Although “Japanese Approved Schools” are facilities for children and youths who have not been cared for appropriately by their parents, little is known about them and no research undertaken to characterize them. These facilities prevent youth from committing delinquent acts, and protect juveniles from maltreatment as social welfare facilities for children and youths. This is the first study to clarify what Japanese approved schools are and what traits the juveniles have. This current study examined main hypothesis that the subject group would have particular psychological traits and developmental disturbances. Participants were thirty-six juveniles (male=24, female=12) between ages11-18. Many of them have been exposed to parental abuse severely and exhibited serious antisocial behavior. The results of self-report questionnaires suggested that they have a low self-esteem and serious depressive symptoms. In addition, they showed AD/HD symptoms such as inattention, impulsivity, and hyperactivity. Our findings suggest that the subjects have negative emotional traits and multidimensional developmental disturbances. Findings and limitations in current study were discussed. Future research should focus on examining the efficacy of such facilities and utility of these services for juveniles.
