The psychophysiological impact of childhood autism spectrum disorder on siblings

Perceived Social Support, Normalization, and Subjective Well-Being Among Family Members of a Child with Autism Spectrum Disorder

The experience of family members of children with autism spectrum disorder (ASD) is not uniform. This study focused on mothers of a child with ASD (Study 1) and typically developing siblings (TDSs) during their emerging adulthood (Study 2). Similarities and differences were explored regarding a proposed model examining the paths of perceived social support (PSS) and normalization (a coping strategy) with subjective well-being: satisfaction with life (SWL) and positive affect (PA). Similarities were found in the paths between PSS, normalization, and SWL, in mothers and TDSs, but differences emerged regarding PA. These findings highlight the importance of PSS as a resource that contributes to normalization and SWL. Professional awareness of family members' PSS and their engagement in normalization is needed.

The role of family and individual factors in going through adolescence having a disabled sibling - analysis of a healthy child's functioning. A case-control study protocol

BACKGROUND

Having a disabled sibling can be a source of extremely important and enriching experiences that foster the development of social and emotional competences, as well as broadening the child's perspective and knowledge. On the other hand, it also poses many challenges for the siblings, especially in adolescence. Thus, the aim of the proposed project is to investigate the specificity of the growing up process in young people with disabled siblings.

PARTICIPANTS AND PROCEDURE

A total of 160 dyads (320 participants) - an adolescent and one of his/her parents - will take part in this cross-sectional case-control study. Participants will be assigned to four groups, having a sibling with: 1) intellectual disability, 2) motor disability, 3) chronic somatic disease, and 4) the control group - having a sibling without any disability. Both the healthy adolescent and one of the parents will fill out a set of questionnaires regarding the study variables: Questionnaire of Relationships with Siblings, Parental Attitude Scale-2, KidScreen-27, Parentification Questionnaire for Youth, Teenage Rebellion Questionnaire, Child Behavior Checklist 6-18.

RESULTS

The primary outcomes include investigating the healthy adolescent functioning in three environments: family, peers and school. The proposed research model focuses both on the difficulties associated with having a disabled sibling (e.g. possible occurrence of disorders) and resources (e.g. higher quality of relationships in the family, especially in the sibling subsystem).

CONCLUSIONS

The proposed comprehensive approach to the issue of disability in the family from the perspective of a healthy child will allow for a better understanding of the mechanisms underlying the process of growing up with disabled siblings.

The Relation of Parental Expressed Emotion, Parental Affiliate Stigma, and Typically-developing Sibling Internalizing Behavior in Families with a Child with ASD

Caregivers of children with autism spectrum disorder (ASD) experience greater stress, expressed emotion (EE), and affiliate stigma than caregivers of children without ASD. Siblings of children with ASD often experience greater negative functioning than siblings of individuals without ASD. The current study found significant interrelations among symptom severity and externalizing behavior in children with ASD; parental stress, affiliate stigma, and EE; and TD sibling internalizing behavior. In addition, certain subcomponents of affiliate stigma predicted unique variance in EE and TD sibling internalizing behavior. Findings may increase understanding of psychosocial functioning in families with children with ASD and allow clinicians to improve outcomes for all family members. Limitations of the study included self-report data, limited sample diversity, and a cross-sectional design.

Resiliency Intervention for Siblings of Children With Autism Spectrum Disorder: A Randomized Pilot Trial

BACKGROUND /OBJECTIVES

Neurotypical siblings (NT siblings) of children with autism spectrum disorder (ASD) are at elevated risk for emotional distress and adjustment problems. Resiliency is the ability to cope and adapt with ongoing stressors. We conducted a randomized waitlist-controlled pilot trial to examine the feasibility, acceptability, and preliminary efficacy of an adapted virtual mind-body resiliency group intervention for teen NT siblings of children with ASD.

METHODS

We modified the Stress Management and Resiliency Training-Relaxation Response Resiliency Program for NT siblings of children with ASD (SibChat). We randomly assigned teens (aged 14-17) to immediate intervention (IG) versus waitlist control (WLC). The intervention included eight 60-minute weekly video conference group sessions. We assessed feasibility (enrollment, attendance, and retention) and acceptability (post treatment survey and weekly relaxation response practice). We explored group differences in pre-post change scores for 1) stress coping (Measure of Current Status-A) and 2) resiliency (Current Experiences Scale) using independent samples t tests and effect size calculations.

