Using a sample of individuals undergoing medico-legal evaluations (690 men, 519 women), the present study extended past research on potential gender biases for scores of the Symptom Validity (FBS) scale of the Minnesota Multiphasic Personality Inventory-2 by examining score- and item-level differences between men and women and determining the extent to which FBS scores were able to correctly identify men and women who were divided into credible responders (n = 837) and noncredible responders (n = 372) on the basis of performance on symptom validity tests. Results indicated that women had slightly higher raw FBS scores than men (d = 0.29), and significant differences between men and women in item endorsement were demonstrated for 14 FBS items. Step-down hierarchical logistic regression procedures indicated predictive bias (chi[superscript 2]Delta = 23.72, p less than 0.001). Follow-up analyses indicated intercept bias (chi[superscript 2]Delta = 23.51, p less than 0.001) but not slope bias (chi[superscript 2]Delta = 0.22, p = 0.64). However, using the test publisher's recommended FBS cutoff scores (Ben-Porath, Graham, & Tellegen, 2009), classification accuracies were similar for women and men (T greater than 80, h = -0.02; T greater than 100, h = -0.22, respectively). On the basis of these results, we conclude there is no evidence of clinically meaningful bias in predictions of symptom validity test failure made using FBS scores for men and women.
