Background Few studies have been carried out concerning the relation between stuttering behaviors and language pragmatics in children who stutter (CWS). The correlation between stuttering severity and pragmatic development in CWS is scarce in the literature so far.
Aim This research aimed to study the relationship between stuttering severity and pragmatic language development in the Egyptian Arabic-speaking CWS.
Patients and methods This study is an analytical cross-sectional study carried out at the Phoniatrics Clinics of El-Demerdash Hospital (Ain Shams University) and El-Zahraa Hospital (Al Azhar University). A total of 60 Egyptian CWS in the age range between 4 years 1 day and 9 years 11 months 31 days were selected conveniently based on inclusion and exclusion criteria. Selected children underwent the Ain Shams assessment protocol for fluency disorders, including assessment of stuttering severity by Bloodstein (BLS) classification and the Stuttering Severity Instrument for Children and Adults − Arabic version (ASSI). The standardized Egyptian Arabic Pragmatic Language Test has been used to assess the pragmatic language development.
Pearson’s correlation coefficient has been used to correlate the total pragmatic language age and degree of stuttering severity by BLS classification and the ASSI.
Results Upon application of the Egyptian Arabic Pragmatic Language Test, all the participating children had no pragmatic language delay. They had scores either at and/or above their fifth percentiles in all the test items except in the paralinguistic aspect. There was no statistically significant correlation between grades of BLS classification or ASSI and the total pragmatic language age.
Conclusion CWS had no pragmatic language delay except in the paralinguistic aspects.

| Introduction|| |
Stuttering is a disorder affecting fluency of speech through interruption of the flow of speech by certain obstacles: repetitions, prolongations, blocks, interjection, and others. A negative reaction of the speaker to these interruptions in the form of avoidance and struggle together with the negative reaction of the listener cause variable degrees of dysprosody with resultant poor intelligibility of speech .
Although a variety of theories have been proposed to explain its etiology, the exact cause of stuttering is still unknown . The relation between stuttering and language is intuitive in young children. Several scholars have noted that stuttering onset, typically between ages 2 and 4, coincides with the critical period of accelerated expansion in children’s expressive and receptive language . The possible stuttering–language link has become a focus of scientific interest, reflected in several stuttering models with psycholinguistic viewpoints. Among these are the Demands–Capacity Model , the Covert–Repair Hypothesis , the Trade-Off Hypothesis , and the Cognitive Interference Model .
Investigators have focused their studies on five distinct linguistic variables: (a) phonological aspects, (b) loci of stuttering, (c) language complexity, (d) pragmatics, and (e) language skills. Research concerned with the phonological aspects has provided evidence that stuttering increases as a function of language complexity ,.
A simple but functional definition of pragmatics is that it is the language use or the set of sociolinguistic rules one knows and uses in determining who says what to whom, how, why, when, and in what situation .
Swiney  indicated, based on his clinical observations of children and young adults who stutter, that both often have situational speaking fears associated with their fluency disorder in addition to pragmatic weakness. This coincides with reports by Blood and Seider  who indicated that 68% of the children who stutter (CWS) have at least one concomitant disorder.
Therefore, pragmatics have a bidirectional role in CWS. These children often show pragmatic language disorders that either influence or complicate their speaking fears. The demands and capacities model, as explained by Starkweather , indicates that dysfluency can occur when speech demands exceed a child’s motor, linguistic, and/or emotional capacities. Consequently, it is easy to understand how the linguistic and cognitive demands of dealing with the spontaneity of pragmatics, the most complex of language tasks, can increase dysfluency in CWS .
Weiss  reported that CWS produce much more dysfluent utterances in unstructured versus structured conversations, and neither partner nor number of conversation participants results in a significant difference in the number of dysfluent utterances produced. CWS were more likely to produce dysfluencies as the length and complexity of their utterance increased. Accordingly, increasing a client’s pragmatic skills improves narratives and expository discourse and, thus, all fluency therapy eventually covers these types of conversational interactions.
