Paranoia and risk of personality disorder in the general population Muñoz-Negro, José Eduardo Gutiérrez, Blanca Cervilla, Jorge A. BACKGROUND: We hypothesized that paranoia is associated with personality disorder (PD) in the general population. METHOD: This was a population-based cross-sectional survey carried out in Andalusia (Spain) using a representative sample of 4 507 participants. Paranoia was measured using the Green Paranoid Thought Scale, and risk of having a PD was screened using the Standardized Assessment of Personality Abbreviated Scale whilst borderline personality disorder (BPD) was measured with the CEPER-III Exploratory Interview of Personality disorder. Adjusted Pearsons' correlations between paranoia and PD or BPD were calculated. RESULTS: Paranoia was associated with the risk of having PD and, more robustly, with BPD. Both associations held true for both personality outcomes (PD and BPD) when tested for two Green Paranoid Thought Scale paranoia subtypes (persecutory and reference) after accounting for the effects of age, sex and child abuse. CONCLUSIONS: Paranoia seems to either augment the risk for, or be part of, PD/BPD. 2025-01-24T10:56:31Z 2025-01-24T10:56:31Z 2019-05 journal article Personal Ment Health. 2019 May;13(2):107-116 https://hdl.handle.net/10481/100247 10.1002/pmh.1443 eng http://creativecommons.org/licenses/by-nc-nd/3.0/ open access Creative Commons Attribution-NonCommercial-NoDerivs 3.0 License John Wiley & Sons, Ltd
