Alexithymia is an important transdiagnostic risk factor for many psychopathologies. To explore its relevance for personality disorders, we examined the association between alexithymia and maladaptive personality traits, as conceptualized within the DSM-5-TR Alternative Model for Personality Disorders (i.e., negative affect, detachment, antagonism, disinhibition, psychoticism). Participants (N = 651) completed a battery of psychometric questionnaires. Regressions revealed that alexithymia facets accounted for a significant 15% of the variance in negative affect, 22% in detachment, 11% in antagonism, 18% in disinhibition, and 25% in psychoticism. Latent profile analysis showed that profiles with more severe personality pathology were generally characterized by more severe levels of alexithymia. Overall, our data highlight that alexithymia is important in understanding personality dysfunction. All facets of alexithymia, across both positive and negative emotions, are linked to each maladaptive personality trait. The assessment and targeting of alexithymia may therefore be of high relevance for the treatment of personality pathology.

Borderline personality disorder (BPD) is frequently understood as a diagnosis applicable mainly to women, despite population studies suggesting similar prevalence between men and women. The scarce available information suggests that compared to women, men may face additional gender-related barriers to diagnosis and treatment when attempting to engage with support and treatment for BPD-related difficulties. The current study presents a qualitative in-depth exploration of the help-seeking and diagnosis experiences of four men with BPD. Using Interpretive Phenomenological Analysis, three themes were generated: (1) "There's just no help out there": barriers to treatment; (2) self-understanding and insight; and (3) the importance of emotional and psychological connection with health care professionals and close family and friends. Having a greater understanding of male-specific experiences of BPD could improve the helpseeking journeys of men with BPD through early identification, accurate and timely diagnosis, to relevant and effective treatment and support.

While research has shown that the prevalence of ADHD in the general population has increased over time, there have been no studies focused on ADHD prevalence in patients with borderline personality disorder (BPD). This study compares two cohorts of adults with rigorously diagnosed BPD recruited nearly three decades apart (1992 vs. 2020). Participants from the 1992 McLean Study of Adult Development (MSAD) (N = 290) and the 2020 Flourishing study (N = 147) were assessed for ADHD using DSM-III-R and DSM-5 criteria respectively. Compared to MSAD subjects, the prevalence of ADHD among Flourishing subjects was significantly higher overall, and in female (but not male) subjects. This increased prevalence, which is likely due to the broadening of the DSM criteria over time, highlights what many observers believe to be a problematic expansion of the diagnostic criteria for ADHD that may have decoupled this criteria set from capturing a neurodevelopmental disorder that typically begins in childhood.

While existing literature suggests that posttraumatic stress disorder (PTSD) is frequently undetected in routine clinical practice, the detection rate of PTSD in patients with a personality disorder (PD) has not been investigated. This study examined the point prevalence of PTSD and frequency of trauma-focused treatment in 204 outpatients with a PD. Data were derived from electronic patient files. Compared to the mean weighted prevalence of PTSD in the literature, the Mini International Neuropsychiatric Interview Plus (MINI-Plus) found lower rates of PTSD for the entire sample (29.2%), but not separately for patients with borderline PD (BPD; 33.3%) and patients with other PDs (26.9%). In addition, PTSD diagnoses following intake were less prevalent for PD patients overall (18.6%), BPD patients (27%), and patients with other PDs (13.8%). The present study provides preliminary evidence that PTSD might be underdiagnosed and consequently unmanaged in PD patients in clinical practice, suggesting that the recognition of PTSD among patients with PD needs improvement.

We tested whether dimensional personality disorder models such as the Alternative Model for Personality Disorders (AMPD) cause less prejudice toward people with borderline personality disorder (BPD) than categorical models, and we sought to identify the mechanisms underpinning this reduction in prejudice. Undergraduate psychology students (n = 183) were randomly assigned to one of three conditions (AMPD, categorical, control) and given descriptive information about BPD. Participants in the AMPD and categorical conditions also received a presentation about their respective BPD diagnostic criteria. Students in all conditions then completed a survey assessing their prejudice toward people with BPD. There was no difference between conditions on overall prejudice toward people with BPD. However, the AMPD increased continuum beliefs and decreased categorical beliefs, and these, in turn, affected perceptions of people with BPD as ingroup members, which indirectly reduced prejudice. We have identified pathways through which the AMPD indirectly reduces prejudice toward people with BPD.

