Abstract：
Half of the offenders convicted of impaired driving in the United States are sentenced to install alcohol ignition interlock devices (IIDs), which prevent them from starting their vehicles if they have been drinking. No research has yet explored offenders\' patterns of alcohol consumption and driving under the influence of alcohol (DUI) from the time before the arrest to the time period after the IID is installed. This study aims to fill that gap in knowledge.
Using the Timeline Follow-back interview procedure, we assessed the daily drinking of 153 convicted DUI offenders\' self-reported total alcohol consumption and rates of self-reported driving after drinking over 4 phases: before DUI arrest, between arrest and IID installation, during the phase on the interlock, and after the interlock is removed. Because information about behaviors in each period was not available for every participant, comparisons were made using paired-sample contrasts.
Compared with before the arrest, total alcohol use decreased by 50% in the 4-month phase following arrest and before IID installation, though it did not change much afterward. The frequency of drinking and driving decreased sharply after the arrest (-82%), with further decrease upon installation of the interlock (-58%, p = 0.05). The frequency of drinking and driving after the IID was removed returned to preinstallation drinking and driving status (+58%, p = 0.01).
Participants made significant adjustments to their drinking behavior by adhering to the traditional DUI driving restrictions in the postarrest phase. Although installation of an IID was not associated with a significant change in drinking, it further reduced the frequency of drinking and driving. Evaluations of the IID experience should take into account information on an individual\'s drinking and DUI behaviors not only before the IID was installed, but before the individual was arrested.

摘要：
在美国，一半因驾驶受损而被定罪的罪犯被判处安装酒精点火联锁装置(IID)，如果他们一直在喝酒，这会阻止他们启动车辆。尚未有研究探索从逮捕前到安装IID后的时间段，在酒精（DUI）的影响下饮酒和驾驶的违法者模式。这项研究旨在填补这一知识空白。
使用时间轴跟进访谈程序，我们评估了153名被定罪的DUI罪犯的每日饮酒量，以及饮酒后四个阶段的自述总饮酒量和自述驾驶率：DUI被捕前，在逮捕和IID安装之间，在联锁阶段，在互锁被移除之后。因为不是每个参与者都能获得每个时期的行为信息，使用配对样本对比进行比较.
与被捕前相比,在逮捕后和安装IID之前的4个月阶段，总酒精使用量下降了50%，尽管后来没有太大变化。被捕后酒后驾驶频率急剧下降(-82%),随着联锁装置安装后的进一步减少(-58%，p=0.05)。IID移除后的饮酒和驾驶频率恢复到安装前的饮酒和驾驶状态(+58%,p=0.01)。
参与者在最后阶段坚持传统的DUI驾驶限制，对饮酒行为进行了重大调整。尽管IID的安装与饮酒的重大变化无关，它进一步减少了饮酒和驾驶的频率。对IID体验的评估不仅应在安装IID之前，还应考虑有关个人饮酒和DUI行为的信息，但在个人被捕之前。
