ABBREVIATED FORM OF THE TEST OF MEMORY MALINGERING

The Test of Memory Malingering (TOMM) is a neuropsychological effort test in which scores below 45 on Trial 2 or Retention Trial indicate insufficient effort on testing, but Trial 1 score is not used. This study attempted to identify Trial 1 cut points above and below which further trials need not be administered. Data were analyzed from 114 patients referred for clinical neuropsychological evaluation. Sensitivity, specificity, and positive and negative predictive value for identifying failure on TOMM were calculated. Trial 1 scores ≥36 indicated 99% likelihood that TOMM would be passed; Trial 1 scores ≤27 indicated 100% likelihood of failure.
