Efforts to disaggregate the set of constructs included within the impulsivity framework have proven quite useful. One current model involves identification of five separate constructs that involve dispositions to rash action: sensation seeking, lack of planning, lack of perseverance, positive urgency (the tendency to engage in rash actions when in an extremely positive mood), and negative urgency (the tendency to engage in rash actions when in an extremely negative mood; Cyders & Smith, 2007, 2008b; Cyders et al., 2007; Smith et al., 2007; Whiteside & Lynam, 2001, 2003; Whiteside et al., 2005).
