Se han comparado asimismo las puntuaciones del BAI con las de otros marcadores de la ansiedad empleados en Portugal. En lo que respecta a la validez convergente, correlaciona significativamente con todas las medidas de ansiedad utilizadas y con la medida de la sensibilidad a la ansiedad. The study of anxiety-related factors has shown that there are a large number of variables that affect its origin, development, maintenance and alteration.
However, appropriate instruments are needed for credible research. Therefore, the validation of one of the most widely used anxiety scale at the international level is of paramount importance. BAI has been analyzed with the rating scale model to evaluate their psychometric quality, for which we have tested the response categories and estimated the parameters of the model, its precision, the degree of data-model fit, the unidimensionality and the absence of differential item functioning.
We compared BAI scores with those of other evaluation instruments of anxiety used in Portugal. The sample consists of adults of both genders men and women aged years mean age We used a demographic questionnaire designed for this research, with questions about gender, age, place of residence, ethnicity, educational level, religion, marital status, number of children and occupation.
The results also show that the subjects anxiety level is very low and that most people are below the range of the variable in which the items are located, indicating that it is not designed to measure with high precision people with low levels of anxiety. The analyses also indicate that the measure can be treated as unidimensional. In terms of impact, male participants and those older than 30 obtained lower BAI scores, which corroborates the literature on the matter.
With respect to convergent validity, BAI correlates significantly with all the anxiety measures and with anxiety sensitivity. The remaining scales showed similar results to the BAI, but it is BAI the one with the lowest item misfit and percentage of very misfit persons, as well as the most suited to one-dimensional structure, together with the ASI.
We conclude that BAI provides measures of good psychometric quality, as good or even better, in some cases, than the rest of the anxiety scales used for the Portuguese population.
