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

Cognition, mental health and quality of life amongst siblings of preterm born children: A systematic review

AIM

Globally, 1 in 10 babies are born preterm. Families with preterm born infants may suffer strains related to the presence of a preterm child. To date, most evidence focuses on the outcome of children born preterm and of their parents. Our objective was to investigate the evidence on the impact of having a preterm born sibling on cognitive function, mental health and quality of life of term-born siblings and critically appraise the evidence.

METHODS

We searched five electronic databases, Google Scholar and reference lists. Two reviewers independently conducted screening, data extraction and critical appraisal.

RESULTS

We retrieved 9121 articles. After duplicates, titles, abstract and full text review, seven studies met the inclusion criteria. One study reported higher anxiety and depression scores on index cases in the term born comparison group, compared to the index cases in the preterm born sibling group. Another study reported more feelings of reduced parental attention, and more interpersonal problems in the preterm born sibling group, than the comparison group.

CONCLUSIONS

Although two studies reported a difference in outcomes between index cases in preterm born sibling groups and comparison groups, the scarce evidence did not allow us to delineate an effect or lack of it.

When a Sibling Has Autism: Narrative Review of Interventions for Typically Developing Siblings

Being a typically developing sibling to a child with autism spectrum disorder (ASD-Sib) can be associated with several behavioral and mental health problems. With this understanding, researchers are beginning to focus on sibling-oriented interventions. This review seeks to evaluate the current literature on such interventions. We searched digital databases and identified eight relevant studies. The sample (n = 247) had an age range of 4-16 years. The outcomes were generally positive, with improvements in different facets of ASD-Sibs. Results differed due to varied intervention styles, outcome variables, methods, and samples. Our findings highlight the potential for improvement in ASD-Sib's knowledge of autism and their psychological functioning and hence call for further research with robust methods.

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.

The importance of informal support and a listening ear: A narrative analysis of emotional conflict and support needs of siblings of children with a psychiatric disorder

This study investigates the self-reported impact of children's psychiatric disorders on their siblings and assesses what forms of support such children most value. We used a qualitative research design with open interviews to stimulate children between 8 and 15 years old to talk about their experiences living with a brother or sister with a psychiatric disorder. Their stories were analysed within a hermeneutic phenomenological framework in order to identify narrative themes and interpret the meaning of shared experiences. From our analysis, nine shared narrative themes emerge. Overall, siblings report feeling conflicted about adapting their lives to their brother's or sister's disorder and signal a need for personalized attention from parents. They also indicate that being involved in the care for their brother or sister helps them to better understand their behaviour. Finally, siblings reveal that, in their experience, formal, protocolized forms of support foreground family problems and stress. Thus, we recommend to involve children in the care process; to acknowledge their personal needs and conflicts; and to be mindful of the style of support: help offered in an informal or playful way, instead of formal and protocolized, could be a more effective way of meeting siblings' needs.

How my life is unique: Sibling perspectives of autism

LAY ABSTRACT

The impact of autism on the family is an important area of study. Much of the existing literature has focused on the parent perspective, with less emphasis on the experiences of other family members, especially non-autistic siblings. This study aimed to explore the lived experiences of a sample of nine 8- to 17-year-old non-autistic siblings of children and youth on the autism spectrum. We interviewed non-autistic siblings and analysed the written transcripts. Our results revealed the following themes: (1) Role disparities, different expectations; (2) Connection and disconnection; and (3) Our family is (extra)ordinary. Our study findings highlight siblings' unique and collective perspectives regarding their brother or sister on the spectrum within the broader family unit. We discuss the implications of these results on siblings of autistic children and youth.

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.

