Stuttering generalization self-measure: Preliminary development of a self-measuring tool

- It is important to consider assessing stuttering in naturalistic speaking situations.
- The relationship between stuttering and related anxiety can influence the outcome.
- SGSM can discriminate between PWS and controls in terms of fluency and speech anxiety levels.
- SGSM can serve as desensitizing treatment agent.
- SGSM can assess stuttering and related anxiety within the same speaking situation.

IntroductionGeneralization of treatment is considered a difficult task for clinicians and people who stutter (PWS), and can constitute a barrier to long-term treatment success. To our knowledge, there are no standardized tests that collect measurement of the behavioral and cognitive aspects alongside the client's self-perception in real-life speaking situations.PurposeThis paper describes the preliminary development of a Stuttering Generalization Self-Measure (SGSM). The purpose of SGSM is to assess 1) stuttering severity and 2) speech-anxiety level during real-life situations as perceived by PWS. Additionally, this measurement aims to 3) investigate correlations between stuttering severity and speech-anxiety level within the same real-life situation.MethodThe SGSM initially reported includes nine speaking situations designed that are developed to cover a variety of frequent speaking scenario situations. However, two of these were less commonly encountered by participants and subsequently not included in the final analyses. Items were created according to five listener categories (family and close friends, acquaintances, strangers, persons of authority, and giving a short speech to small audience). Forty-three participants (22 PWS, and 21 control) aged 18 to 53 years were asked to complete the assessment in real-life situations.ResultsAnalyses indicated that test-retest reliability was high for both groups. Discriminant validity was also achieved as the SGSM scores significantly differed between the controls and PWS two groups for stuttering and speech-anxiety. Convergent validity was confirmed by significant correlations between the SGSM and other speech-related anxiety measures.
