The National Alzheimer’s Plan calls for improving health care for people living with dementia and supporting their caregivers as capable health care partners. Clinically useful measurement tools are needed to monitor caregivers’ knowledge and skills for managing patients’ often complex health care needs as well as their own self-care. We created and validated a comprehensive, caregiver-centered measure, Managing Your Loved One’s Health (MYLOH), based on a core set of health care management domains endorsed by both providers and caregivers. In this article, we describe its development and preliminary cultural tailoring. MYLOH is a questionnaire containing 29 items, grouped into six domains, which requires <20 min to complete. MYLOH can be used to guide conversations between clinicians and caregivers around health care management of people with dementia, as the basis for targeted health care coaching, and as an outcome measure in comprehensive dementia care management interventions.
