Clinical utility of the memory complaints inventory to detect invalid test performance.
This investigation was designed to examine the classification statistics of Memory Complaints Inventory (MCI) scores relative to the Medical Symptom Validity Test (MSVT) and the Non-Verbal Medical Symptom Validity Test (NV-MSVT), as well as various validity scales on the Personality Assessment Inventory (PAI) and Minnesota Multiphasic Personality Inventory-2 Restructured Form(MMPI-2-RF).



The sample consisted of 339 active duty service members with a history of concussion who completed performance validity tests (PVTs), symptom validity tests (SVTs), and the MCI.



Those who failed the MSVT and NV-MSVT had significantly higher scores across all MCI scales. In addition, those who scored above specified cut scores on the evaluated PAI and MMPI-2-RF validity scales also had significantly higher MCI scale scores. Receiver operator characteristics analysis demonstrated acceptable area under the curve (AUC) across the evaluated SVTs for the mean of all MCI subtests with values ranging from (.77 to .86), with comparable findings for PVTs (MSVT AUC = .75; NV-MSVT AUC = .72).



In general the MCI scales demonstrated better classification statistics relative to SVTs vs. PVTs, which is consistent with the nature of the MCI as a self-report instrument.
