This study examines the effects of informational, interactional, and creative forms of Internet use on behavioral and cognitive indicators of youth democratic engagement. Data from an extensive two-wave panel survey of Swedish adolescents (N = 1,520) were examined. Results show that the effects of informational and interactional Internet use on political participation are indirect, with online political interactions acting as an intervening variable. In addition, creative production was found to be a direct positive predictor of online and offline political participation but negatively related to political knowledge. The effects were statistically significant even when accounting for self-selection and previous levels of democratic engagement. Taken together, these findings contribute novel theoretical insights into the mechanisms by which Internet use may encourage or hinder youths’ democratic engagement.
