The Deenz Psychopathy Spectrum Scale (DPSS-24) is a newly developed psychometric instrument aimed at assessing psychopathy traits across diverse adult populations. This study presents preliminary data collected from two distinct samples—a group of 21 participants from an initial testing phase and a German sample of 31 participants. Each participant completed the DPSS-24, a 24-item scale designed to measure various psychopathy-related behaviors, including impulsivity, emotional detachment, and interpersonal difficulties, using a Likert scale ranging from 1 to 5.
