Application of Ecological Momentary Assessment in Symptom Management among Middle‑Aged and Older Adults with Coronary Heart Disease:A Scoping Review

This scoping review aims to map the existing evidence on the application of EMA in symptom management among middle-aged and older adults with CHD. Specifically, it will: (1) describe the volume, study designs, geographical distribution, and participant characteristics of the literature; (2) characterise EMA implementation modalities, including delivery methods, sampling schedules, assessment frequency, duration, and feedback mechanisms; (3) summarise the symptoms assessed, symptom-related outcomes, and reported findings; (4) examine adaptations addressing the needs of middle-aged and older adults; and (5) identify evidence gaps and implications for future research, clinical practice, and policy. The findings will provide a foundation for developing age-appropriate and context-sensitive EMA approaches to symptom management in middle-aged and older adults with CHD.
