ABSTRACT

A 2003 survey revealed the scope of mothers' dissatisfaction with their postnatal support following a diagnosis of Down syndrome (DS). Substantial proportions of mothers reported that providers conveyed diagnoses with pity, emphasized negative aspects of DS, and neglected to provide adequate materials explaining DS. This study follows up on the 2003 survey by assessing whether parents' experiences have improved. Four DS nonprofit organizations, which participated in the original study, distributed a mixed-methods survey to families who have had children with DS between 2003 and 2022. Quantitative analysis assessed correlations among responses and differences between the 2003 and 2022 survey groups. Open-ended responses were qualitatively analyzed. Compared to the 2003 findings, parents' perceptions of their postnatal care have not improved (N = 89). Parents are increasingly likely to report that their providers pitied them, omitted positive aspects of DS, and provided insufficient materials describing DS. Substantial proportions of parents reported fear (77%) and anxiety (79%), only 24% described receiving adequate explanatory materials, and parents were 45% likelier to report that physicians discussed negative aspects of DS than positive aspects. Qualitatively, substantial numbers of parents recounted insensitive conduct by providers. These results suggest that despite interventions, parents' experiences of postnatal diagnoses of DS have not improved over time. Certain provider behaviors-such as describing positive aspects of DS and providing comprehensive explanatory materials-can reduce fear and anxiety, pointing to directions for reform.

ABSTRACT

OBJECTIVE: There is a general assumption that Muslim women refuse Down syndrome screening, and therefore, many health practitioners do not offer it or briefly discuss it with their participants. This study aims to objectively assess women's awareness, knowledge, and attitudes toward Down Syndrome screening (D.S.S) in a Muslim-majority population. METHODS: We conducted a cross-sectional study among attendees of antenatal clinics at a major university hospital in Saudi Arabia, aiming for a sample size of at least 385 Muslim women. A semi-structured questionnaire assessed awareness of different D.S.S. options and the source of that information (2 items), specific knowledge of D.S.S. (14 items), and attitudes (4 items). The knowledge and attitudes scores were calculated using a five-level agreement Likert-type scale. RESULTS: Among 434 participants, with an even distribution among all age groups and a majority of a college degree holder or higher (71%), 178 (41.0%) reported awareness of D.S.S. Factors associated with increased awareness were maternal age above 40 or those under 30, nulliparity, and extended family history of fetal congenital anomalies (P-value = 0.03,0.015, and 0.017, respectively). Recognized tests were ultrasound measurement of nuchal translucency (71.9%) and first-trimester serum screening (58.4%). The sources of knowledge were obstetricians (53.9%), followed by family and friends (27.0%). The overall mean ± SD knowledge score was 53.9 ± 8.7 out of 70, and the mean attitude score was 17.4 ± 2.9 out of 20. Having 1 or 2 children is associated with a higher knowledge score, and most participants who reported awareness of D.S.S. (51.7%) had a favorable attitude toward screening. CONCLUSION: Awareness of D.S.S. among Muslim women is associated with favorable attitudes towards testing, contradicting the general assumption and highlighting the need for systematic education to increase awareness and subsequent testing uptake.

ABSTRACT

There is convincing evidence that training spatial abilities leads to improved mathematics performance in typically developing (TD) children. However, a lack of information on mathematical development and spatial-mathematical associations in people with Down syndrome (DS) hinders the translation of these interventions. Here, we established developmental trajectories of mathematics and explored whether spatial ability predicts attainment on different mathematics measures in individuals with DS. Participants with DS (n = 36; ages 9-35 years) and TD children (n = 132; ages 4-11 years) completed three groups of tasks: spatial tasks assessing different subdomains of spatial thinking; mathematics tasks assessing early mathematics skills, mathematical reasoning, arithmetic, and geometry; and IQ tasks. The developmental trajectories of mathematics performance against mental age revealed similar starting points of the trajectories and similar rates of development for DS and TD groups. Furthermore, after controlling for verbal skills, spatial skills explained 5.8% to 18.1% of the variation in mathematical performance across different mathematics tasks, and the pattern of spatial-mathematical relations was similar for DS and mental age-matched TD groups. This shows that mathematical development in DS groups appears to mirror that in TD children, indicative of delay only. Strong spatial-mathematical relations were observed for individuals with DS, like those seen for TD participants. This is the vital preliminary knowledge needed to support the design and use of spatial intervention for improving mathematics in individuals with DS.

