Purpose

This study examined filled pause usage in 5-year-old English-speaking children with a history of late talking who had received intervention, compared to typically developing peers, revealing persistent distributional, temporal, and acoustic differences in filled pause usage despite intervention.

Methods

We analysed spontaneous speech samples from 73 children (36 with a late-talking history and 37 typical) using CHILDES Clinical English Ellis Weismer Corpus, focusing on filled pauses ‘um’ and ‘uh’. Filled pauses were categorised by turn-taking position and inter-pausal units, with frequency and lexical choice (uh-rate, um-rate, um-ratio) examined. Duration differences across conversational stages were also assessed. Acoustic analysis visualised pitch contours, periodic energy, and power representations. Cross-correlation analyses explored their relationships in filled pauses.

Results

The distributional analysis revealed that children with a history of late talking produced more ‘um’ in turn-initial and turn-only positions, whilst typically developing children used more in turn-medial positions. Temporal characteristics showed that children who were previously late talkers exhibited longer ‘um’ durations across all conversational stages and slower speech rates. Acoustic analysis demonstrated that their filled pauses displayed consistently higher pitch values and showed distinct cross-correlation patterns, with delayed coordination between pitch and energy compared to typically developing peers, particularly in ‘um’ production.

Conclusion

Children with a late-talking history show increased turn-initial ‘um’ use, longer durations, elevated pitch, and delayed pitch-energy synchronisation, primarily indicating persistent prosodic and processing difficulties despite receiving language intervention.

目的：本研究考察了接受干预的5岁有晚说话史的英语儿童的填充停顿使用情况，并与正常发育的同龄人进行了比较，揭示了干预后填充停顿使用的持续分布、时间和声学差异。方法：我们使用CHILDES临床英语Ellis Weismer语料库对73名儿童（36名有晚说话史，37名正常）的自发语音样本进行分析，重点关注“um”和“uh”的填充停顿。填空停顿按轮流位置和停顿间单位进行分类，并检查了频率和词汇选择（uh-rate, um-rate, um-ratio）。还评估了不同会话阶段的持续时间差异。声学分析可视化的音高轮廓，周期能量和功率表示。交叉相关分析探讨了它们在填充停顿中的关系。结果：分布分析显示，有晚说话史的儿童在开始转动和只转动体位上使用“嗯”字较多，而正常发育的儿童在中间转动体位上使用“嗯”字较多。时间特征表明，以前晚说话的孩子在所有对话阶段都表现出更长的“嗯”持续时间和更慢的语速。声学分析表明，与典型的开发同伴相比，它们的填充暂停显示出一贯的高音高值，并显示出明显的相互关联模式，特别是在“um”生产中，音高和能量之间的协调延迟。结论：有晚说话史的儿童表现出更多的“嗯”的使用，持续时间更长，音调升高，音调能量同步延迟，主要表明尽管接受了语言干预，但仍存在持续的韵律和加工困难。

Purpose

This study aimed to evaluate the psychometric properties of the Simplified Chinese translation of the Overall Assessment of the Speaker’s Experience of Stuttering–Adult (OASES-A-SC), a comprehensive self-report tool designed to measure the impact of stuttering on adults.

Methods

The OASES-A-SC was administered online to 346 Chinese adults who self-identified as people who stutter. Psychometric analyses included test-retest reliability, internal consistency, item-level analysis, and evaluation of content and construct validity based on participant feedback.

Results

The OASES-A-SC demonstrated excellent test–retest reliability (intraclass correlation coefficients >.92) and high internal consistency (Cronbach’s α =.86–.98). Item-level analysis revealed more ceiling effects and fewer floor effects as compared with the data collected in other countries, reflecting more negative stuttering experiences. Feedback from participants supported the content and construct validity of the instrument, highlighting its cultural relevance and comprehensiveness in capturing the lived experience of adults who stutter in China.

Conclusion

The OASES-A-SC is a reliable and valid tool for assessing the overall experience of stuttering among adults in China. The elevated impact ratings and response patterns of the data suggest a more severe psychosocial burden of stuttering in this population, underlining the need for culturally informed clinical approaches and broader public education efforts in China.

