CARVALHO, Lucas de Francisco; SALVADOR, Ana Paula  and  GONCALVES, André Pereira. Development and Preliminary Psychometric Evaluation of the Dimensional Clinical Personality Inventory - Schizoid Personality Disorder Scale. Aval. psicol. [online]. 2020, vol.19, n.3, pp. 289-297.

A new dimensional-based framework was proposed, the Hierarchical Taxonomy of Psychopathology (HiTOP). This study aimed to develop a specific version of the Dimensional Clinical Personality Inventory 2 (IDCP-2), focused on the assessment of the schizoid personality disorder (SZPD) according to the HiTOP. In stage 1, we developed a new factor to cover all SZPD traits, as presented in the HiTOP. Six factors (one new and five from the IDCP-2) composed the IDCP-SZPD. In stage 2, 434 adults from the community, aged from 18 to 67 years (M=31.6, SD=9.7), completed factors from three self-report measures: the IDCP-SZPD, PID-5, and FFaVA. The IDCP-SZPD factors and total score presented high reliability. Correlations and a bootstrap two-sample t-test comparison corroborated the expectations. Although we found evidence supporting the use of the IDCP-SZPD for the measurement of SZPD traits, further research is needed to verify the replicability of the present findings in samples composed of SZPD patients.
