Neighborhood Stress and Mental Health: The Protective Role of Couple Relationship Functioning in Rural African American Communities
Community stressors do not remain confined to the neighborhood but rather spill over into individuals’ and couples’ lives. Economic hardship, limited healthcare access, environmental hazards, and safety concerns can shape key aspects of daily functioning, including mood, sleep, and interpersonal processes. For couples living in structurally disadvantaged rural contexts, these chronic stress exposures may increase risk for depressive symptoms. At the same time, strong romantic partnerships may function as protective relational systems, buffering the psychological impact of sustained environmental strain.
In the MRI-funded project Neighborhood Stress and Mental Health: The Protective Role of Couple Relationship Functioning in Rural African American Communities, Principal Investigator Dr. Man-Kit Lei (University of Georgia), Co-Investigator Dr. Steven Beach (University of Georgia), and doctoral student Rachael Weaver (University of Georgia) examine whether high-quality couple functioning mitigates depression risk under chronic neighborhood stress. Grounded in ecological systems theory and relationship science, the study centers rural, low-income African American couples in the Southern United States—communities often underrepresented in multilevel mental health research despite facing pronounced structural inequities that increase mental health risk and present barriers to care.
The project uses data from 346 middle-aged African American couples who previously participated in the Protecting Strong African American Families (ProSAAF) randomized trial. Using geocoded residential addresses, the research team connects participants to neighborhood-level indicators derived from geospatial datasets, including concentrated socioeconomic disadvantage, housing strain, healthcare access, environmental pollutants, and residential segregation. This multilevel design allows examination of how objective community conditions relate to depressive symptoms over time.
A primary analytic goal is to test whether indices of couple functioning—such as relationship confidence, communication quality, satisfaction, and perceived partner support—moderate associations between neighborhood stress and mental health outcomes. By modeling cross-level interactions, the study evaluates whether supportive relational processes buffer individuals from the psychological effects of structural disadvantage.
Beyond documenting structural risk, the project seeks to clarify mechanisms of resilience. If couple functioning attenuates depression risk in high-stress environments, relationship-focused interventions may serve as culturally responsive strategies for reducing mental health disparities in rural communities in which broader structural conditions like neighborhood stress cannot be quickly alleviated. Findings may inform adaptations of couple-based programs that explicitly account for neighborhood context and structural stressors.
By integrating geospatial data with dyadic relationship measures, this research advances a contextually grounded model of mental health. It underscores that resilience is not solely an individual trait but can emerge within intimate partnerships that provide stability and support amid chronic environmental stress.
