ABSTRACT
BACKGROUND: While early autism intervention can significantly improve outcomes, gaps in implementation exist globally. These gaps are clearest in Africa, where forty percent of the world's children will live by 2050. Task-sharing early intervention to non-specialists is a key implementation strategy, given the lack of specialists in Africa. Naturalistic Developmental Behavioral Interventions (NDBI) are a class of early autism intervention that can be delivered by caregivers. As a foundational step to address the early autism intervention gap, we adapted a non-specialist delivered caregiver coaching NDBI for the South African context, and pre-piloted this cascaded task-sharing approach in an existing system of care. OBJECTIVES: First, we will test the effectiveness of the caregiver coaching NDBI compared to usual care. Second, we will describe coaching implementation factors within the Western Cape Department of Education in South Africa. METHODS: This is a type 1 effectiveness-implementation hybrid design; assessor-blinded, group randomized controlled trial. Participants include 150 autistic children (18-72 months) and their caregivers who live in Cape Town, South Africa, and those involved in intervention implementation. Early Childhood Development practitioners, employed by the Department of Education, will deliver 12, one hour, coaching sessions to the intervention group. The control group will receive usual care. Distal co-primary outcomes include the Communication Domain Standard Score (Vineland Adaptive Behavior Scales, Third Edition) and the Language and Communication Developmental Quotient (Griffiths Scales of Child Development, Third Edition). Proximal secondary outcome include caregiver strategies measured by the sum of five items from the Joint Engagement Rating Inventory. We will describe key implementation determinants. RESULTS: Participant enrolment started in April 2023. Estimated primary completion date is March 2027. CONCLUSION: The ACACIA trial will determine whether a cascaded task-sharing intervention delivered in an educational setting leads to meaningful improvements in communication abilities of autistic children, and identify implementation barriers and facilitators. TRIAL REGISTRATION: NCT05551728 in Clinical Trial Registry (https://clinicaltrials.gov).

ABSTRACT
BACKGROUND: Despite the high number of children living with neurodevelopmental disabilities in sub-Saharan Africa, access to early intervention is almost non-existent. It is therefore important to develop feasible, scalable early autism intervention that can be integrated into systems of care. While Naturalistic Developmental Behavioural Intervention (NDBI) has emerged as an evidence-based intervention approach, implementation gaps exist globally, and task-sharing approaches may address access gaps. In this South African proof-of-principle pilot study, we set out to answer two questions about a 12-session cascaded task-sharing NDBI-whether the approach could be delivered with fidelity, and whether we could identify signals of change in child and caregiver outcomes. METHODS: We utilized a single-arm pre-post design. Fidelity (non-specialists, caregivers), caregiver outcomes (stress, sense of competence), and child outcomes (developmental, adaptive) were measured at baseline (T1) and follow-up (T2). Ten caregiver-child dyads and four non-specialists participated. Pre-to-post summary statistics were presented alongside individual trajectories. Non-parametric Wilcoxon signed rank test for paired samples was used to compare group medians between T1 and T2. RESULTS: Caregiver implementation fidelity increased in 10/10 participants. Non-specialists demonstrated a significant increase in coaching fidelity (increases in 7/10 dyads). Significant gains were seen on two Griffiths-III subscales (Language/Communication-9/10 improved, Foundations of Learning-10/10 improved) and on the General Developmental Quotient (9/10 improved). Significant gains were also seen on two Vineland Adaptive Behaviour Scales (Third Edition) subscales (Communication-9/10 improved, Socialization-6/10 improved) and in the Adaptive Behaviour Standard Score (9/10 improved). Caregiver sense of competence improved in 7/10 caregivers and caregiver stress in 6/10 caregivers. CONCLUSIONS: This proof-of-principle pilot study of the first cascaded task-sharing NDBI in Sub-Saharan Africa provided fidelity and intervention outcome data which supported the potential of such approaches in low-resource contexts. Larger studies are needed to expand on the evidence-base and answer questions on intervention effectiveness and implementation outcomes.

ABSTRACT
LAY ABSTRACT: COVID-19 caused many autism spectrum disorder caregiver-coaching studies to move to telehealth. Telehealth can increase the diversity of people who take part in research. This matters because most autism spectrum disorder studies have included people who have resources, are White, and live in North America and Europe. When study participants are similar, it is hard to understand which interventions can help different types of people who live in different parts of the world. While telehealth may allow more people to take part in research, it needs to "fit" the local context and consider the "digital divide" because many people around the world have no access to computers and the Internet. This short report describes changes to two research studies that include caregiver coaching based on the Early Start Denver Model in the United States and South Africa. We describe how the local context, including technology and Internet access, guided the telehealth approach. By doing so, we highlight ways to make telehealth available to more people around the world. The pandemic can help us understand how telehealth can "fit" diverse places and support high-quality research. It is important that study changes are tracked and we assess how well the changes work. COVID-19 telehealth changes to caregiver coaching can result in new ways to reach more people around the world.

