Early Intervention and Juvenile Delinquency Prevention...

Early Intervention and Juvenile Delinquency Prevention: Evidence from the Chicago Longitudinal Study (CLS) (Mann, E. A., Reynolds, A. J., 2006). The Chicago Longitudinal Study (CLS) was a quasi-experimental design study which investigated the role of Child-Parent Center (CPC), early education intervention (independent variable) and child, family, peer and school-level predictors on court-reported juvenile delinquency (dependent variable). The predictor variables used have been supported through extensive research and included: early antisocial behavior, individual-level attributes of the child family attributes, and social characteristics of both the child and the family (Lipsey Derzon, 1998). This prediction model was utilized to†¦show more content†¦Delinquency data was drawn from government records and included rates, frequency and type of delinquency. Finally, social service data offered data on child maltreatment. The combination of these variables provides a holistic perspective of factors that do contribute to delinquency. For instance, the study looked at familial factors such as low educational attainment a nd parental supervision, which are independent predictors of delinquency (Zigler el al., 1992). On the other hand, the use of secondary data may have jeopardized the validity. What if a delinquent act was not captured, due to incorrect records, then the record would provide a false negative. One major weakness of the study is the sampling methods which limited both the internal and external validity. First, the children were not randomly selected from the population, jeopardizing external validity. The authors explain that was random selection was not utilized within the study because they drew their sample from the pool of students already participating in the intervention (CPC program) (p. 157). It is understandable that the sample could not be drawn from the population randomly but randomization could have been used to address internal validity. Second, the lack of randomization may have caused selection bias, a threat to internal validity. The authors didn’t explain how students were selected into theShow MoreRelatedThe Effects Of Juvenile Delinquency On Teens864 Words   |  4 Pagesunderdevelopment, deficiency and lack of housing areas.

In fact, the notion of childhood and adolescence as distinct phases of human development is a novel idea that did not truly emerge until the twentieth century, so it is only natural that some elements of the juvenile justice system seem to have been made up they went along.

There is little evidence that this vein of research ideas will soon run dry. This is not to say that Hirschi’s theorizing has been universally popular. His frameworks are bold—critics would say pretentious (Geis, 2000)—because they claim to be â€Å"general theories† that explain crime across types of crime and types of people. Hirschi also has shown little interest in race,class,and gender inequalities that others—especially those from more critical perspectives—see as fundamentalRead MoreFactors Affecting Class Attendance of Selected Bachelor of Science in Cruise Line Operatons Students6991 Words   |  28 Pages... 5 Scope and Limitation of the Study .............. 5 Significance of the Study ...................... 5 Definition of Terms ............................ 6 2.
