The purpose of this study was to examine the relationships between MMPI(Minnesota Multiphasic Personality Inventory) scale and safety and health related indices in the shipbuilding workmen. The MMPI scores of the 230 shipbuilding workmen applicants and their performance records regarding safety and health were analyzed through t-test and one-way ANOVA to obtain the following results; (1) applicants intended to show the positive characteristics of their personality, and this attitude reflected a decrease on T-scores of MMPI; (2) there were significant relationships between some MMPI subscales and safety & health related indices. These results can be used to provide baseline information for more effective accident prevention programs.
