Almost 50% of single-mother households live below 200% of the poverty line. In addition to material needs, mothers living in poverty have higher levels of psychological distress. Although some forms of network support (e.g., perceived support, welcomed support) promote well-being, how do financial transfers relate to unmarried mothers’ levels of distress? Drawing from support mobilization, social inequity, and reciprocity theories, this study used The Fragile Families and Child Wellbeing Study (FFCWS) ( n = 3,117 mothers and 10,676 observations) and longitudinal mixed-effects models to examine financial transfer behavior stability and its relationship to maternal psychological distress. Results indicate that, net of extensive controls, mothers commonly participated in giving or receiving money despite their disadvantaged, volatile circumstances, and engagement, regardless of direction, related to more symptoms of distress. This connection is problematic given the weakening public cash safety net and U.S. economic uncertainty.
