Abstract
The interpersonal problem circumplex is extensively used in the field as an assessment framework for understanding the interpersonal implications of a range of personality and psychopathology constructs. The vast majority of this large literature has been conducted in Western convenience and clinical samples. We computed interpersonal problem structural summary parameters for a range of personality and psychopathology variables in two Chinese offender samples (N = 424 and N = 555) and one undergraduate sample (N = 511) to test how well findings from Western samples generalize to Chinese undergraduates and offenders. The results showed that findings in Western samples generalized reasonably well to Chinese young adult and forensic contexts, although the interpersonal profiles of external variables were less specific in Chinese samples. Compared with undergraduates, interpersonal distress has stronger associations with the mental health of offenders. This study further elaborates the interpersonal correlates of individual differences in personality and psychopathology across cultures and assessment contexts, and it also extends the literature examining interpersonal problems in forensic settings.

Abstract
Over the past several decades, significant criticism of the categorical classification system for personality disorders has highlighted the need to transition to a dimensional classification system. This study reviewed key issues involved in the potential conversion of the diagnostic system of personality disorders from a categorical to a dimensional model. The result suggests that Kernberg's concept of personality organization can be used to indicate the overall severity of personality pathology.

Personality disorder coverage, prevalence, and convergence: do the DSM-5's two models of personality disorder identify the same patients? Psychol Med 2024:1-12.

Abstract
BACKGROUND Research on the Alternative DSM-5 Model for Personality Disorders (AMPD) in DSM-5's Section-III has demonstrated acceptable interrater reliability, a largely consistent latent structure, substantial correlations with theoretically and clinically relevant measures, and evidence for incremental concurrent and predictive validity after controlling for DSM-5's Section II categorical personality disorders (PDs). However, the AMPD is not yet widely used clinically. One clinician concern may be caseness - that the new model will diagnose a different set of PD patients from that with which they are familiar. The primary aim of this study is to determine whether this concern is valid, by testing how well the two models converge in terms of prevalence and coverage. METHOD Participants were 305 psychiatric outpatients and 302 community residents not currently in mental-health treatment who scored above threshold on the Iowa Personality Disorder Screen (Langbehn et al., ). Participants were administered a semi-structured interview for DSM-5 PD, which was scored for both Section II and III PDs. RESULTS Convergence across the two PD models was variable for specific PDs, Good when specific PDs were aggregated, and Very Good for 'any PD.' CONCLUSIONS Results provide strong evidence that the AMPD yields the same overall prevalence of PD as the current model and, further, identifies largely the same overall population. It also addresses well-known problems of the current model, is more consistent with the ICD-11 PD model, and provides more complete, individualized characterizations of persons with PD, thereby offering multiple reasons for its implementation in clinical settings.

Unravelling the Longitudinal Relations Between Developmental Milestones, General Psychopathology, and Personality Functioning in a Youth Clinical Sample. J Youth Adolesc 2024:10.1007/s10964-024-01971-2.

Abstract
Personality functioning, general psychopathology, and developmental milestones achievement are critical domains in the field of young people's mental health; however, no prior research has considered these variables jointly or examined the temporal dynamics between them. To fill these gaps, the present study aimed to investigate the longitudinal associations between the above constructs in a clinical sample of Dutch youth. 525 outpatients (72.5% women; age range: 12-26 years, M = 18.8 ± 2.83) diagnosed with different psychological difficulties were recruited from specialized mental health care services in The Netherlands. They completed self-report measures assessing personality functioning, psychopathological symptoms, and the achievement of youth-specific developmental milestones. Data were collected on three occasions within a year and modelled using a Cross-Lagged Panel Model approach. The levels of personality dysfunction, general psychopathology, and developmental milestones achievement were found to fluctuate from one wave to the other. Personality dysfunction and general psychopathology were positively interrelated at each time point, while both constructs were negatively associated with developmental milestones achievement. Importantly, difficulties achieving developmental milestones predicted a worsening in personality functioning 6 months later. This result would suggest that the achievement of developmental milestones precedes personality functioning, supporting the importance of interventions promoting age-adequate functioning in youth.

Transdiagnostic psychopathology in the light of robust single-trial event-related potentials. Psychophysiology 2024:e14562.

Abstract
Recent evidence indicates that event-related potentials (ERPs) as measured on the electroencephalogram (EEG) are more closely related to transdiagnostic, dimensional measures of psychopathology (TDP) than to diagnostic categories. A comprehensive examination of correlations between well-studied ERPs and measures of TDP is called for. In this study, we recruited 50 patients with emotional disorders undergoing 14 weeks of transdiagnostic group psychotherapy as well as 37 healthy comparison subjects (HC) matched in age and sex. HCs were assessed once and patients three times throughout treatment (N = 172 data sets) with a battery of well-studied ERPs and psychopathology measures consistent with the TDP framework The Hierarchical Taxonomy of Psychopathology (HiTOP). ERPs were quantified using robust single-trial analysis (RSTA) methods and TDP correlations with linear regression models as implemented in the EEGLAB toolbox LIMO EEG. We found correlations at several levels of the HiTOP hierarchy. Among these, a reduced P3b was associated with the general p-factor. A reduced error-related negativity correlated strongly with worse symptomatology across the Internalizing spectrum. Increases in the correct-related negativity correlated with symptoms loading unto the Distress subfactor in the HiTOP. The Flanker N2 was related to specific symptoms of Intrusive Cognitions and Traumatic Re-experiencing and the mismatch negativity to maladaptive personality traits at the lowest levels of the HiTOP hierarchy. Our study highlights the advantages of RSTA methods and of using validated TDP constructs within a consistent framework. Future studies could utilize machine learning methods to predict TDP from a set of ERP features at the subject level.

Abstract
Personality disorders (PDs) are associated with an inferior quality of life, poor health, and premature mortality, leading to heavy clinical, familial, and societal burdens. The International Classification of Diseases-11 (ICD-11) makes a thorough, dramatic paradigm shift from the categorical to dimensional diagnosis of PD and expands the application into adolescence. We have reviewed the recent literature on practical implications, and severity and trait measures of ICD-11 defined PDs, by comparing with the alternative model of personality disorders in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), by mentioning the relevance in forensic and social concerns, and by referencing the developmental implication of life span, especially in adolescence. Study results strongly support the dimensional utility of ICD-11 PD diagnosis and application in adolescence which warrants early detection and intervention. More evidence-based research is needed along the ICD-11 PD application, such as its social relevance, measurement simplification, and longitudinal design of lifespan observation and treatment.

Abstract
Research on Criterion A of the alternative model for personality disorders is recently expanding and provides mixed results concerning the unidimensional operational definition of severity by the model, characterized by impaired self (identity and self-direction) and interpersonal (empathy and intimacy) functioning. Studies resulted in one, as well as two or more factor structures. The present study demonstrated the importance of the structural and relational differentiation of self and interpersonal dimensions of personality functioning. One thousand seventy-four participants (community and clinical mixed sample) completed the Level of Personality Functioning Scale - Brief Form 2.0 (LPFS-BF 2.0), the Personality Inventory for DSM-5 Short Form and the Questionnaire for the World Health Organization Disability Assessment. An LPFS-BF 2.0 two-factor structure with self and interpersonal functioning factors was corroborated by confirmatory factor analyses and bifactor modeling. Joint Exploratory Factor Analysis of the LPFS-BF 2.0 domains with maladaptive personality domains clearly differentiated the personality functioning factors. While the self-functioning factor was more closely linked to negative affect (and to disinhibition and psychoticism), the interpersonal functioning factor connected to detachment. Self-functioning predicted functional impairment along and beyond personality domains. The LPFS-BF 2.0 appears a useful tool for clinical routine monitoring of both self and interpersonal functioning.

