Autism intervention research has not adequately addressed the needs of Black autistic children and their families, particularly those who are also immigrants to the United States. The World Health Organization designed Caregiver Skills Training (CST), a parent-mediated intervention intended to improve child social communication and behavior, to fill in the global gap of services for caregivers of young children with autism and other neurodevelopmental conditions. While CST has been implemented in Ethiopia, it has not been evaluated for Ethiopian and Eritrean immigrant families in the United States. This single-arm pilot study of CST investigated pre- and post-intervention changes in parent and child outcomes within a sample of 25 mothers of autistic children (ages 2-9 years) in Maryland, Washington, DC, and Virginia. Eritrean and Ethiopian facilitators delivered CST remotely to five parent groups. We used Wilcoxon signed-rank tests and found statistically significant improvements in parents' knowledge, skills, self-efficacy, depression, and empowerment, as well as child communication, sociability, and sensory/cognitive awareness. There were no statistically significant changes in parents' anxiety, stress, and coping, nor some subscales of the empowerment and child outcome measures. We conclude CST is a promising intervention for Ethiopian and Eritrean immigrant families in the United States. Randomized controlled trials are needed to confirm study findings.Lay abstractAutism intervention research has often not included Black autistic children and families, including those who are also immigrants to the United States. The World Health Organization designed Caregiver Skills Training (CST) because there are not enough services for caregivers of young children with autism and other neurodevelopmental conditions. CST is an intervention in which parents receive information on how to support their own and their children's needs in nine group and three individual sessions. While CST has been adapted and piloted in Ethiopia, it has not been evaluated for Ethiopian and Eritrean immigrant families in the United States. In this study, five groups with a total of 25 mothers of autistic children (ages 2-9 years) all received CST from Eritrean and Ethiopian facilitators on Zoom. The participants completed surveys about themselves and their autistic children before and after they completed CST. We found that parents' knowledge, skills, self-efficacy, depression, and empowerment, as well as their children's communication, sociability, and sensory/cognitive awareness improved after they completed CST. We did not find changes in some areas we measured, such as parents' anxiety, stress, and coping. We believe that CST might be a promising intervention for Ethiopian and Eritrean immigrant families in the United States. We recommend that more research should be done to confirm what we found in this study.

Autism spectrum disorders are potentially associated with gastrointestinal dysfunction, although the underlying mechanisms remain unclear. Recently, the oral cavity has gained attention as the starting point of the digestive tract. We aim to explore the potential association between altered oral microbiota and oxidative stress in individuals with autism spectrum disorders. We conducted a case-control study involving 54 subjects with autism spectrum disorders and 46 typically developing participants. Oral epithelial cells and saliva samples were collected to analyze oxidative stress markers and oral microbiota composition using 16S rDNA sequencing. Compared with typically developing participants, individuals with autism spectrum disorders exhibited suppressed mRNA levels of superoxide dismutase 2 and RAR-related orphan receptor α, increased H3K9me2 modifications at superoxide dismutase 2 promoter, elevated levels of 8-oxo-dG in oral epithelial cells, and a reduced ratio of reduced glutathione/oxidized glutathione (GSH/GSSG) ratio in saliva. In addition, alpha and beta diversity analyses showed significant differences in microbial richness, evenness, and intersample variation between the autism spectrum disorder and typically developing groups. Statistical analyses confirmed marked distinctions in microbial diversity and community structure between the two groups. Individuals with autism spectrum disorders show increased oxidative stress and altered oral microbiota compared with typically developing participants. While the underlying mechanisms remain unclear, these findings suggest that altered oral microbiota may be linked to oxidative stress, providing insights into autism spectrum disorder pathology and potential avenues for clinical intervention.Lay AbstractAutism spectrum disorders are linked to gut-related issues, but the exact causes are still unclear. Recent research focuses on the mouth, the first part of the digestive system, to understand how it may play a role. This study looked at how the oral microbiome (the community of microorganisms in the mouth) and oxidative stress (an imbalance between harmful free radicals and antioxidants in the body) differ in people with autism spectrum disorders compared with typically developing individuals. Researchers studied 54 people with autism spectrum disorders and 46 typically developing individuals by analyzing their saliva and oral cells. Results showed that people with autism spectrum disorders had higher levels of oxidative stress markers and noticeable differences in their oral microbiota diversity and structure. These findings suggest a potential connection between changes in oral bacteria and oxidative stress in autism spectrum disorders, opening the door for new ways to study and treat autism spectrum disorders-related health issues.

