| Popis: | Bernard (1990), and Bernard, Houston, and Natoli (1993) identified a discriminant function, derived from Rey figure recall score and RAVLT trial 1 and recognition, which discriminated simulators and controls with 77--85% accuracy. However, in the current study, application of the discriminant function to patients with suspect effort, brain injured patients, and controls, revealed excellent sensitivity (95%) but low specificity (33% for patients, 61% for controls). A new discriminant function using the same Rey figure and RAVLT scores, derived from actual patients with documented suspect effort and patients with confirmed brain injury, resulted in an overall classification of 85% correct, with only 16% of suspect effort and 15% of brain injured patients misidentified. Use of a discriminant function score of/=-.40 resulted in sensitivity of 71% while maintaining specificity of/=91%. |
