“…Examining individual risk factors for youth involved with the legal system is essential in reducing the likelihood of reoffending. Substance use (SU) is among the factors routinely assessed at intake to the JJ system in reviewing recidivism risk (Baglivio, 2009 ) because of its strong association with delinquent behavior (DeLisi et al, 2015 ; Dembo et al, 1997 ; Leukefeld et al, 2017 ; Mulvey et al, 2010 ), and recidivism (Hoeve, McReynolds, & Wasserman, 2014 ; McReynolds et al, 2010 ; Robertson et al, 2020 ; Stoolmiller & Blechman, 2005 ; Van der Put et al, 2014 ). Youth in the juvenile justice system have substantially higher rates of alcohol, marijuana, and cocaine use compared with youth in the general population (Miech et al, 2018 ; Mieczkowski et al, 1998 ; Mulvey et al, 2010 ), with approximately 51% of youth involved with community supervision having SU problems requiring treatment (Scott et al, 2019 ).…”
