    Background: Feeding difficulties and dysphagia can lead to malnutrition, dehydration, pneumonia, prolonged hospitalization, and even death in neonates. Accordingly, it should be recognized as soon as possible to provide necessary medical care, nursing, and rehabilitation. This study aimed to translate the Neonatal Feeding Assessment Scale (NFAS) into Persian and determine its psychometric properties in Iranian neonates.Methods: After receiving permission from developers, the main version of NFAS was translated into Persian. Face validity of NFAS was assessed by 10 qualified speech and language pathologists in the field of pediatric swallowing. In order to define the internal consistency of the items, 52 infants were evaluated using the Persian version of NFAS, and the correlation between the items was determined using Kuder-Richardson 20. The test-retest and inter-rater reliabilities were also calculated by Cohen's Kappa coefficient in 30 and 40 infants, respectively. The convergent reliability between NFAS and Early Feeding Skills (EFS) was calculated by point-biserial correlation in 30 infants.Results: According to experts, all translated items were transparent and understandable. The internal consistency score was obtained at 0.76. Moreover, Cohen's Kappa coefficients were calculated at 0.96 and 0.87 for test-retest and inter-rated reliabilities, respectively. Point biserial correlation between Persian NFAS and EFS was estimated at 0.63.Conclusion: Persian version of NFAS is a valid and reliable tool to assess feeding problems and oro-pharyngeal dysphagia in infants and make clinical decisions

    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

    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

    Background and Aim: Specific language impairment (SLI), one variety of developmental language disorder, has attracted much interest in recent decades. Much research has been conducted to discover why some children have a specific language impairment. So far, research has failed to identify a reason for this linguistic deficiency. Some researchers believe language disorder causes defects in phonological working memory and affects auditory processing speed. Therefore, this study reviews the results of research investigating these two factors in children with specific language impairment.Recent Findings: Studies have shown that children with specific language impairment face constraints in phonological working memory capacity. Memory deficit is one possible cause of linguistic disorder in children with specific language impairment. However, in these children, disorder in information processing speed is observed, especially regarding the auditory aspect.Conclusion: Much more research is required to adequately explain the relationship between phonological working memory and auditory processing speed with language. However, given the role of phonological working memory and auditory processing speed in language acquisition, a focus should be placed on phonological working memory capacity and auditory processing speed in the assessment and treatment of children with a specific language impairment

    Background and Aim: Many studies have demonstrated a close relationship between phonological working memory and language abilities in normal children and children with language developmental disorders, such as those with cochlear implants. A review of these studies would clarify communication and learning in such children and provide more comprehensive information regarding their education and treatment. In this study, the characteristics of phonological working memory and its relationship with language abilities in children with cochlear implants was examined.Recent Findings: In this study, the authors studied the characteristics of phonological working memory and its relationship with language abilities of children with cochlear implants. These studies showed that in addition to demographic variables, phonological working memory is a factor that affects language development in children with cochlear implants. Children with cochlear implants typically have a shorter memory span.Conclusion: It is thought that the deficiency in primary auditory sensory input and language stimulation caused by difficulties in the processing and rehearsal of auditory information in phonological working memory is the main cause of the short memory span in such children. Conversely, phonological working memory problems may have adverse effects on the language abilities in such children. Therefore, to provide comprehensive and appropriate treatment for children with cochlear implants, the reciprocal relationship between language abilities and phonological working memory should be considered

    Objectives: Some children are at risk of middle ear infections; however, the impact of the fluctuating hearing sensations on cognitive systems and immature central auditory is not fully recognized. Therefore, we reviewed and discussed the impact of early-otitis media on the cognitive skills of affected school-aged children. Methods: A computerized search of the databases was conducted between January 2000 and December 2020 using the following keywords, including “otitis media” and “cognition” or “attention” or “memory” or “working memory” or “short term memory”. Results: After applying inclusion and exclusion criteria and appraising the quality, seven studies were included and the data were extracted. Some of the articles reported a relationship between otitis media with effusion (OME) and cognitive deficits in 5 years old children and the other studies did not yield significant association. Discussion: It seems that children with OME experience difficulties in attention and memory; though, the relationship between early childhood OME and cognitive skills in children at school ages is not yet definitive and need more comprehensive and well-organized studies

