Abstract and Keywords

This chapter presents key findings from behavioral genetic studies of the externalizing spectrum, with particular emphasis on quantitative genetic research on genetic and environmental factors using twin and adoption studies. It first provides a historical overview of behavioral genetic studies of externalizing problem behaviors before turning to a discussion of the primary research designs—twin and adoption studies—and their methodological designs and drawbacks. It then reviews evidence for genetic and environmental influences on individual disorders within the externalizing spectrum, namely, attention-deficit/hyperactivity disorder, oppositional defiant disorder, conduct disorder, antisocial personality disorder, and substance use disorders, along with their comorbidities. It also considers twin and adoption studies of antisocial behavior such as aggression, criminality, and delinquency, as well as traits that characterize psychopathy. The chapter concludes with a discussion of the current state of the science and suggests directions for future research on the behavioral genetics of the externalizing spectrum.

Keywords: behavioral genetic studies, externalizing spectrum, twin and adoption studies, attention-deficit/hyperactivity disorder, oppositional defiant disorder, conduct disorder, antisocial personality disorder, substance use disorders, antisocial behavior, behavi
