Evaluación psicométrica de la psicopatía: una revisión metaanalítica

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 anti-social 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 anti-social 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.
