Dimensional Personality Assessment among a Chronic Fatigue Syndrome (CFS) sample with Personality Inventory for DSM-5 (PID-5).

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.

Describing Callous Unemotional Traits and Stressful Life Event Trajectories: Differences on Risk Factors and Mental Health Outcomes from the Age of 3 to 10.

Callous Unemotional (CU) traits are associated with different environmental risk factors, such as negative stressful life events (SLE). The most common studied SLE associated with CU trait has been childhood maltreatment, but less is known about how other SLE impact the development of CU traits. Therefore, this work examines risk factors, personal factors (executive functioning), and mental health outcomes associated with the trajectories of Callous Unemotional (CU) traits and Stressful Life Events (SLE) in a community sample of children. A cohort of 377 preschoolers were followed up between ages 3 and 10. Several risk factors and outcomes for three trajectory groups (high CU/SLE; high CU/low SLE; and the reference group with low CU/SLE) were analyzed by using multiple post-hoc comparisons. We hypothesized that children with high CU/SLE would face more contextual risk factors, more executive functioning difficulties and more mental health problems than children with high CU/low SLE or the reference group. At the age of 3, children who showed high CU/SLE faced more early contextual adversity, including socioeconomic difficulties and maternal antisocial behavior than the other groups of children. At the age of 10, children with high CU/SLE presented more peer problems and higher psychopathology symptoms than the reference group, but no differences on mental health outcomes in comparison to the high CU/low SLE group. These results have potential implications for clinical practice and studies attempting to identify different CU subtypes in children.

Age and sex-specific cutoff scores for the teacher-report inventory of callous-unemotional traits on children.

This longitudinal study aims to provide meaningful cutoff scores for total score of the teacher-rated Inventory of Callous-Unemotional Traits (ICU) from the preschool age until early adolescence, separately by age and sex. The ICU cutoff scores were determined by using low/high trajectories of oppositional defiant problems (ODP) and conduct problems in a Spanish community sample of 620 children that were followed up between the ages of 3 and 13. Receiver operating characteristic (ROC) curves with the two trajectories as criteria and ICU total score at each age as a predictor were estimated by sex separately, and the area under the ROC curve (AUC) was obtained. Average ICU cutoff scores of 26 for boys and 22 for girls were found to be of moderate utility for the prediction of high trajectories of each of ODP and conduct problems. They identified cases with an average sensitivity of 66% and specificity of 70% for boys and an average sensitivity of 69% and specificity of 72% for girls. The obtained cutoff scores might help clinical practitioners in their decision-making process when identifying low and high-risk groups of children.
