Development and validation of the Ethnic-Racial Discrimination Stress Inventory (ERDSI) for Mexican-origin U.S. adults and Turkish-origin German adults.

Objectives: We developed the 26-item Ethnic-Racial Discrimination Stress Inventory (ERDSI) to assess ethnic-racial discrimination stress in Mexican-origin adults in the United States and Turkish-origin adults in Germany, two groups with similar sociocultural characteristics and immigration experiences.

Method: We developed 73 items measuring firsthand, intragroup, and vicarious discrimination, and internalization and expectations of discrimination experiences. If participants reported experiencing a given situation, they were asked to rate its stressfulness. U.S.-based Mexican-origin adults (N = 222) and German-based Turkish-origin adults (N = 105) completed an online survey of these items, measures of related constructs, and sociodemographic measures.

Results: Study 1: We eliminated items based on interitem correlations and exploratory factor analyses in the U.S.-based Mexican sample. The exploratory factor analyses yielded four reliable and valid factors (F1: Vicarious Discrimination Stress, seven items; F2: Internalization of Discrimination Stress, seven items; F3: Intragroup Discrimination Stress, seven items; and F4: Firsthand Discrimination Stress, five items). The ERDSI factors predicted well-being measures, even after adjusting for control variables. Study 2: The three ERDSI factors (F1, F2, F4, not F3) that applied to the German-based Turkish sample demonstrated reliability and validity. Confirmatory factor analyses demonstrated metric invariance for F2 and partial scalar invariance for F1, F3, and F4.

Conclusions: The ERDSI can be used to assess ethnic-racial discrimination stress in future studies with U.S.-based Mexican-origin adults and German-based Turkish-origin adults. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
