General Discussion of Instruments
and How to Interpret
The CCIS and ATLI project involved the use of three
psychometric instruments. Here is a brief discussion of each instrument
with an explanation of how to use the normative data to interpret scores.
The SF-36 is a general health inventory that has
been well researched and serves as a benchmark for the other two instruments
that we are researching. You can compare your scores to the norms
for this questionnaire by locating the physical score and mental score
on the right, middle portion of the summary sheet under the columns with
those headings. To make it easier to identify these scores, we have
highlighted them with a marker. The average score is 50. Scores
above 50 are indicative of greater health. Conversely, scores below
50 suggest a relative lack of health.
The use of the SF-36 questionnaire allows us to compare
our sample to norms established by the Rand Corporation using thousands
of individuals across the United States. We were happy to report
that the data from our project corresponds closely to the norms established
for this instrument. This means that our data is likely to represent
a valid sample.
Cayce Comprehensive Symptom Inventory (CCSI)
The CCSI scores are divided into 30 scales that correspond
to patterns of etiology (cause and effect) described in the Edgar Cayce
health readings. The summary page for your CCSI data contains a table
with scores for each scale along with normative scores derived from the
total sample. Thus you can compare your score to the median (50th
percentile), 25th percentile and 75th percentile. Lower scores are
indicative of better health.
The CCSI summary sheet also contains two graphs.
The global score graph illustrates how your total CCSI score compares to
25th, 50th, and 75th percentiles. Lower scores are indicative of better
The scale score graph visually displays the data
in the table with respect to each scale score. The red line
represents your scores. Lower scores are indicative of better health.
The CCSI seems to be more sensitive to "dis-ease"
than some instruments such as the SF-36 which are designed to measure more
severe disability associated with "disease." Thus it is possible
to have a relatively normal SF-36 and yet still have a CCSI that indicates
some areas for concern that could benefit from preventative measures to
avoid serious illness later.
At this time, the CCSI is a research instrument used to produce hypotheses
for further assessment. If you would like to learn more about the
specific scales, the Meridian Institute website contains brief descriptions
of each scale what your scores may mean. The website also contain
a CCSI Workbook and Manual with extensive documentation
on how the scales were constructed and what each is intended to measure.
Approach to Life Inventory (ATLI)
The ATLI is intended to measure mental and spiritual
factors as described in the Edgar Cayce readings. As with the CCSI,
the summary sheet for this instrument provides you with a table that lists
scale scores compared to the median, 25th and 75th percentiles.
There are two ATLI graphs. The first one shows
your data (red line) as compared to the median, 25th and 75th percentiles.
Generally, higher scores are indicative of better health.
The second graph represents your responses to specific
health-related items. Except for "neglect," higher scores on this
graph are indicative of increased resources for dealing with health-related
We will continue to collect data and do statistical
analysis of these instruments. We are also using them for individual
assessments at the HRRC Assessment Center. In a few months a summary
report will be published on the Meridian Institute website.
