Prior work on the process of reentry from prison has highlighted the pivotal role that family and peers play during reintegration. Families are traditionally understood as important protective mechanisms against recidivism whereas peers are typically viewed as primarily criminogenic. Yet, drawing from differential coercion and social support theory, family and peer relationships can both be supportive (and protect against recidivism) and coercive (and contribute to recidivism). Using four waves of data from the Serious and Violent Offender Reentry Initiative, results of mixed-effects models demonstrate that family, but not peer, coercion relates to increased odds of reincarceration. Peer, but not family, social support relates to decreased odds of reincarceration. Findings suggest families are primarily criminogenic, whereas peers are protective during reentry.
