The Gitaigo Personality Scale (GPS; Komatsu et al., 2012) consists of 60 mimetic words comprising six subscales, and is used for measuring self and others' personality. In this study we developed a short form of the GPS, the GPSsf which consists of 30 words, by selecting the five words that exhibited the highest loadings for each of the GPS six factors. A factor analysis showed that the GPSsf consisted of six factors consistent with the six subscales of the GPS. The GPSsf had relatively high test-retest reliability, internal consistency, and sufficient validity. Because of the reduced number of items, the GPSsf is now more accessible for use in assessment situations.
