Two studies examine common and pattern-specific antecedents and consequences of these types of deviancy, by exploring the role of mothers and fathers in intergenerational behavioral transmission related to smoking and delinquency and analyzing shared and unshared risk factors among persons who use drugs, commit theft and vandalism, and are violent. Papers in the section on reciprocal influences among drug use, crime, and other forms of deviance examine the effects of long-term social-psychological influences, and the relationship between alcohol use and crime. Intervening variables in causal relationships among deviant behaviors may include personality and social control, and family relationships and school performance. Several studies explore possible moderators of the relationship between drug use, crime, and other forms of deviant behavior, such as self-attitudes and antisocial personality, and ethnic or cultural background. The final section discusses emerging issues in longitudinal research on deviant behavior. Chapter references
