Parent-mediated interventions for promoting communication and language development in young children with Down syndrome

Interventions to address parenting stress among caregivers of children with chronic diseases: An umbrella review

BACKGROUND

Caregivers of children with chronic diseases suffer from great parenting pressure, which directly affects the treatment and rehabilitation of children, reduces the quality of life of caregivers and damages family functioning. Existing reviews have not systematically summarized and evaluated interventions for parenting stress in caregivers of children with chronic diseases.

DATA SOURCES

Embase, PubMed, Web of Science, OVID, CNKI, CBM, Wan Fang and Cochrane Library were searched for eligible reviews in November 2021 and October 2022.

METHODS

Two reviewers independently screened titles and abstracts, reviewed full texts of articles for eligibility, and appraised the quality of reviews using JBI. The quality of the evidence was assessed using GRADE. Findings are reported in accordance with PRISMA checklist. Narrative summaries grouped findings by intervention types.

RESULTS

Out of 2632 records, we included 21 systematic reviews for a synthesis. Interventions for parenting stress in children with chronic diseases were divided into seven categories. Cognitive behavioural interventions, psychosocial interventions, child behavioural and/or developmental parent interventions and synthesized interventions have shown high-level evidence in reducing parenting stress for caregivers of children with chronic diseases. Furthermore, outcome measures and intervention protocols were highly heterogeneous across interventions.

CONCLUSIONS

This umbrella review suggest that reducing the parenting stress of caregivers of children with chronic diseases can directly target caregivers' parenting stress through cognitive behavioural interventions/psychosocial interventions and/or provide guidance to parents on the behavioural and developmental problems of children with chronic diseases. A more standardized approach to outcome measures is essential to assess efficacy and compare interventions across studies.

RELEVANCE TO CLINICAL PRACTICE

The findings provide information and evidence for reducing parenting stress among caregivers of children with chronic diseases to guide the development of comprehensive intervention strategies.

Early educational attainment in children with major congenital anomaly in the UK

OBJECTIVE

To describe early educational attainment and special educational needs (SEN) provision in children with major congenital anomaly (CA) compared with peers.

DESIGN

Analysis of educational data linked to the ongoing Born in Bradford cohort study. Confounders were identified via causal inference methods and multivariable logistic regression performed.

SETTING

Children born in Bradford Royal Infirmary (BRI), West Yorkshire.

PATIENTS

All women planning to give birth at BRI and attending antenatal clinic from March 2007 to December 2010 were eligible. 12 453 women with 13 776 pregnancies (>80% of those attending) were recruited. Records of 555 children with major CA and 11 188 without were linked to primary education records.

OUTCOMES

Key Stage 1 (KS1) attainment at age 6-7 years in Maths, Reading, Writing and Science. SEN provision from age 4 to 7 years.

RESULTS

41% of children with major CA received SEN provision (compared with 14% without), and 48% performed below expected standards in at least one KS1 domain (compared with 29% without). The adjusted odds of children with CA receiving SEN provision and failing to achieve the expected standard at KS1 were, respectively, 4.30 (95% CI 3.49 to 5.31) and 3.06 (95% CI 2.47 to 3.79) times greater than their peers. Those with genetic, heart, neurological, urinary, gastrointestinal and limb anomalies had significantly poorer academic achievement.

CONCLUSIONS

These novel results demonstrate that poor educational attainment extends to children with urinary, limb and gastrointestinal CAs. We demonstrate the need for collaboration between health and education services to assess and support children with major CA, so every CA survivor can maximise their potential.

The feasibility of measuring fidelity of implementation in parent-child interaction therapy: A clinician and parent fidelity study

PURPOSE

Measuring fidelity of implementation in parent-child interaction therapy (PCIT) involves assessing the training delivered by clinicians and how parents implement the techniques with their children. The aim of this study was to determine the feasibility of measuring fidelity of implementation for a PCIT intervention designed for young children with Down syndrome.

METHOD

We applied a framework to measure dosage, adherence, quality, and participant responsiveness using a mixed methods approach with observational and interview data.