ABSTRACT

This article aims to advance knowledge related to the concept of the 'shame-blame complex' by analysing the accounts and experiences of parents with cognitively disabled children. It draws on 29 interviews with parents of children with Down syndrome and shadowing sessions with one family, carried out in Italy. Results show how the feeling of shame as a consequence of being associated with a disabled child is turned into blame for bad parenting. The sources of this blaming process are twofold: firstly, neoliberalism has disseminated an intensive parenting model based on the imperative of individual responsibility and risk avoidance. Secondly, ableism acts as a network of processes and beliefs that produce a particular kind of self and body as the perfect and complete human being. Participants have been held responsible for their children's condition because they avoided prenatal screening or continued a pregnancy after receiving a positive result. Consequently, parents' moral culpability for their children's diversity and their social marginalisation were enhanced. Although the interviewees resist the shame of being associated with a cognitively disabled child and the blame for bad parenting, they seem unable to escape from the grips of the shame-blame complex. The latter has structural and cultural underpinnings. In an age of 'neoliberal-ableism', this complex is indeed a powerful weapon to erode the rights of families with cognitively disabled members.

ABSTRACT

BACKGROUND: Spatial abilities are fundamental cognitive abilities, have direct applications in daily life, serve as a cognitive foundation for many other complex skills and are used in many specialty jobs. The current study aimed to systematically and comprehensively evaluate the spatial abilities of individuals with Down syndrome (DS) relative to mental ability-matched typically developing (TD) children based on Newcombe and Shipley's double-dimension theoretical framework for classifying spatial abilities. METHODS: Forty adolescents and young adults with DS and 40 TD children completed a nonverbal intelligence test (Raven's), two measures of static-extrinsic skills (water-level task and cart task), two measures of static-intrinsic skills (figure ground and form completion), two measures of dynamic-extrinsic skills (three mountains task and dog task) and two measures of dynamic-intrinsic spatial skills (mental rotation task and block design task). RESULTS: Participants with DS showed reduced performance on two dynamic-intrinsic tasks and one static-extrinsic task (i.e. cart task) relative to TD children. Performances were similar in two dynamic-extrinsic tasks and two static-intrinsic tasks. Analyses of composite accuracy for each spatial category further confirmed deficits in dynamic-intrinsic and static-extrinsic categories for people with DS relative to TD children. CONCLUSIONS: Our results showed an uneven profile of spatial abilities in people with DS relative to ability-matched TD children with particular weaknesses in comprehending and manipulating dynamic-intrinsic and static-extrinsic spatial relations. Furthermore, our research has important clinical implications for more targeted interventions to improve spatial abilities in people with DS.

ABSTRACT

According to a biopsychosocial framework, personal and environmental factors might be mediators or facilitators/barriers, respectively, to functioning. However, it is not known how these factors can impact independence in household chores in children/adolescents with Down syndrome (DS). This study explored whether and how personal/environmental factors are associated with the independence level in household chores of children/adolescents with DS in Brazil. Caregivers of twenty-eight children/adolescents with DS were interviewed using the CHORES and a standardized questionnaire about personal (child's age and sex) and environmental (socioeconomic level and maternal schooling) factors. Multiple linear regression analysis identified if/how these factors are associated with level of independence. For CHORES self-care and CHORES total, sex was a significant variable explaining 21.8% and 15.8%, respectively, of the variation in the outcomes. For the outcome CHORES family care none of the variables was significant. Female sex was associated with a lower need for assistance. We conclude that only the personal factor assessed related to female sex in children with DS was associated with the independence level in household chores. This finding highlights the importance of health care providers and families to encourage the independence in chores regardless of sex and promote opportunities for both boys and girls.