Abstract
The Personality Assessment Inventory (PAI) is a broadband measure of psychopathology that is widely used in applied settings. Researchers developed regression-based estimates that use the PAI to measure constructs of the Alternative Model for Personality Disorders (AMPD) - a hybrid dimensional and categorical approach to conceptualizing personality disorders. Although prior work has linked these estimates to formal measures of the AMPD, there is little work investigating the clinical correlates of this scoring approach of the PAI. The current study examines associations between these PAI-based AMPD estimates and life data in a large, archival dataset of psychiatric outpatients and inpatients. We found general support for the criterion validity of AMPD estimate scores, such that a theoretically consistent pattern of associations emerged with indicators such as prior academic achievement, antisocial behavior, psychiatric history, and substance abuse. These results provide preliminary support to this scoring approach for use in clinical samples.

Abstract
The Level of Personality Functioning - Brief Form 2.0 (LPFS-BF 2.0) is a 12-item self-report questionnaire developed to gain a quick impression of the severity of personality pathology according to the DSM-5 Alternative Model for Personality Disorders (AMPD). The current study evaluated the construct validity and reliability of the Norwegian version of the LPFS-BF 2.0 in a large clinical sample (N = 1673). Dimensionality was examined using confirmatory factor analysis and bifactor analysis followed by an analysis of distinctiveness of the subscales using the proportional reduction in mean squared error (PRMSE), and the concurrent validity was examined using correlations with self-report questionnaires and clinical interviews assessing PDs according to section II of the DSM-5. Taking the findings of the dimensionality and concurrent validity results together, we found moderate to good support for the use of total scores for the Norwegian version of the LPFS-BF 2.0. We would advise against the use of subscale scores, since the subscales provided only a small amount of reliable unique variance.

Abstract
The purpose of this article is to provide a description and discussion of the evidence-based assessment of personality disorder. Considered herein is the assessment of the Section II personality disorders included within the fifth edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (5th ed., text rev.; DSM-5-TR), within Section III of DSM-5-TR, and within the 11th edition of the World Health Organization's International Classification of Diseases (WHO). The recommendation for an evidence-based assessment is for a multimethod approach: first administer a self-report inventory to alert the clinician to maladaptive personality functioning that might not have otherwise been anticipated, followed by a semi-structured interview to verify the personality disorder's presence. The validity of this multimethod strategy can be improved further by considering the impact of other disorders on the assessment, documenting temporal stability, and establishing a compelling, empirical basis for cutoff points.

Abstract
BACKGROUND The Work and Social Adjustment Scale (WSAS) is a self-administered measure designed to assess the level of inability to function socially as a consequence of a defined problem or disorder. METHODS A total of 230 patients with emotional disorders completed the Danish translation of the WSAS, measures of anxiety and depression, the Level of Personality Functioning Brief Form, the Personality Inventory for DSM-5 Short Form, and the World Health Organization Five-Item Well-Being Index (WHO-5). We conducted a confirmatory factor analysis of the previously suggested factor structure of the instrument. We furthermore evaluated the construct validity of the WSAS by means of its relationship with depression, anxiety, personality functioning, and overall well-being. Finally, we evaluated the utility of the WSAS to identify those on long-term sick-leave by conducting receiver operating characteristic (ROC) curves. RESULTS The instrument had a poor to average fit with the previously reported single-factor structure, but a better fit to a modified single-factor structure. Cronbach's alpha and McDonald's omega showed good internal scale reliability (α = .79, ωtotal = .85). WSAS was positively correlated with measures of anxiety (r = .33), depression (r = .44), and personality functioning (r = .23 and r = .20), and negatively correlated with WHO-5 wellbeing (r = -.57). The optimal cut-off point in the ROC-analyses was 23, which yielded a sensitivity of 74% and a specificity of 55% in the prediction of sick-leave status. DISCUSSION The Danish WSAS shows promising psychometric properties, but has limited external validity insofar as predicting long-term sick leave in psychiatric patients with emotional disorders.

Abstract
Personality disorders (PDs) are associated with high levels of societal costs. However, previous research has found limited or no evidence of unique contributions of individual PD categories on the overall level of societal costs. Recent research supports the validity of PD as a dimensional construct, and PD severity may be a better predictor of societal costs than specific PD categories. The aim of this study was to explore if PD severity could predict the level of societal costs among treatment-seeking patients with PDs, while controlling for the impact of comorbid mental health and substance use disorders. Four different severity indicators were explored: the number of PDs, the total number of PD criteria, the number of BPD criteria, and the Level of Personality Functioning Scale (LPFS) from the alternative model in DSM-5. Participants (n = 798/794) were retrieved from the quality register of the Norwegian Network for Personality Disorders for the period 2017-2020. Societal costs were assessed using a structured interview covering the six-month period prior to assessment. Diagnoses and diagnostic criteria were determined using a semi-structured diagnostic interview (SCID-5-PD and M.I.N.I), and the LPFS was assessed by the LPFS-Brief Form 2.0 (LPFS-BF 2.0) questionnaire. Statistics included multiple regression analyses. None of the severity indicators were significant predictors of overall societal costs among treatment-seeking patients, and effect sizes were small.

Abstract
BACKGROUND Self-harm in young people is a public health concern connected with severe mental health problems, such as personality pathology. Currently, there are no specific evidence-based interventions available for young people who self-harm. Therefore, we developed PRe-Intervention Monitoring of Affect and Relationships in Youth (PRIMARY), a smartphone-based intervention, co-designed by clinicians and young people with lived experience of mental ill-health. PRIMARY combines the Experience Sampling Method (ESM) with weekly report sessions. The study aims to examine the effectiveness of PRIMARY with regard to reducing self-harm, and improving emotion regulation and quality of relationships. METHODS This study is a multicenter, parallel groups, randomized controlled trial (RCT) comparing the PRIMARY intervention to a waiting list control group. PRIMARY comprises 28 consecutive days of questionnaires five times each day (i.e., ESM) and four weekly report sessions. Participants will comprise 180 young people referred for treatment to the participating Dutch mental healthcare institutions and (1) are aged 12 to 25 years, and (2) engaged in ≥ 1 act of self-harm in the past year. Participants are randomly allocated to a study group after screening in a 1:1 ratio by an independent researcher using computer-generated randomization sequences with stratified block randomization by age (12 to 15 years / 16 to 25 years). Staff will conduct assessments with all participants at baseline (Wave 1), after 28 days (Wave 2), and in a subsample after 10 weeks of subsequent specialized treatment (Wave 3). The primary outcomes are self-harm, emotion regulation, and quality of relationships. Secondary outcomes include patient and clinician satisfaction. Exploratory analyses of ESM data will examine the relationship between emotions, social relationships, and self-harm. DISCUSSION The results of this trial will clarify whether an innovative smartphone-based intervention is effective for reducing self harm and improving emotion regulation and the quality of social relationships. It has the potential to fill a treatment gap of interventions specifically targeting self-harm. If proven effective, it would provide an accessible, easy-to-implement, low-cost intervention for young people. Furthermore, the ESM-data will allow detailed analyses into the processes underlying self-harm, which will contribute to theoretical knowledge regarding the behavior.

