Title:
Victoria Symptom Validity Test (VSVT)
Short Name:
VSVT
Description:
Victoria Symptom Validity Test (VSVT) is a computerized neuropsychological assessment instrument that is designed to assess the level of cognitive effort during an evaluation. VSVT is a computerized test that uses a forced-choice, two-alternative model to assess possible exaggeration or feigning of cognitive impairments in adults. The 48 VSVT items are presented in three blocks of 16 items each, and items are classified as either easy or difficult. VSVT software administers the test, calculates all scores, and produces a six-page report of the test results.
