Alcohol use and sexual behavior are important risk behaviors in adolescent development, and combining the two is common. The reasoned action approach (RAA) is used to predict adolescents' intention to combine alcohol use and sexual behavior based on exposure to alcohol and sex combinations in popular entertainment media. We conducted a content analysis of mainstream (n = 29) and Black-oriented movies (n = 34) from 2014 and 2013-2014, respectively, and 56 television shows (2014-2015 season). Content analysis ratings featuring character portrayals of both alcohol and sex within the same five-minute segment were used to create exposure measures that were linked to online survey data collected from 1,990 adolescents ages 14 to 17 years old (50.3% Black, 49.7% White; 48.1% female). Structural equation modeling (SEM) and group analysis by race were used to test whether attitudes, norms, and perceived behavioral control mediated the effects of media exposure on intention to combine alcohol and sex. Results suggest that for both White and Black adolescents, exposure to media portrayals of alcohol and sex combinations is positively associated with adolescents' attitudes and norms. These relationships were stronger among White adolescents. Intention was predicted by attitude, norms, and control, but only the attitude-intention relationship was different by race group (stronger for Whites).
饮酒和性行为是青少年发展过程中的重要风险行为，两者结合的情况也很常见。基于对青少年在流行娱乐媒体中接触到的酒精和性行为组合的观察，理性行为方法（RAA）被用于预测青少年将饮酒和性行为结合的意图。我们对 2014 年和 2013-2014 年分别主流（n=29）和黑人定向电影（n=34）以及 56 部电视剧（2014-2015 季）进行了内容分析。内容分析评级以同一五分钟片段内的角色对酒精和性的描绘为特色，用于创建暴露度测量值，这些测量值与从 1990 名 14 至 17 岁青少年（50.3%为黑人，49.7%为白人；48.1%为女性）在线调查数据相关联。结构方程模型（SEM）和按种族进行的分组分析用于检验媒体暴露对结合饮酒和性行为意图的影响是否通过态度、规范和感知行为控制来调节。结果表明，对于白人和黑人青少年来说，接触媒体对酒精和性行为组合的描述与青少年的态度和规范呈正相关。这种关系在白人青少年中更为强烈。意图由态度、规范和控制来预测，但只有态度-意图关系因种族群体而异（对白人更强）。