Abstract
The Self and Interpersonal Functioning Scale (SIFS) is a 24-item self-report questionnaire assessing personality functioning according to the alternative DSM-5 model for personality disorders. We evaluated the German SIFS version in a total sample of 886 participants from Germany and Switzerland. Its factor structure was investigated with confirmatory factor analysis comparing bifactor models with two specific factors (self- and interpersonal functioning) and four specific factors (identity, self-direction, empathy, and intimacy). The SIFS sum and domain scores were tested for reliability and convergent validity with self-report questionnaires and interviews for personality functioning, -organization, -traits, -disorder categories, and well-being. None of the bifactor models yielded good model fit, even after excluding two items with low factor loadings and including a method factor for reverse-keyed items. Based on a shortened 22-item SIFS version, models suggested that the g-factor explained 52.9-59.6% of the common variance and that the SIFS sum score measured the g-factor with a reliability of .68-.81. Even though the SIFS sum score showed large test-retest reliability and correlated strongly with well-established self-report questionnaires and interviews, the lack of structural validity appears to be a serious disadvantage of the SIFS compared to existing self-reports questionnaires of personality functioning.

[The alternative model of personality disorders among the French population: Assessment with brief tools]. L'ENCEPHALE 2023; 49:496-503.

Abstract
OBJECTIVES The aim of this work was to study whether the French versions of the brief tools available to clinicians within the framework of the Alternative Model of Personality Disorders (AMPD) can account for the risks of personality disorders in the general population. Tools are available to accurately investigate either the Level of Personality Functioning (LPF) or the Pathological Personality Dimensions (PPD) which in turn allow the validation of the relevance of the AMPD for its criteria A and B. As these tools, such as Morey's Level of Personality Functioning Scale Self Rated (LPFS-SR) for Criteria A or the Personality Inventory for DSM-5 (PID5) by Krueger et al. for Criteria B, are lengthy, the question arises as to the use of the short tools derived from them. METHOD Data was collected from a sample of 433 people recruited on a volunteer basis with a complete protocol. The sample was predominantly female (83% female, 16% male, 2 people who did not wish to report their gender) and rather young (67% were 18-24 years old). The short version, the LPFS- BF of Hutsbaut et al., which we used in this work allows, as confirmed by several works, to consider on the basis of 12 items the global level of personality functioning. In order to assess the pathological dimensions of personality (PPD), we chose the short version of the Personality Inventory for DSM 5 (PID 5 BF) by Krueger et al. and used its validated French translation that satisfies the factor composition of the original version: Negative Affectivity, Antagonism, Detachment, Disinhibition and Psychoticism. To assess the intensity of personality disorders we used the dedicated subscale (Items 19 and 20) that the DSM 5 proposes in its Cross-Cutting Symptoms Measures of Level 1, in its French translation. A score higher than 2 was our Gold Standard when we tested the metric capacity of the two questionnaires to evaluate the A Criteria and then the B Criteria of the AMPD. RESULTS The overall results (Table 1) show levels that place the group in a non-clinical level. In terms of the severity of personality disorders it can be seen that 27 % are at risk of personality disorder (PDs>2). Comparing these two sub-groups (Table 1), we observed significant differences for all the factors studied, pointing towards a higher score for people at risk of PDs. A logistic regression analysis of the evaluation of persons at risk lead us to find that gender and age do not have a significant influence (p=0.225 and p=0.065 respectively) in a valid model (chi square=157, df=4, p<0.001) including the overall score on the LPFS (z=5.76, p<0.001) and the PID 5 (z=2.26, p<0.001). The Area Under the Curve (AUC=0.859) of this translation (Table 3) is consistent with the original version (AUC=0.84). It has metrological qualities (Sn=73.91%, Sp=85.33%, LR+=5.1, LR-=0.3005) that allowed us to use a threshold of 24 as a discriminant of a risk of moderate or severe personality disorder. In addition, if we followed the AMPD and considered the threshold of 24 on the LFPS-BF to be a risk score for personality disorder, we could see (Fig. 2) that the scores on the PID 5 BF fairly well reflected the expected pattern with a large AUC (0.901). According to the AMPD, the cut-points for the dimensions that would evoke the presence of criteria B in the case of the presence of criterion A (LPFS-BF>24) could be either a score greater than 2 for Negative Affectivity, a score greater than 0.8 for Detachment, Antagonism and Disinhibition, or a score greater than 1.2 for Psychoticism (Table 4). DISCUSSION The translation of the LPFS-BF that we used in this work has sufficient qualities to assess situations at risk of personality disorders when higher than 24. Its consistency was good (=0.84), and its factor composition in two factors (Self and Interpersonal Relations) was equivalent to the original version. The use of PID5-BF could therefore be used as a complement to the screening of AMPD A criteria, with a 25 for cut-point. The evaluation of the AMPD B criteria with the PID5-BF seemed relevant in view of our results; each of the subscales seemed to be able to correctly evaluate (AUC) persons with an LPFS-BF score at risk. However, the risk thresholds need to be confirmed in further work because of the essential role that the dimensions play in the diagnosis of types of personality disorders.

Abstract
The Levels of Personality Functioning Questionnaire 12-18 (LoPF-Q 12-18) is the only self-report measure informed by the Level of Personality Functioning (Diagnostic and Statistical Manual of Mental Disorders [5th ed.; DSM-5; American Psychiatric Association, 2013]) Alternative Model of Personality Disorders developed for adolescents. The present investigation includes two studies evaluating the English LoPF-Q 12-18. In Study 1, single-factor and bifactor structures (unidimensional severity criterion and four specific factors: identity, self-direction, empathy, intimacy) were evaluated in an ethnically diverse community sample (N = 453; age 10-18; 57% female). Study 2 used a community control (n = 298; age 10-18; 54.4% female) and clinical sample (n = 94; age 11-18; 58.5% female) to examine reliability, validity, and clinical utility. Study 1 results supported the bifactor model, with a robust general factor and little multidimensionality caused by the group factors, suggesting an essentially unidimensional structure. Study 2 revealed good internal consistency and construct validity and provided clinical cut-offs, supporting the use of the LoPF-Q 12-18 total score in research and clinical applications.

Social phobia and evasiveness: trial protocol for a randomized controlled feasibility and superiority trial of the effect of Modified Collaborative Assessment vs. standard assessment on patients' readiness for psychotherapy (CO-ASSM-RCT). Pilot Feasibility Stud 2023; 9:102. [PMID: 37340450 DOI: 10.1186/s40814-023-01332-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Accepted: 05/26/2023] [Indexed: 06/22/2023] Open
Abstract
BACKGROUND Evasive personality disorder (AvPD) and social phobia (SP) have substantial costs for patients and their families and great economic costs to the society. While psychotherapy can be an efficacious treatment, many patients drop out during treatment. Increased knowledge on how to decrease dropout from psychotherapy is warranted, including how to increase a patient's readiness for psychotherapy. METHODS We describe a randomized controlled feasibility and superiority trial of 42 individuals with a clinical diagnosis of either SP or AvPD, who are to initiate psychotherapeutic treatment in Danish outpatient mental health services. They will be randomized in a 1:1 ratio to either assessment-as-usual and receive no further assessment or to a Modified Collaborative Assessment (MCA) provided as a pre-treatment intervention before psychotherapy initiation. MCA will include a battery of psychological tests designed to thoroughly assess the patients' psychopathology. The tests are administered in collaboration with the patient, including detailed oral and written feedback. We hypothesize that the intervention is feasible regarding patient's acceptance and adherence. We further hypothesize that patients randomized to MCA will reach higher levels of readiness for psychotherapy as assessed with the University of Rhode Island Change Assessment Scale (URICA). DISCUSSION This protocol assesses the feasibility, efficacy, acceptability, and safety of an intervention aimed at changing the readiness for participation in psychotherapy of patients with SP and AvPD. Results from this feasibility study could guide the development of future large-scale trials of MCA and procedures for MCA treatment fidelity assessment. TRIAL REGISTRATION NCT2021001.

