Show moreVisuoperceptual evaluation of fiberoptic endoscopic evaluation of swallowing (FEES) is a commonly used assessment in dysphagia or swallowing disorders. Currently, no international consensus exists regarding which visuoperceptual measures to use for the analysis of FEES recordings. Moreover, existing visuoperceptual FEES measures are limited by poor and incomplete psychometric data, identifying an urgent need for developing a visuoperceptual measure to interpret FEES recordings. Following the COSMIN group's (COnsensus-based Standards for the selection of health Measurement INstruments) psychometric taxonomy and guidelines, this study aimed to establish the content validity of a new visuoperceptual FEES (V-FEES) measure in adults with oropharyngeal dysphagia. Using the Delphi technique, international consensus was achieved among dysphagia experts across 21 countries, resulting in a new prototype measure for V-FEES, comprising 30 items, 8 function testing items (i.e., specific tasks performed by patients while observing and rating items), and 36 unique operationalisations (i.e., defining items into measurable factors that could be measured empirically using visuoperceptual observation). This study supports good content validity for V-FEES, including participants' feedback on the relevance, comprehensiveness, and comprehensibility of the included items. Future studies will continue the instrument development process and determine the remaining psychometric properties using both the classic test theory (CTT) and item response theory (IRT) models.

Show moreIntroduction: This study examined speech language pathologists' use of standardized language measures when assessing school-aged children. Method: A total of 335 Speech Language Pathologist (SLP)s provided information in a web-based survey regarding the standardized language measures they use for school-aged children. SLPs were asked to identify the domains targeted, purposes of use and reasons for which regularly used standardized measures were chosen for use. Results: Findings indicated that SLPs collectively use many standardized measures, although only a small number are used regularly. SLPs reported using standardized measures to assess domains that measures are not ideally designed for and for purposes that the measures were not ideally suited to assessing. SLPs reported selecting diagnostic measures based on psychometric properties, but not for screening measures. Reasons for choice varied depending on the particular measure. Conclusion: Overall, findings indicated that SLPs need to place greater focus on evidence-based practice recommendations when selecting standardized measures for use with school-aged children. Implications for clinical practice and future directions are discussed. Show less

Show moreIntroduction: Patient self-evaluation is an important aspect in the assessment of dysphagia and comprises both Functional Health Status (FHS) and Health-Related Quality of Life (HR-QoL). As many measures combine both FHS and HR-QoL, disease-related functioning cannot be distinguished from disease-related quality of life as experienced by the patient. Moreover, current patient self-reported measures are limited by poor and incomplete data on psychometric properties. Objective. This study aimed to establish content validity for the development of two new self-reported measures on FHS and HR-QoL in adults with oropharyngeal dysphagia (OD), in line with the psychometric taxonomy and guidelines from the COSMIN group (COnsensus-based Standards for the selection of health Measurement INstruments). Methods. Using the Delphi technique, international expert consensus was achieved; participants and patients with dysphagia evaluated relevance, comprehensiveness, and comprehensibility of definitions of relevant constructs (i.e., dysphagia, FHS and HR-QoL) and potential items. Results: A total of 66 Delphi participants from 45 countries achieved consensus across two rounds. The Delphi study resulted in two prototype measures, the Functional health status measure of Oropharyngeal Dysphagia (FOD) and the health-related Quality of life measure of Oropharyngeal Dysphagia (QOD), consisting of 37 and 25 items, respectively. Minimal revisions were required based on feedback by patients. Conclusions: This study provides evidence of good content validity for both newly developed prototype measures FOD and QOD. Future studies will continue the process of refining the measures, and evaluate the remaining psychometric properties using both Classic Test Theory (CTT) and Item Response Theory (IRT) models.

