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.
 

SF-36

    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 health.

    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 issues.
 

Future Research

    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.
