Interaction analysis is a critical component of clinical and public health research and represents a key topic in precision health and medicine. In applied settings, however, interaction assessment is usually limited to the test of a product term in a regression model and to the presentation of results stratified by levels of additional covariates. Stratification of results often relies on categorizing or making linearity assumptions for continuous covariates, with substantial loss of precision and of relevant information. In time-to-event analysis, moreover, interaction assessment is often limited to the multiplicative hazard scale by inclusion of a product term in a Cox regression model, disregarding the clinically relevant information that is captured by the absolute risk scale. In this paper we present a user-friendly procedure, based on the prediction of individual absolute risks from the Cox model, for the estimation and presentation of interactive effects on both the multiplicative and additive scales in survival analysis. We describe how to flexibly incorporate interactions with continuous covariates, which potentially operate in a nonlinear fashion, provide software for replicating our procedure, and discuss different approaches to deriving CIs. The presented approach will allow clinical and public health researchers to assess complex relationships between multiple covariates as they relate to a clinical endpoint, and to provide a more intuitive and precise depiction of the results in applied research papers focusing on interaction and effect stratification.

Background: Learner profiles detected from digital trace data are typically triangulated with survey data to explain those profiles based on learners' internal conditions (e.g., motivation). However, survey data are often analysed with limited consideration of the interconnected nature of learners' internal conditions. Objectives: Aiming to enable a thorough understanding of trace‐based learner profiles, this paper presents and evaluates a comprehensive approach to analysis of learners' self‐reports, which extends conventional statistical methods with psychological networks analysis. Methods: The study context is a massive open online course (MOOC) aimed at promoting physical activity (PA) for health. Learners' (N = 497) perceptions related to PA, as well as their self‐efficacy and intentions to increase the level of PA were collected before and after the MOOC, while their interactions with the course were logged as digital traces. Learner profiles derived from trace data were further examined and interpreted through a combined use of conventional statistical methods and psychological networks analysis. Results and Conclusions: The inclusion of psychological networks in the analysis of learners' self‐reports collected before the start of the MOOC offers better understanding of trace‐based learner profiles, compared to the conventional statistical analysis only. Likewise, the combined use of conventional statistical methods and psychological networks in the analysis of learners' self‐reports before and after the MOOC provided more comprehensive insights about changes in the constructs measured in each learner profile. Major Takeaways: The combined use of conventional statistical methods and psychological networks presented in this paper sets a path for a comprehensive analysis of survey data. The insights it offers complement the information about learner profiles derived from trace data, thus allowing for a more thorough understanding of learners' course engagement than any individual method or data source would allow. Lay Description: What is already known about this topic: Researchers have made extensive use of data from online learning platforms—often referred to as learning trace data—to understand how learners engage in online learning activities.Surveys are often used to gather information about learners' motivation, perceptions, and other internal factors, to complement the insight gleaned from learning traces and thus create a more complete picture of the learning behaviour.When analysing survey data, the focus is usually on individual factors without considering how different factors are connected and affect one another.Psychological networks analysis is a novel analytic approach to studying complex phenomena both in psychology and education. What this paper adds: The paper uses psychological networks as a method for examining mutual relations among learners' internal factors (e.g., motivation, perceptions) measured through self‐reports before and after a course.By combining conventional statistical analysis of self‐reports with psychological networks analysis, the paper develops a comprehensive picture of learners' internal factors measured through self‐reports, one that accounts for both individual and interconnected nature of those factors.This comprehensive approach to information extraction from surveys allows for better understanding of trace‐based learner profiles, that is, profiles mined from data about learners' interaction with online learning activities. Implications for practice and/or policy: The presented method paves a way for a comprehensive analysis of the data collected from learners through surveys.It helps us gain a better understanding of learners' engagement with online learning activities.It can advance the evaluation of digital educational programs that aim to encourage changes in health‐related behaviour.

