Are we documenting performance validity testing in pediatric neuropsychological assessments? A brief report

ABSTRACT

A 2016 survey of pediatric neuropsychologists found that 92% of clinicians reported use of “at least one” performance validity test (PVT) in each assessment. The present investigation sought to verify documented PVT use among clinicians by review of actual reports. A convenience sample of pediatric neuropsychological reports of children ages 6–17 were reviewed over an 24-month period (January 2015–January 2017); reports were those seen as part of our routine practice, including reports on children we were reevaluating, cases that we consulted on, or cases evaluated elsewhere presenting to our centers that required record review for clinical decision making (e.g., presurgical epilepsy evaluations). A total of 131 reports, from 102 unique neuropsychologists were reviewed. PVT usage was documented in only six reports, from six unique clinicians, representing only 4.58% of the reports (or 5.88% of clinicians), far below expectations recent survey results. Though sampling differences and documentation factors may account for some of this disparity, a “social desirability bias” on surveys is likely a major factor in explaining these discordant findings.
