The relation between perceived racial discrimination and substance use was examined in two studies that were based on the prototype – willingness model (Gibbons, Gerrard & Lane, 2003). Study 1, using structural equation modeling, revealed prospective relations between discrimination and use five years later in a panel of African American adolescents (M age 10.5 at T1) and their parents. For both groups, the relation was mediated by anger/hostility. For the adolescents, it was also mediated by behavioral willingness, and it was moderated by supportive parenting. Study 2 was a lab experiment in which a subset of the Study 1 adolescents (M age = 18.5) was asked to imagine a discriminatory experience, and then their affect and drug willingness were assessed. As in the survey study, discrimination was associated with more drug willingness and that relation was again mediated by anger and moderated by supportive parenting. Implications of the results for research and interventions involving reactions to racial discrimination are discussed.

Perceived racial discrimination, self-control, anger, and either substance use or use cognitions were assessed in two studies conducted with samples of African American adolescents. The primary goal was to examine the relation between discrimination and self-control over time; a second goal was to determine if that relation mediates the link between discrimination and substance use found in previous research. Study 1, which included a latent growth curve analysis with three waves of data, indicated that experience with discrimination (from age 10 to age 18) was associated with reduced self-control, which then predicted increased substance use. Additional analyses indicated anger was also a mediator of this discrimination to use relation. Study 2, which was experimental, showed that envisioning an experience involving discrimination was associated with an increase in substance-related responses to double entendre words (e.g., “pot,” “roach”) in a word association task, especially for participants who were low in dispositional self-control. The effect was again mediated by reports of anger. Thus, the “double mediation” pattern was: discrimination → more anger and reduced self-control → increased substance use and/or substance cognitions. Results are discussed in terms of the long-term impact of discrimination on self-control and health behavior. Implications for interventions aimed at ameliorating the negative effects of discrimination and low self-control on health are also discussed.

Three studies tested the hypothesis that the relation between perceived racial discrimination and substance use reported in previous research is moderated by use of substances as a coping mechanism. Studies 1 and 2 were experimental studies of African American adolescents’ and young adults’ reactions to a discrimination experience. Results revealed that those who endorsed substance use-as-coping reported more willingness to use substances after experiencing discrimination. Study 3 was a prospective study of the relation between perceived discrimination and substance use over an 8-year period in African American adolescents. Results demonstrated that discrimination is associated with increases in substance use, but only among adolescents who endorse substance use-as-coping. Together, these three studies provide evidence that experiencing discrimination has both short- and long-term detrimental effects on African Americans’ substance use, but significantly more so for those who adopt a pattern of using substances as a coping mechanism.

The impact of three different sources of stress—environmental, familial (e.g., low parental investment), and interpersonal (i.e., racial discrimination)—on the life history strategies (LHS) and associated cognitions of African American adolescents were examined over an 11-year period (five waves, from age 10.5 to 21.5). Analyses indicated that each one of the sources of stress was associated with faster LHS cognitions (e.g., tolerance of deviance, willingness to engage in risky sex), which, in turn, predicted faster LHS behaviors (e.g., frequent sexual behavior). LHS then negatively predicted outcome (resilience) at age 21.5; i.e., faster LHS → less resilience. In addition, presence of the risk (“sensitivity”) alleles of two monoamine-regulating genes, the serotonin transporter gene (5HTTLPR) and the dopamine D4 receptor gene (DRD4) moderated the impact of perceived racial discrimination on LHS cognitions: Participants with more risk alleles (higher “sensitivity”) reported: faster LHS cognitions at age 18 and less resilience at age 21, if they had experienced higher amounts of discrimination ; and slower LHS and more resilience if they had experienced smaller amounts of discrimination. Implications for LHS theories are discussed.

This study investigated how early experience with racial discrimination affected the subsequent risky sexual behaviors of a diverse sample of African American youths (N = 745). The analyses focused on 3 risk-promoting factors thought to mediate the hypothesized discrimination → risky sex relation: negative affect, affiliation with deviant peers, and favorable attitudes toward risky sex. In addition, attentive parenting was examined as a protective factor. Analyses using structural equation modeling revealed that youths who perceived more racial discrimination at age 10 or 11 were engaging in more sexual risk taking at age 18 or 19. This relation was mediated by the hypothesized risk-promoting factors via pathways that were consistent with our conceptual model. Results also indicated a prospective reciprocal relation between parenting and children’s deviant affiliations: deviant peer affiliations at age 10 or 11 predicted more attentive parenting behaviors by the parents; this response from the parents, in turn, predicted relatively fewer deviant affiliations when the youths were 15 or 16. Study findings are discussed in terms of their relevance to the disproportionately high rates of sexually transmitted infections among African Americans.

Objective Prospective data tested a “differential mediation” hypothesis: The relations (found in previous research) between perceived racial discrimination and physical health status versus health-impairing behavior (problematic substance use) are mediated by two different types of affective reactions, internalizing and externalizing. Methods The sample included 680 African American women from the Family and Community Health Study (M age = 37 at Time 1; 45 at Time 4). Four waves of data were analyzed. Perceived discrimination was assessed, along with anxiety and depression (internalizing) and hostility / anger (externalizing) as mediators, and physical health status and problematic substance use (drinking) as outcomes. Results Structural equation modeling indicated that discrimination predicted increases in both externalizing and internalizing reactions. These affective responses, in turn, predicted subsequent problematic substance use and physical health status, respectively, also controlling for earlier reports. In each case, the indirect effects from discrimination through the affective mediator to the specific health outcome were significant and consistent with the differential mediation hypothesis. Conclusion Perceived racial discrimination is associated with increases in internalizing and externalizing reactions among Black women, but these reactions are related to different health outcomes. Changes in internalizing are associated with self-reported changes in physical health status, whereas changes in externalizing are associated with changes in substance use problems. Discussion focuses on the processes whereby discrimination affects health behavior and physical health status.

Perceived discrimination is a risk factor for mental health problems among sexual minority individuals. An increasing number of research studies have investigated the mechanisms through which stigma-related stressors such as perceived discrimination are linked with adverse mental health outcomes for sexual minority populations. The integrative mediation framework proposed by Hatzenbuehler (2009) underscores the importance of identifying mediators in the association between stigma-related stressors and mental health outcomes. This study tested 3 mediators--expectations of rejection, anger rumination, and self-compassion--in the perceived discrimination-distress link. Moreover, it examined associations among these mediators. A nationwide sample of 265 sexual minorities responded to an online survey. Structural equation modeling results supported the mediator roles of expectations of rejection, anger rumination, and self-compassion. More specifically, perceived discrimination was associated with expectations of rejection, which, in turn, was associated with increased anger rumination and less self-compassion, resulting in greater psychological distress. The findings suggest several avenues for prevention and intervention with sexual minority individuals.

This study examined whether living up to parental expectations and internalized stereotyping (i.e., internalizing Asian American stereotypes) mediated the impact of parental pressure and support on occupational outcomes (i.e., self-efficacy, outcome expectations, and interests in stereotypical occupations) among 229 Asian American students from universities nationwide. Results indicated that living up to parental expectations and internalized stereotyping partially mediated the associations between parental pressure and these 3 occupational outcomes. In addition, living up to parental expectations fully mediated the associations between parental support and the 3 occupational outcomes, but internalized stereotyping did not. The results demonstrated the differential role of parental pressure and parental support as well as the mediating role of living up to parental expectations and internalized stereotyping in Asian Americans' occupational outcomes. Future research directions and clinical implications are discussed.
