The recovery rate of early stuttering

A prospective 14-year follow-up study of the persistence and recovery of stuttering

PURPOSE

To document the trajectory of early childhood stuttering longitudinally for 14. years with a consideration on the features of overt and covert stuttering related to recovery status.

METHOD

Thirty-eight participants were observed longitudinally at three different time points: early childhood (Occasion 1), middle childhood (Occasion 2), and late adolescence (Occasion 3). Data collection involved speech samples and reports of stuttering experiences. Recovery on Occasion 3 was estimated through analysis of speech samples, parent and expert judgments, and self- judgement. Two categories of persistence were used: persistent-subjective (no observable stuttering) and persistent-objective (observable stuttering).

RESULTS

The recovery rate was 65.6%. The majority of the participants showed minimal disfluent speech with 88% showing less than 1% syllables stuttered and 97% showing less than 3% syllables stuttered in the collected speech samples. All participants classified as persistent reported covert symptoms of stuttering. No relapses in recovery were observed between Occasion 2 and Occasion 3. Late recovery was only observed for those classified as persistent-subjective on Occasion 2. About 64% of the participants showing observable stuttering (persistent-objective) on Occasion 2 showed no observable stuttering (persistent-subjective) on Occasion 3.

CONCLUSIONS

Children continue to recover from early childhood stuttering as they age.The inclusion of self-reports adds to the understanding of recovery especially concerning the covert stuttering behaviours. The presence of overt symptoms of stuttering in the speech samples of children aged 7 to 13 years seems to be associated with the likelihood of late recovery of stuttering.

Stuttering as a spectrum disorder: A hypothesis

Childhood-onset fluency disorder, commonly referred to as stuttering, affects over 70 million adults worldwide. While stuttering predominantly initiates during childhood and is more prevalent in males, it presents consistent symptoms during conversational speech. Despite these common clinical manifestations, evidence suggests that stuttering, may arise from different etiologies, emphasizing the need for personalized therapy approaches. Current research models often regard the stuttering population as a singular, homogenous group, potentially overlooking the inherent heterogeneity. This perspective consolidates both historical and recent observations to emphasize that stuttering is a heterogeneous condition with diverse causes. As such, it is crucial that both therapeutic research and clinical practices consider the potential for varied etiologies leading to stuttering. Recognizing stuttering as a spectrum disorder embraces its inherent variability, allowing for a more nuanced categorization of individuals based on the underlying causes. This perspective aligns with the principles of precision medicine, advocating for tailored treatments for distinct subgroups of people who stutter, ultimately leading to personalized therapeutic approaches.

Fostering Positive Stuttering Identities Using Stutter-Affirming Therapy

PURPOSE

School-age children and adolescents frequently have difficulty developing positive identities around their stuttering. Many students experience both physical and social consequences from stuttering. The great lengths that speakers go to try to hide their stuttering and to speak fluently increase their difficulty. As long as school-age children who stutter try to identify as fluent speakers, they will have difficulty lessening the negative impact of stuttering on their lives. Fortunately, many people who stutter also report positive stuttering experiences. Speech-language pathologists can use these positive experiences to help school-age children grow more comfortable with stuttering. They can also help school-age children reduce some of the speaking effort and social stigma that leads them to try to conceal their stuttering in the first place. To accomplish both these goals, I propose a stutter-affirming therapy.

METHOD

This clinical focus article summarizes previous research about identity development in stuttering. I discuss a therapy approach I call stutter-affirming therapy. In elucidating this approach, I discuss practical ways that speech-language pathologists can use to help school-age children develop positive stuttering identities through easier speaking and stuttering. I ground these examples in a case study of a 12-year-old boy who stutters.

DISCUSSION

stutter-affirming therapy focuses on conditioning the speaker's reaction to stuttering in ways that move toward and embrace stuttering (stutterphilic reactions) rather than in ways that move away from and reject stuttering (stutterphobic reactions). Speech-language pathologists can help school-age children who stutter foster positive stuttering identities using the three priorities of stutter-affirming therapy. First, reject fluency by reducing stutterphobic and increasing stutterphilic reactions to stuttering. Second, value stuttering by discovering what speakers gain from it. Third, create an environment in which it is easier to stutter through education, advocacy, disclosure, and voluntary stuttering.

Uncertainty and Perceived Control as Predictors of Communicative Participation and Mental Health in Adults Who Stutter

PURPOSE

This study examined the role of uncertainty and perceived control in predicting the communicative participation and mental health of adults who stutter.

METHOD

Two hundred sixty-nine adults who stutter completed measures of uncertainty about stuttering, perceived control of stuttering, communicative participation, and global mental health. In addition, participants self-reported on a variety of demographic and speech-related measures. Correlational analyses and hierarchical regression were performed to determine associations between variables of interest.

