Our test scales are compilations of individual instruments that provide a comprehensive analysis of symptoms and consequences. Using the results of multiple scales, author bias is minimized and a balanced, accurate assessment is provided.

We are dedicated to providing accurate evaluations of behaviors and preventing false indicators. During the last decade, over 10,000 individuals have been tested using these instruments in controlled environments. The database of these test results is available to anyone who would like to verify or further test the validity of these results. References are also available from the hundreds of companies that have used our products. When possible, the test authors have been consulted to insure that the original test scales are properly represented in our compiled instruments and our staff of consultants have reviewed all the test scales we use to insure that our finished instruments designs meet the criteria that was the basis for the validity studies.

We have also reviewed hundreds of other instruments that are currently being used and have found none that were not designed by one individual, or group of individuals, and contain the inherent biases that all such developments contain.

It is for this reason, that we have elected to use a variety of test scales so that each set of biases actually strengthens our compiled instrument results but prevent the false positive results that can occur with single test scales. There may be better marketed assessment instruments than those we use; however, there are none as effective.
