Two-thirds of sexually experienced teenagers in the United States say they wish they had waited longer to have intercourse for the first time. Little is known about why such a large proportion of teenagers express disappointment about the timing of their initial experience with sex.
Data on television viewing, on regret about the timing of first intercourse and on potentially relevant covariates were obtained from a national, three-year (2001-2004) longitudinal survey of adolescents aged 12-17 at baseline. Logistic regression and path analysis were used to examine the association between exposure to sex on television and the likelihood of regret following sexual initiation, the extent to which shifts in expectations about the positive consequences of sex mediate this association and whether these relationships differ by gender.
Sixty-one percent of females and 39% of males who had sex for the first time during the study period reported that they wished they had waited to have sex. Exposure to sexual content on television was positively associated with the likelihood of regret following sexual initiation among males (coefficient, 0.34) but not females. The association among males was partly explained by a downward shift in males' sex-related outcome expectancies following sexual initiation.
Interventions that limit teenagers' exposure to televised sexual content, that provide a more accurate portrayal of sexuality than typically depicted on television or that help adolescents think critically about televised sexual content may help teenagers make more carefully considered decisions about sexual debut.
在美国,有过性经历的青少年中有三分之二表示,他们希望自己能更晚一些才首次发生性行为。对于为何有如此大比例的青少年对自己首次性经历的时机感到失望,人们知之甚少。
从一项针对12至17岁青少年的全国性、为期三年(2001 - 2004年)的纵向调查中获取了关于电视观看情况、对首次性行为时机的后悔程度以及潜在相关协变量的数据,该调查以这些青少年在基线时的情况为起始。使用逻辑回归和路径分析来检验接触电视上的性内容与首次性行为后后悔可能性之间的关联、对性行为积极后果期望的变化在多大程度上介导了这种关联,以及这些关系在性别上是否存在差异。
在研究期间首次发生性行为的女性中有61%,男性中有39%表示他们希望自己当初能等待再发生性行为。接触电视上的性内容与男性首次性行为后后悔的可能性呈正相关(系数为0.34),但与女性无关。男性中的这种关联部分可由首次性行为后男性与性相关的结果期望的下降来解释。
限制青少年接触电视上性内容的干预措施、提供比电视上通常描绘的更准确的性观念描述的干预措施,或者帮助青少年批判性思考电视上性内容的干预措施,可能有助于青少年对首次性行为做出更审慎的决定。
