The results show that youths who are poor, impulsive, poorly supervised by their parents, and exposed to deviant friends are more likely, for the same degree of antisocial behavior, to undergo intervention by the Juvenile Court, and that this intervention greatly increases the likelihood of involvement with the penal system in adulthood. The results also show that the various measures recommended by the Juvenile Court exert a differential criminogenic effect; those that involve placement have the most negative impact.

Preventing the creation and participation in such gangs should reduce the frequency of antisocial behaviour during adolescence.

Rather than decreasing recidivism, juvenile court intervention increased both violent and nonviolent future crimes. Along with previous studies, this study highlights a pressing need for more research and knowledge transfer about effective interventions to reduce recidivism among youths who commit crime.

Although a lot of research has been conducted on the delinquency of boys who are members of gangs, only a few quantitative studies have analysed the involvement of girl gang members in delinquency and its link with victimisation. In this study, the prevalence rates of girls who are members of gangs in Italy and in Switzerland are shown. We compared the Italian data (N=5.784) and Swiss data (N=3.459) from the second wave of the International Self-Reported Delinquency Study (ISRD-2); the population used for this comparison was made up of teenagers from the ages of 13 to 16. Members of deviant youth groups accounted for 5.7% of the Italian sample and 4.7% of the Swiss sample; in both countries, about a third of gang members were girls. In general, girls who are members of gangs commit more delinquent acts than both girls and boys who are not members of gangs. Girl gang members are also more often victimised than girls and boys who are not members of a deviant youth group.
