(1) Question-behavior effect. The study’s results suggest that asking adolescents about their pornography use did not increase their interest in or use of such material.

(2) Pornography and content progression. The study found no empirical support for the content progression thesis (the longer the pornography use, the more extreme content consumed). The present study was the first longitudinal study to explore this concept.

(3) Pornography use and psychological well-being. The study, which was motivated by rising concerns about the impact of pornography use on young people’s well-being, did not support the notion that pornography use is associated with reduced well-being in the period between middle and late adolescence, regardless of gender.

(4) Pornography use and sexual risk taking. Results of multiple longitudinal explorations of relationships between pornography use and sexual risk taking suggest that: (a) Pornography use was unrelated to the timing of male adolescents’ sexual debut (findings among female adolescents were inconclusive); and (b) controlling for potential confounders, associations between pornography use and basic indicators of sexual risk taking (i.e., condom use and multiple sexual partnerships) were non-significant. However, when a more inclusive, cumulative index of sexual risk taking was employed, we found a significant link between the frequency of pornography use and sexual risks at the age of 17 in both genders.

(5) Pornography and male sexual aggressiveness. Results suggest no significant association in the subsequent growth in pornography use and self-reported sexual aggressiveness in male adolescents. It should be noted that participants who reported little or no sexual aggressiveness watched pornography less often at the age of 16 than their peers who reported substantial sexual aggressiveness.

(6) Problematic pornography use. This study’s findings suggest that some male adolescents exhibit symptoms of problematic pornography use, broadly defined as out-of-control use. The finding highlights a need for counseling services for young people who have difficulties in controlling their pornography use—even when faced with negative consequences.

(7) Pornography use and sexual satisfaction. The study aimed to address the conflicted findings among cross-sectional studies. According to the results, changes in pornography use were not related to adolescent sexual satisfaction in either female or male participants.

(8) The role of parents. We found evidence that parental monitoring was negatively related to the frequency of pornography use at the age of 16, regardless of gender (i.e., higher levels of parental engagement correspond to lower pornography use). After the age of 16, higher parental monitoring was associated with lower frequency of pornography use only among female adolescents.