ABSTRACT

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

Background and Aim. Down syndrome (DS) is the most common reason for disabilities caused by genetic disorders. Due to the special nature of this disease and the special needs of children with Down syndrome, they are required to receive their families' support. Therefore, the recognition of their problems and needs and also the alternatives for resolving them and promoting their life quality are very useful. Also, since very limited qualitative studies have been conducted, it seems necessary to design a qualitative study. Method. This qualitative study was conducted by the content analysis method and through purposeful sampling method with the participation of 26 participants including 15 mothers, 6 fathers, 3 sisters, and 2 brothers of DS children in 2022-2023. The data were collected through semi-structured interviews. Findings. Using the content analysis method of Graneheim and Lundman (2004), the main theme was "Family self-supporting in protecting Down syndrome children." The subthemes were seven including "trying to find information-support resources," "Giving importance to child's health," "religious beliefs of the family," "child moral education, helping to child's relative self-support," "developing familial support," and "developing child's social interactions." Conclusion and Recommendations. The findings of this study showed that family is the main source of fulfilling the needs of children and their life challenges through using efficient self-support methods. This study introduced family self-support methods in terms of DS children in a way that other families can also manage the problems of their children more efficiently. The present study can be used by trustees of DS to support them and their families. Considering the existence of many problems in children with Down syndrome and the involvement of families, it is suggested that policymakers and community health managers provide the basis for receiving services and social support. For example, it is possible to strengthen the screening systems in the country to diagnose the disease on time and take quick action to solve this problem. Also, by increasing the health insurance coverage and fair distribution of the support resources needed by these people, it promoted the quality of life for them and their families. Also, health policymakers in Iran can take action to increase life expectancy and reduce deaths caused by DS by improving the equitable distribution of health resources and services. Also, public policies should enhance supportive intermediation for prevention and life quality promotion and also decrease health challenges. They are also supposed to lessen the costs of health care. Furthermore, to support social organizations, health service providers and researchers should consider the development of intermediations for the health enhancing and life quality promoting of DS children.

ABSTRACT

PURPOSE: Down syndrome (DS) is a common abnormality associated with anorectal malformation (ARM) and Hirschsprung's disease (HD). However, quality of life (QOL) in ARM and HD patients with DS is under-researched. This study compares parent-reported QOL and bowel function in ARM and HD patients with DS to those without. METHODS: Between December 2020 to February 2023, parents of ARM and HD patients with and without DS aged 3-17 years who had undergone surgery > 12 months prior at four tertiary referral centers were recruited. We used the Pediatric Quality of Life Inventory™ (PedsQL™) Generic Core Scales, General Well-Being (GWB) Scale and Family Impact (FI) Module questionnaires, and the Rintala bowel function score (BFS). RESULTS: There were 101 ARM, 9 (8.9%) of whom had DS; and 87 HD, of whom 6 (6.9%) had DS. Parent-reported Core scores in ARM and HD with DS were comparable to those without DS. However, ARM and HD with DS had worse scores in the FI Module and bowel function than those without DS. CONCLUSION: Although parent-reported QOL in ARM and HD with DS is similar to those without DS, family impact and BFS are worse. Our findings are limited by small sample size in proportion of DS patients.

