METHODS: By cluster sampling, 214 cadets from a military academy were investigated with Modified Big Five Personality Scale and selfdesigned decisionmaking scale. The cadets were randomly divided into 2 groups. After noneffective questionnaires were eliminated, the first group (n=110) were in a positive framing and the second group (n=104) in a negative framing. A chisquare test was used to analyze the results of program chosen and t test was used to determine the relationship between personality dimension and risky choice.
