Parental involvement (PI) laws require that physicians notify or obtain consent from a parent(s) of a minor seeking an abortion before performing the procedure. Several studies suggest that PI laws curb risky sexual behavior because teens realize that they would be compelled to discuss a subsequent pregnancy with a parent. We show that prior evidence based on gonorrhea rates overlooked the frequent under-reporting of gonorrhea by race and ethnicity, and present new evidence on the effects of PI laws using more current data on the prevalence of gonorrhea and data that are novel to this literature (i.e., chlamydia rates and data disaggregated by year of age). We improve the credibility of our estimates over those in the existing literature using an event-study design in addition to standard difference-in-difference-in-differences (DDD) models. Our findings consistently suggest no association between PI laws and rates of sexually transmitted infections or measures of sexual behavior.
父母参与（PI）法律要求医生在为寻求堕胎的未成年人实施手术前通知或获得其父母的同意。有几项研究表明，PI 法律可以遏制危险的性行为，因为青少年意识到他们将被迫与父母讨论随后的怀孕问题。我们表明，先前基于淋病发病率的证据忽略了种族和民族经常漏报淋病的情况，并利用淋病流行率的最新数据以及该文献中新颖的数据（即衣原体发病率和按年龄细分的数据）提供了关于 PI 法律影响的新证据。我们使用事件研究设计以及标准的双重差分法（DDD）模型，提高了我们的估计在现有文献中的可信度。我们的研究结果一致表明，PI 法律与性传播感染率或性行为措施之间没有关联。