RESULTS

We enrolled 83% of screened eligible teens. A total of 90% IG and 75% WLC participants attended at least 6/8 sessions. Among IG participants who completed the post treatment survey, 79% reported practicing relaxation response exercises at least "a few times a week". Comparing change in baseline to time 1, the IG showed better relative changes than the WLC group in stress coping (d = 0.60) and resiliency (d = 0.24).

CONCLUSIONS

Our pilot trial showed promising feasibility, acceptability, and preliminary efficacy of SibChat on at least one of the 2 primary outcomes supporting further testing of the SibChat intervention.

Psychopathological symptoms in parents and siblings of people on the autism spectrum: A systematic review and meta-analysis

Parents and siblings of children on the autism spectrum experience significant distress, and for this reason, it is essential to understand the most prevalent psychopathological symptoms among this population. This work aims to establish the prevalence of psychopathological symptoms in parents and siblings of individuals on the autism spectrum, following the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols (PRISMA-P) criteria. Searches were carried out using the PubMed/Medline, Embase, PsycINFO, SciELO, and Biblioteca Virtual em Saúde (BVS) databases. Twenty-three articles were included in this review. Depressive symptoms were the most frequently reported conditions, with a higher prevalence in mothers of children on the autism spectrum. In the meta-analysis, mothers of children on the autism spectrum scored higher by 0.42 standard deviations on the symptom scales (SMD 0.42; CI 0.25-0.59), with low statistical heterogeneity (I² 0%, p = 0.5) when compared with mothers of children with atypical development. The psychopathological symptoms of relatives should be investigated as part of the follow-up procedures for the child on the autism spectrum to facilitate their treatment.

Risk and resilience factors impacting the mental health and wellbeing of siblings of individuals with neurodevelopmental conditions: A mixed methods systematic review

OBJECTIVE

This pre-registered systematic review synthesised and evaluated the existing literature on self-reported mental health and wellbeing of siblings of individuals with neurodevelopmental conditions (NDCs).

METHODS

From 2437 identified studies published 2000-2022, 81 studies were included: 14 population- or cohort-based, 39 quantitative, 7 mixed method, and 21 qualitative outcome studies.

RESULTS

Seven sibling mental health (any psychiatric disorder, anxiety, depression, bipolar disorder, schizophrenia, internalising and externalising difficulties) and five wellbeing indicators were identified (quality of life, emotional adjustment, social wellbeing, somatic/physical wellbeing, and resilience/growth). Overall, siblings had increased risk of any psychiatric disorder, but they also reported experiences of growth and resilience, primarily in qualitative studies. 41 risk factors and 24 resilience factors associated with these outcomes were identified; the most frequently cited risk factor was symptom severity of the NDC sibling, while the most common resilience factor was adaptive/active coping at the individual sibling level. Studies showed high methodological heterogeneity and 90 different self-report measures were used.

CONCLUSIONS

Sibling mental health indictors are heterogeneous and cumulative risk factors may result in poorer wellbeing. There is a need for consistent reporting of family and sibling characteristics, a strengths-based approach to assessment, and identification of protective and resilience-promoting factors.

The Clinical Implications of the Academic Performance of the Siblings of Individuals With Autism Spectrum Disorder

We all know that autism spectrum disorder (ASD) can affect academic performance. Many children with autism face different challenges at school. However, less attention is paid to the siblings of autistic children, who are at a high risk of ASD or the broad autism phenotype (BAP). Recent data also shows that many siblings of ASD children suffer from neurodevelopmental disorders, mental health problems as well as poor academic performance. This review will look at the possible etiologies of the poor school performance of autistic children's siblings, with an emphasis on the challenges they face. We will also highlight the clinical implications of these findings, and the possible solutions that can help this vulnerable group.

Predictors of Suicide Attempts of Individuals with Autism and Their Siblings

The occurrence of mood- and anxiety-related conditions among family members of individuals diagnosed with autism spectrum disorder (ASD) increases the risk of suicide attempts and has also created assessment and treatment issues for clinicians and parents. Recorded rates of mental health disorders comorbid with suicide attempts among individuals on the spectrum range from 29% to 52%. The purpose of this study was to investigate the presence of predictors of suicide attempts among sibling dyads (pairs of siblings in which one sibling is on the autism spectrum). Growing evidence in the literature indicates a link between a diagnosis of autism and mental health. A web-based survey was used to collect data from individuals on the spectrum and their siblings. A sample of 144 individuals was finalized for the analyses. Logistic regression analysis was conducted to assess the predictors of suicide attempts in the sample. Depression, anxiety, sexual orientation, and marital status were all used as predictors in the logistic regression analyses. Both levels of anxiety and sexual orientation were found to be significant predictors for suicide attempts. Recommendations for future research, assessment, and treatment are presented.

