Abstract

Este estudo analisou as propriedades psicométricas da versão em Português Brasileiro do questionário de “Transtorno de Ansiedade Generalizada - GAD-7 em uma amostra de comunidade (n = 206) da população adulta brasileira. A amostra foi composta por de 41% de participantes do sexo feminino, com idade média de 21,10 (DP = 4,49), e 75,6% em instituições de ensino superior. Os resultados da análise fatorial confi rmatória forneceram apoio para o modelo unidimensional original do GAD-7 no contexto brasileiro. As análises de variância (ANOVA) mostraram que os escores do GAD-7 foram signifi cativamente diferentes entre homens e mulheres, com as mulheres apresentando maiores escores que os homens. A escala demonstrou uma boa fi dedignidade; sendo que tanto o coefi ciente de Cronbach alfa (α = 0,916) e rho coefi ciente de confi abilidade composta (ρ = 0,909) foram adequados. A análise dos parâmetros dos itens mostrou itens 5 e 7 apresentaram os limiares mais elevados de severidade para o traço-latente de ansiedade generalizada, enquanto que o item 1 apresentou as menores. Nossos resultados sugerem que a versão Português Brasileiro do GAD-7 é adequada para avaliar os sintomas do transtorno de ansiedade generalizada em adultos brasileiros em ambientes comunitários.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
