National Inmate Survey (NIS) - Prisons: Full Survey Respondents, [United States], 2008-2009
Add to My BasketDescription
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 94 percent of the respondents completed modules through the survey of sexual victimization while the other six 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 27,191 respondents who are in this data are also part of the 46,595 respondents from the study National Inmate Survey (NIS) - Prisons: Full Survey Respondents, [United States], 2007-2009 (ICPSR 37017).
Detailed Methodology
Between October 2008 and December 2009, 167 state and federal prisons were randomly selected across the nation to participate in the NIS-1. Of these 167 total facilities there were 116 state male facilities, 32 state female facilities, 16 federal male facilities, and 3 federal female facilities. A total of 46,19 inmates were selected during data collection. A total of 32,029 inmates ended up participating in the survey. Of that total, 27,191 completed the drug, alcohol, and treatment modules. About 94 percent of the respondents completed the modules through the sexual victimization survey while the other 6 percent completed the same modules through the alternative survey.
