The DSM-5 Section III alternative model of personality disorder (AMPD) and the International Classification of Diseases - 11th Edition's (ICD-11) personality disorder classification allow clinicians to identify individual trait domains in which people score highly. However, how these domains relate to constructs associated with efficacious treatment approaches is unclear. The current study aimed to determine whether constructs from two evidence-based treatments (schema therapy [ST] and dialectical behavior therapy [DBT]) were associated with maladaptive personality traits in a way consistent with underlying theories. We examined associations between ST constructs, DBT skill use and maladaptive coping styles, and personality traits in a sample of 525 adults. Bivariate intercorrelations and a series of multiple regression analyses were conducted to investigate the associations. As hypothesized, maladaptive coping was strongly associated with all trait domains. Surprisingly, poor DBT-skill use was only associated with negative affectivity, detachment, and disinhibition trait domains. Specific schema domains were associated with each personality trait domain, supporting trait domain-schema domain specificity. The current study highlights the potential clinical utility of the AMPD and ICD-11 trait models and ultimately contributes to the dearth of evidence on their likely usefulness for treatment selection, planning, and applications.

The Alternative Model of Personality Disorders (AMPD) is a relatively new dimensional model of personality disorders (PDs) that assesses two diagnostic constructs: personality functioning and pathological personality traits. Thus far, research on the AMPD among older adults has been limited, but the research that does exist suggests limited generalizability to the unique biopsychosocial context of later life. To further examine the applicability of the AMPD to older adults, the purpose of this study was to examine relationships between the AMPD's two constructs with perceived physical health status among younger and older adult samples. Older adults (n = 222) and younger adults (n = 215) completed the Short Form-36 (SF-36), Levels of Personality Functioning Scale-Self-Report (LPFS-SR), and Personality Inventory for DSM-5-Brief Form (PID-5-BF). Correlations and Fisher's z-tests revealed significantly stronger relationships between the SF-36 with the LPFS-SR and PID-5-BF domains for older adults than younger adults. Additionally, age group significantly moderated the relationships between personality functioning and pathological personality traits and health. The stronger relationships between health and the AMPD's constructs for older adults suggest meaningful overlap between negative health outcomes and PD pathology. Future research should further investigate specific mechanisms in which personality pathology negatively impacts health in older adults.

Antisocial personality disorder (ASPD) is a common behavioral pattern that causes sufferers to ignore or violate the rights of others. Though its cause is still unclear, previous studies have shown that childhood maltreatment is closely related to ASPD. The NOS1AP gene is associated with various neuropsychiatric diseases, but a linkage between it and ASPD has not yet been discovered. This study recruited ASPD and non-ASPD male subjects who had committed violent crimes from a prison in Nanjing, China. By comparing the two groups' genotypes, allele frequencies, and histories of childhood abuse, we explored the interaction between the NOS1AP gene and childhood maltreatment on the pathogenesis of ASPD. The results showed that polymorphism rs945713 in the NOS1AP gene was associated with ASPD and furthermore that this SNP may be involved in regulating the effect of childhood abuse on ASPD. This study found that childhood trauma increases the risk of ASPD in violent adult male inmates; for prisoners with ASPD, it is critical to pay attention to their childhood trauma and take early psychological intervention.

The Hierarchical Taxonomy of Psychopathology (HiTOP) organizes phenotypes of mental disorder based on empirical covariation, offering a comprehensive organizational framework from narrow symptoms to broader patterns of psychopathology. We argue that established self-report measures of psychopathology from the pre-HiTOP era should be systematically integrated into HiTOP to foster cumulative research and further the understanding of psychopathology structure. Hence, in this study, we mapped 92 established psychopathology (sub)scales onto the current HiTOP working model using data from an extensive battery of self-report assessments that was completed by community participants and outpatients (N = 909). Content validity ratings of the item pool were used to select indicators for a bifactor-(S-1) model of the p factor and five HiTOP spectra (i.e., internalizing, thought disorder, detachment, disinhibited externalizing, and antagonistic externalizing). The content-based HiTOP scales were validated against personality disorder diagnoses as assessed by standardized interviews. We then located established scales within the taxonomy by estimating the extent to which scales reflected higher-level HiTOP dimensions. The analyses shed light on the location of established psychopathology scales in HiTOP, identifying pure markers and blends of HiTOP spectra, as well as pure markers of the p factor (i.e., scales assessing mentalizing impairment and suspiciousness/epistemic mistrust).

Although uncommon, borderline personality disorder (BPD) may manifest for the first time later in life. A retrospective clinical file audit was used to identify the clinical manifestation of BPD for the first time at or above the age of 30, and to examine whether particular clinical and psychosocial factors may be associated with a later-in-life manifestation of BPD. Twenty-three cases of late manifestation BPD were identified. People with late manifestation of BPD had similar risk factors and vulnerabilities, including childhood trauma, to the broader BPD population. They were distinguished by having higher levels of education, employment, and long-term intimate relationships. Interpersonal problems, loss of employment and reminders of past sexual trauma were key precipitating factors. The findings underscore the legitimacy of a late-manifestation diagnosis of BPD by demonstrating that BPD does not present exclusively during adolescence and early adulthood. BPD may present for the first time in later life in response to loss of protective factors or triggering of past trauma. This understanding may reduce misdiagnosis or delayed diagnosis, prescription of inappropriate treatments or delays in receiving BPD-appropriate treatments.

