The linguistic equivalence of the Personality Inventory for DSM-5 (PID-5) has never been investigated using a within-subject design, that is, among bilingual individuals. Also, the stability-equivalence of the PID-5 using two linguistic versions is unknown. Thus, this within-subject, test-retest study aims at (a) establishing the measurement invariance of the PID-5 among bilinguals, and (b) providing indices of stability-equivalence using distinct versions with tight confidence intervals. Data from a sample of bilingual participants (N = 605), who were administered the PID-5 over a 1-2-week interval in French and English, were utilized. The PID-5 reached the (full) strong invariance level using longitudinal invariance analyses, indicating that the PID-5 structure is the same and that scores are interchangeable, while controlling for sampling confounds. The indices of stability-equivalence were high across traits. The PID-5 yields scores reflective of genuine differences, at least at the domain level, providing solid ground to study personality across societies.

To compare the effectiveness of the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), Section II personality disorder (PD) model, and of the Alternative Model for Personality Disorders (AMPD) model in characterizing vulnerable (VN) and grandiose (GN) narcissism, a sample of clinical psychotherapy participants (N = 369) was administered the Schedule for Nonadaptive and Adaptive Personality-2, the Levels of Personality Functioning Scale-Self Report (LPFS-SR), the Personality Inventory for DSM-5, the Five-Factor Narcissism Inventory-Short Form (FFNI-SF), and the Pathological Narcissism Inventory (PNI). In multiple regression models, the LPFS-SR scales and the Personality Inventory for DSM-5 (PID-5) domain scales explained 34.6% and 23.7% more variance than the self-reports of the 10 Section II PD symptom counts in the FFNI-SF and PNI GN scores, respectively. Similarly, AMPD measures outperformed self-reported symptom counts of the 10 Section II PDs, accounting for 28.8% and 22.6% more variance in the FFNI-SF and PNI VN scale scores, respectively.

A higher prevalence of personality disorder diagnoses has been found among individuals with gender dysphoria. However, previous studies on this topic have been limited and methodologically inconsistent. The object of this research was to determine the prevalence of personality disorder diagnoses in individuals requesting medical gender reassignment. A registerbased follow-up study tracked individuals who contacted the nationally centralized gender identity services in Finland in 1996-2019 (n = 3,665) and 8:1 age- and sex-matched population controls (n = 29,292). All their specialist-level psychiatric treatment contacts in 1994-2022 were identified in the National Care Register for Health Care. ICD-10 diagnoses and dates of the contacts were extracted. Among the gender dysphoria group, 15.0% (551 out of 3,665) had received a diagnosis in the personality disorder group (F60-69 excluding F64.x), while among the control subjects, 2.1% (625 out of 29,292) had received such a diagnosis.

The aim of this study was to assess emotional dysregulation (ED) and sexual risk behavior (SRB) in borderline personality disorder (BPD) and to investigate the relationship between ED, SRB and other clinical variables. Sixty-one women with BPD and 76 healthy controls (HCs) completed: SRB Scale, DERS, Inventory of Statements About Self-Injury, SUPPS-P, HADS, Mental Pain Scale, and BPD Checklist. The BPD group exhibited higher levels of ED, SRB, psychological pain, anxiety, depression, and impulsivity than the HCs. In the BPD group, significant correlations were found between ED, SRB, and psychological pain, impulsivity, and specific dimensions of nonsuicidal self-injury (NSSI). To identify predictors of SRB, stepwise multiple regression analysis was used. The BPD model included five significant predictors accounting for 65% variability: number of sexual partners and age of sexual initiation, NSSI, impulsivity, and ED - lack of emotional clarity, while in HCs, it was influenced by alcohol misuse.

Obsessive-compulsive personality disorder is the most common personality disorder, with a prevalence of approximately 6.5% in the general population. However, little is known about the effective psychotherapy for this disorder. In this case series, we employed evolutionary systems therapy to support five adults diagnosed with obsessive-compulsive personality disorder. Evolutionary systems therapy is a novel form of psychotherapy that integrates evolutionary psychopathology, compassion-focused therapy, and metacognitively oriented treatments. Primary outcome (personality pathology) was assessed monthly from baseline to follow-up. Secondary outcomes (anxiety, depression, perfectionism, self-criticism, overcontrol) were assessed at initial and final sessions. Moreover, we evaluated the feasibility of intervention (completion, attendance, adverse events). At the end of 6 months of treatment, all the participants reported reliable changes and remitted from diagnosis. These outcomes were maintained at 1-month and 3-month follow-ups. Further research is needed to provide evidence about the acceptability of evolutionary systems therapy in the treatment of obsessive-compulsive personality disorder.

