New report details redesign and pretest of BJS inmate survey

BJS-funded third-party report released: Survey of Inmates in Local Jails (SILJ) Redesign and Pretest. The report presents Abt Global’s and BJS’s review of and recommended revisions to the existing SILJ instrument. The redesign project was divided into three phases: 1) the design of the survey instrument, 2) the pretest phase, and 3) the final report and recommendations, which support the national implementation of the redesigned SILJ. 

The SILJ is the only nationally representative survey that collects self-reported, individual-level information on hard-to-reach jail populations, making it a vital resource for policymakers, facilities, government agencies, and researchers. Since the survey was last administered in 2002, the characteristics of jail populations have changed, and new policies and policing reforms have been enacted. Abt Global and BJS entered into a cooperative agreement in 2015 to address gaps in the 2002 version of the instrument with the goal of producing reliable national estimates of local jail populations through the redesigned survey instrument.
