The Comprehensive Geriatric Assessment is characterized as a functional and interdisciplinary evaluation. The first step is the assessment of functional status, which lies at the core of the procedure and can be defined by the level at which an individual performs roles and activities of daily living. Such assessment can be carried out by instruments (questionnaires) whose conceptual framework and psychometric properties must be well-defined. The present study systematically reviewed published data on the properties of the functional status measurement instruments and their adaptation and use in Brazil, through a search of the medical literature in reference textbooks and the LILACS and MEDLINE databases. After selection of the instruments, the next step consisted of a systematic scrutiny of validation, replication, and cultural adaptation studies. Thirty instruments were included according to explicit criteria. Only two, the Medical Outcomes Study SF-36 and the Health Assessment Questionnaire, were found to have equivalence studies in Brazil. However, some of these were apparently used in this country without any formal adaptation. The cultural adaptation of functional status measurement instruments is incomplete and inconsistent in Brazil.

Este artigo descreve a adaptação transcultural para uso no Brasil do instrumento Hwalek-Sengstock Elder Abuse Screening Test (H-S/EAST) utilizado para identificar risco de violência doméstica em idosos. Avaliando-se as equivalências conceitual e de itens, concluiu-se pela pertinência delas no contexto brasileiro. A equivalência semântica contemplou a correspondência de significado referencial/denotativo de termos e a geral/conotativa dos itens em si. A equivalência de mensuração foi investigada por intermédio de propriedades psicométricas. Semelhante ao encontrado no instrumento original em inglês, a análise fatorial revelou três dimensões. Seis dos sete itens carregaram satisfatoriamente no fator 1 (escala de "situação de abuso potencial"). A consistência interna mostrou-se razoável e reprodutibilidade intra-observador discreta. O segundo fator representando a dimensão de "violação de direitos pessoais ou abuso direto" teve desempenho semelhante. Ainda assim, identificou-se troca de itens entre estas escalas e cargas cruzadas. Uma terceira escala que deveria abarcar as "características de vulnerabilidade" não teve o mesmo desempenho. Conclui-se que mesmo sem mostrar equivalência completa, o H-S/EAST já poderia ser recomendado para uso no contexto brasileiro, pelo menos em parte.

This study aimed to evaluate the prevalence of thyroid dysfunction in elderly subjects attending an outpatient clinic at a tertiary hospital and to assess whether subclinical hypothyroidism (SCH) or aging affected activities of daily living (ADLs), instrumental activities of daily living (IADLs), cognitive status, or depressive symptoms. This crosssectional study included 411 patients recruited in the outpatient geriatric setting. 48 subjects reported levothyroxine use and were evaluated separately. After excluding subjects with diseases or drugs which could influence thyroid status, the 284 subjects remaining were classified as having euthyroidism (n = 235, 82.8 %), subclinical hypothyroidism (n = 43, 15.1 %), subclinical hyperthyroidism (n = 4, 1.4 %), or overt hyperthyroidism (n = 2, 0.7 %). ADLs and IADLs were assessed using the Katz Index (ranging from 0 [independence] to 6 [dependence in all activities]) and Health Assessment Questionnaire (ranging from 0 to 3 [severely disabled]), respectively. Cognition was assessed using the mini mental state depressive symptoms that were assessed using the Geriatric depression scale or cornell scale for depression in dementia. SCH did not reduce performance in ADLs or IADLs in elderly subjects as a whole, but was an independent protective factor against dependence in ADLs (OR = 0.196 [0.045–0.853]; p = 0.003) and IADLs (OR = 0.060 [0.010–0.361]; p = 0.002) in subjects aged ≥85 years. Very old subjects with SCH showed better performance in ADLs than did those with euthyroidism (Katz Index: 0.9 ± 1.6 [median: 0.5] vs. 1.7 ± 1.7 [1.0], p = 0.024; HAQ: 1.2 ± 0.8 [0.9] vs. 1.8 ± 1.0 [1.9], p = 0.015). This putative protective effect of SCH was not found in subjects aged <85 years. The number of falls, number of medications used, depressive symptoms, and cognitive impairment did not differ among thyroid status groups, regardless of age. In conclusion, SCH does not have impact functional performance in the elderly population as a whole, but was associated with better functional status in subjects aged ≥85 years.