Developmental and mental health risks among siblings of patients with autism spectrum disorder: a nationwide study

Studies have suggested that unaffected siblings of patients with autism spectrum disorder (ASD) have some other neurodevelopmental abnormalities. However, the risks of mental and developmental disorders have rarely been investigated among unaffected siblings. Using Taiwan's National Health Insurance Research Database, 1304 unaffected siblings born between 1980 and 2010 with ASD probands and 13,040 age-/sex-/family structure-matched controls were included in our study and followed up from 1996 or birth to the end of 2011. Developmental delay, language delay, developmental coordination disorder, attention-deficit hyperactivity disorder (ADHD), anxiety disorders, disruptive behavior disorders, unipolar disorder, and bipolar disorder were identified during the follow-up period. Unaffected siblings were more likely to develop any developmental delay, developmental speech or language disorder, developmental coordination disorder, intelligence disability, ADHD, anxiety disorders, unipolar depression, and disruptive behavior disorders compared with the control group. Brothers of patients with ASD had a higher risk of neurodevelopmental abnormalities, ADHD, anxiety disorders, and disruptive behavior disorders; sisters were prone to having neurodevelopmental abnormalities, ADHD, anxiety disorders, unipolar depression, and disruptive behavior disorders. Unaffected siblings of patients with ASD were prone to developing any developmental or mental disorder later in life. Clinicians and public health officials should pay more attention to the developmental condition and mental health of unaffected siblings of patients with ASD.

A systematic review of social support for siblings of children with neurodevelopmental disorders

BACKGROUND

Social support is a protective factor for siblings of children with neurodevelopmental disorders.

AIMS

We reviewed studies on social support received by siblings of children with neurodevelopmental disorders.

METHODS AND PROCEDURES

We conducted a pre-registered systematic review (CRD42020207686), searching PsycINFO, MEDLINE, Web of Science, and Scopus.

OUTCOMES AND RESULTS

Fifteen articles were eligible for the review, 13 of which used cross-sectional designs. Two studies investigated sibling social support after an intervention. Multiple variables were negatively related to social support (e.g., sibling depression, loneliness, stress). Variables that were positively related to social support included prosocial behavior, competence (academic, social, and activity-related), problem-focused coping, and family quality of life. Potential moderators of the relationship between social support and psychosocial adjustment included the type of disorder of the affected sibling and the type of social support provider. We conclude with an overview of the reliability and validity of the seven social support measurements used across the studies.

CONCLUSIONS AND IMPLICATIONS

Lower levels of social support are associated with more negative psychosocial adjustment among siblings of children with neurodevelopmental disorders. We encourage future researchers to further investigate ways to increase social support for siblings to improve outcomes.

Acceptability of A Virtual Mind-Body Group Intervention for Teen Siblings of Children with Autism Spectrum Disorder

Teenage siblings of children with autism spectrum disorder (ASD) are at risk of worse mental health outcomes than their peers, yet there have been few interventions focused on improving their psychosocial wellbeing. This study explored the acceptability of an 8-session virtual group mind-body resiliency intervention for teen siblings of children with ASD. We used mixed methods to assess quantitative and qualitative survey results. Participants reported that the intervention had the right amount of sessions (88%), structure (74%), and duration (89%). Most participants felt comfortable during sessions (74%), found it helpful to learn mind-body exercises (74%), and that the intervention helped in coping with stress (71%). Though participants were satisfied with the opportunity to meet peers, they desired more social connection.

Feelings of Loneliness and Social Dissatisfaction in Siblings of Children with Autism Spectrum Disorders: The Role of Birth Order and Perceived Social Support

Loneliness has been associated with several adverse psychosocial outcomes in childhood and adolescence. The present study aimed to investigate feelings of loneliness and social dissatisfaction in school-aged typically-developing (TD) siblings of children with an autism spectrum disorder (ASD). For this purpose, 118 siblings of children with ASD and 115 siblings of TD children and one of their parents participated in this study. Siblings of ASD-children reported higher levels of loneliness and social dissatisfaction than the controls. The hierarchical multiple regressions performed revealed that those feelings were inversely associated with being the first-born and with specific aspects of social support as perceived by the parent. The younger siblings of ASD-children seem to be in need of certain interventions beyond social support.