Psychosocial Interventions and Support Groups for Siblings of Individuals with Neurodevelopmental Conditions: A Mixed Methods Systematic Review of Sibling Self-reported Mental Health and Wellbeing Outcomes

Siblings of persons with neurodevelopmental conditions (NDCs) have increased risk of poorer psychosocial functioning. This systematic review evaluated quantitative and qualitative evidence on sibling mental health and wellbeing outcomes following psychosocial interventions and the risk and protective factors associated with post-intervention outcomes. From 2025 identified studies published from 1991 to 2022 across ten databases, 24 studies were included. The largest immediate post-intervention improvements were in self-esteem, social wellbeing and knowledge of NDCs. The most sustained improvements in intervention groups at follow-up periods were in emotional and behavioural adjustment and NDC knowledge. There were positive, but small, differences in favour of the intervention groups on knowledge of NDCs, self-esteem, coping and the sibling relationship as compared to waitlist control groups. Psychosocial interventions for siblings are heterogeneous, and more data, including consideration of unique family circumstances, are needed to improve reporting and replicability, to measure effectiveness and tailor necessary supports.

Programs to Prepare Siblings for Future Roles to Support Their Brother or Sister with a Neurodevelopmental Disability: a Scoping Review

Purpose of Review

To identify and map the characteristics and outcomes of programs designed to prepare siblings for their future roles with their sibling with a neurodevelopmental disability.

Recent Findings

Existing programs to support siblings of individuals with a neurodevelopmental disability often focus on providing information about neurodevelopmental disabilities, creating a community for siblings to connect with each other, and connecting siblings to resources and services to support them in their roles. Some programs are offered to the whole family with specific sessions for siblings. While these program descriptions are provided in the literature, there is limited understanding about the impacts and outcomes of these programs on siblings of an individual with a neurodevelopmental disability.

Summary

Fifty-eight articles (published between 1975 and 2020, with > 50% published since 2010) met the inclusion criteria, representing 54 sibling programs from 11 countries. Extracted data represented 1033 (553 females) sibling participants, between 4 and 67 years old. Twenty-seven programs focused on the outcome of knowledge acquisition for the siblings and thirty-one programs focused on the outcome of empowerment for the siblings to teach skills to their sibling with a neurodevelopmental disability. While there is an increasing number of programs for siblings of individuals with a neurodevelopmental disability in the past decade, there is a lack of siblings as co-developers or facilitators. Future research should consider the various roles that siblings can have in programs to address their needs.

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.

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.

Temperament in Infancy Predicts Internalizing and Externalizing Problem Behavior at Age 5 in Children With an Increased Likelihood of Autism Spectrum Disorder

Differences in temperament have been linked to later mental health. Children with autism spectrum disorder (ASD) have an increased likelihood of experiencing such problems, including anxiety, depression, attention deficit/hyperactivity disorder, and oppositional defiant disorder; yet, relations between early temperament and later mental health are not well understood. In this paper, we assess the relationship between temperament in infancy and internalizing and externalizing behavior at age 5, in 178 children at an increased likelihood of being diagnosed with ASD (i.e., younger siblings of children with ASD). Temperament was assessed using the parent-reported Infant Behavior Questionnaire (IBQ) at 6 and 12 months of age and the Toddler Behavior Assessment Questionnaire-Revised (TBAQ-R) at 24 months of age. Mental health problems were assessed using the parent-reported Child Behavior Checklist (CBCL) at age 5. The data were analyzed using hierarchical multiple regressions, with individual temperament subscale scores as single predictor variables (Subscale Score) or temperament profiles using confirmatory factor analyses (Person-Centered Profile) in the first block, Autism Diagnostic Observation Schedule total severity scores at age 3 in the second block, and expressive and receptive language scores (from Mullen Scales of Early Learning) at age 3 in the third block for each model. Three main findings were: (1) 4 of 6 IBQ subscales at both 6 and 12 months significantly predicted internalizing and externalizing problems at age 5; (2) 9 and 8 of 13 TBAQ-R subscales at 24 months significantly predicted internalizing and externalizing problems, respectively, at age 5; and (3) a "sticky attention" temperament profile significantly predicted internalizing problems, whereas a "low-focused" profile significantly predicted externalizing problems, both at age 5. The results of this study support the supposition that temperament is a trans-diagnostic risk factor for later mental health conditions. Exploring temperament profiles and trajectories may illuminate early avenues for prevention in siblings of children with ASD who are at an increased likelihood of experiencing mental health problems, regardless of ASD diagnostic status.