RESULT

Our results showed that clinicians delivered 94% of the planned dosage; they adhered to the goals of program and reached the quality criterion in 4/6 rated sessions. Parents described their ability to engage with the program and perceived that it changed how they interacted and communicated with their children. Parents were unable to collect dosage data, but did adhere to 7/9 of the targeted techniques and met the quality criterion on 6/9 of these. It was also possible to measure the children's responsiveness scores when interacting with parents during the intervention.

CONCLUSION

This study revealed the opportunities and challenges that occur when measuring fidelity of implementation. There is a need to refine definitions of fidelity measures and to develop appropriate measurement tools so that a more consistent and useful framework can be used by speech-language pathologists (SLPs) to measure fidelity.

Health-related quality of life and family functioning of primary caregivers of children with down syndrome

Background

Down Syndrome (DS; OMIM #190685), known as trisomy 21, is one of the most common genetic disorders in the human population and the commonest known cause of intellectual disability. The study was conducted to investigate the quality of life (QoL) of children with DS syndrome and its impact on family functioning.

Purpose of study

To assess the quality of life of children with trisomy 21 and the impact of the disorder on the family.

Methods

We used a cross-sectional questionnaire study. The respondents were 52 parents of children with trisomy 21. The following structured questionnaires were used: the PedsQL™ 4.0 Generic Core Scales, the PedsQL™ Family Impact Module and Study-Specific Questionnaire (SSQ).

Results

The combined scores, with a mean value of approximately 55 out of a possible 100 points, indicated a significant impact of the child's genetic defect on family functioning. In the overall QOL, the highest rated domain was physical functioning (x̅ =60.14; SD = 23.82) and the lowest was school functioning (x̅ =51.36; SD = 18.72). Better school functioning (p = 0.022) was reported for girls. The presence of reduced muscle tone also had a negative impact on the child's functioning in the physical (p = 0.036), emotional (p = 0.011), psychosocial (p = 0.027) and overall QOL domains (p = 0.023).

Conclusion

Overall, our results showed that the quality of life of children with trisomy 21 is impaired. There was a positive association between the child's QOL and the QOL of their parents, as well as the general functioning of the child's whole family. For this reason, an improvement in the QOL of parents and the family functioning is closely related to an increased QOL of the child. The continuous deepening of knowledge of QOL in individual trisomy 21 management allows for better preparation and ongoing care for the patients concerned.

Cognitive Therapy for Children with Intellectual Disabilities: A New Look at Social Adaptation Skills and Interpersonal Relationships

The purpose of the study is to consider the factors influencing the development of the culture of interpersonal relationships and the effectiveness of the influence of cognitive therapy on improving social adaptation skills. The method of cognitive therapy included several types of activities. The first type of activities included group sessions, during which the weaknesses of the interaction and their correction were identified. The second type was conducted in the format of teaching standard models of interaction between people. The third type of activity aimed to teach children to build a dialogue with each other and express their desires and emotions. Classes were held 3 times a week throughout the year. The study was attended by pupils of 5-7 grades of Zhanuya boarding school and special correctional boarding school No. 7 for children with intellectual disabilities. The results of a randomized study demonstrated an increase in the indicators of teamwork skills, self-control, emotional stability, and independent decision-making. The indicators of cheerfulness, openness, sociability, and logical thinking also improved. But the factor of antisocial behavior decreased. All of these indicators directly affect socialization. This strategy can be applied in practice in various specialized boarding schools and schools for children with intellectual disabilities.

What has been done to improve learning for intellectual disability? An umbrella review of published meta-analyses and systematic reviews

BACKGROUND

Intellectual disability (ID) affects 1%-3% of the paediatric population. Currently, there is no consensus as to the most effective strategies for improving the learning skills of children and adolescents with ID. This review aims to systematically gather information regarding interventions to promote and improve learning skills in children/adolescents with ID from previously published systematic reviews and meta-analyses.

METHODS

Systematic search strategies, including appropriate descriptors, were employed on Medline, Cochrane, Scopus, Web of Science, Lilacs, SciELO, ERIC, and PsycINFO databases. Quality assessment was conducted via the AMSTAR-2.

