Self-reported anxiety of adults who do and do not stutter.

This is a preliminary investigation of the differences in self-reported anxiety of people who do and do not stutter. Participants and experimental procedures were the same as those used by Gabel, Colcord, and Petrosino in 2001. 10 people who stuttered, all of whom had experience with stuttering therapy, were matched with 10 participants who did not stutter. Each participant in both groups was engaged in a session to evaluate speech in a format similar to a professional diagnostic session for stuttering. Each participant was stopped and asked to rate his anxiety during specific moments during the session. This procedure is similar to in vivo cognitive assessment used in cognitive-behavioral treatments and research. The participants' reports were taken during a baseline period, during a period in which they were thinking about their speech, and during three different speaking tasks. The anxiety reported by the group of people who stuttered was compared to the anxiety reported by the group of individuals who did not stutter. Statistical analyses indicated a significant main effect for the group who stuttered as they reported more anxiety during the entire session. There was no main effect for condition. The interaction of group by condition fell short of significance. Possible explanations and suggestions for research were discussed.
