Child characteristics associated with child quality of life and parenting stress in Angelman syndrome. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2024; 68:248-263. [PMID: 38009976 DOI: 10.1111/jir.13106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 10/23/2023] [Accepted: 10/24/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND Angelman syndrome (AS) is a rare neurodevelopmental disorder characterised by severe intellectual disability, movement disorder, epilepsy, sleeping problems, and behavioural issues. Little is known on child health-related quality of life (HRQoL) in AS. AS family studies have reported elevated parenting stress and a high impact of the child's syndrome on the parent. It is unclear which factors influence child HRQoL and parenting stress/impact in AS. METHODS We collected data prospectively through standardised clinical assessments of children with AS at the ENCORE Expertise centre for Angelman Syndrome at the Erasmus MC Sophia Children's Hospital. A linear regression analysis was conducted for the following outcome variables: (1) child HRQoL (Infant and Toddler Quality of Life Questionnaire); (2) the impact of the child's syndrome on the parent (Infant and Toddler Quality of Life Questionnaire); and (3) parenting stress (Parenting Stress Index). Predictor variables were child genotype, epilepsy, sleeping problems (Sleep Disturbance Scale for Children), cognitive developmental level (Bayley Cognition Scale), autistic features (Autism Diagnostic Observation Schedule) and emotional/behavioural problems (Child Behaviour Checklist). Covariates were sex, age and socio-economic status. RESULTS The study sample consisted of 73 children with AS, mean age = 9.1 years, range = 2-18 years. Emotional/behavioural problems were the strongest significant predictor of lowered child HRQoL. Internalising problems were driving this effect. In addition, having the deletion genotype and higher age was related to lower child HRQoL. Sleeping problems were related to a higher impact of the child's syndrome on the parent. Finally, emotional/behavioural problems were associated with higher parenting stress. Cognitive developmental level, autistic features and epilepsy were not a significant predictor of child HRQoL and parenting stress/impact. CONCLUSIONS These results suggest that interventions aimed at increasing child HRQoL and decreasing parenting stress/impact in AS should focus on child emotional/behavioural problems and sleeping problems, using a family-centred approach.

Abstract
Daily experiences of mothers caring for children with Prader-Willi syndrome (PWS) are largely unknown and unvoiced. Knowledge of PWS has generally focused on pathology of the disorder. This emphasis overlooks the challenging moments of everyday life caring for children with PWS. Storied accounts of mothers caring for children with PWS offer expanded narratives to medicalized descriptions of experience. An understanding of everyday challenges in managing physical and mental health issues of PWS including hyperphagia and anxiety may create shifts in social and clinical perspectives. This understanding could improve practices in health and social care for families with PWS. This narrative inquiry studied everyday experience using storied accounts. Participants were mothers caring for children aged 3-17 years with genetically confirmed PWS who were experiencing hyperphagia. Four participants were recruited, and each interviewed 8-12 times over 12 months. Field texts and narrative accounts were co-composed through a collaborative process of analysis. Engaging with participants' day-to-day experiences offered insights into their work of nurturing, caring, and contributing to the care of a child with PWS. Narrative threads focused on complexity and rarity and include the desire to be normal, how ordinary becomes extraordinary, isolation, behaviors and normative standards, and alternative stories of mothering. Recommendations for practice and policy include (a) challenges of mothering a child with complexity, (b) moving beyond functionality and impairment to participation and quality of life, (c) re-storying narratives and supports for families, and (d) engaging with mothers to determine care priorities.

