Factor analysis of the Cognitive Abilities Screening Instrument: Kuakini Honolulu-Asia Aging Study.

ABSTRACT:

Objective

The Cognitive Abilities Screening Instrument (CASI) is a screening test of global cognitive function used in research and clinical settings. However, the CASI was developed using face validity and has not been investigated via empirical tests such as factor analyses. Thus, we aimed to develop and test a parsimonious conceptualization of the CASI rooted in cognitive aging literature reflective of crystallized and fluid abilities.

Design

Secondary data analysis implementing confirmatory factor analyses where we tested the proposed two-factor solution, an alternate one-factor solution, and conducted a χ² difference test to determine which model had a significantly better fit.

Setting

N/A.

Participants

Data came from 3,491 men from the Kuakini
