Members of the ATR born between 1964-1971 were contacted again between 2004-2007 (or an average of eight years after the 1996-2000 interview) to participate in another structured telephone interview in which adult antisocial behavior (AAB) was assessed. The participation rate for this 2004-2007 interview was 80.4% (Slutske et al., 2009). There was some evidence that individuals with a history of conduct disorder were less likely to participate in this interview than those without such a history, though the net effect of this differential attrition was small (see Slutske et al., 2009 for details). A total of N=4,764 individuals participated in the 2004-2007 interview. Of the 4,764 twins who participated in this interview, 17 twins were excluded from the current analyses due to missing data. At the time of this 2004-2007 interview, the twins were between 32-43 years of age (M=37.66, SD=2.30).
