Longitudinal Relations Between Heterosexual Adolescents’ Perceived Exposure to Sex-Positive Television Messages and Their Supportive Attitudes and Behaviors Toward the LGBTQ+ Community

The literature on heterosexual adolescents’ television viewing and its over-time impact on attitudes and behaviors regarding LGBTQ+ is limited. The current study aims to fill this gap in the literature by using three-wave data from 338 heterosexual adolescents ( Mage = 15.29, SD = 1.48, 68.6% girls). We explored relations between adolescents’ perceived exposure to sex-positive television messages, their respectful approach to different sexual expressions, and their endorsement of supportive behavior regarding LGBTQ+. A Random Intercept Cross-Lagged Panel Model (RI-CLPM) showed that, at a between-person level, perceived exposure to sex-positive television messages was related to the endorsement of supportive behavior regarding LGBTQ+. Yet, results revealed that an increased perceived exposure to sex-positive television messages was not associated with respectful approach to different sexual expressions and endorsement of supportive behavior regarding LGBTQ+ at the individual level. No sex or traditional gender role orientation differences were found. Our findings hopefully encourage sexual media research to further distinguish between-and within-person relations and to consider potential testing effects that mask true within-person change.