Among pragmatic skills that affect conversation is eye contact. Eye contact is a form of nonverbal communication and has a large influence on social behavior. Many stutterers as reported by Fraser  do not look people squarely in the eye when they talk to them particularly when they are stuttering or anticipating a block. By doing so, their shame or embarrassment feelings about their difficulties tend to increase.
Shaheen et al.  declared that CWS have a significantly lower total language score with a significant deficiency in pragmatic skills compared with fluent children.
Although many studies concerned with the relation between stuttering behaviors and language pragmatics in CWS exist, absence of enough information about the relation between stuttering severity and pragmatic language development, especially in Arabic-speaking societies, was the motive to design this study.
This research aimed to study the relationship between stuttering severity and pragmatic language development in the Egyptian Arabic-speaking CWS to uncover part of the mysterious association between language and stuttering.
| Patients and methods|| |
This study is an analytical cross-sectional study carried out at the Phoniatrics Unit of El-Demerdash Hospital (Ain Shams University) and El-Zahraa Hospital (Al Azhar University), between October 2016 and May 2017. A total of 60 Egyptian CWS in the age range between 4 years 1 month 1 day and 9 years 12 months 31 days were included and divided into three age groups as follows:
- Group I: 4 years 1 month 1 day to 5 years 12 months 31 days.
- Group II: 6 years 1 month 1 day to 7 years 12 months 31 days.
- Group III: 8 years 1 month 1 day to 9 years 12 months 31 days.
A convenience sample has been used to select the participants based on the following inclusion and exclusion criteria.
- CWS more than 6 months’ duration.
- Children with average intelligence quotient (IQ).
Children with delayed language development and or any speech or voice disorder that might affect speech intelligibility were excluded.
All parents of the participating children provided informed consent and the study protocol was approved by the Ain Shams Institute’s committee of human research.
The Ain Shams assessment protocol of fluency disorders  has been applied to all participating children, with assessment of pragmatic language carried out as follows:
Elementary diagnostic procedures
- Parents and child’s interview: complete assessment of the personal, family, and developmental histories, including information about:
- Ages at which the family has noticed stuttering symptoms and ages at which the child has noticed it and started suffering from it.
- What increases or decreases stuttering?
- Any especially difficult situations, sounds, or words, avoidance and replacement of difficult words with synonyms.
- Whether the child is aware and frustrated by his or her dysfluencies and to what extent.
- Auditory perceptual assessment: describes the pattern of dysfluencies: repetition of a phrase, word, or syllable, prolongations, blocks, interjections, and word or sound avoidance.
- Visual perceptual assessment: observe the child for any associated involuntary movements, eye contact, associated reactions to the speaking situation, avoiding certain expressions, or a certain overt emotion.
- Oral–aural tract examination.
Clinical diagnostic aids
Documenting the voice and speech using an audiorecording of a speech sample.
Additional instrumental measures
- Stanford Binet Intelligence Scale (5th ed.) : to assess the IQ.
- Assessment of the stuttering severity using:
- Bloodstein classification (BLS) : it depends on the child’s awareness, sensitization, and avoidance and has four grades: BLS I, unaware; BLS II, aware, but not annoyed, no avoidance; BLS III, aware, annoyed, sensitized, partial avoidance, no struggle; and BLS IV, fully aware and suffering.
- Stuttering Severity Instrument for Children and Adults − Arabic version (ASSI) : it gives a single numerical representation of severity index (Stuttering Severity Instrument) from 0 to 45 that includes the sum of scores of three parameters (frequency of stuttered words per 100 words, duration of the three longest blocks, and observable physical concomitants). It uses the following grading system: 0–19, very mild stuttering; 20–22, mild stuttering; 23–30, moderate stuttering; 31–33, severe stuttering; 34–45, very severe stuttering.
- Assessment of the child’s language using subjective language test to exclude any language delay.
- Assessment of language pragmatics using the standardized Egyptian Arabic Pragmatic Language Test (EAPLT) : it assesses the nonverbal, paralinguistic, and verbal skills. Depending on the child’s chronological age, the 5th and 95th percentile ranks of the child’s total score and his or her scores in each subset of the EAPLT were calculated. The fifth percentile rank indicates that the child developed the skill, whereas the 95th percentile rank implies that the child mastered it. Scores below the fifth percentile rank indicated pragmatic language delay.