Show moreAims: Child maltreatment (CM) is a global public health and social problem, resulting in serious long-term health and socioeconomic consequences. As parents are the most common perpetrators of CM, parenting interventions are appropriate strategies to prevent CM. However, research on parenting interventions on CM has been hampered by lack of consensus on what measures are most responsive to detect a reduction in parental maltreating behaviours after parenting intervention. This systematic review aimed to evaluate the responsiveness of all current parent- or caregiver-reported CM measures. Methods: A systematic search was conducted in CINAHL, Embase, ERIC, PsycINFO, PubMed and Sociological Abstracts. The quality of studies and responsiveness of the measures were evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines for systematic reviews of patient-reported outcome measures. Only measures developed and published in English were included. Studies reporting data on responsiveness of the included measures were selected. Results: Sixty-nine articles reported on responsiveness of 15 identified measures. The study quality was overall adequate. The responsiveness of the measures was overall insufficient or not reported; high-quality evidence on responsiveness was limited. Conclusions: Only the Physical Abuse subscale of the ISPCAN Child Abuse Screening Tool for use in Trials (ICAST-Trial) can be recommended as most responsive for use in parenting interventions, with high-quality evidence supporting sufficient responsiveness. All other overall scales or subscales of the 15 included measures were identified as promising based on current data on responsiveness. Additional psychometric evidence is required before they can be recommended. Show less

Show moreThe visuoperceptual measure for videofluoroscopic swallow studies (VMV) is a new measure for analysing the recordings from videofluoroscopic swallow studies (VFSS). This study evaluated the reliability and validity of the pilot version of the VMV using classical test theory (CTT) analysis, informed by the consensus-based standards for the selection of health measurement instruments (COSMIN) guidelines. Forty participants, diagnosed with oropharyngeal dysphagia by fibreoptic endoscopic evaluation of swallowing, were recruited. The VFSS and administration of bolus textures and volumes were conducted according to a standardised protocol. Recordings of the VFSS were rated by three blinded raters: a speech-language pathologist, a radiologist and a phoniatrician. Inter- and intra-rater reliability was assessed with a weighted kappa and resulted in 0.889 and 0.944 overall, respectively. Structural validity was determined using exploratory factor analyses, which found four and five factor solutions. Internal consistency was evaluated with Cronbach's alpha coefficients, which found all but one factor scoring within an acceptable range (>0.70 and <0.95). Hypothesis testing for construct validity found the expected correlations between the severity of dysphagia and the VMV's performance, and found no impact of gender on measure performance. These results suggest that the VMV has potential as a reliable and valid measure for VFSS. Further validation with a larger sample is required, and validation using an item response theory paradigm approach is recommended. Show less

Show moreObjective: To determine the effects of behavioural interventions in people with oropharyngeal dysphagia. Methods: Systematic literature searches were conducted to retrieve randomized controlled trials in four different databases (CINAHL, Embase, PsycINFO, and PubMed). The methodological quality of eligible articles was assessed using the Revised Cochrane risk-of-bias tool for randomised trials (RoB 2), after which meta-analyses were performed using a random-effects model. Results: A total of 37 studies were included. Overall, a significant, large pre-post interventions effect size was found. To compare different types of interventions, all behavioural interventions and conventional dysphagia treatment comparison groups were categorised into compensatory, rehabilitative, and combined compensatory and rehabilitative interventions. Overall, significant treatment effects were identified favouring behavioural interventions. In particular, large effect sizes were found when comparing rehabilitative interventions with no dysphagia treatment, and combined interventions with compensatory conventional dysphagia treatment. When comparing selected interventions versus conventional dysphagia treatment, significant, large effect sizes were found in favour of Shaker exercise, chin tuck against resistance exercise, and expiratory muscle strength training. Conclusions: Behavioural interventions show promising effects in people with oropharyngeal dysphagia. However, due to high heterogeneity between studies, generalisations of meta-analyses need to be interpreted with care. Show less

