The development of the Japanese version of the State Adult Attachment Measure (J-SAAM)

Abstract

The purpose of this study was to develop the Japanese version of the State Adult Attachment Measure (J-SAAM), which measures a momentary level of the sense of attachment security and insecurity, and to examine its reliability and validity. In Study 1 (N = 366), it was confirmed that the J-SAAM, like the original version, has a three-factor structure (security, anxiety, and avoidance) and that each subscale has sufficient internal consistency and criterion validity. In Study 2 (N = 245), participants were divided into Security Priming conditions and Neutral Priming conditions for the intervention. The results showed that the J-SAAM captured a certain degree of temporary fluctuations in the sense of attachment security and insecurity. These results suggest that the J-SAAM has similar properties as the original version and has acceptable reliability and validity.