目的：本研究旨在评估《成人口吃者说话体验总体评估》（OASES-A-SC）的简体中文译本的心理测量学特征，OASES-A-SC是一种衡量成人口吃影响的综合自我报告工具。方法：对346名自认为口吃者的中国成年人进行在线问卷调查。心理测量分析包括重测信度、内部一致性、项目水平分析以及基于参与者反馈的内容和结构效度评估。结果：oasas - a - sc具有良好的重测信度（类内相关系数bb0.92）和较高的内部一致性（Cronbach’s α = 0.86 ~ 0.98）。项目层面的分析显示，与其他国家收集的数据相比，天花板效应更多，地板效应更少，反映了更多的负面口吃经历。参与者的反馈支持了该工具的内容和结构效度，强调了其在捕捉中国口吃成年人生活经验方面的文化相关性和全面性。结论：OASES-A-SC是评估中国成人口吃总体经历的可靠有效的工具。这些数据的影响评分和反应模式的提高表明，口吃在这一人群中有更严重的社会心理负担，强调了中国需要有文化背景的临床方法和更广泛的公共教育努力。

Purpose

This study compares the performance of Turkish-speaking school-aged children who stutter (CWS) and their fluent peers (CWNS) in nonword recognition (NW_rec) and nonword repetition (NW_rep) tasks. The effects of syllable length on NW_rec accuracy and NW_rep accuracy, number of attempts, and first-attempt accuracy were examined. NW_rep fluency was assessed only in the CWS group.

Method

Seventeen CWS (6–12 years) and 17 age- and sex-matched CWNS participated. NW_rec required identifying a target nonword from three probes across syllable lengths (2-, 3-, and 4-syllables). NW_rep involved repeating 12 nonwords per syllable set, assessing accuracy, attempts, first-attempt accuracy, and fluency.

Results

Group significantly predicted NW_rec (p = .039), with CWNS outperforming CWS. Age positively affected NW_rec (p = .003) and NW_rep accuracy (p < .001). Syllable length influenced NW_rep accuracy (p < .001), number of attempts (p < .001), and fluency (p = .004). Significant Group × Length interactions were found for number of attempts (p < .001) and first-attempt accuracy (p = .006). Post-hoc comparisons were conducted for these interactions and fluency. Two-syllable items were most fluent, and group differences were most pronounced in the four-syllable condition.

Conclusion

CWNS outperformed CWS in NW_rec. Age influenced NW_rec and NW_rep accuracy. Syllable length did not affect NW_rec but impacted NW_rep: accuracy declined, attempts increased, and first-attempt accuracy and fluency decreased with longer nonwords. Significant interactions emerged for first-attempt accuracy and attempts, with four-syllable items especially challenging for CWS. Findings underscore NW_rep’s phonological–articulatory demands, supporting separate recognition and production assessment.

目的比较说突厥语的口吃学龄儿童（CWS）和流利学龄儿童（CWNS）在非词识别（NWrec）和非词重复（NWrep）任务中的表现。研究了音节长度对词频准确度和词频准确度、尝试次数和首次尝试准确度的影响。仅在CWS组中评估NWrep流畅性。方法17例6 ~ 12岁的CWS和17例年龄、性别匹配的CWS。NWrec需要从跨音节长度（2、3和4音节）的三个探针中识别目标非词。NWrep包括每个音节重复12个非单词，评估准确性、尝试次数、第一次尝试的准确性和流利度。结果组显著预测NWrec （p = ）。039)，其中CWNS表现优于CWS。年龄正影响NWrec （p = .003）和NWrep准确率（p <； .001）。音节长度影响nwrp的准确性（p <； ）。001)，尝试次数(p <； 。001)，流畅性（p = .004）。尝试次数（p <； .001）和首次尝试准确性（p = .006）存在显著的组× 长度交互作用。对这些互动和流畅性进行了事后比较。双音节项目最流利，四音节项目的组间差异最明显。结论在NWrec中，cwns优于CWS。年龄影响NWrec和NWrep的准确性。音节长度不影响NWrec，但会影响NWrep：准确性下降，尝试次数增加，第一次尝试的准确性和流畅性随着非单词的增加而下降。在首次尝试的准确性和尝试次数方面出现了显著的相互作用，对于CWS来说，四音节项目尤其具有挑战性。研究结果强调了NWrep的语音-发音要求，支持单独的识别和生产评估。

