Area of Science:

  • Gerontology
  • Cognitive Science
  • Psychometrics

Background:

  • Subjective cognitive decline (SCD) is a key aspect of aging and a potential indicator of neurodegenerative diseases.
  • Traditional SCD measures rely on retrospective recall, which can be limited.
  • Ecological momentary assessment (EMA) offers a promising alternative for real-time symptom tracking.

Purpose of the Study:

  • To develop and pilot test the mobile Everyday Cognition Scale (mECog) for assessing SCD.
  • To evaluate the feasibility, acceptability, and psychometric properties of the mECog.

Main Methods:

  • 31 community-dwelling older adults participated in the study.
  • Participants completed in-lab cognitive and mental health assessments.
  • Daily mECog ratings were collected via smartphone over 28 days.

Main Results:

  • The mECog demonstrated high participant adherence (87%) and was rated as easy to use.
  • Strong test-retest reliability (R = .99) and moderate within-person reliability (R = .41) were observed.
  • mECog scores showed strong convergent validity with existing ECog measures and non-significant associations with demographics and mental health symptoms.

Conclusions:

  • Mobile assessment of SCD using the mECog is feasible and acceptable for older adults.
  • The mECog exhibits robust psychometric properties, including reliability and validity.
  • The mECog represents a valuable tool for advancing SCD research and clinical assessment.
