United and Divided by Stress: How Stressors Differentially Influence Social Support in African American Couples Over Time.

The factors that allow people to be good support providers in relationships are not fully understood. We examined how support providers' stressful experiences (financial strain and racial discrimination) differentially influence their supportiveness, using longitudinal data from two samples of African American couples. Among couples that provided observational data ( N = 163 couples), providers who experienced high chronic financial strain behaved less supportively toward their partners, while those who experienced frequent racial discrimination behaved more supportively over a 2-year period. In a second sample of 213 couples over a 3-year period, support providers who experienced financial strain were perceived by their partners as slightly less supportive, while providers who experienced frequent racial discrimination were perceived by their partners as more supportive. Findings suggest that supportiveness in relationships may be differentially shaped by the specific stresses and strains that partners face.