Examination of the Effectiveness and Acceptability of a Play-Based Sibling Intervention for Children with Autism: A Single-Case Research Design

Complementary and reciprocal interactions are a defining feature of sibling relationships for young children. However, the social and communication difficulties of children with autism spectrum disorder (ASD) can make reciprocal play more difficult and play between siblings can be less rewarding. Sibling play can serve an important role in intervention and family cohesiveness, but there is no consistent method for involving siblings in intervention benefitting the sibling dyad. This study evaluated a novel treatment package including training siblings on play strategies to increase positive sibling play in combination with a sibling support group to offer social support for the neurotypical sibling (NT). The effects of the treatment package on NT sibling play and fidelity of implementation of naturalistic play strategies was examined using a concurrent multiple-baseline design across six dyads, five of whom completed the intervention. After behavior skills training, all NT siblings increased the number of strategies they used, and increased the frequency of initiations towards their sibling with ASD. In addition, the percentage of reciprocal play between siblings increased. Generalization probes and follow-up probes demonstrated above-baseline levels of performance across most dyads, indicating that the skills learned generalized across other toys and were maintained over time. Only three of the sibling support group sessions were completed due to the COVID-19 pandemic. Although the effectiveness of the sibling support group cannot be determined, social validity questionnaires suggest siblings and parents valued and liked the support group.

A systematic review of the experience of being a sibling of a child with an autism spectrum disorder

Difficulties associated with Autism Spectrum Disorders can cause considerable impact on personal, familial, social, educational and occupational functioning. Living with a child who has an Autism Spectrum Disorder can therefore pose a challenge to family members, including typically developing siblings. However, it is only in recent years that the experience of typically developing siblings has become a focal point. A systematic review using keywords across six databases was undertaken to summarise qualitative studies that focused on the experience of being a sibling of a child with an Autism Spectrum Disorder. Fifteen studies met inclusion criteria and a thematic synthesis was completed. The synthesis found that having a sibling who has an Autism Spectrum Disorder can impact typically developing sibling's self-identity and personal development in a number of ways. Similarly, interactions with the sibling who has Autism Spectrum Disorders and with other individuals can evoke a myriad of experiences that can both benefit and challenge typically developing siblings. The ability of typically developing siblings to cope with adverse experiences needs to remain a focus. This synthesis concludes that further research is needed to identify which methods are the most effective in supporting typically developing siblings of children with Autism Spectrum Disorders.

Children and young people's experiences of having a sibling with complex health needs: a literature review

Children with complex health needs require significant healthcare input for one or more conditions. Much of the literature on the effects of living with children with complex heath needs focuses on parents, and there is little research into the effects on siblings. This article reports on a literature review that examined the experiences of siblings growing up with a brother or sister with complex health needs and how this affects their lives. Three main themes were identified: emotional experiences; coping strategies and support; and family life. The findings identified in relation to mixed emotions, coping strategies and support systems are similar to those of studies of siblings of autistic children and children with cancer. However, in most countries the provision and availability of support for this group of siblings is inadequate.

Challenges and Growth: Lived Experience of Adolescents and Young Adults (AYA) with a Sibling with ASD

Adolescent and young adult (AYA) siblings of individuals with autism experience unique challenges that can promote both growth and emotional maladjustment. This study explored sibling and parent reports of siblings' lived experiences and identified learning, stressors, and concerns from those experiences. 20 neurotypical (NT) AYA siblings (ages 13-24), and 21 parents were interviewed. Themes that emerged from the data analysis included: (1) learning, empathy, and compassion (2) relationship between the degree of functional impairment and the nature of the sibling relationship; (3) reluctance to share information about siblings with peers; (4) hypervigilance associated with unpredictable behavior; (5) worries and concerns about the future. These findings contribute to the existing literature on the impact and nature of neurotypical siblings' lived experience.

Effects of Nature-Based Group Art Therapy Programs on Stress, Self-Esteem and Changes in Electroencephalogram (EEG) in Non-Disabled Siblings of Children with Disabilities

The purpose of the present study was to examine changes in brain waves, stress, and self-esteem after a continuous eight-week nature-based art therapy program in the forest in non-disabled siblings of children with disabilities. A total of 29 participants participated in this study (art therapy program group, n = 18; control group, n = 11). The art therapy program group received eight weekly sessions of art therapy lasting 60 min each. Pre- and post-test results showed positive changes in the brain function index and stress levels of the participants in the art therapy program group. On the self-esteem scale, overall and social self-esteem increased significantly. In conclusion, creative activities in the forest can increase resistance to diseases through mechanisms that relieve stress and increase self-esteem. If art therapy that emphasizes somatosensory experience, creative expression, and self-motivation is accompanied by forest activities, this combined intervention can elicit positive physical and psychological changes.