    Objectives: Since there is no reliable and valid tool to assess all features of children’s phonological skills whose first language is Azeri, speech-language pathologists usually use informal or Persian instruments. So, it is essential to develop a tool in Azeri language for assessing articulation and phonological skills. For this reason, this study aimed to develop an Azeri Phonological Test (APT) and then determine the validity and reliability of this test in 4-6 years old children whose first language is Azeri. Methods: Participants were 77 (41 boys and 36 girls; 4-6 years old) typically-developing children. They were selected by cluster sampling method. Firstly, Tabriz City in Iran was geographically divided into three sections, namely south, north, and center. Then, the kindergartens of each area were randomly selected for sampling. The participants were assigned into 2 groups: 48-60 months (n=38) and 61-72 months (n=39) old. To assess the phonological skills, nine stories were designed. An expert panel with 15 speech-language pathologists investigated the content validity of the stories. Then the psychometric characteristics of the APT, including reliability (test-retest reliability, inter-rater, and internal consistency) and validity (construct –known group validity), were assessed. The statistical tests used were intraclass correlation coefficient (intra-rater reliability and test-retest), Kuder-Richardson 21 (internal consistency), and the independent samples t-test (known-groups validity). Results: The content validity of the whole test was 0.91. Construct validity evaluation showed that age affects the test scores but not gender. There was a significant correlation between the results of test-retest and inter-rater reliability, and also, the test had a high internal consistency.  Discussion: Based on the findings, APT is a reliable and valid test for assessing the abilities of 4-6 years old children in terms of the production of sounds in the context of retelling stories

    Objective: In this study, a new training method of working memory (WM) was used in the form of structured games, and the effect of training was evaluated with a controlled design. The training method of WM in the form of structured games includes 20 sets of structured games that can improve WM and performance of executive functions. Method: Sixty children with attention deficit hyperactivity disorder (ADHD) aged 8.5 to 11.2 years (35 boys), using no stimulant medication were selected. We randomly assigned 30 participants to the experimental group and provided them with WM training. The training was in the form of structured games and was offered to the participants in two 60-minute sessions weekly for 12 weeks. Other participants were assigned to the control group, receiving no treatment. All the participants were also evaluated at follow-up 6 months later. The main measures were the Child Behavior Checklist (CBCL), the Digit Span and Symbol Search B subscale of the Wechsler Intelligence Scale for Children (WISC-IV); and scores of dictation and mathematics were used in terms of pre and post-test. Results: The results of the t-test revealed a significant improvement in the post-test measures as well as a significant reduction of parents’ reports of inattentiveness, and improvement in academic performance in the experimental group. However, no significant changes were found in the control group. Conclusion: The academic and working memory improvements were primarily due to the training method of WM. Our findings suggest that the training method of WM in the form of structured games may be a practical method for treating children with ADHD, but it needs to be further investigated

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

    No full text
    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

    A systematic review on diagnostic procedures for specific language impairment: The sensitivity and specificity issues

    No full text
    Background: Identification of children with specific language impairment (SLI) has been viewed as both necessity and challenge. Investigators and clinicians use different tests and measures for this purpose. Some of these tests/measures have good psychometric properties, but it is not sufficient for diagnostic purposes. A diagnostic procedure can be used for identification a specific population with confidence only when its sensitivity and specificity are acceptable. In this study, we searched for tests/measures with predefined sensitivity and specificity for identification of preschool children with SLI from their typically developing peers. Materials and Methods: A computerized search in bibliographic databases from 2000 to August 2015 was performed with the following keywords: "specific language impairment" or SLI" and "primary language impairment" or ′PLI′ with at least one of the followings: "diagnosis," "identification," "accuracy," "sensitivity," and "specificity." In addition, the related citations and reference lists of the selected articles were considered. Results: The results of reviewing 23 included studies show that the index measures used in studies vary in accuracy with the sensitivity ranging from 16% to 100% and the specificity ranging from 14% to 100%. Conclusion: These varieties in sensitivity and specificity of different tests/measures confirm the necessity of attention to the diagnostic power of tests/measures before their use as diagnostic tool. Further, the results indicate there are some promising tests/measures that the available evidence supports their performances in the diagnosis of SLI in preschool-aged children, yet the place of a reference standard for the diagnosis of SLI is vacant among investigations
