The purpose of this study is to estimate the association between adolescent sexual behavior and exposure to sexual media content. A three-wave, longitudinal survey sample (N = 506) of 14- to 16-year-olds at baseline is analyzed using growth curves. Growth trajectories are linear for sexual behavior but not for exposure to sexual media content. The signs of the exposure slopes are not uniformly positive: Hispanic and African American respondents show declines of exposure to sexual media content over the age range investigated here. Although changes in exposure to sex content are highly associated with changes in sexual behavior among Whites, there is little or no association between changes in these variables among Blacks.
本研究旨在估计青少年性行为与接触性媒体内容之间的关联。使用增长曲线分析了基线时 14 至 16 岁的三波纵向调查样本(N=506)。性行为的增长轨迹是线性的,但性媒体内容的暴露轨迹不是。暴露斜率的符号并非完全为正:西班牙裔和非裔美国受访者在研究范围内的年龄范围内,性媒体内容的接触呈下降趋势。尽管白人中,性内容接触的变化与性行为的变化高度相关,但黑人中这些变量之间的关联很小或没有。
