9SCALE Overview
Developed as part of the broader Intersectional Discrimination Index (InDI), the InDI-D is an attribution-free measure grounded in intersectional frameworks and stigma theory that does not require respondents to ascribe incidents to any specific social identity category. Each item assesses perceived unfair treatment “because of who you are” on a four-point frequency scale (response options ranging from “never” to “yes, many times in the past year”), capturing both lifetime occurrence and recent frequency of day-to-day discrimination.
Initial validation studies support the InDI-D as a unidimensional scale with robust psychometric properties, and individuals with intersecting marginalized identities (e.g., racial/ethnic minorities, LGBTQ+ people, immigrants, or people experiencing homelessness) report higher InDI-D scores, demonstrating its sensitivity to intersectional stigma. As an integral component of the InDI, the day-to-day discrimination scale can be applied across diverse settings – including healthcare, employment, housing, education, and law enforcement – to assess the prevalence and impact of routine discrimination and to inform interventions addressing social inequities in populations with overlapping marginalized identities.
