Early Cutoff Criteria for Strong Performance on the Test of Memory Malingering

The Test of Memory Malingering (TOMM) is widely used to assess performance validity. To improve efficiency, we investigated whether abbreviated administration (i.e., only the first 25 items of Trial 1 [T1]) is possible when effort is very strong (≥49/50 on T1 or T2). We collected TOMM scores of 501...

Description
Summary:The Test of Memory Malingering (TOMM) is widely used to assess performance validity. To improve efficiency, we investigated whether abbreviated administration (i.e., only the first 25 items of Trial 1 [T1]) is possible when effort is very strong (≥49/50 on T1 or T2). We collected TOMM scores of 501 consecutive adult patients ranging in cognitive status who underwent standard neuropsychological evaluation at Mayo Clinic, Rochester, MN. Receiver Operating Characteristic (ROC) analysis showed excellent area under the curve (AUC) (0.94; CI95% [0.92, 0.97]) and a cutoff of 25/25 had 100% specificity for identifying strong performance. Of the 224 patients who obtained a perfect score on the first 25 items, 197 (88%) obtained ≥49 on T1 and the remaining patients (n = 27) obtained ≥49 on T2. A perfect score on the first 25 items of the TOMM predicted overall strong performance 100% of the time, supporting abbreviated administration in select cases in a general outpatient clinical setting.