There has been limited research to date into contextual factors hindering or supporting the successful implementation of neuro-affirming practice in support for Autistic and otherwise neurodivergent adults. We used a Realist Evaluation approach to explore key contexts affecting neuro-affirming practice. A preliminary programme theory of key aspects of support was developed. Views on current practice were sought through structured interviews with 32 senior professionals in leadership roles within Health and Social Care services in Scotland. This study identified important contexts shaping the implementation of neuro-affirming practice for adults. Results indicate widespread professional support for modifying practice to better accommodate neuro-affirming ideas, and scope to achieve this. However, some contexts, including limited resources, restrictive eligibility criteria and rigid service structures, hinder progress. Growing demand for services was often viewed as a restrictive context, but it also offered a chance to rethink conventional, one-size-fits-all models and adopt neuro-affirming approaches. The study is important in addressing a current gap in research into professional perspectives of the contexts required to develop transdiagnostic, neuro-affirming approaches and pathways for Autistic and neurodivergent adults. The insights from this study may offer transferable practice approaches, applicable across different countries with similar healthcare contexts.Lay abstractDelivery of neuro-affirming adult support pathways for Autistic and other neurodivergent adults by Health and Social Care institutions can be affected by different contexts. However, there is limited research to date into the most supportive contexts for effective neuro-affirming practice. This study aimed to explore the most beneficial contexts for neuro-affirming approaches, and barriers to this. We did this by using existing research to develop a theory about the most helpful approaches to support for Autistic adults, then gathering the views of 32 senior professionals in leadership roles within Health and Social Care services to explore supports and challenges they experience in implementing these approaches. The study identified important contexts for delivery of neuro-affirming practice and how these might be achieved. Some contexts, such as limited resources, restrictive eligibility criteria and inflexible service structures, could limit progress. However, although these were often seen as barriers, they also offered a chance to rethink one-size-fits-all models and adopt neuro-affirming approaches. This study is important in addressing a current gap in research into professional perspectives of the ways neuro-affirming approaches can be developed in practice, to support Autistic and neurodivergent adults. The insights from this study may offer transferable lessons, applicable across different regions and countries.

Existing clinical outcome assessments (COAs) have limitations in capturing treatment effects in autism for those who choose to enrol in clinical research. Some COAs include items that are not relevant or equally important to all autistic people; others are not sufficiently comprehensive. Goal Attainment Scaling (GAS), which measures individual experiences against personalised goals, has been proposed as a more individualised and change-sensitive approach to assess outcomes in clinical studies. We developed a novel GAS measure for use in paediatric autism studies based on qualitative interviews with autistic adolescents, parents and clinicians. Applying a methodologically robust approach, concept elicitation interviews (N = 40) were first conducted to understand and generate a bank of personalised goals, followed by cognitive debriefing interviews (N = 39) to provide feedback on a draft GAS manual. Twenty-five personalised goals were generated for core autistic characteristics (communication, socialisation, restrictive and repetitive behaviours), as well as associated characteristics and impacts. In debriefing interviews, adolescents and parents supported the use of personalised goals and clinicians recommended using such goals in clinical studies and practice. In conclusion, GAS measures may overcome some of the challenges with existing outcome measures and complement future outcome measurement strategies for clinical studies in paediatric autism.Lay AbstractAutistic children and adolescents and their parents support the use of personalised goals as a way of measuring the effects of new treatments for those who choose to enrol in clinical research. Health professionals also recommend using personalised goals in both their research and in treatment plans. Establishing personalised goals, a process known as Goal Attainment Scaling (GAS), means identifying goals according to the needs of the individual, as opposed to using standardised outcomes for all participants. Autism is a condition with many different characteristics and degrees of impact, and the tools commonly used to measure treatment effects, known as clinical outcome assessments (COAs), have limitations. Some COAs, for example, include outcomes that are not relevant to all autistic people; others do not include enough outcomes to represent the experience of all autistic people. GAS, which measures individual experiences against personalised goals, may be complementary to existing COAs to provide an individualised or tailor-made tool to evaluate outcomes as a result of an intervention. We developed a GAS measure for researchers/health professionals to use in studies with autistic children and adolescents. Our research was based on a total of 40 interviews with adolescents, parents and clinicians, asking open-ended questions about how children and adolescents experience autism in order to understand and create a bank of potential personalised goals. We then conducted 39 further