RESULTS

Fifty-nine studies were selected, subdivided by outcome domains and by the type of intervention. Interventions were related to caregiving, education, pharmaco-dietary, physical, and technology approaches. The overall low quality of the studies limited our recommendations.

A pilot randomised controlled trial on the effectiveness of infant massage on the acceptance, commitment and awareness of influence in parents of babies with Down syndrome

BACKGROUND

The emotional state of parents of babies with Down syndrome affects their babies' development and their parent-child bonding. The aim for this study was to conduct a pilot randomised controlled evaluation of the effect of infant massage on parents of babies with Down syndrome.

METHODS

This pilot study compared two groups (intervention and control), each with 16 parents of babies with Down syndrome. Indices of acceptance, engagement and awareness of influence were measured at two different time points (pre-test and after 5 weeks) using the 'This Is My Baby' Interview. The allocation of families to each group was randomised. The experimental group performed infant massage, applied by the parents, for 5 weeks, every day for at least 10 min. The massage protocol was based on the methodology created by Vimala McClure. Parents in the control group received the intervention after completion of the study.

RESULTS

The indices of acceptance, commitment and awareness of influence improved in the experimental group and in the control group. The 2 × 2 mixed-model analysis of variance indicates a statistically significant group-by-time interaction for all indices (P < 0.001), which was significantly higher in the experimental group than in the control group.

CONCLUSIONS

The application of infant massage, by parents to their babies, improves the rates of acceptance, commitment and awareness of influence of parents of babies with Down syndrome in the short term.

Executive functioning and verbal fluency performance in youth with Down syndrome

BACKGROUND

Executive functioning (EF) is an area of challenge for individuals with Down syndrome (DS) associated with a variety of downstream difficulties. Verbal fluency performance is one potential downstream effect that is commonly assessed in individuals with DS due to the measure's utility as a predictor of dementia. Verbal fluency requires individuals to inhibit irrelevant responses, shift between groupings of related words, and monitor to prevent repetition, all skills related to EF.

AIMS

This study aimed to determine the association between semantic verbal fluency performance and three EF subdomains (inhibition, shifting, and working memory) in youth with DS after taking into account vocabulary and cognitive ability.

METHODS AND PROCEDURES

Neuropsychological assessments (verbal and visuospatial), and parent reports of EF, were completed at one time point by 69 youth with DS 6-17 years old and their caregivers. Expressive and receptive vocabulary skills and cognitive ability were also assessed.

OUTCOMES AND RESULTS

The results revealed that verbal fluency performance was significantly associated with neuropsychological assessments of EF and parent report of inhibition even after controlling for the effects of vocabulary and cognitive ability.

CONCLUSIONS AND IMPLICATIONS

The findings highlight the underlying importance of EF in verbal fluency tasks in youth with DS.

A systematic review of speech, language and communication interventions for children with Down syndrome from 0 to 6 years

BACKGROUND

Speech and language acquisition can be a challenge for young children with Down syndrome (DS), and while early intervention is important, we do not know what early interventions exist and how effective they may be.

AIMS

To systematically review existing early speech, language and communication interventions for young children with DS from birth up to 6 years, and to investigate their effectiveness in improving speech, language and communication outcomes in children with DS. Other outcomes are changes in parental behaviour and their responsiveness METHODS & PROCEDURES: We conducted a systematic search of relevant electronic databases to identify early intervention studies targeting speech, language and communication outcomes in children with DS published up to May 2020. A total of 11 studies that met the inclusion criteria were synthesized and appraised for quality using the PEDro-P scale. There were a total of 242 children. We identified three types of intervention: communication training and responsive teaching, early stimulation programme, and dialectic-didactic approach.

MAIN CONTRIBUTION

The findings from nine out of the 11 studies reported positive outcomes for children's language and communication up to 18 months following the intervention. All nine studies reported interventions that were co-delivered by parents and clinicians. However, there was also a de-accelerated growth in requesting behaviours in the intervention group reported by one study as well as a case of no improvement for the intervention group. Three studies provided some evidence of improvements to parent outcomes, such as increased parental language input and increased responsiveness. However, there was a moderate to high risk of bias for all studies included.

