A Variable‐Response Scale (VR) was developed for detecting randomness in the Jesness Inventory. Item pairs addressing similar content areas were identified. Pairs which showed endorsement frequencies of 5% or less in the scale development sample (250 males, 250 females) were included. Effectiveness was assessed by comparing 250 all‐random and 250 part‐random computer‐generated protocols with those of honest subjects from a sample of 293 male delinquents classified as honest or not honest based on a matched‐pair MMPI‐A. VR was found to be very effective. Sensitivity, specificity, and other statistics were reported. Race differences were significant but very small. Younger children showed more inconsistency than older children. Age‐based modified t ‐score norms were developed (1138 male, 358 female delinquents, ages 13–18). © 1997 John Wiley & Sons, Inc.
