Intraindividual variability as an indicator of malingering in head injury.

Cognitive complaints in patients after whiplash injury: the impact of malingering.

OBJECTIVES The validity of memory and concentration complaints that are often reported after a whiplash trauma is controversial. The prevalence of malingering or underperformance in post-whiplash patients, and its impact on their cognitive test results were studied. METHODS The Amsterdam short term memory (ASTM) test, a recently developed malingering test, was used as well as a series of conv...

The effects of coaching on the sensitivity and specificity of malingering measures.

This study sought to identify patterns of performance indicative of malingering on the Auditory Verbal Learning Test (AVLT). Participants were randomly assigned to perform normally, simulate head injury, or simulate head injury with warning that there might be attempts to detect malingering. Participants completed an expanded AVLT and a forced-choice task, in addition to several other memory te...

Intraindividual Variability 1 Running head: INTRAINDIVIDUAL VARIABILITY Describing Intraindividual Variability at Multiple Time Scales Using Derivative Estimates

The study of intraindividual variability is central to the study of individuals in psychology. Previous research has related the variance observed in repeated measurements (time series) of individuals to trait–like measures that are logically related. The use of intraindividual measures such as intraindividual standard deviation or the coefficient of variation are likely to be incomplete repres...

Exploration of malingering indices in the Wechsler Adult Intelligence Scale-Fourth Edition Digit Span subtest.

Prior research shows that Digit Span is a useful embedded measure of malingering. However, the Wechsler Adult Intelligence Scale-IV (Wechsler, 2008) altered Digit Span in meaningful ways, necessitating another look at Digit Span as an embedded measure of malingering. Using a simulated malingerer design, we examined the predictive accuracy of existing Digit Span validity indices and explored whe...
