Juvenile Delinquency - Juvenile Delinquents Diagnosed With Mental/conduct Disorders

Juvenile Delinquents Diagnosed With Mental/conduct Disorders

Juvenile delinquents are often diagnosed different disorders. Around six to sixteen percent of male teens and two to nine percent of female teens have a conduct disorder. These can vary from oppositional-defiant disorder, which is not necessarily aggressive, to antisocial personality disorder, often diagnosed among psychopaths. A conduct disorder can develop during childhood and then manifest itself during adolescence.

Juvenile delinquents who have recurring encounters with the criminal justice system, or in other words those who are life-course-persistent offenders, are sometimes diagnosed with conduct disorders because they show a continuous disregard for their own and others safety and/or property. Once the juvenile continues to exhibit the same behavioral patterns and turns eighteen he is then at risk of being diagnosed with antisocial personality disorder and much more prone to become a serious criminal offender. One of the main components used in diagnosing an adult with antisocial personality disorder consists of presenting documented history of conduct disorder before the age of 15. These two personality disorders are analogous in their erratic and aggressive behavior. This is why habitual juvenile offenders diagnosed with conduct disorder are likely to exhibit signs of antisocial personality disorder early in life and then as they mature. Some times these juveniles reach maturation and they develop into career criminals, or life-course-persistent offenders. "Career criminals begin committing antisocial behavior before entering grade school and are versatile in that they engage in an array of destructive behaviors, offend at exceedingly high rates, and are less likely to quit committing crime as they age."

Quantitative research was completed on 9,945 juvenile male offenders between the ages of 10 and 18 in the 1970s. The longitudinal birth cohort was used to examine a trend among a small percentage of career criminals who accounted for the largest percentage of crime activity. The trend exhibited a new phenomenon amongst habitual offenders. The phenomenon indicated that only 6% of the youth qualified under their definition of a habitual offender (known today as life-course persistent offenders, or career criminals) and yet were responsible for 52% of the delinquency within the entire study. The same 6% of chronic offenders accounted for 71% of the murders and 69% of the aggravated assaults. This phenomenon was later researched among an adult population in 1977 and resulted in similar findings. S.A. Mednick did a birth cohort of 30,000 males and found that 1% of the males were responsible for more than half of the criminal activity. The habitual crime behavior found amongst juveniles is similar to that of adults. As stated before most life-course persistent offenders begin exhibiting antisocial, violent, and/or delinquent behavior, prior to adolescence. Therefore, while there is a high rate of juvenile delinquency, it is the small percentage of life-course persistent, career criminals that are responsible for most of the violent crimes.
