The present study attempted to incorporate several tests that had specific indices for identifying memory malingering into a battery for the assessment of memory malingering. Two measures, a famous faces test and a subjective memory questionnaire were constructed originally by the author. These measures were pilot-tested on a group of demented community geriatric participants (n=10) and control geriatric participants (n = 12). Three indices indicative of memory malingering in Hong Kong List Learning Test (HKLLT) were explored. The indices of the HKLLT, the two new measures and the Test of Memory Malingering were incorporated into a battery for detection of memory malingering. Using an analogue design, the battery was tested on a group of community participants (N = 58) who were randomized into two conditions, simulated malingering (SM) condition (n = 25, one was excluded because of non-compliance to experimental instructions) and true effort (TE) condition (n = 32). Participants in the SM group were given instruction to exaggerate memory complaints after a hypothetical head injury while the TE condition instructed participants to do his/her best. The subjects were tested on 6 measures of the battery and 2 other tests. A manipulation check was also completed. The results indicated significant difference between the two conditions on all the measures. The cut-off scores of the measures attained sensitivity from .4 to .84 and specificity of .9 to 1. Using discriminant analysis, the overall hit rate was 93% and using logistic regression, the overall hit rate was 98%. The measures were then tested on a group of depressed patients (N = 39) who were randomized into SM (n = 19) and TE condition (n = 20). Manipulation check indicated that about 80% of depressed participants of SM group were unable to comply with malingering instruction. Analysis was then done to compare the performance of community SM sample (n = 25) with community TE sample (n = 32) and depressed TE sample (n = 20). Results found significant difference between simulated malingering and control and depressed sample respectively. No significant difference was found between community control and depressed sample. Using the cut-off scores obtained from the normal sample, specificity of depressed sample on 3 measures was lowered. Using discriminant analysis and logistic regression, two-group classification (simulated malingering and non-simulated malingering) reached an overall hit rate of 92% and 94% respectively. Using 4 indictors of the battery achieved sensitivity of 68%, specificity of 100 % in normal control and 100% in depressed sample. The effect of depression, base rate of malingering in affecting the classification, the issue of use of simulation in research design and future research direction was discussed. / Chang Suk Yi Sonia. / "July 2006." / Adviser: Agnes Chan. / Source: Dissertation Abstracts International, Volume: 68-03, Section: B, page: 1919. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2006. / Includes bibliographical references (p. 156-179). / Electronic reproduction.

The FBS (Lees-Haley, 1992) is a relatively new validity scale for the MMPI-2 designed specifically to detect feigned neurocognitive deficit. The aim of the present study was to examine the FBSs efficacy in differentiating psychiatric and neurocognitive feigners using a known-groups design. Malingering tests were administered to 180 individuals undergoing forensic neuropsychiatric evaluations. Based on the malingering test results, participants were classified as honest responders, psychiatric feigners, neurocognitive feigners, or feigning both psychiatric and neurocognitive deficits. The FBS significantly differentiated the 3 feigning groups from the honest group, but it did not discriminate effectively between neurocognitive and psychiatric feigners.

College students may feign symptoms of ADHD to gain access to stimulant medications and academic accommodations. Research has shown that it can be difficult to discriminate malingered from genuine symptomatology, especially when evaluations are based only on self-report. The present study investigated whether the average student given no additional information could feign ADHD as successfully as those who were coached on symptoms. Similar to Jasinski, Harp, Berry, Shandera-Ochsner, Mason, & Ranseen (2011) and other research on feigned ADHD, an extensive battery of neuropsychological, symptom validity, and self-report tests was administered. Undergraduates with no history of ADHD or other psychiatric disorders were randomly assigned to one of two simulator groups: a coached group which was given information about ADHD symptoms or a non-coached group which was given no such information. Both simulator groups were asked to feign ADHD. Their performance was compared to a genuine ADHD group and a nonclinical group asked to respond honestly. Self-report, neuropsychological, and effort test performance is discussed in the context of the effect of coaching and regarding its implications for ADHD evaluations.

