Abstract
Rationale
The Test of Memory Malingering (TOMM) is a commonly utilized performance validity test currently recommended for pediatric use with children as young as 5 years of age. Yet, a small sample of children struggles to pass the TOMM due to true cognitive difficulties. The systematic search and review identified the reported cases of false positive and overall failing TOMM performance in children. The goal of this project was to increase the understanding of the cognitive constructs and minimum cognitive abilities necessary for children to pass the TOMM. The secondary goal was to use the existing data to suggest clinical guidelines related to use of the TOMM with children.
Methods and Results
A comprehensive search of PubMed/MEDLINE, EMBASE, Web of Science, and PsycINFO was conducted, returning an initial 12,052 results. After duplicate articles were removed, 10,583 remained; 61 were evaluated for eligibility and 22 were included as our final sample. Results suggested that false positives were observed in children with low IQ, memory issues, complex medical presentation, and younger children.
Conclusions
Without relevant, quality validation and normative studies, the TOMM should not be used clinically with young children or children suspected of having significant cognitive issues. Failing performance on the TOMM does not necessarily indicate poor effort or invalidate the neuropsychological profile. Instead, it may be reflective of other factors, particularly in children below age 6, children with lower intellectual abilities (especially FSIQ ≤ 75), children with multiple diagnoses, or children with more severe neurological diagnoses. Clinical recommendations are also discussed.