Show moreObjective. To assess the effects of neurostimulation (i.e., neuromuscular electrical stimulation (NMES) and pharyngeal electrical stimulation (PES)) in people with oropharyngeal dysphagia (OD). Methods. Systematic literature searches were conducted to retrieve randomised controlled trials in four electronic databases (CINAHL, Embase, PsycINFO, and PubMed). The methodological quality of included studies was assessed using the Revised Cochrane risk-of-bias tool for randomised trials (RoB 2). Results. In total, 42 studies reporting on peripheral neurostimulation were included: 30 studies on NMES, eight studies on PES, and four studies on combined neurostimulation interventions. When conducting meta analyses, significant, large and significant, moderate pre-post treatment effects were found for NMES (11 studies) and PES (five studies), respectively. Between-group analyses showed small effect sizes in favour of NMES, but no significant effects for PES. Conclusions. NMES may have more promising effects compared to PES. However, NMES studies showed high heterogeneity in protocols and experimental variables, the presence of potential moderators, and inconsistent reporting of methodology. Therefore, only conservative generalisations and interpretation of meta-analyses could be made. To facilitate comparisons of studies and determine intervention effects, there is a need for more randomised controlled trials with larger population sizes, and greater standardisation of protocols and guidelines for reporting.

Show moreObjective. To assess the effects of brain neurostimulation (i.e., repetitive transcranial magnetic stimulation [rTMS] and transcranial direct current stimulation [tDCS]) in people with oropharyngeal dysphagia (OD). Methods. Systematic literature searches were conducted in four electronic databases (CINAHL, Embase, PsycINFO, and PubMed) to retrieve randomised controlled trials (RCTs) only. Using the Revised Cochrane risk-of-bias tool for randomised trials (RoB 2), the methodological quality of included studies was evaluated, after which meta-analysis was conducted using a random-effects model. Results. In total, 24 studies reporting on brain neurostimulation were included: 11 studies on rTMS, 9 studies on tDCS, and 4 studies on combined neurostimulation interventions. Overall, within-group meta-analysis and between-group analysis for rTMS identified significant large and small effects in favour of stimulation, respectively. For tDCS, overall within-group analysis and between-group analysis identified significant large and moderate effects in favour of stimulation, respectively. Conclusion. Both rTMS and tDCS show promising effects in people with oropharyngeal dysphagia. However, comparisons between studies were challenging due to high heterogeneity in stimulation protocols and experimental parameters, potential moderators, and inconsistent methodological reporting. Generalisations of meta-analyses need to be interpreted with care. Future research should include large RCTs using standard protocols and reporting guidelines as achieved by international consensus.

Show morePurpose: Language intervention for children with language disorder may be effective; however, lack of detailed and consistent terminology for describing language interventions poses barriers for advancement within the field. This study aimed to develop consensus from speech-language pathologists (SLPs) in Australia on a taxonomy with terminology for describing language interventions for school-aged children and investigate SLPs' application of taxonomy terminology when describing child language interventions. Method: A taxonomy with terms for describing interventions was developed with reference to contemporary literature and presented to clinicians and researchers with expertise in child language disorders in a three-round Delphi study. We asked Delphi participants to indicate agreement with the taxonomy or propose changes. Application of the taxonomy was investigated by asking participants to use taxonomy terminology to describe interventions presented in two case studies. Results: The taxonomy consists of five aspects across which interventions may be described: modality/domain, purpose, delivery, form, and teaching techniques. Consensus on the taxonomy was established in both Round 1 (55 participants) and Round 2 (43 participants), with 100% of SLPs strongly agreeing or agreeing with the overall structure of the taxonomy and at least 87.3% of SLPs strongly agreeing or agreeing with each aspect. In Round 3 (32 participants), consensus was reached on 45/54 taxonomy categories (4/12 of the components) for Case Study 1 and 45/54 taxonomy categories (7/12 of the components) for Case Study 2. Conclusions: Consensus on a taxonomy with terminology for describing language interventions represents a significant advancement in the field of child language intervention. Future actions may be needed to facilitate consistent application of taxonomy terms. Supplemental Material: https://doi.org/10.23641/asha. 16435290 Show less

