Abstract
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.

Introduction
Worldwide, there are approximately 150 million children and youth under the age of 18 years with a disability including neurodevelopmental disabilities (NDD)[1]. A diagnosis of NDD can include autism spectrum disorder, attention-deficit and hyperactivity disorder, cerebral palsy, Down syndrome, or fetal alcohol spectrum disorder [2, 3]. As children and youth with NDD transition to adulthood, they may experience multiple challenges as they navigate developmental trajectories including exploring options for post-secondary education or accessing health services in the adult care system [4, 5]. Individuals with NDD may seek support from their families as they transition into adulthood, including support with personal care and activities of daily living [4,5,6]. Many families are well positioned to provide the most optimal support given their history, knowledge, and familiarity of the family member’s care and social needs throughout the individual’s life [6].
In addition to parental support, in families with more than one child, siblings may also emerge as another source of support for an individual with NDD. Every sibling relationship is unique with differing levels of emotional closeness and expectations of each other [7]. Sibling relationships can evolve or change over time based on the needs, roles, and commitments of the whole family [8]. When a sibling has NDD, their sibling may choose to provide support. There are four main types of support: 1) concrete support that includes acts of practical assistance, 2) emotional support that involves acts of empathy, 3) advice support that encompasses acts of provision of information, emotional reassurance, and guidance, and 4) esteem support that includes the reinforcement of the personal worth of an individual [10]. Sometimes, there is an implicit expectation from parents that a sibling will be actively involved in supporting the family member with NDD [9]. Given this, siblings may need support for different roles that they can assume in supporting their brother or sister [10, 11].
Programs are available to support siblings in roles that they may assume. The broad aims of many of these programs include: 1) providing information about NDD, 2) creating sibling communities to connect and share experiences with each other, or 3) connecting siblings to resources and services to assist them in their supporting role [12, 13]. Programs that have been developed have often been tailored to siblings of different ages. Sibshops, for example, was developed in the USA for siblings ages 8 to 13 years old to learn strategies to address situations with their sibling with a disability [12]. Some programs may be targeted for the whole family with specific sessions for siblings to learn about NDD [14] or to learn strategies to connect with the sibling with NDD. In these programs, parents can be trained on how to reinforce these strategies at home [15].
While descriptions of varied programs exist across the literature, there is limited understanding of the impact and outcomes of these programs on siblings of individuals with NDD. This scoping review was conducted to identify and map the characteristics of and outcomes for participants in programs designed to prepare siblings in their future roles to support their brother or sister with NDD. A preliminary search on the JBI Database of Systematic Reviews and Implementation Reports, Cochrane Database of Systematic Reviews, PROSPERO, PubMed, and CINAHL did not identify any reviews on this topic.
Review Questions
This scoping review was conducted to answering the following two questions:
-
i.
What are the characteristics of programs designed to support siblings of an individual with NDD (e.g., purpose, description, eligibility criteria, length, activities, service provider, and delivery) for siblings of individuals with NDD?
-
ii.
What are the outcomes for siblings of individuals with NDD participating in the programs?
Methods
This scoping review was conducted according to the Joanna Briggs Institute (JBI) methodology for scoping reviews [16]. The protocol with details of the full search strategy for this review has been published [17]. This report of the scoping review results was written using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist [18].
Patient and public involvement
An integrated knowledge translation approach was used in this scoping review, which is an approach to doing research with knowledge users as equal partners with researchers [19]. We partnered with the Sibling Youth Advisory Council (SibYAC) comprised of six young adults who have a sibling with a disability. The SibYAC identified the importance of the research questions addressed in this review and the program outcomes (e.g., knowledge acquisition, skill development, and empowerment). The SibYAC also reviewed the preliminary findings, provided recommendations to interpret the results, and suggested knowledge translation and dissemination activities to share these results with the community.
