Two studies aim to determine the psychometric properties of the Czech version of The Self-Importance of Moral Identity Scale (Aquino, Reed, 2002). The scale consists of nine moral personality qualities that measure two dimensions of moral identity: internalization and symbolization.
For the analysis, we chose the authors' 13-item scale originally proposed. Based on the statistical analysis in the pilot study (n = 163), we excluded from the original scale two items that did not meet the established psychometric criteria.
In the second study, on a different set of respondents (n = 185), we subsequently verified the degree of internal consistency of the adjusted 11-item scale. We measured construct validity using tools measuring moral untying and cheating at work.
Based on the results obtained in our study, we recommend considering the proposed eleven-item alternative of the questionnaire for use in the Czech population, for which we found sufficiently good basic psychometric characteristics.
