The correct usage of the DES-T: Demonstrating the use of big data in an analogue study of adolescents

This study discusses the correct usage of the DES_T by utilizing big data from analogue study of adolescents. The DES-T was derived from Dissociative Experiences Scales (Bernstein & Putnam, 1986), which was developed to assess severe dissociative symptoms. EMDR training strongly recommends screening for dissociative disorders, and the DES has been introduced as one of the assessment tools for this purpose. However, misuse of DES-T is rampant and it is important to disseminate the correct usage. Therefore, we gave a detailed explanation of the observed differences between the average of the 28 items of DES and the probability calculated from DES-T, and compared the distributions between those of DES and DES-T correctly calculated. In addition, an optimum cutoff value is inferred from a combination of the DES's cutoff value and the DES'T's probability. Furthermore, information is presented to acquire the appropriate tools for calculating the DES-T.
