Using Pathological Traits for the Assessment of Suicide Risk: A Suicide Indicator Proposal for the Dimensional Clinical Personality Inventory 2

Abstract

This study aimed to investigate the discriminative capacity of idcp-2 factors to identify people with suicide risk. Moreover, we are providing a suicide indicator for idcp-2. Participated 346 people aged between 18 and 72 years who responded to asiq, idcp-2, and pid-5. We divided participants into three groups: low-risk group, moderate-risk, and high-risk group. We conducted mean comparisons, linear regression analysis, and roc curve verification. The idcp-2 factors were able to discriminate between the groups, with the high-risk presenting the highest means. The regression indicated Self-devaluation and Hopelessness as variables with a significant single contribution in explaining suicidal behavior. Suicide risk indicators demonstrated adequate performance in identifying people according to the risk group. Our findings indicate that the idcp-2 factors can discriminate groups of people according to suicidal behavior. Besides, the suicide indicator developed showed sensitivity in the identification of people who reported attempted suicide.
