Development of the Dimensional Clinical Personality Inventory – Avoidant version based on the HiTOP

This study aimed to develop a specific version of the Dimensional Clinical Personality Inventory 2 (IDCP-2), focused on the assessment of avoidant personality disorder (AvPD) according to the Hierarchical Taxonomy of Psychopathology (HiTOP). First, we developed the IDCP-Av, composed of one new factor and four factors from the IDCP-2. A total of 436 adults completed this, and two external measures (PID-5 and FFAvA). The IDCP-Av factors and its total score presented high reliability. Correlations and group comparisons were coherent, corroborating expectations. Favorable evidence was observed for the use of the IDCP-Av for the measurement of AvPD, although future studies should replicate the findings in samples composed of patients.
