Test of Memory Malingering (TOMM)
Please visit this website for more information about the instrument: Test of Memory Malingering (TOMM)
Supplemental: Sport-Related Concussion (SRC) Subacute (after 72 hours to 3 months), Persistent/Chronic (3 months and greater post concussion), and Traumatic Brain Injury (TBI)
Exploratory: Sport-Related Concussion (SRC) Acute (time of injury until 72 hours)
Short Description of Instrument
The Test of Memory Malingering (TOMM) is a widely used 50-item test designed to assess symptom/performance validity. In two learning trials and an optional retention trial, pictures of objects are presented serially to the patient. Following the learning trials, the patient must choose the drawings previously shown in the learning trials.
The test should be administered by trained examiners and can be given by booklet or via computer. Administration time is 15 to 20 minutes for standard administration, plus another 5 to 10 minutes if the optional retention trial is administered.
Sport-Related Concussion Specific:
Advantages: the TOMM instrument has good face validity as a test of learning and memory, decreasing its transparency as an assessment of malingering.
Limitations: Not examined in sport related concussion.Non-verbal memory. Paper and pencil or computer-based.
Age Range: 6–16 years and older
Psychometric Properties
The presentation of 50 pictures provides the TOMM instrument with good face validity as a test of learning and memory, decreasing its transparency as an assessment of malingering. One of the limitations of most malingering tests is the patient's ability to determine the purpose of the evaluation. In research studies, subjects did not suspect that the objective of the TOMM instrument was to detect malingering.
Hand Scoring is used with one point given for each right answer in both phases of the test. Scores range from 0-50.
