tudy was a longitudinal study of 177boys. These boys were gathered having disruptive behavior disorders. The participants were 7 to 12 years of age. The sample was composed of white(70%) and african-americans(30%). The procedures for this experiment were to conduct an annual assessment between 1987 and 1994. It was conducted with the boy and his parents. The test given to the participants in the interviews was a parallel version of the National Institute of Mental Health Diagnostic Interview Schedule for Children(DISC.)

These disorders were recorded after and during the 7 year period. In conclusion, to the study it was shown that persistent fighters of having 2 or more diagnosis during year 7 was more than 3 times higher than the prevalence among non-fighters according to the results of the reports given from the interviewers. Persistent fighters were more likely than non-fighters to have Conduct Disorder in year 7. The present article has both strengths and weaknesses. In this article the boys were gathered from clinics where they were reported to have already had problems. This is an issue because the boys socioeconomic status was not accounted for nor was any traumatic events that might have taken place during the time of testing. Also interviewing annually leaves to much time for other variables to harm the research. The assessment was not continuous through the 7 year period. The sample was also taken from one geographical area which could skew the results considering the social and cultural differences. The data taken from this study did support the hypothesis. There are alternative ways t...
