Qualitative Analysis of Parental Observations on Quality of Life in Australian Children with Down Syndrome

Perspectives on the essential skills of healthcare decision making in children and adolescents with intellectual disability

BACKGROUND

Involvement in healthcare decisions is associated with better health outcomes for patients. For children and adolescents with intellectual disability, parents and healthcare professionals need to balance listening to a child's wishes with the responsibility of keeping them safe. However, there is a scarcity of literature evaluating how to effectively involve them in decision making. In this context, we review the concept of health literacy, focusing on the skills of healthcare decision making for children and adolescents with intellectual disability.

METHODS

We describe the concept of health literacy and models explaining shared decision making (individuals and healthcare professionals collaborate in decision making process) and supported decision making (when a trusted person supports the individual to collaborate with the healthcare professional in the decision-making process), and a rapid review of the literature evaluating their efficacy. We discuss healthcare decision making for children and adolescents with intellectual disability in the context of relevant recommendations from the recent Disability Royal Commission into Violence, Abuse, Neglect, and Exploitation of People with Disability in Australia.

RESULTS

Health literacy skills enable individuals to access, understand, appraise, remember and use health information and services. Shared decision making has been described for children with chronic conditions and supported decision making for adults with intellectual disability. Decision-making contributes to how individuals appraise and use healthcare. The rapid review found very limited evidence of outcomes where children and adolescents with intellectual disability have been supported to contribute to their healthcare decisions. Recommendations from the Disability Royal Commission highlight current needs for greater efforts to support and build the capacity of individuals with disability to be involved in the decisions that affect their life, including healthcare decision making.

CONCLUSIONS

Existing rights frameworks and healthcare standards confirm the importance of providing all people with the opportunities to learn and practise health literacy skills including decision making. There is little literature examining interventions for healthcare decision making for children with intellectual disability. Childhood is a critical time for the development of skills and autonomy. Evidence for how children and adolescents with intellectual disability can learn and practice healthcare decision-making skills in preparation for adulthood is needed to reduce inequities in their autonomy.

Caregivers' concerns and supports needed to care for adults with Down syndrome

Research regarding caregivers for individuals with Down syndrome mainly focuses on outcomes for the pediatric population and not on the experience of caregivers themselves. Our objective was to understand caregiver-reported experiences and concerns for themselves and the individual they care for through a survey of caregivers of adults with Down syndrome. We conducted a survey of N = 438 caregivers of adults with Down syndrome and asked about the perspectives of the respondents surrounding caregiving and demographics. The most common concerns among caregivers were planning for future needs (72.1%) and what happens when they (the caregiver) are gone (68.3%). Concerns they had for the individual they cared for were employment (63.2%) and friendships/relationships (63.2%). We found no significant difference in responses based on caregiver education level. Our survey identified six themes for the feedback about what clinical and research professionals should know to better serve individuals with Down syndrome, their families, and those who support them. Many caregivers discussed topics including healthcare, coordination, competence, and ability. More efforts for research into the caregiver experience for adults with Down syndrome are needed.

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.

Quality of life in Down syndrome in Brazil: a cross-sectional study

BACKGROUND

 Down syndrome is the most commonly genetic cause of developmental delay and intellectual disability, affecting 1:700 live births. It is associated with heart disease and recurrent infections, among other complications that greatly impair the patient's quality of life.

OBJECTIVE

 To evaluate the major factors associated with quality of life in a cohort of patients with Down syndrome.

METHODS

 We assessed 1,187 patients with Down syndrome, older than 4 years old, with an adaptation of the Personal Outcomes Scale validated for Portuguese language, interviewing patients, parents, and caregivers.

RESULTS

 A bad quality of life was reported in 56.4% of the sample. The main factors associated with better quality of life were female sex, first medical visit before 4 months old, higher parental education, a professionally active mother, and prenatal care. The main factors associated with worse quality of life were family history of alcohol abuse and psychiatric disorders and comorbidity with autism and epilepsy.

CONCLUSION

 Clinical comorbidities such as autism and epilepsy carry a heavy burden among patients with Down syndrome, while factors related to family support, such as employment status and educational background of the parents, enhance quality of life. The factors associated with quality of life among patients with Down syndrome should be adequately evaluated in medical consultation and targeted in public health policies.

