Reported were the development and testing of a therapy program for stutterers which aimed at involving parents in the treatment process. The experimental therapy program was developed and applied to a group of 13 parent child dyads whose interaction patterns were analyzed in an attempt to identify factors pertinent to the child's stuttering. Therapeutic strategies were developed on the basis of observed parent maintenance of stuttering behaviors. Children were found to generalize their increased fluency, acquired with a therapist, to their respective parents. Positive changes in parental verbal behavior were observed. The feasibility of employing the therapy program in a school setting was tested with 13 children. The program was found to be successful in managing stuttering and feasible from the viewpoint of school administrators. Categorization of parent child interactions into 35 thematic content categories was thought to provide crucial information relating to possible maintenance factors of stuttering. It was found that parents of stutterers consistently yielded more negative profiles on the basis of the categories than did parents of nonstutterers. (Author/GW)
