Abstract
We aimed to develop a version of the Dimensional Clinical Personality Inventory 2 (IDCP-2) according to the Hierarchical Taxonomy of Psychopathology (HiTOP) for the assessment of antisocial personality disorder traits (i.e., IDCP Antisocial Personality Disorder Scale; IDCP-ASPD), as well as verify its psychometric properties. We developed new factors to cover ASPD traits, and collect data with 206 adults from the community (Mage = 31.3; 77.8% women). Participants completed the IDCP-ASPD, factors from IDCP-2, and Personality Inventory for DSM-5 (PID-5). Exploratory structural equation modeling (E-SEM) suggested a 3 factors solution, grouping the 14 factors composing the IDCP-ASPD. Reliability indicators were good. Correlations between IDCP-ASPD and external measures corroborated expectations. The bootstrap two-sample t-test comparing non-clinical and psychiatric groups suggested good discrimination capacity of the IDCP-ASPD. Favorable evidence was found for the usability of the developed scale for ASPD traits measurement, although future studies must replicate the findings in samples composed by ASPD patients.

Resumen: Nuestro objectivo fue desarollar una version del Inventário Dimensional Clínico da Personalidade 2 (IDCP-2) que se basó en Hierarchical Taxonomy of Psychopathology (HiTOP) para evaluar rasgos del transtorno de personalidad antisocial (i.e., IDCP escala Antissocial; IDCP-Antisocial personality disorder (ASPD)), y verificar sus propriedades psicometricas
Step 1 – IDCP-2 revision procedures according to pathological traits from spectra of the HiTOP model In Table 1 the spectra from HiTOP related to the ASPD are presented, as well the respective traits, and the typical traits of the ASPD
ASPD traits are present in the general population, and their extreme manifestation can cause impairments in various areas of everyday life (Robins et al, 1991; Wallace et al, 2009)

Findings suggest men presenting three more times this disorder than women (Derefinko & Widiger, 2016; Glenn et al, 2013) In forensic samples, these values increase to approximately 50% in men (Coid & Ullrich, 2010; Fazel & Danesh, 2002), and 31.8% in women (Coid & Ullrich, 2010). In a review of epidemiological data (Robins, Tipp, & Pryzbeck, 1991), 47% of people filled in criteria for ASPD according to the DSM-III. These individuals presented successive prison records, and difficulties as workplace problems, violence, traffic offenses, and severe marital problems. Studies suggest that ASPD (Marcus, Lilienfeld, Edens, & Poythress, 2006; Walters, 2008) and psychopathologies in general (Wright et al., 2013), should be understood under a dimensional nature