The Effect of Caregiver-Implemented Training on Augmentative Alternative Communication Use by Individuals with Rett Syndrome: Remote Coaching via Telehealth

Limited published literature exists demonstrating functional relations between idiosyncratic responses or augmentative alternative communication (AAC) and social reinforcement for individuals with Rett syndrome. In this study, six females with Rett syndrome ages 2-25 demonstrated requesting for preferred items using both idiosyncratic responses (e.g, looking, reaching) and AAC (e.g. single response microswitches). Researchers connected remotely via telehealth to coach caregivers to implement all sessions in home environments. Researchers individualized response prompt delays during AAC sessions (request/mand training) based on each participants' latency to respond during baseline. Implications for practice and directions for future research are discussed.

Healthcare and Behavior Changes for Adults With Down Syndrome 1-Year Into COVID-19

Individuals with Down syndrome (DS) have been disproportionately harmed by the COVID-19 pandemic and may have been more likely to have sacrificed opportunity and activity to avoid potential exposures. Our objective was to describe the experience one to one and half years into the COVID-19 pandemic for adults with DS, as reported by their caregivers in an online survey conducted between April 2021 and September of 2021. In our sample of 438 adults with DS, caregivers reported that adults with DS lost activities, struggled with employment, had negative behavioral changes, lost skills, and developed more mental health conditions. For adults with DS, one in five caregivers reported less healthcare usage, one in four reported delayed routine care, and 86.5% reported lost activities. As the pandemic continues, targeted support for adults with DS is needed to prevent further skill loss and mental health conditions.

Psychometric properties of QI-Disability in CDKL5 Deficiency Disorder: Establishing readiness for clinical trials

CDKL5 Deficiency Disorder (CDD) is a rare genetic disorder with symptoms of epilepsy, developmental impairments, and other comorbidities. Currently, there are no outcome measures for CDD with comprehensive evidence of validation. This study aimed to evaluate the psychometric properties of the Quality of Life Inventory-Disability (QI-Disability) in CDD. Quality of Life Inventory-Disability was administered to 152 parent caregivers registered with the International CDKL5 Disorder Database (ICDD). Confirmatory factor analysis was conducted and the goodness of fit of the factor structure was assessed. Fixed-effects linear regression models examined the responsiveness of QI-Disability to reported changes in child health. A subset of parent caregivers (n = 56) completed QI-Disability, as well as additional health-related questions, on two occasions separated by four weeks to evaluate test-retest reliability. Test-retest reliability was assessed using intra-class correlations (ICCs) calculated from QI-Disability scores. Based upon adjustments for changes in child health, ICCs were recalculated to estimate responsiveness to change. Confirmatory factor analysis, internal consistency, and divergent validity were mostly satisfactory, except divergent validity was not satisfactory for the Social Interactions and Independence domains. The Physical Health, Social Interactions, Leisure, and Total scores responded to changes in the child's Physical health, and the Negative Emotions and Leisure domains responded to changes in the child's behavior. Unadjusted and adjusted ICC values were above 0.8 for the Positive Emotions, Negative Emotions, Social Interactions, Leisure, Independence domains and Total score, and above 0.6 for the Physical Health domain. Findings suggest that QI-Disability is suitable to assess the quality of life of children and adults with CDD and could be of value for upcoming clinical trials.

Quality of Life Among Down Syndrome Patients With and Without Congenital Heart Disease at King Abdulaziz University Hospital, Jeddah, Saudi Arabia

Background Congenital heart diseases (CHD) are common in Down syndrome patients who will often have additional anomalies, in which the presence of them and their management are expected to impact their quality of life (QoL). There are limited studies trying to evaluate the impact of CHD on the QoL in children with Down syndrome. Methods The present study comprised 97 Down syndrome children. The children's parents responded to phone interviews filling out TNO-AZL (Netherlands Organisation for Applied Scientific Research Academic Medical Centre) Preschool Quality of Life (TAPQOL) and TNO-AZL Child Quality of Life Parent Form (TACQOL-PF) questionnaires. Children were divided into two groups according to their age: group A (one to five years) and group B (six to 15 years). The results were analyzed using Statistical Package for Social Sciences (SPSS) software, version 21 (IBM Corp., Armonk, NY). Results CHD negatively affected motor skills in younger but not older children. All other QoL-related parameters were unaffected by CHD. Conclusion Down syndrome children with CHD demonstrated similar QoL to Down syndrome children without CHD, with the exception of having a lower motor outcome as infants/toddlers. This difference improved with time and did not exist in older children.