Choral speech, defined as speaking in unison with another voice, has long been recognised for improving speech fluency while maintaining speech naturalness for people who stutter (PWS). However, its practical application has been limited by the need for a live second voice. This exploratory study investigated whether choral speech could be used in a simulated presentation setting with two alternative voice sources: participants’ own voice recording and computer-generated voice. The condition using participants’ own recording built on findings that many PWS experience increased fluency when speaking alone; participants therefore recorded their voice on their own, which was later played back through headphones during their presentation. In the computer-generated voice condition, participants synchronised their speech with a text-to-speech (TTS) decoder after uploading the presentation text. Two additional conditions were included for comparison: a baseline reading with no intervention, and a non-speech auditory feedback using white noise. Results showed a substantial decrease in disfluent syllables, with the mean percentage dropping from 10 % at baseline to below 3 % in both choral speech conditions. One participant reduced stuttering from 49 % to 2 %, and shortened reading duration from approximately 19 to 4 min with the TTS decoder, while improving perceived speech naturalness. To the author’s knowledge, these preliminary results are first to suggest that choral speech with a TTS decoder can significantly reduce stuttering in a simulated presentation setting. Further research should investigate its clinical potential to support real-life presentations and reduce public speaking avoidance.

合唱，被定义为与另一个声音齐声说话，长期以来一直被认为可以提高口吃者的语言流畅性，同时保持语言的自然性。然而，它的实际应用一直受到对现场第二声音的需求的限制。本探索性研究探讨了合唱是否可以在模拟演讲环境中使用两种替代声音来源：参与者自己录制的声音和计算机生成的声音。使用参与者自己录音的条件建立在许多PWS经历单独说话时流利程度提高的发现之上；因此，参与者自己录下自己的声音，然后在演讲时通过耳机回放。在计算机生成语音的条件下，参与者在上传演示文本后，将他们的演讲与文本到语音（TTS）解码器同步。另外两种情况用于比较：无干预的基线阅读和使用白噪声的非言语听觉反馈。结果显示，在两种合唱条件下，不流利音节的平均百分比从基线时的10 %下降到3 %以下。一名参与者使用TTS解码器将口吃从49% %减少到2% %，并将阅读时间从大约19分钟缩短到4 分钟，同时提高了感知语音的自然度。据作者所知，这些初步结果首次表明，在模拟演示环境中，使用TTS解码器的合唱演讲可以显著减少口吃。进一步的研究应该调查它的临床潜力，以支持现实生活中的演讲，减少公众演讲回避。

We evaluated the efficacy of Frankini, a 12-month early parent-child intervention that combines online parent counseling with hybrid speech restructuring to reduce stuttering severity and promote fluency-supportive interaction. This retrospective, nonrandomized pilot trial included cases enrolled between September 2019 and November 2023. For analysis, only participants who completed Module 1 (indirect parental training) and Module 2 (the first hybrid speech restructuring module) were included. A total of 51 cases met all inclusion criteria, and 30 of these completed all three modules. To simulate a wait-list-controlled design, eligible participants were divided into early and delayed groups using median split. The early group completed Module 2 nine months after baseline, the delayed group twelve months after baseline. Groups were matched on key characteristics and differed only in the timing of the first direct intervention. Blinded raters assessed stuttering severity. Primary outcomes included the Stuttering Severity Index, parental severity rating, and a 10-item parent report. At 9 months, the early group showed reduced stuttering severity, while the delayed group showed no change (mean difference = −8.33 95 %CI [−12.98, −3.68], p < 0.001, with d = −1.14). By 12 months, both groups improved, and group difference were no longer significant (mean difference = −3.37 95 %CI [−8.23, 1.50], p = 0.168 and d = −0.48). Parental ratings mirrored these outcomes showing consistent improvement after each module. Speech restructuring significantly improved speech fluency and parent counseling enhanced parents' confidence, supporting the value of initiating treatment before age 6; however, follow-up is needed to assess long-term effects.

