Finding the Right Angle: A Geometric Approach to Measuring Intersectional HIV Stigma.

Intersectionality has emerged as theoretically and practically important to advancing HIV stigma research. However, few psychometric measures capture the intricacies of intersectional stigma. Grounded in the HIV stigma framework and contemporary theories of intersectionality, this paper describes a novel approach to conceptualizing the measurement of intersectional stigma. Taking the notion of an intersection literally, that is the point at which two or more lines meet and form a union, we offer a geometric conceptualization for developing a psychometric instrument to measure intersectional stigma. Ratings of stigmatized attributes, such as stigma ascribed to gender, race, sexual orientation, and HIV status are assessed on independent scales to calculate their intersection using the Pythagorean Theorem, c = [Formula: see text] (a2 + b2) and its extension to multiple stigmatized attributes d = [Formula: see text] (a2 + b2 + c2). Data from a sample of Black /African American women living with HIV were used to test the concept of a geometric approach to measuring intersectional enacted stigma and intersectional anticipated stigma. Findings from the test of concept were encouraging and warrant further scale development research.
