Many parents fail to interact with their children regularly about media content and past research has identified few predictors of parents' engagement in parental mediation behaviors. This correlational study explored the relationship between parents' critical thinking about media and parents' provision of both active and restrictive mediation of television content. Results revealed that parents' critical thinking about media is positively associated with both active and restrictive mediation, relationships mediated by parents' attitudes toward parent-child interactions about media. These findings suggest that media literacy programs aimed at improving parents' critical thinking about media may be an effective way to alter children's responses to media exposure and that these media literacy programs should promote positive attitudes toward parental mediation.
