Assessing dissociative identity disorder (DID) can be difficult, particularly because individuals with this disorder often produce extreme elevations on validity scales on some personality tests and interviews.
        The goal for this study was to provide information about how to distinguish genuine versus feigned DID on widely used personality tests and interviews.
        A group of SCID-D-R diagnosed DID patients completed the Minnesota Multiphasic Personality Inventory (MMPI-2) and a forensic gold standard interview, the Structured Interview of Reported Symptoms (SIRS/SIRS-2). In these three papers, we compare the data from the DID group to that from feigners who were exposed to hours of training about DID (i.e., coached simulators) as well as to a feigning group that was not coached about DID (i.e., uncoached simulators).
         Across the papers, the coached group generally was better able to imitate DID than was the uncoached group. However, neither group was highly successful in feigning DID. Given that well-coached individuals could not successfully imitate DID on well-established psychological tests, this series of studies provides support for the trauma model of dissociation as well as for the construct validity of DID.
          Furthermore, the results will help assessors and forensic experts better distinguish genuine from feigned DID.

  1. Hi Jeannette,

    I hope your new year is going well. Am I reading this correctly and it actually supports a pro-d.i.d. position? I think my wife would have a hard time faking her disorder perfectly. Life is too unpredictable to be “in character” 100% of the time as your positions suggests. I see her at all times of the day, in all situations. It’s not impossible but pretty improbable.

    Any way, take care!

    • Hello, Sam. Best to you this New Year, as well!

      Yes, this article supports DID. It was a presentation at the International Society for the Study of Trauma & Dissociation by Bethany Brand. I do not hold either the ISST&D or Brand in high esteem. Brand’s studies are not well designed & the ISST&D supports it which does not do them justice as a credible source. IMO
