Introducing a forced choice recognition trial to the Hopkins Verbal Learning Test - Revised

Objective This study was designed to replicate previous research on embedded validity indicators (EVIs) in the Hopkins Verbal Learning Test - Revised (HVLT-R) and introduce a new forced choice recognition trial (FCR). Method Undergraduate research volunteers were randomly assigned (M-Age= 21.7;M-Education= 14.5 years, 85% female) to either the control or experimental malingering condition, and were administered a brief battery of neuropsychological tests. Results Recognition memory based EVIs (both existing and newly introduced) effectively discriminated credible and non-credible response sets. An FCR <= 11 produced .59 sensitivity and perfect specificity to invalid responding. A Recognition Discrimination (RD) score <= 8 also produced a good combination of sensitivity (.35) and specificity (.96). The FCR trial made unique contributions to performance validity assessment above and beyond previously published EVIs. Conclusions RD achieved >=.90 specificity at higher cutoffs than previously reported. The newly introduced FCR trial has the potential to enhance the existing arsenal of EVIs within the HVLT-R. However, it must demonstrate its ability to differentiate genuine impairment from non-credible responding before it can be recommended for clinical use.