ABSTRACT

INTRODUCTION: Generally, mothers provide the majority of caring for children who have Down syndrome. They pose challenges not only with regard to the acceptability of the child situation but also with regard to the provision of care for children with DS. AIM: To explore the experiences of mothers parenting children with DS in Indonesia, to give a better understanding of their needs, which is necessary for the delivery of treatment. METHODS: A descriptive qualitative research with content analysis was used. Study participants (15 mothers) were purposively sampled from attendees of a State Special School for students with disabilities. Data was collected via semi-structure interviews and were audio recorded. Participant's statements underwent content analysis, and the principle of trustworthiness was subsequently applied. RESULTS: Five main themes describing participants' experiences were identified: (1) parenting experiences - the impacts, (2) special needs, (3) parenting barriers, (4) parenting facilitators, and (5) mothers' expectations. CONCLUSIONS: The study findings showed that the mothers viewed their situation in both positive and negative ways. Despite the limited sample size in this exploratory study, the results offer new insights into raising a child with DS in a particular cultural setting. IMPLICATIONS FOR PRACTICE: This study offers important information to families and healthcare providers to improve awareness of the disorder and its appropriate management methods. It is important that an exploration of the experiences of mothers will provide healthcare professionals and families with an understanding of the situation. This understanding is essential for the effective management and delivery of treatment.

ABSTRACT

Our main objective was to analyze the role of imageability in relation to the age of acquisition (AoA) of nouns and verbs in Spanish-speaking children with Down syndrome (DS) and their peers with typical development (TD). The AoA of nouns and verbs was determined using the MacArthur-Bates CDIs adapted to the profile of children with DS. The AoA was analyzed using a linear mixed-effect model, including factors of imageability, group, and word class, and controlling for word frequency and word length. This analysis showed that high imaginable and short words were acquired early. Children with DS acquired the words later than TD peers. An interaction between imageability and group indicated that the effect of imageability was greater in the DS group. We discuss this effect considering DS children's phonological memory difficulties. The overall results confirm the role that imageability and word length play in lexical acquisition, an effect that goes beyond word class.

ABSTRACT

INTRODUCTION: Narratives are enriched by taking the perspective of the protagonists, which can be expressed using reported speech. Nevertheless, the use of reported speech is unaddressed internationally among individuals with Down syndrome. METHOD: Narratives of 28 children and adolescents with Down syndrome were collected using a non-verbal picture book. Occurrence and forms of reported speech were analysed and compared to typically-developing children (TD; n = 33). RESULTS: Participants from both populations use reported speech in their narratives with a comparable proportion. Nevertheless, differences appear concerning forms of direct speech with persons with Down syndrome using more free direct speech than TD-children. DISCUSSION: The results suggest that children and adolescents are able to implement the use of reported speech regardless of their syntactic impairments. Concerning the occurring forms of direct speech, the results might point to cognitive impairments that manifest in limited consideration of the interlocutor's knowledge.

ABSTRACT

BACKGROUND: Parents' conceptualizations of adulthood for their emerging adults with Down syndrome have the potential to impact the transition planning process as families prepare for life after graduation. AIMS: This study aimed to explore parent perceptions of the meaning of adulthood for their emerging adults with Down syndrome. METHODS: In this qualitative study, we interviewed 11 parents of emerging adults with Down syndrome using phenomenological methodology and analysed these data using thematic analysis. RESULTS: Three topics emerged: (1) Parents' constructions of the meaning of adulthood; (2) Parents' perceptions about the transition to adulthood; and (3) Parents' perceptions of current adult life skills. Ten themes arose out of these topics. CONCLUSIONS: Parents expressed ambivalence about the meaning of adulthood for their emerging adults with Down syndrome, sharing that in some ways they were adults and in others they were not. The meaning of adulthood was closely tied to obtained skills, particularly those related to personal safety.

