Background and Purpose : Although the 15-item Geriatric Depression Scale (GDS15) is a widely used depression screening questionnaire, the implications of the GDS15 in patients with Alzheimer¡¯s disease (AD) are questionable. We designed this study to explore the GDS15 factor structure and the relationships between these factors and cognitive-behavioral aspects.
Methods :The GDS15, cognitive function tests, and the Korean-Neuropsychiatry Inventory were administered to 310 patients with probable AD, who were not medicated before visiting the hospital. Three factors were identified by principal components analysis. A bivariate correlation analysis was conducted to determine the relationships between factors and neurocognitive and behavior symptoms.
Results : Factor 2 was correlated with the Korean Boston Naming Test, calculating ability, the go-no-go test, the Controlled Oral Word Association Test (COWAT), the Color Word Stroop Test (CWST; words and color), aggression, depression, and apathy. Factor 3 was correlated with calculating ability, the Seoul Verbal Learning Test, immediate recall, copy, and delayed recall on the Rey-Osterieth Complex Figure Test, contrasting on the COWAT, and words and delusion on the CWST. We identified three factors and revealed that the GDS15 may be comprised of a heterogeneous scale.
Conclusions : These results suggest that the GDS15 may be comprised of a heterogeneous scale and suggest multi-dimensional properties of the GDS15 in patients with AD.
