Two New Psychometric Instruments One of the major challenges in researching and applying the Cayce approach to healing is the development of a standardized assessment process. Also, the uniqueness of each individual was emphasized, rather than relying solely on diagnostic categories. The disease-centered model, the standard of allopathic medicine, is one approach to this dilemma. The disease-centered model has the advantages of simplicity and public recognition.
Most people are comfortable with defining health problems in terms of diagnostic labels.
However, health problems do not always fall easily into clearly defined boxes. Or, the signs and symptoms do not fit conveniently into any conceptual category. Although Edgar Cayce sometimes used the medical diagnostic language of his day, more often he preferred a person-centered approach to assessment and treatment planning. Cayce's complex system's approach tended to focus more on causes than effects. Thus, the assessment outcome and treatment plan sometimes appeared unrelated to the person's view of the problem.