Aim: Evidence shows that 20%–30% of patients who aspirate do so silently. Research to date has not demonstrated clear evidence to indicate which patients are at higher risk of silent aspiration. Our aim was to use univariate logistic regression analysis of retrospective case review to determine potential patterns of silent aspiration. Materials and methods: We conducted a retrospective analysis of 455 fiberoptic endoscopic evaluation of swallowing (FEES) reports. The patients were divided into four groups: G1 – neurological diseases (n = 93), G2 – head and neck surgery (n = 200), G3 – gastroenterological diseases (n = 94) and G4 – other patients (n = 68). Data included the occurrence or absence of saliva penetration or aspiration, of silent fluid/solid food penetration or aspiration, type of penetration or aspiration, occurrence of cranial nerve paresis, radiotherapy and tracheostomy. Univariate logistic regression was used to evaluate independent risk factors of silent aspiration in the study population. Three models with different independent variables were considered. Results: There is a statistically significant difference in the frequency of occurrence of silent penetration and aspiration within the groups (p < 0.001), with intraglutative being most frequent. Fluid and food penetration and aspiration correlated with saliva penetration and aspiration in all groups (p < 0.001). Cranial nerve paresis (IX and X), radiotherapy and tracheostomy correlate with saliva penetration and aspiration (p = 0.020 for cranial nerve paresis; p = 0.004 for radiotherapy; p < 0.001 for tracheostomy). One hundred and fifteen patients (45.81%) in the subgroup of patients with intraglutative aspiration had cranial nerve paresis (IX, X or IX–X). Conclusions: Patients who should be prioritised or considered to be at a higher need of instrumental swallowing evaluation are those with IX and X cranial nerve paresis, tracheostomy and those who have had radiotherapy, with saliva swallowing problems, especially after paraganglioma, thyroid and parathyroid glands and middle and posterior fossa tumour surgery. WHAT THIS PAPER ADDS: What is already known on the subject: Clinical signs of penetration or aspiration include coughing, throat clearing and voice changes, while silent penetration or aspiration patients aspirate without demonstrating any clinical symptoms. The most common consequences of silent aspiration include aspiration pneumonia, recurrent lower respiratory tract infections and respiratory failure. Additionally, malnutrition and dehydration can be indicators of silent aspiration. Patients may unknowingly reduce their oral intake and lose weight. Retrospective studies have shown that 20%–30% of patients aspirate silently (e.g. patients after stroke, acquired brain injury, head and neck cancer treatment, prolonged intubation). Clinical examination of swallowing can miss up to 50% of cases of silent aspiration. What this paper adds to existing knowledge: Currently, silent aspiration is often discussed in neurological literature, but its applications to head and neck surgery are limited. In this study, we identify head and neck surgery patients who should be prioritised or considered to be in higher need of instrumental swallowing evaluation due to a higher risk of silent aspiration. What are the potential or actual clinical implications of this work?: Post‐treatment structural changes can result in lower cranial nerve paresis (IX, X, XII) and face injury, in which vagus and glossopharyngeal nerves are injured. After tracheostomy and radiotherapy, patients with problems swallowing saliva need careful clinical examination, particularly cranial nerve examination. [ABSTRACT FROM AUTHOR]

Aim: Studies of the effects of COVID‐19, especially post‐acute COVID‐19 syndrome, on psychological health in non‐severe cases are limited. We aimed to evaluate the prevalence and associated risk factors of psychological symptoms, and quality‐of‐life in three groups of outpatients, hospitalized and intensive care patients. Methods: A total 276 patients, previously confirmed with SARS‐CoV‐2 infection, attending the COVID‐19 follow‐up outpatient clinic from December 2020 to July 2021 were interviewed face‐to‐face. In this cross‐sectional, retrospective study, all participants were asked our self‐designed demographic and screening questions to assess their psychological symptoms and administered the WHQOOL‐BREF survey to evaluate quality of life. Results: In screening questions, major depressive disorder symptoms were detected at a rate of 20.3%, generalized anxiety disorder symptoms at a rate of 16.7%, panic attack symptoms at a rate of 10.9%, post‐traumatic stress disorder symptoms at a rate of 28.6% and obsessive‐compulsive disorder symptoms at a rate of 18.1%. The outpatient group with COVID‐19 infection had a higher risk of developing psychological symptoms and decreased quality of life. Conclusion: COVID‐19 infection was found to have a considerable psychological impact on those treated as outpatients despite the less severe course of their illness. Summary statement: What is already known about this topic? Post‐intensive care syndrome affects physical, cognitive and psychological health.It is associated with symptoms such as generalized weakness, memory disturbances, cognitive function impairment, depression, anxiety and post‐traumatic stress disorder.Some physical and psychological symptoms persist for over 12 weeks in some patients and have been classified as 'Post‐acute COVID‐19 Condition or Syndrome' (PCS). What this paper adds? At the post‐acute‐COVID‐19 period, a considerable number of outpatients with COVID‐19 infection were at higher risk for psychological distress symptoms than those who had been treated in the hospital or intensive care unit.Depression, anxiety, panic disorder and PTSD symptoms were found to be higher in outpatients and those with these symptoms were also shown to have a lower quality of life.Our findings highlight the significant psychological impact of COVID‐19 on patients, even after their reported recovery from the acute manifestations of this disease. The implications of this paper: Ongoing psychological symptoms in the post‐COVID period are not associated with the severity of the disease in the acute phase.It is important that healthcare professionals are equally concerned not only with physical condition of post‐COVID‐19 patients but also with their psychological state and the patient's psychology‐related quality of life.

