The aim of this study is to develop a Communicative Rational Action Scale and analyze its validity and reliability. The scale has been prepared for all administrators and especially for firm administrators based on Max Weber’s rationalizing theory and Jürgen Habermas’ communicative action theory. The scale reveals to what extent administrators’ behaviors are communicatively rational while deciding or acting. In total, 282 participants joined this study. The sample group consisted of senior administrators of 87 firms acting in Turkey’s different Organized Industrial Zones or Free Zones. Data were analyzed by the SPSS 21 and AMOS 22 programs. Exploratory factor analysis and confirmatory factor analysis were applied to the obtained data. In order to test item discrimination, total item correlations were calculated and items under the value of 0.40 were removed from the scale. Exploratory factor analysis revealed 21 articles and five factors. The correlation coefficient of the 21-article scale with a similar scale is 0.979 (p < 0.001). The Cronbach’s alpha value is 0.945 and the test–retest correlation parameter is r = 0.793 (p < 0.001). In conclusion, it was determined by confirmatory factor analysis that the Communicative Rational Action Scale has a good cohesion criterion, and it is a valid and reliable assessment instrument.
