Seven author-contributed papers address theoretical and applied interventions with children who have behavior disorders. V. Rezmierski reviews the developmental perspective and the Intervention by Prescription model in "Developmental Interventions with Behaviorally Disordered Youth." D. Glenn et al. follow with a discussion of research and theory on "Cognitive Approaches to Social Competence with Behaviorally Disordered Youth." P. Nichols ("Down the Up Staircase: The Teacher as Therapist") examines myths concerning psychotherapy and addresses ways in which teachers can incorporate intentional psychology instruction. In the first of the application papers ("Supportive Peer Groups--A Behavior Management Program for Children") T. Virden outlines a behavior management program in which children analyze their own and others' behavior. A structured learning approach for teaching pro-social behavior is discussed by E. McGinnis in "Teaching Social Skills to Behaviorally Disordered Youth." Descriptions of two intervention approaches--"Teaching Independent Student Behaviors to Behaviorally Disordered Youth" (V. Brown) and "Teaching Social Routines to Behaviorally Disordered Youth" (R. Neel) conclude the monograph. (CL)
