In this study, classification into two types of antisocial behavior (Adolescence-Limited and Life-Course-Persistent) by Moffitt (1993) that had the purpose to explain the age-crime curve was attempted by using the data collected upon differentiating the quality of 1,440 juvenile delinquents who entered a Juvenile Classification Home, to examine consistency with her theory. As a result, a significant difference was recognized in the situation of school maladaptation, initial misbehavior in the early years, etc. between the two groups classified, and some differentiation materials were also indicating possible classification into two groups close to Moffitt’s theory. From the comparison of both groups, it was confirmed that the degree of the problem was more significant for Life-Course-Persistent than Adolescence-Limited: however there was no clear difference in the number and content of delinquency factors for both groups, and the structural difference in the explanatory model of delinquency was not successfully confirmed either.