Background: The Turkish and Syrian earthquake on February 6th 2023, was one of the deadliest earthquakes in the last decade. It affected approximately 26 million people and left at least 50.000 dead. In this paper, we analyzed the psychological impact and the relationship between mental health factors, earthquake-related experiences and stressors, and resources related to the earthquake, 4 months after the event. Methods: We conducted an analytical cross-sectional study, applying a survey to 320 adults (18–93 years old) in Adiyaman, Turkey. Post-traumatic stress disorder (PTSD) symptoms were assessed using the PC-PTSD, general psychiatric morbidity using the GHQ-12, together with questions focusing on suicidality, drug abuse, as well as experiences, related stressors and received support related to the earthquake. Results: We found a high prevalence of general mental health symptoms, and of PTSD. Fear of aftershocks and the loss of close family members were found to be risk factors for such symptoms. We didn't find significant differences in the GHQ or the PC-PTSD scores when considering ethnicity, religion or financial income. Conclusions: High levels of general mental health symptoms and PTSD symptoms were found 4 months after the earthquake and need to be addressed in all groups, independently from potential religious, social or ethnic backgrounds. The results indicate a large psychiatric and material burden on the entire sample and some priority needs. [ABSTRACT FROM AUTHOR]

Objective: The LittlEARS® Early Speech Production Questionnaire (LEESPQ) was developed to provide professionals with valuable information about children's earliest language development and has been successfully validated in several languages. This study aimed to validate the Serbian version of the LEESPQ in typically developing children and compare the results with validation studies in other languages. Methods: The English version of the LEESPQ was back‐translated into Serbian. Parents completed the questionnaire in paper or electronic form either during the visit to the paediatric clinic or through personal contact. A total of 206 completed questionnaires were collected. Standardized expected values were calculated using a second‐order polynomial model for children up to 18 months of age to create a norm curve for the Serbian language. The results were then used to determine confidence intervals, with the lower limit being the critical limit for typical speech‐language development. Finally, the results were compared with German and Canadian English developmental norms. Results: The Serbian LEESPQ version showed high homogeneity (r =.622) and internal consistency (α =.882), indicating that it almost exclusively measures speech production ability. No significant difference in total score was found between male and female infants (U = 4429.500, p =.090), so it can be considered a gender‐independent questionnaire. The results of the comparison between Serbian and German (U = 645.500, p =.673) and Serbian and English norm curves (U = 652.000, p =.725) show that the LEESPQ can be applied to different population groups, regardless of linguistic, cultural or sociological differences. Conclusion: The LEESPQ is a valid, age‐dependent and gender‐independent questionnaire suitable for assessing early speech development in children aged from birth to 18 months. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to describe and compare the proportion of patients classified as an emergency department (ED) mental health presentation under different definitions, including the Australian Institute of Health and Welfare (AIHW) definition. Methods: This retrospective cohort study enrolled all patients that presented to the EDs of a multi-centre Victorian health service between 1 January 2020 and 30 June 2023. Varying definitions of a mental health presentation were applied to each ED attendance, applying the current AIHW definition (using selected diagnosis codes), broader diagnosis-based coding, the presenting complaint recorded at triage and whether the patient was seen by or referred to the emergency psychiatric service (EPS). The proportion of all ED presentations meeting each definition and any overlap between definitions were calculated. The agreement between each definition and the AIHW definition was evaluated using Kappa's coefficient. Results: There were 813,078 presentations to ED of which 34,248 (4.2%) met the AIHW definition for a mental health presentation. Throughout the study, 45,376 (5.6%) patients were seen and/or referred to EPS, and 36,160 (4.4%) patients were allocated a mental health presenting complaint by triage staff. There was moderate interrater agreement between these definitions, with a kappa statistic (95% confidence interval) between the AIHW definition and a mental health presenting complaint recorded at triage of 0.58 (0.58–0.59) and between the AIHW definition and review by EPS of 0.58 (0.57–0.58). Conclusions: The AIHW definition is a conservative measure of ED mental health presentations and may underestimate emergency psychiatry workload in Australian EDs. What is known about this topic? It is unknown whether the Australian Institute of Health and Welfare (AIHW) definition of an emergency department (ED) mental health presentation definition accurately reflects ED mental health workload. What does this paper add? The AIHW definition appears to underestimate the clinical workload related to ED mental health presentations. There is moderate agreement between the AIHW definition and mental health presentations classified according to complaint recorded at triage, or whether the patient is reviewed by psychiatry services. What are the implications for practitioners? Accurate measurement of emergency psychiatry workload should not rely on the AIHW definition alone. [ABSTRACT FROM AUTHOR]

