Using a longitudinal web-based survey of adolescents 14-16 years of age, we estimate regression models where self-reported sexual behavior and content analytic-based exposure to sex in the media are related cross-sectionally and longitudinally. We find evidence for both cross-sectional non-recursive and prospective longitudinal relationships even after adjusting for both established predictors of sexual behavior (e.g., physical development, having a romantic partner, parental monitoring, peer and parental norms, respondent's age) and of exposure to sexual media content (e.g., time the respondent goes to bed, extracurricular activities, television in the bedroom, total time spent with television, music, videogames, and magazines). Sexually active adolescents are more likely to expose themselves to sex in the media and those exposed to sex in the media are more likely to progress in their sexual activity. These findings are consistent with others in the literature that demonstrate a causal effect of exposure to sexual content on sexual behavior but extend established results by also looking at the causal effect of sexual behavior on exposure both cross-sectionally and over time.
通过对14至16岁青少年进行基于网络的纵向调查,我们估计了回归模型,其中自我报告的性行为与基于内容分析的媒体性接触在横断面和纵向上存在关联。即使在对性行为的既定预测因素(例如身体发育、有恋爱伴侣、父母监督、同伴和父母规范、受访者年龄)以及性媒体内容接触(例如受访者上床睡觉时间、课外活动、卧室里的电视、花在电视、音乐、电子游戏和杂志上的总时间)进行调整之后,我们仍发现了横断面非递归关系和前瞻性纵向关系的证据。性活跃的青少年更有可能接触媒体中的性内容,而接触媒体中性内容的青少年更有可能在性行为上有所进展。这些发现与文献中的其他研究结果一致,这些研究表明接触性内容对性行为有因果影响,但通过同时考察性行为在横断面和随时间推移对接触的因果影响,扩展了已有的研究结果。
