how consistently a patient is taking prescribed medication. The Morisky-Green Medication Adherence Scale is a short self-report measure designed to identify potential nonadherence behaviors that may warrant follow-up discussion.

Developed by Green, L. and Morisky, D., it consists of 4 items and typically takes about 1 minutes to complete. Responses are commonly used to support clinical decision-making by flagging patients who may be missing doses or deviating from the prescribed regimen; results should be interpreted in context of the patient’s medical status, treatment complexity, and barriers to adherence. The Morisky-Green Medication Adherence Scale is intended as a screening tool and does not replace a comprehensive adherence assessment.