CONCLUSIONS

The findings from this review suggest that interventions that have high dosage, focus on language and communication training within a naturalistic setting, and are co-delivered by parents and clinicians/researchers may have the potential to provide positive outcomes for children with DS between 0 and 6 years of age. Due to the limited number of studies, limited heterogeneous data and the moderate to high risk of bias across studies, there is an urgent need for higher quality intervention studies in the field to build the evidence base.

WHAT THIS PAPER ADDS

What is already known on the subject Speech and language acquisition is usually delayed in children with DS, yet there are currently no standard interventions for children under 6. A number of research-based interventions exist in the literature, yet it is unknown how effective these are. What this study adds to existing knowledge This is the first systematic review that specifically and exclusively focuses on parent- and non-parent-mediated speech, language and communication interventions for children with DS between 0 and 6 years of age. It complements three existing recent reviews, each of which has a slightly different focus. The previously published reviews have covered only parent-mediated interventions, excluding interventions not mediated by parents, have reviewed interventions including children and adults, without any mention of what early interventions may be like or how effective these may be for young children with DS, have not always assessed risk of bias or have focused specifically on language interventions excluding those focusing on speech articulation or pre-linguistic skills. The findings from the current review suggest that interventions that have high dosage focus on language and communication training within a naturalistic setting and are co-delivered by parents and clinicians/researchers may have the potential to provide positive outcomes for children with Diwn syndrome from 0 to 6. We acknowledge that the current evidence base comes from studies with moderate to high risk of bias, hence our conclusions are not definitive. What are the potential or actual clinical implications of this work? Speech and language therapists will have synthesized information and a quick reference point on what type of interventions exist for children with DS under the age of 6, and evidence of which intervention approaches may be promising in terms of providing positive outcomes. However, it is acknowledged that, due to the limited number of studies and the moderate to high risk of bias inherent in the evidence, there is an urgent need for higher quality intervention studies in the field to build the evidence base.

Use of antioxidants supplementation on developmental outcomes in children with Down syndrome-A systematic review and meta-analyses

BACKGROUND

The background of this study is to evaluate the published literature on the use of antioxidants in improving developmental outcomes in children with DS.

METHODS

The systematic review included interventional studies (randomized controlled trials [RCTs] and quasi-RCTs [q-RCTs]) of children aged 0 to 18 years diagnosed with DS who received antioxidants to improve developmental outcomes. Studies were excluded if they were interventional studies with non-random allocation or lack of control group or non-interventional studies including observational studies, systematic and narrative review articles, editorials and commentaries. Studies were also excluded if data from participants with DS were included as part of a larger group of participants (e.g., children with intellectual disability) and the data could not be separated for subgroup analysis, or if outcomes did not assess developmental domains (e.g., reported biochemical markers only). The review included children with other conditions associated with developmental disability, only when data for children with DS were separately reported.

RESULTS

Eleven RCTs and q-RCTs fulfilled the eligibility criteria with 683 participants with Down syndrome ranging in age from newborns to 17 years. Nine studies did not show any statistically significant clinical benefit of using antioxidants. Three studies were included in a meta-analysis comparing changes in the effect sizes (post and pre-intervention) in Global Developmental Quotient (GDQ) between the intervention and control groups.

CONCLUSION

This review concludes that it is likely that the results are valid and suggest that the use of Antioxidant has no improvement in GDQ for children with DS. It is also unclear if any benefit exists for other developmental domains.

This Is My Baby Interview: An Adaptation to the Spanish Language and Culture

Evaluating the emotional state of parents is important for determining the intervention in the context of a family with a baby with Down syndrome. “This is my baby” is an interview that measures the acceptance, commitment and awareness of influence of parents towards their baby. The Spanish adaptation of this instrument helps to better understand the emotional state of parents of children with developmental disorders. A cross-cultural adaptation and reliability analysis was carried out. The results suggest that the Spanish version of the This Is My Baby interview is a reliable instrument to measure the levels of acceptance, commitment and awareness of influence of parents of an infant with Down syndrome.

Aging with Down Syndrome-Where Are We Now and Where Are We Going?