Abstract
Objective: Prader−Willi (PWS; OMIM#176270) syndrome is a clinically distinct genetic disorder, caused by an abnormality in the 15q11-q13 region, referred to as the critical region. One of the most popular concepts existing in modern sciences, not only within psychology, but also in the aspect of all sciences that are related to human life and its course, is the quality of life (QoL). Though it is known that health-related quality of life in children with PWS can be reduced, less is understood about the impact on the family. We aimed to identify factors related to the quality of life of children with PWS and the impact of the disease on family functioning. Methods: A cross-sectional questionnaire survey. The subjects were 46 parents of children with PWS. The Computer Assisted Self-Interviewing (CASI) method was used; the Paediatric Quality of Life Inventory and the PedsQL Family Impact Module. Results: The PedsQL mean score was 49.0; (min−max: 5.6−90.8; SD = 16.8), with the highest scores in the Emotional Functioning (EF) (EF; 55.9; min−max: 5.0−100.0; SD = 22.0), and the lowest in the Social Functioning (SF) (SF; 42.7; min−max: 5.0−85.0; SD = 18.7) 56.4 (SD ± 14.7). The child’s age does not affect the quality of life, there were no statistically significant (p > 0.05). families have difficulties in performing daily activities (total score 27.6; SD 16.7), support family functioning (total score 28.9; SD 18.8) and effects physical domain (total score 27.7; SD 15.7). Conclusion: Research on the QoL of patients with PWS and their families is very important in order to assess the QoL, but also to provide the perspective of an active change in the perspective of a better treatment process, rehabilitation and communication in society.

Abstract
BACKGROUND Angelman syndrome (AS) is a rare genetic condition characterized by global developmental delay, including severe intellectual disability. The parents of persons with AS experience increased stress, anxiety, and depression. This impacts parents' career choices and productivity. OBJECTIVE To estimate, for the first time, the total productivity lost by the parents of persons with AS over a 10-year period in Australia and the corresponding cost to society. METHODS A cost-of-illness model with simulated follow-up over a 10-year period was developed, with 2019 as the baseline year, facilitated by a Markov chain of life tables. The prevalence of persons with AS and their parents, the productivity-adjusted life years (PALYs) lost by parents, and the cost to society were estimated. Key data were obtained from a prospective cohort of AS families, peer-reviewed literature, and publicly available sources. RESULTS The base-case productivity burden borne by the estimated 330 living parents of the 428 prevalent persons with AS totaled AUD$45.30 million, corresponding to a loss of 38.42% of PALYs per parent. CONCLUSIONS Caring for a child with AS has a significant impact on the productivity of affected parents, with a large associated impact on the broader Australian economy.

Abstract
OBJECTIVES Young children with Angelman syndrome have significant delays in expressive communication. Parents of children with Angelman syndrome require training to support their child's communication development. Unfortunately, parent training focused on the needs of families of children with rare genetic syndromes is unavailable to many families. The purpose of this study was to evaluate a telehealth parent training program on naturalistic communication intervention for young children with Angelman syndrome. METHODS Using two single-case multiple baseline designs across a total of six parent-child dyads, we evaluated the effects of a telehealth parent training program on parent implementation fidelity of a naturalistic communication intervention, child communication, and child engagement. RESULTS With the telehealth parent training program, parent implementation fidelity of naturalistic communication intervention improved, maintained and generalized to untrained home routines. Small effects on child communication and engagement were observed during the program. CONCLUSIONS Parents of children with Angelman syndrome were successfully taught via telehealth to implement a naturalistic communication intervention with their child at home. Additional research is needed to promote positive child communication outcomes through parent-mediated intervention.

