Validation Studies Summary

Dr Hartman constantly reminded his students ‘ The proof of the pudding is in the eating’. In other words, regardless of how logical, rigorous or beautiful a system of thinking might be, if the system does not provide usable and testable results, the it does not have the right to be called a science. There are four keys to a science.

A science is:

1. Based on objective observations, which are independent of any one subjects perspective.
2. Based on a mathematical measuring system.
3. Universally applicable.
4. Subject to empirical testing to confirm the observations.

As a result the applications of science must be valid and reliable.

The science of Axiology, founded by Dr. Hartman, meets all four of these conditions. The science is based on formal value theory generated by Hartman’s value mathematics. The Axia Profile is an application of  Hartman’s Axiology. As such, it is based on value mathematics. Moreover, the norm for the profile is generated prior to statistical evaluation of profile responses and results from the logical relations of the value system.

A large number of research projects have been undertaken by both value scientists  (Axiologists), psychologists and statisticians to confirm the validity of the Hartman Norm and model, and to substantiate the reliability of the instrument and to demonstrate the usability of the results from profiles based on it.

Standard statistical validation consists of three types of validation studies:

Construct Validity –

examines the instrument itself and determines that all of the items on the instrument are relevant and have the prescribed effect on the area or concept that the measure. Does the profile measure what it is supposed to measure?

Concurrent Validity –

is obtained by correlating an instrument to other industry accepted instruments.

Criterion Validity –

demonstrate that the instrument can be used as a valid predictive measure within a specific application or discipline.

Confirmation studies in all three of the above areas have been undertaken and approved. In addition, internal and external studies have been conducted and validated by the E.E.O.C to confirm that the Hartman Value Profile and its results are reliable and do not discriminate either by age, race or sex.
