|---|
The relative usefulness of two digit span (DS) variables in detecting negative response bias, as defined by below cut-off performance on the Test of Memory Malingering (TOMM), was examined among primarily middle-aged military veteran outpatients who were judged clinically to be at increased risk for displaying negative response bias on cognitive testing. Digit span variables included DS Age Scaled Score (DS Age SS) and Reliable DS. Findings from this retrospective data analysis (N = 46) suggest that DS Age SS is preferable for use over Reliable DS in predicting TOMM failure. Results of the current study suggest that, particularly if the Wechsler scales are an existing part of the neuropsychological assessment, examination of DS Age SS is an efficient means of detecting negative response bias.
