In the EA sample, parental EXT PGS was corelated with their own externalizing behavior, adolescent externalizing behavior, and parent-child closeness, but not with other aspects of parenting. Adolescent EXT PGS was correlated with their own externalizing behavior, and negatively correlated with all aspects of parenting except parental involvement (i.e., higher externalizing genetic risk was associated with less parent-child communication, closeness, and knowledge). Parental externalizing behavior was correlated with lower parent-child closeness and lower parental knowledge. Adolescent externalizing behavior was correlated negatively with all parenting measures.