Show moreIn school, shyness is associated with psychosocial difficulties and has negative impacts on children's academic performance and wellbeing. Even though there are different strategies and interventions to help children deal with shyness, there is currently no comprehensive systematic review of available interventions. This systematic review and meta-analysis aim to identify interventions for shy children and to evaluate the effectiveness in reducing psychosocial difficulties and other impacts. The methodology and reporting were guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and checklist. A total of 4,864 studies were identified and 25 of these met the inclusion criteria. These studies employed interventions that were directed at school-aged children between six and twelve years of age and described both pre- and post-intervention measurement in target populations of at least five children. Most studies included an intervention undertaken in a school setting. The meta-analysis revealed interventions showing a large effect in reducing negative consequences of shyness, which is consistent with extant literature regarding shyness in school, suggesting school-age as an ideal developmental stage to target shyness. None of the interventions were delivered in a classroom setting, limiting the ability to make comparisons between in-class interventions and those delivered outside the classroom, but highlighting the effectiveness of interventions outside the classroom. The interventions were often conducted in group sessions, based at the school, and involved activities such as play, modelling and reinforcement and clinical methods such as social skills training, psychoeducation, and exposure. Traditionally, such methods have been confined to a clinic setting. The results of the current study show that, when such methods are used in a school-based setting and involve peers, the results can be effective in reducing negative effects of shyness. This is consistent with recommendations that interventions be age-appropriate, consider social development and utilise wide, school-based programs that address all students. Show less

Show morePurpose: This study reports on data from a survey of speech-language pathologists' (SLPs) language assessment practices for elementary school-age children. The objective was to investigate the regularity with which SLPs use different types of assessments (described across data types, task types, environmental contexts, and dynamic features). This study also investigated factors that influence assessment practice, the main sources from which SLPs obtain information on language assessment and the main challenges reported by SLPs in relation to language assessment.Method: A web-based survey was used to collect information from 407 Australian SLPs regarding the types of assessments they use. Factors that influenced the regularity with which different types of assessments were used were investigated using regression analysis.Results: Most SLPs regularly used assessments that are norm-referenced, decontextualized, and conducted in a clinical context and less regularly used other types of assessments. Service agency, Australian state, and SLPs' years of experience were found to influence the regularity with which some types of assessments were used. Informal discussions with colleagues were the most frequently identified source of information on assessment practice. Main challenges related to limited time, lack of assessment materials, and lack of confidence in assessing children from culturally and linguistically diverse backgrounds.Conclusions: SLPs could improve current language assessment practice for elementary school-age children through more regular use of some types of assessments. Actions to facilitate evidence-based assessment practice should consider the contextual differences that exist between service agencies and states and address challenges that SLPs experience in relation to language assessment.

Show moreTo determine the effects of non-pharmacological randomised controlled trials in adults with autism, a systematic review was conducted across five electronic databases. A total of 3865 abstracts were retrieved, of which 41 articles met all inclusion criteria: randomised controlled trial; non-pharmacological intervention; adults with autism; and English publication. Twenty included studies had strong methodological quality ratings. No meta-analysis could be performed due to heterogeneity between studies. Articles reported on interventions for (1) social functioning and language skills, (2) vocational rehabilitation outcomes, (3) cognitive skills training, and (4) independent living skills. Social functioning was the most studied intervention. PEERS for young adults and Project SEARCH plus ASD support interventions had the strongest evidence. Emerging evidence suggests non-pharmacological interventions could be effective. Show less

