Not Anxiety but Self‐Regulatory Capacity and Age Predicts Self‐Reported Stuttering Severity in Adults Who Stutter (AWS)

What is already known on this subject Previous findings on stuttering have indicated moderate environmental contributions to its aetiology, but little remains known of the specific environmental influences, especially in adulthood. Most psychological research has studied different variables independently without much consideration of their underlying relationships. What this paper adds to existing knowledge Psychosocial variables were found to have an indirect effect on self-reported stuttering in adulthood through the latent construct of self-regulatory capacity (C). Age also accounted for a small to moderate effect. This study adds to the literature by expanding our understanding of the key variables involved in stuttering among adults. What are the potential or actual clinical implications of this work? Interventions can aim to improve C in this population while adapting treatment according to age. The identified psychosocial variables can help identify sub-groups at the highest risk of greater stuttering severity. Clinical implications include a greater understanding and targeting of the factors most likely to improve stuttering for adults who stutter (AWS).
