Participants were asked three positive urgency items from the abbreviated positive urgency subscale of the UPPS-P (Lynam, Smith, Whiteside, & Cyders, 2006). These items asked each participant to indicate the degree to which he or she tends to lose control when in a great mood; the degree to which others are shocked or worried about the things the participant does when he or she is feeling very excited; and the degree to which the participant tends to act without thinking when he or she is really excited. Responses were made on a four-point scale with the following possible response options: 1 (Disagree strongly), 2 (Disagree a little), 3 (Agree a little), 4 (Agree strongly). Cronbach's alpha for these items was 0.75, and mean scores were calculated for use in analyses.
