“…However, empirical investigations of these programs have by and large found little or no reductions in recidivism when comparing program participants with their control or comparison group counterparts (Frederick & Roy, 2003;Wiebush, Wagner, McNulty, & Wang, 2005). Other longitudinal studies have discovered that participation in community-based reentry services such as mental health and mentoring may reduce recidivism (Bullis & Yovanoff, 2002;Aftercare for Indiana Through Mentoring, 2004), but that these effects diminish over time (Bouffard & Bergseth, 2008;Drake & Barnoski, 2006). Given this evidence of fading effects, it is surprising that very few published studies have examined the independent influence of service dosage, or length of participation in a reentry intervention, on recidivism outcomes.…”
