The experience of stuttering in everyday life among adults who stutter: The impact of trait social anxiety and the social situations

Purpose: The purpose of this study was to investigate the emotional and stuttering experience of adults who stutter (AWS) in everyday life, and how that experience may be shaped by personal (i.e., trait social anxiety) and situational factors (i.e., social partner reaction, communication channel type, social closeness, stuttering knowledge). Method: AWS completed ecological momentary assessments on their smartphones multiple times a day for up to three weeks. Data (n = 62) were analyzed with multilevel models to determine how situational factors and trait social anxiety influence the Negative Affect (NA), Positive Affect (PA), and self-reported stuttering severity of AWS. Results: Results indicated that having high (vs. low) trait social anxiety was associated with a tendency to experience high NA, low PA, and high self-reported stuttering severity among AWS. A range of situational factors significantly influenced the within-person variation of NA, PA, and self-reported stuttering severity in everyday life. In addition, interacting with distant social partners relative to being alone heightened NA, and the effect was more prominent among AWS with high (vs. low) trait social anxiety. Conclusions: Overall, the findings suggest that the variation of affects and stuttering severity among AWS can be partly accounted for by factors from both the situational and personal levels. Clinicians should be aware of the low PA experienced by AWS who have high (vs low) trait social anxiety in everyday life.