Search strategy
An initial limited search was conducted on PsycINFO to identify relevant articles. The text words contained in the titles and abstracts of relevant articles, and the index terms to describe these relevant articles were used to develop a full search strategy for PsycINFO. The full search strategy was then adapted for each included database. The reference list of all included sources of evidence was screened for additional relevant studies. Articles published from database inception to December 20, 2020 were included.
Information sources
The databases that were searched included PsycINFO, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Sociological Abstracts, Education Resources Information Center (ERIC), EMBASE, Web of Science, MEDLINE (Ovid), and Sport Discus.
Study of evidence selection
Following the search, all identified citations were collated and uploaded into Covidence, systematic review software (Veritas Health Information, Melbourne, Australia), and duplicates were removed. Following a pilot test, titles and abstracts were screened independently by two reviewers (LN and JB) against the inclusion criteria. Potentially relevant sources were retrieved in full with citation details. The full text of selected studies was assessed in detail against the inclusion criteria by two independent reviewers (LN and JB). Reasons for exclusion of full text studies were recorded. Any disagreements between the reviewers at each stage of the selection process were resolved through discussion or consultation with a third reviewer (MK).
Inclusion criteria
Participants
This review focused on identifying and describing programs with participants who are siblings of an individual with NDD. For this review, NDD is defined as a group of congenital or acquired long-term conditions that resulted from an impairment of the brain and/or neuromuscular system and can lead to functional limitations [2]. In this review, no age limits were applied for the population of the siblings and siblings with NDD and may vary, including children, youth, and adults. In this review, we refer to the siblings of individuals with NDD who participated in the programs as siblings. However, we recognize that these siblings may have had disabilities themselves that were not disclosed in the included studies.
Concept
This review included studies that described programs designed to support siblings in their roles. The outcomes of these programs were operationalized to include 1) knowledge acquisition or skill development for the siblings themselves (e.g., knowledge about NDD, sharing and learning experiences about the strengths and challenges in the sibling relationship, development of coping strategies, and problem-solving skills) and 2) empowerment to train siblings to learn skills that they can apply with their sibling with NDD (e.g., how to modify certain behaviors of the sibling with NDD and how to enhance social communication skills in the sibling relationship). Studies about programs that focused only on therapy or support for siblings without reference to support for the individual with NDD have been excluded.
Context
The context of this review included all settings that deliver programs for siblings of individuals with NDD, such as school, rehabilitation, healthcare, or community settings, in any country. Only studies published in English were included.
Types of Sources
This review included all study designs such as experimental and quasi-experimental study designs, randomized controlled trials, non-randomized controlled trials, before and after studies and interrupted time-series studies, single-case studies, descriptive studies, observational studies, qualitative studies, and mixed methods studies.
Data Extraction
An initial pilot test of the data extraction for approximately 10% of the included studies (n = 7) was performed independently by two reviewers (LN and JB) using a data extraction sheet. Based on this initial pilot test, the data extraction tool was modified to provide additional clarity of the information that would be extracted (see Supplementary File 1 for an updated data extraction sheet). For the remaining included studies, data were extracted by one reviewer (LN) and checked by a second reviewer (JB). Disagreements between the reviewers during this check of the extracted data were resolved through discussion or consultation with a third reviewer (MK). The authors of included articles were contacted to request missing or additional data based on the data extraction sheet.
Data Analysis and Presentation
The extracted data are presented in tabular form that provides a comprehensive overview about sibling programs based on the information outlined in the data extraction form. To address the two research questions of this review, an accompanying descriptive narrative summary is provided in this report.
Results
There were 5674 non-duplicate articles retrieved through the database searches. No additional studies were identified from the reference lists of included studies. After title and abstract screening, 5420 articles were excluded. There were 254 articles reviewed in full text with a disagreement proportion of 20.8% that were resolved by discussion and/or with a third reviewer, and 196 articles did not meet the inclusion criteria. A total of 58 articles were included in this review (see Fig. 1), representing 54 distinct sibling programs.
