Abstract
Autistic adults face considerable challenges in receiving adequate support, from both paid/formal (such as from disability services) and unpaid/informal (for example, from friends and family) sources. Having adequate support can lead to better health and well-being outcomes. However, most instruments designed to assess adequacy of support were not made specifically for/with autistic adults. This paper presents a psychometric validation of the AASPIRE Adequacy of Supports and Information Scale (AASIS), a community-informed adaptation of a previously developed instrument (the Quality of Care and Support scale; Lucas-Carrasco et al., 2011), designed to be relevant and accessible to autistic adults. We also used the AASIS to explore correlates of perceptions of support in a sample of 798 autistic adults. Our confirmatory factor analysis supported a two factor structure for the AASIS (factor one: Supports; factor two: Information). Further testing confirmed the instrument was invariant across several groups, including race/ethnicity, gender, intellectual disability, communication fluency, and self versus proxy-report. Regression analyses suggested that the way in which participants joined the study (i.e., through community advertisements or via established healthcare/disability services) impacted whether they viewed their support as adequate. Additionally, a higher number of adverse childhood events and greater experience of discrimination were related to worse perceptions of support adequacy across both factors. Our findings support the preliminary validity of the AASIS across a variety of autistic people, though further testing is warranted. Findings also point to the importance of addressing the needs of autistic people who are minoritized and/or who have complex trauma histories.