Diagnostic accuracy of severity measures of ICD-11 and DSM-5 personality disorder: clarifying the clinical landscape with the most up-to-date evidence. Front Psychiatry 2023; 14:1209679. [PMID: 37324826 PMCID: PMC10265646 DOI: 10.3389/fpsyt.2023.1209679] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Accepted: 05/15/2023] [Indexed: 06/17/2023] Open
Abstract
With the implementation of new dimensional models of personality disorder (PD) in the DSM-5 and ICD-11, several investigators have developed and evaluated the psychometric properties of measures of severity. The diagnostic accuracy of these measures, an important cross-cultural metric that falls between validity and clinical utility, remains unclear. This study aimed to analyze and synthesize the diagnostic performance of the measures designed for both models. For this purpose, searches were carried out using three databases: Scopus, PubMed, and Web of Science. Studies that presented sensitivity and specificity parameters for cut-off points were selected. There were no restrictions on the age and gender of the participants nor on the reference standard used or the settings. Study quality and synthesis were assessed using QUADAS-2 and MetaDTA software, respectively. Twelve studies were eligible covering self-reported and clinician-rated measures based on the ICD-11 and DSM-5 PD severity models. A total of 66.7% of the studies showed a risk of bias in more than 2 domains. The 10th and 12th studies provided additional metrics, resulting in a total of 21 studies for evidence synthesis. Adequate overall sensitivity and specificity (Se = 0.84, Sp = 0.69) of these measures were obtained; however, the cross-cultural performance of specific cut-off points could not be assessed due to the paucity of studies on the same measure. Evidence suggests that patient selection processes should mainly be improved (avoid case-control design), use adequate reference standards, and avoid only reporting metrics for the optimal cut-off point.

Dimensional models of personality disorders: Challenges and opportunities. Front Psychiatry 2023; 14:1098452.

Abstract
Categorical models of personality disorders have been beneficial throughout psychiatric history, providing a mechanism for organizing and communicating research and treatment. However, the view that individuals with personality disorders are qualitatively distinct from the general population is no longer tenable. This perspective has amassed steady criticism, ranging from inconsequential to irreconcilable. In response, stronger evidence has been accumulated in support of a dimensional perspective that unifies normal and pathological personality on underlying trait continua. Contemporary nosology has largely shifted toward this dimensional perspective, yet broader adoption within public lexicon and routine clinical practice appears slow. This review focuses on challenges and the related opportunities of moving toward dimensional models in personality disorder research and practice. First, we highlight the need for ongoing development of a broader array of measurement methods, ideally facilitating multimethod assessments that reduce biases associated with any single methodology. These efforts should also include measurement across both poles of each trait, intensive longitudinal studies, and more deeply considering social desirability. Second, wider communication and training in dimensional approaches is needed for individuals working in mental health. This will require clear demonstrations of incremental treatment efficacy and structured public health rebates. Third, we should embrace cultural and geographic diversity, and investigate how unifying humanity may reduce the stigma and shame currently generated by arbitrarily labeling an individual's personality as normal or abnormal. This review aims to organize ongoing research efforts toward broader and routine usage of dimensional perspectives within research and clinical spaces.

Suicidal ideation among men during COVID-19: Examining the roles of loneliness, thwarted belongingness, and personality impairment. Scand J Psychol 2023. [PMID: 36744862 DOI: 10.1111/sjop.12904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 01/09/2023] [Accepted: 01/17/2023] [Indexed: 02/07/2023]
Abstract
Suicidal ideation (SI) is a known precursor to suicide among men. While loneliness and thwarted belongingness (TB) have been identified as key factors influencing SI, no study has reported on all three constructs to investigate whether loneliness is associated with SI by way of TB. Furthermore, it is not clear whether personality impairment has a moderating role on this process. The present study examined the impact of loneliness on SI among men and whether TB mediated this relationship. Additionally, the study investigated whether personality impairment (i.e., self-functioning, interpersonal functioning) moderated the relationship between loneliness and TB. Canadian men (N = 434) completed an online survey that included self-report assessments of the study constructs. Conditional process modeling was used to test the indirect effect of loneliness on SI via the mediating effect of TB. Findings indicated a significant association between loneliness and SI that was mediated by TB. Further, impairment in self-functioning moderated the relationship between loneliness and TB, indicating that the relationship was stronger among men with greater difficulties in self-functioning. The findings are important to consider within the COVID-19 context, as they point to the need to reduce the detrimental impacts of loneliness, thereby potentially mitigating male SI.

The joint hierarchical structure of psychopathology and dysfunctional personality domain indicators among community-dwelling adults. Personal Ment Health 2023; 17:3-19.

Abstract
To examine the hierarchical structure of psychopathology and dysfunctional personality domains, 2416 Italian community-dwelling adult volunteers were administered a set of psychometrically sound psychopathology measures and the Personality Inventory for DSM-5 Brief Form+ (PID-5-BF+). Parallel analysis, minimum average partial, and very simple structure results suggested that 1-6 principal components (PCs) should be retained. Goldberg's bass-ackwards model of the joint psychopathology measure and PID-5-BF+ ipsatized domain scale correlation matrix evidenced a hierarchical structure that was consistent with the working model proposed by the Hierarchical Taxonomy of Psychopathology (HiTOP) consortium. Hierarchical agglomerative cluster analysis around latent variables of the psychopathology indicators and PID-5-BF+ domain scales recovered four latent dimensions, which were akin to the corresponding bass-ackwards components and nicely reproduced the HiTOP Internalizing, Externalizing, Thought Disorder, and Eating Pathology dimensions.

Abstract
Numerous studies have questioned the reliability and validity of borderline personality disorder's (BPD) categorical conceptualization. DSM-5 Section III's alternative trait-based model of BPD may better capture borderline pathology, but aspects of its validity should be further established. Thus, the authors examined whether a latent BPD factor derived from Section III traits exhibits (1) familial aggregation among siblings and (2) association with constructs related to borderline pathology. The authors also tested whether gender moderated associations. A total of 498 community-recruited adults completed the Personality Inventory for DSM-5, a behavioral assessment of risk-taking, and reported their history of childhood maltreatment, substance use, nonsuicidal self-injury, and suicidal ideation. Familial aggregation was assessed among 232 sibling pairs. Siblings' BPD scores were significantly correlated and most external validators were significantly associated with BPD, with the exception of risk-taking. Results did not vary by gender. Findings further support the construct validity of Section III's BPD trait profile.

Psychometric evaluation of the Estonian version of the Semi-structured Interview for Personality Functioning DSM-5 (STiP-5.1). Borderline Personal Disord Emot Dysregul 2022; 9:28.

Abstract
BACKGROUND The DSM-5 Alternative Model for Personality Disorders introduced a dimensional perspective on personality disorders. The model assesses functioning in four domains: Identity, Self-Direction, Empathy, and Intimacy. This study evaluates the psychometric properties of the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1) in Estonian. METHOD The sample consists of 131 participants: 58 from the general population and 73 from a mixed clinical sample that is further divided into a mood and anxiety disorder sample and personality disorder sample. All participants completed the STiP-5.1 interview and the Level of Personality Functioning Scale-Brief Form (LPFS-BF 2.0). RESULTS The Estonian STiP-5.1 interview has good internal consistency (McDonald's ω between .94-.98) and high convergent validity (correlations with LPFS-BF 2.0 above .7). Interview scores successfully differentiated the general population from the mixed clinical sample (Cohen's d = 2.68), as well as patients with personality disorder from those without (Cohen's d = 1.76). The LPFS-BF 2.0 total score differentiates the general population sample from the mixed clinical sample (Cohen's d = 1.99) but not the personality disorder sample from other clinical sample participants. CONCLUSIONS The properties of the Estonian STiP-5.1 replicate those of other languages, and empirically support a unified personality functioning dimension that can be meaningfully thought of as reflecting impairments in self and interpersonal functioning. Findings of this study will be discussed in the light of the ongoing debate on the dimensionality of personality pathology and the use of self-report versus interview measures for assessing personality pathology.

