[Standardization of the Japanese-language version of the Structured Interview for Disorders of Extreme Stress (SIDES)].

The reliability and validity of the Japanese version of Structured Interview for Disorders of Extreme Stress (SIDES) were evaluated in a group of normal subjects (n=60) and a group of victims of interpersonal trauma (n= 53). SIDES was developed in the United States in 1997 and is a tool for assessing Disorders of Extreme Stress Not Otherwise Specified (DESNOS). Self-reporting and semi-structured versions of the SIDES have been developed. Cronbach's alpha coefficient for the self-reporting version was .92 for an individual's lifetime, and .85 for the present. Cronbach's alpha coefficient for the semi-structured interview version was .95 for an individual's lifetime, and .88 for the present. Using the Dissociative Experiences Scale (DES) and physical symptom scale as external standards, the validity of SIDES was confirmed. Although the present results indicate that the Japanese version of SIDES has good internal reliability and validity, it remains necessary to conduct further research on more victims of many kinds of trauma.
