The Schuhfried VTS enables computer-assisted application of a large number of highly diverse psycho-diagnostic tests and measuring procedures. In developing the system much emphasis was placed on transparent structure and largely uniform design. It is therefore simple to operate and easy to understand and does not require any special computer skills.
The VTS basic module is required for administration of any of the available tests.
The Schuhfried VTS supports the administration of both single tests and test batteries. Many of the single tests are available in different test versions. These test versions may differ, for example, in terms of test duration or difficulty or may be parallel forms. They are characterized by different parameters reflecting specific test requirements. They have been designed for administration to a specific population (e.g. psychiatric patients, children, etc.) or for special measuring purposes (e.g. repeated measurements). Test batteries are compiled from the available single tests and test versions.
The DTKI combines the proven test concept of the Determination Test with a multi-media mode of presentation which is especially designed for children.
Measurement of reactive stress tolerance and reaction speed and assessment of attention deficits in situations requiring continuous, swift and varying responses to rapidly changing visual and acoustic stimuli. As a children's version of the well-established Determination Test (DT) the DTKI combines a measurement method which has proved its success over many years with an innovative and childfriendly mode of presentation.
Main areas of application: Educational psychology, school psychology, neuropsychology, clinical psychology, psychopharmacology, sport psychology, and assessment of motor ability.
The DTKI is used to measure reactive stress tolerance and the associated ability to react. The test requires the subject to use his cognitive skills to distinguish colours and acoustic signals and to memorise the relevant characteristics of stimulus configurations, response buttons, and assignment rules. The difficulty of the DTKI arises from the need to sustain continuous, rapid, and varying responses to rapidly changing stimuli.
The test involves the presentation of coloured stimuli and acoustic signals. The child reacts by pressing the appropriate buttons on the response panel. The stimuli are presented adaptively - that is, the speed of presentation adapts to the ability level of the child. The use of headphones ensures the exclusion of unwanted noise.

The test yields scores for the variables "correct responses", "incorrect responses", "omitted items", "median reaction time", "number of stimuli", "on time response", "delayed responses", and "reactions".
Depending on the age group, the internal consistency for the main variable lies between α=0.86 and α=0.94.
Results for the content validity of the DT are also applicable to the DTKI. Further studies of the validity of the test are currently being undertaken.
The DTKI has been normed on a sample of 545 schoolchildren (271 male, 274 female) age 6 – 14.
Approx. 6-8 minutes including instruction and practice phase.