Introduction: Media comparison studies examining the effectiveness of immersive virtual reality in education have yielded inconclusive findings, leaving the question of its impact on learning compared to conventional media unanswered. To address this issue, our study employs a novel approach that combines media comparison with an investigation on the influence of broader educational context. Methods: In the experiment, 262 students from two distinct types of lower secondary schools—comprehensive school and multi‐year gymnasium (a selective academic school)—participated. The students received a lesson on topography and contour line interpretation, using either an immersive virtual environment or a PowerPoint slideshow. A transfer test was carried out before, immediately after, and 1 month after the lesson to measure knowledge application. Results: The impact of the media (immersive virtual reality vs. PowerPoint slideshow) on learning outcomes was found to be minimal, with no clear advantage of one over the other in any experimental condition. In contrast, a significant influence on learning gains was observed due to school type. Multi‐year gymnasium students consistently outperformed comprehensive school students in the pre‐test and demonstrated greater learning gains, regardless of the learning media. Conclusion: The present study employs an innovative approach by integrating a comparative analysis of different media types with an investigation into the impact of learner characteristics. By including students from distinct types of schools, the study provides insights into the differential effects of immersive virtual reality in varied educational contexts. Lay Description: What is already known about this topic: Media comparison studies typically assess the effectiveness of immersive virtual reality as a learning medium in comparison to other instructional methods in education.The findings of these studies differ markedly.Numerous factors impact learning outcomes in an immersive virtual environment. What this paper adds: Recommendation that research in the field should explore not only if but also when and how IVR learning is effective.Evidence that learning achievements may not be affected by the medium used.Evidence that the type of school can significantly influence learning gains.Evidence that cognitive dispositions, such as spatial abilities, can be another factor that influence learning outcomes. Implications for practice: A technology‐centred approach alone does not allow for a proper evaluation of the learning gain potential of IVR, learner characteristics and broader educational context should also be taken into account.IVR as a learning medium may not be appropriate for all students and every educational setting.To ensure reliable evaluation of learning gains, it is necessary to align the content and format of the intervention in both learning mediums as closely as possible.Measuring learning gains not only immediately after the intervention but also with a significant time delay can contribute to a more comprehensive understanding.

Background: When parents bring their child to appointments and then adhere to agreed speech and language therapy (SLT) recommendations, there is the potential to increase the intensity of the intervention, support generalization and improve outcomes. In SLT, however, little is known about factors that may promote attendance or adherence. Studies in other clinical areas such in medicine, psychology and physiotherapy have identified risk factors for non‐attendance or non‐adherence that are multifactorial and variable dependent on, for example, population and intervention. Aims: To identify rates of non‐attendance and non‐adherence, and to identify parent or child factors associated with parent involvement in intervention for children under 5 years of age receiving SLT. Methods: Parents completed questionnaires at two time points assessing the domains of parents' beliefs (problem perceptions, self‐efficacy), personal circumstances (socio‐demographics, family functioning), treatment experience and child factors. Predictors of parent attendance and adherence were identified through multiple regression analyses. Non‐attendance rates were identified via local health records and non‐adherence ascertained using a specific parent‐reported measure within the treatment experience domain. Results: Participants (N = 199) were predominantly mothers, and were ethnically and socio‐economically diverse, speaking a wide range of languages. Their children presented with a range of speech, language communication needs (SLCN). The rate of non‐attendance was 25% and the main predictors of non‐attendance were maternal age, education level and two factors within the parent beliefs domain. This model explained 40% of the variance in attendance. The rate of non‐adherence in this cohort was 26% with parental rating of the importance of a recommendation and self‐efficacy beliefs predicting adherence; this explained 56% of the variance in adherence to SLT recommendations at home. Conclusions & Implications: Our research has provided preliminary evidence of the influence of parents' beliefs, personal circumstances and treatment experiences on their involvement in their child's therapy. Speech and language therapists should consider factors impacting attendance and adherence to treatment and explore parental perceptions of their child's SLCN before embarking on an intervention, a foundation for collaborative practice. A possible limitation of this study is that the levels of attrition in our sample led to generally high measured rates of participation, which should be considered in future studies. Future research should explore adherence in treatments with varying doses, with different types of SLCN or interventions and in different settings. WHAT THIS PAPER ADDS: What is already known on the subject: It is acknowledged that parent involvement in their child's therapy, such as attending and adhering to recommendations, is important but little is known about the rates of involvement and what factors may be associated with attendance and adherence in SLT. Qualitative research has explored parental involvement suggesting that beliefs about an intervention may be pertinent. Extensive research in other clinical areas suggest multiple and varied factors are influential and further exploration of particular populations and interventions is necessary. What this paper adds to the existing knowledge: This study identified rates of parental non‐attendance and non‐adherence in a cohort of predominantly mothers of children under the age of 5 years. It is the first study to measure parent adherence in SLT and identify factors that are associated parental adherence to SLT recommendations. It adds to the small body of SLT specific research in understanding risk factors for non‐attendance. What are the potential or actual clinical implications of this work?: This study highlights the need for a speech and language therapist to consider and explore parents' perspectives of their child's SLCN as a part of achieving collaboration with a parent in order to achieve the best outcomes. It provides a foundation for further systematic research into parent involvement with the ultimate aim of enhancing outcomes for children with SLCN. [ABSTRACT FROM AUTHOR]

