eZscore :

a computerized norm selection and scoring program

Overview of eZscore

The eZscore program allows the user to quickly convert raw data from a neuropsychological/neurocognitive evaluation to z-score, T-score and/or percentile equivalents. By entering the patient's demographic information such as age, gender, education, handedness, country of origin, ethnicity, as well as information regarding the test characteristics such as administration and scoring method, the program identifies the 'best-fit' matches for each test administered. The computer program searches the extant normative data base for at least two 'best-fit' matches. Utilizing the norm selection format detailed in The Handbook of Normative Data For Neuropsychological Assessment, the strengths and special considerations regarding the 'best-fit' studies are highlighted so that the clinician can make the most appropriate and informed selection based upon the information available.

eZscore also allows the user to preselect the best norms to use before a patient is examined. This is a very important feature of eZscore, since problems can occur if norms are selected after the patient has been evaluated. Specifically, it is not uncommon to discover after a patient has been evaluated that the test was administered and/or scored differently than the way it was carried out in the 'best-fit' normative sample. Knowing in advance how the 'best-fit' sample was administered the test, and how the test was scored, will allow adjustments in administration and/or scoring to insure a direct comparison of findings.

Once the norms have been selected, and the patient data entered, a summary sheet is printed showing the test raw score, its percentile performance equivalent, and noting the authors of the normative study utilized.

If requested, the program also prints a narrative record of the norms the user did not select, along with the reason why the other 'best-fit' choice was not selected. This information may be useful in forensic applications.

A bibliography of the normative studies used can be generated if requested.

The user can also request a z-score performance profile printout by cognitive domain. The program has the capacity to print test-retest profiles for up to 10 retests. Any combination of retests can be viewed (i.e., compare test 1 with test session 5; or show sessions 1 through 5, etc.).

eZscore will be available soon at http://www.Normativedata.com. Users will need an account number and password to access the program.

One of the main reasons for developing eZscore was to create a standardized template for capturing and recording neuropsychological test data. Since the actual patient data never leaves the user's laboratory when using the eZscore program, archived data can later be accessed to add information regarding final diagnoses. Use of a standardized data collection template will hopefully facilitate research and greatly enhance patient services. Regarding patient services, data from your laboratory or clinic can be rapidly transferred anywhere in the world at the speed of the Internet in a standardized format.
