We made the Japanese brief version of the Short Interpersonal Reactions Inventory (SIRI) which aims at measuring the cancer-prone personality. At first, the SIRI was translated into Japanese, which was checked by a bilingual and back-translated by another bilingual. All personnel of a general hospital located in the center of the City of Sendai were asked to respond to the SIRI with some parallel tests, and 485 (of whom 92 were male and 393 female) out of 635 workers answered them. As a result of factor analysis, 4 factors consisting of 5 items each and consistent with the original scale were extracted (which explained 40.1% of total variance). The cancer-prone personality corresponds to the first factor. As a result of correlational analysis with some parallel tests, the first factor was assumed to measure 'harmony seeking' which might be more influential to the occurrence of cancer than the other major trait of cancer-prone personality named 'rationality/anti-emotionality'. Furthermore, it was indicated that the Japanese brief version of the SIRI could discriminate 4 personality types by comparing standardized scores of 4 subscales. It was concluded that a brief questionnaire was developed which can measure a personality trait mainly composed of 'harmony seeking' assumed to be profoundly influential to the occurrence of cancer.
