Prospective Associations Between Pornography Viewing and Sexual Aggression Among Adolescents.

Adolescence is a critical period for sexuality development; this study examined prospective associations between pornography use and sexual aggression using a longitudinal study of middle and high school students surveyed five times across 3 years (mean age = 13.7 years at baseline; 53.2% female; 76.5% White; 21.0% Native American; 88.9% heterosexual). Across waves, 15.7%-29.0% of adolescents had viewed pornography in the past 6 months. Results indicated significant, reciprocal associations between pornography and sexual harassment perpetration that were stronger for male adolescents, and some significant associations between pornography use and subsequent sexual assault perpetration. Findings underscore the need to consider multiple theories of the link between pornography viewing and aggression and need for media literacy sexual education beginning in middle school.