Characteristics of Included Studies
The included articles reported studies from Canada (n = 3), USA (n = 42), UK (n = 4), Ireland (n = 1), Turkey (n = 1), Norway (n = 1), Sweden (n = 1), Greece (n = 1), Taiwan (n = 1), Cambodia (n = 1), and Australia (n = 2). The articles reported on studies that were conducted from 1975 to 2020, with more than half of the included studies published since 2012 (n = 30). Descriptions of included studies are presented in Table 1.
Participants
There was a total of 1033 sibling participants (n = 399 males and 553 females). Sibling participants ranged in age from 4 to 67 years, with 49 studies with participants younger than 18 years old, three studies with participants 18 years or older, and two studies with a mixture of participants younger and older than 18 years of age (refer to Table 1). There were 22 studies that included participants of siblings with one NDD, including 18 studies that focused on autism spectrum disorder and three studies that focused specifically on attention deficit-hyperactivity order, cerebral palsy, and Down’s syndrome. The remaining studies had participants of siblings with varying health conditions including intellectual and developmental disorders or referred to disabilities as a broad term. The birth order between sibling participants and the sibling with NDD was reported by 37 studies, in which 21 studies had all sibling participants who were older than the sibling with NDD, two studies had sibling participants who were younger than the sibling with NDD, and 12 studies that reported a combination of sibling participants who were older and younger than the sibling with NDD. There were two studies that each reported two twins and one triplet. Detailed participant characteristics in each study are provided in Supplementary File 2.
There were 27 programs that included parental involvement, for example, by completing questionnaires [34, 41, 77, 88, 102, 123, 127, 138] or they were trained to be observers of their child’s performance [37]. Some parents were participants in the program [14, 15, 56, 60, 68, 107, 139, 140, 142], with parent training programs [139], information sessions [142], parent-specific sessions with some parent-sibling sessions [14, 56, 60, 68], or as part of a family training program [15, 107, 130].
Concept
There were 27 programs that focused on the outcomes of knowledge acquisition or skill development by the siblings for themselves and 31 programs that focused on the outcome of empowering siblings to be trained in specific skills that they can then teach their sibling with NDD. Programs that focused on knowledge acquisition or skill development for siblings were first studied in the 1980s, while programs that focused on empowering siblings have been available since the 1970s (see Fig. 2). For programs about knowledge acquisition or skill development for siblings, the program characteristics are presented in Supplementary File 3 and the outcomes and key findings are presented in Supplementary File 4. For programs about empowering siblings by training them with skills that they can teach to their sibling with NDD, the program characteristics are presented in Supplementary File 5 and the outcomes and key findings are presented in Supplementary File 6.
Across All Sibling Programs
Mode of Delivery
Most programs were delivered in person (n = 57). Only one program offered two in-person meetings before incorporating group meetings by telephone [67].
Duration and Frequency
The length of the program varied depending on the purpose of the program. For programs that were focused on providing knowledge or skills for the siblings themselves, the sessions were often offered as consecutive weekly sessions, for example, 6 to 10 weeks for approximately half an hour to 2 h [15, 21, 50, 63, 67, 68, 71, 77, 84, 96, 102, 116, 123, 125, 127]. Some programs offered knowledge or skills acquisition for the siblings themselves in a short timeframe, for example, with all sessions in 1 day [56] or 2 days [25••], or for 5 days as part of a summer camp [142]. The programs that trained siblings about specific skills to be applied to the relationship with the sibling with NDD also varied in length. Most programs were delivered with 1–2 sessions per week, between 5 to 22 weeks with sessions ranging from 15 min to 2 h [31, 32, 34, 36, 37, 41, 54, 70, 87, 96, 134].
