The intersecting disability and race attitudes implicit association test.

Purpose: Due to the ways disability and race overlap, intersect, and inform each other, to dismantle ableism, we must first understand how these processes operate in an intersectional manner, including when it comes to implicit bias. Yet, social psychology, and its prominent measures, including the implicit association test (IAT), have often taken a single-axis approach rather than attending to intersectionality. This study's aim was to develop and establish the intersecting disability and race attitudes implicit association test (IDRA-IAT).

Research method: We piloted the IDRA-IAT (July-October 2024) with 536 people (27.7% nondisabled White people, 32.3% disabled White people, 12.7% nondisabled people of color, and 27.3% disabled people of color). We analyzed the data using descriptive statistics, t tests, split-half reliability (internal consistency), and correlation analyses (test-retest reliability, and construct validity).

Results: People preferred nondisabled White people the most (M = 0.19), then disabled White people (M = 0.04), then nondisabled people of color (M = -0.09), and then disabled people of color (M = -0.13). However, the findings differed significantly based on the participants' identities. Our findings also indicated the IDRA-IAT has similar psychometrics to other IATs.

Conclusion: To advance disability justice, much more research about intersectionality and quantitative methodologies that promote intersectionality are necessary. We recognize that there is a lot more that comprises oppression and discrimination than attitudes alone. However, our hope is that the IDRA-IAT can be one valuable tool in the arsenal of many in the work to dismantle the oppression disabled people face.
