Despite increasing interest in the implications of adolescents' use of sexually explicit Internet material (SEIM), we still know little about the relationship between SEIM use and adolescents' casual sexual activities. Based on a three-wave online panel survey study among Dutch adolescents (N = 1079; 53.1% boys; 93.5% with an exclusively heterosexual orientation; M = 15.11; SD = 1.39), we found that watching SEIM predicted engagement in casual sex over time. In turn, casual sexual activities partially predicted adolescents' use of SEIM. A two-step mediation model was tested to explain the relationship between watching SEIM and casual sex. It was partially confirmed. First, watching SEIM predicted adolescents' perceptions of SEIM as a relevant information source from Wave 2 to Wave 3, but not from Wave 1 to Wave 2. Next, such perceived utility of SEIM was positively related to stronger instrumental attitudes toward sex and thus their views about sex as a core instrument for sexual gratification. Lastly, adolescents' instrumental attitudes toward sex predicted adolescents' engagement in casual sex activities consistently across waves. Partial support emerged for a reciprocal relationship between watching SEIM and perceived utility. We did not find a reverse relationship between casual sex activities and instrumental attitudes toward sex. No significant gender differences emerged.
尽管人们对青少年使用色情网络材料（SEIM）的影响越来越感兴趣，但我们仍然不太了解 SEIM 使用与青少年偶然性行为之间的关系。基于一项针对荷兰青少年的三波在线小组调查研究（N=1079；53.1%的男孩；93.5%具有异性恋取向；M=15.11；SD=1.39），我们发现观看 SEIM 可以预测青少年在一段时间内的偶然性行为。反过来，偶然的性活动部分预测了青少年对 SEIM 的使用。我们测试了一个两步中介模型来解释观看 SEIM 和偶然性行为之间的关系。该模型得到了部分验证。首先，观看 SEIM 预测了青少年从第 2 波到第 3 波对 SEIM 的感知，作为一个相关信息来源，但不能从第 1 波到第 2 波预测。接下来，这种对 SEIM 的感知效用与对性的更强工具性态度有关，从而影响他们对性的看法，即性是性满足的核心工具。最后，青少年对性的工具性态度一致地预测了青少年参与偶然性行为。观看 SEIM 和感知效用之间存在部分互惠关系的支持。我们没有发现偶然性行为和对性的工具性态度之间的反向关系。没有发现显著的性别差异。