Abstract
Personality disorders are psychological ailments with a major negative impact on patients, their families, and society in general, especially those of the dramatic and emotional type. Despite all the research, there is still no consensus on the best way to assess and treat them. Traditional assessment of personality disorders has focused on a limited number of psychological constructs or behaviors using structured interviews and questionnaires, without an integrated and holistic approach. We present a novel methodology for the study and assessment of personality disorders consisting in the development of a Bayesian network, whose parameters have been obtained by the Delphi method of consensus from a group of experts in the diagnosis and treatment of personality disorders. The result is a probabilistic graphical model that represents the psychological variables related to the personality disorders along with their relations and conditional probabilities, which allow identifying the symptoms with the highest diagnostic potential. This model can be used, among other applications, as a decision support system for the assessment and treatment of personality disorders of the dramatic or emotional cluster. In this paper, we discuss the need to validate this model in the clinical population along with its strengths and limitations.

Abstract
The Alternative DSM-5 Model for Personality Disorders (AMPD) retains six specific personality disorders (PDs) that can be diagnosed based on Criterion A level of impairment and Criterion B maladaptive facets. Those specific diagnoses are still underresearched, despite the preference expressed by most PD scholars for a mixed/hybrid classification. This study explores the possibility of using Criterion A and B self-report questionnaires to extract the specific AMPD diagnoses. Plausible prevalence estimates were found in three samples (outpatient PD, private practice, community; N = 766) using the facet score ≥ 2 and t score > 65 methods for determining the presence of a Criterion B facet; diagnoses had meaningful correlations with external variables. This study provides evidence-albeit preliminary-that the extraction of the specific AMPD PDs from self-report questionnaires might be a viable avenue. Ultimately, it could promote the use and dissemination of those diagnoses for screening purposes in clinical and research settings.

Abstract
Researchers and clinicians are beginning to adopt dimensional approaches in the study and treatment of personality disorders (PD). Although dimensional approaches in the DSM-5 and ICD-11 hold considerable benefit, they need to better incorporate an appreciation of individuals' life stories, or narrative identities. Doing so will be necessary to flesh out the emphasis that both frameworks place on the role of identity in personality pathology. In this article, the authors review why, how, and when narrative identity theory and research can be integrated within dimensional approaches to PD. The authors describe established ways to assess narrative identity, review extant research on this construct in relation to PD, and signal areas crucial for future research. Stories lie at the heart of what it means to be human. The authors conclude that a greater consideration of the ways in which the self is storied can help further understanding and treatment of PD.

Abstract
Background and aims The COVID-19 pandemic has been accompanied by a worsening of mental health levels in some, while others manage to adapt or recover relatively quickly. Transdiagnostic factors such as personality functioning are thought to be involved in determining mental health outcomes. The present study focused on two constructs of personality functioning, Criterion A of the Alternative Model for Personality Disorders (AMPD, DSM-5) and mentalization, as predictors of depressive symptoms and life satisfaction during the COVID-19 pandemic. A second focus of the study was to examine whether this relationship was mediated by resilience. Methods Linear regression analyses were used to examine the relationship between personality functioning measured by Criterion A (AMPD, DSM-5) and mentalizing abilities as predictors, and depression and life satisfaction as mental health outcomes. To assess the hypothesis that this relationship is mediated by resilience a structural equation modeling approach was conducted. Data from N = 316 individuals from the general population were collected. Results Linear regression models revealed highly significant associations between Criterion A/mentalization and both outcome measures. Structural equation models showed a significant partial mediation by resilience of these relationships. Conclusion Our results support the hypothesis that mentalizing serves as a protective function by promoting resilience to the impact of stress and threats. Criterion A and mentalization performed similarly as predictors of mental health outcomes, providing empirically overlapping operationalizations of personality functioning. This finding emphasizes the importance of personality functioning in positive and negative mental health outcomes. Furthermore, our results are consistent with a mediating role of resilience.

Abstract
INTRODUCTION We propose that a dimensional, multilayered perspective is well suited to study maladaptive personality development in youth. Such a perspective can help understand pathways to personality pathology and contribute to its early detection. The research project 'APOLO' (a Dutch language acronym for Adolescents and their Personality Development: a Longitudinal Study) is designed based on McAdams' integrative three-layered model of personality development and assesses the interaction between dispositional traits, characteristic adaptations, the narrative identity and functioning. METHODS AND ANALYSIS APOLO is a longitudinal research project that takes place in two outpatient mental healthcare centres. Participants are youth between 12 years and 23 years and their parents. Data collection is set up to build a data set for scientific research, as well as to use the data for diagnostic assessment and systematic treatment evaluation of individual patients. Measurements are conducted half-yearly for a period of 3 years and consist of self-report and informant-report questionnaires and a semistructured interview. The included constructs fit the dimensional model of personality development: maladaptive personality traits (dispositional traits), social relations, stressful life events (characteristic adaptations), a turning point (narrative identity) and functioning (eg, achievement of youth specific milestones). Primary research questions will be analysed using structural equation modelling. ETHICS AND DISSEMINATION The results will contribute to our understanding of (the development of) personality pathology as a complex phenomenon in which both structural personality characteristics as well as unique individual adaptations and experiences play a role. Furthermore, results will give directions for early detection and timely interventions. This study has been approved by the ethical review committee of the Utrecht University Faculty for Social and Behavioural Sciences (FETC17-092). Data distribution will be anonymous and results will be disseminated via communication canals appropriate for diverse audiences. This includes both clinical and scientific conferences, papers published in national and international peer-reviewed journals and (social) media platforms.

Abstract
The Level of Personality Functioning Scale (LPFS) operationalizes Criterion A of the DSM-5 Alternative Model for Personality Disorders. Despite progress in LPFS measurement development and validation, there is a lack of research, and some disagreement, concerning structural, convergent, and incremental validity of LPFS self-report measures. The present study aimed to compare the LPFS Self-Report, LPFS Self-Report of Criterion A, and LPFS Brief Form. Internal structure was assessed through principal component analyses, factor analyses, and bifactor analyses of unidimensionality. Associations with both pathological and basic personality characteristics among the LPFS measures were explored. Incremental validity of LPFS severity in predicting pathological personality outcomes controlling for basic personality traits, and the reverse, were examined. Results suggest a unidimensional structure robustly associated with other pathological personality assessments. LPFS severity and basic personality traits mutually offered unique explanatory power. We discuss the implications of assessing personality pathology using LPFS self-report measures.