Advanced empirical research and clinical theory suggest that narcissistic personality states fluctuate over time. However, these fluctuations are poorly understood. To address this, we recruited 88 undergraduates to complete baseline measures and respond to smartphone prompts assessing narcissistic states and emotions in daily life seven times a day for 10 days. Narcissistic states were assessed using a state-adapted version of the Super Brief Pathological Narcissism Inventory (SB-PNI). Findings showed that within-person covariation of narcissistic states ranged from -.55 to .52 and was negatively associated with trait grandiosity, guilt, and mood activation. In addition, there was a significant quadratic relationship between narcissistic covariation and trait vulnerability and between narcissistic covariation and mean state vulnerability, self-esteem, pleasant and activated mood, and shame across 10 days. These findings suggest a potential state-based dynamic taxonomy of narcissistic presentations and highlight the importance of understanding distinctions between co-occurring, contrasting, and dissociated narcissistic states.

Borderline personality disorder (BPD) and eating disorders (EDs) frequently co-occur. The present study investigated whether treatment-seeking patients with BPD and a comorbid ED experienced increased risk of self-harm or suicide behaviors. In a sample of 350 patients with BPD, 61 (17.4%) had a comorbid ED: 25 (7.1%) had bulimia nervosa (BN), 15 (4.2%) had an eating disorder not otherwise specified (EDNOS), 13 (3.7%) had bingeeating disorder (BED), and 8 (2.2%) had anorexia nervosa (AN). Comorbid BED and AN were individually significantly associated with recurrent suicide attempt over the past year, while comorbid AN was associated with greater lethality of recent self-harm. These results suggest that ED diagnosis may constitute a risk factor for self-harm and suicide behaviors in patients with BPD.

Psychopathy encompasses a constellation of personality traits-including callousness, boldness, and disinhibition-associated with lifetime outcomes such as criminal activity, substance use, aggression, and other antisocial behaviors. However, psychopathy's relationship with these outcomes can vary depending on the sample tested, and no prior study has assessed outcomes related to psychopathy in a representative U.S. population sample. We thus assessed the relationship between psychopathy and relevant outcomes using the Triarchic Psychopathy Measure (TriPM) administered to a sample recruited to be demographically representative of American adults (N = 289). Results showed that TriPM psychopathy was normally distributed and associated with antisociality and criminal behavior. Unlike some prior results, we found that neither gender nor income moderated the relationship between psychopathy and criminal behavior. Disinhibition and boldness subscales, but not meanness, were associated with criminal behavior. These results underscore the importance of understanding psychopathy in the general population to improve public safety and health.

Psychopathy is a personality disorder characterized by affective-interpersonal features and an impulsive-antisocial lifestyle. Psychopathy commonly co-occurs with other forms of psychopathology, but current understanding of how behavioral features of psychopathy co-occur with, or are distinct from, other mental health problems is limited. In this study, we analysed data from a large sample of young adults to study the relationship between different facets of psychopathic traits and general psychopathology ("p"). Data were collected between 2010 and 2016 and included 1,324 U.S. undergraduate students (M_age = 19.7 years; 57% female). Linear regression models revealed that the antisocial facet of psychopathy was distinct from p, while the lifestyle facet was correlated with p and externalizing behavior. Interpersonal and affective facets were correlated with internalizing behaviors. Collectively, these findings suggest that psychopathic traits of severe, premeditated antisocial behavior are distinct from general psychopathology, whereas impulsive and uninhibited lifestyle traits are a shared feature of psychopathology.

The degree to which schizoid and avoidant personality styles represent unique variants of interpersonal detachment remains controversial. This study contrasted core traits associated with schizoid versus avoidant personalities in a mixed-sex sample of 221 community adults, using the five traits that comprise the Alternative Model for Personality Disorders (AMPD). The International Personality Disorders Examination Screening Questionnaire was used to assess schizoid and avoidant personality traits; the Personality Inventory for DSM-5 was used to assess negative affectivity, detachment, antagonism, disinhibition, and psychoticism. As expected, schizoid and avoidant scores were both positively associated with AMPD detachment scores (rs were .68 and .57, respectively). Regression analyses confirmed that, in addition to detachment, high levels of negative affectivity and low levels of disinhibition were uniquely predictive of avoidant personality traits, whereas low levels of antagonism were uniquely predictive of schizoid personality traits. The present findings support the distinctiveness of these two contrasting expressions of detachment.
