There are marked racial and ethnic disparities in diagnosis and services for individuals on the autism spectrum, yet race and ethnicity are underreported and underexamined in autism research. The current study examines the reporting of race and ethnicity and the inclusion of participants across racial and ethnic groups in studies included in a large-scale systematic review of autism intervention research (1990–2017). Trained research assistants reviewed 1013 articles and extracted data on the reporting of race and ethnicity data and the inclusion of participants from different racial and ethnic categories from each article. Only 25% of the articles reported any data on race and ethnicity and reporting over time has slowly increased across the 28 years of the review. Descriptive statistics suggest that race and ethnicity reporting varied by study design, intervention, and outcomes. In studies with reported data, White participants had the highest rate of participation (64.8%), with a large gap between the next highest rates of participation, which were among Hispanic/Latino (9.4%), Black (7.7%), and Asian (6.4%) participants. The lack of reporting and the limited inclusion of participants across minoritized racial and ethnic groups are concerning and suggest a need to examine practices in autism research from planning to dissemination. Lay Researchers who study autism-related interventions do a poor job reporting data related to the race and ethnicity of autistic individuals who participate in their studies, and of those who do report these data, the participants are overwhelmingly White. This is problematic for many reasons, as we know little about how interventions are meeting the needs of culturally and linguistically diverse populations, and we assume that interventions are effective for all when they have been developed and validated primarily with and for White children. This study examined the reporting patterns of autism intervention researchers whose work was included in a large-scale systematic review of the intervention literature published between 1990 and 2017. We found that only 25% of studies (out of 1,013 included in the review) included data related to the race and ethnicity of their participants, with minimal change in reporting patterns across the years. In studies with reported data, White participants had the highest rate of participation, with a large gap between the next highest rates of participation among Hispanic/Latino, Black, and Asian participants. Other race and ethnicity groups had very low representation. This study includes additional analyses which examine how the reporting patterns and the inclusion of racially and ethnically diverse participants varies across study types, interventions, and outcome areas. Reporting this data is merely a starting point to begin to address the many disparities in autism-related healthcare, education, and research practices, and this article includes broader implications and next steps to ensure the field becomes more equitable and inclusive.

Despite an emphasis on identifying evidence-based practices among researchers and using evidence-based practices among professionals in the field of education, there are still problems with uptake and implementation in real-world settings. This lack of diffusion of practices is evident in educational programming for children with autism spectrum disorder (ASD). One solution is to use an iterative process to develop interventions in which researchers work in collaboration with the end users to test and refine interventions. However, there are very few guidelines for developing feasible and effective interventions through these iterative processes. This article provides a description of the iterative process used to develop the Advancing Social-Communication and Play (ASAP) intervention, a supplemental program designed for public preschool classrooms serving students with ASD, and examples of how data from the sequence of iterative design studies shaped the intervention development. The research team offers guidelines for other researchers looking to engage in intervention development using an iterative process in the context of partnerships with end users, including suggestions for planning and executing an intervention development grant.

Assessing implementation of comprehensive treatment programs is a multifaceted process that should extend beyond measuring solely treatment fidelity. The purpose of this article is to describe and demonstrate a thorough process for assessing implementation and receipt of a comprehensive treatment program for students with autism spectrum disorders in high schools. The Center on Secondary Education for Students With Autism Spectrum Disorders (CSESA) developed a profile and index approach to assess implementation of seven features related to the CSESA intervention process and content. In a cluster-randomized trial, the CSESA implementation profile captured information about diverse features of implementation, and this index successfully differentiated between intervention and control schools. A multifeatured implementation profile and index is an important step forward for examining and implementing comprehensive treatment programs in educational settings.

Transitioning Together is a multi-family intervention designed to support families of adolescents on the autism spectrum as they prepare for the transition to adulthood. Questions remain regarding its wide-scale adoption and implementation in real-world settings such as high schools. We examined student, teacher, and school-level facilitators and barriers to adopting and implementing Transitioning Together at 30 public high schools across three US states that were participating in the intervention arm of a larger randomized trial, which provided training and coaching for implementation of comprehensive evidence-based autism programming. Seventeen of the 30 schools adopted Transitioning Together. Community socioeconomic status and pre-existing quality of programming for family involvement and transition planning significantly predicted intervention adoption. Thirteen of the 17 schools that adopted Transitioning Together did so with a high level of fidelity (>90%). The areas of fidelity that schools struggled with most related to session structure, facilitating problem-solving and dialogue, and collecting feedback from families. Findings highlight struggles and successes with real-world adoption of the intervention in its current form. Future research is needed to further examine how to facilitate adoption across public high schools and/or other service systems, while maximizing effectiveness, as well as reach to historically underserved autism spectrum populations. Lay Transitioning Together is an intervention that supports families of adolescents on the autism spectrum as they prepare for the transition to adulthood. While it has been delivered successfully and shown to result in positive outcomes for families in the university setting, questions remain about whether and how well it can be widely provided to families in real-world settings such as high schools. In this study, we analyzed predictors, facilitators, and barriers to providing Transitioning Together to families at 30 high schools across three US states, all of which received training from a team of researchers to deliver this intervention. Our findings highlight struggles and successes with real-world use of the intervention. Seventeen of the 30 schools were successful in providing Transitioning Together to families. Schools who had higher community socioeconomic status, higher quality family involvement, and higher quality transition planning programming before changing anything for this study were much more likely to provide this new intervention to families. Schools who used the intervention were mostly able to deliver it as designed and received positive feedback from families who participated. Common parts of the intervention that schools struggled with most included following the structure of the sessions, including group problem-solving and dialogue in the sessions, and collecting feedback from families. Future research is needed to learn how to make it even easier for public high schools and other service systems to provide this intervention to families, in a way that also maximizes its effectiveness and accessibility for historically underserved autism spectrum populations.
