Summary
The Cognitive Screening Test (CST14) has four factors related to general knowledge and orientation. Cognitive function tests explained 55% of CST14 variance, highlighting episodic memory preservation in some patients.
Area of Science:
- Gerontology
- Neuropsychology
- Cognitive Science
Context:
- The study investigated the factorial structure of the Cognitive Screening Test (CST14) in elderly individuals attending a psychogeriatric day care center.
- Participants included 106 individuals (75 women, 31 men) with a mean age of 77.7 years.
Purpose:
- To analyze the factorial structure of the CST14.
- To examine the relationship between CST14 scores and various cognitive functions.
Summary:
- Factor analysis of CST14 scores revealed four principal components explaining 66% of the variance, reflecting knowledge of current/last queen, orientation to date/day/age/time, date of birth, and home address.
- A stepwise regression model indicated that episodic recall, episodic recognition, confrontation naming, and category fluency explained 55% of CST14 variance.
- Visual and visuospatial perception measures did not contribute explanatory variance to CST14 scores.
Impact:
- The findings suggest that dissociations within the CST14 can reveal individual cognitive profiles, showing impaired and intact functions.
- Specifically, preserved episodic memory, such as orientation to date, may be observed in aphasic patients, offering insights for targeted interventions.
