Purpose: The purpose of this study was to design emotional and sexual infidelity scenarios and to examine the factor structure and its internal consistency in a sample of Iranian students and staff. Method:In this research, 104 men and 96 women were selected with an average of 19-30 age and using multistage cluster sampling. The researcher-made questionnaire and scenarios are the tools of this research. To construct and validate scenarios, original scenarios related to research patterns translated, initially. In the second step, by interviews with ordinary samples and examples of divorce cases, revealed the areas and issues related to jealousy in Iranian culture. In the next step, with the help of several professor and graduate students, they were examined and corrected. Finally, by introductory run in a sample similar to the previous one,  scenarios  were re-criticized and corrected. Results: In this study, 7 scenarios were obtained which was measured emotional and sexual  infidelity in each of them, separately and was responded according to the Likert pattern, from no disturbing (zero) to very disturbing (seven).  Findings of the exploratory factor analysis revealed two factors ( sexual and emotional jealousy) and the confirmatory factor analysis showed a good fit for this model. The range of the correlation between scenarios varied from 0.15 to 0.75, which was significantly, indicating the good  intrinsic coherence of this tool. Conclusion: The scenarios of emotional and sexual jealousy have the proper factor structure and the good internal consistency.
