Study Dates: 2009 Study Description: The purpose of this article is to describe the use of JCFP throughout the state of Utah and to reveal the effects of time in jail on recidivism. The results of the present study found that individuals served approximately 70% of time sentenced and that this trend was similar across offense types and most counties. Both the survival analyses and the linear regression model revealed that longer periods of time spent in jail for similar offenses did not reduce or increase the likelihood of recidivism. Additionally, the study did not find an “optimal time” for jail to reduce recidivism. The study also found that the largest effect on recidivism was risk level of offenders, which highlights the need for assessment and provision of appropriate services to address offender needs in order to reduce reoffense.
