This is a cross‐sectional study investigating the validity of the Dimensional Clinical Personality Inventory 2 (IDCP‐2) as a tool for assessing HiTOP spectra. In Study 1, a nonclinical sample of 1659 Brazilian participants (65.4% females, with ages ranging from 18 to 70 years) was utilized to evaluate the internal structure of the IDCP‐2 and its alignment with the HiTOP framework, according to four experts' independent ratings. Given the disparities in expert ratings regarding the conscientiousness scales of IDCP‐2, we conducted exploratory structural equation modeling (ESEM) to identify the optimal placement for the anankastia factor within our model. Study 2 involved 641 nonclinical participants (87.17% females, with ages ranging from 18 to 82 years) and examined the external validity of the IDCP‐2 factors that are shown to be representative of the HiTOP spectra by correlating its scales with the PID5BF + M domains. The findings indicate the IDCP‐2's robust internal consistency and factorial validity as a tool for assessing the HiTOP spectra and confirming its external validity based on the significant moderate to high correlations with the PID5BF + M domain. Additionally, our results suggest anankastia to be a separate sixth factor within the HiTOP framework. These results underscore the IDCP‐2's value in capturing a wide range of pathological traits, contributing to a more nuanced understanding of personality and psychopathology. Future research should focus on further validating the IDCP‐2 in clinically diverse populations, to enhance its clinical applicability according to global healthcare developments, and to support the broader implementation of the HiTOP model globally
