  • identifying careless responding with the psychopathic Personality Inventory revised validity scales
    Assessment, 2018
    Co-Authors: David K Marcus, Abere Sawaqdeh Church, Debra Oconnell, Scott O. Lilienfeld
    Abstract:

    The Psychopathic Personality Inventory-Revised (PPI-R) includes validity scales that assess Deviant Responding (DR), Virtuous Responding, and Inconsistent Responding. We examined the utility of these scales for identifying careless responding using data from two online studies that examined correlates of psychopathy in college students (Sample 1: N = 583; Sample 2: N = 454). Compared with those below the cut scores, those above the cut on the DR scale yielded consistently lower validity coefficients when PPI-R scores were correlated with corresponding scales from the Triarchic Psychopathy Measure. The other three PPI-R validity scales yielded weaker and less consistent results. Participants who completed the studies in an inordinately brief amount of time scored significantly higher on the DR and Virtuous Responding scales than other participants. Based on the findings from the current studies, researchers collecting PPI-R data online should consider identifying and perhaps screening out respondents with elevated scores on the DR scale.

  • examining the correlates of the coldheartedness factor of the psychopathic Personality Inventory revised
    Psychological Assessment, 2015
    Co-Authors: Joanna M Berg, Robert D Latzman, Lisa K Hecht, Scott O. Lilienfeld
    Abstract:

    Coldheartedness is a subscale of the Psychopathic Personality Inventory–Revised (PPI-R) that does not load onto either of the PPI-R’s two traditional higher order factors (Fearless Dominance [FD] and Self-Centered Impulsivity [SCI]). As a result, it has been omitted from analyses in many studies. However, owing to Coldheartedness’s associations with lack of empathy, guilt, and deep-seated social emotions, this subscale may be highly relevant to the construct of psychopathy. In a sample of 1,158 undergraduates, we attempted to clarify Coldheartedness’s correlates within the context of a nomological network of psychopathology and Personality; in addition, we examined Coldheartedness’s contributions to psychopathy above and beyond FD and SCI. Coldheartedness demonstrated negative correlations with the Big Five Personality factors, mixed correlations with indices of impulsivity, and largely negative correlations with measures of depression and anxiety. Regressions suggested that Coldheartedness displays substantial overlap with both FD and SCI but also contains psychologically important unique variance. Although the nature of this variance requires clarification, further research and perhaps an expansion of the Coldheartedness subscale may move the field toward a clearer understanding of the construct assessed by this measure.

  • using a genetic algorithm to abbreviate the psychopathic Personality Inventory revised ppi r
    Psychological Assessment, 2015
    Co-Authors: Hedwig Eisenbarth, Scott O. Lilienfeld, Tal Yarkoni
    Abstract:

    Some self-report measures of Personality and Personality disorders, including the widely used Psychopathic Personality Inventory–Revised (PPI-R), are lengthy and time-intensive. In recent work, we introduced an automated genetic algorithm (GA)-based method for abbreviating psychometric measures. In Study 1, we used this approach to generate a short (40-item) version of the PPI-R using 3 large-N German student samples (total N = 1,590). The abbreviated measure displayed high convergent correlations with the original PPI-R, and outperformed an alternative measure constructed using a conventional approach. Study 2 tested the convergent and discriminant validity of this short version in a fourth student sample (N = 206) using sensation-seeking and sensitivity to reward and punishment scales, again demonstrating similar convergent and discriminant validity for the PPI-R-40 compared with the full version. In a fifth community sample of North American participants acquired using Amazon Mechanical Turk, the PPI-R-40 showed similarly high convergent correlations, demonstrating stability across language, culture, and data-collection method. Taken together, these studies suggest that the GA approach is a viable method for abbreviating measures of psychopathy, and perhaps Personality measures in general.

