The purpose of the National Inmate Survey (NIS) is to gather data on inmates experiences within the state and federal judicial system. It is part of the Bureau of Justice Statistics Prison Rape Statistics Program (PREA). The primary data gathered as part of this program is on the prevalence of sexual assault and rape in correctional facilities. The Prison Rape Elimination Act of 2003 (PREA; P.L. 108-79) requires a 10 percent sample of correctional facilities to be listed by incidence of sexual assault, with a minimum of one prison and one jail facility in each state. A secondary purpose is to report on substance use, alcohol use, and substance abuse treatment prior to and during incarceration. The data in this particular study focuses solely on these secondary purposes. The data file does not contain data on sexual assault and rape during the respondent's stay in jail.美国全国囚犯调查（National Inmate Survey, NIS）旨在收集囚犯在州级与联邦司法体系内的经历相关数据。该调查隶属于美国司法统计局监狱强奸统计项目（Prison Rape Statistics Program, PREA）。本项目的核心采集数据为惩教设施内性侵犯与强奸案件的发生率。2003年《监狱强奸消除法案》（Prison Rape Elimination Act of 2003, PREA; P.L. 108-79）要求按照性侵犯案件发生率选取10%比例的惩教设施作为样本，且每个州需至少包含1所监狱与1所看守所。本项目的次要目标为统计并报告囚犯入狱前及监禁期间的物质使用、酒精摄入与药物滥用治疗情况。本项特定研究的数据仅聚焦于上述次要目标。本次所用数据文件未包含受访者在看守所羁押期间遭受性侵犯与强奸的相关数据。