Aims: This study aims to examine the prevalence of anxiety symptoms and identify predictors of anxiety among pregnant women with gestational diabetes mellitus and their partners and explore the mediating role of marital satisfaction between maternal and paternal anxiety. Design: A cross‐sectional study was conducted in Guangzhou, China, from July 2021 to May 2022. Methods: A total of 306 dyads of pregnant women with gestational diabetes mellitus and their partners completed the State–Trait Anxiety Inventory, Locke–Wallace Marital Adjustment Test and the socio‐demographic and clinical data sheet. Results: The prevalence of anxiety symptoms was 32.4% and 36.6% in pregnant women with gestational diabetes mellitus and their partners, respectively. The predictors of maternal anxiety were paternal anxiety, maternal marital satisfaction, maternal monthly salary, fasting glucose value and 1‐h glucose value. By contrast, the predictors of paternal anxiety were maternal anxiety, paternal marital satisfaction and paternal monthly salary. Moreover, the relationship between maternal and paternal anxiety was mediated by marital satisfaction. Conclusions: The anxiety symptoms of pregnant women with gestational diabetes mellitus and their partners influence each other, and this relationship was mediated by marital satisfaction. Every couple should be screened for anxiety symptoms and treated as a team rather than focusing solely on the pregnant woman. Summary statement: What is already known about this topic? Gestational diabetes mellitus is strongly associated with various short‐ and long‐term adverse maternal and neonatal outcomes.The diagnosis of gestational diabetes mellitus is stressful for pregnant women and their partners.No studies have been conducted to examine and compare the anxiety symptoms among pregnant women with GDM and their partners in mainland China. What this paper adds? The anxiety symptoms of pregnant women with gestational diabetes mellitus and their partners influence each other.The prevalence of anxiety symptoms was high in both pregnant women with gestational diabetes mellitus and their partners.Marital satisfaction played a mediating role between maternal and paternal anxiety. The implications of this paper: Study findings provide important information to guide future practice for nurses and other health‐care professionals.For the future, routine screening for anxiety symptoms is necessary for both pregnant women with gestational diabetes mellitus and their partners; mental health support should be delivered in a timely fashion for couples.Pregnant women with gestational diabetes mellitus and their partners should be treated as a team rather than focusing solely on pregnant women, with couples given training on enhancing marital satisfaction skills to prevent and reduce their anxiety symptoms.

The performance degradation of initiating explosive devices is influenced by various internal and external factors, leading to uncertainties in their reliability and lifetime predictions. This paper proposes an uncertain degradation model based on uncertain differential equations, utilizing the Liu process to characterize the volatility in degradation rates. The ignition delay time is selected as the primary performance parameter, and the uncertain distributions, expected values and confidence intervals are derived for the model. Moment estimation techniques are employed to estimate the unknown parameters within the model. A real data analysis of ignition delay times under accelerated storage conditions demonstrates the practical applicability of the proposed method. [ABSTRACT FROM AUTHOR]

Background: Down syndrome (DS) is a neurodevelopmental disorder of genetic origin with a cognitive‐behavioural profile that distinguishes it from other syndromes. Within this profile, language difficulties are particularly marked, having been more studied in childhood than in adulthood. More generally, there is a paucity of research on the prosodic skills of individuals with DS, despite the relevance of this linguistic component for effective communication. Aims: This study aimed to analyse, for the first time, the prosodic profile of Spanish‐speaking teenagers and young adults with DS. We hypothesized that participants with DS would show significantly lower skills for the perception and production of prosodic functions and forms when compared to peers with intellectual disability (ID) of unknown origin. We also hypothesized that teenagers and young adults with DS would have better prosody perception than prosody production. Methods & Procedures: The final sample included in the study comprised 28 Spanish‐speaking teenagers and young adults with DS and 29 teenagers and young adults with other ID matched on chronological age and nonverbal cognition. Their prosodic skills were tested by means of the Profiling Elements of Prosody for Speech and Communication battery. This battery allows for the separate evaluation of the comprehension and expression of the communicative functions of prosody and the discrimination and production of the forms that carry out such functions. Outcomes & Results: In the prosody function tasks, which are the most adaptive tasks for the communicative process, we found, as expected, significantly lower scores on the turn‐end, chunking, and focus tasks in the group with DS. However, no significant between‐group differences were found for the affect tasks. Participants with DS also had significantly lower scores on the prosodic form tasks than participants with other ID. The results of the comparison between prosodic perception and production skills showed that a generalization about a better profile in comprehension versus production is not possible and that there is a dependence on the demands of the prosodic task undertaken. Conclusions & Implications: The findings contribute to the ongoing development of the language profile of teenagers and young adults with DS and imply the need to design prosodic intervention programs based on their specific profile. WHAT THIS PAPER ADDS: What is already known on the subject: Prosody is a fundamental element of language, and its mastery affects the effectiveness of communication. However, research on prosody in Down syndrome (DS) that offers a holistic view from a psycholinguistic approach is still scarce. To date, studies focused on providing a detailed profile of prosodic skills in individuals with DS have been mainly conducted with a few English‐speaking children. These studies have shown that the comprehension and production of prosody is severely impaired, especially when considering affect and focus production, as well as the perception and production of prosodic forms. During childhood, greater efficacy is found in prosody comprehension than in prosody expression. What this study adds: This is the first study analysing the prosodic profile of a large group of Spanish‐speaking teenagers and young adults with DS. Poorer performance in the perception and production of both prosodic functions and forms was observed in participants with DS compared to participants with intellectual disability of unknown origin matched on chronological age and nonverbal cognition. Unlike what has been previously found in children, teenagers and young adults with DS performed at the same level as the control group on the understanding and expression of affect through prosodic cues. Results also showed that a generalization about a better prosody profile in comprehension versus production is not possible. What are the clinical implications of this work?: This study provides new data on the prosodic skills of Spanish‐speaking teenagers and young adults with DS. Given the impact of prosody on effective communication and the pattern of difficulties found in this study, speech and language therapists working with individuals with DS should consider including prosodic skills in interventions not only in childhood but also in adolescence and adulthood. Therefore, the prosodic profile of strengths and weaknesses in individuals with DS found in this research has direct implications for clinical practice. [ABSTRACT FROM AUTHOR]

