Development of the Multidimensional Scale of Jealousy in Romantic Relationship

Abstract

There are no useful scales that assess romantic jealousy multidimensionally in Japanese, and also, many issues that need improvement can be noted in representative jealousy scales such as the Multidimensional Jealousy Scale by Pfeiffer & Wong (1989). This study was conducted to develop the Multidimensional Scale of Jealousy in Romantic Relationships to assess components of romantic jealousy referred to in previous studies and to make some improvements. Three components of romantic jealousy were hypothesized: suspicious cognition, exclusive emotion, and cautious behavior. The results from 234 undergraduates showed three factors indicated by exploratory/confirmatory factor analysis and high internal consistency. The results also showed concurrent validity with the “Mania love style” and construct validity with scales measuring fear of abandonment, reassurance-seeking, and intimacy.
