SALVADOR, Benjamín; ARCE, Ramón; RODRIGUEZ-DIAZ, Francisco J.  and  SEIJO, Dolores. Psychometric assessment of psychopathy: A meta-analytical review. rev.latinoam.psicol. [online]. 2017, vol.49, n.1, pp.36-47. ISSN 0120-0534.  https://doi.org/10.1016/j.rlp.2015.09.015.

Most of the literature on psychopathy is focused on its measurement. There are four reference tools used to assess psychopathy: the Psychopathy Checklist (PCL), the Levenson's Primary and Secondary Psychopathy Scales (LPSP), the Self-Report Psychopathy Scale (SRP), and the Psychopathic Personality Inventory (PPI). In order to do this, a psychometric correlational meta-analysis was designed to test the convergent validity between these tools on the psychopathy dimension and the two common factors among them: the affective and antisocial deviation factors. The results showed a positive, significant and generalisable convergent validity between tools, in the psychopathy dimension, as well as in the affective and antisocial factors. Moreover, the results also showed that the PCL was the most appropriate tool to measure psychopathy in clinical samples, and the PPI was so in sub-clinical cases.

Keywords : Meta-analysis; Assessment; Psychopathy; Convergent validity; Empirical redundancy; Conceptual homogeneity.