Understanding quality of life in people with complex and multiple communicative disabilities: A narrative overview of the empirical research literature

The fundamental characteristics of quality of life (QoL) are considered the same for all people. However, the relative importance of QoL domains may vary for specific populations. No studies have focused on understanding QoL for people with intellectual disabilities with additional communicative disabilities (developmental language disorder or hearing impairment), who experience complex and multiple communicative disabilities (CMCD). This study provides a narrative overview of QoL domains and indicators for this population, highlighting the role of communication. The 16 selected studies proved to be heterogeneous in study design, objective and conceptualization of QoL. The eight domains of QoL by Schalock and Verdugo (2002) are recognized, but few studies specify the importance of communication related to QoL for people with CMCD. The current overview attempts to emphasize not only the indirect role of communication for every QoL domain, but also the importance of acknowledging communication as a prerequisite for QoL in general.

Parents' Experiences of Having a Child with Down Syndrome and Sleep Difficulties

OBJECTIVES

Sleep disorders are prevalent in children with Down Syndrome (DS). However, sleep treatment is not always readily accessed by this group. This study aims to understand families' experiences of having a child with DS and sleep difficulties, and in particular, their healthcare experiences, with the goal of informing practice improvements.

METHODS

We conducted semi-structured interviews with 34 parents (fathers n = 4 and mothers n = 30) with open-ended questions about parents' experiences of sleep, family dynamics, and healthcare. We operationalized a reflexive Thematic Analysis.

RESULTS

Parents normalized their experiences of having a child with DS and sleep problems. Parents acknowledged that sleep disruption has adverse and pervasive impacts on their wellbeing and family dynamics, but also found this difficult to identify as a health problem. They accepted sleep difficulties as a regular part of bringing up any child, particularly one with a disability. When they did seek treatment for their child's sleep difficulties, parents often reported encountering insensitive and inadequate care and described that, at times, healthcare professionals also normalized children's sleep difficulties, resulting in sub-optimal treatment. This included at times failure to refer to tertiary sleep medicine services when required.

CONCLUSIONS

Parents' and healthcare professionals' normalization of sleeping difficulties denies that they are both deleterious and modifiable. Practice implications include raising healthcare professionals' awareness of the importance of proactively addressing sleep, with sensitivity to families' normalization strategies, recognizing that families may require prompting to report concerns.

Quality of life beyond diagnosis in intellectual disability - Latent profiling

OBJECTIVE

To compare quality of life (QOL) across diagnoses associated with intellectual disability, construct QOL profiles and evaluate membership by diagnostic group, function and comorbidities.

METHOD

Primary caregivers of 526 children with intellectual disability (age 5-18 years) and a diagnosis of cerebral palsy, autism spectrum disorder, Down syndrome, CDKL5 deficiency disorder or Rett syndrome completed the Quality of Life Inventory-Disability (QI-Disability) questionnaire. Latent profile analysis of the QI-Disability domain scores was conducted.

RESULTS

The mean (SD) total QOL score was 67.8 (13.4), ranging from 60.3 (14.6) for CDD to 77.5 (11.7) for Down syndrome. Three classes describing domain scores were identified: Class 1 was characterised by higher domain scores overall but poorer negative emotions scores; Class 2 by average to high scores for most domains but low independence scores; and Class 3 was characterised by low positive emotions, social interaction, and leisure and the outdoors scores, and extremely low independence scores. The majority of individuals with autism spectrum disorder and Down syndrome belonged to Class 1 and the majority with CDKL5 deficiency disorder belonged to Class 3. Those with better functional abilities (verbal communication and independent walking were predominately members of Class 1 and those with frequent seizures were more often members of Class 2 and 3.

CONCLUSION

The profiles illustrated variation in QOL across a diverse group of children. QOL evaluations illustrate areas where interventions could improve QOL and provide advice to families as to where efforts may be best directed.

