Objective: to investigate how scales for the concept of moral virtues are constructed and measured, in studies associated with business ethics and the tradition of virtue ethics. Methods: a systematic literature review was conducted to select empirical articles on moral virtues that design or apply scales. Based on search, selection, and analysis criteria, five databases were consulted, and 37 papers were selected, with subsequent analysis of the scales development and measurement procedure (items, sample, factor analysis) and emerging factors. Results: the study gathers scales of multiple moral virtues (19) and of specific virtues (18), showing limitations in the generation of items, and in the item-sample proportion in some scales, as well as theoretical contributions in leadership and relationship strengthening, making a theoretical and methodological discussion in the light of the assumptions of virtue ethics in the Aristotelian-Thomistic tradition. Conclusions: the article intends to contribute to a better understanding of moral virtues in management, by discussing the scales from the unity of virtues and the phronesis-moral virtues connection, with implications for human behavior and business ethics. Procedures are recommended for future qualitative and quantitative studies in new research contexts.