Through the eyes of a child: Sibling perspectives on having a sibling diagnosed with autism

BACKGROUND

Sibling perspectives on the experiences of families caring for an autistic child are often overlooked in autism research. While qualitative research on these lived experiences has grown, it continues to primarily focus on parent reports.

AIMS

This study explored how having a sibling with autism impacts the non-autistic siblings within a family systems framework. The goal of the current study was to expand the literature by exploring the impacts of autism on the sibling subsystem as reported by the parents and the non-autistic siblings themselves.

METHODS AND PROCEDURES

The researchers interviewed 15 non-autistic siblings (aged 7-17) and 15 parents of children with autism to understand the experience of growing up with a sibling with autism. Content analysis was used to develop the interview protocol and analyze responses. Parent and non-autistic sibling reports of both siblings' effects on each other's development are triangulated with existing research.

RESULTS

Findings indicate novel emotional skill-building occurs in non-autistic siblings, as well as some unique risk factors for internalizing and externalizing problems if non-autistic siblings' needs become deprioritized. Family stress, external relationships, intrapersonal and social skill development, and other implications of this unique relationship are discussed.

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.

Quality of the sibling relationship when one sibling has autism spectrum disorder: A randomized controlled trial of a sibling support group

LAY ABSTRACT

The sibling relationship can be negatively impacted when one child has autism spectrum disorder. One way to improve the quality of that relationship is through typically developing sibling participation in a support group in which they learn about autism spectrum disorder and coping skills, develop a peer network, and discuss their feelings. Compared to participating in a similar group without a focus on autism spectrum disorder, siblings in the support group showed improvements in the quality of the sibling relationship. Findings suggest that sibling support groups can be a valuable resource to improve sibling relationship quality when one sibling has autism spectrum disorder.

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.

Empathy and Prosocial Behavior in Siblings of Children with Autism Spectrum Disorder: a Systematic Review

Siblings of children with ASD have, as a group, more autistic traits than typically developing individuals. A high prevalence of autistic traits may (or may not) include lower scores on measures of empathy and prosocial behavior compared with typically developing individuals. The purpose of this study was to conduct a systematic review of studies of empathy and prosocial behavior in siblings of individuals with ASD. We conducted a comprehensive literature search of studies published until March 2020. We identified 16 studies with a total of 1066 siblings that met inclusion criteria. Based on the review, we conclude that the current literature suggests that siblings of individuals with ASD exhibit normative empathic abilities and prosocial behavior.

Promoting the Social Inclusion of Children with ASD: A Family-Centred Intervention

The social isolation of children with autism spectrum disorder (ASD) is well documented. Their dearth of friends outside of the family and their lack of engagement in community activities places extra strains on the family. A project in Northern Ireland provided post-diagnostic support to nearly 100 families and children aged from 3 to 11 years. An experienced ASD practitioner visited the child and family at home fortnightly in the late afternoon into the evening over a 12-month period. Most children had difficulty in relating to other children, coping with change, awareness of dangers, and joining in community activities. Likewise, up to two-thirds of parents identified managing the child's behaviour, having time to spend with other children, and taking the child out of the house as further issues of concern to them. The project worker implemented a family-centred plan that introduced the child to various community activities in line with their learning targets and wishes. Quantitative and qualitative data showed improvements in the children's social and communication skills, their personal safety, and participation in community activities. Likewise, the practical and emotional support provided to parents boosted their confidence and reduced stress within the family. The opportunities for parents and siblings to join in fun activities with the child with ASD strengthened their relationships. This project underscores the need for, and the success of family-based, post-diagnostic support to address the social isolation of children with ASD and their families.
