Data from a Swedish PISA-sample were used (1) to identify a digital reading factor, (2) toinvestigate gender differences in this factor (if found), and (3) to explore how computergame playing might relate to digital reading performance and gender. The analyses wereconducted with structural equation modeling techniques. In addition to an overall readingfactor, the hypothesized digital reading factor was identified. When the overall readingperformance was taken into account, a relative difference in favor of the boys fordigital reading was indicated. This effect was mediated by a game-playing factorcomprising the amount of time spent on playing computer games. Thus, the boys’better performance in digital reading was explained by the computer game-playing factor.