  • development and validation of triarchic construct scales from the psychopathic Personality Inventory
    Psychological Assessment, 2014
    Co-Authors: Jason R Hall, Scott O. Lilienfeld, Christopher J Patrick, Laura E Drislane, Mario Morano, Norman G Poythress
    Abstract:

    The Triarchic model of psychopathy describes this complex condition in terms of distinct phenotypic components of boldness, meanness, and disinhibition. Brief self-report scales designed specifically to index these psychopathy facets have thus far demonstrated promising construct validity. The present study sought to develop and validate scales for assessing facets of the Triarchic model using items from a well-validated existing measure of psychopathy-the Psychopathic Personality Inventory (PPI). A consensus-rating approach was used to identify PPI items relevant to each Triarchic facet, and the convergent and discriminant validity of the resulting PPI-based Triarchic scales were evaluated in relation to multiple criterion variables (i.e., other psychopathy inventories, antisocial Personality disorder features, Personality traits, psychosocial functioning) in offender and nonoffender samples. The PPI-based Triarchic scales showed good internal consistency and related to criterion variables in ways consistent with predictions based on the Triarchic model. Findings are discussed in terms of implications for conceptualization and assessment of psychopathy.

  • Screening for Psychopathy: Validation of the Psychopathic Personality Inventory-Short Form with Reference Scores
    Journal of Psychopathology and Behavioral Assessment, 2013
    Co-Authors: Franca Tonnaer, Maaike Cima, Klaas Sijtsma, Kasia Uzieblo, Scott O. Lilienfeld
    Abstract:

    The current study reports validation results for the Psychopathic Personality Inventory (PPI) and its subscales, and for a newly developed PPI-Short Form (PPI-SF) in forensic and non-forensic populations. We also provide criterion reference scores for the PPI and the PPI-SF. In Study 1, we used PPI data from 1,065 participants and supplementary PCL-R data from a subsample of 91 forensic offenders. Mokken scale analysis was used to construct the PPI-SF. In Study 2, PPI-SF and PCL-R data were collected from 60 participants. The study yielded promising but preliminary support for the construct validity of the PPI and the PPI-SF. The PPI-SF is of interest for risk assessment because of its (a) strong relationship with the PCL-R total score and (b) subscales known for their predictive value for violence and criminal recidivism.

  • the Personality Inventory for icd 11 investigating reliability structural and concurrent validity and method variance
    Psychological Assessment, 2020
    Co-Authors: Michael Carnovale, Martin Sellbom, Michael R Bagby
    Abstract:

    The 11th edition of the International Classification of Diseases and Related Health Problems (ICD-11), recently approved by the World Health Organization, contains a new diagnostic approach for Personality disorders. This approach partly involves the consideration of 5 dimensional trait domain qualifiers-Negative Affectivity, Detachment, Dissocial, Disinhibition, and Anankastia. Oltmanns and Widiger (2018) recently developed a self-report measure, the Personality Inventory for ICD-11 (PiCD), to assess the 5 domains; however, further examination of the psychometric properties of the PiCD is warranted due to its limited research base. The present study aimed to further examine the reliability, structural and concurrent validity, and method variance of the PiCD in an ethnically diverse undergraduate sample (N = 518), who were also administered the Minnesota Multiphasic Personality Inventory-2-Restructured Form. First, results suggested that the PiCD domain scales exhibited adequate internal consistency reliability via coefficient categorical omega (range = .77-.87). Next, exploratory structural equation modeling results suggested support for a 4-factor solution, with the 4th factor thought to represent a bipolar continuum of Anankastia to Disinhibition severity. Random-intercept factor analysis results suggested a small amount of variance in items (4.88%) attributable to idiosyncratic scale usage. Lastly, relations between PiCD domains and Minnesota Multiphasic Personality Inventory-2-Restructured Form scales (Personality Psychopathology-5 and Higher Order scales) provided support for the validity of the Negative Affectivity, Detachment, and Dissocial domains, though relatively less support for the Disinhibition and Anankastia domains. Further examination of other psychometric properties and the nomological network of the PiCD is recommended. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

  • development and validation of an overreporting scale for the Personality Inventory for dsm 5 pid 5
    Psychological Assessment, 2017
    Co-Authors: Martin Sellbom, Sonya Dhillon, Michael R Bagby
    Abstract:

    Our aim in the current study was to develop a validity scale for the Personality Inventory for DSM-5 (PID-5) to detect noncredible overreported responding. To this end, we used a rare symptoms approach and identified extreme response options on PID-5 items that were infrequently endorsed by students in 3 different university samples (N = 1,370) and in a psychiatric patient sample (N = 194). The resulting 10-item scale (the PID-5-ORS) produced adequate-to-good estimates of internal reliability and was significantly correlated with the Minnesota Multiphasic Personality Inventory-2 Restructued Form (MMPI-2-RF) overreporting validity scales, providing evidence of concurrent validity. The criterion validity of the PID-5-ORS was demonstrated in an analog simulation design study. More specifically, university students instructed to overreport (n = 80) scored substantially higher on the PID-5-ORS relative to both a group of genuine psychiatric patients and students instructed to complete the PID-5 under standard (honest) instructions (n = 161); the effect size magnitudes associated with these differences were large. Classification accuracy analyses further revealed that high scores on the PID-5-ORS were associated with high specificity (and thus, low rates of false positive classifications) in differentiating overreporters from genuine patients, with sensitivity being somewhat weaker.

  • response bias and the Personality Inventory for dsm 5 contrasting self and informant report
    Personality Disorders: Theory Research and Treatment, 2017
    Co-Authors: Lena C Quilty, Nicole Cosentino, Michael R Bagby
    Abstract:

    Previous research has raised concerns that scores derived from the Personality Inventory for DSM-5 (PID-5; American Psychiatric Association, 2013; Krueger, Derringer, Markon, Watson, & Skodol, 2012) may be compromised by response styles such as underreporting or overreporting. The informant-report form of the PID-5 (PID-5-IRF; Markon, Quilty, Bagby, & Krueger, 2013) has been recommended for use when response bias is an assessment concern. The purpose of the current investigation was to evaluate PID-5 and PID-5-IRF scale score elevations across participants exhibiting signs of overreporting or underreporting. A total of 245 adults completed the PID-5 and the Revised NEO Personality Inventory (NEO PI-R; Costa & McCrae, 1992). A family member or friend of at least 1 year's acquaintance completed the PID-5-IRF for 216 of these. A total of 211 target-informant pairs were available for analysis. Participants were categorized as overreporting and underreporting according to NEO PI-R validity scale cutoffs. The majority of PID-5 scale scores were elevated in those identified as overreporting; more than half of the PID-5-IRF scale scores were similarly elevated. The majority of PID-5 scale scores were lower in those scoring above underreporting cut-offs; however, PID-5-IRF scales were not as consistently or strongly impacted. PID-5 scales were strongly impacted by response bias, whereas PID-5-IRF scores were less strongly impacted overall, and more so by overreporting bias. Caution when using these instruments in the assessment of Personality disorders prone to over- or underreporting may be warranted. (PsycINFO Database Record

  • evaluating the structure of psychopathic Personality traits a meta analysis of the psychopathic Personality Inventory
    Psychological Assessment, 2018
    Co-Authors: Jared R Ruchensky, John F Edens, Katherine S Corker, Brent M Donnellan, Edward A Witt, Daniel M Blonigen
    Abstract:

    Which core traits exemplify psychopathic Personality disorder is a hotly debated question within psychology, particularly regarding the role of ostensibly adaptive traits such as stress immunity, social potency, and fearlessness. Much of the research on the interrelationships among putatively adaptive and more maladaptive traits of psychopathy has focused on the factor structure of the Psychopathic Personality Inventory (PPI) and its revision, the Psychopathic Personality Inventory-Revised (PPI-R). These instruments include content scales that have coalesced to form 2 higher order factors in some (but not all) prior studies: Fearless Dominance and Self-Centered Impulsivity. Given the inconsistencies in prior research, we performed a meta-analytic factor analysis of the 8 content scales from these instruments (total N > 18,000) and found general support for these 2 dimensions in community samples. The structure among offender samples (e.g., prisoners, forensic patients) supported a 3-factor model in which the Fearlessness content scale loaded onto Self-Centered Impulsivity (rather than Fearless Dominance). There were also indications that the Stress Immunity content scale had different relations to the other PPI scales in offender versus community samples. We discuss the theoretical and diagnostic implications of these differing factor structures for the field of psychopathy research. (PsycINFO Database Record