RESULTS

Uncertainty accounted for significant variance in communicative participation and global mental health after statistically controlling for the effects of demographic and speech-related variables. Perceived control accounted for significant variance in communicative participation over and above what was accounted for by demographic variables, speech-related variables, and uncertainty.

CONCLUSIONS

The findings suggest that uncertainty about stuttering and perceived control of stuttering should be accounted for during assessment and intervention with adults who stutter. Interventions that specifically target uncertainty and perceived control may be useful in improving therapeutic outcomes for individuals who stutter.

Predicting Persistent Developmental Stuttering Using a Cumulative Risk Approach

PURPOSE

The purpose of this study was to explore how well a cumulative risk approach, based on empirically supported predictive factors, predicts whether a young child who stutters is likely to develop persistent developmental stuttering. In a cumulative risk approach, the number of predictive factors indicating a child is at risk to develop persistent stuttering is evaluated, and a greater number of indicators of risk are hypothesized to confer greater risk of persistent stuttering.

METHOD

We combined extant data on 3- to 5-year-old children who stutter from two longitudinal studies to identify cutoff values for continuous predictive factors (e.g., speech and language skills, age at onset, time since onset, stuttering frequency) and, in combination with binary predictors (e.g., sex, family history of stuttering), used all-subsets regression and receiver operating characteristic curves to compare the predictive validity of different combinations of 10 risk factors. The optimal combination of predictive factors and the odds of a child developing persistent stuttering based on an increasing number of factors were calculated.

RESULTS

Based on 67 children who stutter (i.e., 44 persisting and 23 recovered) with relatively strong speech-language skills, the predictive factor model that yielded the best predictive validity was based on time since onset (≥ 19 months), speech sound skills (≤ 115 standard score), expressive language skills (≤ 106 standard score), and stuttering severity (≥ 17 Stuttering Severity Instrument total score). When the presence of at least two predictive factors was used to confer elevated risk to develop persistent stuttering, the model yielded 93% sensitivity and 65% specificity. As a child presented with a greater number of these four risk factors, the odds for persistent stuttering increased.

CONCLUSIONS

Findings support the use of a cumulative risk approach and the predictive utility of assessing multiple domains when evaluating a child's risk of developing persistent stuttering. Clinical implications and future directions are discussed.

Relationship between social anxiety and coping profile in adults who stutter

INTRODUCTION

Stuttering is a condition that can be severely disabling in the workplace and socially. Although many stuttering cases resolve, some adults who stutter (AWS) continue to be affected not only by dysfluent speech, but also by other social and psychological conditions that may develop as a result of stuttering. The aim of the present study was to determine the relationship between severity of stuttering, severity of social anxiety, and coping profile.

METHODS

We objectively assessed adults who stutter (n = 44; mean age = 27.5 years) and age-matched non-stuttering control subjects on four variables: stuttering frequency, communication attitude, social anxiety, and coping profile. Stuttering frequency was calculated as the percentage stuttered morae in the Kitsuon-kensa-ho test. All subjects were assessed on the Japanese versions of the Modified Erickson's Communication Attitude Scale (S-24-J), Liebowitz Social Anxiety Scale (LSAS-J), and the Brief Scale for Coping Profile (BSCP).

RESULTS

Compared to the non-stuttering group, the stuttering group had a higher average score on the S-24-J and LSAS-J, and tended to "avoid and suppress" instead of "seek help for resolution" on the BSCP. Comparison of individual stutterers' S-24-J scores whose LSAS-J scores were above or below the LSAS-J cutoff score revealed that their the S-24-J scores tended to be higher. Also, BSCP participants tended to engage in "proactive resolution" and "emotional venting involving others," not "seeking help for resolution." The stuttering group (vs. the non-stuttering group) and the high social-anxiety group (vs. the low social-anxiety group) adopted non-adaptive coping strategies.

CONCLUSIONS

This suggests that the coping profile of AWS may contribute to the cycle of social anxiety and stuttering to a greater or lesser extent. Thus, therapy that reduces anxiety and helps AWS to adopt more adaptive coping strategies may improve stuttering.

Speech-Language Pathologist Perspectives of the Implementation of Telepractice-Delivered Stuttering Treatment for School-Age Children

PURPOSE

The impact of stuttering can be significant, and effective treatment is critical. Despite evidence supporting direct treatment approaches for school-age children who stutter, a complex set of barriers can prevent access at school. One potential solution is telepractice. To date, however, there is no published evidence regarding the use of telepractice to deliver the Lidcombe Program within a school setting.

