Assess for Poor Effort, Deliberate Feigning, or Exaggeration of Real Cognitive Deficits


The VSVT is a performance validity test that uses a forced-choice, two-alternative model to assess possible exaggeration or feigning of cognitive impairments.

Features and benefits

  • VSVT scores help to indicate that factors other than cognitive impairment may be influencing a client’s performance.
  • 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.