Abstract
Background Existing recommended treatment options for personality disorders (PDs) are extensive and costly. There is emerging evidence indicating that trauma-focused treatment using eye movement desensitization and reprocessing (EMDR) therapy aimed at resolving memories of individuals’ adverse events can be beneficial for this target group within a relatively short time frame. The primary purpose of the present study is to determine the effectiveness of EMDR therapy versus waiting list in reducing PD symptom severity. Furthermore, the effects of EMDR therapy on trauma symptom severity, loss of diagnosis, personal functioning, quality of life, and mental health outcomes will be determined. In addition, the cost-effectiveness of EMDR therapy in the treatment of PDs is investigated. Moreover, predictors of treatment success, symptom deterioration and treatment discontinuation will be assessed. Lastly, experiences with EMDR therapy will be explored. Method In total, 159 patients with a PD will be included in a large multicentre single-blind randomized controlled trial. The Structured Clinical Interview for DSM-5 Personality Disorders will be used to determine the presence of a PD. Participants will be allocated to either a treatment condition with EMDR therapy (ten biweekly 90-min sessions) or a waiting list. Three months after potential treatment with EMDR therapy, patients can receive treatment as usual for their PD. All participants are subject to single-blinded baseline, post-intervention and 3-, 6- and 12-month follow-up assessments. The primary outcome measures are the Assessment of DSM-IV Personality Disorders and the Clinician-Administered PTSD Scale for DSM-5. For cost-effectiveness, the Treatment Inventory of Costs in Patients with psychiatric disorders, EuroQol-5D-3L, and the Mental Health Quality of Life Questionnaire will be administered. The PTSD Checklist for DSM-5, Brief State Paranoia Checklist and Difficulties in Emotion Regulation Scale will be used to further index trauma symptom severity. Type of trauma is identified at baseline with the Childhood Trauma Questionnaire-SF and Life Events Checklist for the DSM-5. Personal functioning and health outcome are assessed with the Level of Personality Functioning Scale-BF 2.0, Outcome Questionnaire-45 and Mental Health Quality of Life Questionnaire. Experiences with EMDR therapy of patients in the EMDR therapy condition are explored with a semi-structured interview at post-intervention. Discussion It is expected that the results of this study will contribute to knowledge about the effectiveness, and cost-effectiveness of trauma-focused treatment using EMDR therapy in individuals diagnosed with a PD. Follow-up data provide documentation of long-term effects of EMDR therapy on various outcome variables, most importantly the reduction of PD symptom severity and loss of diagnoses.

Abstract
BACKGROUND The societal shutdown due to the Covid-19 pandemic involved mental health services for personality disorder (PD) and was introduced from 12 March 2020 in Norway. Rapid implementation of treatment modifications was required for patients typically characterized by insecure attachment and vulnerability to separation. AIM To investigate immediate reactions to the shutdown of services; alternative treatment received; and differences related to age in a clinical sample of patients with PD. DESIGN A survey performed from June to October 2020 (after the first Covid-19 wave) among 1120 patients from 12 units offering comprehensive group-based PD programs. RESULTS The response-rate was 12% (N = 133). Negative feelings of anxiety, sadness, and helplessness were noteworthy immediate reactions, but the dominating attitude was accommodation. Younger patients (<26 years) reported more skepticism and less relief. Modified treatment was mainly telephone therapy. Digital therapy was less available, but was more frequent among younger patients. A minority received digital group therapy. Most patients rated the frequency and quality of modified treatments as satisfactory in the given situation, but also worried about own treatment progress, lack of group therapy, and 47% missed seeing the therapist when having telephone consultations. CONCLUSION The survey confirms a radical modification from comprehensive group-based PD programs to telephone consultations, low availability of digital consultations and group treatments. Taking a short-term, first wave perspective, the survey indicates a noteworthy capacity among poorly functioning patients for accommodating to a clearly challenging situation, as well as considerable concern about treatment progress.

The relation between self-event connections and personality functioning in youth with severe psychopathology. J Pers 2021; 90:799-816. [PMID: 34932230 PMCID: PMC9543894 DOI: 10.1111/jopy.12697] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 11/17/2021] [Accepted: 12/07/2021] [Indexed: 11/29/2022]
Abstract
Objective One way in which individuals construct their narrative identity is by making self‐event connections, which are often linked to better functioning. Being unable to make connections is related to identity discontinuity and psychopathology. Work in the general population corroborates this association, but also highlights the importance of focusing on specific aspects of these connections and on vulnerable populations. Method We examined the association of self‐event connections with personality functioning in youth with severe psychopathology (cross‐sectional N = 228, Mage = 19.5, longitudinal N = 84), and the role of event and connection valence in the subsample of youth who made a connection (n = 188 and n = 68). Negative affectivity was controlled for in all models. Results We found no evidence that self‐event connections, nor connection valence and its interaction with event valence, are related to functioning. Positive event valence was associated with better functioning. Higher negative affectivity was strongly linked to lower functioning and explained the relation between event valence and functioning. No longitudinal associations emerged. Conclusions These findings show that for youth with severe psychopathology making self‐event connections may not be associated with better functioning. Moreover, negative affectivity may be a distal predictor of both event valence and functioning.

Abstract
OBJECTIVES A diagnostic system that fails to deliver clinically useful information will not be utilized and consequently will be unable to provide valuable data for health policy and clinical decision making. Therefore, it is imperative to obtain an accurate depiction of the clinical utility of the eleventh revision of the International Classification of Diseases (ICD-11) Personality Disorder (PD) model. The current mixed-methods systematic review aimed to determine the clinical utility of the ICD-11 PD classification system. METHOD An electronic screening of six databases was conducted and resulting studies were subjected to specific exclusion criteria, which elicited eight studies of interest. Study characteristics were tabulated and methodological quality was appraised. RESULTS Four studies offered strong support for the model's clinical utility, three offered some support accompanied by notable limitations and one study could only offer criticisms. CONCLUSION Future investigation of the ICD-11 PD classification system's (a) communicative value between clinicians and their patients, and between clinicians and their patient's families; (b) ease of use; and (c) feasibility in terms of practical application is required to achieve a complete understanding of its clinical utility and ultimately bring clarity to the current ambiguous findings.

Abstract
BACKGROUND Relational and emotional problems, dysregulation, self-harming or substance abuse often characterize personality disorders (PD). In Norway, COVID-19 restrictions led to an abrupt shutdown of services from 12 March 2020 also including specialized PD treatments. AIMS The objective of this study was to investigate social and mental distress among patients with PDs during the first COVID-19 wave. DESIGN A survey was distributed after the first COVID-19 wave (June-October 2020) among 1120 patients from 12 PD treatment units. RESULTS The response rate was 12% (N = 133). The survey reflected impairment of occupational activity (53% <50% activity last 6 months), life quality (EQ-5D-VAS: 56, SD 19), and personality functioning (LPFS-BF ≥12: 81%, 35% avoidant PD, 44% borderline PD) and high levels of depression and anxiety (PHQ-9 ≥ 10: 84%, GAD-7 ≥ 10: 68%), 49% with health-related anxiety. Problem increase was reported for anxiety (28%), depression (24%), aggression (23%), substance use (14%), and 70% of parents had more child-care difficulties. Self-destructive behaviors (26%) did not increase. The majority (78%) reported increased or unchanged social isolation and loneliness. Occupational activity declined with negative effects on part-time jobs/rehabilitation. Therapist contact was mainly telephone-based (63% ≥ weekly contact). More severe personality problems, current depressive symptoms, and self-harming before 12 March were associated with more frequent consultations. CONCLUSION The survey confirms severe, enhanced levels of mental distress among patients receiving telephone-based consultations as the main alternative to specialized PD treatment during the COVID-19 shutdown. The most vulnerable patients received more frequent consultations and self-destructive actions did not increase.

