Abstract
Racially and ethnically minoritized (minoritized) autistic individuals face intersectional disparities in service access in the transition to adulthood. Our understanding of disparities is limited by systematic exclusion from research and inadequate approaches to characterizing services. To address these gaps and effect advocacy, this study (1) examined services received, unmet service needs, and barriers in minoritized autistic adolescents and adults and (2) determined if language, NVIQ, and autism traits predict services when deployed as binary or continuous variables. Academic and community partners tailored community-based participatory research (CBPR) to a local context. Participants (N = 73, ages 13-30) completed a behavioral assessment protocol. Participants and caregivers provided information on services received, unmet service needs, and barriers to services. Data were analyzed using descriptive and regression. Participants received multiple services yet had multiple unmet service needs and barriers. Effects of services differed by approach. Language impairment, but not language scores, predicted receiving more services. High levels of autism traits and autism trait scores predicted more unmet service needs. While the number of services and unmet service needs was similar to prior work, differences in individual service variables and effects support attention to heterogeneity. Findings support intersectional approaches to CBPR and autism research.
