The assessment of effort is an important aspect of a comprehensive neuropsychological evaluation, as this can significantly impact data interpretation. While recent work has validated the appropriateness of adult-derived cutoffs for standalone effort measures in younger populations, little research has focused on embedded effort measures in children. The present study includes 54 clinically referred children and adolescents (32 males/22 females; aged 6-17) with a confirmed diagnosis of epilepsy. Reliable Digit Spans (RDSs) were calculated and the Test of Memory Malingering (TOMM) was administered in the context of a comprehensive neuropsychological evaluation. Using a previously published RDS cutoff of ≤6, a pass rate of only 65% was obtained, well below the recommended 90% pass rate for an effective effort index. In contrast, when adult criteria were used on TOMM Trial 2, a 90% pass rate was observed. RDS scores were significantly correlated with IQ estimates (r = .59, p < .001) and age (r = .61, p < .001). The difference between RDS and the TOMM on the participant outcome was statistically significant (χ(2) = 9.05, p = .003). These results suggest that RDS appears to yield a large number of false positives and, therefore, may be of limited utility in detecting poor effort in a pediatric epilepsy population. These findings likely extend to other pediatric populations that are known to have significant cognitive loss.

Assessment of executive functioning in childhood epilepsy: the Tower of London and BRIEF.

Child Neuropsychol 2012 3;18(4):404-15. Epub 2011 Oct 3.

Children and adolescents with epilepsy are known to demonstrate executive function dysfunction, including working memory deficits and planning deficits. Accordingly, assessing specific executive function skills is important when evaluating these individuals. The present investigation examined the utility of two measures of executive functions-the Tower of London and the Behavioral Rating Inventory of Executive Functioning (BRIEF)-in a pediatric epilepsy sample. Ninety clinically referred children and adolescents with seizures were included. Both the Tower of London and BRIEF identified executive dysfunction in these individuals, but only the Tower of London variables showed significant relations with epilepsy severity variables such as age of epilepsy onset, seizure frequency, number of antiepileptic medications, etc. Further, the Tower of London and BRIEF variables were uncorrelated. Results indicate that objective measures of executive function deficits are more closely related to epilepsy severity but may not predict observable deficits, as reported by parents. Comprehensive evaluation of such deficits, therefore, should include both objective measures as well as subjective ratings from caregivers.
