Associations of neighborhood deprivation and household income during pregnancy on child externalizing and internalizing problems

Socioeconomic disadvantage has been established as a key risk factor for adverse child behavioral outcomes. Understanding how individual components of socioeconomic status (SES) interact with each other can elucidate protective factors and inform interventions and policies to promote positive developmental outcomes. This study examined the interactive effects of prenatal household income and neighborhood deprivation on child externalizing and internalizing problems (<i>N</i> = 793; <i>M</i>_age = 8.37 years; 51.2% females; 81.5% White). Results revealed an interaction effect between prenatal household income levels and neighborhood deprivation on child externalizing problems. Higher neighborhood deprivation was associated with higher child externalizing outcomes only at lower household income levels per person. Although no interaction between household income and neighborhood deprivation on child internalizing problems was observed, lower household income levels were independently associated with higher child internalizing problems. These findings underscore how prenatal individual- and neighborhood-level SES factors interact to shape children's behavioral outcomes across childhood.