This paper studies density estimation and regression analysis with data observed on a general unit hypersphere and contaminated by measurement errors. We establish novel density and regression estimators, and study their asymptotic properties such as the rates of convergence and asymptotic normality. We also provide two types of asymptotic confidence intervals for both density and regression functions. One type is based on the asymptotic normality of their estimators and the other type is based on the empirical likelihood technique. We present practical details on the implementation of our method as well as simulation studies and real data analysis. [ABSTRACT FROM AUTHOR]

In this paper, we present a practical approach for computing the sandwich variance estimator in 2-stage regression model settings. As a motivating example for 2-stage regression, we consider regression calibration, a popular approach for addressing covariate measurement error. The sandwich variance approach has rarely been applied in regression calibration, despite its requiring less computation time than popular resampling approaches for variance estimation, specifically the bootstrap. This is probably because it requires specialized statistical coding. Here we first outline the steps needed to compute the sandwich variance estimator. We then develop a convenient method of computation in R for sandwich variance estimation, which leverages standard regression model outputs and existing R functions and can be applied in the case of a simple random sample or complex survey design. We use a simulation study to compare the sandwich estimator to a resampling variance approach for both settings. Finally, we further compare these 2 variance estimation approaches in data examples from the Women's Health Initiative (1993–2005) and the Hispanic Community Health Study/Study of Latinos (2008–2011). In our simulations, the sandwich variance estimator typically had good numerical performance, but simple Wald bootstrap confidence intervals were unstable or overcovered in certain settings, particularly when there was high correlation between covariates or large measurement error.

Background: As delays or disorders in early language and communication are the most prevalent symptom in children with disabilities, early screening is crucial to promote prevention, early diagnosis, and intervention. However, to the best of our knowledge, no screening tool is available for the joint assessment of early language and social communication skills in European Portuguese (EP)‐learning children, which is critical for screening, monitoring and enrolment in appropriate early intervention services. Aims: (1) To adapt and validate the EP version of the Communication and Symbolic Behaviour Scales Developmental Profile™ (CSBS DP™) Infant–Toddler Checklist, a parental report for the screening of early language and social communication skills. (2) To conduct a cross‐cultural comparison between the EP adaptation and the original US version. Methods & Procedures: A total of 611 EP‐learning children (ages 6–24 months) were assessed on the CSBS DP Infant–Toddler Checklist. Normative data, psychometric characteristics (i.e., internal consistency and test–retest reliability), and cross‐cultural comparison between the EP and the original version were explored. Outcomes & Results: Internal consistency ranged from good to excellent and the test–retest reliability was excellent. The performance of the EP and US samples matched on almost all scores. However, EP children performed significantly better than their American peers in the Social compositive at 22 months and in the Symbolic composite at 20 months. No further differences were found. Conclusions & Implications: These findings showed that the EP CSBS DP Infant–Toddler Checklist seems to be a reliable screening tool of communicative and symbolic behaviours for EP‐learning children, which can be particularly relevant for decision‐making in clinical practice. WHAT THIS PAPER ADDS: What is already known on the subject: Early communication skills are known to be related to later language outcomes. Thus, screening tools for the early identification of children at risk for language and communication impairments, which may lead to monitoring and early intervention, have the potential to promote better outcomes. However, to the best of our knowledge, no screening tool is available for the assessment of early communication abilities in EP‐learning children. What this paper adds to existing knowledge: This study adapted and validated the EP CSBS DP Infant–Toddler Checklist, the first published parental report checklist for the assessment of early communication skills in EP. It described the psychometric characteristics of the adapted checklist, summarized the newly available normative data for EP‐learning infants and toddlers, and compared the performance of EP‐learning children with the original standardization sample reported for American English. The results demonstrated that this tool is a reliable instrument for the early screening of language, communicative and symbolic behaviours for EP‐learning children between 6 and 24 months of age. What are the potential or actual clinical implications of this work?: Given that early screening is crucial to promote prevention, early diagnosis and intervention, the availability of this tool is particularly relevant for children monitoring and their enrolment in appropriate early intervention services, helping decision‐making in clinical practice, in line with current guidelines regarding early monitoring and intervention to promote and support better outcomes. Thus, the tool and related normative data will be useful for paediatricians, family doctors, primary healthcare providers, developmental psychologists and speech–language therapists, among other professionals in the healthcare and educational fields, concerned with speech, language, and communication development and impairments.

