The inclusion criteria were: Ongoing additional criteria validity studies should complete the measurement equivalence of the Brazilian version of the cakcog. Instrument application and the evaluated variables The test application was done by one of the five trained examiners for the study: These findings corroborate those of Lindeboom et al.

The data suggest that the studied phenomenon – cognition – was kept stable during the period of time in which it was studied. A research team examined the records of the subjects who would be treated and selected those who fulfilled the eligibility criteria.

The exclusion criteria were: 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 data was typed and analyzed using SPSS The internal consistency of the set of items of the test was high: The subscale means were similar in the two testings; a discreet difference was noticed in the “executive functions” subscale and in the MMSE.

It is made up of items which require the copying of drawings and the producing of a freehand drawing of a clock without copying. There was no significant range in the stability of the instrument in sex, age, schooling, or the presence of dementia. When evaluating the stability of an instrument, it 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.

Age Ageing ; J Psychiatr Res ; 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.


The measurement of observer agreement for categorical data. Int J Geriatr Psychiatry ; The internal consistency for the set of items in the test was 0.

Landis J, Koch G. The test application was done by one of the five trained examiners for the study: The intraclass coefficient for the set of items and for the subscales varied from 0.

The stability of the instrument with time did not vary between males and females and or with or without dementia.

Manos PJ, Wu R. The diagnosis of dementia was given by the geriatrician who assisted the subject based on DSM-IV criteria. On retest invitation out of subjects returned. Received 16 December Among the brief neuropsychological batteries mentioned in the literature, the Cambridge Cognitive Examination CAMCOG trst the advantage of offering a summary measurement of the global cognitive function, ttest changes at cutoff score according to age and schooling 3,4.

Ageing Neuropsychol Cognition ;3: Caution must therefore be taken when using the CAMCOG or any other cognitive test as a screening test for dementia, using a single, predetermined cutpoint. Another source of variability which may risk the stability of an instrument is the change of the studied phenomenon.

The ICC score was excellent for the set of items of the test and for the items of the subscales; it varied from “moderate” 0. On the appointment day, the selected subjects were invited to participate in the study. J Intern Neuropsychol Soc ; This finding can be partially explained by the fact that the punctuation of the items which constitute the subscale depends on the raters’ interpretation.

The objective of the present camcoy 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 camcoog psychometric properties of this instrument.

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. In general, the combination of brevity and breadth of the CAMCOG, along with its distributional properties, makes it an attractive neuropsychological tfst for use in the community or the clinic.



The raters were not allowed to discuss their doubts, which were answered later by the coordinator of the survey. Arch Clin Neuropsychol ; However, we suggest reapplying this study in different operational settings to learn about the stability of the instrument in other circumstances. Br J Psychiatry ; It has incorporated a few screening instruments for cognitive disturbances widely used in epidemiological research, such as the Mini-Mental State Examination MMSE 6and 8 of the 10 items of the Hodgkinson Abbreviated Mental Camfog 7.

Results from the Tst Harmonization Project for instruments in dementia. For the interpretation of values, the criteria proposed by Landis and Kock 22 were taken into consideration: The Cambridge examination for mental disorders of the elderly. The stability of the instrument among those with mild, moderate and severe dementia was 0.

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

In the retest, the mean time was 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 during 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 of the test-retest.

Bearing in mind 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. The source population was composed of 1, elders who attended the clinic between May 2 nd and December 28 th The lack of a specific biological marker for the diagnosis of dementia in the clinical practice amplifies the vitality of this evaluation 2.
