The authors observed stuttering adults are at risk of social anxiety disorder, and, young people who stutter are at risk for the development of anxiety. The timing of anxiety onset related to stuttering is unclear, which is due to a range of methodological limitations in the research evidence. The authors proposed that it is likely anxiety related to stuttering increases over time, exceeding normal levels in adults.
