Abstract text:
With rapid global population aging, preventing cognitive decline in later life has become a priority. Although well-being serves as a protective factor for cognitive functioning, its components may exert differential effects, underscoring the need for interventions adapted to specific domains. In addition, subjective memory decline (SMD)—a self-assessable early indicator of cognitive impairment—represents a critical focus for timely prevention. Ecological momentary assessment (EMA) offers a valuable approach to capturing the relationships between well-being components and SMD in daily life.


Purpose: This study aimed to develop and evaluate the feasibility of a mobile-based EMA protocol assessing well-being predictors of SMD among Korean older adults.


Method: A preliminary survey of 43 Korean older adults aged 65-85 assessed well-being and SMD; correlations informed EMA survey development. The protocol was developed per EMA guidelines and refined based on feedback from two older adults. The feasibility study involved 10 different participants (six young-old [65-74] and four old-old [75-85]), including daily surveys over 14 days and follow-up evaluations. The protocol was refined through the researchers' synthesis and finalized.


Results: Preliminary analyses revealed negative correlations between SMD, overall well-being, and several of its components. In the EMA feasibility study, one old-old participant missed three surveys, while others completed all surveys. All participants received initial assistance; old-old participants additionally required occasional remote support. Response times decreased from 6.3 minutes on Day 1 to 3.3 minutes on Day 14, and participants rated feasibility highly across five domains—technical convenience, item comprehensibility, schedule appropriateness, support, and engagement (M = 4.58/5). Researchers' synthesis yielded 13 practical considerations for final protocol refinement across survey administration, interface design and item clarity, and participant management.


Conclusions: Findings demonstrate the feasibility of EMA for assessing well-being predictors of SMD. This protocol is practical and may offer a scalable tool for early detection, timely prevention, and targeted intervention in Korean older adults.
