ENGLISH AND SPANISH ASSESSMENT OF COGNITION IN ELDERLY

Project: Research project

Project Details

Description

The purpose of this research is to develop a multidimensional
psychometric test instrument to assess cognitive functioning in the
elderly which will have equivalent English and Spanish versions.
Statistical methods associated with Item Response Theory (IRT) will be
used for test development, and an important goal of this project will be
to test the efficacy of these methods for multilingual neuropsychological
test development. Homogeneous scales which assess broad ability ranges
applicable to both patients with moderately severe dementia and high
functioning normals will be developed. The scales will measure 12
abilities that have been shown to be important in neuropsychological and
cognitive research with the elderly. Scales will be matched according to
important psychometric characteristics to facilitate assessment of
differential patterns of cognitive deficit independent of psychometric
artifact. IRT procedures will be used in test construction to minimize
cultural and language bias of items and to construct provisional norms
for the final scales. Test development will be based upon a sample of
400 normal elderly (200 English speaking and 200 Spanish speaking). In
addition, a group of dementia patients and a group of high functioning,
non-elderly normals will be used to assure that items are included which
will provide low and high end discrimination for all of the abilities
assessed. This will be a three year project. Item development and pilot
testing will occur during months 1 to 6. Recruitment and testing of the
normal elderly derivation. sample will occur during months 7 to 30.
Statistical analysis, item selection, calculation of provisional norms,
and evaluation of efficacy of test development procedures will be
completed during months 31 to 36.
