Assessment of moral values and behaviors is important in the study of moral development. This study aimed to investigate the psychometric properties of the Moral Behavior Inventory (MBI) and Moral Values Scale (MVS) and to obtain culturally specific instruments. The study sample consisted of 505 healthy college students aged 20 years and above (386 [76.4%] women and 119 [23.6%] men). The participants were asked to complete the sociodemographic data form, MBI, MVS, Scale of Moral Maturity (SMM), Moral Disengagement Scale (MDS), and Moral Value Inventory (MVI). Exploratory factor analysis (principal component analysis and varimax rotation) was applied to the MBI, and it was found that five factors explained 48% of the total variance. Exploratory factor analysis was applied to the MVS (100 items), which originally had 50 items and was added with 50 more culture-specific items, and it was found that four factors explained 42% of the variance. Cronbach’s alpha of the MBI was 0.85, and the Guttman split-half reliability coefficient was 0.83; Cronbach’s alpha of the final 45-item MVS was calculated to be 0.96, and the Guttman split-half reliability coefficient was 0.93. The scores of the MBI and 45-item MVS-final form were significantly correlated with the SMM, MDS, and MVI total score, supporting the concurrent validity of these scales. It was concluded that both scales are valid and reliable measurement tools that can be used in future studies.
