Parental incarceration has a major impact on children and families. The influx of incarcerated parents, as well as the high-risk nature of parental incarceration, has resulted in an elevated need for proper parent-focused prison programs. However, while parenting programs are often viewed as an effective method to improve the negative consequences of incarceration, there are conflicting findings on parenting programs' impact and effectiveness. Additionally, there is little connection between parenting programs and recidivism (Purvis, 2013). Using data from the Multi-Site Family Study on Incarceration, Parenting and Partnering (Bir & Lindquist, 2022), this study aims to examine the extent to which attending parenting programs while incarcerated contributes to the parent-child relationship, parental warmth, and recidivism. Using propensity score matching, mean comparison tests, linear regression, and logistic regression, analyses focused on how parenting program attendance influenced said variables both while still incarcerated and during reentry. Findings generally did not support the position that attending parenting programs while incarcerated is associated with stronger parent-child relationship quality, parental warmth, and a lower risk of recidivism. Significance and limitations, as well as policy implications and directions for future research, are discussed.
