Observer-rated outcomes of communication-centered treatment for adults who stutter: A social validation study.

Previous studies have reported that adults who stutter demonstrate significant gains in communication competence, per self-ratings and clinician-ratings, upon completion of a communication-centered treatment, or CCT. The purpose of this social validation study was to determine whether communication competence ratings reported by untrained observers are consistent with client and clinician judgments of communication competence gains following CCT. Eighty-one untrained observers completed an online survey that required each to view one of two videos depicting an adult who stutters during a mock interview recorded prior to CCT or after CCT. Observers were then asked to rate the communication competence of the interviewee on a 100-point visual analog scale and provide additional demographic information. Communication competence of the adult who stutters who had completed CCT was rated significantly higher in their post-treatment video. Upon controlling for two demographic factors found to be associated with observer ratings (years of education, years the observers had known an adult who stutters), significantly higher ratings of communication competence for the post-treatment video were maintained. These preliminary findings provide social validity for CCT by demonstrating that the gains in communication competence reported in previous studies through clinician and client observations are also reported by untrained observers who are not familiar with CCT.

Self-Perceived Communication Competence of Adults Who Stutter Following Communication-Centered Treatment.

PURPOSE: The purpose of this study was to assess self-perceived communication competence of adults who stutter following participation in a non-ableist treatment for which one of the core components focuses on communication - with no direct or indirect goals designed to reduce or modify stuttered speech. METHOD: Thirty-three adults who stutter completed the Self-Perceived Communication Competence scale (McCroskey & McCroskey, 1988) pre- and posttreatment. RESULTS: Findings indicate significant gains in self-perceived communication competence posttreatment. Pre- to posttreatment changes in stuttering did not predict posttreatment gains in self-perceived communication competence. CONCLUSION: The present study demonstrates that improvement in communication can be achieved independent of improvement in fluency, lending further support to the notion that stuttering and communication competence are distinct constructs.

Speech disfluencies in bilingual Greek-English young adults.

PURPOSE: The purpose of this study was to investigate the frequency and types of disfluencies in Greek-English bilingual adults across naturalistic speech samples and compare frequency and types of disfluencies between the participants' L1 and L2. METHODS: Participants in the study included 26 Greek-English bilingual young adults. All participants were sequential bilinguals, whose first language was Greek and second language was English. Two speech samples were collected in each language, a conversational and a narrative sample, which were subsequently analyzed for the frequency and types of disfluencies. RESULTS: Results indicated that participants produced more typical disfluencies in English compared to Greek across speaking samples. The most frequent types of disfluencies were filled pauses and vowel prolongations (without tension or struggle) across speaking samples and languages. CONCLUSION: Our results revealed differences in the types and frequencies of disfluencies produced in participants' native compared to their second language. Results add to the growing body of literature addressing the manifestation of speech disfluencies in bilingual speakers.

Impact of self-disclosure and communication competence on perceived listener distraction.

PURPOSE: The purpose of this study was to investigate the distraction reported by unfamiliar adults when listening to a speaker who stutters, and whether listener distraction is influenced by two factors: self-disclosure and communication competence. METHOD: Two hundred seventy-five adults watched a video vignette and were asked to rate their level of distraction when observing an adult Latinx male producing stuttered speech. Each participant watched one of six randomized videos of the same speaker sharing the same content systematically manipulated by (a) presence or absence of 15% stuttering, (b) presence or absence of self-disclosure, and (c) high or low communication competence. RESULTS: Listener distraction was higher when rating speakers with low communication competence, regardless of whether stuttering or self-disclosure were heard. Videos wherein the speaker was fluent were rated as significantly less distracting, but only in the context of high communication competence. For videos wherein the speaker stuttered, listeners reported significantly less distraction when the speaker demonstrated high communication competence and self-disclosed. FINDINGS: These findings suggest that for persons who stutter, high communication competence and disclosing that they stutter will yield maximum reduction in listener distraction.

The Impact of Self-Disclosure and Strategies for Communication Competence on Professors' Perceptions and Evaluations of Students Who Do and Do Not Stutter.

