We examined the role of parental media mediation in the relationship between media violence and adolescents' ADHD-related behaviors. Survey data from 1,017 adolescents (10-14 years) show that parents can play an important role in this relationship, depending on the media mediation strategies that they use (i.e., restrictive or active mediation) and how they apply these strategies (i.e., in a controlling, inconsistent, or autonomy-supportive way). Our findings support the notion that contextual factors are critical in understanding media effects, and provide directions for how parents can manage their adolescents' violent media use, and possibly by extension, their ADHD-related behaviors. Attention-deficit/hyperactivity disorder (ADHD) is one of the most common childhood behavioral disorders, characterized by inattention, hyperactivity, and impulsivity (American Psychiatric Association, 2013), with a prevalence of around five percent in Western societies (Polanczyk, de Lima, Horta, Biederman, & Rohde, 2007). Associated risks include peer rejection, academic failure, and substance abuse (Willoughby, 2003), thereby posing a serious challenge to children, parents, teachers, and health care professionals. Although ADHD is clinically defined as a categorical disorder, most scholars agree that its core symptoms represent an underlying continuous distribution
