The Long-Term Effects of the Youth Crime Prevention Program "New Perspectives" on Delinquency and Recidivism

Effectiveness, working mechanisms, and implementation of youth-initiated mentoring for juvenile delinquents: a multiple-methods study protocol

BACKGROUND

The societal costs associated with juvenile delinquency and reoffending are high, emphasising the need for effective prevention strategies. A promising approach is Youth-Initiated Mentoring (YIM). In YIM, professionals support youths in selecting a non-parental adult from within their social network as their mentor. However, until now, little (quasi-)experimental research has been conducted on YIM in the field of juvenile delinquency. We will examine the effectiveness, working mechanisms, and implementation of YIM as a selective prevention strategy for juvenile delinquents.

METHODS

This multiple-methods study consists of a quasi-experimental trial and a qualitative study. In the quasi-experimental trial, we aim to include 300 juvenile offenders referred to Halt, a Dutch juvenile justice system organisation which offers youths a diversion program. In the Netherlands, all juvenile offenders between 12 and 18 years old are referred to Halt, where they must complete the Halt intervention. Youths will be non-randomly assigned to region-matched non-YIM-trained and YIM-trained Halt professionals implementing Care as Usual (CAU, i.e., the Halt intervention) or CAU plus YIM, respectively. Despite non-random allocation, this approach may yield comparable conditions regarding (1) the characteristics of professionals delivering the intervention and (2) case type and severity. Youth and caregiver(s) self-report data will be collected at pre-and post-test and a 6-month follow-up and complemented with official Halt records data. Multilevel analyses will test whether youths following CAU plus YIM show a stronger increase in resilience factors and a stronger decline in the need for formal support and delinquency than youths following CAU. In the qualitative study, we will organise focus group interviews with YIM-trained professionals to explore boosters and barriers experienced by professionals during the implementation of YIM.

DISCUSSION

The proposed study will help identify the effectiveness of YIM in strengthening resilience factors and possibly decreasing juvenile delinquency. In addition, it may offer insights into how and for whom YIM works. Finally, this study can help strengthen the implementation of YIM in the future.

Youth Initiated Mentoring: A Meta-analytic Study of a Hybrid Approach to Youth Mentoring

Youth initiated mentoring is a hybrid approach that empowers youth to identify and recruit natural mentors, potentially combining the strengths of informal mentoring relationships with the infrastructure and support provided by formal mentoring programs. This meta-analytic review examined the association between youth-initiated programs and youth outcomes across four domains: academic and vocational functioning, social-emotional development, physical health, and psychosocial problems. Results indicated that youth-initiated programs are significantly associated with positive youth outcomes. There was a small-to-medium effect size of g = 0.30 for youth-initiated programs overall, which was based on 14 studies with 11 independent samples (3594 youth and 169 effect sizes) from 2006 to 2019. The effect size was somewhat larger (g = 0.40) when controlling for possible selection bias, and was moderated by participant gender and year of publication. Implications for theory and practice regarding this relatively new approach to mentoring are discussed.