Data management and analysis
The data were collected and introduced to a personal computer (Released 2011; IBM Corp., Armonk, New York, USA), and were analyzed using the program IBM statistical package for the social sciences (SPSS) for Windows version 20.0. (IBM Corp.). Data analysis was performed according to the type of data obtained for each variable.
The statistical tests used in this study are a one-way analysis of variance, the χ2-test, and Pearson’s correlation coefficient test.
| Results|| |
This study was conducted on 60 Egyptian CWS with no history of delayed language development or any other speech or voice disorders that might affect speech intelligibility. The mean age of the participating children was 8.06±1.48 years, with male participants representing 88.3%. All the participating patients were right-handed, with a mean IQ of 92.02±2.68. Of the participating patients, 43.3% had a family history of stuttering ([Table 1]).
The medical history revealed that the mean age of onset of stuttering symptoms was 4.57±0.95 years, whereas the mean age at which the family noticed the stuttering symptoms was 5.54±1.2 years, whereas the mean age at which the child started to notice the stuttering symptoms was 6.59±1.15 years and the mean age at which the child started to suffer was 7.34±1.146 years ([Table 2]).

Upon detailed analysis of the stuttering symptoms, 40% of the participated children linked stuttering symptoms to specific situations. Overall, 30% of the participating children linked stuttering symptoms to school situations. Only 5% of the participating children correlated the appearance or the increase of their stuttering with a specific spoken sound and/or word ([Table 3]).

The auditory perceptual assessment of the speech of the participating children revealed that 65% of the automatic speech was free from any dysfluency, whereas all of them have affected spontaneous speech. Word repetitions constituted the most common core behavior. Intraphonemic disruption and blocks were the second most common speech behaviors noticed in 63.3 and 48.3%, respectively, followed by interjections and prolongations with percentages of 20 and 15%, respectively ([Table 4]).

BLS classification and the ASSI were used to evaluate the severity of stuttering symptoms. According to the BLS classification, 70% of children were BLS III with moderate degree of stuttering, whereas 25% of them were Bloodstein (BLS) II (mild degree stuttering), and only 5% were BLS IV (severe degree of stuttering) ([Table 5]).

After exclusion of any language delay, the EAPLT was applied. All the participating children showed no pragmatic language delay. In all, 93.3% of children have a total score above their fifth percentile and 6.7% children have total score at their fifth percentile. Analysis of the scores of the EAPLT subsets showed that 16 (26.7%) children have scores below their fifth percentile in the paralinguistic aspect ([Table 7]).

| Discussion|| |
The literature is deficient in answering questions about the correlation between stuttering severity and pragmatic language development. This could be due to many conflicts regarding measuring stuttering severity and pragmatic development, especially in the Arabic-speaking Societies.
Sheehan  linked stuttering to an iceberg, with visible overt symptoms above the water representing the dysfluent speech, and the predominant aspects of the disorder representing the secondary behaviors that remain invisible. These secondary behaviors include physical involuntary movements, interjections, together with feelings and thoughts of frustration, anxiety, anger, and expectation of difficulty in talking, which lead to avoidance behavior. These secondary behaviors impair the ability to communicate effectively and aggravate problems that result from primary behaviors .
Because stuttering shows task-dependent severity, the overt symptoms of stuttering have been assessed during different speech tasks including reading, reciting, and spontaneous speech . The avoidance behavior and the child’s feelings and thoughts were evaluated throughout the parents’ and the child’s interview. Stuttering severity was graded by both qualitative (BLS classification) and quantitative (ASSI) measures of stuttering severity.
ASSI is an objective, valid, and reliable measure that offers a holistic way of evaluating stuttering severity and suits the Arabic environment socially, linguistically, and culturally .
