<p>There is a large body of research measuring and examining the impact of how racism-related vigilance, or worries about facing racism in future, is related to health, but there has been very little assessment of worries or vigilance parents may have about their children facing racism and discrimination. To fill this gap, the present study evaluated the psychometric properties of the 22-item Worries About Racial Profiling scale (WARP; in: Stevenson &amp; Winn, Development of the Worrying about Racial Profiling Scale (WARP). REC Report #0003, Racial Empowerment Collaborative, Human Development and Quantitative Methods Division, Graduate School of Education, University of Pennsylvania, Philadelphia, PA, 2016), an increasingly used and sole measure of parental worries about their children facing racism for which no previous psychometric analyses have been conducted. Participants were 391 Black (<i>n</i> = 203) and Latine (<i>n</i> = 188) American parents (<i>M</i>_age = 43.39,&#xa0;<i>SD</i> = 9.52, 60.90% mothers) with a child between 10 and 18. A bifactor exploratory structural equation model provided the best fit to the data, indicating that 97.3% of the variation in the 22 WARP items was accounted for by a general worries factor, while two specific factors captured a trivial amount of variability. Ancillary fit indices indicated that the WARP general factor was so strong that the measure should be treated as unidimensional. The WARP was invariant across multiple aspects of identity. Greater parental worries were positively associated with participants’ racism exposure, parents’ depressive symptoms, and children’s internalizing symptoms. Overall, the WARP demonstrated strong psychometric properties and may be used to examine the psychological and behavioral causes, correlates, and consequences of parents’ worries about their children of color facing racism and discrimination.</p>