General Cognitive Abilities and Psychosocial Development in Children and Adolescents Having a Co-Twin with Down Syndrome

OBJECTIVE

To examine the general cognitive and psychosocial development in children and adolescents having a co-twin with Down syndrome.

STUDY DESIGN

A case control study with an individually matched control group was conducted. Participants included families with twins discordant for Down syndrome as well as with typically developing twins. The group of unaffected co-twins aged 4-16 years was compared with a control group of typically developing twins in terms of general cognitive abilities, behavioral problems, and prosocial behavior. The age and sex and the sex composition of the twins were individually matched. The Sijnders-Oomen nonverbal intelligence test was applied to assess children's IQ, and parents completed the Strength and Difficulties Questionnaire.

RESULTS

The unaffected co-twins did not differ from typically developing twins with respect to their IQ. Concerning the psychosocial development, significantly heightened values in unaffected co-twins twins were only obtained for the conduct problems scale (P = .01; r = 0.45), neither for the total difficulties score nor for the other behavioral problem scales significant differences were found.

CONCLUSIONS

The general cognitive development of the unaffected co-twin of children with Down syndrome is not affected by the presence of their Down syndrome twin. Unaffected co-twins showed increased conduct problems, which is most pronounced in the younger children.

A parent-sibling dyadic interview to explore how an individual with Autism Spectrum Disorder can impact family dynamics

BACKGROUND

Autism Spectrum Disorder (ASD) is a life-long condition which affects the individual and their family system. Little research understands the impact of an ASD upon families, how this may change over time and how COVID-19 has impacted these dynamics.

AIMS

To explore the impact of an ASD on the lived experiences of parents and neurotypical adult siblings, including during the UK COVID-19 lockdown.

METHODS

Eight parent-sibling dyads (16 individuals) completed semi-structured interviews discussing their family before, during and after receiving the ASD diagnosis, and in relation to the first UK lockdown. Interview transcripts were analysed using Interpretative Phenomenological Analysis.

RESULTS

Three super-ordinate themes were identified: Dominated by ASD; Family Cohesion; and the Need for Support.

CONCLUSIONS

The data suggested a closeness within the families and an adoration towards the individual with ASD (IWA). Dyads were, to an extent, consumed by the diagnosis both presently and in the future, implicating the need for a stretch in services to support parents and neurotypical siblings. In terms of the first UK lockdown, the IWA added an extra layer of difficulty to the dyads work-life balance yet there was an essence of family cohesion. Future research should consider longitudinal methods and explore the impact of ASD co-morbidities upon family dynamics.

Exploring the experiences of siblings of adults with intellectual/developmental disabilities during the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic has caused many adults with intellectual/developmental disabilities (IDD) to lose their daily routines and social support, and as a result, many adults with IDD are increasingly reliant on their family caregivers. Siblings often play a crucial support role for their brothers and sisters with IDD. As such, this study aimed to describe the experiences of adult siblings of people with IDD during the COVID-19 pandemic.

METHODS

The Sibling Collaborative worked with researchers to codesign an online survey, completed by 91 people, exploring sibling supports and concerns during the COVID-19 pandemic. The survey also aimed to identify helpful resources for siblings during this time.

RESULTS

The results showed that the majority of siblings are supporting their brother or sister with IDD during the COVID-19 pandemic and are concerned about the health and well-being of their brother/sister. The most common concern related to disruption of their brother's or sister's routine and activities. Although responses of older and younger siblings did not differ from each other, siblings whose brother or sister with IDD lived with family had some unique concerns relative to those whose siblings no longer lived with family. Siblings described how their own self-care and relationships with others, as well as support for their brother/sister, were particularly helpful during the COVID-19 pandemic.

CONCLUSIONS

Siblings are providing key support to their brother or sister with IDD during the COVID-19 pandemic, and they too must be supported. Siblings should be included in efforts to disseminate resources targeting people with IDD and their feedback and input must be obtained. It is also important to include sibling mental wellness as caregiver supports are created and implemented. More research is needed to further understand how to support sibling caregivers.

