TL;DR: In this paper, the authors draw on the results of the major Pittsburgh Youth Study complemented by follow-up tracking of juvenile court records for more than six years to address the following questions: *What is the prevalence and age of onset of delinquency, substance use, and early sexual behavior for three samples of boys age 8, 11, and 14? What are the average mental health problems for these ages?

TL;DR: In this paper, the authors traced developmental sequences in disruptive behavior from childhood to adolescence in two community samples of boys and identified three developmental pathways: (a) an early authority conflict pathway, consisting in sequence of stubborn behavior, defiance, and authority avoidance; (b) a covert pathway consisting of minor covert behaviors, property damage, and moderate to serious forms of delinquency; and (c) an overt pathway, including aggression, fighting, and violence.

TL;DR: This article found that ethnic differences in official delinquency were partly attributable to ethnic differences of delinquent behavior and were not attributable to differential ethnic attrition or differential ethnic validity of measures of delinquent behaviour.

TL;DR: In this paper, the concurrent and predictive influence of deviant peers on boys' disruptive and delinquent behavior was examined in a community sample of fourth and seventh-grade boys, who were followed-up over six data waves.
