The material below is taken from the SCI Manual, and provides information targeted to data collected from groups of meditators based on length of practice—beginning, intermediate, long term, and very long term (over 20 years). In the manual, these groups are discussed under each of the scales, and compared with other populations researched. It is summarized here just for convenience. The entire SCI Manual, with studies of all the different populations researched, and reliability and validity studies, can be found at
