National Inmate Survey (NIS) - Jails: Full Survey Respondents, [United States], 2007-2009

The National Inmate Survey (NIS) is part of the Bureau of Justice Statistics' (BJS) National Prison Rape Statistics Program, which gathers mandated data on the incidence and prevalence of sexual assault in correctional facilities under the Prison Rape Elimination Act of 2003 (PREA; P.L. 108- 79). Inmates are randomly assigned to receive either a survey of sexual victimization or a survey of mental and physical health, past drug and alcohol use, and treatment for substance abuse. About 92 percent of the respondents completed modules through the survey of sexual victimization while the other eight percent completed modules through the alternative survey. However, the data in this study focuses solely upon substance use and treatment. No respondent answered questions about sexual victimization.

The same eight percent of respondents (n=6,577) who completed the alternative survey are the same 6,577 respondents from the study National Inmate Survey (NIS) - Jails: Alternative Survey Respondents Only, [United States], 2007-2009 (ICPSR 37010).
