Repetitive Negative Thinking, Temperament, and Adverse Impact in Adults Who Stutter

Abstract

Purpose Prior research has explored how repetitive negative thinking (RNT) contributes to both the increased persistence and severity of various disorders, such as depression, anxiety, and eating disorders. This study explored the potential role of RNT in the experience of stuttering, with a particular focus on the relationship between RNT, adverse impact, and certain temperament profiles. Method Three hundred thirteen adults who stutter completed a measurement of the frequency/severity of RNT (Perseverative Thinking Questionnaire; Ehring et al., 2011), 207 completed a temperament profile (Adult Temperament Questionnaire; Evans & Rothbart, 2007), and 205 completed a measurement of adverse stuttering impact (Overall Assessment of the Speaker's Experience of Stuttering; Yaruss & Quesal, 2016). Analyses were conducted within and across instruments to ascertain how RNT, temperament markers, and adverse impact interrelate within individuals. Results Results indicated that RNT significantly predicts Overall Assessment of the Speaker's Experience of Stuttering impact scores with great effect and that certain temperament markers (specifically, Effortful Control and Negative Affectivity) moderate this relationship for specific sections of the Overall Assessment of the Speaker's Experience of Stuttering. Conclusion By assessing RNT in people who stutter, clinicians can better understand individual differences in their clients, and this will allow them to make targeted diagnoses and develop more tailored intervention plans.
