Among the brief neuropsychological batteries mentioned in the literature, the Cambridge Cognitive Examination CAMCOG has the advantage camco offering a summary measurement of the global cognitive function, allowing changes at cutoff score according to age and schooling 3,4. The source population was composed of 1, elders who attended the clinic between May 2 nd and December 28 th The overall mean in the retest was discreetly higher than in the test, which showed a possible learning effect, already noticed in similar studies with different cognitive instruments Accepted 24 March It also allows comparisons between different populations, therefore helping to standardize procedures in clinical and epidemiological studies 1.
This study took place in a public geriatric outpatient clinic in Rio de Janeiro, Brazil.
The Cambridge examination for mental disorders of the elderly. O alfa de Cronbach para o conjunto dos itens do teste foi alta 0, In the test-retest study, analyses were made after sample stratification by sex, age, schooling, and the presence of dementia. The praxis subscale demonstrated the smallest stability in time Table 4. The first 60 subjects tested were also used to assess the interrater reliability of the instrument.
The subscale means were similar in the two testings; a discreet difference was noticed in the “executive functions” subscale and in the MMSE. The ICC camcoog was excellent for the twst of items of the test and for the items of the subscales; it varied from “moderate” 0.
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 and for most subscales was discreet, cqmcog the instrument maintains its stability in time even in subjects with cognition impairment.
The internal consistency of the set of items of the test was high: On retest invitation out of subjects returned. Heinik J, Solomesh I.
Other study limitations were that most of the subjects had low schooling, were under 85 years old, and attended a public health clinic, making the sample a homogeneous one, but not representative of the Brazilian elderly population as a whole. Results from the European Harmonization Project for instruments in dementia.
The fundamental psychometric status of neuropsychological batteries. Rio de Janeiro, The objective of the present study is to evaluate the interrater reliability and test-retest as well as the tets consistency of the Br-CAMCOG-R, as one of the vital steps in the evaluation process of the psychometric properties of this fest.
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. However, it does not seem to us that this fact jeopardized the quality of the results, since similar studies were made with samples containing 40 to 55 subjects 8, Of the eight major subscales orientation, language, memory, attention, praxis, calculation, abstract thinking, perceptionage was significantly related to all but attention; sex with attention, praxis, calculation and perception; education with language and abstract thinking; and social class with language and perception.
Reliability of the Brazilian version of the Cambridge Cognitive Examination Revised CAMCOG-R
In Brazil, the only study found by the authors which validates instruments from this country’ perspective was the one written by Bottino et al. In all these analyses, the results were adjusted for the effects of the other socio-demographic variables using analysis of variance. Arch Fest Neuropsychol ; There was no significant range in the stability of the instrument in sex, age, schooling, or the presence of dementia.
Cancog J Psychiatry ; Although there is no standard neuropsychological test for the diagnosis of dementia, exists several instruments used for this purpose. Ageing Neuropsychol Cognition ;3: A few general methodological aspects deserve comments when examining the reliability of a rating process, principally of the interrater type.
Clinical and neuropsychological assessment of Alzheimer’ disease. Test-retest reliability In the test-retest reliability study, J Geriatr Psychiatry Neurol ; The high interrater reliability found in the present study suggests that, despite its complexity and the dependence on the raters’ evaluation of some items, the variability associated to the rater did not jeopardize the instrument’ reliability.
Discreet differences were noticed in the ICC values for the subscale items after sex, age, and schooling stratification. The age taken into consideration was based on any identification document presented, and it was divided into: 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 Test 7.
The stability of the instrument with time did not vary between males and females and or with or without dementia.

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 testing took place in a reserved room, well lit, with little external noise, and with no visible calendars or clocks. Camcig hundred and twenty-three subjects took part in the test-retest study, while 60 of them participated in the interrater reliability study as well.
On the appointment day, the selected subjects were invited to participate in the study. The stability of the instrument among those with mild, moderate and severe dementia was 0.
These findings corroborate those of Lindeboom et al. The intraclass coefficient for the set of items and for the subscales varied from 0. A research team camcot the records of the subjects who would be treated and selected those who fulfilled the eligibility criteria. Neuropsychological batteries of tests are widely used to evaluate subjects who tested positive in the screening examinations.
