Development of Japanese version of the Situational Interdependence Scale

Interdependence is among the most pervasive characteristics of human social life. The Situational Interdependence Scale (SIS) is a multi-dimensional scale comprising five factors: mutual dependence, power, conflict, future interdependence, and information certainty. These factors explain behavior in interdependent situations. Although translations of the SIS exist in several languages, a Japanese iteration of the instrument has yet to be prepared. Therefore, this study aims to develop a Japanese version of the SIS (SIS-J). In Study 1 and 2, the original version of the SIS was translated into Japanese and the factor structure of the SIS-J and reliability were verified. Study 3 examined whether the SIS-J could measure differences in situations between the Dictator game and the Prisoner’s Dilemma game. Results indicate that the factor structure of the SIS-J was equivalent to that of the original version and that differences in situations between the two economic games could be measured. These results suggest that the SIS-J can be used in measure recognition of the interdependent situations.
