The peak years of offending in the general population and among those with serious mental health conditions (SMHC) are during emerging adulthood. completed the intervention. Study retention rates also were high. Pre-post analyses exposed significant reductions in participants’ MH symptoms justice-system involvement and associations with antisocial peers. Intro Adolescence and growing adulthood are the age periods of maximum offending in the general population1-3 as well as among individuals with severe mental health conditions (SMHC; 4). “Growing adulthood” will be used herein to refer to age groups 17-25 unless normally mentioned.5 Compounding this individuals with SMHC have greater justice system involvement than those without SMHC both as Caffeic Acid Phenethyl Ester juveniles6-8 and growing adults.6 9 10 For those with intensive adolescent mental health service use the Caffeic Acid Phenethyl Ester majority will be arrested by their mid-20’s.11-14 Further among emerging adults with SMHC those with recent justice system involvement are at very best risk for arrests. Indeed data show that among recently arrested growing adults with SMHC re-arrest rates peak at 50% for males and 39% for ladies.14 Justice system involvement can be a strong impediment to positive development. CRYAA It is a strong predictor of school dropout 15 16 Caffeic Acid Phenethyl Ester unemployment 17 low income 18 welfare dependence 17 and substance abuse problems17 21 in young adulthood. Therefore reducing recidivism with this high risk group with SMHC during the age groups when offending becomes criminal rather than delinquent might significantly improve adult trajectories of offending and support more positive developmental results.22 Yet there are no established interventions with evidence of efficacy to reduce recidivism among emerging adults with or without SMHC. There are evidence-based interventions to reduce offending and re-offending in juveniles Caffeic Acid Phenethyl Ester in the general populace including Multisystemic Therapy23 and Multidimensional Treatment Foster Care 24 but these solutions have not been used or evaluated with individuals more than 17 years of age.25 Evidence-based practices for reducing recidivism in the adult general population include substance abuse treatment 26 education27 or employment28 29 programs and the general array of cognitive behavioral approaches for reducing offending behavior.30 31 All have moderate effects on recidivism but the efficacy of these methods specifically with emerging adults is either unknown or less potent.32 Only two programs with a focus on emerging adults have some evidence of recidivism reduction effectiveness in the general population. Both programs delivered developmentally appropriate helps (e.g. going to to housing vocational or educational needs) for justice system-involved growing adults in the community.33 34 Though limited in their study design in each study the specialized intervention group experienced better recidivism outcomes than the control group highlighting the potential power of targeting growing adults’ unique developmental challenges in the context of recidivism reduction methods.33 34 Though there is argument about whether treatment of SMHC contributes to reduced recidivism (e.g. 35 there is little debate concerning the appropriateness of ensuring that offenders with SMHC get good MH treatment as part of pre- or post-plea court diversion 38 39 or as part of justice system community supervision.40 Further malleable risk factors for offending among those with SMHC are similar to those in the general Caffeic Acid Phenethyl Ester population including school failure 41 alcohol and compound use 41 unemployment 46 poverty 36 and homelessness.48 49 Thus recidivism reduction approaches for growing adults with SMHC should include provision of good mental health care and approaches to reduce recidivism that address the changing nature of recidivism correlates during the change from adolescence to mature adulthood. As youth mature some of the factors that cause delinquent behavior dissipate or evolve into adult versions of those causes. For example parents no longer exert a direct supervisory and monitoring part (e.g. 50 51 during growing adulthood but family members continue to provide important resources (e.g. work in family business or with family friends) emotional support (e.g. encourage remaining out of problems) and a safety net (e.g. move back home when self-support fails).52-54 Similarly.
