The aim of the present study is to determine the relationship between Child Access Prevention (CAP) laws and state-level youth firearm suicide rates. This paper differs from prior research in several ways. First, this is one of the few studies to focus exclusively on youth firearm suicide rates. Second, this study uses one of the largest and most recent data sets of any study on this topic. Third, this study uses the synthetic control method, an empirical technique that has not been previously used to study this topic. Results are mixed. For nine states, introduction of CAP laws resulted in lower youth firearm suicide rates. In thirteen states, however, CAP laws had no significant effects on youth firearm suicide rates. Hence, CAP laws did not have statistically significant effects on youth firearm suicide rates for most of the states examined. Given these inconclusive results, more research is warranted in this area.

本研究的目的是确定预防儿童进入（CAP）法律与州级青少年枪支自杀率之间的关系。本文在一些方面与先前的研究有所不同。首先，这是专门针对青少年枪支自杀率的少数研究之一。其次，本研究使用了有关此主题的任何研究中规模最大，最新的数据集之一。第三，本研究使用综合控制方法，这是一种以前没有用于研究该主题的经验技术。结果好坏参半。对于9个州，CAP法的出台导致青少年枪支自杀率降低。但是，在13个州中，CAP法对青少年枪支自杀率没有重大影响。因此，在大多数接受调查的州中，CAP法对青少年枪支自杀率没有统计学上的显着影响。
