Detecting memory performance validity with DETECTS: A computerized performance validity test.

Evaluating performance validity is essential in neuropsychological and forensic assessments. Nonetheless, most psychological assessment tests are unable to detect performance validity and other methods must be used for this purpose. A new Performance Validity Test (DETECTS - Memory Performance Validity Test) was developed with several characteristics that enhance test utility. Moreover, precise response time measurement was added to DETECTS. Two groups of participants (normative and simulator group) completed DETECTS and three memory tests from the Wechsler Memory Scale III. Simulators achieved considerably lower scores (hits) and higher response times in DETECTS compared with the normative group. All participants in the normative group were classified correctly and no simulator was classified as having legitimate memory deficits. Thus, DETECTS seems to be a valuable computerized Performance Validity Test with reduced application time and effective cut-off scores as well as high sensitivity, specificity, and positive and negative predictive power values. Lastly, response time may be a very useful measure for detecting memory malingering.
