Test of memory malingering (TOMM) trial 1 as a screening measure for insufficient effort.
The identification of insufficient effort is critical to neuropsychological evaluation, and several existing instruments assess effort on neuropsychological tasks. Yet instruments designed to detect insufficient effort are underutilized in standard neuropsychological assessments, perhaps in part because they typically require significant administration time and are, therefore, not ideally suited to screening contexts. The Test of Memory Malingering (TOMM) is a commonly administered, well-validated symptom validity test. This study evaluates the utility of TOMM Trial 1 as a relatively brief screening measure of insufficient effort. Results suggest that TOMM Trial 1 demonstrates high diagnostic accuracy and is a viable option for screening insufficient effort. Diagnostic accuracy estimates are presented for a range of base rates. The need for more comprehensive SVT assessment in most clinical and forensic situation is discussed.