Mobile health (mHealth; online phone or tablet-based) screening tools for autism are being increasingly used by parents, health care, and educational providers. However, it is unclear whether mHealth autism screening will improve the inequalities in autism or further help individuals already advantaged in autism care. To try to improve equity in mHealth autism screening, we conducted a modified Delphi consensus panel process with 14 panelists who were medical providers, parents, tool developers, and educational providers. Panelists participated in three asynchronous online voting rounds followed by online discussions. Panelists were provided a preliminary list of 28 recommendations for autism-screening tools that were compiled from previous qualitative interviews in the larger project. In each round, panelists were asked to vote for up to 10 recommendations from the preliminary list and discuss the voting results. After the third round of asynchronous voting, a final round of discussion with all the panelists was held live through Zoom to discuss the final asynchronous voting results. All voting and discussion took place on an online app called Slack. Voting and discussion yielded 19 recommendations in five conceptual categories: transparency, equity, access, product design and user experience, and development process. Tools adhering to these recommendations may increase equitable service use after screening.Lay abstractFamilies may use information online to learn more about autism. Families, health care, and educational providers may use online tools like checklists or web apps to screen for autism (measure whether a young child has autism symptoms or behaviors). However, we do not know whether the online autism-screening tools can be easily used by families and providers. It is possible that families who are culturally diverse, have lower education, or have lower income have trouble using online autism-screening tools. We conducted an online consensus panel with medical/educational providers, parents, and tool developers, asking them to vote and have discussions on suggestions for online screening tools for autism. The voting and discussions resulted in 19 suggestions for changes to make the tools easier to use. The top recommendations included directly linking to sources of information about autism, reading level that is less than or equal to fifth grade, and focusing on the diverse behavior/needs/strengths associated with autism.

This study examined how autistic adults conceptualize health and whether their conceptualizations differed substantively from those of their emergency contacts (people who helped with health or healthcare management). We conducted semi-structured interviews with 10 dyads of autistic adults and emergency contacts. A thematic analysis with deductive and inductive codes identified four main themes: (1) health is subjective well-being; (2) healthy is the absence of pain; (3) challenging neurotypical norms; and (4) differences in health definitions were smaller than perceived. Autistic participants and emergency contacts endorsed the first two themes. Only autistic participants discussed the third theme. Despite broad agreement about what "healthy" means, emergency contacts perceived significant differences between their definition of health and that of their autistic counterpart. The data suggest these differences were primarily about health behaviors. We present a model for a Personalized Health Ecosystem, describing important factors for personal conceptualization of health among autistic adults. These findings demonstrate the need for individualized care, for healthcare providers to partner with autistic patients to best support their health, and for education programs for providers who work with this community.Lay AbstractAutistic adults experience worse health and have a higher risk of mortality on average. Many autistic adults say that physicians and other healthcare providers do not understand autism and autistic people's needs. This study wants to understand how autistic adults specifically understand healthy habits as this could inform better care. We interviewed 10 autistic adults and their emergency contacts (family or friends who help them with healthcare decisions) about how they understand health and what they do to be healthy. We compared what the two groups said. Both autistic adults and their emergency contacts said that being healthy could look different for everyone. Beyond physical health, participants talked about mental, financial, and spiritual health. Participants described "healthy" as the absence of pain, though the fact that you can be in pain and healthy was mentioned. Autistic adults and their emergency contacts described health similarly. Autistic adults, however, shared more non-traditional health-promoting behaviors. These findings can help healthcare providers better understand how to work with autistic patients. Physicians should work with autistic patients on how to be healthy, rather than assume that autistic adults do not understand health.
