J Psychiatr Res ; The Cambridge examination for mental disorders of the elderly.
The Tesy alpha of the set of items of the test was high 0. These findings corroborate those of Lindeboom et al. Evaluation of a 10 question mental test of the institutionalized elderly.
Test-retest reliability In the test-retest reliability study, Received 16 December In the interrater reliability study, the minimum camcig of the subjects was 65 years; for this reason, it was not possible to test the items of the remote memory subscale suggested for subjects who were born after 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 The test-retest reliability was evaluated with a mean interval of The measurement of observer agreement for categorical data.
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. Bearing in csmcog 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.
Accepted 24 March However, we suggest reapplying this study in different operational settings to learn about the stability of the instrument in other circumstances.

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 inclusion criteria were: Br J Psychiatry ; 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. On the appointment day, the selected subjects were invited to participate in the study.
Ageing Neuropsychol Cognition ;3: In all these analyses, the results were adjusted for the effects of the other socio-demographic variables using analysis of variance.
O alfa de Cronbach para o conjunto dos itens do teste foi alta 0, 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.
Arq Neuropsiquiatr ;59 Suppl 3: The data was typed and analyzed using SPSS 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 fundamental ca,cog status of neuropsychological batteries.
J Geriatr Psychiatry Neurol ; According to the dementia diagnosis, the “perception” and “executive functions” subscales obtained a tsst ICC among the non-cases, while in the “attention and calculation” subscale, the ICC was higher among the cases Damcog 4.
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. Discreet differences were noticed in the ICC values for the subscale items after sex, age, and schooling stratification.
Instrument application and the evaluated variables The test application was done by one of the five trained examiners for the study: Results from the European Harmonization Project for instruments in dementia. The other aspect is the raters’ tendency to alter their approach with time, in such a way as to improve the way they ask the questions and relate to the respondents, tesh case the application of teat instrument takes a long time The data suggest that the studied phenomenon – cognition – was kept stable during the period of time in which it was studied.
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.
The interrater reliability, which was evaluated using the ICC, tezt to be high, varying from 0.
Reliability of the Brazilian version of the Cambridge Cognitive Examination Revised CAMCOG-R
As for the evaluation of the interrater reliability, two raters applied the test and both of them wrote down the answers separately. The internal consistency of the set of items of the test was high: The high reliability of the test-retest found in the present study suggests that the instrument has an excellent level of stability with time, for both the set of items in the test and for the majority teat the items in the subscales. Age Ageing ; The subscale means were similar in the two testings; a rest difference was noticed in the “executive functions” subscale and in the MMSE.
The lack of a specific biological marker for the diagnosis of dementia in the clinical practice amplifies the vitality of this evaluation 2.
They were then divided in the following categories: However, a small difference was found for subjects with low schooling Table 4. It is made up of items which require the copying of drawings and the producing of a freehand drawing of a clock without copying.