Program Developers
There were 35 studies that described the program developers, with 17 programs focused on providing knowledge or skill development for siblings [12, 14, 15, 21, 25••, 39, 60, 63, 67, 71, 77, 84, 102, 116, 123, 125, 140, 142] and 17 studies that aimed to train siblings to apply skills with their sibling with NDD [32, 41, 46, 47, 54, 70, 87, 88, 96, 126, 128, 130, 134,135,136,137,138]. For programs that aimed to provide knowledge or skill development for the siblings, the developers of the program were primarily from the study authors [14, 21, 60, 84] or organizations that focused to support siblings of individuals with disabilities such as the Sibling Leadership Network in the USA [25••] or Sibs in the UK [71]. There were no studies that explicitly described whether siblings of individuals with NDD were part of the team of developers and the roles that they might have had. Some studies referred to elements of a program based on previous studies about sibling studies [14, 77, 102, 140, 142]. For example, a randomized controlled trial [77] that evaluated a sibling program developed the program based on a study by Kryzak and colleagues [84]. Similarly, programs that aimed to empower and train siblings to teach skills to their sibling with NDD were often based on existing literature or intervention programs [32, 41, 47, 54, 70, 87, 88, 96, 128, 130, 134–138].
Program Facilitators
There were 48 studies that described program facilitators [14, 15, 20, 21, 25••, 31, 32, 34, 36, 38, 39, 41, 47, 50, 51, 56, 60, 63, 67, 68, 70, 71, 77, 84, 87, 88, 96, 102, 107,108,109,110,111, 116, 123, 125, 128,129,130, 132,133,134,135, 137,138,139,140, 142]. The program facilitators included individuals from a variety of backgrounds including undergraduate students [32, 36], graduate students [14, 15, 21, 31, 68, 77, 84, 116, 123, 130, 138,139,140], adult siblings of individuals with intellectual and developmental disabilities [25••], healthcare professionals (e.g., social worker, nurse practitioners, nurses, psychologists, and therapists) [34, 39, 51, 56, 63, 67, 87, 102, 107, 116, 123, 128, 140, 142], community center staff [111], special education teachers or staff members at schools [71, 84, 109]. For some programs, the study authors were also the program facilitators [31, 38, 41, 47, 70, 88, 96, 133,134,135, 138]. Some programs offered opportunities for students to be volunteers and facilitate sessions alongside licensed professionals [84, 111]. While some programs required the facilitators to be licensed professionals, there were programs that also required the facilitators to receive training [56, 71, 84, 134] such as an e-learning course for approximately 1 h with a 2-day workshop [56] or weekly meetings with discussion, coaching, and feedback [134]. One study provided suggestions of facilitators with specific educational backgrounds that might be a good fit to run certain sessions of a program, for example, discussion sessions can be facilitated by teachers, parents, individuals from community organizations, or the siblings themselves [129].
Context
Among the programs that focused on knowledge acquisition and skill development for siblings, there were 16 programs that described the setting context. These programs were conducted in a variety of settings including at a community center [21, 50, 111], medical center [39, 56, 127, 140] or clinic [97], school [71], or camp [142].
For programs that were focused on training the siblings to learn and apply skills with their siblings with NDD, there were 27 programs that listed the setting context [20, 31, 32, 34, 36,37,38, 41, 46, 47, 54, 70, 76, 87, 88, 108,109,110, 126, 128, 132,133,134,135,136,137,138,139]. The majority of these programs was conducted in the participant’s homes [20, 31, 36,37,38, 41, 47, 54, 70, 76, 87, 88, 108,109,110, 126, 132,133,134,135,136,137,138]. Some programs had sessions that were held in multiple settings. Programs were also held at a community center [32], recreational camp [139], treatment center [108], behavioral management center [128], or at a clinic [34].
Programs with Outcomes of Knowledge Acquisition and/or Skill Development for the Siblings
Purpose
The purpose of the programs was focused on the outcomes of knowledge acquisition and/or skill development for the siblings. To achieve these purposes, there were six programs that provided general information about the developmental or health condition [51, 97, 111, 123, 129, 142]. Other programs provided information tailored to a specific condition, with four programs providing information about autism spectrum disorder [21, 77, 84, 127]. Inherent to many programs to acquire knowledge was a goal of creating opportunities for siblings to connect with peers, for example, to discuss the NDD of their siblings with other siblings [56, 123] or to share their lived experiences of growing up with a sibling with NDD. In addition to knowledge acquisition, several programs included skill development components that included opportunities for siblings to develop coping skills [77, 102] or problem-solving skills to enhance their relationship with their sibling with NDD [21, 67, 77]. For example, programs offered opportunities for siblings to share their lived experiences and learn from each other about how to address certain situations [12, 51, 56, 97, 102].