Detection of malingering is a significant concern in forensic psychological assessments. The best-validated tests currently available are time-intensive for both test-takers and mental health professionals. Thus, well-validated, brief screening measures for malingering would be useful in a forensic environment. The Structured Inventory of Malingered Symptomatology (SIMS; Smith andamp; Burger, 1997) has demonstrated potential in this role. The present study attempts replication of previous studies while extending validation from analogue and male criminal forensic samples to both men and women in a civil forensic setting. The SIMS accuracy in the detection of both neurocognitive and psychiatric symptom feigning is evaluated by comparing its performance to stringent multi-scale criterion measures in a large forensic sample. Cut scores suggested by previous studies yield high sensitivity and negative predictive power in this sample when the SIMS is used to detect psychiatric symptom malingering; however, these cut scores perform inadequately here when screening for the feigning of neurocognitive impairment, and no alternative cut score functions well in this capacity. The results lend support to the utility of the SIMS as a screen for psychiatric symptom malingering by men and women in a civil forensic setting.

The current study examined the efficacy of various neuropsychological measures for differentiating ADHD and comorbid ADHD from malingered ADHD in a large state university sample. The sample consisted of 23 nonclinical individuals assigned to malinger ADHD (NLM), 9 nonclinical individuals responding honestly (NLH), 22 individuals with diagnoses of ADHD only (ADHD-H), 9 individuals with comorbid ADHD/Learning Disorder presentations (ADHD-LD), and 13 individuals with comorbid ADHD/Anxiety presentations (ADHD-ANX). Due to limited sample sizes, the ADHD-LD and ADHD-ANX participants were pooled to create a comorbid ADHD group (ADHD-CO n = 22). The study utilized a simulation design with a NLM group instructed to feign ADHD while the other groups responded under standard instructions. The TOMM, LMT, NV-MSVT, and CTIP variables performed well, but the DMT did not. The WAIS-IV and WJ-III variables did not adequately differentiate malingered and comorbid ADHD.

Malingering has become an increasing concern in neuropsychological assessment in recent years, and a wide range of tests have been designed and examined for the purpose of detecting malingering. Cut-off scores have been recommended for these tests in order to provide indications of malingering performances. However, the derived scores have been in respect of westernised populations of people with relatively high levels of education who speak English as their first language. Accordingly, the current study aimed to attain normative data and cut-off scores for four commonly employed neuropsychological tools, administered in English, on a population of black, South African, Xhosa-speaking people (N = 33), who attended a former DET-type school in the Eastern Cape, with a Grade 11-12 level of education, in the age range of 18 - 40 years. The targeted measures included the TOMM, the Rey-15 Item Memory Test, the Digit Span subtest of the WAIS-III, and the Trail Making Test. The obtained scores were poorer than the previously published cut-offs for at least one component of each of the tests investigated, except the TOMM. The fmdings of this study highlight the important role that the factors of culture, quality of education, and language play in neuropsychological test performance.

Given the prevalence and cost of low back pain, particularly among workers' compensation patients, it is advantageous to understand how various psychological constructs may be related to prolonged disability and failure to return to work. Malingering is a psychological construct that is clearly relevant for worker compensation populations and is a construct that is well suited for experimental control within an analog study. Malingering is the intentional exaggeration of physical or psychological symptoms that are motivated by external incentives such as time away from work. The ability to detect malingering in such a population with psychological assessments is unclear. An analog study was conducted in which we instructed college students to portray themselves as injured workers who received a back injury that required them to be off work while they recovered. Students were then told that they would be seeing a psychologist who would attempt to ascertain their abilities to return to work via the MMPI-2. Students were then randomly instructed to respond to the MMPI-2 in three different ways: a control condition was instructed to respond as if they suffered a workplace back injury that resulted in significant pain; a subtle fake-bad condition who received the control instruction plus were informed they did not enjoy their work and their back injury allowed them to enjoy personal and family time more; and a fake-bad condition that received the control instruction plus were asked to deliberately portray themselves as experiencing physical symptoms severe enough to keep them off work longer. Currently, no assessment of malingering exists within a compensated low back pain population. The purpose of this study was to determine if the MMPI-2 can be used to differentially identify "patients" who are instructed to report symptoms veridically versus "patients" instructed to consciously feign and magnify symptoms in an effort to avoid returning to work. Malingering and non-malingering patients' scores on the MMPI-2 validity and clinical scales were subjected to a cluster analysis to determine if a malingering profile could be accurately identified. A 5-cluster validity solution and 4-cluster clinical (both with K correction) solution were accepted. Substantially lower scores on L and K, elevated scores on F on the 5-cluster validity solutions, distinguished the "malingering" profile. The 4-cluster clinical solution was characterized by elevated scores on the clinical scales of hypochondriasis, depression, paranoia, and schizophrenia, which distinguished the "malingering" profile. The results indicate that the MMPI-2 could be useful in detecting malingering in compensated back pain patients. Results are discussed in the context of pain studies.
