DESCRIPTION:Aims: The objective of this cross-sectional study was to exami
 ne the utility of\nmultiple symptom validity tests (SVTs)\, including symp
 tom-based measures\n(Cambridge Memory Questionnaire-CMQ and Kapur’s Modi
 fied Rey Memory Test-ModRey) and a performance-based memory test (Rivermea
 d Post-concussion Questionnaire-RPQ)\, in a sample of test-coached simulat
 ors.\n\nMethod: Forty-two undergraduate students were recruited and random
 ly assigned to control (n=21) or test coaching (n=21) condition. All parti
 cipants were administered the above-mentioned SVTs. Inter-test correlation
 s were assessed by partial correlations. Receiver operating characteristic
  (ROC) curve analysis was used to determine optimal cutoff scores of each 
 SVTs and combinations of multiple SVTs.\n\nResults: RPQ was found to be co
 rrelated with CMQ and ModRey. CMQ did not correlate with ModRey. Results o
 f ROC analyses suggested optimal cutoff score for CMQ-69\, RPQ and the qua
 litative score of ModRey were 81/82\, 24/25 and 0/1\, yielding specificity
  ranging from 95% to 100% and sensitivity ranging from 76% to 95%. Using a
  combination of all three SVTs obtained a cutoff of 1/2 (failing two or mo
 re SVTs)\, yielding a high specificity (100%) and sensitivity (91%).\n\nCo
 nculsions: Our findings lend support to the use of multiple independent SV
 Ts to detection memory malingering. However\, the evaluation procedure tes
 ted in this study should be used as an adjunct screening procedure rather 
 than as a diagnostic assessment.