Description of Program Activities
The programs included multiple sessions with a dedicated focus for each session: introductions, structured activities, and concluding session. For the introduction sessions, the content might include icebreaker activities to develop group cohesiveness and rapport [63, 77, 125]. After the introduction sessions, there were multiple sessions with structured activities. These activities included providing knowledge about NDD [50, 56, 60, 63, 67, 68, 84, 116, 123, 125, 140, 142] and learning how to problem-solve and address challenges with a sibling with NDD [14, 15, 51, 63, 77, 84, 125]. One program included activities for adult siblings to learn about disability policy, advocacy, peer support, as well as national, state, and local resources [25••]. Some of the structured activities were focused on further development of group rapport such as recreational and social activities [12, 14, 50, 140] or arts and crafts activities [50, 111, 125]. For the concluding session, some programs ensured that the last session was a celebration, such as with a graduation [14, 68], presentation of diplomas [67], or fun activity chosen by the siblings [125]. Details about the purpose and activities for each program are presented in Supplementary File 3.
Program Outcomes and Key Findings
The programs focused on the outcomes of knowledge acquisition and skill development for the siblings. The following information is an overall summary about the key findings from the programs on siblings. The siblings acquired knowledge from these programs in which they experienced an increase in.
understanding about disabilities after the program [12, 14, 21, 51, 63, 67, 71, 84, 97, 125, 127, 140, 142], and some siblings learned about new resources that they could access [25••]. By participating in these programs, siblings identified that they found a support network because they were able to connect with other sibling participants [84, 102, 111, 142]. The siblings also experienced outcomes related to the development of skills for themselves, such as development of self-esteem [51, 111, 142], development of coping skills, [3, 49], decrease in stress [20], improvement in mood [18], and feelings of empowerment [25••]. However, one study identified that the siblings experienced an increase in self-esteem and development of coping strategies but these outcomes were not maintained at follow-up [116]. Details about the program outcomes and key findings for each study are presented in Supplementary File 4.
Programs to Empower Siblings to Teach Skills to Their Sibling with NDD
Purpose
The programs focused on empowerment by training siblings to learn general skills that they can then teach their sibling with NDD. The programs primarily trained siblings to learn skills to interact with their sibling with NDD, for example, how to deal with aggression or improve their communication skills with nonverbal and verbal cues [20, 32, 34, 36, 47, 54, 70, 76, 88, 128, 130, 132,133,134,135,136,137,138]. Programs that aimed to enhance social communication skills between the siblings with and without NDD also had specific procedures, such as joint attention intervention [54], milieu teaching procedures [70], natural learning paradigm [128], reciprocal training intervention [138], and script fading procedure [20]. One program focused on addressing sibling conflict, in which both the sibling with and without NDD can learn about social and emotional factors that can help to resolve conflicts [88].
Description of Program Activities
The programs included activities to train the siblings to teach their sibling with NDD to learn skills. The following information describes the format and content of these activities to teach these skills to the sibling. The siblings were introduced to the skills using a variety of methods including discussions with the trainer [31, 32, 37, 54, 87, 88, 109, 110, 126, 130, 132,133,134,135, 137,138,139]; teaching materials such as visual text on a PowerPoint, written manual, or handouts [47, 70, 132, 138]; completing homework sheets [34]; reading stories [135,136,137] or using puppets [136, 137] to illustrate the skill; videos about how the sibling could prompt their sibling with NDD to use the skill and how to praise their sibling for using that skill [41, 47, 108, 110, 126, 128]; modeling the skill with the sibling with NDD by a trainer [31, 76] or parent [107] while the sibling observes; or having a parent explain the skill as a story to the sibling [135]. After the sibling learned the skill, some programs offered opportunities for the sibling to apply how they could teach the skill through verbal practice, questions, and application activities [47, 139], role-play with the trainer with feedback [54, 70, 87, 108, 109, 128, 130, 133, 134, 136, 138], and additional prompts are provided by the trainers during the teaching sessions as needed [54, 133]. Details about the purpose and activities for each study are presented in Supplementary File 5.
