Development and Validation of Moral Behavior Inventory: the Facts related to Confirmatory Factor Analysis and Exploratory Factor

The purpose of this study was to develop and validate a Moral Behavior Inventory (MBI). For this purpose, 40 items associated with moral behavior were designed using the comments presented by six experts and tested along with the Big Five Personality Traits Inventory (BFI), Ethical Sensitivity Scale Questionnaire (ESSQ), and Minnesota Multiphasic Personality Inventory (MMPI) on 329 undergraduate students. The results of the exploratory factor analysis as well as the confirmatory factor analysis (after the removal of 8 items) supported the eight-factor structure of the MBI which includes respect to differences, being considerate, responsible behavior, helping behavior, humble behavior, aggressiveness, cheating  behavior, and caring behavior. The evidences related to convergent validity and internal reliability indicated the psychometric capacities of MBI. On the whole, the results of the present study introduced the 32- item inventory of moral behavior as an appropriate tool for conducting research in the field of morality.
