Reasoning Test The ART was developed by Embretson (1995) using the cognitive design system approach. ART items are matrix completion problems. Matrix completion problems appear on a variety of intelligence and ability tests. They are considered a stable measure of fluid intelligence (Raven, 1965). Construct Validity and Cognitive Diagnostic Assessment 133 Embretson (1995, 1998) further develope...

The purpose of this study was to determine whether (1) mild cognitive impairment (MCI) alters the validity of the Timed Up and Go (TUG), the 8-Foot Up and Go (8UG), or the Activities-Specific Balance Confidence (ABC) scale in the identification of fallers and nonfallers and (2) there were differences in the concurrent validity between the TUG and ABC when compared with the 8UG and ABC in those ...

This study was an attemptto provide detailed information of the strengths and weaknesses of test takers‟ real ability through cognitive diagnostic assessment, and to detect differential item functioning in each test item. The rationale for using CDA was that it estimates an item‟s discrimination power, whereas clas- sical test theory or item response theory depicts between rather within item mu...

Question In adults with cognitive impairment or memory problems how effective is the MoCA (Montreal Cognitive Assessment) compared to the MMSE (Mini Mental State Examination) in memory management / managing cognitive impairment? Evidence from six diagnostic test accuracy studies indicated that the MoCA is likely to perform as well as or better than the MMSE for the diagnosis of cognitive impair...

BACKGROUND Trends in medical education have reflected the patient safety movement's initial focus on systems. While the role of cognitive-based diagnostic errors has been increasingly recognised among safety experts, literature describing strategies to teach about this important problem is scarce. METHODS 48 PGY-2 internal medicine residents participated in a three-part, 1-year curriculum in ...

Early and accurate diagnosis of dementia is key to appropriate treatment and management. Clinical assessment, including the use of cognitive screening instruments, remains integral to the diagnostic process. Many cognitive screening instruments have been described, varying in length and hence administration time, but it is not known whether longer tests offer greater diagnostic accuracy than sh...

Within the professional literature, it is frequently suggested that interpretation of cognitive profile scatter may be useful for clinical and/or diagnostic decision-making. To wit, Hale and colleagues (2008) posit that cognitive scatter is a defining characteristic of learning disabilities and that individuals with learning disabilities may have higher levels of scatter than normal controls. T...
