ABSTRACT OBJECTIVE To establish the diagnostic accuracy of the Brazilian version of the General Practitioner Assessment of Cognition (GPCOG-Br) compared to the Mini-Mental State Examination (MMSE) in individuals with low educational level. METHODS Ninety-three patients (≥ 60 years old) from Brazilian primary care units provided sociodemographic, cognitive, and functional data. Receiver operating characteristics, areas under the curve (AUC) and logistic regressions were conducted. RESULTS Sixty-eight patients with 0–4 years of education. Cases (n = 44) were older (p = 0.006) and performed worse than controls (n = 49) on all cognitive or functional measures (p < 0.001). The GPCOG-Br demonstrated similar diagnostic accuracy to the MMSE (AUC = 0.90 and 0.91, respectively) and similar positive and negative predictive values (PPV/NPV, respectively: 0.79/0.86 for GPCOG-Br and 0.79/0.81 for MMSE). Adjusted cut-points displayed high sensitivity (all 86%) and satisfactory specificity (65%–80%). Lower educational level predicted lower cognitive performance. CONCLUSIONS The GPCOG-Br is clinically well-suited for use in primary care.

Abstract Background Generalized anxiety disorder (GAD) has negative implications for people’s lives, but is often underdiagnosed in the elderly. There is a shortage of instruments to assess geriatric anxiety. Objectives To analyze the applicability and psychometric properties of the Portuguese version of the Geriatric Anxiety Inventory (GAI) and its short form (GAI-SF) within primary care. Methods Fifty-five seniors were classified as non-demented by a multidisciplinary panel. The protocol included the GAI, the Self-Reporting Questionnaire (SRQ-20), the Depression Scale D-10, Mini-Mental State Examination (MMSE), Bayer Scale for Activities of Daily Living (B-ADL) and the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). A sub-sample also completed the Beck Anxiety Inventory (BAI). Results The GAI and GAI-SF showed good internal consistency (0.89; 0.62, respectively) and test-retest stability (0.58, 0.97). The GAI and GAI-SF correlated significantly with the SRQ-20 (0.74, 0.55) and BAI (0.75, 0.58). Discussion The psychometric characteristics of the Brazilian versions of the GAI and GAI-SF suggest these instruments are suitable for application in the Brazilian elderly population within the primary care setting.

A análise do padrão do movimento ocular auxilia discriminar leitores competentes daqueles com dificuldades de leitura. O padrão de leitura dos movimentos oculares é afetado por propriedades psicolingüísticas da palavra, tais como: comprimento, regularidade, freqüência e lexicalidade O objetivo do presente estudo foi analisar o padrão de movimentos oculares durante a leitura em português do Brasil e compará-lo com resultados de estudos de outras línguas. Os movimentos oculares durante a leitura de palavras e pseudopalavras foram analisados em 20 universitários com idade média de 20,5 anos (DP=2,9). Os resultados indicam que o número de fixações, tempo da primeira fixação e tempo total das fixações foram influenciados pelas variáveis, comprimento, lexicalidade e freqüência dos itens. Foi observado efeito de regularidade para todas as variáveis, exceto naquela do número de fixações. Os resultados obtidos foram semelhantes àqueles encontrados em outras línguas com predomínio de palavras regulares, mas não de palavras irregulares, como o inglês.

Analyses of eye movement's pattern contribute significantly to the discrimination between good and poor readers. The pattern of eye movements during reading is affected by psycholinguistic properties of words such as: length, regularity, and frequency. The objective of the present study was to analyze eye movements during words and non-words reading in Brazilian Portuguese and compare the results with the data from other languages. Eye movements during the words and non-words reading were recorded from 20 university students with the mean age of 20.5 years (SD=2.9). Results showed significant effect of word length, regularity and frequency on number of fixations, first fixation duration and gaze duration. Regularity showed effect on all of the variables except on number of fixations. The results are similar to those found in languages with predominantly regular orthographies, but not with the irregular ones such as English.
