TDB2Online

TDB2Online consists of an app and this accompanying wiki.

The TDB2OnlineApp is a web application for visualizing neuropsychological test data. The program is an online spin-off of TDB2, a database application that has been used since 2009 in the Psychological section of the Department of Psychiatry and Psychotherapy, University Hospital, LMU Munich, to present and interpret psychological test results. Both applications were developed by Rolf R. Engel (psychometrics) and Ralf Mayr (programming).

The TDB2OnlineWiki describes the methodological background and the functionality of the TDB2OnlineApp, as well as the processing work on the individual tests.

Most pages of the TDB2Online Wiki have been translated into English; Claude did the bulk of the work using Opus 5.5, based on a detailed glossary; Deepl was used for occasional additions. I take responsibility for any remaining errors. Language (German or English) can be selected with the flag icon in the top row. The figure captions and the app (input and output) are still in German. Some explanations have been added to the English texts for readers who are not familiar with the German tests or the German versions of internationally available tests.

TDB2Online is aimed at psychologists who administer, score, and interpret psychological ability tests in adults in a clinical context. Fields of application in which TDB2Online can be useful are psychodiagnostic, and in particular neuropsychological, examinations of patients with mental disorders.

The internet application TDB2Online provides input forms for entering raw test scores. Based on systematically revised normative data, the program calculates standardized performance scores and presents them together with age reference values in a profile sheet. The output is a PDF file; for an example, see below (click to enlarge).

Users of TDB2Online must have the right to administer and score the respective tests. For tests protected by copyright, this right is generally acquired by purchasing the test material (manual and consumables). Purchase is almost always restricted to certain professional groups. For some classic neuropsychological tests, no (current) rights holder can be identified. In the detailed descriptions of the tests in the TDB2OnlineWiki, the copyright situation for each test is presented to the best of our knowledge.

TDB2Online uses its own algorithms to transform the normative data of the included tests into a uniform profile display. The calculations are explained in detail for each test in the TDB2OnlineWiki; they vary in scope from test to test. In any case, they go so far that TDB2Online cannot be regarded as a reprint of existing norm tables protected by copyright. If, contrary to our view, a rights holder sees unauthorized use of parts of a test in the TDB2Online application, please let us know (see Legal notice and contact)

Access to the TDB2OnlineApp and to the documentation of the tests is reserved for professional users of the tests, that is, in general, psychologists and, in special cases, professionals from other occupational groups working in clinical psychodiagnostics. For this purpose, we ask by email for information about the professional background of newly registered persons who wish to gain access. No usage fee is charged.

The general TDB2Online documentation and some parts of the test descriptions are accessible to the public. The texts of the website are organized as a wiki in order to stimulate discussion. Participating in the forum is restricted to registered users.

The particular features of TDB2Online are explained in the following texts:

1. A one-page explanatory sheet describes in very brief form what can be seen on the profile sheet. In a clinic, this explanatory sheet could, for example, be passed on to the party requesting the report. The sheet also contains a reference to the detailed description of the background in the TDB2Online wiki.
2. There is also a nine-page introduction to the essential concepts and procedures behind TDB2Online.
3. The detailed documentation of the general concepts and procedures is accessible under the button Documentation, the detailed documentation of the tests under the button App and test documentation, both in the navigation pane.

TDB2Online can display the results of the following tests:

Rolf R. Engel developed the test profile based on performance scores, compiled the tests norms, adapted them to the profile, and wrote all of the documentation. Ralf Mayr designed the data base and programmed the inhouse-based-application TDB2 and its web version, TDB2OnlineApp.

We would like to thank Natalie Werner and Franziska Meister for help with some of the test descriptions. We would like to thank Eva Etschel for her contribution to the statistical processing of test norm data. We also would like to thank Wolfgang Weise for his help with the former in-hospital hardware and to the LMU-Klinikum for the present hosting.
