This study was to examine the background and formative factors for delinquency recidivism of 18- and 19-year-old male juvenile delinquents (n = 132) admitted to a juvenile classification home, focusing their family environment, life history and personal factors in particular, based on official records and questionnaire. As the result of analyzing formative factors for delinquency recidivism by use of covariance structure analysis, the two factors such as bad self-image and the belonging to delinquency groups as direct risk factors for delinquency were identified. These two factors resulted from dropping out of school and job, the causes of which were negative factors in family environment or low self-control. Negative factors in family environment and low self­ control were, however, indirect risk factors for delinquency recidivism. As the model for delinquency recidivism formation, the validity of a comprehensive delinquency theory centering on control theory to make a point of the involvement in family, school and workplaces, taking into consideration perspectives such as the theory of self-concept and delinquency groups as a reference group was suggested.
