Este trabalho objetivou avaliar as propriedades psicométricas da escala Generalized Anxiety Disorder (GAD-7) em uma amostra não-clínica brasileira. Para tanto, foi realizada Análise Fatorial Confirmatória e de invariância de medida, assim como investigada evidências de fidedignidade e de validade baseada na relação com outras variáveis. Além disso, rastreou-se os níveis de ansiedade no contexto da pandemia da COVID-19 e verificou-se a relação com o sexo e a escolaridade da amostra. Participaram 4805 pessoas, de ambos os sexos e de todas as regiões do país e aproximadamente 30 anos de idade, em média. Os resultados evidenciaram unidimensionalidade da GAD-7 e sua invariância de medida entre indivíduos com diferentes níveis de escolaridade e sexo. Os participantes apresentaram, em sua maioria, nível moderado e severo de ansiedade. Observou-se que o sexo feminino e menor nível de escolaridade aumentaram as chances de apresentar sintomatologia ansiosa significativa.
