Development of a Novel Malingering Detection Method Involving Multiple Detection Strategies

摘要

This study utilized a novel computer-administered measure designed to assess multiple malingering detection strategies, as well as measure genuine impairment in a brain-injured sample. Ninety-four neurologically normal subjects comprised control and simulator groups. Twenty individuals with moderate to severe head injuries comprised a clinical sample. The summary score from the measure yielded a sensitivity of .81 and a specificity of .89. Total completion time and learning curves were utilized as genuine impairment indicators. Sensitivity (.95) and specificity (.95) were quite high for these dimensions. Results suggest there is utility to combining detection techniques, including indicators of genuine impairment.
