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.
"Several studies have examined the reliability of test scores and the validity of interpretations of these scores on this measure among noninstitutionalized populations of adults (primarily undergraduates ); however, the LSRP has not yet been examined among populations under age 18. Among undergraduate samples, the LSRP has demonstrated adequate internal consistency for both the total score and for the primary and secondary subscales, with moderate correlations between the subscales (Falkenbach et al., 2007; Lynam et al., 1999; Miller, Gaughan, & Pryor, 2008). Studies have provided support for this two-factor model among undergraduate samples, differentiating between primary and secondary psychopathy through both exploratory (Levenson et al., 1995) and confirmatory factor analyses (Lynam et al., 1999).

[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to assess the measurement invariance of 2 commonly used measures of youth psychopathic characteristics across sex and racial/ethnic groups. Among a community sample of Hispanic and Black adolescents (N = 355; 50.5% female; mean age = 15.09) and their parents, this study tested the configural and metric invariance of the Levenson Self-Report Psychopathy Scale (LSRP; Levenson, Fitzpatrick, & Kiehl, 1995) and the parent-report version of the Inventory of Callous-Unemotional Traits (Frick, 2004). Preliminary analyses indicated that the adolescents in the present study reported similar rates of psychopathic characteristics as those reported by other studies of adolescents and young adults. Results of the multigroup invariance analyses indicated that these measures are invariant across sex and between Hispanic and Black youth. In addition, further analyses assessing associations between these measures and a number of behavioral and emotional characteristics indicated that scores on the LSRP Scale and Callous-Unemotional Traits demonstrate good convergent and discriminant validity with few differences by sex or race/ethnicity. To date, research on psychopathy has focused predominantly on samples of White males. Therefore, it is important that research examines the equivalence of measures of psychopathic characteristics across different populations, so that accurate assessments can be made to inform intervention and treatment efforts.

"Les coefficients alpha obtenus dans les études canadiennes et américaines varient de 0,77 à 0,85 pour l'échelle totale, de 0,76 à 0,83 pour l'échelle de psychopathie primaire et de 0,59 à 0,69 pour l'échelle secondaire (Brinkley et al., 2001 ; Levenson et al., 1995 ; Savard et al., 2005, 2006). Les deux échelles du LSRP sont modérément corrélées (r = 0,43 à 0,46 ; Lynam et al., 1999 ; Miller et al., 2008) et significativement associées aux deux facteurs du PCL-R (Brinkley et al., 2001). Les deux échelles sont également corrélées à des mesures d'abus de substances et de criminalité. "
"Items were modeled after the PCL-R, evidence was found for correlated yet distinct primary and secondary factors, and convergent and predictive validity for the scales was further established (Levenson et al. 1995). Subsequent investigations have provided support for the LSRP in relation to model-based cluster analyses (Falkenbach et al. 2008), convergence with other self-report scales of psychopathy (Lynam et al. 2011), the ability to predict personality disorder symptoms and traits (Miller et al. 2008), and sensitivity to dimensional rather than taxonomic features of psychopathy (Walters et al. 2008). "
[Show abstract][Hide abstract] ABSTRACT: A review of the literature suggests that higher levels of psychopathy may be linked to less effective behavioral control. However, several commentators have urged caution in making statements of this type in the absence of direct evidence. In two studies (total N = 142), moment-to-moment accuracy in a motor control task was examined as a function of dimensional variations in psychopathy in an undergraduate population. As hypothesized, motor control was distinctively worse at higher levels of psychopathy relative to lower levels, both as a function of primary and secondary psychopathy and particularly their shared variance. These novel findings provide support for the idea that motor control systematically varies by psychopathy, in a basic manner, consistent with views of psychopathy emphasizing lesser control.