Down syndrome (DS) is a form of accelerated aging, and people with DS are highly prone to aging-related conditions that include vascular and neurological disorders. Due to the overexpression of several genes on Chromosome 21, for example genes encoding amyloid precursor protein (APP), superoxide dismutase (SOD), and some of the interferon receptors, those with DS exhibit significant accumulation of amyloid, phospho-tau, oxidative stress, neuronal loss, and neuroinflammation in the brain as they age. In this review, we will summarize the major strides in this research field that have been made in the last few decades, as well as discuss where we are now, and which research areas are considered essential for the field in the future. We examine the scientific history of DS bridging these milestones in research to current efforts in the field. We extrapolate on comorbidities associated with this phenotype and highlight clinical networks in the USA and Europe pursuing clinical research, concluding with funding efforts and recent recommendations to the NIH regarding DS research.

Developmental disabilities across the world: A scientometric review from 1936 to 2020

BACKGROUND

Developmental disabilities have been largely studied in the past years. Their etiological mechanisms have been underpinned to the interactions between genetic and environmental factors. These factors show variability across the world. Thus, it is important to understand where the set of knowledge obtained on developmental disabilities originates from and whether it is generalizable to low- and middle-income countries.

AIMS

This study aims to understand the origins of the available literature on developmental disabilities, keeping a focus on parenting, and identify the main trend of research.

METHODS AND PROCEDURE

A sample of 11,315 publications from 1936 to 2020 were collected from Scopus and a graphical country analysis was conducted. Furthermore, a qualitative approach enabled the clustering of references by keywords into four main areas: "Expression of the disorder", "Physiological Factors", "How it is studied" and "Environmental factors". For each area, a document co-citation analysis (DCA) on CiteSpace software was performed.

OUTCOMES AND RESULTS

Results highlight the leading role of North America in the study of developmental disabilities. Trends in the literature and the documents' scientific relevance are discussed in details.

CONCLUSIONS AND IMPLICATIONS

Results demand for investigation in different socio-economical settings to generalize our knowledge. What this paper adds? The current paper tries to provide insight into the origins of the literature on developmental disabilities with a focus on parenting, together with an analysis of the trends of research in the field. The paper consisted of a multi-disciplinary and multi-method review. In fact, the review tried to integrate the analysis of the relation between developmental disabilities with a closer look at the scientific contributions to the field across the world. Specifically, the paper integrates a total of 11,315 papers published on almost a century of research (from 1936 to 2020). An initial qualitative analysis on keywords was combined to a subsequent quantitative approach in order to maximize the comprehension of the impact of almost a century of scientific contributions. Specifically, documents were studied with temporal and structural metrics on a scientometric approach. This allowed the exploration of patterns within the literature available on Scopus in a quantitative way. This method not only assessed the importance of single documents within the network. As a matter of fact, the document co-citation analysis used on CiteSpace software provided insight into the relations existing between multiple documents in the field of research. As a result, the leading role of North America in the literature of developmental disabilities and parenting emerged. This was accompanied by the review of the main trends of research within the existing literature.

A Qualitative Evidence Synthesis of Parental Experiences and Perceptions of Parent-Child Interaction Therapy for Preschool Children With Communication Difficulties

Purpose Parent-child interaction therapy refers to a number of interventions mediated by trained parents to treat developmental difficulties, including speech, language, and communication. Understanding the experiences of parents who take part in parent-child interaction therapy is a key aspect of determining how this intervention can be implemented successfully. However, to date, there has been limited work on synthesizing parental views of this intervention. Method We used qualitative evidence synthesis that involved searching the literature for qualitative studies addressing the experiences and perceptions of parent-child interaction therapy for parents of preschool children with communication difficulties. We identified 27 studies (from 32 publications) and synthesized the data using thematic synthesis. We appraised the quality of included studies using Critical Appraisal Skills Programme (CASP) and assessed our confidence in the review findings using GRADE Confidence in the Evidence from Reviews of Qualitative research (CERQual). Results At the beginning of this intervention, parents may have competing demands and varied expectations about the intervention. Their engagement is facilitated when the intervention is tailored to their individual family, their preferences for learning, and when they have a trusting relationship with the clinician. At the end of the intervention, although most parents perceive an improvement in their child's communication and feel empowered to facilitate this, they have concerns about their child's future needs. Conclusions It is important that clinicians explore parents' readiness for this intervention by discussing their needs and preferences openly, and that they facilitate their engagement through a supportive relationship. They also need to consider how parents will transition out of the intervention and continue to support their child's language development.

