Reliability of the Brazilian version of the Cambridge Cognitive Examination Revised CAMCOG-R

Abstract

The study' goal was to evaluate the reliability of the Cambridge Cognitive Examination Revised-Brazilian version (Br-CAMCOG-R), a neuropsychological battery measuring the global cognitive function. It was applied on 123 elders and retested at a mean interval of 30.7 days; 60 were evaluated by two raters at the same time. The intraclass coefficient for the set of items and for the subscales varied from 0.93 to 0.98. In the retests the agreement was nearly perfect for the set of items. There was no expressive range in the stability of the instrument for sex, age, schooling, or for the presence of dementia. The Cronbach' alpha of the set of items of the test was high (0.89). The Br-CAMCOG-R has obtained a high level of stability with time, agreement among raters, and optimum internal consistency; it can be useful for epidemiological studies and in specialized clinics to evaluate cognitive functions in elders.

The CAMCOG for patients with Alzheimer's disease with low levels of education

“…This concept makes clear that the validation process is not to be concluded following an initial translation and reliability study, but rather is the final product of hard scientific work. We think that the cited papers of Bottino et al (2001) and Paradela et al (2009), along with a few other recently published methodological works, fail to fulfill the required criteria that would allow us to conclude that the task is finished.…”

Is the Cambridge Cognitive Examination - Revised a good tool for detection of dementia in illiterate Brazilian older adults?

“…This is the latest version of the CAMCOG, and is part of the Cambridge Examination for Mental Disorders of the Elderly‐Revised . The CAMCOG‐R is a brief neuropsychological battery formerly designed to be used in individuals with positive results in screening tests for cognitive deficits .

“…1 The CAMCOG-R is a brief neuropsychological battery formerly designed to be used in individuals with positive results in screening tests for cognitive deficits. [2][3][4] It has incorporated a few preexisting screening instruments for cognitive decline, widely used in epidemiological research, such as the Mini-Mental State Examination, 5 and eight of the 10 items of the Hodgkinson Abbreviated Mental Test. 6 The CAMCOG-R is subdivided into eight subscales, which assess different cognitive domains: orientation (time and place), language (comprehension and expression), memory (incidental, remote, recent and new learning), attention, calculation, praxis, perception and executive functions (abstract thinking, ideational fluency and visual reasoning).…”
