How does stigma "get under the skin"?: the mediating role of emotion regulation.

Stigma is a risk factor for mental health problems, but few studies have considered how stigma leads to psychological distress. The present research examined whether specific emotion-regulation strategies account for the stigma-distress association. In an experience-sampling study, rumination and suppression occurred more on days when stigma-related stressors were reported than on days when these stressors were not reported, and rumination mediated the relationship between stigma-related stress and psychological distress. The effect of social support on distress was moderated by the concealability of the stigma: Lesbian, gay, and bisexual (LGB) respondents reported more isolation and less social support than African American respondents subsequent to experiencing stigma-related stressors, whereas African Americans reported greater social support than LGB participants. Social isolation mediated the stigma-distress association among LGB respondents. In a second experimental study, participants who ruminated following the recall of an autobiographical discrimination event exhibited prolonged distress on both implicit and explicit measures relative to participants who distracted themselves; this finding provides support for a causal role of rumination in the stigma-distress relationship.
