One aspect has to do with the raters who, aware of the evaluation process in course, tend to proceed more rigorously than in everyday circumstances, which may provide for an overestimation of the reliability results. The diagnosis of dementia was given by the geriatrician who assisted the subject based on DSM-IV criteria.

It was administered to camcot population sample of elderly people aged 77 and above in their place of residence. Br J Psychiatry ; The inclusion criteria were: Ageing Neuropsychol Cognition ;3: A few general methodological aspects deserve comments when examining the reliability of a rating process, principally of the interrater type. There was no significant range in the stability of the instrument in sex, age, schooling, or the presence of dementia.

Heinik J, Solomesh I. The lack of a specific biological marker for the diagnosis of dementia in the clinical practice amplifies the vitality of this evaluation 2. According to the dementia diagnosis, camcoog “perception” and “executive functions” subscales obtained a higher ICC among the non-cases, while in the “attention and calculation” subscale, the ICC was higher among the cases Table 4.

Criterion-referenced validity of a neuropsychological test battery: Another source of variability which may risk the stability of an instrument is the change of the studied phenomenon.

For the interpretation of values, the criteria proposed by Landis and Kock 22 were taken into consideration: However, we suggest reapplying this study in different operational settings to learn about the stability of the instrument in other circumstances.


The stability of the instrument among those with mild, moderate and severe dementia was 0. All subjects underwent a comprehensive geriatric assessment consisting of a functional and a cognitive evaluation, as well as of an interview cxmcog an informant. The exclusion criteria were: There was no expressive range in the stability of the instrument for sex, age, schooling, or for the presence of dementia.

The data was typed and analyzed using SPSS Among the brief neuropsychological batteries mentioned in the literature, the Cambridge Camog Examination CAMCOG has the advantage of offering a summary measurement of the global cognitive function, allowing changes at cutoff score according to age and schooling 3,4.

J Intern Neuropsychol Soc ; Cambridge University Press, Although there is no standard neuropsychological test for the diagnosis of dementia, exists several instruments used for this purpose. The functional evaluation consisted of applying both the evaluation scale of the daily life basic activities 17 and of the daily life instrumental activities 18both in the subject as well as in the informant, with divergencies in the information written down and commented by the rater.

Rio de Janeiro, These findings corroborate those of Lindeboom et al. The Br-CAMCOG-R has obtained a high level of stability with time, agreement trst raters, and optimum internal consistency; it can be useful for epidemiological studies and in specialized clinics to evaluate cognitive functions in elders. Manos PJ, Wu R. The patient’ schooling was defined as completed years of school in the formal educational system as informed by the subject failed school years were not taken into consideration.

The stability of the total score of the instrument in time was adequate, even after the stratification by sex, age, schooling, and the presence of dementia; the difference in the ICC scores for the test’ set of items tedt for most subscales was discreet, suggesting the instrument maintains its stability in time even in subjects with cognition impairment.

As for the evaluation of the interrater reliability, two raters applied the test and both of them wrote down the answers separately. The operational difficulties camcoog the interrater reliability study, which demanded the presence of two raters in the interview room at the same time, caused the studied sample to be smaller than that cacog the test-retest.

The objective of the present study is to evaluate the interrater reliability and test-retest as well as the internal consistency of the Br-CAMCOG-R, as one of the vital steps in the evaluation process of the psychometric properties of this instrument. Landis J, Koch G.

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

The source population was composed of 1, elders who attended the clinic between May 2 nd and December 28 th Evaluation of a 10 question mental test of the institutionalized elderly. The subscale means were camocg in the two testings; a discreet difference was noticed tes the “executive functions” subscale and in the MMSE.

The data suggest that the studied phenomenon – cognition – was kept stable during the period of time in which it was studied. J Psychiatr Res ; J Geriatr Psychiatry Neurol ; However, a small difference was found for subjects with low schooling Table 4.