ABSTRACT

Several non-verbal cognitive and behavioral tests have been developed to assess learning deficits in humans with Down syndrome (DS). Here we used rodent touchscreen paradigms in adult male mice to investigate visual discrimination (VD) learning and inhibitory control in the Dp(16)1/Yey (C57BL/6J genetic background), Ts65Dn (mixed B6 X C3H genetic background) and Ts1Cje (C57BL/6J genetic background) mouse models of DS. Dp(16)1/Yey and Ts1Cje models did not exhibit motivation or learning deficits during early pre-training, however, Ts1Cje mice showed a significant learning delay after the introduction of the incorrect stimulus (late pre-training), suggesting prefrontal cortex defects in this model. Dp(16)1/Yey and Ts1Cje mice display learning deficits in VD but these deficits were more pronounced in the Dp(16)1/Yey model. Both models also exhibited compulsive behavior and abnormal cortical inhibitory control during Extinction compared to WT littermates. Finally, Ts65Dn mice outperformed WT littermates in pre-training stages by initiating a significantly higher number of trials due to their hyperactive behavior. Both Ts65Dn and WT littermates showed poor performance during late pre-training and were not tested in VD. These studies demonstrate significant learning deficits and compulsive behavior in the Ts1Cje and Dp(16)1/Yey mouse models of DS. They also demonstrate that the mouse genetic background (C57BL/6J vs. mixed B6 X C3H) and the absence of hyperactive behavior are key determinants of successful learning in touchscreen behavioral testing. These data will be used to select the mouse model that best mimics cognitive deficits in humans with DS and evaluate the effects of future therapeutic interventions.

ABSTRACT

Studies in the neurotypical population have demonstrated that personal social networks can mitigate cognitive decline and the development of Alzheimer disease. To assess whether these benefits can also be extended to people with Down syndrome (DS), we studied whether and how personal networks can be measured in this population. We adapted a personal networks instrument previously created, validated, and implemented for the neurotypical population. We created two versions of the survey: one for participants with DS, ages 25 and older, and another for their study partners, who spent a minimum of 10 h/wk in a caregiver role. Participants with DS gave concordant data to those of study partners. Their personal networks included a median network size of 7.50, density 0.80, constraint 46.00, and effective size 3.07. Personal networks were composed of 50% kin, 80% who live within 15 miles, and 80% who eat a healthy diet. In this proof-of-principle study, we demonstrated that the personal networks of people with DS can be quantitatively analyzed, with no statistical difference between self-report and parent-proxy report. Future research efforts can now evaluate interventions to enhance personal networks for preventing Alzheimer disease in this population.

ABSTRACT

Down syndrome (DS) has a unique medical and psychological profile. To date, few studies have asked individuals with DS about their views of health, and fewer have explored the impact of COVID-19 on the health of individuals with DS and their families. We used a mixed methods approach including two studies on the health of individuals with DS and their parents conducted during the COVID-19 pandemic: (1) eight virtual focus groups, comprised of 20 parents and 8 individuals with DS to obtain participants' views of health, and (2) a 20-item questionnaire on health care experience of patients with DS who are African American or come from primarily Spanish-speaking homes. Focus group transcripts were coded using a hybrid inductive/deductive framework and thematically analyzed using the Framework Method. This questionnaire included questions regarding the impact of COVID-19 on caregivers and their loved ones with DS; responses to these questions were summarized using descriptive statistics. Individuals with DS discussed the impact of the COVID-19 pandemic on their physical and social health including masking, online learning, and online communication with friends and family. Parents of individuals with DS discussed how the COVID-19 pandemic negatively impacted their child's physical, social, and mental health, as a result of virtual schooling and decreased socialization. There were unexpected positives of the pandemic such as improved hygiene and eased scheduling with telehealth visits. Caregivers noted COVID-19 impacted their own anxiety, employment, and other domains that have potential ripple effects on the health of their children. The COVID-19 pandemic had a pervasive impact on the mental health and wellness of caregivers as well as the physical, social, and mental health of individuals with DS.

ABSTRACT

BACKGROUND: Accurate measurement of cognitive skills is necessary to advance both developmental and intervention science for individuals with Down syndrome (DS). This study evaluated the feasibility, developmental sensitivity and preliminary reliability of a reverse categorisation measure designed to assess cognitive flexibility in young children with DS. METHODS: Seventy-two children with DS ages 2.5-8 years completed an adapted version of a reverse categorisation task. Twenty-eight of the participants were assessed again 2 weeks later for retest reliability. RESULTS: This adapted measure demonstrated adequate feasibility and developmental sensitivity, and preliminary evidence for test-retest reliability when administered to children with DS in this age range. CONCLUSIONS: This adapted reverse categorisation measure may be useful for future developmental and treatment studies that target early foundations of cognitive flexibility in young children with DS. Additional recommendations for use of this measure are discussed.

