Data for testing these predictions came from the Minnesota Longitudinal Study of Risk and Adaptation (MLSRA; Sroufe et al., 2005), which has followed approximately 165 first-born children from birth through adulthood. Participants’ mothers were originally recruited into the study during the third trimester of pregnancy while they were receiving prenatal care at Minneapolis public health clinics. The analyses in this study are based on a subset of the sample (n = 93, 53% female, 47% male) for whom young adult romantic relationship quality was assessed at age 23. Sixty-eight percent of these participants were White, 22% were of mixed, other, or unknown race, and 10% were Black.1
