The Altarum Consumer Engagement (ACE) Measure™ is a 21-item measure that provides a valid alternative to other patient engagement measures.
The ACE Measure™ consists of four scales:
 Commitment: confidence and ability to maintain a healthy lifestyle and manage one’s health.
 Ownership: perceived role in and responsibility for one’s health.
 Informed Choice: patterns of seeking and using information about health and healthcare.
 Navigation: confidence and ability to ask about and participate in treatment decisions.
The scales are predictive of important outcomes, including patient health, self-reported medication adherence, and use of online decision tools.
