Factor Structure of the Neurocognitive Battery in a Geriatric Sample with Cognitive Impairments

The present study was designed to empirically validate six theoretically derived cognitive domains (verbal memory, visual memory, working memory, attention-concentration, executive functions, and visuospatial abilities) assessed by a comprehensive battery of neuropsychological tests used in the Geriatric Memory Clinic at the University of North Texas Health Science Center in Fort Worth, Texas. The study examined the extent to which various cognitive dimensions are tapped by this battery in a heterogeneous geriatric sample of 114 patients with cognitive impairments. The proposed six-factor model of cognitive functioning has not been supported. Further exploratory factor analysis arrived at a five-factor solution. Factor pattern of the 23 tests supported the following five dimensions: memory, executive control, attention, visuospatial abilities, and cognitive flexibility.