While all programs were focused on empowering and training the siblings, there were eight studies that reported about programs with components for other family members. Some programs offered a parent component, such as parent information sheets [116, 123] or an information session [140, 142]. There were four family programs, with sessions for parents and siblings to interact and siblings could share the challenges that they experienced with their parents [14, 56, 60, 68]. There was a program that included both parents and siblings, where parents watched the videotapes that were recorded by the siblings, and there was a discussion about the topics discussed in the videotapes [140]. In addition to a parent component, there was also a component for the siblings with NDD. There were two programs that offered separate sessions that were conducted simultaneously, with a session about social communication for the siblings with autism spectrum disorder and one session for the sibling [77, 84].
Program Outcomes and Key Findings
The programs focused on the outcomes of empowerment in which siblings could successfully carry out the skills that they were trained in [31, 32, 34, 37, 41, 46, 54, 76, 87, 96, 108,109,110, 126, 128, 130, 132, 133, 138]. These skills were primarily focused on the development of positive social behaviors, such as sharing, asking or giving help and compromising [41], setting and monitoring goals [87], or providing tangible reinforcement of a behavior from the sibling with NDD[54, 87]. Other skills that the siblings learned include teaching the sibling with NDD of basic self-care skills [96] or how to communicate with their sibling with NDD [47]. Some siblings stated that the skills were easy to learn [41, 128], while other siblings described that the skills were hard to learn [138]. Some studies indicated that these skills were maintained at follow-up [34, 70, 87, 133, 134]. While learning these skills, the siblings reported increases in self-confidence [38] or feeling enjoyment from spending time with their sibling with NDD [70]. For some siblings, the training was found to be associated with modest positive changes in the interactions between siblings with and without NDD [107, 135]. Two studies found that the skills that siblings learned were generalizable to other settings [87, 108] or with other children with NDD [110]. Details about the program outcomes and key findings are presented in Supplementary File 6.
Discussion
This review focused on programs to support siblings in their future roles, and these programs aimed to provide knowledge acquisition or skill development for the siblings themselves, or to provide training about specific skills that can be applied with the sibling with NDD. Recent trends about sibling programs were identified in this review with an increase in the availability of sibling programs that focused on knowledge development and skill acquisition as well as empowerment. Starting in 2002, there has been an increase in the involvement of the whole family, including both parents and siblings, in programs. This review identified four studies, referring to two programs, that included the parents and/or caregivers as participants alongside the siblings [14, 56, 60, 68]. In both programs, there were specific sessions for siblings and parents with integrated sibling-parent sessions. Furthermore, there was only one program included in this review that provided a combination of in-person and telephone meetings [67], with all remaining programs that were delivered in-person. In light of the COVID-19 pandemic, some sibling programs have been adapted to be delivered online [148]. Moving forward, there could be considerations about different formats to delivery sibling programs with both online and in-person approaches in order to meet the needs of siblings of individuals with NDD.
In our review of online resources [149], siblings identified in blogs and interviews about the importance of first acquire knowledge about the NDD of their sibling before they could learn specific skills. In addition to knowledge, the siblings also learned about coping skills to address the challenges that they experienced in their sibling relationship. For some siblings, the programs provided a network where siblings could connect and share similar experiences about their relationship with their sibling with NDD. A combination of supports for siblings that come from family, school, peers, and healthcare professionals can be helpful to enhance their ability to cope with certain situations and enhance a positive sibling relationship [150]. It is, therefore, important to consider how programs may need to foster opportunities for siblings to acquire knowledge about NDD and develop skills for themselves, such as coping skills, before providing information about how to take on future supporting roles.