Abstract
OBJECTIVES Developmental and epileptic encephalopathies (DEEs) are rare neurodevelopmental disorders characterized by early-onset seizures and numerous comorbidities. Due to the complex requirements for the care of a child with a DEE, these disorders would be expected to impact health-related quality of life (HRQL) for caregivers as well as for patients. The objective of this literature review was to describe the impact of DEEs on the HRQL, emotional wellbeing, and usual activities (social, work, relationships, etc.) of caregivers, including the wider impact on other family members such as siblings. METHODS A literature search was conducted in May 2020 using MEDLINE® and Embase® databases. Quantitative and qualitative studies were identified using search terms related to family, disease type (including >20 specific DEEs), and quality of life/methodology. Each study was assessed for relevance and was graded using customized critical appraisal criteria. Findings from studies that were given the highest quality ratings were summarized and used to develop a conceptual model to illustrate the complex impact of DEEs on caregiver HRQL. RESULTS Sixty-seven relevant studies were identified, of which 39 (27 quantitative, 12 qualitative) met the highest appraisal criteria. The studies recruited caregivers of patients with one of eight individual DEEs, or pediatric intractable or refractory epilepsy. Most studies reported negative impacts on HRQL and emotional wellbeing in caregivers. The wide-ranging impact of a DEE was highlighted by reports of negative effects on caregivers' physical health, daily activities, relationships, social activities, leisure time, work, and productivity. Factors that influenced the perceived impact included demographic characteristics (e.g., child's age, living arrangements, family income) and clinical factors (e.g., feeding or sleep difficulties, disease severity). Few studies evaluated the impact on siblings. CONCLUSIONS There is evidence that DEEs can impact HRQL and emotional wellbeing and can limit usual activities for the primary caregiver and their wider family. However, no research was identified regarding many individual DEEs, and only limited research assessed the impact on different family members with most studies focusing on mothers. Further research is required to understand the influence of certain factors such as the age of the patient, disease severity, and seizures on caregiver burden. Furthermore, the review highlighted the lack of appropriate measurement tools to assess caregiver HRQL in this population.

Abstract
Prader-Willi syndrome (PWS) is a rare genetic disorder characterised by neurodevelopmental delays, hyperphagia, difficulties with social communication and challenging behaviours. Individuals require intensive supervision from caregivers which may negatively affect caregiver quality of life. This study used data collected in the Australasian PWS Registry (n = 50, mean age 11.2 years) to evaluate associations between child behaviours and caregiver mental well-being. Symptoms of sleep-related breathing disorder, child depression and social difficulties were associated with poorer caregiver mental and physical well-being. Growth hormone therapy use was associated with better caregiver mental and physical well-being. Optimising management of problematic behaviours and sleep disturbances have the potential to support caregivers who are the most vital network of support for individuals affected by PWS.

Abstract
Angelman syndrome (AS) is a complex, heterogeneous, and life-long neurodevelopmental disorder. Despite the considerable impact on individuals and caregivers, no disease-modifying treatments are available. To support holistic clinical management and the development of AS-specific outcome measures for clinical studies, we conducted primary and secondary research identifying the impact of symptoms on individuals with AS and their unmet need. This qualitative research adopted a rigorous step-wise approach, aggregating information from published literature, then evaluating it via disease concept elicitation interviews with clinical experts and caregivers. We found that the AS-defining concepts most relevant for treatment included: impaired expressive communication, seizures, maladaptive behavior, cognitive impairment, motor function difficulties, sleep disturbance, and limited self-care abilities. We highlight the relevance of age in experiencing these key AS concepts, and the difference between the perceptions of clinicians and caregivers towards the syndrome. Finally, we outline the impact of AS on individuals, caregivers, and families.

Abstract
BACKGROUND As life expectancy for people with an intellectual disability increases, there is a growing cohort of older father carers. This study aimed to gain a more in-depth understanding of older father carers' experiences of parenting. METHODS Semi-structured interviews were conducted with 7 older fathers (M = 63.9 years) and analysed using constructivist grounded theory. RESULTS Three conceptual categories were identified. "Wearing different hats: how fathers' sense of identity had altered over the years. "Family comes first": importance placed on the family unit. "Getting on in years": the challenges faced by ageing fathers parenting their son/daughter. CONCLUSIONS Fathers re-evaluated their priorities and found a new identity in their parenting role, although they continued to see themselves as secondary carers. Fathers worried about the future as their health declined but drew strength from the benefits they had derived and the challenges that they had overcome to do their best for their son/daughter and their family.

