MMPI Profiles Of Stutterers’ Parents: A Follow-up Study

Abstract

The author cross-validated with a typical speech clinic group of children approximately 10 years of age, the findings of a previous study that had found no major differences in the Minnesota Multiphasic Personality Inventory profiles of a group of 100 parents of stutterers and 100 parents of non-stutterers. Case records of 50 stuttering children and their parents were drawn from the files of Iowa Speech Clinic and the 100 profiles were compared with the results of the previous study. Only 3 significant mean differences were found and comparisons of the high-point codes of the follow-up parents and of the 2 original groups revealed no significant differences. The study is interpreted as confirming the conclusions of the prior study that the etiology of stuttering is not related to severe psychopathology on the part of stutterers'' parents.