Devising a Missing Data Rule for a Quality of Life Questionnaire-A Simulation Study

OBJECTIVE

The aim of this study was to devise an evidence-based missing data rule for the Quality of Life Inventory-Disability (QI-Disability) questionnaire specifying how many missing items are permissible for domain and total scores to be calculated using simple imputation. We sought a straightforward rule that can be used in both research and clinical monitoring settings.

METHOD

A simulation study was conducted involving random selection of missing items from a complete data set of questionnaire responses. This comprised 520 children with intellectual disability from 5 diagnostic groups. We applied a simple imputation scheme, and the simulated distribution of errors induced by imputation was compared with the previously estimated standard error of measurement (SEM) for each domain.

RESULTS

Using a stringent criterion, which requires that the 95th percentile of absolute error be less than the SEM, 1 missing item should be permitted for 2 of the 6 QI-Disability subdomain scores to be calculated and 1 missing item per domain for the total score to be calculated. Other, less stringent criteria would allow up to 2 missing items per domain.

CONCLUSION

Empirical evidence about the impact of imputing missing questionnaire responses can be gathered using simulation methods applied to a complete data set. We recommend that such evidence be used in devising a rule that specifies how many items can be imputed for a valid score to be calculated.

Parental perspectives on the quality of life of children with Down syndrome

Down Syndrome (DS) is the most common chromosome abnormality and the most frequent cause of developmental delay/intellectual disabilities in children. Although the investigation of the quality of life (QoL) is crucial in children with DS, relatively poor attention has been paid to this topic. The current study aimed to evaluate parent-reported QoL in a group of children with DS and identify children's individual and clinical features associated with different levels of QoL. We included in the study 73 children with DS (5-12 years) and investigated the parent-reported levels of QoL by means of the Pediatric Quality of Life Inventory. Cognitive level and the presence of behavioral difficulties were also evaluated. The overall parent-reported QoL of children with DS was high; emotional functioning was the domain with the highest level of QoL. Moreover, parents perceived low levels of QoL in children who exhibited low IQ, worse analogical reasoning, worse adaptive skills, more frequent challenging behaviors, more ritualistic/sameness behavior and more autistic symptoms. No differences emerged for family variables, namely parental education and employment, between the two groups with high and low QoL, as perceived by parents. The understanding of cognitive and behavioral factors - such as analogical reasoning, socio-communication abilities and challenging behaviors - related with different degrees of QoL in children with DS is crucial for the development of effective strategies to promote the improvement of the QoL.

Comorbidities and quality of life in children with intellectual disability

BACKGROUND

Many children with intellectual disability live with medical comorbidities. This study examined the impacts of comorbidities on quality of life (QOL) of children with intellectual disabilities and whether impacts varied with caregiver perceptions that medical needs had been met.

METHODS

Primary caregivers of 447 children (aged 5-19 years) with an intellectual disability reported on their child's medical comorbidities and the extent to which they perceived their child's medical needs had been met in a cross-sectional observational study. The Quality of Life Inventory-Disability was used to measure QOL on a 100-point scale. Linear regression models including interaction terms were used to evaluate their associations.

RESULTS

Parent-reported recurrent child pain (-4.97, 95% CI -8.21, -1.72), night-time sleep disturbances (-4.98, 95% CI -7.23, -2.73), daytime somnolence (-8.71, 95% CI -11.30, -2.73), seizures that occurred at least weekly (-7.59, 95% CI -13.50, -1.68) and conservatively managed severe scoliosis (-7.39, 95% CI -12.97, -1.81) were negatively associated with child QOL. Despite the majority of parents (~70%) perceiving that their child's medical needs had been met to a great extent, this did not significantly moderate the association between any comorbidities and QOL.

CONCLUSIONS

Comorbidities were common and had marked associations with QOL. Evaluation and management of pain and sleep disturbance continue to be high priorities in improving QOL of young people with intellectual disabilities. Further research on the optimal methods of managing these comorbidities is warranted.