Emerging dimensional models of personality disorders such as the Alternative DSM-5 Model for Personality Disorders (AMPD) provide new opportunities to explore the associations between personality pathology and harmful interpersonal behaviours such as stalking perpetration. Two goals are pursued by this study: (a) To document associations between stalking, level of personality pathology, and pathological personality domains/facets; and (b) to determine the relative importance of maladaptive personality facets in the statistical prediction of stalking. Data from 1489 young adults (18-30 years old) from a community sample were analysed. Moderate positive significant correlations were found between stalking, level of personality pathology, and maladaptive personality domains. A clear gradient of severity of stalking behaviours was found across five severity degrees of personality pathology. Dominance analyses revealed that Deceitfulness was the most dominant statistical predictor in women. Unusual Beliefs and Experiences, a facet from the Psychoticism domain, made an important contribution in the prediction of stalking in men only. Impulsivity was a key predictor in both genders but more markedly in men. Results suggest that the AMPD represents a useful framework to study stalking perpetration. Identification of key personality predictors might prove relevant for identifying risk factors, underlying motives, and treatment targets for stalking perpetrators.

Obesity is a chronic disorder associated with high mortality rates and high morbidity. The risk of obesity is associated with certain personality traits (PTs). Some studies have found correlations among some PTs and gender. Additionally, obesity implies higher costs in daily living. The aim of this paper is to overcome this problem in the literature and estimate the association between PTs and obesity by taking into account the economic situation of the individual. This study employs data from the English Longitudinal Study of Ageing (ELSA). We focus on waves 5 and 6 of the ELSA with a sample of 6562 individuals. The results suggests that the traits of agreeableness ( $\beta =0.071,\mathrm{se}=0.016,p<0.001$ ) and openness ( $\beta =0.028,\mathrm{se}:0.014,p<0.001$ ) are positively and significantly associated with obesity. On the other hand, consciousness has a negative and statistically significant effect on obesity $\left(\beta =0.072,\mathrm{se}:0.017,p<0.001\right)$ . Results are robust to the inclusion/exclusion of different regressors.

We aimed to determine the prevalence of borderline personality disorder (BPD) symptoms in a sample of eating disorder (ED) outpatients and assess how BPD symptoms correlate with severity, distress, and function. A total of 119 individuals were assessed and divided into high BPD symptoms (H-BPD) and low BPD symptoms (L-BPD) using a cut-off score of seven on the McLean Screening for Borderline Personality Disorder (MSI-BPD). Groups were compared on ED diagnosis, age at ED onset, age at assessment, illness duration, body mass index (BMI), ED symptomatology, psychological distress, and psychosocial function. Correlation analyses were performed to assess the relationship between BPD symptoms and these variables. The 45.4% of the participants scored ≥7 on the MSI-BPD, indicating a diagnosis of BPD. There were no differences between the H-BPD (N = 54) and L-BPD (N = 65) groups on age at onset, age at assessment, duration of illness, BMI, or proportion of ED diagnosis. The H-BPD group reported significantly higher ED symptomatology, psychological distress, and poorer psychosocial functioning. MSI-BPD scores were positively associated with these variables. This study suggests a high prevalence of BPD symptoms within outpatients seeking ED treatment, and use of a brief screening instrument for BPD in this group may contribute to a greater understanding of the patient.

The Level of Personality Functioning Scale-Brief Form 2.0 is a frequently used self-report inventory that may be used to screen for self- and interpersonal dysfunction according to the DSM-5 Alternative Model for Personality Disorders (AMPD) and the ICD-11 Classification of Personality Disorders. Nevertheless, reliable norms and cut-off scores to aid interpretation and clinical decision making are still lacking. The LPFS-BF and relevant impairment measures were administered to a sociodemographically stratisfied sample of 2,002 adults from the general Danish population of whom 713 individuals eventually delivered data for inclusion in the present study. The unidimensionality of the LPFS-BF scores was established using Confirmatory Factor Analysis (CFA). Item-Response Theory (IRT) analysis indicated satisfactory item functioning for all 12 items and suggested normative observed score thresholds at different latent severity levels. Meaningful associations were found between the LPFS-BF norm-based cut-off scores, quality of life, and social and occupational functioning. This study presented the first normative data for LPFS-BF, which specifically applies to Denmark but likely also other socioeconomically comparable Nordic and Western societies. These results allow for interpretation of LPFS-BF scores and clinical decision-making. Future research should corroborate these findings and compare them to scores obtained in other general population samples.

Individuals with personality disorders (PDs) have a decreased life expectancy compared with the general population in part due to physical illnesses. Many hypotheses have been suggested to explain those physical illnesses such as hormone imbalance, medication, lack of physical activity, and unhealthy diet. However, little is known about the relation between lifestyle and PDs. The purpose of this scoping review is to regroup the available information on this topic. We searched the literature up to February 2021 using four databases and found 21 articles analyzing the relation between lifestyle and PDs in observational studies including 153,081 participants from diverse populations going from general population to adults in psychiatric care. Most studies used measures of lifestyle as control variables or did not use lifestyle variables at all. Moreover, the instruments used to measure lifestyle variables lacked precision at best. Two studies demonstrated a relation between early malnutrition and further development of PDs, but those results may be influenced by confounding variables and cannot indicate a clear link between nutrition and personality disorder. The lack of solid evidence we observed is surprising, considering the multiple benefits individuals with PDs could get from a healthy lifestyle. More studies are needed to thoroughly analyze the impact of lifestyle on PDs and vice versa.
