Background and objectives This study aimed to establish a clinical cut-off for the self-report Conscientiousness dimension of the Dimensional Clinical Personality Inventory 2 (IDCP-2) for people with Obsessive–compulsive personality disorder (OCPD) diagnosis. The following hypotheses were raised: (1) scale should be more reliable for assessing more pathological levels compared to milder levels of conscientiousness, and (2) items should be able to discriminate OCPD patients from other groups (i.e., non-patients and mental health patients).
Methods Participants were 2449 adults, among outpatients diagnosed with OCPD, outpatients diagnosed with other PDs, and adults from the community.
Results According to the Wright map, outpatients were located at the very high level on the latent continuum of the Conscientiousness dimension, with a larger effect size for the mean difference between OCPD patients and non-patients. The ROC curve indicated a cutoff at −.33 score in theta standardization, with 85% of sensitivity and 58% of specificity.
Conclusion Findings from this investigation suggest the IDCP-2 Conscientiousness dimension as useful for screening purposes of the core traits of the OCPD. Potential clinical applications for the scale and limitations from the present study are discussed.
