Greyson NDE Scale
Quantifying the phenomenon
Professor & Psychiatrist Bruce Greyson developed this scale to measure the depth of an individual’s near-death experience. The following is a copy of the scale as presented in an article entitled "Altered States" by Lee Graves in the Summer 2007 edition of the University of Virginia Magazine.
1. Did time seem to speed up or slow down?
2. Were your thoughts speeded up?
3. Did scenes from your past come back to you?
4. Did you suddenly seem to understand everything?
5. Did you have a feeling of peace or pleasantness?
6. Did you have a feeling of joy?
7. Did you feel a sense of harmony or unity with the universe?
8. Did you see, or feel surrounded by, a brilliant light?
9. Were your senses more vivid than usual?
10. Did you seem to be aware of things going on elsewhere, as if by extrasensory perception (ESP)?
11. Did scenes from the future come to you?
12. Did you feel separated from your body?
13. Did you seem to enter some other, unearthly world?
14. Did you seem to encounter a mystical being or presence, or hear an unidentifiable voice?
15. Did you see deceased or religious spirits?
16. Did you come to a border or point of no return?
A score of 7 or higher is considered a NDE for research purposes. The mean score among a large sample of near-death experiences is 15.
The following appendage on scoring was not included in the above article - see references listed below.
Sum of all 16 items = total NDE Scale score
Among a criterion group of NDErs, the mean score on this scale was 15 with a standard deviation of 7.84; we therefore use a score of 7 or greater (1 standard deviation below the mean) as the cut-off point for identifying an experience as an NDE.
Sum of items 1-4 = cognitive component
Sum of items 5-8 = affective component
Sum of items 9-12 = paranormal component
Sum of items 13-16 = transcendental component
SCORING TYPE OF NDE:
Cognitive type = cognitive component score 5 or higher
Transcendental type = cognitive component score less than 5 and transcendental component score 5 or higher
Affective type = cognitive and transcendental component scores each less than five, and affective component score 5 or higher
Paranormal type = cognitive, transcendental, and affective component scores each less than 5, and paranormal component score 5 or greater
Unclassifiable = no component score 5 or greater