PURPOSE: The purpose of this study was to examine the impact of self-disclosure and strategies for communication competence on perceptual ratings and performance evaluations of undergraduate students who do and do not stutter by professors who require oral presentations. METHOD: Two hundred thirty-eight college instructors who require oral presentations in their classes participated in this study. Each participant viewed one video of six possible randomized conditions varying according to the presence and disclosure of stuttering (i.e., fluent, stuttering, stuttering + disclosure) and level of communication competence (i.e., high vs. low). Participants evaluated public speaking performance against a standardized rubric and rated the student along 16 personality traits. RESULTS: Results of separate 2 × 3 analyses of variance revealed that professors perceived a student who disclosed stuttering, compared to the identical video without disclosure, more positively overall. Significant interactions between fluency (i.e., presence vs. absence of stuttering vs. disclosure of stuttering) and communication competence (i.e., high vs. low) were found for overall performance evaluation scores. The video during which the student disclosed stuttering and presented with low communication competence was given a higher score than the identical video without disclosure. CONCLUSIONS: Professors respond positively to both strategies for high communication competence and self-disclosure. High communication competence behaviors mitigate positive feedback bias. Disclosure results in improved positive perceptions across levels of communication competence. For students presenting with low communication competence, disclosure may improve evaluation of performance in oral presentations. The greatest perceptual and evaluative benefits were achieved with the combination of the two strategies.

Professors' Perceptions and Evaluations of Students Who Do and Do Not Stutter Following Oral Presentations.

PURPOSE: The purpose of this study was to examine the perceptual ratings and performance evaluations of students who do and do not stutter by professors who require oral presentations. Additionally, this study sought to investigate the influence of behaviors related to communication competence on perceptual and evaluative ratings. METHOD: One hundred fifty-eight college instructors who require oral presentations in their classes participated in this study. Participants viewed one video of four possible randomized conditions: (a) presence of stuttering + low communication competence, (b) absence of stuttering + low communication competence, (c) presence of stuttering + high communication competence, and (d) absence of stuttering + high communication competence. Participants evaluated student performance against a standardized rubric and rated the student along 16 personality traits. RESULTS: Results of separate 2 × 2 analyses of variance revealed professors' view and evaluate students presenting with high communication competence more positively overall, regardless as to whether stuttering is present or not. Significant interactions between fluency (i.e., presence vs. absence of stuttering) and communication competence (i.e., high vs. low) were found for negative personality traits, as well as delivery evaluation scores. The video for which the student stuttered and presented with low communication competence was rated more positively than the video for which the student did not stutter and presented with low communication competence. CONCLUSIONS: Professors perceive and evaluate students who stutter differently from their nonstuttering peers, and those ratings are moderated by levels of communication competence. High-communication-competence behaviors improved perceptual and evaluation scores; however, in the presence of low-communication-competence behaviors, professors overcorrect in the form of positive feedback bias, which may have negative long-term academic consequences.

Preliminary study of self-perceived communication competence amongst adults who do and do not stutter.

PURPOSE: Adults who stutter report a significant impact of stuttering on their quality of life, including negative thoughts and attitudes toward communication. In addition to this impact, adolescents who stutter also report lower levels of self-perceived communication competence (SPCC) compared to fluent peers. The purpose of this study was to extend the investigation of SPCC to adults who do and do not stutter. Additional aims investigated included if 1) SPCC predicted overall impact of stuttering, and, 2) stuttering frequency predicted SPCC among adults who stutter. METHODS: Twenty-four adults who stutter and twenty-seven adults who do not stutter matched for age, gender, and education completed the Self-Perceived Communication Competence Scale (Richmond & McCroskey, 1997). All participants who stutter completed the Overall Assessment of the Speaker's Experience of Stuttering (OASES [ages 18+]; Yaruss & Quesal, 2006) and speaking samples to measure stuttering frequency. RESULTS: Adults who stutter reported significantly lower SPCC scale total scores than adults who do not stutter. For adults who stutter, lower SPCC scale scores significantly predicted more severe overall impact of stuttering as measured by the OASES. Stuttering frequency did not predict SPCC scale scores. DISCUSSION: This is the first study to report differences in self-perceived communication competence between adults who do and do not stutter. Results suggest adults who stutter report lower self-perceived communication competence compared to adults who do not stutter. Adults who perceive themselves to have greater communication competence reported less severe overall impact of stuttering, and stuttering frequency did not influence SPCC. Clinical implications for intervention are discussed.

The Communication Benefits of Participation in Camp Dream. Speak. Live.: An Extension and Replication.

School-based guidelines often require that treatment focuses on minimizing or eliminating stuttered speech. The purpose of this study was to examine the benefits of explicit training in communication competencies to children who stutter without targeting stuttered speech. Thirty-seven children (ages 4-16) completed Camp Dream. Speak. Live., an intensive group treatment program which targets the psychosocial needs and communication of children who stutter. Outcome measures included the Overall Assessment of the Speaker's Experience of Stuttering (OASES), the Communication Attitude Test for Preschool and Kindergarten Children Who Stutter (KiddyCAT), and the Patient Reported Measurement Information System (PROMIS) Pediatric Peer Relationships Short Form (PROMIS Peer Relationships) and Parent Proxy Peer Relationships Short Form (PROMIS Parent Proxy). Pre- and posttreatment public presentations were rated on nine core verbal and nonverbal communication competencies by a neutral observer. Similar to previous studies, participants demonstrated significant improvements in communication attitudes (OASES) and perceived ability to establish peer relationships (PROMIS Peer Relationships), particularly school-aged participants (ages 7-16). Participants also demonstrated significant improvement in eight of the nine communication competencies. Findings suggest that, in addition to the psychosocial gains of programs such as Camp Dream. Speak. Live., children who stutter benefit from explicit training in communication skills, and these gains are not dependent on the presence of stuttered speech.

