The Socioeconomic Pathways Leading to Romantic Relationship Outcomes: A Genetically Informed Early Life Course Investigation.

The present study tests a multilevel comprehensive model incorporating both life course processes and genetic influences leading to young adults' romantic relationship quality using data from 1,560 adolescents over 13 years in the nationally representative Add Health sample. Results provided evidence of a socioeconomic mediating pathway linking early family and community contexts to young adults' romantic relationship quality, and novel evidence for both direct and interactive genetic associations that relate to these mediating pathways. A cumulative genetic index showed (a) direct associations with young adults' socioeconomic attainment and (b) interactions with community adversity and mothers' marital stability on young adults' achieved socioeconomic context and relationship quality.