METHOD

In this pilot study, a telepractice service was established and the perspectives of the five treating speech-language pathologists (SLPs) were evaluated before, during, and after the trial through focus groups and recorded telesupervision sessions.

RESULTS

An inductive and reflexive thematic analysis identified four main themes: (a) Understanding and managing technology is critical; (b) logistical considerations can be time-consuming and challenging; (c) preparation and support are essential; and (d) family engagement, acceptance, and independence with telepractice services can be facilitated by external support and coaching. Initially, the SLPs shared feelings of uncertainty, fear, and apprehension. Yet, despite this concern, the SLPs ultimately reported that telepractice can play an important role in their service.

CONCLUSIONS

In order to maximize the potential value of telepractice, SLPs require training and support to (a) manage the technology and troubleshoot problems that invariably arise, (b) have the opportunity to watch demonstrations of the technology, and (c) clearly explain the roles, responsibilities, and expectations of the parent engaging in treatment. These findings have particular relevance now, as schools and support services navigate a COVID-safe delivery model for the indefinite future.

The Association between Difficulties with Speech Fluency and Language Skills in a National Age Cohort of Children with Down Syndrome

The present study (a) addressed difficulties in speech fluency in children with Down syndrome and typically developing children at a similar non-verbal level and (b) examined the association between difficulties with speech fluency and language skills in children with Down syndrome. Data from a cross-sectional parent survey that included questions about children's difficulties with speech fluency, as well as clinical tests from a national age cohort of 43 six-year-olds with Down syndrome and 57 young typically developing children, were collected. Fisher's exact test, Student's t-test, linear regression, and density ellipse scatter plots were used for analysis. There was a significantly higher occurrence of parent-reported difficulties with speech fluency in the children with Down syndrome. Higher language scores were significantly associated with a lower degree of difficulties; this association was strongest for vocabulary and phonological skills. Although difficulties with speech fluency were not reported for all children with Down syndrome, a substantially higher occurrence of such difficulties was reported compared to that for typically developing children. The significant association between difficulties with speech fluency and the level of language functioning suggests that speech fluency and language skills should be taken into consideration when planning treatment for children with Down syndrome.

Verbal Contingencies in the Lidcombe Program: A Noninferiority Trial

Purpose The Lidcombe Program is an efficacious and effective intervention for early stuttering. The treatment is based on parent verbal response contingent stimulation procedures, which are assumed to be responsible for treatment effect. The present trial tested this assumption. Method The design was a parallel, open plan, noninferiority randomized controlled trial. In the experimental arm, the five Lidcombe Program verbal contingencies were removed from parent instruction. The primary outcome was beyond-clinic percentage syllables stuttered at 18-month follow-up. Seventy-four children and their parents were randomized to one of the two treatment arms. Results Findings of noninferiority were inconclusive for the primary outcome of stuttering severity, based on a margin of 1.0 percentage syllables stuttered. Conclusions The inconclusive finding of noninferiority means it is possible that verbal contingencies make some contribution to the Lidcombe Program treatment effect. However, considering all primary and secondary outcomes, an overriding impression from the trial is a similarity of outcomes between the control and experimental arms. The clinical applications of the trial are discussed, along with further research that is needed.

Recovery and Relapse: Perspectives From Adults Who Stutter

Purpose Recovery and relapse relating to stuttering are often defined in terms of the presence or absence of certain types of speech disfluencies as observed by clinicians and researchers. However, it is well documented that the experience of the overall stuttering condition involves more than just the production of stuttered speech disfluencies. This study sought to identify what recovery and relapse mean to people who stutter based on their own unique experiences to account for both the stuttering behaviors and the broader adverse impact of the condition. Method In this study, 228 adults who stutter participated in a mixed-methods exploration of the terms "recovery" and "relapse." Participants categorized themselves on whether they considered themselves to have recovered or experienced relapse. Data were analyzed thematically through the lens of the speaker self-categorizations to determine how adults who stutter define recovery and relapse regarding stuttering. Results Results indicate that, to adults who stutter, recovery from stuttering is associated with increases in positive affective/emotional, behavioral, and cognitive reactions to the condition and simultaneous decreases in associated negative constructs. These group-level definitions did not change as a function of whether respondents reported that they had experienced recovery or relapse themselves. Discussion Recovery or relapse from stuttering behaviors can occur independently from recovery or relapse from the broader adverse impact related to the condition, suggesting that researchers and clinicians should consider recovery and relapse as involving more than just a reduction or an increase in observable behaviors. These findings support recent research evidence further specifying the many individual phenotypes of stuttering, in that pathways to recovery and relapse can be experienced in different ways for people with different stuttering phenotype profiles.
