Data analysis revealed three factors in each stage of observation: entrance into homes (adaptability, moderation, and childishness); meetings with parents (closeness between juveniles and parents, mutual dependence between juveniles and parents, and moderation of juveniles); daily living (attitude to norms, sociability, and double dealing); sports activities (willingness to participate, desire to attract attention, and obedience); and diaries (reflective attitudes, writing ability, and honesty). Relations between the preceding factors and juvenile attributes such as age, sex, intelligence, former home detention, delinquent behavior type, connection with delinquent groups, and problem behavior patterns in homes were analyzed. Two factors, adaptability and childishness, appeared to have clear positive or negative relations with many juvenile attributes. Most juveniles with poor adaptability belonged to younger age groups and had poor social skills and moral consciousness. Many juveniles who showed childish behaviors did not have serious delinquent tendencies and still maintained emotional relations with their parents. The factor reflecting honesty had an inverse relation with juveniles' behavioral problems during their stay in homes.
