“…Primary and secondary psychopathy scores demonstrated sufficient internal consistency and substantial between-subject variability ( Table 3). The range of primary and secondary psychopathy scores obtained in the present sample (Table 3) was consistent with previous studies that had similar sample demographics (Prado, Treeby, & Crowe, 2015;Tsang, Salekin, Coffey, & Cox, 2017).…”

Psychopathic traits predispose individuals toward antisocial behavior. Such antagonistic acts often result in “unsuccessful” outcomes such as incarceration. What mechanisms allow some people with relatively high levels of psychopathic traits to live “successful”, unincarcerated lives, in spite of their antisocial tendencies? Using neuroimaging, we investigated the possibility that “successful” psychopathic individuals exhibited greater development of neural structures that promote “successful” self-regulation, focusing on the ventrolateral prefrontal cortex (VLPFC). Across two structural magnetic resonance imaging studies of “successful” participants (Study 1: N = 80 individuals in long-term romantic relationships; Study 2: N = 64 undergraduates), we observed that gray matter density in the left and right VLPFC was positively associated with psychopathic traits. These preliminary results support a compensatory model of psychopathy, in which “successful” psychopathic individuals develop inhibitory mechanisms to compensate for their antisocial tendencies. Traditional models of psychopathy that emphasize deficits may be aided by such compensatory models that identify surfeits in neural and psychological processes.

Psychopathic traits predispose individuals toward antisocial behavior. Such antagonistic acts often result in ‘unsuccessful’ outcomes such as incarceration. What mechanisms allow some people with relatively high levels of psychopathic traits to live ‘successful’, un-incarcerated lives, in spite of their antisocial tendencies? Using neuroimaging, we investigated the possibility that ‘successful’ psychopathic individuals exhibited greater development of neural structures that promote ‘successful’ self-regulation, focusing on the ventrolateral prefrontal cortex (VLPFC). Across two structural MRI studies of ‘successful’ participants (Study 1: N = 80 individuals in long-term romantic relationships; Study 2: N = 64 undergraduates), we observed that gray matter density in the left and right VLPFC was positively associated with psychopathic traits. These preliminary results support a compensatory model of psychopathy, in which ‘successful’ psychopathic individuals develop inhibitory mechanisms to compensate for their antisocial tendencies. Traditional models of psychopathy that emphasize deficits may be aided by such compensatory models that identify surfeits in neural and psychological processes.

“…Specifically, Levenson et al (1995) formulated three main hypotheses, which were supported by the data: first, that psychopathy scores would be related to antisocial behavior; second, that psychopathy scores would not be related to indexes of fearlessness or adventurousness; and third, that state anxiety would be positively related to secondary psychopathy, but unrelated to primary psychopathy. In more recent studies, the LSRP scales have shown adequate construct validity, as expected for scales aligned to the two factors of the PCL (Miller, Gaughan, & Pryor, 2008;Salekin, Chen, Sellbom, Lester, & MacDougall, 2014;Tsang, Salekin, Coffey, & Cox, 2017).…”

The Levenson Self-Report Psychopathy (LSRP) scale is widely used to assess psychopathic traits in noninstitutionalized samples. Recent studies suggest that a three-factor structure measuring Egocentricity, Callousness, and Antisocial factors outperformed the original two-factor structure of the LSRP. This study replicated and extended these findings by examining the factor structure and construct validity of a Dutch version of the LSRP in a community sample (N ¼ 856, subsamples ranging between 140 and 572 participants). Confirmatory factor analysis results corroborated the superiority of the three-factor model of the LSRP, using 19 of the 26 LSRP items. Limitations included the need to specify correlated residuals for some indicators, although these were largely in line with prior studies. Across three subsamples, we found evidence for construct validity of the LSRP subscales. Egocentricity and Antisocial showed a pattern of differential associations with external correlates in accordance with theoretical expectations. Callousness shared some correlates with Egocentricity, others with Antisocial, and uniquely predicted low morality and high physical aggression. Few exceptions to the hypothesized associations were observed, mostly concerning Callousness. Overall, the LSRP three-factor model received further support in a Dutch sample, and is thus recommended in future research, possibly adding items to improve the performance of the Callousness factor.