EUROlinkCAT protocol for a European population-based data linkage study investigating the survival, morbidity and education of children with congenital anomalies

INTRODUCTION

Congenital anomalies (CAs) are a major cause of infant mortality, childhood morbidity and long-term disability. Over 130 000 children born in Europe every year will have a CA. This paper describes the EUROlinkCAT study, which is investigating the health and educational outcomes of children with CAs for the first 10 years of their lives.

METHODS AND ANALYSIS

EUROCAT is a European network of population-based registries for the epidemiological surveillance of CAs. EUROlinkCAT is using the EUROCAT infrastructure to support 22 EUROCAT registries in 14 countries to link their data on births with CAs to mortality, hospital discharge, prescription and educational databases. Once linked, each registry transforms their case data into a common data model (CDM) format and they are then supplied with common STATA syntax scripts to analyse their data. The resulting aggregate tables and analysis results are submitted to a central results repository (CRR) and meta-analyses are performed to summarise the results across all registries. The CRR currently contains data on 155 594 children with a CA followed up to age 10 from a population of 6 million births from 1995 to 2014.

ETHICS

The CA registries have the required ethics permissions for routine surveillance and transmission of anonymised data to the EUROCAT central database. Each registry is responsible for applying for and obtaining additional ethics and other permissions required for their participation in EUROlinkCAT.

DISSEMINATION

The CDM and associated documentation, including linkage and standardisation procedures, will be available post-EUROlinkCAT thus facilitating future local, national and European-level analyses to improve healthcare. Recommendations to improve the accuracy of routinely collected data will be made.Findings will provide evidence to inform parents, health professionals, public health authorities and national treatment guidelines to optimise diagnosis, prevention and treatment for these children with a view to reducing health inequalities in Europe.

A Meta-Analysis of Single-Case Research on Applied Behavior Analytic Interventions for People With Down Syndrome

This systematic review evaluates single-case research design studies investigating applied behavior analytic (ABA) interventions for people with Down syndrome (DS). One hundred twenty-five studies examining the efficacy of ABA interventions on increasing skills and/or decreasing challenging behaviors met inclusion criteria. The What Works Clearinghouse standards and Risk of Bias in N-of-1 Trials scale were used to analyze methodological characteristics, and Tau-U effect sizes were calculated. Results suggest the use of ABA-based interventions are promising for behavior change in people with DS. Thirty-six high-quality studies were identified and demonstrated a medium overall effect. A range of outcomes was targeted, primarily involving communication and challenging behavior. These outcomes will guide future research on ABA interventions and DS.

Stage 1 Registered Report: The experiences and perceptions of parent-child interaction therapy for parents of young children with communication difficulties: A qualitative evidence synthesis protocol

Background: Parent-child interaction therapy refers to a group of interventions mediated by trained parents to address areas of developmental difficulties in children. In the field of speech and language therapy it is used in early intervention for children with speech, language and communication difficulties. The intervention involves training parents and caregivers on the importance of responsivity and language input in daily interactions and coaches them on strategies to implement these with the children. As the success of the intervention is heavily influenced by caregiver engagement, understanding and acceptance, it is important to consider their views. However, to date there has been limited work on synthesising parental views of this intervention. Methods: This is a protocol for a qualitative evidence synthesis of peer-reviewed qualitative papers addressing the experiences and perceptions of parent-child interaction therapy for parents of children with communication difficulties. We will complete a systematic search of 11 databases, review the reference lists and complete a cited reference search of all included studies. Two authors will independently screen tests for inclusion, initially by title and abstract, with full-text screening as necessary. Thematic synthesis will be used for all included studies. We will appraise the quality of included studies using CASP and confidence in the review findings using GRADE CERQual. Discussion: As the views of parents are pivotal in the success of this intervention, the findings from this synthesis should  help to guide best practice and policy for the future implementation of parent child interaction therapy for children with communication difficulties..