Show moreThis White Paper by the European Society for Swallowing Disorders (ESSD) reports on the current state of screening and non-instrumental assessment for dysphagia in adults. An overview is provided on the measures that are available, and how to select screening tools and assessments. Emphasis is placed on different types of screening, patient-reported measures, assessment of anatomy and physiology of the swallowing act, and clinical swallowing evaluation. Many screening and non-instrumental assessments are available for evaluating dysphagia in adults; however, their use may not be warranted due to poor diagnostic performance or lacking robust psychometric properties. This white paper provides recommendations on how to select best evidence-based screening tools and non-instrumental assessments for use in clinical practice targeting different constructs, target populations and respondents, based on criteria for diagnostic performance, psychometric properties (reliability, validity, and responsiveness), and feasibility. In addition, gaps in research that need to be addressed in future studies are discussed. The following recommendations are made: (1) discontinue the use of non-validated dysphagia screening tools and assessments; (2) implement screening using tools that have optimal diagnostic performance in selected populations that are at risk of dysphagia, such as stroke patients, frail older persons, patients with progressive neurological diseases, persons with cerebral palsy, and patients with head and neck cancer; (3) implement measures that demonstrate robust psychometric properties; and (4) provide quality training in dysphagia screening and assessment to all clinicians involved in the care and management of persons with dysphagia.

Show moreIntroduction Over the past decade there has been a marked growth in the use of linked population administrative data for child protection research. This is the first systematic review of studies to report on research design and statistical methods used where population-based administrative data is integrated with longitudinal data in child protection settings.MethodsThe systematic review was conducted according to Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. The electronic databases Medline (Ovid), PsycINFO, Embase, ERIC, and CINAHL were systematically searched in November 2019 to identify all the relevant studies. The protocol for this review was registered and published with Open Science Framework (Registration DOI: 10.17605/OSF.IO/96PX8)ResultsThe review identified 30 studies reporting on child maltreatment, mental health, drug and alcohol abuse and education. The quality of almost all studies was strong, however the studies rated poorly on the reporting of data linkage methods. The statistical analysis methods described failed to take into account mediating factors which may have an indirect effect on the outcomes of interest and there was lack of utilisation of multi-level analysis.ConclusionWe recommend reporting of data linkage processes through following recommended and standardised data linkage processes, which can be achieved through greater co-ordination among data providers and researchers.

Show moreThe Deglutition Handicap Index (DHI) is a self-report measure for patients at risk of oropharyngeal dysphagia on deglutition-related aspects of functional health status (FHS) and health-related quality of life (HR-QoL). The DHI consists of 30 items which are subsumed within the Symptom, Functional and Emotional subscales. The purpose of this study was to evaluate the psychometric properties of the DHI using Classic Test Theory according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. A total of 453 patients with dysphagia with different aetiologies were recruited concurrently at two academic hospitals. Dysphagia was confirmed by fiberoptic endoscopic and/or videofluoroscopic evaluation of swallowing. In addition, a healthy control group of 132 participants were recruited. Structural validity was determined using exploratory and confirmatory factor analyses and internal consistency by calculating Cronbach's alpha coefficients. Hypothesis testing was evaluated using Mann-Whitney U-tests, linear regression analysis and correlations analysis. Diagnostic performance and receiver operating characteristic curves analysis were calculated. Factor analyses indicated that the DHI is a unidimensional measure. The DHI has good internal consistency with some indication of item redundancy, weak to moderate structural validity and strong hypothesis testing for construct validity. The DHI shows high diagnostic performance as part of criterion validity. These findings support that the DHI is an appropriate choice as a patient self-report measure to evaluate FHS and HR-QoL in dysphagia. Ongoing validation to assess the measure for possible item redundancy and to examine the dimensionality of the DHI using item response theory is recommended. Show less

Show morePurpose To develop a European White Paper document on oropharyngeal dysphagia (OD) in head and neck cancer (HNC). There are wide variations in the management of OD associated with HNC across Europe. Methods Experts in the management of specific aspects of OD in HNC across Europe were delegated by their professional medical and multidisciplinary societies to contribute to this document. Evidence is based on systematic reviews, consensus-based position statements, and expert opinion. Results Twenty-four sections on HNC-specific OD topics. Conclusion This European White Paper summarizes current best practice on management of OD in HNC, providing recommendations to support patients and health professionals. The body of literature and its level of evidence on diagnostics and treatment for OD in HNC remain poor. This is in the context of an expected increase in the prevalence of OD due to HNC in the near future. Contributing factors to increased prevalence include aging of our European population (including HNC patients) and an increase in human papillomavirus (HPV) related cancer, despite the introduction of HPV vaccination in various countries. We recommend timely implementation of OD screening in HNC patients while emphasizing the need for robust scientific research on the treatment of OD in HNC. Meanwhile, its management remains a challenge for European professional associations and policymakers. Show less