Seeing the siblings: Gender differences in emerging-adult siblings of individuals with autism spectrum disorder

BACKGROUND

The present study focused on typically developing siblings (TDS) in emerging adulthood of individuals with autism spectrum disorder (ASD) and sought insight into how gender may interact with positive and negative affects in this population. In addition, we aimed to explore the gender differences as a moderator in the link between personal resources (i.e., family cohesion and flexibility coping strategy) and positive and negative affects among such TDS. An understanding of gender differences in this population should prove relevant to the development of potential interventions.

METHOD

A total of 116 emerging adult (age 18-29) TDS of younger siblings with ASD (the latter were under the age of 18 at the time of data collection), 80 females and 36 males, participated in the study. All participants completed self-report measures.

RESULTS

Female TDS reported higher negative affect than male TDS, while no differences emerged regarding positive affect. Female siblings reported higher family cohesion and higher flexibility in the forward-focused subscale of flexibility coping strategy, but not in its trauma-focused subscale, compared to male siblings. Additionally, gender moderates the links between family cohesion and positive affect but not negative affect. Gender also moderates the association between flexibility and negative affect, but not positive affect.

CONCLUSIONS

This study highlights the gender differences among TDS in emerging adulthood of individuals with ASD in relation to negative affect, family cohesion, and flexibility coping strategy. Understanding the gender-specific internal and external experiences of TDS as interplaying with their resources, at the unique developmental stage of emerging adulthood, may afford to identify TDS in need and to suggest potential interventions.

Self-reported Health-Related Quality of Life (HRQOL) and Anxiety Among Greek School-Age Siblings of Individuals with Autism Spectrum Disorders (ASD) in Relation to Parental Mental Health and Social Support

Health-Related Quality of Life (HRQOL) and anxiety were measured in 233 school-age siblings of individuals with Autism Spectrum Disorders (ASD) and siblings of Typically Developing (TD) children in Greece. The aim of the study was to investigate for any association between siblings' HRQOL or anxiety and parental mental health, perceived social support as well as major demographic factors. It was found that the disability group (ASD-sibs) showed elevated anxiety levels and poorer HRQOL than controls. In hierarchical multiple regression models, the anxiety of ASD-sibs was significantly associated with parental anxiety independent of parental perceived social support and demographic factors, whereas the HRQOL of ASD-sibs was associated with perceived social support independent of parental physical and mental health and demographic factors.

Functioning Among Typically Developing Siblings of Individuals with Autism Spectrum Disorder: A Meta-Analysis

The literature on typically developing siblings of individuals with autism spectrum disorder (ASD-Sibs) provides inconsistent results, with some studies reporting ASD-Sibs are more likely to have negative outcomes than comparison groups, and others reporting no significant differences. Therefore, the purpose of this study was to meta-analytically aggregate study effect sizes to more accurately calculate the degree to which ASD-Sibs function similarly or differently compared to siblings of people who do not have ASD. Studies were eligible for inclusion if they had a sample of ASD-Sibs older than 5; reported on emotional, psychological, behavioral, or social functioning; and provided information necessary for calculating relevant effect sizes. Results from 69 independent samples indicated that ASD-Sibs have significantly more negative outcomes than comparison groups overall (g = - 0.26); specific areas of functioning in which ASD-Sibs fared worse include internalizing behavior problems, psychological functioning, beliefs, social functioning, and the sibling relationship, but no significant differences in adjustment, attention/hyperactivity, externalizing behavior problems, coping, or family functioning. Noteworthy sub-areas of functioning in which ASD-Sibs also fared worse included beliefs about disability (g = - 0.56), anxiety symptoms (g = - 0.25), and depression symptoms (g = - 0.36). In terms of comparison group, ASD-Sibs had significantly lower functioning than siblings of individuals with other intellectual and developmental disabilities (g = - 0.31), including Down syndrome (g = - 0.40) and siblings of individuals without any disabilities (g = - 0.31). Clinicians and service providers should work to ensure that ASD-Sibs are included in family interventions and support strategies, and researchers should further explore individual differences that may relate to enhanced or impaired functioning in ASD-Sibs.

Randomized controlled trial of a sibling support group: Mental health outcomes for siblings of children with autism

LAY ABSTRACT

Typically developing siblings of a child with autism spectrum disorder may show mental health difficulties. A support group is one approach to help typically developing siblings. During support groups, typically developing siblings discuss their feelings, learn coping strategies and problem-solving skills, and develop a peer network. We compared a support group to participation in a similar group without a focus on the sibling with autism spectrum disorder. Some areas of mental health improved. Improvements were also impacted by autism spectrum disorder symptom severity in the sibling with autism spectrum disorder. Findings suggest continuing to examine how support groups can help typically developing siblings and for which siblings support groups might be particularly effective.

