In contrast, VOC-DS was especially weak in both sensitivity and specificity, with an apparent false positive rate of 28.

Reliable Digit Span (RDS) is a calculation of the sum of the highest number of digits forward on which both trials are correct plus the highest number of digits backward on which both trials are correct (Greiffenstein et al., 1994). Evaluating subjects believed to be investing full effort in testing, it was found that both Digit Span and Reliable Digit Span had high specificity, although both showed relatively lower sensitivity.Reliable digit span did not differentiate simulators from nursing home residents. Symptom Validity Tests (SVTs) and Performance Validity Tests (PVTs) are frequently used in the. Scores of 7 or lower suggest poor effort or negative response bias. Sensitivities were moderate and specificities were excellent. Reliable Digit Span (RDS) is an indicator used to assess the validity of cognitive test performance. All information provided by the listing agent/broker is deemed reliable. Reliable digit span contrasts between simulators and each of the other groups demonstrated that reliable digit span discriminated controls and elderly from simulators (≤6 and ≤5 cutoffs). 100,000 square feet of resort-like amenities that span three full floors of. Sensitivities were low and specificities were excellent. Rows were fair predictors using a ≤2 cutoff. Total score was a fair predictor of dissimulation using a cutoff ≤ 8. Nursing home residents could not cope with the 15-Item Test and were dropped. Using a previously published RDS cutoff of 6, a pass rate of only 65 was obtained, well below the recommended 90 pass rate for an effective effort index. On the 15-Item Test, controls and elderly performed similarly and were combined. Reliable Digit Spans (RDSs) were calculated and the Test of Memory Malingering (TOMM) was administered in the context of a comprehensive neuropsychological evaluation. Participants were controls (n = 15), healthy volunteers instructed to simulate memory impairment (n = 12 5 of 17 volunteers did not comply with instructions and were dropped), healthy elderly (n = 12), and cognitively disabled nursing home residents (n = 8). Abstract: The Rey 15-Item Test and reliable digit span were evaluated in Japan.Using the RDS as a measure of performance validity among individuals presenting with a possibility of dementia increases the risk of misinterpreting genuine cognitive impairment as invalid performance when higher cutoffs are used lower cutoffs may be useful when interpreted in conjunction with other measures of performance validity.Īssessment Dementia Malingering/symptom validity testing Reliable Digit Span. Those scoring below cutoffs performed worse on cognitive measures compared with those falling above cutoffs. One-way ANOVA was used to compare performance on a cognitive screening measure and informant reports of functional independence of those falling below and above cutoffs.Ī cutoff score of ≤7 resulted in a high prevalence of below-criterion performance (29.7%), though an RDS of ≤6 was associated with fewer below-criterion scores (12.8%) and prevalence of an RDS of ≤5 was infrequent (4.3%). RDS is a measure of effort rst derived from the Digit Span subtest of the Wechsler Adult Intelligence Scale-Revised (WAIS-R Wechsler, 1981). Score distributions were examined to establish the base rate of below criterion performance for RDS cutoffs of ≤7, ≤6, and ≤5. The RDS was calculated for each participant in the context of a comprehensive neuropsychological assessment completed as part of routine clinical care. The current study evaluated performance of the RDS in a clinical sample of 934 non-litigating individuals presenting to an outpatient memory disorders clinic for assessment of dementia. An RDS score of ≤7 is commonly referenced as indicative of invalid performance however, few studies have examined the classification accuracy of the RDS among individuals suspected for dementia. The Reliable Digit Span (RDS) is a well-validated embedded indicator of performance validity.
