RESUMEN
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.
