From a sample of 345 college students completing the Dissociative Experiences Scale (DES), the authors interviewed twenty-two students scoring below 5.0, and twenty students scoring above 22.6
with the Dissociative Disorders Interview Schedule, and also administered the SCL-9O and Millon Clinical Multiaxial Inventory to them. High and low scorers on the DES were clearly differentiated on all three measures. Seventy per cent of the high DES scores had a DSM-III-R dissociative disorder, while none of the low scorers did. Extrapolation from the data yields a prevalence of DSM-III-R dissociative disorders among college students of 11.0%.