Abstract
The DSM-5 Alternative Model for Personality Disorders introduced a dimensional perspective on personality disorders and their assessment by measuring personality functioning in the following domains: Identity, Self-Direction, Empathy, and Intimacy. This study provides a replication of the psychometric evaluation of the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1) within a mixed clinical sample and a community sample. The sample consisted of 188 adults: 86 participants from the general population and 102 people from a mixed clinical sample. All participants completed the STiP-5.1 and Level of Personality Functioning Scale-Brief Form (LPFS-BF 2.0). Results showed good internal consistency (McDonald's ω = 0.89-0.94) and promising convergent validity (correlations with LPFS-BF 2.0 above 0.6) of the STiP-5.1. Its scores differentiated participants within the community sample from those in the mixed clinical sample with large effect sizes (rrb = 0.77-0.88). Moreover, the impairment in personality functioning was more pronounced in people with personality disorders than in other psychiatric disorders (medium effect size, rrb = 0.46-0.57), supporting the notion of a continuum of personality functioning impairment. The STiP-5.1 therefore offers an instrument with satisfactory psychometric properties for the assessment of personality functioning both for research and clinical practice.

Abstract
PURPOSE OF REVIEW The concept of personality functioning (Alternative DSM-5 Model of Personality Disorders) has led to increased interest in dimensional personality disorder diagnosis. While differing markedly from the current categorical classification, it is closely related to the psychodynamic concepts of personality structure and personality organization. In this review, the three dimensional approaches, their underlying models, and common instruments are introduced, and empirical studies on similarities and differences between the concepts and the categorical classification are summarized. Additionally, a case example illustrates the clinical application. RECENT FINDINGS Numerous studies demonstrate the broad empirical basis, validated assessment instruments and clinical usefulness of the dimensional concepts. Their advantages compared to the categorical approach, but also the respective differences, have been demonstrated empirically, in line with clinical observations. Evidence supports the three dimensional concepts, which share conceptual overlap, but also entail unique aspects of personality pathology, respectively.

Abstract
PURPOSE The purpose of the article is to present standard set of outcomes for people with personality disorder (PD), in order to facilitate patient outcome measurement worldwide. METHODS The International Consortium for Health Outcomes Measurement (ICHOM) gathered a multidisciplinary international working group, consisting of 16 experts, including clinicians, nurses, psychologists, methodologists and patient representatives, to develop a standard set of outcome measures for people with PD. The Delphi method was used to reach consensus on the scope of the set, outcome domains, outcome measures, case-mix variables and time points for measuring outcomes in service users. For each phase, a project team prepared materials based on systematic literature reviews and consultations with experts. RESULTS The working group decided to include PD, as defined by International Classification of Diseases 11th revision (ICD-11). Eleven core outcomes and three optional outcomes across four health domains (mental health, behaviour, functioning and recovery) were defined as those relevant for people with PD. Validated measures for the selected outcomes were selected, some covering more than one outcome. Case-mix variables were aligned to other ICHOM mental health standard sets and consisted of demographic factors and those related to the treatment that people received. The group recommended that most outcomes are measured at baseline and annually. CONCLUSION The international minimum standard set of outcomes has the potential to improve clinical decision making through systematic measurement and comparability. This will be key in improving the standard of health care for people with PD across the world.

Assessment of ICD-11 Personality Disorder Severity in Forensic Patients Using the Semi-structured Interview for Personality Functioning DSM-5 (STiP-5.1): Preliminary Findings.

Abstract
In forensic settings, several challenges may affect reliability of assessment of personality pathology, specifically when based upon self-report. This study investigates the Semi-Structured Interview for DSM-5 Personality Functioning (STiP-5.1) to assess level of severity of personality functioning in incarcerated patients. Thirty inpatients of three forensic psychiatric facilities completed the STiP 5.1 and additionally completed self-report questionnaires assessing symptom severity, personality functioning and traits. Staff members completed informant versions of personality functioning questionnaires. Previously assessed community (N = 18) and clinical samples (N = 80) were used as a reference. Interrater reliability and internal consistency of the STiP 5.1 were good. As expected, no associations were found between self-report and expert-ratings (STiP 5.1) of personality functioning. Remarkably, no associations were found between informant rated personality functioning and the STiP 5.1. This study confirms the discrepancies between self-report and expert-ratings in forensic settings and identifies the need to design and test assessment instruments within this context instead of generalizing findings obtained in regular mental health care samples. The STiP-5.1 may be a candidate for use in forensic samples, particularly to guide treatment planning and individual patient policy, although it remains unclear what specific information it offers above and beyond self-report and informant-report.

Abstract
The Alternative DSM-5 Model of Personality Disorders describes the level of personality functioning, defined by impairments in self functioning (self pathology) and problems in interpersonal functioning (interpersonal pathology), as the core feature of all personality disorders. A brief self-report measure to assess the level of personality functioning, the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF) comprising 12 items, was developed by a Dutch work group. The present study aimed at a first and comprehensive psychometric evaluation of the German version of the LPFS-BF in a large and representative general population sample (n=2470) as well as a non-clinical sample (n=849), particularly focusing on the factor structure, convergent validity and norm values. Confirmatory factor analyses revealed that the theoretically assumed and for the original version empirically confirmed two-factor solution was replicated in both samples with acceptable fit. Reliability of the total scale as well as both subscales (defined by the internal consistency) was high in both samples (McDonalds ω ≥0.83). Satisfactory convergent validity was indicated by high correlations of the German version of the LPFS-BF with other measures assessing personality dysfunction (r ≥0.72). The association with current psychological distress was similarly high. In the general population sample, the mean norm value (T50) of the total scale was 15 and T70 was 33. Although psychometric evaluations of the German LPFS-BF in patients with mental disorders, particularly those with personality disorders, have not yet been performed, this measure can be recommended as it provides a quick and user-friendly impression of the severity of personality functioning in the domains of self and interpersonal pathology.

Personality Functioning and Mentalizing in Patients With Subthreshold or Diagnosed Borderline Personality Disorder: Implications for ICD-11. Front Psychiatry 2021; 12:634332.

Abstract
The 11th revision of the International Classification of Diseases for Mortality and Morbidity Statistics (ICD-11) defines personality disorder according to personality functioning, which relates to self- and interpersonal functioning. The aim of the present study was to assess the relationship between mentalizing and personality functioning in patients with subthreshold or diagnosed borderline personality disorder. A total of 116 eligible participants were included. Mentalizing was assessed using the Mentalization Questionnaire (MZQ), personality functioning (self- and interpersonal functioning) was assessed using the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF), and borderline severity was assessed using the Zanarini Rating Scale (ZAN-BPD). Mediation analysis was employed to test if mentalizing accounted for the relationship between borderline severity and self- and interpersonal functioning. We found a significant relationship between borderline severity and both subscales of the LPFS-BF. Mentalizing fully and significantly mediated the relationship between borderline severity and interpersonal functioning. However, mentalizing only partly mediated the relationship between borderline severity and self-functioning. Controlling for the covariates gender and age did not impact the results. Mentalizing is likely to be involved in the ICD-11 model of personality functioning, especially interpersonal functioning. This could emphasize the relevance of therapy aimed at strengthening mentalizing abilities when treating personality pathology in general and people with borderline personality disorder in particular. However, self-functioning may be more nuanced, as aspects other than mentalizing also influence self-functioning. The study is explorative in nature and has methodological limitations that require caution in the interpretation and generalizability.

A Proposed Classification of ICD-11 Severity Degrees of Personality Pathology Using the Self and Interpersonal Functioning Scale. Front Psychiatry 2021; 12:628057.

