Abstract

OBJECTIVES: To establish a theoretically justified factor structure for the Addenbrooke's Cognitive Examination-Revised (ACE-R). METHODS: Our sample comprised 288 patients with Parkinson's disease (179 men and 109 women). The mean age of participants was 66.66 (SD = 8.93). Confirmatory factor analysis (CFA) was used to evaluate the test developers' five-factor model of the ACE-R, and alternative models as guided by the Cattell-Horn-Carroll (CHC) theory. Exploratory structural equation modeling (ESEM) was also employed to examine alternative factor structures to ensure that a good candidate model was not overlooked. RESULTS: A three-factor CHC-guided CFA and a similar three-factor ESEM model ..
