Retrospective Analysis of the Test of Memory Malingering in a Low Intellectual Quotient Intractable Epilepsy Sample

The Test of Memory Malingering (TOMM) is commonly used by neuropsychologists (Sharland, M. J., & Gfeller, J. D. (2007). A survey of neuropsychologists' beliefs and practices with respect to the assessment of effort. Archives of Clinical Neuropsychology, 22 (2), 213-223); however there is variable research regarding its use in low intelligence and epileptic populations (Hill, S. K., Ryan, L. M., Kennedy, C. H., & Malamut, B. L. (2003). The relationship between measures of declarative memory and the Test of Memory Malingering in patients with and without temporal lobe dysfunction. Journal of Forensic Neuropsychology, 3 (3), 1-18; Hurley, K. E., & Deal, W. P. (2006). Assessment instruments measuring malingering used with individuals who have mental retardation: Potential problems and issues. Mental Retardation, 44 (2), 112-119; Simon, M. J. (2007). Performance of mentally retarded forensic patients on the Test of Memory Malingering. Journal of Clinical Psychology, 63 (4), 339-344). The present study evaluates whether the standard TOMM cutoffs are resistant to low estimated IQ (≤80) in a clinical sample of patients with intractable epilepsy. A second aim is to decipher possible relationships between the TOMM and memory performance.
