Many policymakers, health professionals, and "safe sex" advocates respond to these troubling statistics by demanding more comprehensive sex education and broader access to contraceptives for minors. They assume that teens are unable to delay their sexual behavior and that a combination of information about and access to contraceptives will effectively lead to protected sex, preventing any form of harm to youngsters. Not only are these assumptions faulty, they tend to disregard important factors that have been linked to reduced teen sexual activity. A particularly noticeable omission is parental influence.
Parents, as teens themselves reveal, are the ones who have the most influence on their children's decisions about sex. Indeed, two-thirds of all teens share their parents' values on this topic.
When it comes to talking about teen sex, both teens and parents report high levels of communication. Parents, however, tend to perceive a greater level of communication than do teens. Nearly all parents (90 percent) report having had a helpful conversation about delaying sex and avoiding pregnancy with their teenage children, compared to 71 percent of teens who report having had such a conversation with their parents.[10] Many parents are also unaware of their teens' actual behavior. In a study of 700 teens in Philadelphia, 58 percent of the teens reported being sexually active, while only one-third of their mothers believed they were.[11]
The empirical evidence on the association between parental influences and adolescents' sexual behavior is strong. Parental factors that appear to offer strong protection against the onset of early sexual activity include an intact family structure; parents' disapproval of adolescent sex; teens' sense of belonging to and satisfaction with their families; parental monitoring; and, to a lesser extent, parent-child communication about teen sex and its consequences.
That parents play a role in teen sex points to at least two significant policy implications. First, programs and policies that seek to delay sexual activity or to prevent teen pregnancy or STDs should encourage and strengthen family structure and parental involvement. Doing so may increase these efforts' overall effectiveness. Conversely, programs and policies that implicitly or explicitly discourage parental involvement, such as dispensing contraceptives to adolescents without parental consent or notice, contradict the weight of social science evidence and may prove to be counterproductive and potentially harmful to teens.
Research Findings
A Research Note. Social scientists are primarily concerned with the question of causality. For example, does parental disapproval of teen sex independently cause teens to delay sexual activity? Causality, however, is difficult to establish in social science research. Using statistical methods and appropriate data sources, social scientists infer certain reasonable conclusions from their research. The degree of confidence with which they draw inferred conclusions depends largely on data quality, study design, and statistical method.
The research on parental influences and teen sexuality is extensive. A substantial portion of the research is based on cross-sectional data, which capture information at one point in time and provide a "snapshot" view. As such, they limit researchers' ability to draw stronger conclusions. At best, cross-sectional data offer evidence of correlations, e.g., parental disapproval of teen sex is associated with delayed sexual initiation. Longitudinal surveys, on the other hand, follow the same group of individuals over time, which allows researchers to infer stronger findings. This paper mostly highlights findings from studies that use longitudinal data, which offer more rigorous conclusions.
