Despite recent advancements in the theory and assessment of maximization, only outdated scales of maximization have been available in Japanese. Based on the two-component model of maximization, I translated into Japanese the Maximizing Tendency Scale and the alternative search subscale of the Maximization Inventory as indexes of high standards and alternative search, respectively, and also tested the validity of both scales. The results of exploratory and confirmatory factor analyses and item response theory revealed considerable internal reliability for both scales. The correlation analyses depicted a significant positive relationship between the Maximizing Tendency Scale and the Multidimensional Perfectionism Cognition Inventory as predicted, implying external validity of the Maximizing Tendency Scale as an index of high standards. Conversely, the Maximization Inventory did not correlate with the General Procrastination Scale, though a positive correlation was expected between alternative search and procrastination tendency. However, considering that correlations between the two factors of maximization and psychological traits were hardly reported, the result is not decisive.