In addition to knowledge and supports for siblings, programs also trained the siblings to learn specific skills to apply with their sibling with NDD. Sibling training programs taught specific skills, such as how to communicate with the sibling with NDD using nonverbal and verbal cues, and were similar to sibling programs described in recent systematic reviews [151•, 152•]. These reviews focused on how siblings have been involved as a playmate, model, or instructor in interventions for children with a disability [151•] or as intervention agents in programs specific to children with autism spectrum disorder [152•]. This review further builds on existing literature by describing the outcome of empowerment when siblings learned about specific skills that they can teach to their sibling with NDD.
Value of Sibling Programs
Meetings have been held with the SibYAC about the value of sibling programs and the relevance of the review findings to siblings and their families. The findings of this review indicated that siblings and families valued programs to support siblings in acquiring knowledge, developing skills for themselves (e.g., coping strategies), and being trained to apply skills with their sibling with NDD (e.g., using verbal and nonverbal cues). In programs that involved both parents and siblings, [13, 28,29,30], the activities during these sibling-parent sessions included the siblings creating videos that the parents viewed [14] or for the siblings to share their challenges to their parents and for parents to practice their communication skills [56, 60]. When siblings are preparing for their future roles, there should be planned conversations with the whole family [153]. Despite the important roles that the siblings might have in the future of their sibling with NDD, there are often no formalized plans [154]. Siblings have identified that there should be clear plans in place in order for them to be prepared for their future roles [154,155,156].
This review identified that sibling programs took place in a variety of settings depending on the purpose of the program. Most programs that were focused on empowering and training siblings about skills to teach their sibling with NDD were conducted at home. Programs that trained the whole family were also conducted at home [15, 107, 130]. It is important to consider how the home environment may be a good fit to conduct certain programs that could involve supporting the sibling and the whole family. The person and the environment can be viewed as a bi-directional transactional process that influences each other [157]. A good fit between the person and environment can positively influence the outcomes of the programs for both the siblings and the siblings with NDD [157]. The SibYAC shared that the environment is not only comprised of the physical home environment but also the family context, similar to what has been identified by other researchers [158]. The siblings have an important role in the family and while they may not physically live in the family home at certain times [159], they should have opportunities and space to discuss roles that they would like to have.
Strengths and Limitations
A strength of this review is that there was a clear and transparent process to conduct this review, in which protocol was published prior to conducting data analysis. The published protocol and final report were written according to the JBI methodology for scoping reviews [16, 160] and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist [18]. When conducting scoping reviews, it is important that the protocol is developed a priori and that the aims are transparent and reproducible [161]. Another strength of this review is the novel contribution of mapping the availability and type of sibling programs that have been published over time. The growth in the number of available programs for siblings has significance in understanding how siblings can be involved with their sibling with NDD in different ways, such as modifying certain behaviors so that both the sibling and sibling with NDD could communicate with each other.
This review has an additional strength by providing a methodological contribution about how an integrated knowledge translation approach was used to partner with the Sibling Youth Advisory Council throughout the process of conducting this scoping review [19]. This partnership informed the relevance of the research questions, reporting of program outcomes (e.g., knowledge acquisition, skill development, and empowerment), and implications of the findings. The Involvement Matrix [162] was used as a conversation tool about roles and responsibilities, and the SibYAC members preferred to have the roles of being a listener in which they provided with information, a co-thinker in which they were asked to provide an opinion, or an advisor in which they provided (un)solicited advice [162]. Regular updates were provided to the SibYAC at each stage of the review, and the SibYAC shared their perspectives about the implications and value of sibling programs identified in this review.