我们评估了Frankini的有效性，这是一项为期12个月的早期亲子干预，将在线家长咨询与混合语言重组相结合，以减少口吃的严重程度，促进流利性支持互动。这项回顾性、非随机的试点试验纳入了2019年9月至2023年11月期间登记的病例。为了进行分析，只包括完成模块1（间接父母培训）和模块2（第一个混合语音重组模块）的参与者。共有51例病例符合所有纳入标准，其中30例完成了所有三个模块。为了模拟等候名单控制设计，采用中位数分割法将符合条件的参与者分为早期组和延迟组。早期组在基线后9个月完成模块2，延迟组在基线后12个月完成模块2。各组在关键特征上相匹配，仅在第一次直接干预的时间上有所不同。盲法评分者评估口吃的严重程度。主要结果包括口吃严重程度指数、父母严重程度评分和一份包含10项内容的父母报告。9个月时，早期组出现口吃严重程度降低，而延迟组无变化（平均差异= - 8.33 95 %CI [- 12.98, - 3.68], p <； 0.001,d = - 1.14）。12个月后，两组均有所改善，组间差异不再显著（平均差异= - 3.37 95 %CI [- 8.23, 1.50], p = 0.168,d = - 0.48）。家长的评分反映了这些结果，在每个模块之后都显示出持续的改善。言语重组显著提高了言语流畅性，家长咨询增强了家长信心，支持6岁前开始治疗的价值；然而，需要随访来评估长期效果。试验注册：DRKS00034731。

Background

There has been a significant paucity of data on the variability of stuttering severity across the biological rhythms associated with sex steroid hormones. The menstrual cycle, a prominent infradian rhythm, provides a unique and naturalistic environment to investigate the impact of fluctuating sex steroid hormones on the severity of stuttering.

Methods

A withdrawal/reversal A₁B₁C₁A₂B₂C₂ single-subject design was employed, involving multiple daily assessments of stuttering severity across two consecutive menstrual cycles in adult women who stutter. Five adult women with confirmed developmental stuttering, regular menstrual cycles, and verified ovulation participated in the study. Participants self-rated their stuttering severity daily using a 10-point severity rating scale. Data were analyzed through a combination of visual analysis and effect size calculations.

Results

An increase in self-reported stuttering severity was observed during the follicular phase compared to the preceding menstrual phase. Furthermore, stuttering severity decreased during the luteal phase relative to the preceding follicular phase. These patterns were replicated in most participants; however, replication was not uniform, and some individual cycles showed variability.

Conclusion

These findings indicate that the follicular phase is associated with increased self-reported stuttering severity in women who stutter, suggesting the influence of menstrual cycle phases on stuttering dynamics.

背景：在与性类固醇激素相关的生物节律中，口吃严重程度的可变性数据非常缺乏。月经周期是一个重要的昼夜节律，为研究性类固醇激素波动对口吃严重程度的影响提供了一个独特而自然的环境。方法采用A₁B₁C₁A₂B₂C₂单受试者设计，对成年口吃女性连续两个月经周期的口吃严重程度进行多次每日评估。5名成年女性被确诊为发育性口吃，月经周期正常，并确认排卵。参与者每天使用10分制的口吃严重程度量表对自己的口吃严重程度进行自我评估。通过可视化分析和效应量计算相结合的方法分析数据。结果在卵泡期与前月经期相比，自我报告的口吃严重程度有所增加。此外，相对于前卵泡期，在黄体期口吃严重程度降低。这些模式在大多数参与者身上得到了重复；然而，复制并不均匀，个别周期表现出可变性。结论这些研究结果表明，卵泡期与口吃女性自述的口吃严重程度增加有关，提示月经周期对口吃动态的影响。

Purpose

During adolescence, individuals experience rapid physical, cognitive, and psychosocial changes. This transition may raise additional challenges for an adolescent who stutters. Although previous research has examined the experiences of adolescents who stutter, their preferences remain unstudied, particularly in non-Western countries. This qualitative study explored how Saudi Arabian adolescents who stutter perceive their stuttering and its management, and their preferences for support.

Method

To gain preliminary insight into this unstudied area of research, eight participants, aged 13–17 years and 11 months, diagnosed with developmental stuttering by a qualified speech-language pathologist, and were Saudi Arabian citizens living in Saudi Arabia, were recruited through administrative staff at two clinics. Reflexive thematic analysis was used to identify themes and sub-themes.

Results

Data revealed four main themes: Stuttering and my emotions; Stuttering and my environment; Therapy is a journey; and Listen to my voice. Although some participants reported feeling positive about their stuttering, all participants had experienced negative emotions due to stuttering. Furthermore, others' awareness and reactions to stuttering played a significant role in shaping participants’ communication experiences. The results emphasised that stuttering therapy is a dynamic, individualized journey. Participants desired more than speech therapy; they also sought independence, privacy, and support from their social environment.

Conclusion

Results highlighted that Saudi Arabian adolescents who stutter want to be heard and supported by people in their environment. Key stakeholders, including speech-language pathologists, teachers, caregivers, adolescents, and professional bodies, could utilise this information to develop tailored evidence-based interventions and provide individualised support for adolescents who stutter.

