To date, most research has focused on the relations of these traits to risky behaviors. The logic is that if these traits dispose individuals to rash or ill-considered actions, individual differences in the traits should be associated with, and predict, individual differences in engagement in behaviors associated with risk of harm. Consistent with the separation of the traits structurally, research has shown not only that the five traits do correlate with and predict risky behavior, but that they relate to different aspects of risky behavior (Anestis, Selby, Fink, & Joiner, 2007a; Anestis, Selby, & Joiner, 2007b; Billieux, Rochat, Rebetz, & Van der Linden, 2008; Billieux, Van der Linden, & Ceschi, 2007a; Billieux, Van der Linden, D'Acremont, Ceschi, & Zermatten, 2007b; Cyders et al., 2007a; Cyders, Flory, Rainer, & Smith, 2007b; Cyders & Smith, 2007, in press; Fischer, Anderson, & Smith, 2004; Fischer & Smith, 2004; Fischer & Smith, in press; Fischer, Smith, & Anderson, 2003; Fischer, Smith, Annus, & Hendricks, 2007; Miller, Flory, Lynam, & Leukefeld, 2003; Smith et al., 2007a; Verdejo-Garcia, Bechara, Recknor, & Perez-Garcia, 2007; Whiteside & Lynam, 2003; Whiteside et al., 2005).
