Brief screening indexes for malingering: A confirmation of Vocabulary minus Digit Span from the WAIS-III and the Rarely Missed Index from the WMS-III.

This study investigated the specificity of empirically derived screening measures for the detection of symptom exaggeration in persons with a diagnosis of alcohol abuse (n = 30), polysubstance abuse (n = 43), or head trauma (n = 27). The first measure evaluated was Vocabulary (V) minus Digit Span (DS) (Mittenberg, Theroux-Fichera, Zielinski, & Heilbronner, 1995); the second measure was the Rarely Missed Index (RMI) for the WMS-III Logical Memory subtest (Killgore & Della-Pietra, 2000). V-DS misclassified 0% of individuals in the alcohol abuse group, 2% of those in the polysubstance abuse group, and 0% of head injury cases. RMI misclassification rates were 3%, 5%, and 7% for the alcohol abuse, polysubstance abuse, and head injury groups, respectively. Overall accuracy rates were 99% for V-DS and 95% for RMI.

Malingering of memory impairment on the Colorado Priming Test.

OBJECTIVES: We hypothesized that simulated malingerers would show a weaker priming effect and a longer response latency than control patients and patients with a brain injury on a priming test. DESIGN: Participants were compared on their performance on the Colorado Priming Test to replicate and extend the original validation study. METHODS: Of 33 participants, 16 were people with a brain injury and 17 were non-head injured control patients who were also instructed to feign cognitive impairment (simulators N = 17). RESULTS: Up to 88 per cent of simulating malingerers and 75 per cent of head-injured participants were correctly classified. CONCLUSIONS: The Colorado Priming Test may be useful in identifying patients feigning memory impairment.

HIV malingering in the accident and emergency department.

This paper reports a number of cases of patients attending an accident and emergency (A&E) department claiming to be HIV positive when they have been tested negative and are known to be negative by other departments in the hospital. The reasons for these patients claims are not always apparent. These patients may place an inappropriate workload on an already busy department. We caution doctors working in A&E departments to be vigilant when dealing with patients who claim to be HIV positive when there are no clinical or laboratory findings to substantiate the claim and we recommend liaison between relevant departments within a hospital and the patient's general practitioner (GP) when dealing with these patients.

Feigned HIV infection/AIDS: malingering and Munchausen's syndrome.

Feigned HIV infection or acquired immunodeficiency syndrome (AIDS), in which people mimic infection with or disease due to HIV, accounted for 1.7% of admissions to our specialist HIV unit in Central London over a 5 year period. Of 12 patients with feigned HIV/AIDS, 11 were HIV antibody-negative, and one refused testing. Presenting histories were sometimes grandiose, unusually tragic, or unlikely in relation to the patients' healthy appearance, and often included admissions to other specialist HIV units. Substance abuse was suspected in over half of the patients described, a higher frequency than that observed in our HIV-infected patient population. The possibility of feigned HIV/AIDS should be remembered in persons with self-reported HIV infection. Recognition of this condition is important to avoid costly and potentially dangerous investigation and therapy.
