Abstract
The purpose of the present investigation was to develop and test a measure of negative emotional reactivity to racial/ethnic minoritized stress. In Study 1, we developed item content for a measure of negative emotional reactivity to racial/ethnic minoritized stress. We then evaluated item performance and produced a refined 15-item scale among a large sample of racial/ethnic minority adults (N = 1,343). Results supported a unidimensional construct and high levels of internal consistency. The factor structure and internal consistency were replicated and extended to a sample of Latinx persons who smoke (N = 338) in Study 2. There was evidence of convergent validity of the Emotional Reactivity to Minoritized Stress (ERMS) total score in terms of theoretically consistent and statistically significant relations with indices of mental health problems, social determinants of health, and substance use processes. There was also evidence that the ERMS demonstrated divergent validity in that it was negatively associated with psychological well-being, health literacy, subjective social status in Study 1, and positive abstinence expectancies in Study 2. Overall, the present study establishes the reliability and validity of measuring individual differences in negative emotional reactivity to racial/ethnic minority stress with the ERMS and that such responsivity is associated with behavioral health problems.