Using administrative data to examine variables affecting the mental health of siblings of children who have a developmental disability

BACKGROUND

There is evidence that siblings of children with a developmental disability (DD) experience poorer mental health outcomes and increased stress compared to siblings of non-disabled children. The variables which contribute to this are unclear.

AIMS

This study was designed to examine population-level and individual variables associated with differences in mental health outcomes among siblings of children who have a variety of developmental disabilities.

METHODS

Population-level administrative health data covering 1985-2014 for the province of British Columbia, Canada were used to develop a cohort of over 45,000 children who have a sibling with a DD. Individual-level, demographic and health care services variables were used in logistic regression to assess their relationship to diagnoses of depression or other mental health problems.

OUTCOMES

Odds of a diagnosis of depression or a mental health problem other than depression were associated with sex of the non-disabled sibling, sex of the child with the developmental disability, type of disability, birth order and income.

CONCLUSIONS

Type of developmental disability, and characteristics of the non-disabled sibling and their family are associated with mental health outcomes of siblings of children with a DD.

A population-level study of the mental health of siblings of children who have a developmental disability

This study used population level administrative data for health service utilization from the Ministry of Health, British Columbia, Canada to assess the mental health of siblings of children who have a developmental disability. At a population level, the study found strong evidence that siblings of children who have a developmental disability experience higher odds of a depression or other mental health diagnosis compared to siblings of children who do not have a developmental disability. In addition, there was evidence that in families with a child with a developmental disability, siblings who are diagnosed with depression or another mental health problem use physician and/or hospital services for these conditions to a greater extent than siblings who are diagnosed with depression or a mental health problem but do not have a family member with a developmental disability. Evidence of increased depression and mental health problems existed across all income levels, indicating that other stressors may have an impact. These findings suggest that siblings of children who have a developmental disability are a vulnerable group in need of programs and services that support their mental health.

•

This study used population-level administrative health data to examine some of the variables affecting mental health in 45,578 siblings of children who have a developmental disability (DD) compared to two comparison groups of siblings of children who do not have a developmental disability.

•

Siblings of children who have a DD experience increased odds of a depression or other mental health diagnosis compared to either of the two comparison groups.

•

In addition there was evidence that siblings of children who have a DD and who have a diagnosis of depression or another mental health problem use the health care system to a greater extent than siblings of children who do not have a DD but have a diagnosis of depression or another mental health problem.

•

Evidence of increased depression or another mental health problem existed across all income levels.

•

This is the first study to use population-level administrative health data to compare e mental health outcomes of siblings of children with a DD to siblings of children without a DD.

Neuroticism and extraversion mediate the relationship between having a sibling with developmental disabilities and anxiety and depression symptoms

Background Children growing up with a sibling with disabilities report higher levels of depression and anxiety symptoms as adults. Here, we examined whether personality characteristics also play a part in mediating this relationship. Method We tested for differences in personality traits between 132 individuals who have a sibling with developmental disabilities and 132 closely matched comparisons. Results Differences in Big Five factors of personality were demonstrated across the disability groups and between the disability groups and the comparisons, especially in Extraversion, Neuroticism and Openness. Individuals growing up alongside a sibling with developmental disabilities have a higher tendency to experience anxiety and depression symptoms, and this research is the first demonstration that personality traits mediate this relationship. Specifically, Neuroticism is a strong mediator of anxiety while both Neuroticism and Extraversion contribute mediating effects toward the development of depression. Limitations Our study made use of self-report methodology which, although having recognized limitations, is more reliable than parental reports. Given the cross-sectional nature of our design, we were not able to examine pre-existing developmental factors that may have influenced the participant's propensity to particular personality traits and affective disorders. However, we obtained a large sample and closely matched participants to examine differences between those with a sibling with disabilities and those without. Conclusions As such, differences in personality traits have important implications for the understanding and treatment of siblings presenting with anxiety and depression symptoms. We recommend that intervention should target those high in Neuroticism among individuals who have a sibling with disabilities, and that more social support is put in place for siblings to mitigate their tendency towards introversion and buffer them against psychological maladjustment.

Siblings' experiences of growing up with children with autism in Taiwan and the United Kingdom

BACKGROUND

A child's diagnosis of autism impacts their whole family, in both positive and negative ways, that may be influenced by cultural beliefs.

