“…It should be stressed that while we can easily distinguish between diagnostic and statistical uses—because they are generally based on separate sciences and serve different application purposes—anecdotal evidence and field studies show that psychopathy assessments are commonly used for both purposes. For instance, once a person undergoes a PCL-R assessment, the outcome is interpreted by practitioners both as a diagnostic measure of psychopathy and as a statistical inference to predict relevant behaviors such as institutional misconduct, criminal recidivism, parole violation, and rehabilitation (e.g., Archer et al, 2006; DeMatteo et al, 2014; Hill & Demetrioff, 2019; Hurducas et al, 2014; Jonnson & Viljoen, 2021; Viljoen, McLachlan, et al, 2010). This sort of dual-type usage is also recommended by psychopathy assessment developers and researchers.…”
