The interviews, which averaged 35 minutes in length, used computer-assisted personal interviewing (CAPI) and audio computer-assisted self-interviewing (ACASI) data collection methods. For approximately the first two minutes, survey interviewers conducted a personal interview using CAPI to obtain background information and date of admission to the facility. For the remainder of the interview, respondents interacted with a computer administered questionnaire using a touchscreen and synchronized audio instructions delivered via headphones. Respondents completed the ACASI portion of the interview in private, with the interviewer either leaving the room or moving away from the computer. A shorter paper questionnaire was made available for inmates who were unable to come to the private interviewing room or interact with the computer. The paper form was completed by 751 prison inmates (or 1.9 percent of all prison interviews)--733 were completed by adult prison inmates (1.9 percent of adult prison inmate interviews) and 18 were completed by prisoners ages 16 to 17 (3.4 percent of all prison inmate interviews of inmates ages 16 to 17). The paper questionnaire was also completed by 264 jail inmates (0.5 percent of all jail inmate interviews)--255 were completed by adults (0.5 percent of adult jail inmate interviews) and 9 were completed by jail inmates ages 16 to 17 (0.7 percent of jail inmate interviews of inmates ages 16 to 17). In addition, five paper questionnaires were completed by military inmates (0.9 percent of all military inmate interviews). Most of these inmates were housed in administrative or disciplinary segregation or were considered too violent to be interviewed Before the interview, inmates were informed verbally and in writing that participation was voluntary and that all information provided would be held in confidence. Interviews were conducted in either English (96 percent in prisons, 95 percent in jails, 35 percent in ICE facilities, and 100 percent in military and Indian country facilities) or Spanish (4 percent in prisons, 5 percent in jails, and 65 percent in ICE facilities).