The EAPLT  used to assess the pragmatic development is a valid and reliable test that provides reliable information about the language pragmatics of Arabic-speaking Egyptian children from 2 years 1 month 1 day to 9 years 12 months 31 days compared with the protocol of pragmatic assessment designed in Cairo University of Egypt that focuses only on preverbal communication, conversation, and narrative skills , the EAPLT is a holistic test for assessing the three domains of pragmatic language: skills, functions, and factors . Moreover, Alduais et al.  designed an Arabic version of Test of Pragmatic Language-2, which needs changes to suit the Arabic participants.
During the EAPLT, all participating children showed no pragmatic language delay with a total pragmatic test score either at and/or above their fifth percentile. This coincides with findings in the study by Anderson and Conture  who agreed with many parents’ reports that their child showed a spurt in language development just before the onset of stuttering, speaking in longer sentences, and using new words.
The results are in contrast with those of Ratner  who considered language as a risk factor for stuttering and that there is a link between stuttering and language, especially in young children. This is because the onset of stuttering, typically between the ages of 2 and 4 years, coincides with the critical period of accelerated expansion in children’s expressive and receptive language. Moreover, a few current articles have supported the idea that stuttering is basically a disorder of language development .
Watkins and Johnson  reported that this discrepancy could be due to factors such as the age of the participants, the age of stuttering onset, time elapsed between onset and data collection for a study, the socioeconomic background of participants, time since the onset of stuttering, the types of language skills measured, and the tools used to measure it.
Further, 26.7% of children participating in this study had scores below their fifth percentile in the paralinguistic aspects (speech loudness, rate, intelligibility, fluency, and intonation). This explained that the score of the paralinguistic aspects involves scores of both speech fluency and intelligibility, which are affected to varying degrees in the CWS because of their stuttering.
This study concluded that there is no correlation between stuttering severity and pragmatic language development. There are two ways to explain this. First, language has three areas − form, content, and function (pragmatic) − and language delay would affect the three areas in any combination . In this study, delayed language development was one of the exclusion criteria for participating CWS; accordingly, development of language pragmatics, as one of the language domains, should not be delayed as well.
The second explanation is that stuttering severity correlates more obviously with the role-playing of the person who stutters, which necessitates constant self-monitoring. When the latter is reduced, the stuttering symptom and, consequently, its severity would reduce markedly . Taking this into consideration while assessing CWS − who are mostly unaware or annoyed by their stuttering symptoms, and whose parents alone are the sufferers − together with showing full acceptance of the child’s stuttering, made children adapted to the examiner and the assessment situation and, consequently, the stuttering symptoms and severity decreased.
The current study revealed that, typically, stuttering symptoms appeared more during a school situation, and only 5% of the participating children demonstrated a correlation between the appearance or the increase of stuttering symptoms with a specific spoken sound and/or word. This finding coincides with the results of Weiss  who reported that most language skills are learned by interactions. In terms of pragmatics, normally developing speakers can differentiate between the demands of different communication partners in different situations.
This can be explained by the fact that young children make assumptions about a listener’s knowledge level and adjust their speaking style to suit the listener. Consequently, putting a stuttering child under some type of pressure causes him or her to become aware of problems with his or her speech. Further, stuttering becomes increasingly chronic involving repetitions, prolongations, and blocks. Consequently, as stuttering progress, feelings of embarrassment and shame develop and secondary motor behaviors could appear during moments of stuttering or frustration, together with fear and avoidance of sounds, words, people, or speaking situations.
In contrast, Weiss and Zebrowski  reported that stories told by CWS, during a story-retelling task, were shorter than those told by children who do not stutter, irrespective of listeners.
Swiney and Reeves  referred the academic failure of CWS to the pragmatic weakness they could have. This is because CWS could have communication breakdown in the form of inability to seek repetition or clarification. Moreover, they are unable to know when to restate, explain, or revise their message leading to difficulty in using and benefiting from language in the classroom. In addition, they may have word avoidance behaviors as a sequel to their stuttering.
| Conclusion|| |
According to the EAPLT, all participating children had no pragmatic language delay. They had scores either at and/or above their fifth percentiles in all the test items except in the paralinguistic aspect. There is no statistically significant correlation between the grades of BLS classification and/or ASSI and the pragmatic language age.