Show moreIntroduction. Although play has been used as a means to meet therapeutic goals by health care practitioners for a long time, there is a need to continuously review its conceptualisation and use in everyday practice to promote evidence-based practice. This systematic review aimed to evaluate the evidence on how the play of children with Special Health Care Needs (SHCN) is similar or different to that of typically developing children. Methods. Guided by the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, we conducted a comprehensive review across five electronic databases for all studies that compared how the play of children with SHCN was similar or different to that of typically developing children. Data were extracted from the included studies, and methodological quality was assessed. Results. Eighteen studies met eligibility criteria. All the studies in this review were at risk of bias due to the study design. There was great variation in sample sizes, ranging between five and 112 participants in the diagnostic groups and five and 546 participants in control groups (typically developing children). The included studies investigated different aspects of play, which made it difficult to synthesise. However, of the 18 studies reviewed, thirteen reported that children with SHCN engage in less play, compared with typically developing children. Conclusions. Evidence supports the assumption that children with SHCN are less playful and spend less time engaging in play compared with typically developing children. This systematic review reveals paucity of research on play for children with several common chronic conditions such as HIV/AIDS, cancer, and cardiovascular diseases. Future studies need to reduce risks of bias, including the use of appropriate sample sizes, and must provide detailed results after investigating play in children with SHCN. Show less

Show moreIntroduction The Videofluoroscopic Swallow Study (VFSS) is a commonly used dysphagia assessment that is routinely analysed visuoperceptually. However, no consensus exists regarding which visuoperceptual measures should be used to analyse VFSSs. Current visuoperceptual measures for VFSSs are limited by poor quality and incomplete or indeterminate psychometric properties. Objective This study aimed to establish the content validity for a new visuoperceptual VFSS measure for oropharyngeal dysphagia in adults, by identifying relevant domains of the construct and generating items and corresponding response scales. Methods Consensus among experts in dysphagia and VFSS from over 20 countries was achieved across three rounds of anonymous online surveys, using the Delphi technique. Participants judged relevance and comprehensiveness of definitions of visuoperceptual domains of VFSS and the relevance of various domains to the overall construct. After reaching consensus on definitions of relevant domains, consensus on items were established using the same process. Results Participants achieved consensus on definitions of 32 domains recommended for analysis, and at least one item per domain (range 1-4). Domains selected by participants included both those which occur in existing measures and domains which have not been included in any measures to date. This study will form the basis for content validity of a new measure for VFSS. Conclusions This first phase of developing a visuoperceptual measure of VFSS resulted in the identification of 32 domains and 60 items for oropharyngeal dysphagia. Developers can now advance to the next phase of measure construction; prototype development and psychometric testing. Show less

Show morey This study investigated speech-language pathologists' (SLPs) perceptions of factors that influence application of a new taxonomy with terminology for describing child language assessment and identified strategies that may facilitate use of taxonomy terminology to collect data on SLP assessment practice. Semi-structured interviews were conducted with 13 SLPs and data were analyzed using thematic analysis. Three main themes were identified in relation to factors that may influence application including applying the taxonomy is arduous, contextual factors may influence application, and SLP experience and knowledge may influence application. Participants identified a number of strategies to facilitate use of taxonomy by SLPs. Findings from this study give insight into the factors that influence SLPs' application of a taxonomy of assessment terms. These findings are important for all SLPs in the child language field to consider if the profession is to be effective in establishing greater consistency in use of professional terminology.