Digital technologies have the potential to empower individuals with autism and their families. The COVID-19 pandemic emphasized and accelerated the drive towards technology for information, communication, training, clinical care and research, also in the autism community. However, 95% of individuals with autism live in low- and middle-income countries (LMIC) where access to electricity, internet and the ever-increasing range of digital devices may be highly limited. The World Bank coined the term 'the digital divide' to describe the disparities in access to digital technologies between high-income and LMIC contexts. Here we evaluated the feasibility of six emerging technologies for autism spectrum disorders, and reflected on key considerations for implementation in LMIC contexts to ensure that we do not inadvertently widen the pre-existing digital divide.

LAY ABSTRACT: No paper to date has summarized parents' views on the functional challenges and/or strengths of their children with autism spectrum disorder. In this review we set out to perform a scoping review aiming to (a) find and compare existing research from around the globe on parental perception of functioning and (b) summarize results from these papers using the International Classification of Functioning Disability and Health-Child and Youth version framework. Since we know that the place and circumstances we live in can have a significant influence on our functioning in daily life, we were specifically interested in comparing perceptions from high-income countries and low-/middle-income countries. Two researchers conducted a comprehensive search of English studies published between 1990 and June 2016. Papers were summarized and key findings were linked to International Classification of Functioning Disability and Health-Child and Youth categories. Thirty-three studies were identified, of which most were conducted in high-income countries (n = 25/33, 76%) with only six studies in low/middle-income countries (n = 6/33, 18%). Two studies compared views from low/middle-income and high-income countries (n = 2/33, 6%). Functional themes from high-income countries included a range across the International Classification of Functioning Disability and Health-Child and Youth framework while functional themes from low-/middle-income countries were mostly focused on environmental factors. It was difficult to directly compare studies from low/middle-income and high-income countries because they investigated and discussed such different parts of functioning. We suggest that future research should use an approach that will allow researchers to directly compare functional categories in order to get a more accurate impression of the impact of context on functioning.

BACKGROUND: A lack of specialists, and insufficient infrastructure and funding to scale early interventions for autism spectrum disorder (ASD) characterize low-resource settings. Integration of early intervention methods that utilize non-specialists, and involve caregivers, into existing systems of care, offers the best hope to address such unmet needs. In South Africa, a caregiver coaching intervention, informed by principles of the Early Start Denver Model (ESDM) was adapted for delivery by non-specialist Early Childhood Development (ECD) practitioners. This study explored perceived barriers and facilitators to sustainable implementation of this approach. METHODS: Nine stakeholders including caregivers, ECD practitioners, ECD school supervisors, and certified South African ESDM therapists involved in intervention implementation were purposively sampled, and individual in-depth interviews were conducted. Interviews were transcribed verbatim and thematically analyzed. RESULTS: Implementation facilitators included: ECD practitioner ASD knowledge and ongoing supervision; a positive coaching experience; and clear illustration of intervention concepts. Implementation barriers included: complexity of some intervention and coaching concepts; logistical challenges such as time constraints and internet access; and mismatch between video content and the South African context. Facilitators to sustain the intervention included perceived positive child and caregiver outcomes; and ongoing supervision. Barriers to sustain the intervention included socio-economic contextual factors. CONCLUSIONS: In spite of the potential for positive child and caregiver outcomes from caregiver coaching, broader contextual and system-level issues such as poverty, the need for ongoing supervision, and access to local coaching materials in South African languages, may challenge sustainable implementation. Findings from this study will inform tailoring of the intervention training and supervision approach for next step evaluation.
ABSTRACT
Functional outcomes in autism spectrum disorder can be highly variable given the heterogeneous nature of autism spectrum disorder and its interaction with environmental factors. We set out to compare parent/caregiver perceptions of functioning in two divergent countries that participated in the International Classification of Functioning Disability and Health (ICF) Core Set for Autism Spectrum Disorder development study. We focused on the frequency and content of items reported, and hypothesized that environmental factors would most frequently be reported as barriers to functioning in low-resource settings. Using frequency and qualitative content analysis, we compared data from South Africa (n = 22) and Sweden (n = 13). Frequency agreement was seen in three activities and participation categories, and one environmental factor. Obvious frequency differences were observed in one environmental factors category, six body functions categories and three activities and participation categories. Only three ICF categories (immediate family, attention functions, products and technology for personal use) differed in content. Contrary to our hypotheses, few differences in perspectives about environmental factors emerged. The universality of our findings supports the global usefulness of the recently developed ICF Core Sets for Autism Spectrum Disorder. We recommend that more comparative studies on autism spectrum disorder and functioning should be conducted, and that similar comparisons in other disorders where Core Sets have been developed may be valuable.