  • the two factor model of psychopathic Personality evidence from the psychopathic Personality Inventory
    Personality Disorders: Theory Research and Treatment, 2013
    Co-Authors: David K Marcus, Jessica J Fulton, John F Edens
    Abstract:

    Psychopathy or psychopathic Personality disorder represents a constellation of traits characterized by superficial charm, egocentricity, irresponsibility, fearlessness, persistent violation of social norms, and a lack of empathy, guilt, and remorse. Factor analyses of the Psychopathic Personality Inventory (PPI)typically yield two factors: Fearless Dominance (FD) and Self-Centered Impulsivity (SCI). Additionally, the Coldheartedness (CH) subscale typically does not load on either factor. The current paper includes a meta-analysis of studies that have examined theoretically important correlates of the two PPI factors and CH. Results suggest that (a) FD and SCI are orthogonal or weakly correlated, (b) each factor predicts distinct (and sometimes opposite) correlates, and (c) the FD factor is not highly correlated with most other measures of psychopathy. This pattern of results raises important questions about the relation between FD and SCI and the role of FD in conceptualizations of psychopathy. Our findings also indicate the need for future studies using the two-factor model of the PPI to conduct moderational analyses to examine potential interactions between FD and SCI in the prediction of important criterion measures.

  • assessing the external correlates of alternative factor models of the psychopathic Personality Inventory short form across three samples
    Journal of Personality Assessment, 2011
    Co-Authors: Shannon Toney Smith, John F Edens, Michael G Vaughn
    Abstract:

    This study investigated various theoretically relevant correlates of a short form of the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) using archival data from large undergraduate, foster care, and juvenile offender samples. External correlates of the 2 primary scales (PPI-I and PPI-II) and the Coldheartedness subscale were for the most part consistent with prior findings. Analyses for an alternate factor model in which the Fearlessness subscale loaded onto PPI-II (rather than PPI-I) resulted in relatively few substantial changes to the pattern of correlations with criterion measures, but a third factor that included the Coldheartedness and Carefree Nonplanfulness subscales functioned differently than Coldheartedness alone in these data.

  • further evidence of the divergent correlates of the psychopathic Personality Inventory factors prediction of institutional misconduct among male prisoners
    Psychological Assessment, 2008
    Co-Authors: John F Edens, Scott O. Lilienfeld, Norman G Poythress, Christopher J Patrick, Amy Test
    Abstract:

    Recent evidence suggests that 2 largely orthogonal dimensions underpin the latent construct assessed by the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996): Fearless Dominance (PPI-I) and Impulsive Antisociality (PPI-II). Relatively few data exist on the correlates of these 2 dimensions in offender samples, however. The present study examines the criterion-related validity of these 2 dimensions among male prison inmates (N = 131) in relation to the prediction of 3 categories of institutional maladjustment: aggressive misconduct, nonaggressive misconduct, and any misconduct. PPI-II significantly predicted each criterion type, with effect sizes of moderate magnitude, whereas PPI-I was essentially unrelated to these outcome measures.

  • construct validity of the psychopathic Personality Inventory two factor model with offenders
    Psychological Assessment, 2006
    Co-Authors: Christopher J Patrick, Scott O. Lilienfeld, Norman G Poythress, John F Edens, Stephen D Benning
    Abstract:

    Much of the research on psychopathy has treated it as a unitary construct operationalized by total scores on one (or more) measures. More recent studies on the Psychopathic Personality Inventory (PPI) suggest the existence of two distinct facets of psychopathy with unique external correlates. Here, the authors report reanalyses of two offender data sets that included scores on the PPI along with various theoretically relevant criterion variables. Consistent with hypotheses, the two PPI factors showed convergent and discriminant relations with criterion measures, many of which would otherwise have been obscured when relying on PPI total scores. These results highlight the importance of examining facets of psychopathy as well as total scores.
