The present study investigated the relationship between different types of sexual media use (i.e., sexually explicit internet material, sexually oriented reality TV, and sexy self-presentations on social network sites) and adolescents' willingness to engage in casual sex, as well as underlying sociocognitive processes of this relationship. Drawing on a longitudinal three-wave panel study among 1,467 adolescents (aged 13–17, 50% female), we found that exposure to sexually explicit Internet material directly predicted adolescents' willingness to engage in casual sex. Exposure to sexy self-presentations of others on social network sites and sexually oriented reality TV predicted adolescents' willingness to engage in casual sex indirectly through descriptive peer norms on casual sex.

青少年的性媒体使用和从事随意性行为的意愿：微分关系和潜在过程

本研究调查了不同类型的性媒体使用方式（即露骨的性爱互联网材料，性取向的现实电视以及社交网站上的性感自我表现）与青少年从事随意性行为以及潜在的性行为之间的关系。这种关系的社会认知过程。根据对1,467名青少年（13-17岁，女性占50％）的纵向三波面板研究，我们发现暴露于色情露骨的互联网材料直接预测了青少年进行休闲性行为的意愿。在社交网站和性取向电视上露面的他人的性感自我表现预示着青少年愿意通过描述性同伴规范来间接参与休闲性行为。
