Dj. Flannery et al., Who are they with and what are they doing? Delinquent behavior, substance use, and early adolescents' after-school time, AM J ORTHOP, 69(2), 1999, pp. 247-253
The relationship among after-school time, parental monitoring, and problem
behavior was examined in a sample of 1,170 early adolescents. Those spendin
g unsupervised time with peers reported higher levels of aggression, delinq
uency, substance use, and susceptibility to peer pressure, and lower levels
of parental monitoring, than did adolescents at home with parents. Adolesc
ents home alone after school were similar to those who spent time with adul
ts or in school activities.
