title: Investigating personality in stuttering: results of a case control study using the NEO-FFI.
abstract: A recent study by Iverach et al. (Journal of Communication Disorders, 2010) compared persons who stutter with two normative samples in the context of the five-factor model of personality measured by the NEO Five-Factor Inventory (NEO-FFI). Persons who stutter were characterized by higher Neuroticism, lower Conscientiousness and lower Agreeableness scores in contrast to the normative data from an Australian and a United States sample. Moreover, the authors report that the scores on all five personality dimensions in the stuttering group were within those of the normative samples. A shortcoming of the Iverach et al. study is the lack of a matched control group. In the present study we compared persons who stutter with a control group matched to age and gender. Furthermore, none of the controls had a history of personal and family stuttering. The findings with respect to Neuroticism could be replicated in our sample. But in contrast to Iverach et al. we found higher Conscientiousness and Agreeableness scores in persons who stutter compared to the control group.
  
  
  OBJECTIVE
  The reader of the present study will learn that elevated Neuroticism scores can be observed in persons who stutter across cultures such as Germany or Australia. With respect to other personality dimensions such as Conscientiousness or Agreeableness the picture is much more difficult.