Care Coordination Needs of Families of Children with Down Syndrome: A Scoping Review to Inform Development of mHealth Applications for Families

Care coordination is a critical component of health management aimed at linking care providers and health-information-involved care management. Our intent in this scoping review was to identify care coordination needs of families of children with Down syndrome (DS) and the strategies they used to meet those needs, with the goal of contributing to the evidence base for developing interventions by using an mHealth application (mHealth apps) for these families. Using established guidelines for scoping reviews, we searched five databases, yielding 2149 articles. Following abstract and full-text review, we identified 38 articles meeting our inclusion criteria. Studies incorporated varied in regard to research designs, samples, measures, and analytic approaches, with only one testing an intervention by using mHealth apps. Across studies, data came from 4882 families. Common aspects of families' care coordination needs included communication and information needs and utilization of healthcare resources. Additional themes were identified related to individual, family, and healthcare contextual factors. Authors also reported families' recommendations for desirable characteristics of an mHealth apps that addressed the design of a personal health record, meeting age-specific information needs, and ensuring access to up-to-date information. These results will further the development of mHealth apps that are tailored to the needs of families with a child with DS.

The effect of functioning on Quality of Life Inventory-Disability measured quality of life is not mediated or moderated by parental psychological distress

PURPOSE

The measurement of quality of life (QOL) in children with intellectual disability often relies upon proxy report via caregivers. The current study investigated whether caregiver psychological distress mediates or moderates the effects of impairment on their ratings of QOL in children with intellectual disability.

METHODS

Caregivers of 447 children with an intellectual disability reported their child's day-to-day functioning, their own psychological distress using the Kessler Psychological Distress Scale, and the Quality of Life Inventory-Disability (QI-Disability), a measure of QOL for proxy report of a child's observable behaviours that indicate quality of life. Linear regression was used to assess the effects of the child's functional abilities on their QI-Disability score and causal mediation analysis to estimate the extent to which these effects were mediated by caregivers' psychological distress.

RESULTS

A minority of caregivers (n = 121, 27.1%) reported no psychological distress. Lower day-to-day functional abilities, such as being fully dependent on others to manage their personal needs were associated with lower total QOL scores. There was no significant mediation effect of caregiver psychological distress on the association between child functioning and total QOL scores. Moderation analyses revealed small and largely nonsignificant interaction coefficients, indicating that caregiver psychological distress did not influence the strength of the relationship between child functioning and total QOL scores.

CONCLUSION

Caregiver psychological distress did not mediate or moderate the relationship between the level of functional abilities and QOL in children with intellectual disability. QI-Disability measured observable child behaviours which may reduce the influence of caregiver factors on the accurate measure of QOL for children with intellectual disability.

Family Variables and Quality of Life in Children with Down Syndrome: A Scoping Review

The purpose of this scoping review was to identify the family and child quality of life variables that have been studied in relation to one another in children with Down syndrome, the frequency with which different relationships have been studied, and the extent to which family variables were the focus of the research aims. A literature search was conducted to find studies published between January 2007 and June 2018. The initial search yielded 2314 studies; of these, 43 were selected for a final review. Researchers most often addressed family resources and family problem-solving and coping concerning child personal development and physical well-being. Little attention to child emotional well-being was observed, with none considering family appraisal of child emotional well-being. The relationship between family variables and child QoL rarely was the primary focus of the study. Methodologically, most reviewed studies used cross-sectional designs, were conducted in North America and based on maternal report. From future research considering the issues found in this review, healthcare providers can obtain an in-depth understanding of relationships between children and family variables.

Functioning, participation, and quality of life in children with intellectual disability: an observational study

AIMS

To investigate associations between functioning, community participation, and quality of life (QoL) and identify whether participation mediates the effects of functioning on QoL.

METHOD

The caregivers of 435 children (211 females, 224 males; mean age 12y; SD 3y 11mo; age range 5-18y) with intellectual disability and autism spectrum disorder, cerebral palsy, Down syndrome, or Rett syndrome reported on their child's functioning (dependence for managing personal needs, mobility, communication, eye contact when speaking), frequency of participation, and QoL. Linear regression and mediation analyses were used to evaluate the relationships between child functioning, participation, and QoL.

RESULTS

Children with greater dependency for managing personal needs and limited eye contact when speaking experienced poorer QoL. Less impaired functioning was associated with more frequent participation, which, in turn, was associated with a 3-point gain in QoL for each additional point in frequency of participation (coefficient=2.67, 95% confidence interval 1.56-3.78). The effect of impaired functioning on QoL was partially mediated by participation in children with greater dependency in managing personal needs and those with mildly impaired communication.

