Theoretical conceptualizations and research (Carducci, 1999; Cheek & Krasnoperova, 1999; Melchior & Cheek, 1990) assert that shyness consists of three components: physiological (affective), cognitive, and behavioral. The purpose of the present study was to replicate and validate the three-component model of shyness as assessed by a Japanese translation of the 20-item Cheek-Buss Shyness Scale (CBSS) (Cheek& Melchior, 1985). The participants were students from four universities who completed a Japanese translation of the CBSS. The results of a factor analysis of the Japanese CBSS yielded three oblique factors (r>0.62), but it was infinitesimally one factor structure (alpha>0.89). Such findings support previous factor analytical research suggesting that "a single dimension underlies the construct of shyness" (Jones, Briggs, & Smith, 1986, p. 638) and the three-component model of shyness. In support of the importance of replication research (Maxwell, Lau, & Howard, 2015), this Japanese version of the CBSS demonstrates high construct validity.
