Cogtest Library

Cogtest provides sponsors with an unrivaled library of the highest quality computerized cognitive tests in addition to computerized versions of gold standard batteries.

All the tests in the Cogtest library have been and continue to be developed by academic neuropsychologists and clinical trial specialists. This ensures that the most recent developments in cognitive neuroscience, including neurophysiological functioning and neuro-imaging evidence are incorporated into the Cogtest library of tests and procedures.

The tests tap microcognitive abilities for increased sensitivity specific to drug effects, predictive of functional outcomes.

There are over 80 publications of individual tests and batteries in the Cogtest library.

Tests of verbal ability, social cognition, and emotion recognition are unique to the library.

  • Computerized BACS (Brief Assessment of Cognition in Schizophrenia)
  • Computerized CGI-CogS (Clinical Global Impression of Cognition in Schizophrenia)

The Cogtest Equivalent of the MATRICS Battery

The MATRICS initiative sought to provide a uniform battery of cognitive tests for use in clinical trials with schizophrenia patients. In response, Cogtest offers currently available and well-standardized (including normative comparison data) subtests that are equivalent or identical to those proposed by the MATRICS committee. The additional advantages of the Cogtest version is that all the tests have been used in clinical trial programs, they are available in 60 languages, and the battery incorporates all the advantages of computerized testing. The estimated time for completion of the MATRICS battery is 90 minutes while the estimated time for completion of the Cogtest MATRICS version is 60 minutes.
