The present study investigated how trait anxiety influenced the formation of a self-frame and decision making. Participants (N = 1044) responded to the Trait Anxiety Inventory. Those with trait anxiety scores ±1 Z score from the sample mean (N = 328) were recalled to respond to the self-frame questionnaire. The results suggested that trait anxiety differences could result in differences in the editing of decision-making information, thereby influencing the risky choice. Compared with the low trait anxiety group, participants from the high trait anxiety group showed a greater tendency to use negative vocabulary to construct their self-frame and tended to choose conservative plans. Self-frame suppressed the influence of trait anxiety on decision making. These results further confirmed the hypothesis that individual differences in personality traits might influence the processing of information in a framed decision task.
