摘要：Background: Romantic jealousy is a complex construct composed of several dimensions. Given the multidimensional nature of romantic jealousy, it would be useful to have a measurement scale that would take into account its several components. Objective: The aims of the present study were to provide the Italian adaptation of the Short Form of the Multidimensional Jealousy Scale (SF-MJS - Elphinson, Feeney & Noller, 2011) verifying its factorial structure, reliability, and predictive validity. Finally, gender differences in the tree main dimensions of romantic jealousy- cognitive, emotional and behavioral- were explored. Method: 361 participants (168 males and 193 females), aged 20 to 40 (M = 26.50; SD = 4.99) were recruited. A confirmatory factor analyses (CFA) was performed to test the multidimensional structure of the scale. Cronbach’s alpha coefficient was used to verify the reliability. The predictive validity was assessed examining associations between different dimensions of the romantic jealousy and insecure romantic attachment. Multivariate analysis of variance (MANOVA) was implemented in order to verify gender differences. Results: Confirmatory factor analyses verified the three-factor structure, supporting the presence of these distinct latent constructs, assessing cognitive, emotional and behavioral components of romantic jealousy. The internal consistency coefficients were satisfactory for all the three factors of the scale, and ranged from .80 to .85. Consistent evidence supported the predictive validity of the ISF-MJS. Significant gender differences were registered. Conclusion: The ISF-MJS constitutes a reliable instrument for measuring romantic jealousy in the Italian context. Limitations, strengths, and further development of the present study are discussed.
