Genetic and environmental influences underlying the relationship between low self-control and substance use

AbstractPurpose rrent study seeks to examine the relationship between low self-control and cigarette smoking, alcohol use, and marijuana use in adolescence and adulthood using behavioral genetic methodology. s a subsample of twin pairs from the National Longitudinal Study of Adolescent Health (Add Health), the current study estimates the genetic and environmental overlap between low self-control and substance use (or problems associated with substance use) across four waves of data collection. s erall pattern of results suggests that genetic factors explain a moderate proportion of the variance in low self-control and substance use in both adolescence and adulthood. Furthermore, bivariate genetic analyses reveal that the correlation between low self-control and substance use is due, for the most part, to common genetic and nonshared environmental factors. sions rrent study adds to a growing body of biosocial research on self-control and its relationship to criminal and analogous behaviors. The implications of our findings for the general theory of crime are discussed.
