Abstract

INTRODUCTION: Personality Disorders (PD) are highly prevalent among Chronic Fatigue Syndrome (CFS) patients, but studies based on the DSM-5 are still scarce. Validated instruments have not yet been specifically used in CFS patients. Therefore, our aim was to analyze the differences in personality facets and domains profiles among CFS patients with and without a PD using the Personality Inventory for DSM-5 (PID-5). Additionally, we analyzed the ability of this instrument to predict PD in a sample of CFS patients. This instrument is validated for PDs, but not for CFS. METHODS: All of the 84 CFS patients were evaluated through a clinical interview and underwent psychopathological evaluation with the SCID I and SCID II. Dimensional personality facets and domains were evaluated with the PID-5, according to DSM-5. RESULTS: In our sample, 54 (64%) of the patients fulfilled the criteria of a PD. The most significant facets in CFS with PD in comparison to those patients without a PD were Separation Insecurity, Perseveration, Withdrawal, Depressivity, Rigid Perfectionism, Unusual Beliefs and Experiences. Negative Affectivity and Detachment were the two significant domains in CFS-PD patients. In the regression analyses, only Detachment and Rigid Perfectionism constituted a prognostic factor leading to high probability of an endorsed PD. Conclussion. According to these results, the PID-5 domains and facets could be adequate and useful to differentiate between PD and non-PD patients in clinical samples and suggest a more frequent dimensional personality profile in CFS patients.
