Efficacy of the three Randomness Validity Scales for the Jesness Inventory.
Efficacies of the three randomness validity scales for the Jesness Inventory were investigated: the Jesness Variable Response Inconsistency scale (J-VRIN), the Variable Response scale (VR), and the Randomness scale (RD). Effectiveness was assessed by comparing the protocols of 93 male and 45 female delinquents ages 14 to 18 years screened for probable randomness, with a matched-pair MMPI-Adolescent with 500 computer-generated all- and half-random protocols. With the all-random set, for specificities of .90 or higher, scales showed sensitivities as high as .95 (VR), .90 (J-VRIN), and .14 (RD). With the half-random protocol, set sensitivities were .74 (VR), .70 (J-VRIN), and .07 (RD). Predictive power and overall effectiveness are reported for base rates of .20, .10, .067, and .05.