One limitation of this review is that there were some articles that could not be retrieved in full text, although the corresponding authors and relevant journals were contacted up to three times. However, all non-retrievable articles were published prior to 2013 and may no longer be available. A second limitation is the use of the term NDD in our search strategy, which was defined by healthcare professionals in the context of the traditional medical model [3]. However, since the publication by Morris and colleagues [3], we recognize the shift toward expanding the definition of NDD within a biopsychosocial model that focuses on the development of individuals with NDD within an environment that changes over their life course [163]. There are multiple contextual factors other than the medical diagnosis or impairments that can influence the life of an individual with NDD [164]. A third limitation is that some information was not reported in the articles, such as gender of participants or developers of the program. The synthesis of the findings could only be based on the information that was reported in the studies. A fourth limitation is that the synthesis of extracted data to answer the second question in this review about the outcomes for the siblings of individuals with NDD was only provided descriptively. A fifth limitation is that only programs published in English, and there may be other existing programs for siblings offered in different languages.
Future Directions
There are several areas for further research that can be conducted to enhance programs for siblings of individuals with NDD. Firstly, it was striking that there was limited information identified in these programs about how siblings can prepare for their future roles. While many programs in this review provided knowledge about NDD to siblings, there was only one program that described providing resources for the siblings [25••]. The siblings participating in programs may wish to access additional resources for their learning. For example, a review of sibling resources was recently synthesized across children’s hospitals, organizations, and treatment centers in Canada that could be shared with siblings [149]. Existing programs could consider how to expand the content of their programs with resources that the siblings may refer to. However, these programs may provide resources to siblings but did not report these resources in their publications. The reporting of these details could be included in future studies.
Secondly, this review highlighted that there were no studies that explicitly described whether siblings of an individual with NDD were co-developers. However, there was one study that identified siblings of an individual with NDD who were facilitators of the program [25••]. Future opportunities could be provided to siblings of individuals with NDD to be engaged as partners in sibling partners with different roles, such as being a co-developer or facilitator, that would be valuable and meaningful [165].
Thirdly, for future sibling programs that are conducted, there could also be an exploration about the evaluations of the effectiveness and social validity of the programs. In a recent systematic review about programs for siblings of children with a disability, the effectiveness of the programs could not be determined due to the variability in the ages of participants, diagnoses of the siblings with a disability, duration of the study, content and structure of the training in the program, and reported outcomes [151•]. A different systematic review of intervention programs that involved siblings [152•] assessed the social validity, including social significance of the goals, social acceptability of the procedures, and social importance of the outcomes. Future programs could measure the social validity using similar methods.
Finally, the majority of programs identified in this review was conducted in the USA. Based on a recent scoping review, there are few programs available for siblings of individuals with NDD in low- and middle-income countries [166]. Although most sibling programs are available in high-income countries, a recent study identified that sibling support provider organizations in Australia, Canada, New Zealand, the UK, and the USA were operated with minimal staffing and funding [148]. While there may be programs offered in other countries besides those included in this review, these programs have not been published. Further research and allocation of funding should be considered about how to offer and publish about these programs to support siblings and the whole family of individuals with NDD across countries.
Conclusion
This scoping review synthesized the characteristics and outcomes of programs for siblings to support them in their future roles with their sibling with NDD. This review identified that there is an increasing number of sibling programs to provide knowledge or acquisition of skills for the siblings themselves, as well as to train siblings to learn and apply specific skills with their sibling with NDD. Findings from this review can inform future directions for the development and enhancement of sibling programs.

(Findings from this systematic review identified that siblings of individuals with a disability can have various roles in interventions, such as a trained playmate, instructor, or model that have led to positive outcomes. Further research is needed to understand the impact of involving siblings in interventions for individuals across different ages and different diagnoses.•)

(Findings identified that neurotypical siblings were able to successfully deliver the intervention after appropriate training and feedback, which led to positive outcomes for the siblings with autism spectrum disorder and improvements in the interactions between siblings. Future research should be conducted about the appropriate selection of neurotypical siblings to deliver the intervention with a better reporting of variables in the home environment that could affect the delivery of the intervention.)
