Social Phobia in Persian Adults with Stuttering

Background: Stuttering is a communication disorder. It is expected that stuttering may have negative impact on individuals’ mental and emotional health, which may affect their quality of life. Therefore, this paper aims to study components of social phobia inventory in Persian adults with stuttering and compare the likelihood (odds) of social phobia in the stuttering group to that in the control group. Methods: Using social phobia inventory, this case-control study compared social phobia in 33 adults with stuttering and 33 age-gender-education matched subjects with fluent speech. All the participants were 18 years or above. Results: Independent t-test showed that the total score of the social phobia inventory. Its fear component has significant statistical differences between group of adults with and without stuttering. Moreover, the adults with stuttering have over two times more social phobia symptoms than that in ones who don’t. Conclusion: Our results suggest that social phobia should be considered in therapy programs for adults with stuttering. In addition to restructuring speech, a part of the treatment program should address people’s social phobia, especially their feeling of fear, in order to curtail some of the negative consequences associated with stuttering

Prevalence and Risk Factors of Voice Disorders in University Teaching Faculty Members: A Pilot Study

Voice disorder is a multifactorial impairment. Several studies have shown that there is a direct relationship between voice problems and voice-related jobs. Therefore, professional voice users, including teachers, are at high risk of voice disorders, which threatens the employment positions. Also, the investigation of voice impairments among faculty members seems essential. The purpose of this study is to assess the prevalence of voice disorders in faculty members, its impact on the physical, emotional, and functional status of this job group, with and without voice disorders, and the correlation of voice disorders with some risk factors. Methods The participants of this study were 114 university teaching faculty members of Mashhad University of Medical Sciences, with a mean age of 43.95±0.98 years. The current cross-sectional descriptive-analytical study used a demographic questionnaire and Voice Handicap Index (VHI) as the data collection instruments. In the present study, based on VHI test results, participants with a total VHI score greater than 14.5 are considered to have voice disorders. Results The prevalence of voice disorders among university teaching faculty members was 27.19%. There was a significant correlation between allergy and voice disorders (P= 0.04). Significant differences were also found between the two study groups in terms of the total score of the VHI and its subscales (P <0.001). Conclusions Considering the 27.19% prevalence of voice disorders among university teaching faculty members and its effect on the total VHI score, our results confirm that education, prevention, and treatment programs are critical to lessen the frequency of voice disorders related to teaching. However, it has been found that this job group with voice disorders is four times more likely to have allergies than those without voice disorder, which indicates the importance of controlling this problem

Developing and Examining the Psychometrics of Single-word Quick Repetition Test for Speech Sound Production in Persian-speaking Children

Objectives: The present study aimed to develop and validate a quick repetition test using familiar and culture-based words for assessing Persian-speaking children with Speech Sound Disorders (SSDs). Methods: The study sample was divided into two groups, including 419 participants without any clinical signs of speech impairment and 36 cases with SSD. The psychometric properties of the single word quick repetition test, including reliability (inter-rater and test-retest reliability) and validity (construct, discriminant, convergent, clinical and concurrent validity) were examined. Moreover, the descriptive data for children without SSD were reported. Results: The obtained test-retest and inter-rater reliability data were satisfactory with Intraclass correlation coefficient (ICC): >0.7. There was a positive correlation between the results of the quick repetition test and phonetic test, indicating the scale's acceptable convergence validity. Using inflated beta-binomial regression, statistically significant improvement in test score was found with age (discriminant validity). Comparing the correct responses of the control and case groups (clinical validity) revealed a significant difference in responses between the study groups. Results of Bland–Altman plot suggested an acceptable agreement between quick repetition test and phonetic test (construct validity). Discussion: The Persian quick repetition test is a valid and reliable instrument facilitating the screening of speech sound abilities in 3-8-year-olds. Moreover, this test's conciseness makes it easily applicable in clinical practice and epidemiologic investigations. Establishing descriptive data from a large sample facilitated comparing children's speech ability to the speech development standards

Diagnostic Accuracy of the Photographic Expressive Persian Grammar Test to Identify 4-6 Years Old Children With Developmental Language Disorder

Objectives: Accurate diagnosis of Persian children with Developmental Language Disorder (DLD) is regarded as a challenge for Speech and Language Pathologists (SLPs) in Iran because of the lack of formal linguistic tests that can reliably distinguish language-impaired children from Typically-Developing (TD) children. This study aimed to investigate the diagnostic accuracy of the photographic expressive Persian Grammar Test (PEGT).  Methods: The participants were forty 4-6 years old monolingual Persian speakers who were categorized into two groups of DLD (n=20) and TD (n=20) children based on the MLU (mean length of utterance) scores as the reference standard and clinical judgment of an experienced speech-language pathologist. PEGT was administered to all participants, and the results were analyzed using the Mann-Whitney test and Rock Chart (ROC) to estimate the ability of the PEGT to differentiate between children with DLD and TD and to determine its sensitivity, specificity, and the optimal cutoff point.  Results: The results revealed that children with DLD performed significantly lower than their TD peers in the PEGT (P<0.05). Both sensitivity and specificity measures of PEGT were estimated as 100% at the optimal cut-off point of 12.5.  Discussion: The data provide empirical support for the use of the PEGT for accurate diagnosis of preschool children with DLD from their TD peers

Role of Basal Ganglia in Swallowing Process: A Systematic Review

Objectives: The basal ganglia (BG) controls different patterns of behavior by receiving inputs from sensory-motor and pre-motor cortex and projecting it to pre-frontal, pre-motor and supplementary motor areas. As the exact role of BG in swallowing process has not been fully determined, we aimed at reviewing the published data on neurological control in the swallowing technique to have a better understanding of BG&rsquo;s role in this performance.&nbsp; Methods: English-language articles, which were published before December 2015 and eligible for the present research, were extracted from databases according to the inclusion criteria, i.e. articles related to &ldquo;neurological aspects of swallowing&rdquo; and/or &ldquo;lesions of sub-cortical or BG relevant to swallowing disorders&rdquo;.&nbsp; Results: This systematic review indicates that BG is a complicated neurological structure with indistinct functions and that swallowing is a sophisticated process with several unknown aspects.&nbsp; Discussion: Swallowing is a multifaceted performance that needs contribution of the tongue, larynx, pharynx, and esophagus as well as the neurological structures such as neocortex and subcortical regions - BG and brainstem

Conversational repair strategies in 3 and 5 year old normal Persian-speaking children in Ahwaz, Iran

Background and Aim: The ability of conversational repair is a subset of pragmatic language. When the listener does not understand the speaker's intention, and the speaker cannot find a way of repairing the conversation to make his/her massage clear, communication will fail. This study aims to examine and compare the conversational repair skill in two groups of three and five year old children, to determine different conversational repair strategies and compare these skills among these groups.Methods: One hundred and twenty Persian speaking children of three and five years of Ahwaz, Iran, were selected. The study tools were two series of pictures. During the retelling of the pictures the examiner created a situation to elicit a conversational repair strategy. Percentages of the usage of different kinds of conversational repair in each group were calculated and compared using student's t-test.Results: The usage of repetition and inappropriate response is decreased in the group of five year olds compared to the three year olds, but cue-repair and repetition method is increased. The addition method has remained relatively constant. There was a significant difference between average percentage of using repetition (p=0.04) and cue-repair (p=0.001) of the two groups. The percentage of application of repetition method in three year olds and cue-term method in five year olds were significantly higher than other conversational repair strategies.Conclusion: With the increase in age and development of language skills the probability of using more complex and difficult strategies, like the cue-repair method, increases
