Apparent effect of type of compensation seeking (disability versus litigation) on performance validity test scores may be due to other factors.

Neuropsychologists use performance validity tests (PVTs; Larrabee, 2012 ) to ensure that results of testing are reflective of the test taker's true neurocognitive ability, and their use is recommended in all compensation-seeking settings. However, whether the type of compensation context (e.g.

Cross validation of the Lu and colleagues (2003) Rey-Osterrieth Complex Figure Test effort equation in a large known-group sample.

A Rey-Osterrieth Complex Figure Test (ROCFT) equation incorporating copy and recognition was found to be useful in detecting negative response bias in neuropsychological assessments (ROCFT Effort Equation; Lu, P. H., Boone, K.

The Warrington Recognition Memory Test for words as a measure of response bias: total score and response time cutoffs developed on "real world" credible and noncredible subjects.

Several studies have examined the usefulness of the Warrington Recognition Memory Test-Words as a measure to detect suspect effort, although samples have generally been small and/or comprised of simulators rather than "real world" credible and noncredible patients. The current study examined the Warrington Recognition Memory Test-Words total score and response time of "real world" noncredible patients (as determined by motive to feign, failure on > or =2 independent measures of response bias, low cognitive scores inconsistent with normal ADLs; n = 190) versus credible patients (as determined by no motive to feign, failure of < or =1 measure of response bias; n = 124) derived from an archival database of individuals from the Harbor-UCLA Medical Center, Department of Psychiatry, Outpatient Neuropsychology Service, and the private practice of the second author. Noncredible patients obtained significantly lower total scores and longer times to complete the task.

Interpreting the meaning of multiple symptom validity test failure.

While it is recommended that judgments regarding the credibility of test performance be based on the results of more than one effort indicator, and recent efforts have been made to improve interpretation of multiple effort test failure, the field currently lacks adequate guidelines for using multiple measures of effort in concert with one another. A total of 103 patients were referred for outpatient neuropsychological evaluation, which included multiple measures of negative response bias embedded in standard test batteries. Using any pairwise failure combination to predict diagnostic classification was superior (sensitivity = 83.

Utility of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) in patients with end-stage liver disease awaiting liver transplant.

Unlabelled: Cognitive impairment is common among patients with end-stage liver disease (ESLD). This study examined cognitive dysfunction in patients with ESLD using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).

Method: 66 patients with ESLD awaiting liver transplant were recruited.

Effect of interferon-alpha on cognitive functioning in patients with chronic hepatitis C.

Treatment with interferon-alpha (IFN-alpha) has been shown to adversely affect cognitive functioning in patients with a variety of medical disorders, but information about the effects of IFN-alpha on cognitive functioning in patients with chronic hepatitis C (CHC) is limited. The purpose of this study was to examine the effects of IFN-alpha on neuropsychological test performance in CHC patients. Participants were 30 patients with CHC, 11 who underwent IFN-alpha therapy and 19 who did not.

Cognitive functioning and psychiatric symptomatology in patients with chronic hepatitis C.

Hepatitis C virus (HCV) infection is a major public-health-care problem, with over 170 million infected worldwide. Patients with chronic HCV infection often complain of various cognitive problems as well as symptoms of depression, anxiety, and fatigue. Relatively little is known, however, about the specific cognitive deficits that are common among HCV patients, and the influence of psychiatric symptomatology on cognitive functioning.