Abstract
Prader-Willi syndrome (PWS) is a rare genetic condition with multi-system involvement. The literature was reviewed to describe neurodevelopment and the behavioural phenotype, endocrine and metabolic disorders and respiratory and sleep functioning. Implications for child and family quality of life were explored. Challenging behaviours contribute to poorer well-being and quality of life for both the child and caregiver. Recent evidence indicates healthy outcomes of weight and height can be achieved with growth hormone therapy and dietary restriction and should be the current target for all individuals with PWS. Gaps in the literature included therapies to manage challenging behaviours, as well as understanding the effects of growth hormone on respiratory and sleep function. New knowledge regarding the transition of children and families from schooling and paediatric health services to employment, accommodation and adult health services is also needed. Developing a national population-based registry could address these knowledge gaps and inform advocacy for support services that improve the well-being of individuals with PWS and their families.

[PMID: 29255649 PMCID: PMC5732539 DOI: 10.7717/peerj.4097] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2017] [Accepted: 11/04/2017] [Indexed: 12/21/2022] Open
Abstract
Background Prader-Willi syndrome (PWS) is a complex, multisystem genetic disorder characterized by a variety of physical, cognitive, and behavioral impairments. PWS is a unique sarcopenia model characterized by an abnormal increase in body fat mass and a decrease in muscle mass that predisposes patients to reduced physical activity, functional limitations, and disability. These manifestations may require both symptomatic and supportive management, thus negatively influencing their lifelong family caregiver’s quality of life. The aim of this study was to examine the functional motor performance of adults with PWS in Taiwan and to measure the quality of life of their primary family caregivers. Methods The functional motor tests consisted of the following: (1) 30-s sit-to-stand test, (2) timed up-and-go test, (3) hand grip and lateral pinch strength tests, and (4) Berg Balance Scale. The World Health Organization Quality of Life-short form (WHOQOL-BREF) and the Short-Form 36 Health Survey Questionnaire (SF-36) were used to evaluate health-related quality of life, and the parenting stress index was used to assess the magnitude of stress within the parent-child system. Results The participants included seven adults (two females and five males) with genetically confirmed PWS and their respective main caregivers. The mean age of the adults with PWS was 25.28 years; range 18–31 years, SD 5.10; the mean BMI was 29.2 kg/m2, SD 6.43. All adults with PWS showed lower hand grip and lateral pinch strengths, fewer sit-to-stand cycles during the 30-s chair stand test, and greater average time during the timed up-and-go test when compared to the normative data on healthy adults. Balance was negatively correlated with the caregiver’s health concepts of social functioning (rs −0.879, P = 0.009) and with role limitations due to physical problems (rs −0.899, P = 0.006) and emotional problems (rs −0.794, P = 0.033); hand grip strength was negatively correlated with bodily pain (rs −0.800, P = 0.031), as assessed using the SF-36 questionnaire. The timed up-and-go test was positively correlated with the social relationship domain (rs 0.831, P = 0.021), as assessed using the WHOQOL-BREF questionnaire. The parenting stress index showed no association with the PWS patient’s physical activities. Conclusions All adults with PWS showed decreased upper and lower limb strength and functional mobility when compared to healthy adults. Some of their motor performance might have negative effects on their primary family members in terms of social participation and physical and emotional role limitations. Future research should explore the relationship between physical performances, psychological difficulties of PWS and caregiver’s QOL.

Abstract
Background Angelman syndrome (AS) is a rare disorder with a relatively well-defined phenotype. Despite this, very little is known regarding the unmet clinical needs and burden of this condition, especially with regard to some of the most prevalent clinical features—movement disorders, communication impairments, behavior, and sleep. Main text A targeted literature review using electronic medical databases (e.g., PubMed) was conducted to identify recent studies focused on specific areas of the AS phenotype (motor, communication, behavior, sleep) as well as epidemiology, diagnostic processes, treatment, and burden. 142 articles were reviewed and summarized. Findings suggest significant impairment across the life span in all areas of function. While some issues may resolve as individuals get older (e.g., hyperactivity), others become worse (e.g., movement disorders, aggression, anxiety). There are no treatments focused on the underlying etiology, and the symptom-based therapies currently prescribed do not have much, if any, empirical support. Conclusions The lack of standardized treatment protocols or approved therapies, combined with the severity of the condition, results in high unmet clinical needs in the areas of motor functioning, communication, behavior, and sleep for individuals with AS and their families.
