In this study we developed a “Scale of Diversity Adaptability” which measures the social skills to accept cultural diversity. First, we revealed the components of the evaluation measure of Diversity Adaptability. The components were collected by accumulating elements related to diversity using the methods of literature review, interview, and brainstorming. In addition, we built a tentative assessment by using the method of group discussion. Second, we decided the component names and defined the components, to clarify the relationship between the components. Third, we created questions regarding each component. Evaluation of validity of the scale was carried out by the following methods; individual item analysis, item-correlation analysis, path analysis, and confirmatory factor analysis. The reliability of the scale was evaluated by Crombach′s alpha. As a result, the validity and reliability were evaluated for the 8 factors and 29 items scale. Using the developed scale, we measured the effect of the Blind-Soccer workshop. In particular, we carried out a test of factor scores before and after the workshop implementation. As a result, a significant increase was observed in the 6 factors. It is a force that shows personality, ambitions, bird′s-eye view force, resilience, trust relationship building force, and communication. Altogether, the results of our study clearly showed that we have developed a “Scale of Diversity Adaptability” which can enable the evaluation of the current situation and measures related to adaptability. Furthermore, we were able to confirm its usefulness. By using this scale as a standard assessment tool, it is believed that it is possible to contribute to the development of society as a whole through encouraging diversity adaptability.