目的在青春期，个体经历快速的身体、认知和心理社会变化。这种转变可能会给口吃的青少年带来额外的挑战。尽管之前的研究已经调查了口吃青少年的经历，但他们的偏好仍然没有得到研究，特别是在非西方国家。这项定性研究探讨了沙特阿拉伯的口吃青少年如何看待他们的口吃及其管理，以及他们对支持的偏好。方法为了初步了解这一未被研究的研究领域，通过两家诊所的管理人员招募了8名年龄在13-17岁零11个月的参与者，他们都是居住在沙特阿拉伯的沙特阿拉伯公民，由一名合格的语言病理学家诊断为发育性口吃。反身性主题分析用于识别主题和副主题。结果数据揭示了四个主要主题：口吃和我的情绪；口吃和我的环境；治疗是一个旅程；听我的声音。尽管一些参与者对自己的口吃感到积极，但所有参与者都因口吃而经历了负面情绪。此外，其他人对口吃的认识和反应在塑造参与者的沟通体验中起着重要作用。研究结果强调，口吃治疗是一个动态的、个性化的过程。参与者想要的不仅仅是语言治疗；他们还寻求独立、隐私和社会环境的支持。结论研究结果表明，沙特阿拉伯的口吃青少年希望在他们的环境中得到他人的倾听和支持。主要利益相关者，包括语言病理学家、教师、护理人员、青少年和专业机构，可以利用这些信息制定量身定制的循证干预措施，并为口吃青少年提供个性化支持。

Developmental stuttering is a disorder with a high degree of heterogeneity, both behaviourally and neurologically. Research from different perspectives of stuttering indicates that sex is a potentially differentiating factor. In our study we explored if sex is related to variability of grey matter volume (GMV) patterns in adults with developmental stuttering. We used MRI to collect data on GMV from 24 righthanded adults who stutter (9 women and 15 men) and 29 righthanded fluent controls (10 women and 19 men). We analysed the following for 24 ROIs of the language system: 1) whole-group differences between the stuttering group and controls and 2) interaction between group (adults with stuttering versus controls) and sex. Our explorative results indicate that differences in grey matter volume between adults with stuttering and fluent adults are sex-specific for several areas involved in speech and language processing. We found an interaction between group and sex for the right BA45. The interaction indicates that men who stutter have larger GMV in this area compared to fluent men while women who stutter have smaller GMV compared to fluent women. Further, we found indications of sex-specific patterns in other areas of the bilateral inferior frontal cortex, but not the BA44, as well as in the cerebellum and the striatum.

发展性口吃是一种在行为上和神经上都具有高度异质性的疾病。从不同角度对口吃进行的研究表明，性别是一个潜在的区分因素。在我们的研究中，我们探讨了性别是否与成人发育性口吃的灰质体积（GMV）模式的可变性有关。我们使用MRI收集了24名右撇子口吃成人（9名女性和15名男性）和29名右撇子流利对照（10名女性和19名男性）的GMV数据。我们对24个语言系统的roi进行了以下分析：1)口吃组和对照组之间的整体差异；2)口吃组（口吃成人与对照组）和性别之间的互动。我们的探索性结果表明，口吃的成年人和流利的成年人之间的灰质体积差异在涉及语音和语言处理的几个区域具有性别特异性。我们发现，对于正确的BA45，群体和性别之间存在相互作用。相互作用表明，口吃的男性在这一区域的GMV比流利的男性大，而口吃的女性在这一区域的GMV比流利的女性小。此外，我们在双侧额叶下皮层的其他区域发现了性别特异性模式的迹象，但在BA44以及小脑和纹状体中没有。

