Research casts interracial romantic partners (IRPs) as deficient in their relational functioning compared to same-race partners due to the potential for increased relational conflict and stress. More relational stressors are likely to result in a higher need for social support from network members. Yet, interracial partners can maintain satisfying, thriving relationships and experience few racially motivated stressors, rendering support unnecessary at times. The dissertation explores the social resources IRPs use to maintain their interracial romantic relationships (IRRs) by examining processes of social support and strain among Black-White IRPs and their family members. In these processes, the researcher focuses specifically on support expectations, which are anticipations of the support individuals are likely to receive from particular others. The researcher conducted in-depth interviews with 32 IRPs and 30 parents of IRPs to understand support as a cohesive, long-term process involving participants’ support expectations and their violations, which could result in experiences of support and/or strain. A grounded theory analysis of the interview data resulted in an inductive model of expectations for social support and strain. Three constructs influenced expectations for IRR involvement and support, including exposure to racial diversity, assessments of racial identifications, and cultural comparisons. Based on these expectations, participants came across three support paths after initiating support-seeking disclosure strategies. Their expectations for familial support were met, they received more support than they anticipated, and/or they received less support than expected. Encounters with these support paths resulted in support and strain for IRPs and their parents, however interracial partnerships largely experienced resilience whereas hardships befell familial ties. Taken together, the results contribute to theorizing about processes of support and their functionality in underrepresented romantic relationship forms.
