Among concerns we discuss are: (1) continued disconnects between basic science to understand the nature of stuttering and the therapies we employ with our clients; (2) a need for better understanding of causal mechanisms and mediators of change in stuttering interventions; and (3) specific challenges that make it difficult to know if therapies for early stuttering work significantly better than spontaneous recovery.

The study was based on semi-structured interviews with 10 adults with developmental stuttering who had previously participated in the active tDCS stimulation group. Data were analyzed using inductive thematic analysis. Five main themes were identified: (1) reasons for participation; (2) perception of the intervention and emotional responses; (3) experiences related to the intervention process; (4) perceived effects of tDCS and (5) recommendations for the future. Participants reported temporary fluency improvements and increased self-confidence, emphasizing that the intervention was generally manageable and acceptable. These subjective evaluations offer insight into how tDCS was experienced without implying clinical efficacy. Results should be interpreted with caution, as interviews were conducted without blinding and responses may have been influenced by social desirability or complicity bias. Importantly, despite prior quantitative measurements from the same intervention showing no significant objective improvements in speech fluency, participants still described positive subjective experiences.

The sample of this study consisted of 145 adults, including 65 PWS, 80 PWNS. Data were collected using a Personal Information Form, the Fear of Missing Out Scale for University Students, and the Brief Resilience Scale (BRS). Analyses were conducted using IBM SPSS 26.0 with a multivariate Generalized Linear Model (GLM) and correlation analyses. PWS scored significantly higher in the social dimension of FoMO, suggesting that PWS may experience greater anxiety about missing out in social contexts compared to PWNS. No significant differences were found between PWS and PWNS in terms of their total or private FoMO scores. Age and gender did not significantly affect FoMO scores. In contrast, PWS exhibited significantly lower psychological resilience compared to PWNS. While age had no significant impact on resilience, gender showed a significant effect on resilience in both groups. Men had significantly higher levels of psychological resilience than women. Additionally, a negative correlation was observed between FoMO and psychological resilience in both groups, suggesting that higher FoMO is associated with lower resilience.
