Performance of psychiatric inpatients and intellectually deficient individuals on a task that assesses the validity
Abstract:
A brief psychological screening test, devised by Rey (1964), was developed to assess the validity of memory complaints. Although Rey hypothesized that malingerers would be mislead to perform poorly while even individuals with severe concentration problems could succeed, a review of the literature did not reveal any empirical reports that examined the actual performance of nonmalingering though disturbed patients. Therefore, Rey's test was administered to samples of acutely disturbed psychiatric patients (N = 50) and intellectually deficient individuals (N = 16). The results confirmed the criterion proposed by Lezak (1983) and suggested that malingering should be considered among individuals who deny remembering at least 9 of the 15 times of the Rey test.