To investigate determinants of willingness to adopt telerehabilitation, willingness of technology use, core affect regarding using telerehabilitation, and digital competencies in rehabilitation professionals in Austria and Germany before and during the COVID-19 pandemic. A cross-sectional paper-based and online survey was conducted before and during COVID-19, respectively, with three cohorts of rehabilitation professionals. Outcomes were the willingness to adopt telerehabilitation evaluated using the extended Unified Theory of Acceptance and Use of Technology; willingness of technology use using the short scale for assessing the willingness of technology use; digital competencies and core affect using the Digital Competence Framework and semantic differential, respectively. Multivariate ordinal regression analysis was performed to determine predictors. Included were 603 rehabilitation professionals. Analysis revealed differences between Austria and Germany and before and during the pandemic for most outcomes. German residency, the pandemic, and a higher educational level were most important predictors of higher willingness to adopt telerehabilitation, willingness of technology use, digital competencies, and positive core affect. The pandemic increased most aspects of willingness to adopt telerehabilitation, willingness of technology use, digital competencies, and positive core affect. Results confirm that rehabilitation professionals with higher degrees are more prone to adopt innovations in healthcare.Registration: German Clinical Trials Register (DRKS00021464) The willingness to adopt telerehabilitation is associated with external factors increasing the need for alternative rehabilitation delivery, such as COVID-19, and with financial facilitators, such as reimbursement. As the willingness to adopt telerehabilitation is higher among speech and language therapists and dietitians, efforts are necessary to enhance its use in physiotherapists and occupational therapists. As a higher willingness to adopt telerehabilitation was observed in younger rehabilitation professionals and those with higher education, increasing the importance of telerehabilitation in education curricula and further knowledge transfer into practice for those already working in the field seems necessary.

Background: Gender dysphoria among transgender adolescents has predominantly been examined in relation to body dissatisfaction. While in adult transgender samples, body dissatisfaction is higher than in cisgender controls, this has so far rarely been investigated for adolescents. In the context of a cisnormative society, the impact of influences from the social environment on body dissatisfaction and gender dysphoria has been neglected in research. Therefore, this study aimed to (1) provide a detailed analysis of body dissatisfaction among young transgender people and (2) investigate whether body dissatisfaction and gender dysphoria are associated with experiences of minority stress such as trans hostility and poor peer relations (PPR). Methods: The paper presents a cross-sectional study among a sample of transgender adolescents, presenting at a specialized outpatient counseling clinic (N = 99; age M = 15.36, SD = 1.85). First, body dissatisfaction (assessed by the Body-Image-Scale; BIS), was explored and compared to data from a population-based control group of cisgender peers (N = 527; age M = 14.43, SD = 0.97). Second, within a clinic-referred transgender subsample (n = 74), associations between body dissatisfaction and gender dysphoria (measured by Utrecht Gender Dysphoria Scale; UGDS), PPR (measured by the Youth-Self-Report; YSR-R), and trans hostile experiences (assessed in clinical interview) were examined by correlations, t-tests and multivariate regression. Results: Transgender adolescents reported more body dissatisfaction than cisgender peers. The dissatisfaction with sex characteristics, non-hormonal reactive body regions and the total score for body dissatisfaction were positively related with gender dysphoria. The majority had experienced trans hostility in the present and/or past (54.1%) and PPR (63.5%). More body dissatisfaction was correlated with more PPR regarding visible body parts i.e., hair, overall appearance and muscles, whilst PPR and gender dysphoria were not associated. Transgender adolescents who experienced trans hostility showed higher gender dysphoria and PPR, but not more body dissatisfaction. In multiple regression, trans hostility predicted gender dysphoria, whilst age and PPR predicted body dissatisfaction. Discussion: Experiences of minority-stress differentially interact with body dissatisfaction and gender dysphoria among transgender adolescents. Social correlates of body dissatisfaction and gender dysphoria must be considered when working with young transgender people. [ABSTRACT FROM AUTHOR]

