Clinical and neuropsychological assessment of Alzheimer’ disease. 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 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 test application was done by one of the five trained examiners for the study: They were then divided in the following categories: This study took place in a public geriatric outpatient clinic in Rio de Janeiro, Brazil.
Instrument application and the evaluated variables The test application was done by one of the five trained examiners for the study: The measurement of observer agreement for categorical data.
Manos PJ, Wu R. A few general methodological aspects deserve comments when examining the reliability of a rating process, principally of the interrater type.
The Cronbach’ alpha of the set of items of the test was high 0.
The testing took place in a reserved room, well lit, with little external noise, and with no visible calendars or clocks. 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.
According to the dementia 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. 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.

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. 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 tesy, but not representative of the Brazilian elderly population as a whole.

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. Accepted 24 March Arch Clin Neuropsychol ; 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 of the items in the subscales.
J Geriatr Psychiatry Neurol ; Results from the European Harmonization Project for instruments in dementia. 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 raters were not allowed to discuss their doubts, which were answered later by the coordinator of the survey. Int J Psychiatry Med ; The source population was composed of 1, elders who attended the clinic cacmog May 2 nd and December 28 th Each subject submitted to the test sat on a chair at a table used as a surface upon which to write or draw, and in case he or she wore eyeglasses, was asked to wear them.
The interrater reliability, which was evaluated using the ICC, proved to be high, varying from 0. Among the brief neuropsychological twst mentioned in the literature, the Cambridge Cognitive 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.
The data was typed and analyzed using SPSS However, we suggest reapplying this study in different operational settings to learn about the stability of the instrument in other circumstances.
Reliability of the Brazilian version of the Cambridge Cognitive Examination Revised CAMCOG-R
It was applied on elders and retested at a mean interval of Rio de Janeiro, 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. There was no expressive range in the stability of the instrument for sex, age, schooling, or for the presence of dementia. 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.
Ageing Neuropsychol Cognition ;3: 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.
