Evaluation of a regional resource center for multiply handicapped retarded children.

A modified before--after, control-group evaluation design was employed to assess the impact of a demonstration program for multiply handicapped retarded children. Child development, parent and therapist attitudes, and knowledge and use of services were evaluated. Findings revealed no significant positive impact of the program on development, attitudes, and knowledge; the treatment group used more services. A significant change to a more negative attitude on the part of the treatment-group parents with regard to some aspects of normalization was found. Major impact of the program was in the area of coordination of services.
