English abstract Our objective was to conduct a validation study of the Portuguese version of the Beck Anxiety Inventory (BAI) by means of the Rasch Rating Scale Model, and then compare it with the most used scales of anxiety in Portugal. The sample consisted of 1,160 adults (427 men and 733 women), aged 18-82 years old (M=33.39; SD=11.85). Instruments were Beck Anxiety Inventory, State-Trait Anxiety Inventory and Zung Self-Rating Anxiety Scale. It was found that Beck Anxiety Inventory's system of four categories, the data-model fit, and people reliability were adequate. The measure can be considered as unidimensional. Gender and age-related differences were not a threat to the validity. BAI correlated significantly with other anxiety measures. In conclusion, BAI shows good psychometric quality
Portuguese abstract Foi objetivo a validação da versão portuguesa do Beck Anxiety Inventory (BAI) mediante o modelo Rasch Rating Scale e a sua comparação com as escalas mais usadas de ansiedade em Portugal. A amostra consistia de 1160 adultos (427 homens e 733 mulheres) com idades entre 18-82 anos (M = 33,39; DP = 11,85). Os instrumentos utilizados foram: BAI, State-Trait Anxiety Inventory e Zung Anxiety Scale. Verificou-se que o sistema de quatro categorias, o ajuste dos dados ao modelo e a fidelidade das pessoas eram adequados. A medida é unidimensional. O género e as diferenças relacionadas com a idade não se mostraram ameaças à validade. O BAI correlaciona-se significativamente com as restantes medidas de ansiedade. Conclui-se que o instrumento apresenta boa qualidade psicométrica
