Background: The Gugging Swallowing Screen (GUSS) is a bedside dysphagia screening tool that has been designed to determine the risk of aspiration in acute stroke patients. There is no evidence in the literature for the GUSS for the pediatric population. The present study aimed to determine the diagnostic accuracy of GUSS as a screening tool in the Greek language for children with dysphagia. Methods: Eighty‐Greek‐Cypriot children aged 3–12 years who had dysphagia participated in this retrospective study. The translated into Greek GUSS was administered twice (pre‐ and post‐therapy) to each patient throughout 24 sessions of dysphagia therapy. Key Results: The GUSS showed a high internal consistency (Cronbach's α = 0.826), good test–retest reliability (rs = 0.767), convergent validity compared to the Greek Pediatric Eating Assessment tool‐10 (PEDI‐EAT‐10) total score (rs = −0.365), and inter‐rater reliability (κ = 0.863). A total cutoff points equal to 13.00 was also calculated. Aspiration was identified by the GUSS with low sensitivity and high specificity (PPV 100%, NPV 57%, LR+ NA, LR− 0.79); dysphagia/penetration was identified with high sensitivity and low specificity (PPV 33%, NPV 100%, LR+ 0.102, LR− NA). Conclusions & Inferences: The pediatric version of GUSS has been found to be a valuable tool in identifying the risk of aspiration as that of adults. It proved to be used as a good screening guide for selecting and confirming the existence of dysphagia from instrumental assessments. This is the first study of the pediatric version of GUSS, and future studies on this topic are needed. [ABSTRACT FROM AUTHOR]

Background: Diadochokinetic (DDK) rate tasks are extensively used in the evaluation of speech disorders; however, it is unclear how the different types of speech stimuli affect DDK rate performance. Aims: To investigate the effect of age, gender and type of stimuli (non‐words versus real words) on the DDK rates in individuals across the lifespan and to provide normative data for Greek. Also to examine the discrimination ability of the speech DDK stimuli administered (non‐words and real words) based on a dual DDK assessment protocol using a polytomous item response theory (IRT) model. Methods & Procedure: The participants were 1747 monolingual Greek speakers (376 children, aged 4–17 years; and 1371 adults, aged 18–90+ years). All participants had normal hearing acuity which allowed them to understand and follow instructions. Participants with a medical condition or a language disorder which would affect DDK rate performance were excluded from the study. The time‐by‐count method was used, and all participants had to repeat as accurately and fast as possible: (1) four disyllabic non‐words (/'gaba/, /'taka/, /'kata/, /'baga/), (2) four disyllabic real words (/'kapa/, /'tapa/, /ka'la/, /'paka/) and (3) two trisyllabic non‐words (/'pataka/, /'badaga/). All responses were recorded and the speech samples that did not include at least 5 s of correct repetitions were excluded from the analysis. Outcomes & Results: Age affected significantly DDK rates with performance increasing gradually until approximately the age of 40 and then gradually decreasing. Gender had no effect. Overall, there was a significant advantage of disyllabic real word stimuli over disyllabic non‐word stimuli and of trisyllabic non‐word stimuli over disyllabic non‐word stimuli on DDK rates performance. IRT analysis suggested that the data fit the polytomous model reasonably well and all DDK stimuli (real words and non‐words) showed a strong relationship (loadings > 0.50) with the latent trait. Conclusions & Implications: The current study complements prior research which supports that age and type of stimuli significantly affect DDK rates performance. It is the first study, that testifies to the benefit of real‐word stimuli over non‐word stimuli on DDK rates across the lifespan in a large representative sample. The implementation of IRT analysis provides empirical evidence about the discrimination ability of the DDK stimuli administered and confirms the reliability of this dual DDK assessment protocol. These findings are valuable for clinicians who work with motor speech disorders. WHAT THIS PAPER ADDS: What is already known on this subject: Age, type of stimuli (real words versus non‐words) and language significantly affect DDK rates performance. Current research strongly suggests the administration of language‐specific norms since language‐dependent features seem to have a noteworthy effect on the DDK rates, but scarce evidence exists about the discriminatory ability of the DDK speech stimuli commonly administered. What this study adds to the existing knowledge: Conflicting findings have been reported about the effect of different types of DDK speech stimuli (real words and non‐words) but no study to date has evaluated their discriminatory abilities. The current study is the first to implement a polytomous IRT model to examine this issue. This is also the first study to attempt an investigation of the effect of types of stimuli (real words versus non‐words) on a large representative sample across the lifespan (4–90+ years) and to provide normative data for Greek. What are the practical and clinical implications of this work?: The present study offers concrete evidence about the advantage of real‐word stimuli over non‐word stimuli in Greek, as well as normative data for the Greek‐speaking populations. Moreover, the IRT analysis testifies to the discriminatory ability of real‐word and non‐word stimuli affirming the reliability of the present dual DDK assessment protocol as a psychometrically sound measure of DDK ability. The above has significant value for clinicians who work with individuals with motor speech disorders as the protocol can help them with the diagnosis and differential diagnosis of motor speech disorders.

AbstractPurposeMaterials and MethodsResultsConclusions\nIMPLICATIONS FOR REHABILITATIONThe Pediatric Eating Assessment Tool (PEDI-EAT-10) is a parents/caregivers screening tool that assesses pediatric patients at risk of penetration and/or aspiration symptoms. The aim of this study was the validation of PEDI-EAT-10 in the Greek language.This cross-sectional study included 222 parents/caregivers of children with (n = 122) and without (n = 100) feeding and/or swallowing disorders, with age range 3 – 12 years. The children were selected from Cypriot schools and health settings. All parents filled out the PEDI-EAΤ-10 questionnaire and after its initial completion, it was re-administered after 2 weeks.A statistically significant difference was observed in the PEDI-EAT-10 total mean scores between the study’s two groups [t (220) = 9.886, p < 0.001]. Internal consistency was high (Cronbach’s alpha= 0.801) with very good split-half reliability equal to 0.789. A significant and strong test-retest reliability was computed (r = 0.998, p < 0.001). The PEDI-EAT-10 cutoff point was 11.00 (AUC: 0.869, p < 0.001) for children with feeding and/or swallowing disorders in accordance with the PAS scale.In conclusion, the Greek version of PEDI-EAT-10 is shown to be a valid and reliable screening tool for the assessment of the pediatric population with a risk of dysphagia.The Pediatric Eating Assessment Tool (PEDI - EAT - 10) is a clinical screening tool to assess pediatric patients at risk of penetration and/or aspiration reported by parents or caregivers.This study is a cross cultural translation of PEDI - EAT - 10 in Greek language and it is proven to have excellent internal consistency, reliability, and validity.The use of PEDI – EAT – 10 will be a very useful utility for health professionals in rehabilitation settings.The Pediatric Eating Assessment Tool (PEDI - EAT - 10) is a clinical screening tool to assess pediatric patients at risk of penetration and/or aspiration reported by parents or caregivers.This study is a cross cultural translation of PEDI - EAT - 10 in Greek language and it is proven to have excellent internal consistency, reliability, and validity.The use of PEDI – EAT – 10 will be a very useful utility for health professionals in rehabilitation settings.
