The CTIP is a fast, effective tool developed to evaluate the extent that various neurological injuries have affected the speed information is processed in certain individuals. It can be used with individuals ranging from 15 to 74 years of age, and is applicable to clinical and research settings. The CTIP has the functionality to aid in the detection of malingering of cognitive deficits frequently associated with Traumatic Brain Injury, by providing converging evidence that a respondent is not putting forth maximum effort.

How to Use the Assessment
The CTIP consists of three computerized subtests that measure reaction time. The subtests progressively increase the amount of information being processed in order to systematically record individual reaction times and the reports provide summarized scores for each subtest. Total administration time takes approximately 15 minutes and the CTIP runs on the MHS SmartLink™ system where users have the ability to choose from clinical or research reports.
