Pregnancy Attitude Index-Adaptation for Brazilian Culture: The purpose of this study was to adapt the Pregnancy Attitude Index (PAI) for use in Brazilian culture.

As a result of the process, the instrument was shown to have a good degree of reliabity and internal consistency. It was also possible to group the response patterns of the women tested, and identify items of the instrument which need to be adjusted. It appears, however, that the PAI is suitable for use in Brazilian culture
