Cross Cultural Studies on DID

It is important to note that one cannot conclude DID does not exist in a country if no prevalence study has been done there. Statements by individual therapists that it does not exist or is rare do not constitute a prevalence study. Also, surveys of therapists questioning how many DID patients they have diagnosed is not a prevalence study. So far, to date, prevalence studies have universally found the presence of DID, with symptom expression very similar in each case.

Those with strong dissociative tendencies were followed up with the DDIS. Prevalence rate of 15.2 for Dissociative disorders in general, and 6.7% (n=7) for DID. Only 2 of the DID cases had been previously diagnosed. There was a 15.2% (n=16) prevalence rate for DD, inclusive of DID. Only 3 of the 16 cases, including the 2 DID cases, had been previously identified.Clinical profiles resembled those described in the North American literature.
