Development of an indicator for screening the dependent personality disorder using factors of the Dimensional Clinical Personality Inventory 2 in a Brazilian community sample

Abstract

We aimed to verify the capacity of the Dimensional Clinical Personality Inventory 2 (IDCP-2) factors to identify people with high levels of dependent personality disorder (DPD) traits in a Brazilian sample extracted from the general population. Participants were 1469 adults who responded to factors from the IDCP-2, the Personality Inventory for DSM-5 (PID-5), and the Structured Clinical Interview for the DSM-IV—Personality Questionnaire (PQ-SCID-II). We found three profiles via Latent Profile Analysis using PID-5 facets. Based on the discrimination capacity of IDCP-2 factors to identify these profiles, we created a DPD score for screening patients showing high levels of DPD traits. The IDCP-2 factors were discriminative of the profiles, showing large effects, except Perseveration. The DPD score presented a cutoff equal to 23 with good discriminative indicators, prioritizing the ability to produce fewer false negatives, and higher than those observed in the PQ-SCID-II. The DPD score can be clinically employed to indicate patients presenting a profile matching the DPD pattern. Moreover, the DPD score can assist the professional in mapping the patient’s pathological profile into typical DPD traits, as well as helping to plan more personalized interventions. Studies focusing on clinical samples must be conducted to investigate whether our findings replicate.
