There is robust evidence that racism negatively influences health outcomes for African American college students. However, few studies have longitudinally examined the underlying mechanisms related to the repercussions of racism.
Objective
The purpose of this study was to examine the longitudinal association between racial discrimination and psychological well‐being (PWB), as well as the mediating role of distress intolerance.
Method
As part of a larger parent study, a sample of 105 African American first‐year undergraduate students (mean age = 18.1) completed three surveys across 1 year. The RMediation program was used to test the indirect effect of racism on PWB through distress intolerance.
Results
There was a significant positive indirect effect of racism on PWB through distress intolerance, such that increased racism was associated with increased distress intolerance, which was thus associated with decreased PWB.
Conclusions
Intervention efforts may be aimed at preventing racism for African American college students and providing clinical services that reduce distress intolerance.
There is robust evidence that gendered racial microaggressions affect Black women's mental health. However, few studies have examined how this form of discrimination affects Black women's social anxiety in addition to their general anxiety, as well as the underlying mechanisms related to gendered racial microaggressions and anxiety.
Objective
The purpose of this study was to examine the associations between gendered racial microaggressions stress (GRMS) and gendered racial microaggressions frequency (GRMF), and Black women's social anxiety and general anxiety symptoms. We also examined the mediating roles of distress intolerance and stress in these associations.
Method
One hundred and sixty‐three Black women, between the ages of 18 and 25 years old, completed a cross‐sectional survey. Regression analyses were used to examine the associations between gendered racial microaggressions and social anxiety and general anxiety, and mediation analyses examined the indirect effect of gendered racial microaggressions on the outcome variables through distress intolerance and stress.
Results
GRMS was associated with greater social and general anxiety through the mechanisms of distress intolerance and stress. GRMF was associated with reduced social anxiety and was not associated with general anxiety.
Conclusions
Intervention efforts should be aimed to prevent the experience of gendered racial microaggressions to prevent subsequent stress and mental health outcomes for Black women.
Walleye Sander vitreus is one of the most important freshwater commercial and sport fishes in western Canada. It is an intensively managed species that is under considerable harvest pressure, yet little is known about the patterns of genetic variation and diversity of walleyes between connected water bodies and among river basins in this region. We examined the genetic variation of walleyes from 12 lakes in five different river basins of northern Alberta. Each lake contained a genetically distinct walleye subpopulation nested within a larger population of the river basin in which the lake was situated. Differentiation between subpopulations varied (FST = 0.05–0.29) and exhibited a broad‐scale isolation‐by‐distance pattern. Patterns of genetic divergence aligned closely with the current hydrogeographical landscape, as subpopulations in the same river basin were more similar than those in different river basins. The clear and distinct pattern of genetic structure is likely to have been generated and maintained by historical vicariance and natal philopatry. Because walleye populations are so clearly genetically structured by hydrogeography in western Canada, these data can be used to monitor population status, assess stocking programs, delineate management units, and enable forensic enforcement of harvest restrictions in this region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
