Dimensional literature reinforces the relevance of specific Dependent personality disorder (DPD) traits, as submissiveness, insecurity and avoidance of abandonment. In this paper we measured these traits through the Dimensional Clinical Personality Inventory-2 (IDCP-2). This study aims to verify the capacity of IDCP-2 factors to discriminate and predict DPD related symptoms. From a dataset with 4,503, a total of 305 people was divided in three groups: the community group (n = 200), the non-DPD group (N = 84), and the DPD group (n = 21). We administered six factors from IDCP-2, Insecurity, Abandonment Avoidance, Self-devaluation, Submissiveness, Masochism, and Self-driven Hopelessness. Groups comparison were significant, showing high effects in mostly cases. Multiple regression analysis showed the best predictors of the groups, i.e. Abandonment Avoidance and Self-driven Hopelessness. The findings of this study demonstrate that IDCP-2 covers the core traits of DPD, therefore, being a valid and applicable measure to discriminate DPD, which is particularly relevant in clinical settings. Although our findings suggested two factors as the most relevant measures to discriminant DPD patients from non-DPD/community samples, we did not suggest the restrict use of the Abandonment Avoidance and Self-driven Hopelessness factors for DPD screening. Limitations of the study were discussed.
