The Epworth Sleepiness Scale (ESS) is a scale intended to measure daytime sleepiness that is measured by use of a very short questionnaire. This can be helpful in diagnosing sleep disorders. It was introduced in 1991 by Dr Murray Johns of Epworth Hospital in Melbourne, Australia.
The Dissociative Experiences Scale (DES) was developed by Eve Bernstein Carlson, Ph.D. and Frank W. Putnam, M.D. The overall DES score is obtained by adding up the 28 item scores and dividing by 28: this yields an overall score ranging from 0 to 100. Copies of the DES can be obtained through the Sidran Institute.
