Screening for dementia: Brazilian version of the Informant Questionnaire on Cognitive Decline on the Elderly and its psychometric properties

Abstract

This study suggests that the IQCODE-BR is a valid tool for screening of dementia and that IQCODE-BR scores do not seem to be influenced by age, educational level and other factors associated with the informants. However, further studies are required to evaluate informant characteristics, such as anxiety states, depression and burden level.

Fragilidade em Idosos Brasileiros - Fibra-RJ: metodologia de pesquisa dos estudos de fragilidade, distúrbios cognitivos e sarcopenia

“…O estudo FIBRA-RJ, deu origem a uma série de artigos, dissertações de mestrado e teses de doutorado. 3,12,[28][29][30][31][32][33][34][35][36] Discussão O estudo FIBRA-BR, por seu delineamento multicêntrico, provavelmente representou um dos esforços mais abrangentes de pesquisadores brasileiros, para a compreensão da dimensão da fragilidade e seus fatores associados, em território nacional. O segmento Rio de Janeiro desse estudo, o FIBRA-RJ, representou uma tentativa de ir além dos objetivos inicialmente traçados, e dar continuidade ao acompanhamento da amostra examinada, investigando outros aspectos de acometimento de saúde, bastante comuns entre a população idosa, e ainda carentes de estudos populacionais com um número substancial de indivíduos.…”

Accuracy of the Brazilian version of the Functional Activities Questionnaire in the screening of dementia

“…The IQCODE-BR scores range from zero to 130, and the final score is obtained by adding the values of all the answers to the items, divided by the total number of items. Therefore, low final scores indicate the absence of cognitive deficit (Lourenço & Sanchez, 2014;Sanchez & Lourenço, 2013). It is worth highlighting that the normal distribution of data was tested and confirmed, which enabled the use of the Pearson correlation coefficient.…”

“…Scores on the FAQ-BR showed high and statistically significant correlations with scores on the MMSE and the IQCODE-BR. The MMSE is the screening tool for cognitive decline and dementia most widely used in epidemiological studies and showed adequate diagnostic qualities in its validation study for use in Brazil (Lourenço & Veras, 2006), as did the IQCODE-BR (Lourenço & Sanchez, 2014;Sanchez & Lourenço, 2013), also used to detect cognitive decline in the elderly, but based on the informant's report. In light of this, it is possible to state that the FAQ-BR, although it did not demonstrate suitable validity of predictive criteria for dementia, it did show suitable concurrent validity when compared to other tools for screening cognitive decline and/or dementia -based on the report of an informant or not -already validated and in established use in Brazil.…”

“…The following information of the elderly was considered, collected from questions asked in personal interviews of the FIBRA-RJ baseline: gender (male or female); age (in years); education (in years of study); and MMSE results (in points). Moreover, other data from the second stage of the FIBRA-RJ was also considered: the result of the validated Brazilian version of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE-BR; Lourenço & Sanchez, 2014;Sanchez & Lourenço, 2013) administered to the informant in a personal interview (in points); and, the clinical diagnosis of dementia (present or absent), based on the consensus between a neuropsychologist -who administered various cognitive and functional evaluation tests -and two geriatricianswho evaluated medical history and physical, laboratory and imaging exams (MRI of the brain). The clinical diagnosis of dementia was established after two meetings of consensus following a standard protocol that considered the criteria in the Diagnostic and Statistical Manual of Mental Disorders IV (American Accuracy of the Brazilian version of the Functional Activities Questionnaire in the screening of dementia Psychiatric Association [APA], 2000).…”
