Abstract
Scale for corruption perceptions measurement is tested in this paper. Tested scale is used in a survey for The Global Competitiveness Report by the World Economic Fo-rum. It is also used in constructing the CPB Index (Corruption Perceptions of Business Index). Reliability, discriminant and convergent validity, and dimensionality of a scale are analyzed. Reliability of a scale is tested with Cronbach alpha coeffi cient, Alpha-if-deleted indicator and item-to-total correlation. Discriminant and convergent validity is tested with exploratory and confi rmatory factor analysis. Dimensionality is tested with confi rmatory factor analysis, with previous dimensionality check with exploratory factor analysis. Re-sults undoubtedly indicate that analyzed measurement scale has satisfactory psychometric characteristics and that it is an adequate measurement instrument for measuring and re-searching corruption perceptions
