Testing the content progression thesis: A longitudinal assessment of pornography use and preference for coercive and...

Content progression thesis (CPT), a direct application of conditioning theories to conceptualizing exposure to pornography, proposes that pornography use leads to viewing increasingly more extreme material due to the effect of satiation. To test this assumption, association between the frequency of pornography use and the preference for violent and coercive content were examined over a 24-month period using an online panel sample of male adolescents. Participants were 248 high school students who took part in at least three of five waves of the PROBIOPS study. The average baseline age was 16.1. Dual-domain latent growth curve modeling was used to test the CPT. The preference for violent/coercive pornography was found to decrease over time. Moreover, its dynamics was unrelated to latent growth in pornography use. In this first longitudinal assessment, the CPT was not found to be a useful model for understanding the patterns and potential consequences of adolescent pornography use.
