The Minnesota Multiphasic Personality Inventory–Second Edition includes a new validity scale, the VRIN scale, intended to detect random responding. High scores are viewed as casting suspicion on the validity of the profile. For the present study, the authors evaluated some of the complexities of the VRIN scale including its interaction with the F scale. In particular, we tested two hypotheses. First is that among psychotically disturbed test takers, some inconsistent responding is an integral and expected mode of responding to a self-report measure. That is, in an inpatient psychiatric population increased confused responding (high VRIN score) is related in predictable ways to increased endorsement of pychotic scales and two-point codes and to increased psychotic diagnoses. The second hypothesis is a corollary—that the absence of inconsistency (low VRIN) in a protocol indicating acute distress (high F) may indicate that a respondent is being too consistent in presenting self as having severe difficulties. In this case, the rest of the protocol may be an exaggerated description of the clinical presentation. A sample of 521 psychiatric inpatients was used to evaluate these hypotheses. Some support for both hypotheses is reported. Further studies are recommended to evaluate the hypotheses.

The Youth Psychopathic Traits Inventory (YPI) is widely used in research, but there currently exist no means to identify potentially invalid protocols resulting from careless or random responding. We describe the development of an inconsistent responding scale for the YPI using three archival samples of youths, including two from the United States (juvenile justice and middle school) and one from Germany (vocational training school). We first identified pairs of correlated YPI items and then created a total score based on the sum of the absolute value of the differences for each item pair. The resulting scale strongly differentiated between genuine protocols and randomly generated YPI data (n = 1,000) across samples (AUC values = .88−.92). It also differentiated between genuine protocols and those same protocols after 50% of the original YPI items were replaced with random data (AUCs = .77−.84). Scores on this scale also demonstrated fairly consistent patterns of association with theoretically relevant correlates.

The current study aimed to examine the effects of inconsistent responding on Psychopathic Personality Inventory–Revised (PPI-R; Lilienfeld & Widows, 2005) scale scores and the utility of the IR scale in detecting such responding in a correctional setting. The study employed an internally controlled method of simulating inconsistent responding by inserting ascending levels of computer-generated random responses into PPI-R protocols. Participants were 218 male inmates from a medium-security prison in central Kentucky in the United States. Results indicated that psychometric properties of PPI-R scores were substantially attenuated at as low as 40% of random responding. Additionally, results indicated that an Inconsistent Responding (IR) Scale cut-off of 40 would provide the best balance between sensitivity and specificity in detecting invalid PPI-R protocols. Overall, this study highlighted the utility of the IR Scale in self-report psychopathy measures and the need to consider such response biases in research and clinical settings.
