In psychiatric and other clinical settings, it can be helpful to assess the extent to which a patient is able and willing to follow a prescribed medication regimen. The Medication Adherence Scale provides a structured self-report approach to characterizing adherence-related behaviors and barriers.
The measure includes 25 items and typically takes about 5 minutes to complete. Items are intended to support clinical formulation by identifying factors that may facilitate or interfere with adherence, such as medication-related burden (e.g., scheduling and adverse effects), patient understanding and motivation, quality of clinician–patient communication, and the role of family or social support.
Results from the Medication Adherence Scale can be used to guide targeted interventions (e.g., additional psychoeducation, regimen simplification discussions, or involving supportive others when appropriate) and to monitor adherence over time. The instrument is attributed to NIPNI.
