In a variety of treatment settings, a therapeutic milieu provides intensive psychotherapeutic and psychoeducational experiences for disturbed children and young adolescents. It is generally agreed that effective psychosocial treatment requires a developmentally based treatment approach, collaborative parental involvement, and provision for ongoing staff support and training. In such settings, the treatment plan for each child reflects developmental, psychosocial, biological, cognitive, and neurointegrative aspects of the child's problems and identifies specific roles for psychotherapists, caseworkers, educators, occupational and recreational therapists, and parents (Alt, 1961; Pfeffer, 1979; Redl, 1959; Trieschman, 1969).
