The Dissociative Experiences Scale (DES II)‚ the 1993 revised version (Carlson & Putnam‚ 1993) is a 28-item self report measure of the frequency of dissociative experiences. The change in the DES II (Carlson & Putnam‚ 1993) is considered to "be so minor that we feel confident that the  new version will yield results comparable to those of the old version .

Note: This version of the DES‚ which is the one used most frequently in my laboratory‚ is essentially the same as the "DES II" provided by Carlson & Putnam (Dissociation‚ 1993)‚ with very minor changes to the wording of the instructions.  The 11-point Likert-type response scale for the DES II is far more convenient than the 10-centimeter visual analogue scale of the original DES‚ especially for large-scale testing sessions.
