The majority of individuals with autism spectrum disorder live in low- and middle-income countries and receive little or no services from health or social care systems. The development and validation of autism spectrum disorder interventions has almost exclusively occurred in high-income countries, leaving many unanswered questions regarding what contextual factors would need to be considered to ensure the effectiveness of interventions in low- and middle-income countries. This study qualitatively explored contextual factors relevant to the adaptation of a caregiver-mediated early autism spectrum disorder intervention in a low-resource South African setting. We conducted four focus groups and four in-depth interviews with 28 caregivers of young children with autism spectrum disorder and used thematic analysis to identify key themes. Eight contextual factors including culture, language, location of treatment, cost of treatment, type of service provider, support, parenting practices, and stigma emerged as important. Caregivers reported a preference for an affordable, in-home, individualized early autism spectrum disorder intervention, where they have an active voice in shaping treatment goals. Distrust of community-based health workers and challenges associated with autism spectrum disorder-related stigma were identified. Recommendations that integrate caregiver preferences with the development of a low-cost and scalable caregiver-mediated early autism spectrum disorder intervention are included.

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 socioeconomic 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.

When COVID-19 disrupted autism spectrum disorder research globally, many clinical trials of behavioral interventions pivoted to telehealth. Telehealth has the potential to increase geographic reach and improve racial/ethnic diversity in research. This matters because most autism spectrum disorder intervention studies have primarily included White, upper-middle-income families from North America and Europe. Participant homogeneity limits our ability to identify what types of intervention works in which context for which populations. Importantly, telehealth needs to “fit” the local context, and in particular, include strategies that factor in the “digital divide.” This short report details contextual considerations and pre-implementation pragmatic adaptations in two autism spectrum disorder clinical trials that include Early Start Denver Model–informed caregiver coaching in the United States and South Africa. By comparing and contrasting how implementation context informed the telehealth pivot in these two clinical trials in different hemispheres, we highlight equity considerations for adaption. The pandemic is an opportunity to understand how remote intervention can “fit” diverse contexts, while providing valid scientific results. It is however important that adaptations be documented and feasibility of the adapted approach be tracked. COVID-19-related telehealth adaptations of behavioral interventions could facilitate the development of new strategies with wider global impact. 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.

Background: Coaching caregivers to deliver Naturalistic Developmental Behavioral Intervention (NDBI) strategies to their young child with autism spectrum disorder (ASD) could help address the provider capacity barrier in sub-Saharan Africa. However, the behavioral and developmental research that underpins NDBIs is overwhelmingly drawn from high resource settings. Therefore, our understanding of joint activity routines, including play and family routines in which NDBI strategies are embedded, may have limited applicability in low resource, culturally diverse environments. Important questions remain on how to adapt NDBIs to be relevant in the family lives in these settings. This study aimed to elicit descriptions of joint activity routines from caregivers of young children with ASD in South Africa, to understand whether an NDBI-informed caregiver coaching could 'fit' within the multicultural, multilingual South African context. Methods: Four focus groups were conducted with 22 caregivers of young children with ASD who were recruited from the Western Cape Education Department autism waiting list. Data were analyzed through directed content analysis, which uses inductive methods to determine salient themes and subthemes. The predetermined initial coding classifications were based on joint activity routine categories of object-based play, sensory social routines, and family routines. Results: Participants' descriptions of caregiver-child interactions aligned with a-priori joint activity routine categories. During object-based play, caregivers engaged in turn-taking, taught developmental skills (for example cognitive, language, and fine motor skills), and participated in child-directed activities. During sensory social routines, caregivers described active, physical play, awareness of child affect, increased child expressive language, and willingness to engage with different play partners. During family routines, caregivers detailed child participation in mealtime and bath time. Conclusions: These data suggest that South African caregivers of young children with ASD use joint activity routines to engage their children and teach them new skills, thus suggesting a degree of 'fit' between South African caregiver-child interactions and an NDBI-informed caregiver coaching approach. However, more information on family routines and which caregiver interacts with the young child with ASD during these routines would help tailor these interventions for low-resource African settings.

Most autism research has been conducted in high-income countries, with participants typically from White, upper-middle-income families. Given the disparities experienced by autistic individuals living in underserved communities globally, there is a critical need for research to include individuals from culturally, linguistically, socioeconomically, and geographically diverse backgrounds to understand their unique needs. Qualitative research has the potential to describe the “lived experience” of families historically underrepresented in the autism literature. Here we describe the logistical and methodological challenges of conducting focus group discussions with 22 caregivers of young autistic children living in Cape Town, South Africa. Logistical challenges included (1) recruitment, (2) response rate, and (3) resource access. Methodological challenges included (1) participant background and experiences, (2) interpersonal dynamics, and (3) research ethics. We present recommendations based on lessons learned to reduce these challenges and improve rigorous qualitative research practices in similar low-resource contexts. Lay abstract Most of the autism research to date has been conducted in high-income countries, with children and families typically from White, upper-middle-income backgrounds. However, we know there are significant inequalities that exist which influence how autistic individuals from diverse, underserved communities can access services they need. As many of these individuals have not been included in the majority of autism research to date, there is much we do not know about these individuals’ life experiences, which are critically needed to better inform the development and implementation of care for families from historically underrepresented groups. In this article, we describe the research process we took to conduct focus group discussions with 22 caregivers of young autistic children living in Cape Town, South Africa. We specifically describe the lessons we learned in implementing these focus groups and provide recommendations aimed at how to best reduce logistical and methodological challenges moving forward to improve research conducted in similar low-resource contexts.
