The adaptation of psychological instruments is a complex process that requires a high methodological rigor. Because there is no consensus in the literature about its steps, this article discuss some essential aspects regarding the cross-cultural adaptation of psychological instruments and proposes guidelines to the researchers about the different steps of this process. Some considerations regarding the validation of the adapted instrument are also presented. In this stage, we discuss some aspects regarding the factorial structure of the instrument, which might be evaluated through statistical procedures, such as exploratory and confirmatory factor analysis. More than that, the authors provide some guidelines to the validation of psychological instruments in different cultures.
