[The construction, reliability and validity of a Japanese Need for Closure Scale]

The purpose of this study was to develop a Japanese Need for Closure Scale. In Study 1, Webster and Kruglanski's (1994) Need for Closure Scale was translated into Japanese, and administered to 240 undergraduates. Factor analysis of the Japanese version indicated that a three-factor structure was most appropriate. In Study 2, a revised scale was developed based on the result of Study 1, and administered to 577 undergraduates. Analysis of the revised Japanese Need for Closure Scale showed that it had sufficient internal consistency and test-retest reliability. In addition, confirmatory factor analysis indicated that the scale had a multidimensional structure. In Study 3, the scale was administered together with five relevant personality scales to 340 undergraduates, and sufficient construct validity of the scale was demonstrated.