AIMS

We aimed to describe the experiences of mothers and typically-developing siblings of children with autism in two cultural contexts.

METHODS

Fourteen mother-sibling dyads from Taiwan and the UK participated in semi-structured interviews.

RESULTS

Whilst there were similarities in sibling experiences, a negative tone regarding the influence of autism was more evident in Taiwan, where families also cited societal judgement and cultural-specific expectations. In the UK, a more balanced tone was apparent: mothers emphasised educating and involving the siblings. It is speculated that UK siblings had a greater understanding of their parents' stress, leading to more adaptive family dynamics. Various types of support service were mentioned in the UK, whereas the availability of social services and support appeared to be relatively limited in Taiwan.

IMPLICATIONS

Our data suggest that cultural context may have a significant impact on the responses of the family members. This is mediated by both differences in attitudes and traditions, and availability of resources. Support for family members needs to be sensitive to such cultural differences, as well as recognising positive experiences.

School Functions in Unaffected Siblings of Youths with Autism Spectrum Disorders

This study investigated school functioning among unaffected siblings of youths with autistic spectrum disorder (ASD) and identified the correlates for school maladjustment. We recruited 66 youths with a clinical diagnosis of ASD, aged 8-19, their unaffected siblings and 132 typically developing controls (TD). We found that ASD youths had poorer school functions than unaffected siblings and TD. Unaffected siblings had poorer attitude toward schoolwork and more severe behavioral problems at school than TD. Several associated factors for different scholastic functional domains (i.e., academic performance, attitude toward school work, social interactions, behavioral problems) in the siblings included IQ, autistic traits, inattention/oppositional symptoms, sibling relationships, etc. Our findings suggest the need of assessing school functions in unaffected siblings of ASD.

The Role of the Broader Autism Phenotype and Environmental Stressors in the Adjustment of Siblings of Children with Autism Spectrum Disorders in Taiwan and the United Kingdom

The influence of the broader autism phenotype (BAP) on the adjustment of siblings of children with autism has previously been researched mainly in Western cultures. The present research evaluated a diathesis-stress model of sibling adjustment using a questionnaire study including 80 and 75 mother-typically developing sibling dyads in Taiwan and the United Kingdom (UK). UK siblings reported elevated adjustment difficulties compared to the Taiwanese sample and to normative data. Whilst higher BAP levels were generally associated with greater adjustment difficulties, differences were found across cultures and respondents. Although significant diathesis-stress interactions were found, these were in the opposite direction from those predicted by the model, and differed across cultural settings. Implications for culturally-sensitive sibling support are considered.

Psychiatric care of children with autism spectrum disorder - What do their siblings think about it? A qualitative study

The expectations and role of families in the care of children with autism spectrum disorder are increasingly important. Nonetheless, no study has thus far explored the perspectives of siblings about the care received by a brother or sister with this disorder. The objective of this study was to fill this gap in the literature. This multicentre qualitative study took place in France, where we conducted semi-structured interviews with adolescents who were older siblings of children receiving care in a day hospital for an autism spectrum disorder. Data collection by purposive sampling continued until we reached 'theoretical sufficiency', and data analysis was thematic. The study included 20 participants: 13 sisters and 7 brothers. Four themes emerged in the data analysis: (1) the treatment targets, (2) the treatment's perceived effectiveness, (3) the complex questions it raises and (4) the role of intrafamily relationships. Our results allowed us to report original aspects of the experience of siblings, in particular, their confusion with regard to the treatment, their difficulty in separating themselves from their parents' discourse and their assertion of their role as caregivers for their younger brothers and sisters.

Self-reported stress among adolescent siblings of individuals with autism spectrum disorder and Down syndrome

Despite the prevalence of studies showing increased stress among mothers of individuals with autism spectrum disorders, few studies have examined general stress among typically developing siblings. This study used an online survey to compare the levels of self-reported stress between adolescent siblings of individuals with autism spectrum disorder and Down syndrome. Sibling of individuals with autism reported significantly more overall stress than did siblings of individuals with Down syndrome, as well as more stress specifically attributed to the brother/sister with autism. The two groups did not differ on perceived social support from family and friends. In linear regression models, the disability group (autism vs Down syndrome) was significantly related to sibling stress above and beyond target child behavior problems, perceived social support, and demographic factors. These results help shed light on the daily experiences of adolescent siblings of individuals with autism and call for more research into potential interventions to address increased stress levels.
