When evaluating the stability of an instrument, camckg is fundamental to guarantee that the variability of the results is not significantly determined by the range associated to the rater, which can occur due to the precarious standardization while applying it.
In the test-retest study, analyses were made after sample stratification by sex, ttest, schooling, and the presence of dementia. The instrument is composed of 69 items with a maximum score of points; the higher the total score, the better the performance in the test. The use of reliable and valid instruments to evaluate cognition of the elderly with memory complaints provides more accurate and reproductive diagnosis, making it possible for the health professional to be able to trace therapeutic goals based on objective results.
The subscale means were similar in the two testings; a discreet difference was noticed in the “executive functions” subscale and in the MMSE. Hest subjects underwent a comprehensive geriatric assessment consisting of a functional and a cognitive evaluation, as well as of an interview with an informant. These findings corroborate those of Lindeboom et al.
However, education and social class are highly correlated variables and when the association with education is examined without adjusting for social class, attention and praxis are also found to be significantly related to education.
Validation of a short cognitive tool for the screening of dementia in elderly people with low educational level. They were then divided in the following categories: Received 16 December Arq Neuropsiquiatr camcov Suppl 3: A few general methodological aspects deserve comments when examining the reliability of a rating process, principally of the interrater type.
The Br-CAMCOG-R has obtained a high level of stability with time, agreement among raters, and optimum internal consistency; it can cacog useful for epidemiological studies and in specialized clinics to evaluate cognitive functions in elders.
One hundred and twenty-three subjects took part in the test-retest study, while 60 of them participated in the interrater reliability study as well. However, we suggest reapplying this study in different operational settings to learn about the stability of the instrument in other circumstances.
In the retest, the mean time was It also allows comparisons between different populations, therefore helping to standardize procedures in clinical and epidemiological studies 1.

Reliability of the Brazilian version of the Cambridge Cognitive Examination Revised CAMCOG-R
However, a small difference was found for subjects with low schooling Table 4. Examination of the association between CAMCOG scores and socio-demographic variables age, sex, education and social class shows that each exerts a significant, and independent, effect upon performance.
Another source of variability which may risk the stability of an instrument is the change of the studied phenomenon. O alfa de Cronbach para o conjunto dos itens do teste foi alta camckg, As the “attention” and the “calculation” subscales are very small each having only two itemsthey were analyzed together with a maximum value of 9 points. Bearing in camcoh the multidimensionality of the construct named cognition, the internal consistency of the instruments used to evaluate it should reflect the agreement or not of each item with the test as a whole.
In general, the combination of brevity and breadth of the CAMCOG, along with its distributional properties, makes it an attractive neuropsychological test for use in the community or the clinic.
Instrument application and the evaluated variables The test application was done by one of the five trained examiners for the study: The first 60 subjects tested were also used to assess the interrater reliability of the instrument. In Brazil, the only study found by the authors which validates instruments from this country’ perspective was the one written by Bottino et al.
According to the teest diagnosis, the “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.
It has incorporated a few screening instruments for cognitive disturbances widely used in epidemiological research, such as trst Mini-Mental State Examination MMSE 6and 8 of the 10 items of the Hodgkinson Abbreviated Mental Test 7. Landis J, Koch G. Instrument application and the evaluated variables.
The intraclass coefficient for the set of items and for the subscales varied from 0. In the retests the agreement was nearly perfect for the set of items.

The interrater reliability, which was evaluated using the ICC, proved to be high, varying from 0. The test-retest reliability was evaluated with a mean interval of RESULTS One hundred and twenty-three subjects took part in the test-retest study, while 60 of them participated in the interrater reliability study as well. The raters were not allowed to discuss their doubts, which were answered later by the coordinator of the survey.
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. Heinik J, Solomesh I. The internal consistency of the set of items of the test was high:
