Moving intelligence measurement online: adaptation and validation of the Polish version of the Pathfinder general cognitive ability test

Online measurement is on the rise in every subdiscipline of the broad social sciences. This trend may stem from the numerous advantages offered by this data collection mode, e.g. its cost-efficiency and ability to quickly collect large and diversified samples. However, online studies require measurement tools that have been adapted for online assessment in terms of their design, length, and attractiveness and are as valid and reliable as their traditional counterparts. These new needs in measuring cognitive abilities were recently addressed by the creation of Pathfinder, a novel online, gamified general cognitive ability measure. In this article, we aimed to offer further validation for Pathfinder by presenting the results of its first language adaptation. The results of our adaptation showed that the Polish version of Pathfinder is a reliable and valid measure suited for low stakes, computer-based, and online assessment, supporting the applicability of Pathfinder for different linguistic contexts.
