“…Hillege, Das, and de Ruiter (2010) also reported that scores on the Dutch version of the YPI were related to self-reported adolescent substance abuse. Most recently, Colins, Andershed, and Pardini (2015) reported that the YPI was predictive of relational aggression, but not official or self-reported crime, using data from the Pittsburgh Youth Study. In terms of convergent validity, various research findings (e.g., Ansel, Barry, Gillen, & Herrington, 2014;Campbell, Doucette, & French, 2009) indicate that the YPI correlates with other measures of psychopathy, such as the Psychopathic Personality Inventory-Revised (PPI-R; Lilienfeld & Widows, 2005) and the Antisocial Process Screening Device (APSD; Frick & Hare, 2001).…”