ABSTRACT

BACKGROUND: Down syndrome (DS) has a unique medical and psychological profile that could impact how health is defined on three dimensions: physical, social and mental well-being. METHODS: In 2021, we presented our proposed conceptual model to three expert panels, four focus groups of parents of individuals with DS age 0-21 years and four focus groups of individuals with DS age 13-21 years through videoconferencing technology. Participants gave feedback and discussed the concept of health in DS. RESULTS: Feedback from participants resulted in iterative refinement of our model, retaining the three dimensions of health, and modifying constructs within those dimensions. Experts and parents agreed that individuals with DS have unique health concerns that necessitate the creation and validation of a syndrome-specific health model. We present key themes that we identified and a final conceptual model of health for individuals with DS. CONCLUSION: Health in DS is a multi-dimensional, multi-construct model focused on relevant constructs of causal and effect indicators. This conceptual model can be used in future research to develop a syndrome-specific measure of health status.

ABSTRACT

BACKGROUND: Inhibitory control measures have been commonly used when assessing individuals with Down syndrome. However, minimal attention has been devoted to evaluating the appropriateness of specific assessments for use in this population, potentially leading to erroneous conclusions. This study aimed to examine the psychometric properties of measures of inhibitory control among youth with Down syndrome. We sought to examine the feasibility, presence of floor or practice effects, test-retest reliability, convergent validity and correlations with broader developmental domains of a set of inhibitory control tasks. METHODS: A sample of 97 youth with Down syndrome aged 6 to 17 years old participated in verbal and visuospatial tasks of inhibitory control including the Cat/dog Stroop, Neuropsychological Assessment Second Edition (NEPSY-II) Statue, National Institutes of Health (NIH) Toolbox Cognition Battery (TCB) Flanker, Leiter-3 Attention Sustained, and the Test of Attentional Performance for Children (KiTAP) Go/No-go and Distractibility subtests. Youth also completed standardised assessments of cognition and language, and caregivers completed rating scales. Psychometric properties on the tasks of inhibitory control were evaluated against a priori criteria. RESULTS: Apart from demonstrating negligible practice effects, adequate psychometric properties were not observed for any inhibitory control measure within the current sample's age range. One task with low working memory demands (NEPSY-II Statue) generally had better psychometric properties than the other tasks assessed. Subgroups of participants with an IQ greater than 30 and age more than 8 years were shown to be more likely to be able to complete the inhibition tasks. CONCLUSIONS: Findings suggest better feasibility for analogue tasks rather than computerised assessments of inhibitory control. Given the weak psychometrics of several common measures, future studies are required to evaluate other inhibitory control measures, specifically those with reduced working memory demands for youth with Down syndrome. Recommendations for use of the inhibitory control tasks among youth with Down syndrome are provided.

ABSTRACT

BACKGROUND: Down syndrome has a unique medical and psychological profile. To date, few studies have asked individuals with Down syndrome about their views of health. METHODS: Eight focus groups of 20 parents and 8 individuals with Down syndrome, were conducted virtually via videoconferencing to obtain participants' views of health indicators. Focus group moderators employed some modifications for individuals with Down syndrome, including simplified language and use of graphics. Transcripts were coded using a hybrid inductive/deductive framework and thematically analysed using the Framework Method. RESULTS: We describe lessons learned in conducting virtual focus groups of individuals with Down syndrome and their parents. Individuals with Down syndrome could describe their views of health indicators and identified many of the same topics as their parents. Both groups discussed physical, mental, and social health components. However, people with Down syndrome gave a more restricted range of examples, but with different nuances than parents. CONCLUSION: Partcipants discussed physical, social, and mental well-being components of health in Down syndrome. Interviewing individuals with Down syndrome in virtual focus groups with appropriate modifications added important self-report health information.
