An individual plan for effective parent involvement is developed with consideration given to levels of parent/child interaction and to the parents' ability to accept their child's difficulties. Purposes of parental participation are outlined in conjunction with an existing model for evaluation and intervention. A case presentation is presented which illustrates optimal parental involvement and the resulting positive outcomes.