We set out to examine key stakeholder perspectives on early detection and intervention for autism spectrum disorder (ASD) in South Africa. Early detection and intervention improves child and family outcomes and lessens long-term costs. We focused on stakeholders in the Western Cape province, one of the better-resourced in terms of healthcare. Eight senior management level stakeholders, two each from government's Health, Education, and Social Development, and the non-profit sector were identified using purposive sampling. In-depth interviews focused on key implementation- related themes. The National Integrated Early Childhood Development Policy was the most relevant to early detection and intervention. This policy, however, is not ASD specific. This lack of specificity is in keeping with an emerging theme: ASD was only seen within the context of other developmental disabilities, particularly by Health and Social Development. Specific ASD early detection and intervention may not currently align with Health and Social Development departmental goals. These departments are primarily responsible for identifying and providing services and financial support to young children with ASD. Increased ASD knowledge and local South African statistics on prevalence, burden and associated costs may alter this approach. At this time, ASD early intervention may be more closely aligned with Education department goals.

This is the third in a series of four empirical studies designed to develop International Classification of Functioning, Disability and Health (ICF) Core Sets for Autism Spectrum Disorder (ASD). The present study aimed to describe functioning in ASD (as operationalized by the ICF) derived from the perspectives of diagnosed individuals, family members, and professionals. A qualitative study using focus groups and semi-structured interviews were conducted with 19 stakeholder groups (N = 90) from Canada, India, Saudi Arabia, South Africa, and Sweden. Meaningful concepts from the focus groups and individual interviews were linked to ICF categories using a deductive qualitative approach with standardized linking procedures. The deductive qualitative content analysis yielded meaningful functioning concepts that were linked to 110 ICF categories across all four ICF components. Broad variation of environmental factors and activities and participation categories were identified in this study, while body functions consisted mainly of mental functions. Body structures were sparsely mentioned by the participants. Positive aspects of ASD included honesty, attention to detail, and memory. The experiences provided by international stakeholders support the need to understand individuals with ASD in a broader perspective, extending beyond diagnostic criteria into many areas of functioning and environmental domains. This study is part of a larger systematic effort that will provide the basis to define ICF Core Sets for ASD, from which assessment tools can be generated for use in clinical practice, research, and health care policy making.

LAY SUMMARY: The study findings support the need to understand the living experiences of individuals with Autism Spectrum Disorder (ASD) from a broader perspective, taking into account many areas of an individual's functioning and environment. The ICF can serve as foundation for exploring these living experiences more extensively by offering tools that enable wide variety of individual difficulties and strengths to be captured along with important environmental influences. As such, these tools can facilitate interventions that meet the needs and goals of the individual.

This is the third in a series of four cross-cultural empirical studies designed to develop International Classification of Functioning, Disability and Health (ICF, and Children and Youth version, ICF(-CY) Core Sets for Attention-Deficit Hyperactivity Disorder (ADHD). To explore the perspectives of individuals diagnosed with ADHD, self-advocates, immediate family members and professional caregivers on relevant areas of impairment and functional abilities typical for ADHD across the lifespan as operationalized by the ICF(-CY). A qualitative study using focus group discussions or semi-structured interviews of 76 participants, divided into 16 stakeholder groups. Participants from five countries (Brazil, India, Saudi Arabia, South Africa and Sweden) were included. A deductive qualitative content analysis was conducted to extract meaningful functioning and disability concepts from verbatim material. Extracted concepts were then linked to ICF(-CY) categories by independent researchers using a standardized linking procedure. In total, 82 ICF(-CY) categories were identified, of which 32 were related to activities and participation, 25 to environmental factors, 23 to body functions and 2 to body structures. Participants also provided opinions on experienced positive sides to ADHD. A high level of energy and drive, creativity, hyper-focus, agreeableness, empathy, and willingness to assist others were the most consistently reported strengths associated with ADHD. Stakeholder perspectives highlighted the need to appraise ADHD in a broader context, extending beyond diagnostic criteria into many areas of ability and disability as well as environmental facilitators and barriers. This qualitative study, along with three other studies (comprehensive scoping review, expert survey and clinical study), will provide the scientific basis to define ICF(-CY) Core Sets for ADHD, from which assessment tools can be derived for use in clinical and research setting, as well as in health care administration.
