Abstract Although temperamental negative affectivity has been identified as a developmental mechanism mediating the link between perinatal risk and internalizing problems in early childhood, its role in predicting broader behavioral and emotional problems across childhood remains understudied. We examined the longitudinal relations among perinatal complications (i.e., prenatal maternal depression and cardiometabolic complications, preterm birth, and low birth weight), children’s negative affectivity ( M age = 2.76; SD = 2.32; range = 0.24–12.46 years), and children’s internalizing, externalizing, and total problems ( M age = 5.12; SD = 2.63; range = 1.50–16.85 years) in the Environmental influences on Child Health Outcomes (ECHO) program ( N = 3070; 47% females). Results support child negative affectivity as a mechanism in the developmental pathway linking perinatal maternal depressive symptoms and preterm birth to future emotional and behavioral problems, underscoring the importance of early prevention and intervention efforts to promote psychological well-being of at-risk children.
