Factor structure of the Neurobehavioral Cognitive Status Exam (COGNISTAT) in healthy, and psychiatrically and neurologically impaired, elderly adults.
This study reports the results of factor analyses of COGNISTAT (NCSE) in a sample of elderly persons comprised of "healthy" participants with no psychiatric or neurological impairments (n = 153), individuals with psychiatric impairments (n = 70), and those with neurological impairments (n = 80). Our findings support a unitary factor structure for COGNISTAT, though a separate factor of unclear clinical or theoretical significance was suggested.
