National Former Prisoner Survey, 2008

Under the Prison Rape Elimination Act of 2003, Congress mandated that the United States Department of Justice, Bureau of Justice Statistics (BJS) investigate former prisoners' experiences in prison to assist in understanding the incidence and prevalence of sexual victimization within the prison setting. BJS and its subcontractor, NORC at the University of Chicago, led a national data collection effort focusing on prison sexual assault as reported by former state prisoners. The focus of the National Former Prisoner Survey (NFPS) was sexual victimization among former state prisoners. The survey was divided into 6 sections. The first two sections were administered using a computer-assisted personal interviewing (CAPI) method and focused on demographic and criminal history information. The remaining sections, covering more sensitive information, were administered using a touch-screen-audio-assisted-computer-self-interviewing (TACASI) method. Sections A and B of the instrument collected demographic and criminal history information, as well as information on placements during the last continuous incarceration. Sections C and D captured detailed inmate-on-inmate sexual victimization during the last continuous incarceration, including the type of sexual activity, identification of facilities at which such incidents occurred, frequency of occurrences, and other specifics regarding sexual victimization. Section E addressed staff-on-inmate sexual victimization and misconduct, whether considered willing or unwilling, and gathered specifics of activity indicated. The last section, F, focused on the impacts of sexual assault on victimized respondents, as well as parole supervision characteristics for all respondents. The National Former Prisoner Survey (NFPS) began in January 2008 and concluded in October 2008, and involved the random selection of approximately 250 parole offices across the country using probability proportional-to-size (PPS) sampling procedures. Completed interviews were obtained for 17,738 respondents; supplemental data was collected on all former prisoners sampled in order to develop weights for national estimations.

根据《2003年监狱强奸消除法案》，美国国会授权美国司法部司法统计局（BJS）调查前囚犯的监狱经历，以助力理解监狱环境中性侵害的发生率与流行率。BJS及其分包商芝加哥大学全国民意研究中心（NORC）牵头开展了一项全国性数据收集工作，重点关注州立监狱前囚犯所报告的监狱性侵犯事件。全国前囚犯调查（NFPS）的核心是州立监狱前囚犯中的性侵害问题。该调查分为6个部分：前两部分采用计算机辅助个人访谈（CAPI）方法实施，重点收集人口统计学和犯罪史信息；其余涉及更敏感信息的部分则采用触摸屏音频辅助计算机自填访谈（TACASI）方法实施。问卷的A和B部分收集人口统计学、犯罪史信息及最后一次连续监禁期间的安置信息；C和D部分记录了最后一次连续监禁期间囚犯间性侵害的详细情况，包括性行为类型、事件发生的设施标识、发生频率及其他与性侵害相关的具体信息；E部分涉及狱警对囚犯的性侵害及不当行为（无论是否自愿），并收集了相关行为的具体细节；最后一部分F重点关注性侵犯对受害受访者的影响及所有受访者的假释监督特征。全国前囚犯调查（NFPS）于2008年1月启动，2008年10月结束，采用概率比例规模抽样（PPS）程序在全国范围内随机选取了约250个假释办公室，共完成17738名受访者的访谈；为制定全国估计权重，收集了所有抽样前囚犯的补充数据。