Stuttering is a variable speech disorder whose brain mechanisms remain unknown. Sensorimotor brain circuits, critical in motor-speech control, including the prediction and monitoring of speech consequences, have been linked to the disorder. Despite considerable advances, it remains unclear whether auditory neural circuits relate to stuttering severity, and whether interventions to persons who stutter can induce underlying brain changes. We employed electroencephalography (EEG), in a group of persons who stutter (PWS), in combination with auditory probes to tap onto the relevance of auditory cortical regions in stuttering severity. Participants produced flexible speech (i.e., describing pictures) and non-flexible speech (i.e., reading syllables), following an auditory cue. More pronounced P200 auditory evoked potentials in response to the auditory cues were observed in participants with more severe stuttering, mainly in the picture task. Interestingly, while speech therapy intervention led to a reduction (albeit non-significant) of the P200 potential, this reduction was marginally correlated to speech fluency improvements. Moreover, EEG response patterns discriminative of cue tone frequency (400 Hz versus 800 Hz) were also predictive of stuttering severity, suggesting the involvement of fine-grained auditory cortical processing in speech preparation and stuttering. Overall, this study confirms a relationship between auditory processing of external sounds and the mechanisms of stuttering during the preparation to speak and highlights the advantage of a picture description task to investigate the relationship between auditory evoked potentials and stuttering severity under relatively ecological conditions.

口吃是一种可变的语言障碍，其大脑机制尚不清楚。感觉运动脑回路是运动-语言控制的关键，包括对语言后果的预测和监测，与这种疾病有关。尽管取得了相当大的进步，但听觉神经回路是否与口吃的严重程度有关，以及对口吃者的干预是否会引起潜在的大脑变化，仍不清楚。我们采用脑电图（EEG），在一组口吃（PWS）的人，结合听觉探针来挖掘听觉皮层区域在口吃严重程度的相关性。参与者根据听觉提示发出灵活的语言（如描述图片）和非灵活的语言（如阅读音节）。重度口吃者的P200听觉诱发电位对听觉线索的反应更为明显，主要表现在图片任务中。有趣的是，虽然言语治疗干预导致P200电位的降低（尽管不显著），但这种降低与语言流畅性的提高有轻微的相关性。此外，区分提示音频率（400 Hz vs 800 Hz）的脑电图反应模式也能预测口吃的严重程度，这表明细粒度听觉皮层加工参与了言语准备和口吃。综上所述，本研究证实了外部声音的听觉加工与言语准备过程中口吃的机制之间的关系，并强调了在相对生态条件下，使用图片描述任务来研究听觉诱发电位与口吃严重程度之间的关系的优势。

Purpose

The purpose of this study was to investigate whether self-rated covert stuttering (i.e., the extent of being able to keep stuttering hidden from others) was associated with anxiety, quality of life, social role satisfaction, speech usage, and salience of stuttering among adults who stutter.

Methods

A sample of 316 adults who stutter was asked about the extent to which they believed they were successful in concealing their stuttering so that others did not know that they stuttered. The sample was divided into two groups, one comprised of people who believed they were more often than not overtly stuttering, and those who believed they were more covert. Groups were compared on variables of anxiety, quality of life, social role satisfaction, speech usage, and salience of stuttering, taking into account demographic and speech-related variables.

Results

There were significant correlations between level of self-rated covertness and all dependent variables. The group that reported being more covert reported significantly higher levels of stuttering salience, and significantly lower levels of quality of life, social role satisfaction, and speech usage compared to the less covert group, after taking into account demographic variables.

Conclusion

Focusing on stuttering visibility in therapy or research, without taking covert stuttering into account, may not optimize outcomes important psychosocial and communicative factors important to people who stutter. Taking into account the extent to which a person who stutters tries to hide their stuttering in assessment and treatment may help improve psychosocial and communicative outcomes, regardless of their physical speech disruption severity.

目的本研究的目的是调查自我评定的隐蔽性口吃（即能够对他人隐瞒口吃的程度）是否与口吃成人的焦虑、生活质量、社会角色满意度、语言使用和口吃的显著性有关。方法对316名口吃的成年人进行抽样调查，询问他们认为自己在多大程度上能够成功地隐藏自己的口吃，使别人不知道自己口吃。这些样本被分为两组，一组认为自己经常明显口吃，另一组认为自己更隐蔽。在考虑人口统计学和语言相关变量的情况下，对各组进行焦虑、生活质量、社会角色满意度、语言使用和口吃显著性等变量的比较。结果自评隐蔽性水平与各因变量均有显著相关。考虑到人口统计变量后，报告更隐蔽的小组报告的口吃显著更高，而生活质量、社会角色满意度和语言使用水平明显低于不那么隐蔽的小组。结论在治疗或研究中关注口吃的可见性，而不考虑隐性口吃，可能无法优化结果，这是对口吃者重要的重要社会心理和交际因素。考虑到口吃者在评估和治疗中试图隐藏口吃的程度，可能有助于改善社会心理和交流结果，而不管他们的肢体语言障碍的严重程度如何。