INTERPRETATION

Greater levels of impairments with poorer functioning, notably a high level of dependence, were associated with poorer QoL. Poorer QoL can be partly explained by less frequent community participation.

Exploring quality of life in individuals with a severe developmental and epileptic encephalopathy, CDKL5 Deficiency Disorder

BACKGROUND

CDKL5 Deficiency Disorder (CDD) is a rare genetic disorder caused by a mutation in the cyclin-dependent kinase-like 5 (CDKL5) gene. It is now considered to be a developmental and epileptic encephalopathy because of the early onset of seizures in association with severe global delay. Other features include cortical visual impairment, sleep and gastro-intestinal problems. Progress in clinical understanding, especially regarding the spectrum of functional ability, seizure patterns, and other comorbidities was initially slow but accelerated in 2012 with the establishment of the International CDKL5 Database (ICDD). Our aim was to use this data source to investigate quality of life (QOL) and associated factors in this disorder.

METHOD

A follow-up questionnaire was administered in 2018 to parents of children registered with the ICDD who had a pathogenic CDKL5 variant. QOL was assessed using QI Disability, an instrument, specifically developed to measure total and specific domains of QOL (physical health, positive emotions, negative emotions, social interaction, leisure and the outdoors (leisure) and independence) in children with intellectual disability. Associations with functional abilities, physical health, mental health and family factors were investigated, initially using univariate analyses followed by multivariate analyses for each of these groups with a final composite model which included the important variables identified from previous models.

RESULTS

Questionnaires were returned by 129/160 families with a child aged >3 years. Functional impairment, including lack of ability to sit, use hands and communicate had the greatest adverse impact on QOL. There were also some relationships with major genotype groupings. Individuals using three or more anti-epileptic medications had poorer QOL than those on one or no medication, particularly in the physical health domain. There was also variation by geographical region with those living in North America typically having the best QOL and those living in middle or lower income countries poorer QOL.

CONCLUSION

Although lower functional abilities were associated with poorer quality of life further research is needed to understand how environmental supports might mitigate this deficit. Comprehensive care and support for both the child and family have important roles to play in helping families to thrive despite the severity of CDD.

Parent-Reported Contribution of Family Variables to the Quality of Life in Children with Down Syndrome: Report from an International Study

PURPOSE

The intent of this study was to determine parents' views of the contribution of family variables to the quality of life (QoL) of children with Down Syndrome (DS). Based on prior research, we hypothesized that parents would report that family variables reflecting positive aspects of family functioning contributed to better QoL; and family variables reflecting the negative aspects of family functioning contributed to poorer QoL.

DESIGN AND METHODS

A cross-sectional study was carried out. Invitation letters were sent to DS support groups. Upon agreement, the parents of the children were sent a link to an online survey that included a consent form, demographic questionnaire, and child and family measures.

RESULTS

Results demonstrated the contribution of family demands to children's interpersonal relations. Family appraisals concerning the child and the family's ability predicted the children's physical and material well-being, personal development, self-determination, social inclusion, interpersonal relations, and rights. Family problem-solving served as a prominent predictor for children's physical and emotional well-being, personal development, interpersonal relations, and rights. Also, family resources predicted various aspects of children's QoL including physical, emotional, and material well-being, self-determination, social inclusion, interpersonal relations, and rights.

CONCLUSION

Results confirmed the significant relationship between family and children's QoL variables. Family appraisal and family problem-solving were especially identified as significant predictors of children's QoL that can be targeted for family interventions, since the family variables are modifiable aspects of family life.

PRACTICE IMPLICATIONS

Nurses can use current findings to develop interventions to enhance QoL of children with DS and families.

Reliability of the Quality of Life Inventory-Disability Measure in Children with Intellectual Disability

OBJECTIVE

To assess responsiveness and reproducibility using the estimates of test-retest reliability for the Quality of Life Inventory-Disability (QI-Disability), accounting for changes in child health and parental stress.

METHOD

Quality of Life Inventory-Disability was administered twice over a 1-month period to a sample of 55 primary caregivers of children (aged 5-19 years) with intellectual disability. Caregivers also reported their child's physical and mental health and completed a 4-item Perceived Stress Scale to assess parental stress. Fixed-effects linear regression models examined responsiveness of QI-Disability to the reported change in child health and parental stress. Reliability was then assessed using intraclass correlations (ICCs) calculated from QI-Disability scores adjusted for changes in child health and parental stress.