In this paper, we study the empirical likelihood and estimation of parameters of interest in a partially linear varying coefficient model with right censored data. Two cases are considered: censoring is independent of the covariates, and censoring depends on the covariates. The bias-corrected empirical log-likelihood ratios for the regression parameters are presented, Wilks' theorem is proved, and thus the confidence regions of the regression parameters are constructed. The estimators of parametric and nonparametric components are constructed, their asymptotic distributions are obtained, and the consistent estimators of the asymptotic variances are also given. Furthermore, the partial profile empirical log-likelihood ratios for each component of the regression parameters and the coefficient functions are constructed, and show they are asymptotically chi-squared. The obtained results can be directly used to construct the confidence regions/intervals for the regression parameters and the pointwise confidence intervals for the coefficient functions. Our approach is to directly calibrate the empirical log-likelihood ratio so that the resulting ratio is asymptotically chi-squared, undersmoothing of the coefficient functions is avoided, and existing data-driven methods can be effectively used to select the optimal bandwidth. Simulation studies compare the empirical likelihood method with one based on normal approximation and perform real data analysis. [ABSTRACT FROM AUTHOR]

Objective: To evaluate and compare performance in the modified shuttle walk test (MSWT) with cardiorespiratory parameters and respiratory muscle strength in children with cystic fibrosis (CF) and healthy controls. Methods: A cross‐sectional study with children divided into the CF group (CFG) and healthy control group (HCG). Two MSWTs were performed and the data from the test with the longest distance walked and its cardiorespiratory parameters (blood pressure, respiratory rate, heart rate (HR), oxygen saturation, and dyspnea sensation) were considered, the last three every 4 levels. Respiratory muscle strength was evaluated using a manometer. The Wilcoxon test was used to compare the parameters before and after the MSWT, and the Mann‐Whitney and independent t‐tests were applied to compare the data between the groups. The distance walked and its association with the variation in cardiorespiratory parameters and respiratory muscle strength were analyzed by Spearman's correlation. Results: Sixty‐two children (31 in each group) participated, with an average age of 10.2 (2.1) years. Children with CF had poorer performance in the average distance walked (CFG 716.7 (274.3)) when compared to the HCG (948.0 (202.8)). Both groups exhibited an increase in all the cardiorespiratory parameters at the end of the test, but the CFG displayed less variation in some parameters. Children with CF presented a positive correlation between distance walked and respiratory muscle strength, HR variation, and systolic blood pressure. Conclusions: There was no difference in respiratory muscle strength between the groups. In the CFG, the greater the respiratory muscle strength, the better the performance in the MSWT. The CFG exhibited less variation in cardiorespiratory parameters than the HCG. Implications for physiotherapy practice: Current knowledge Maximum Effort Tests provide detailed information on physiological health and enable exercise prescription.Exercise performance could be limited in children with cystic fibrosis (CF).Exercise performance is usually associated with obstruction to expiratory airflow in CF. What this paper contributes to our knowledgeChildren with CF show preserved respiratory muscles strengthPulmonary function and respiratory muscles strength were related to exercise performance by modified shuttle walk test (MSWT).Child collaboration influences test performance.

Background: Very young children from lower socioeconomic status (SES) backgrounds often show poorer language development. Whilst there have been attempts to provide early intervention programmes, these sometimes miss the most disadvantaged groups. Aims: This report presents preliminary feasibility and effectiveness data for a novel language intervention designed for parents of toddlers in the United Kingdom. Methods and Procedures: In total, 43 UK families of 2–4‐year‐olds were recruited to the study, half of whom completed an 8‐week course (Tots Talking) focussed on parent interaction, and half of whom acted as wait‐list controls. Results and Outcomes: Results suggest that such programmes are feasible for families with 86% staying in the intervention. In addition, greater changes in underlying communication skills such as joint attention and gesture were evident compared to wait‐list controls. Conclusions and Implications: We conclude that pre‐verbal skills may be more important to measure as initial outcomes than language or vocabulary change in this population. What This Paper Adds: What is already known on the subject: Children from lower socioeconomic status (SES) backgrounds are at higher risk of communication difficulties and there is a need for community intervention programmes for very young children. What this study adds: This study suggests that such programmes can be feasible and effective, but that very early/basic communicative skills (such as joint attention) may be boosted first rather than language or vocabulary. What are the clinical implications of this work?: Children's centres and other community services could feasibly run short parent facing courses emphasising contingent communication in low SES families and other diverse groups. These may be more successful run with younger preschoolers. Joint attention may be a better focus of intervention before expecting vocabulary or language change. Community health professionals may find this information useful in referring and supporting families in need. [ABSTRACT FROM AUTHOR]
