PURPOSE: The purpose of this study was to measure (the degree of) injury risk perception in preschool children. METHODS: The data were collected from child day care centers and kindergartens located in Seoul, and Gyeonggi and Kwangwon Province. A questionnaire consisted of 28 pictures was administered to 186 preschool children. RESULTS: The mean score for the injury risk perception was 21.83 (+/-3.89), and 77.98 converted into a 100-point scale. According to sub-categories, 'burn prevention' (.96+/-.13) was the highest, 'interpersonal safety' (.44+/-.31) was the lowest. There were significant differences in injury risk perception according to gender (t=-2.358, p=.019), age (t=-2.101, p=.037), experience of safety education (t=-3.719, p<.001), area of residence (t=-3.445, p=.001), injury experience (t=3.212, p=.002), and mother's occupation (t=-4.858, p<.001). The highest item in the percentage of correct answer item was 'making jump on the desk', the lowest item in the percentage of correct answer item was 'not wearing safety equipment when rollerblading'. CONCLUSION: Based on this study, studies should be continued to standardize the instrument. In addition, it is recommended that an injury prevention education program should be developed based on the results of this study to stimulate demand and interest.
