The Self-Administered Gerocognitive Examination (SAGE) effectively screens for cognitive impairment in community settings. This cognitive screening tool is feasible, efficient, and well-balanced across multiple cognitive domains.
Area of Science:
- Gerontology
- Cognitive Neuroscience
- Public Health
Background:
- Cognitive impairment affects a significant portion of the aging population.
- Accessible and efficient cognitive screening tools are needed for early detection.
- Community-based screening can improve access to cognitive health assessments.
Purpose of the Study:
- To evaluate the Self-Administered Gerocognitive Examination (SAGE) for cognitive screening in community settings.
- To assess the psychometric properties of SAGE as a cognitive screening assessment tool.
- To determine the feasibility and efficiency of SAGE in diverse community environments.
Main Methods:
- 1,047 individuals over age 50 were screened using SAGE across 45 community events.
- Principal-component and correlation analyses were employed to examine SAGE's internal consistency and domain balance.
- Data were collected in various community settings, accommodating both small and large groups.
Main Results:
- Cognitive impairment was identified in 28% of the screened individuals.
- SAGE demonstrated strong internal consistency and balanced representation across language, cognition, visuospatial, executive, and memory domains.
- Community cognitive screening with SAGE proved feasible and efficient.
Conclusions:
- SAGE is a reliable and valid tool for cognitive screening in community-dwelling older adults.
- The use of SAGE in community settings facilitates efficient identification of individuals needing further cognitive evaluation.
- SAGE's balanced domain coverage supports its utility in comprehensive cognitive assessment.