RESULTS

Five of 7 unadjusted ICC values indicated at least moderate agreement (>0.70), and 2 values indicated fair agreement. After accounting for changes in child health and parental stress, adjusted ICC values showed substantial agreement for the total QI-Disability score and 4 domain scores (adjusted ICC ≥ 0.80). Adjusted ICC scores indicated moderate agreement for the Physical Health domain (adjusted ICC = 0.68) and fair agreement for the Positive Emotions domain (adjusted ICC = 0.58). Improvements in a child's physical health rating were associated with higher total, Physical Health, and Positive Emotion domain scores, whereas improvements in mental health were associated with higher total and Negative Emotions domain scores, indicating better quality of life. Changes in parental stress did not have a statistically significant relationship with quality of life.

CONCLUSION

Satisfactory test-retest reliability was shown. Preliminary evidence indicates that QI-Disability is responsive to changes in child health, but not to differing levels of parental stress.

Content validation of the Quality of Life Inventory-Disability

BACKGROUND

Focus is shifting to better understand the lived experiences of children with intellectual disability in relation to their quality of life (QOL). Yet no available QOL measures are grounded in the domains important for this population. We previously conducted qualitative parent caregiver interviews identifying QOL domains in children with intellectual disability to constitute a new measure of QOL. This study describes the content validity of the Quality of Life Inventory-Disability (QI-Disability), a parent-report measure developed for children with intellectual disability.

METHODS AND RESULTS

Questionnaire items were extracted from a qualitative dataset of 77 parent caregiver interviews. To establish content validation, a draft of QI-Disability was administered to 16 parent caregivers of children with intellectual disability (Down syndrome, Rett syndrome, cerebral palsy, or autism spectrum disorder). Parents participated in a cognitive interviewing procedure known as the "think-aloud" method. The process of item generation, cognitive debriefing, and refinement of QI-Disability prior to its pilot testing are described. A conceptual framework is presented.

CONCLUSIONS

Satisfactory content validity is reported, where ongoing consumer feedback shaped the dataset from which the final items were selected. Use of QI-Disability for children with intellectual disability will allow for greater insight into service utility and targeted intervention.

Using directed-content analysis to identify a framework for understanding quality of life in adults with Rett syndrome

Purpose: Rett syndrome (RTT) is a rare neurodevelopmental disorder mainly affecting females and is caused by a mutation in the MECP2 gene. Recent research identified the domains of quality of life (QOL) important for children with RTT but there has been no investigation of domains important for adults. This qualitative study explored QOL in adults with RTT and compared domains with those previously identified for children.Methods: The sample comprised parents and/or primary caregivers of 20 adults, aged 18-38 years, who were registered with the Australian Rett Syndrome Database. Semi-structured telephone interviews were conducted to investigate aspects of life that were observed to be satisfying or challenging. Data were analyzed using directed content analysis, based on existing QOL domains for children with RTT that related to health and wellbeing, daily activities, and community immersion and services.Results: Each of the domains identified for children with RTT was represented in the adult dataset, with no new domains emerging.Conclusion: This is the first study to identify QOL domains important for adults with RTT. Health and therapy needs are ongoing during adulthood but services may be limited. Findings will guide choice of an appropriate QOL measure for this group.IMPLICATIONS FOR REHABILITATIONKnowing the important domains of quality of life enables clinicians and service providers to systematically review and address key management issues.Despite a high level of dependency and sometimes poor health, parent caregivers perceive potential for strong quality of life in adulthood.Services that maintain functional skills and health throughout the lifespan are valued for their support of quality of life in adults with Rett syndrome.

Parent-reported health-related quality of life of children with Down syndrome: a descriptive study

AIM

To describe health-related quality of life of Australian children and adolescents with Down syndrome and compare it with norm-referenced data.

METHOD

A cross-sectional survey was conducted with parents of 75 children and adolescents (43 males, 32 females) with Down syndrome aged 5 to 18 years (mean age 13y 2mo, SD 4y 8mo). The proxy-report KIDSCREEN-27 questionnaire was administered and five dimensions of health-related quality of life were measured. Data were analysed descriptively and compared with normative data.

