This study aimed to identify the relationship between MBTI personality types and parent-child relationships among the juvenile delinquents non-delinquent adolescents. From the analyses of empirical data, the following tendencies were found. First, delinquent juveniles are more likely to be classified to be such MBTI types as "Extroverted," "Sensing," "Thinking," and "Judging" than non-delinquent juveniles. Second, contrary to popular belief, the juvenile delinquent group was fecund to have more positive attitudes toward their relationship with their parents than the non-delinquent juvenile group. Third, for both the non-delinquent juveniles and the delinquent juveniles, "I" and "P" preferences were related with a positive perception of the relationship with their parents. Fourth, "EJ," as a psychological temperament type, was related with a Positive relationship with parents for both groups. Fifth, the psychological function types were not significantly related with the relationship with parents. Sixth, "EP" and "IP," as psychological attitudes types, were related significantly with a positive relationship with parents. Seventh, the juveniles classified as "ESTJ" had good relationships with parents, whereas "ISTP" types, on the other hand, tended to show the most negative attitudes toward their relationship with parents. The most interesting result of this study was the finding that the "P (perceiving)" types in the non-delinquent juveniles group as well as in the juvenile delinquents group tend to have negative attitudes toward their parents.