College professors' perceptions of students who stutter and the impact on comfort approaching professors.

PURPOSE: Previous literature has documented that college professors view hypothetical students who stutter more negatively than their fluent peers. The purpose of the present study was to investigate whether individuals who stutter report they experience more negative perceptions in the college classroom, and the impact of those perceptions on their comfort approaching professors. METHODS: Two hundred forty-six adults who do and do not stutter, matched for age, participated in this study. Participants were presented with 16 positive and negative personality traits and asked to rate how strongly they believed their professor viewed them along each trait. All participants were asked whether they felt comfortable approaching their professors to discuss their performance. Adults who stutter were asked additional questions to investigate their college experience more comprehensively. RESULTS: Adults who stutter reported they experienced significantly more negative perceptions from their professors than adults who do not stutter, and were significantly less likely to feel comfortable approaching their professors. These reported negative perceptions, specifically being perceived as less self-assured, predicted comfort approaching professors to receive performance feedback for adults who stutter. Finally, amongst adults who stutter, perception of how they were evaluated compared to their peers was significantly related to comfort approaching professors. CONCLUSIONS: Results support that the negative perceptions towards hypothetical students who stutter reported in previous literature are experienced by individuals who stutter, and that these perceptions drive comfort approaching professors for performative feedback. Results suggest professors may increase students' comfort by clearly outlining equality in evaluation procedures.

Speech-Language Pathologists' Comfort Level With Use of Term "Stuttering" During Evaluations.

Purpose Speech-language pathologists (SLPs) anecdotally report concern that their interactions with a child who stutters, including even the use of the term "stuttering," might contribute to negative affective, behavioral, and cognitive consequences. This study investigated SLPs' comfort in providing a diagnosis of "stuttering" to children's parents/caregivers, as compared to other commonly diagnosed developmental communication disorders. Method One hundred forty-one school-based SLPs participated in this study. Participants were randomly assigned to one of two vignettes detailing an evaluation feedback session. Then, participants rated their level of comfort disclosing diagnostic terms to parents/caregivers. Participants provided rationale for their ratings and answered various questions regarding academic and clinical experiences to identify factors that may have influenced ratings. Results SLPs were significantly less likely to feel comfortable using the term "stuttering" compared to other communication disorders. Thematic responses revealed increased experience with a specific speech-language population was related to higher comfort levels with using its diagnostic term. Additionally, knowing a person who stutters predicted greater comfort levels as compared to other clinical and academic experiences. Conclusions SLPs were significantly less comfortable relaying the diagnosis "stuttering" to families compared to other speech-language diagnoses. Given the potential deleterious effects of avoidance of this term for both parents and children who stutter, future research should explore whether increased exposure to persons who stutter of all ages systematically improves comfort level with the use of this term.

Bimanual task performance: Adults who do and do not stutter.

Research has demonstrated children who stutter score significantly lower than children who do not stutter on the Purdue Pegboard Test. Past data also suggest performance on this task may be associated with stuttering frequency (Choo et al., 2016; Mohammadi et al., 2016). The purpose of this study was to explore whether these performance differences and the relationship to stuttering frequency are present in adults who stutter (AWS). Forty-eight participants (AWS = 24, and AWNS = 24) matched for age, gender, education, and handedness completed all four tasks of the Purdue Pegboard Test. There were no significant between group differences and stuttering frequency did not predict performance. These findings suggest previous differences may only be applicable to subgroups and/or that, with development, the manual tasks unique to the Purdue Pegboard Test may not be sensitive enough to reveal differences.

Exploring the Effectiveness of an Intensive Treatment Program for School-Age Children Who Stutter, Camp Dream. Speak. Live.: A Follow-up Study.

The purpose of this follow-up study was to explore the effectiveness of an intensive treatment program-Camp Dream. Speak. Live.-within older, school-age children who stutter. Twenty-three school-age children who stutter (age range: 7-14 years) attended this week-long intensive therapy program for the first time. Outcome measures included Overall Assessment of the Speaker's Experience of Stuttering and the Patient Reported Outcomes Measurement Information System Pediatric Peer Relationships Form. Findings demonstrate significant improvements in quality of life and communication attitudes can be achieved in a short period of time when increasing fluency is not a target.