RESULTS

Total group mean scores for psychological well-being, autonomy and parent relation, and school environment dimensions were within normal threshold values, whereas mean scores for physical well-being, and social support and peers dimensions, were poorer. For participants with Down syndrome aged 8 to 18 years, the difference with normative data for proxy-reported physical well-being, psychological well-being, and social support and peers dimensions favoured typically developing children. Adolescents (13-18y) with Down syndrome scored poorer on all dimensions than children (5-12y) with Down syndrome.

INTERPRETATION

Our findings assist a better understanding of the lived experiences of children and adolescents with Down syndrome, as perceived by their parents, and suggest aspects of health that could be influenced to optimize their quality of life.

WHAT THIS PAPER ADDS

Proxy-reported psychological well-being and autonomy were within the normal range for children with Down syndrome. Physical well-being and social support scores were significantly lower than normative data. Proxy-reported scores for adolescents with Down syndrome were consistently poorer than for children with Down syndrome and the differences were clinically important.

Exploring quality of life of children with cerebral palsy and intellectual disability: What are the important domains of life?

BACKGROUND

Although it is estimated that half of all children with cerebral palsy also have comorbid intellectual disability, the domains of quality of life (QOL) important for these children are not well understood. The aim of this study was to identify important domains of QOL for these children and adolescents.

METHODS

Due to the children's communication impairments, qualitative semi-structured interviews were conducted with 18 parents. The children (9 males) had a median age of 12 (range 7 to 17) years at interview and nearly two thirds were classified as Gross Motor Function Classification System IV or V. A grounded theory approach was used to identify domains of QOL.

RESULTS

The 11 domains identified as important to QOL were physical health, body comfort, behaviour and emotion, communication, predictability and routine, movement and physical activity, nature and outdoors, variety of activity, independence and autonomy, social connectedness, and access to services.

CONCLUSIONS

The domains of QOL that emerged from this study will be useful for professionals who support children with cerebral palsy and their families. They will also be important for developing a QOL instrument essential for informing the development of interventions and their monitoring and evaluation.

Parent-observed thematic data on quality of life in children with autism spectrum disorder

Domains of quality of life in children with autism spectrum disorder have not previously been explored and there has been no quality of life measure developed for this population. Our study investigated parent observations to identify the domains important to children with autism spectrum disorder who also had an intellectual disability. In all, 21 parents (19 mothers, 2 fathers) of children with autism spectrum disorder (aged 6–17 years) participated in a qualitative study to discuss their child’s quality of life. Thematic analysis using a grounded theory framework was conducted and 10 domains emerged in relation to health and well-being, capacity to perform and develop skills in daily life, and connections with the community and environment. Unique aspects of quality of life included varying levels of social desire, consistency of routines, and time spent in nature and the outdoors, which are not comprehensively captured in existing measures. Parent observations provide an initial framework for understanding quality of life in autism spectrum disorder and support the development of a new measure for this population.

Health-Related Quality of Life in Individuals with Down Syndrome: Results from a Non-Interventional Longitudinal Multi-National Study

INTRODUCTION

To date, there is little research on health-related quality of life (HRQoL) in Down syndrome (DS), and existing research is variable with regard to reported HRQoL in DS. There are also no HRQoL measures developed specifically to be used with individuals with Down syndrome.

METHODS

A multi-national, longitudinal, 24-week non-interventional study was conducted in adolescents and adults with DS. HRQoL was assessed (n = 90) using the parent-report KIDSCREEN-27 questionnaire.

RESULTS

HRQoL domain scores were found to be similar to those in the KIDSCREEN-27 European normative group data set on the Physical Well-being, Psychological Well-being, Autonomy and Parent Relations domains. Compared with the normative data set, the adolescent participants with DS in the current study were found to have lower scores on the Social Support and Peers domain and higher scores than the normative group on the School Environment domain. The test-retest reliability of the KIDSCREEN-27 was also examined using the intraclass correlation coefficient (ICC) in a subgroup of stable participants. The KIDSCREEN-27 demonstrated poor-to-moderate test-retest reliability; however, test-retest reliability was assessed using a long time interval between assessment time points.

CONCLUSION

The findings of this study underline that further research is needed to better understand the nature of HRQoL in DS. Further research using a shorter time interval between assessment time points to examine test-retest reliability is also required.
