Service delivery systems for maltreating parents need to be comprehensive, integrated, and coordinated in order to address the ecological, developmental, and psychotherapeutic needs of maltreating families. This article presents a center-based, intensive model of intervention for multiproblem, maltreating families. The program described addresses the needs of the entire family; incorporates the evaluation and treatment of the child's, as well as the parent's, development; and provides services in a multifamily group milieu. The following interventions are integrated in the treatment approach: (1) family milieu approach, (2) assistance with functioning of the ''parental ego,'' (3) traditional therapies, and (4) developmental-structuralist approach to parent-child interaction. Challenges encountered and solutions employed in working with maltreating families are discussed. A detailed case study is presented to illustrate the types of interventions used.