In the DSM-5 Alternative Model of Personality Disorders (AMPD), psychopathy is marked by the presence of attention seeking, low anxiousness, and lack of social withdrawal, along with traits from the domains of Antagonism and Disinhibition. The triarchic model of psychopathy (TriPM) posits three biobehaviorally based traits underlying it: disinhibition, meanness, and boldness. The current study directly compared relations for measures of the two models with the broad dimensions of externalizing, internalizing, and positive adjustment. Participants (1,678 adults) were surveyed regarding maladaptive personality traits, clinical symptoms, and positive adjustment features. The TriPM model explained more variance than the AMPD in substance use, positive adjustment, and empathy, whereas the AMPD model explained more variance in internalizing symptoms. In addition, AMPD Antagonism and the Psychopathy Specifier diverged from TriPM Meanness and Boldness in their associations with some specific outcomes. Overall, our study provides evidence for complementarity of the two models in characterizing the multifaceted nature of psychopathy.

Personality disorder (PD) is particularly common in adolescents, which underscores the significance of early screening, diagnosis, and intervention. To date, the definition of PD in the new ICD-11 has not yet been investigated in adolescents. This study therefore aimed to investigate the unidimensionality and criterion validity of self-reported ICD-11 PD features in Peruvian adolescents using the Personality Disorder Severity ICD-11 (PDS-ICD-11) scale. A total of 1,073 students (63% female; age range 12-16 years) were administered the PDS-ICD-11 scale along with criterion measures of personality pathology and symptom distress. The PDS-ICD-11 score showed adequate unidimensionality and conceptually meaningful associations with external criterion variables. The findings indicate that ICD-11 PD features, as measured with the PDS-ICD-11 scale, are structurally and conceptually sound when employed with adolescents. Norm-based cutoffs derived from the present study may be used for clinical interpretation. The PDS-ICD-11 may be employed as an efficient screening tool for personality dysfunction in adolescents.

The escalating global concerns surrounding radicalization and violent extremism necessitate a comprehensive understanding and explanation. Identifying the risk factors associated with radicalism and violent extremism is critical to the development of risk assessment, prevention, and intervention strategies. It is imperative to distinguish these risks from civic responsibilities (i.e., activism) to safeguard individual rights. This study aims to examine the association between well-established risk factors for violence-personality disorder symptoms-and violent extremist attitudes, radicalism, and activism. Findings indicate that antisocial personality disorder symptoms were linked to violent extremist attitudes and radicalism, whereas obsessive-compulsive disorder symptoms were related to activism. This suggests that obsessive-compulsive personality disorder may signify a readiness for legal and nonviolent political action; in contrast, antisocial personality disorder symptoms signify a readiness for extremist violence and illegal political action.

With the shift to the dimensional model of personality pathology, the need for measures assessing personality functioning in adolescence has emerged. The Levels of Personality Functioning Questionnaire 12-18 (LoPF-Q 12-18) was developed specifically for adolescents, tailoring the Alternative Model of Personality Disorders in the DSM-5. Using the Lithuanian LoPF-Q 1218, we further investigate its validity by reexamining its factorial structure and extending convergent, discriminant, and incremental validity analyses. A total of 1,048 community-based and clinically referred 12-18-year-old adolescents completed the LoPF-Q 12-18 along with other self-report measures of personality pathology, psychopathological symptoms, and psychosocial functioning. In line with previous findings, the results supported the bifactor model consisting of a strong general factor and little multidimensionality caused by the group factors, overall suggesting an essentially unidimensional structure. Further analyses provided additional information on the construct validity of the LoPF-Q 12-18.
