Abstract. Staff assumptions and program practices in two models of residential care for male adolescent offenders were compared. Group care settings had from 6 to 15 youths in residence and used peer-mediated treatments. Treatment Foster Care settings had one youngster placed in each home and treatments were adult-mediated. Results showed that group care and Treatment Foster Care program models differed on staff assumptions about therapeutic mechanisms of change, and different patterns of daily program practices were found.
