Young adults (Mage = 20.14, SD = 3.94), including 473 full-sibling pairs and 209 half-sibling pairs (N = 1,364) from the Child and Young Adult Sample of the National Longitudinal Survey of Youth were analyzed to examine the association between violent victimization and depression from late adolescence to young adulthood, estimate how much additive genetic and environmental factors account for variation in liability for single and repeat violent victimization and major depression, and compare the magnitude of genetic and environmental influences on the covariance in liability between single and repeated victimization and major depression. Cross–lagged models revealed that while victimization was associated with an increased risk for depression during late adolescence, major depression was more strongly and consistently associated with increased risk for future victimization across young adulthood. Biometric models revealed that 20% of the association between single victimization and major depression was accounted for by common additive genetic influences, while 30% of the association between repeat victimization and major depression was accounted for by common additive genetic influences. Results and implications are discussed. ER -
