DETAILS:
The VSVT is a computerized test that uses a forced-choice, two-alternative model to assess possible exaggeration or feigning of cognitive impairments.
The VSVT software administers the test, calculates all scores, and produces a six-page report of the test results.
Large, full-page color graphs of your client’s VSVT performance, as well as graphs of the performance of relevant comparison groups, can be easily printed for display.
The 48 VSVT items are presented in three blocks of 16 items each, and items are classified as either easy or difficult.
The Total Items Correct score is used to classify a respondent’s performance; the type and number of items answered correctly, the response latency, and the right-left preference scores provide information that can be used to help interpret VSVT performance.
Test interpretation compares the respondent’s performance to what is expected to occur on the basis of chance alone; this binomial-based approach to respondent classification minimizes the risk of false positives.
Research results confirm the clinical and forensic utility of the VSVT for identifying respondents who are attempting to exaggerate or feign cognitive impairments.
