Over the past 10 years, widespread and concerted research efforts have led to increasingly sophisticated and efficient methods and instruments for detecting exaggeration or fabrication of cognitive dysfunction. Despite these psychometric advances, the process of diagnosing malingering remains difficult and largely idiosyncratic. This article presents a(More)
The Behavior Rating Inventory of Executive Function (BRIEF) is a standardized rating scale that provides information about the nature and extent of executive function deficits displayed by children and adolescents in daily life. BRIEF protocols completed by parents of 80 children with intractable epilepsy were evaluated with respect to prevalence and(More)
A survey addressing practices of 'expert' neuropsychologists in handling financial compensation claim or personal injury litigation cases was carried out. Potential participants were identified by publication history. Responses were obtained from 24 out of the 39 neuropsychologists who were surveyed. Approximately 79% of the respondents reported using at(More)
PURPOSE Based on prior research indicating poor health-related quality of life (HRQOL) in children with attention-deficit/hyperactivity disorder, we investigated (1) whether executive functioning deficits were related to poor HRQOL in children with epilepsy, (2) how important these variables were in comparison to known predictors of HRQOL such as(More)
Health-related quality of life (HRQOL) is an important outcome measure in clinical research. Given the psychosocial and behavioral difficulties associated with pediatric epilepsy, evaluating HRQOL in this patient population is of particular importance. Though HRQOL has been examined in pediatric patients receiving focal resection or pharmacological(More)
A computer-administered memory test was given to normal subjects instructed to feign brain damage, normal controls, and traumatic brain-injured (TBI) patients with complaints of memory dysfunction. The test, a revised version of an instrument developed by Hiscock and Hiscock (1989) employed forced, two-choice recognition of previously presented five-digit(More)
Error scores and response times from a computer-administered, forced-choice recognition test of symptom validity were evaluated for efficiency in detecting feigned memory deficits. Participants included controls (n = 95), experimental malingerers (n = 43), compensation-seeking patients (n = 206), and patients not seeking financial compensation (n = 32).(More)
The utility of measures for detecting malingering was evaluated using a simulation design in which half the participants were encouraged to do their best and half were asked to feign head injury. Particular attention was focused on the utility of repeated assessment (intraindividual variability) in discriminating the groups. Participants were tested on(More)
Normative data for neuropsychological tests are often presented in the form of percentiles. One problem when using percentile norms stems from uncertainty over the definitional formula for a percentile. (There are three co-existing definitions and these can produce substantially different results.) A second uncertainty stems from the use of a normative(More)
Clinical norms for the 64-item Wisconsin Card Sorting Test (WCST-64) are presented. The norms were derived from 303 persons presenting for emergency services who met criteria for uncomplicated mild head injury. Most data were obtained within 2 days of injury, and the remaining data were obtained within 10 days of injury. The norms may be used to help(More)
