Statewide Implementation of Parenting with Love and Limits among Youth with Co-Existing Internalizing and Externalizing Functional Impairments Reduces Return to Service Rates and Treatment Cost. Adm Policy Ment Health (2017). doi:10.1007/s10488-016-0788-4

In this QE study, the implementation of PLL with the State of Idaho Community Mental Health service was examined with the program intent of increasing efficiency of services to youth with co-existing internalizing and externalizing functional impairments.  This study found that the treatment group experienced shorter tratment durations and returned to CMH services at significantly lower rates than the treatment-as-usual group.  The treatment group also demonstrated significant decreases in internalizing and externalizing symptoms over time.

This quasi-experimental study looked to evaluate the impact of a manualized reentry intervention with youth and their families beginning while the youth were incarcerated and continued through transition and into aftercare. This study examined recidivism outcomes for youth receiving services compared with a matched comparison sample, and showed improved outcomes for the PLL treatment group.

In this study, the PLL treatment group had significantly lower rates of recidivism than the comparison group. The PLL treatment group also reported statistically significant improvements in youth behavior. Lengths of service were also significantly shorter for the treatment sample than the matched comparison group. This study was conducted in Champaign County, Illinois and included a population of 70% whose race was identified as black.
