Comparing Two Alternative Measures of General Personality in the Assessment of Psychopathy: A Test of the NEO PI‐R and the MPQ

This study examined the interrelations between two measures of personality, the Revised NEO Personality Inventory (NEO PI-R; P. T. Costa & R. R. McCrae, 1992) and the Multidimensional Personality Questionnaire (MPQ; Tellegen & Waller, 2008), and their relations with psychopathy in a sample of undergraduates. Results revealed good convergence between conceptually related personality traits; however, the NEO PI-R facets accounted for more variance in the MPQ subscales (mean R(2)=.49) than did MPQ subscales in NEO PI-R facets (mean R(2)=.35). Both accounted for substantial proportions of variance in psychopathy scores, although the NEO PI-R accounted for larger proportions and manifested greater incremental validity when using the broader domains of each measure; the differences decreased when the narrower facets/subscales were used. The results suggest that, although both measures assess psychopathy-related traits, the NEO PI-R provides a more complete description because of its assessment of interpersonal antagonism and the central role of this construct in psychopathy.

The Levenson Self-Report Psychopathy Scale: An Examination of the Personality Traits and Disorders Associated With the LSRP Factors

There are several self-report measures of psychopathy, most of which use a two-factor structure. There is debate regarding the convergence of these factors, particularly with regard to Factor 1 (F1), which is related to the interpersonal and affective aspects of psychopathy; Factor 2 (F2) is related to the social deviance associated with psychopathy. This study examines the relations between the Levenson Self-Report Psychopathy (LSRP) factors and personality traits and disorders (PDs) in an undergraduate sample (n = 271). LSRP Factor 1 is related to an antagonistic interpersonal style (i.e., low Agreeableness; high Narcissistic PD and ratings of prototypical psychopathy), whereas Factor 2 is more strongly related to negative emotionality (i.e., Neuroticism), disinhibition (i.e., low Conscientiousness) and a broad array of PD symptoms. The authors interpret these findings in the context of alternative measures of psychopathy and suggest that the LSRP is a reasonable, albeit imperfect, measure of psychopathy.

A Comparison of the Psychological Entitlement Scale and the Narcissistic Personality Inventory's Entitlement Scale: Relations With General Personality Traits and Personality Disorders

Given the negative consequences of psychological entitlement, it is important to have a reliable and valid measure of the construct. We used an undergraduate sample (N = 271) to examine the Entitlement subscale (ENT) of the Narcissistic Personality Inventory (Raskin & Terry, 1988) and the Psychological Entitlement Scale (PES; Campbell, Bonacci, Shelton, Exline, & Bushman, 2004) in relation to general personality traits (i.e., Revised NEO Personality Inventory; Costa & McCrae, 1992) and personality disorders (PDs; Personality Diagnostic Questionnaire–4; Hyler, 1994). We found similar personality correlates (e.g., disagreeableness; Cluster B PDs) for both measures, although ENT was comprised of greater disagreeableness and less warmth and positive affect. ENT was also more positively associated with schizoid and borderline PDs compared to the PES. Overall, these measures are closely related with regard to their relations with general and pathological personality dimensions, although the ENT scale may capture a slightly more pathological variant.

TESTING TWO ALTERNATIVE PATHOLOGICAL PERSONALITY MEASURES IN THE ASSESSMENT OF PSYCHOPATHY: AN EXAMINATION OF THE SNAP AND DAPP-BQ

The current study examined the interrelations between two measures of pathological personality, the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1993) and the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ; Livesley, 1990), and their respective relations with psychopathy. Two hundred and twenty-nine undergraduate students completed the SNAP, DAPP-BQ, and two self-report psychopathy inventories, the Levenson Self-Report Psychopathy Scale (LSRP; Levenson, Kiehl, & Fitzpatrick, 1995) and the Psychopathic Personality Inventory-Revised (PPI-R; Lilienfeld & Widows, 2005). Results revealed good convergence between conceptually related SNAP and DAPP-BQ subscales. Both the SNAP and DAPP-BQ accounted for a substantial amount of variance in psychopathy scores although the DAPP-BQ accounted for a larger percentage of the variance and demonstrated greater incremental validity. Results suggest that both measures can be successfully used to assess traits associated with psychopathy.

Affective lability: Separable from neuroticism and the other big four?

The goals of the current study were to use specific measures of affective lability and neuroticism to examine the nomological network surrounding both constructs and to test the degree to which a measure of general personality can account for variability in affective lability. Using a psychiatric outpatient sample (n=48), we assessed personality disorder (PD) symptoms, personality, and level of functioning across a range of domains. Neuroticism and affective lability demonstrated a small but significant positive correlation and manifested a divergent pattern of correlations with PDs and measures of functioning. Specifically, neuroticism was correlated primarily with Borderline, Avoidant and Dependent PDs, whereas affective lability was primarily correlated with Cluster B PDs. In addition, neuroticism evinced significant correlations with a range of functional impairments, whereas affective lability was correlated only with self-harm. Regression analyses demonstrated that a substantial portion of the variance in affective lability scales can be explained by Five-Factor Model domains, particularly if the narrower facets are used. The current findings suggest that neuroticism and affective lability are related but in a complex manner that involves other basic personality domains in addition to neuroticism.

The Consequences of Depressive Affect on Functioning in Relation to Cluster B Personality Disorder Features

The authors examined the effects of depressed affect (DA) on functioning measured by behavioral tasks pertaining to abstract reasoning, social functioning, and delay of gratification in relation to Cluster B personality disorder features (PDs) in a clinical sample. Individuals were randomly assigned to either a DA induction or control condition. Consistent with clinical conceptualizations, the authors expected that Cluster B PD symptoms would be related to maladaptive responding (e.g., poorer delay of gratification) when experiencing DA. As hypothesized, many of the relations between the Cluster B PDs and functioning were moderated by DA (e.g., borderline PD was negatively related to abstract reasoning, but only in the DA condition). However, many of the Cluster B PDs symptom counts were related to more adaptive responses in the DA condition (e.g., less aggressive social functioning, better delay of gratification). The authors speculate that individuals with Cluster B PDs may be more likely to respond maladaptively to alternative negative mood states, such as anger and fear.
