This study attempted to determine the prevalence of dissociative identity disorder in the general population.
The Dissociative Experiences Scale (DES) was administered to 994 subjects in 500 homes who constituted a representative sample of the population of Sivas City, Turkey.
The mean DES score was 6.7 ± 6.1 (mean ± SD).
Of the 62 respondents who scored above 17 on the DES, 32 (51.6%) could be contacted during the second phase of the study.
They were matched for age and gender with a group of respondents who scored below 10 on the scale, and the Dissociative Disorders Interview Schedule (DDIS) was then administered to both groups.
Seventeen subjects (1.7%) received a diagnosis of dissociative disorder according to the structured interview.
In the third phase, eight of 17 subjects who had a dissociative disorder on the structured interview could be contacted for a clinical evaluation.
They were matched with a nondissociative control group and interviewed by a clinician blind to the structured interview diagnosis.
Four of eight subjects were diagnosed clinically with dissociative identity disorder, yielding a minimum prevalence of 0.4%. Dissociative identity disorder is not rare in the general population.
Self-rating instruments and structured interviews can be used successfully for screening these cases. (...)
