Background Numerous studies have shown that racial/ethnic minority and under-resourced families face barriers that delay timely access to autism services. These barriers include lack of resources and information about autism, financial hardship, mistrust in the service system, cultural and language mismatch, and other factors that have yet to be identified. Method The current study aimed to examine additional caregiver and system-level factors that could be associated with early service access using a diverse sample from four study sites (Los Angeles, CA; Philadelphia, PA; Sacramento, CA; and Rochester, NY). Partnering with community agencies that serve traditionally underrepresented groups, the research team recruited 118 caregivers of young children with autism who were low-income, English, Spanish or Korean speaking and had not accessed autism-specific services. Results Regression analyses revealed that the total number of services accessed were associated with caregiver social network size (p = 0.011) but not by race, autism knowledge and caregiver agency. Among families receiving at least one non-autism specific service, a marginally significant interaction effect of site and primary language on total services received was observed (p = 0.06). Conclusion Findings suggest that caregivers’ social network connections are crucial in early service access, and future interventions could target increasing social networks to improve families’ service engagement. More attention for non-English speaking families, especially those living in areas with few supports in their native languages, is needed.

Objective To illustrate the process of community-partnered participatory research to develop and evaluate interventions for children with autism in urban school districts. Methods We formed partnerships of school personnel, parents, and researchers to guide the project. We then conducted focus groups, key informant interviews, and town halls to explore how public schools currently serve students with autism. We used findings from these activities to adapt interventions for public schools. We then tested interventions in randomized clinical trials (RCTs). Results Community input indicated a particular need for interventions to improve children's social interaction and instructional supports to promote their success throughout the day. On the basis of this input, we adapted 2 interventions: Remaking Recess for improving peer engagement during social times; and Schedules, Tools, and Activities for Transition (STAT) for facilitating successful transitions between activities throughout the daily routine. Results of the RCT of Remaking Recess are not yet available. The RCT of STAT involved 150 children and 56 teachers. Teachers reported high buy-in and increased their proficiency at implementing STAT; children with ASD reduced their disruptive behavior and made progress toward teacher-nominated goals. However, teachers' implementation remained inconsistent, and children did not reliably improve in academic engagement or independence. Conclusions The findings suggest that although community-partnered participatory research has limitations, it can assist in selecting interventions to address community priorities and produce some favorable outcomes for children with autism in public schools. An important next step is to evaluate the sustainability of the interventions introduced in this project.