Abstract
Background: The 11th version of the World Health Organization's International Classification of Diseases (ICD-11) has adopted a dimensional approach to personality disorder (PD) nosology. Notably, it includes an assessment of PD degree of severity, which can be classified according to five categories. To date, there is no gold standard measure for assessing degree of PD severity based on the ICD-11 model, and there are no empirically-based anchor points to delineate the proposed categories. With the operationalization of PD degrees of severity in the ICD-11 PD model now being closely aligned with Criterion A of the DSM-5 Alternative Model for Personality Disorders (AMPD), sharing a focus on self and interpersonal dysfunction, self-report instruments developed for the latter model might prove useful as screening tools to determine degrees of severity in the former. Methods: The Self and Interpersonal Functioning Scale, a brief validated self-report questionnaire originally designed to assess level of personality pathology according to the AMPD framework, was used to derive anchor points to delineate the five severity degrees from the ICD-11 PD model. Data from five clinical and non-clinical samples (total N = 2,240) allowed identifying anchor points for classification, based on Receiver Operating Characteristic curve analysis, Latent Class Analysis, and data distribution statistics. Categories were validated using multiple indices pertaining to externalizing and internalizing symptoms relevant to PD. Results: Analyses yielded the following anchor points for PD degrees of severity: No PD = 0-1.04; Personality Difficulty = 1.05-1.29; Mild PD = 1.30-1.89; Moderate PD = 1.90-2.49; and Severe PD = 2.50 and above. A clear gradient of severity across the five categories was observed in all samples. A high number of significant contrasts among PD categories were also observed on external variables, consistent with the ICD-11 PD degree of severity operationalization. Conclusions: The present study provides potentially useful guidelines to determine severity of personality pathology based on the ICD-11 model. The use of a brief self-report questionnaire as a screening tool for assessing PD degrees of severity should be seen as a time-efficient support for clinical decision and treatment planning.

Abstract
PURPOSE OF REVIEW The current review provides an examination of the levels of personality functioning outlined by the International Classification of Diseases-11 and the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. RECENT FINDINGS Across self-report measures, high convergence is observed, and they evince relatively robust relations with general and pathological traits as well as other clinical symptoms. At the same time, current measures of impairment also demonstrate unstable factor structures, poor discriminant validity (when measures offer subscales aligned with different forms of personality impairment), and tend to account for relatively little unique variance beyond traits. As a result, some have questioned the utility of personality impairment, as currently measured. SUMMARY The dimensional models of personality psychopathology included in the International Classification of Diseases-11 and 5th edition of the Diagnostic and Statistical Manual of Mental Disorders signify important steps toward an empirically supported and clinically useful diagnostic model; however, self-report measures of impairment are problematic. The authors conclude by calling for the refinement of these measures to more directly assess deficits in various domains of functioning as well as the dimensional models, by assessing traits first, and then examining the nature of the associated personality impairment.

Abstract
Level of Personality Functioning (LPF) represents the entry criterion (Criterion A) of the Alternative Model for Personality Disorders (AMPD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). It is defined as a dimensional general severity criterion common to all personality disorders and conceptually independent of personality types or traits, and it represents maladaptive self (identity and self-direction) and interpersonal (empathy and intimacy) functioning. We review the history, measurement, and significance of LPF. We show that the inclusion of LPF in the AMPD is well justified if it is defined as a general adaptive failure of a subjective intrapsychic system needed to fulfill adult life tasks. If so defined, LPF distinguishes itself from maladaptive traits (Criterion B of the AMPD) and captures the contribution humans make as agentic authors to the interpretation and management of the self. While Criterion B maladaptive traits provide important descriptive nuance to manifestations of personality pathology, maladaptive LPF is conditional to the diagnosis of personality disorder.

Abstract
To evaluate the reliability and convergent validity of the Structured Clinical Interview for DSM-5 Alternative Model for Personality Disorders (SCID-5-AMPD) Module I and Module II, 88 adult psychotherapy participants were administered the Italian translations of the SCID-5-AMPD Module I and Module II, Level of Personality Functioning Scale-Brief Form (LPFS-BF), Level of Personality Functioning Scale-Self Report (LPFS-SF), Personality Inventory for DSM-5 (PID-5), Personality Diagnostic Questionnaire-4+ (PDQ-4+), and Structured Clinical Interview for DSM-5 Personality Disorders (SCID-5-PD) relying on a Williams crossover design. SCID-5-AMPD Module I and Module II showed excellent inter-rater reliability. In terms of convergent validity, meaningful associations were observed between SCID-5-AMPD Module I scores and self-report measures of Criterion A; similarly, SCID-5-AMPD Module II trait scores were meaningfully related to PID-5 trait scores. As a whole, our preliminary findings supported the clinical utility of DSM-5 AMPD.

Abstract
To evaluate the relationships between body dysmorphic disorder (BDD) and Alternative DSM-5 Model for Personality Disorder (AMPD) criterion A and dysfunctional personality trait (i.e., criterion B) measures, 420 Italian community-dwelling women were administered three measures of BDD (i.e., the Body Dysmorphic Disorder Questionnaire, the Body Dysmorphic Disorder-Dimensional Scale, and the Appearance Anxiety Inventory), as well as the Level of Personality Functioning Scale-Brief Form (LPFS-BF) and the Personality Inventory for DSM-5-Short Form (PID-5-SF). The three BDD measures showed substantial convergent validity correlations and could be reliably cumulated to obtain the BDD Cumulative Index (BDDCI). Several significant, nonnegligible correlations were observed between the BDDCI as well as the LPFS-BF scale scores and PID-5-SF personality trait scale scores. Relative importance weight analysis results showed that LPFS-BF scale scores and PID-5-SF trait scale scores were substantial predictors of the BDDCI scores (R = 0.42, f = 0.72). In particular, AMPD criterion A impairment in self-functioning and AMPD criterion B depressivity, anhedonia, perseveration, separation insecurity, and cognitive and perceptual dysregulation were core components of the dysfunctional personality profile associated with BDD.

Abstract
Recent developments in the dimensional assessment of personality functioning have made the implementation of latent measurement models increasingly attractive. In this study, we applied item response theory (IRT) to a well-established personality functioning instrument (the OPD Structure Questionnaire) to identify a unidimensional latent trait and to evaluate the feasibility of computer adaptive testing (CAT). We hypothesized that the use of IRT could reduce the test burden - compared to a fixed short form - while maintaining high precision over a wide range of the latent trait. The OPD-SQ was collected from 1235 patients in a psychosomatic clinic. IRT assumptions were fulfilled. A 9-factor model yielded sufficient fit and unidimensionality in exploratory factor analysis with bifactor rotation. Items were iteratively reduced, and a graded-response IRT model was fitted to the data. Simulations showed that a CAT with approximately 7 items was able to capture an OPD-SQ global severity score with an accuracy similar to that of a fixed 12-item short form. The final item bank and CAT yielded satisfactory content validity. Strong correlations with depression and anxiety replicated previous results on the OPD-SQ. We concluded that IRT applications could be useful to reduce the test burden of personality functioning instruments.

Abstract
The diagnostic concept of Personality Disorder (PD) is changing. A dimensional PD concept that focuses on severity of impairment of personality functioning was introduced in the DSM 5 Section III in 2013 and is adopted by the upcoming ICD-11 in a similar manner. Several reliable, valid and useful instruments to assess personality functioning (Criterion A) either as self-report, expert rating or clinical interview were developed in the past years. This article gives a latest state-of-the-art overview of these measures. It underlines the importance of multi-informant multi-method assessment of, and a longitudinal perspective on PD pathology and the importance of standardized inclusion of PD individuals in studies to increase the significance of research findings.

Abstract
The goal of this study was to test in a clinical sample the interrater reliability and convergent validity of the Differentiation-Relatedness Scale (D-RS), a measure that evaluates mental representations based on open-ended descriptions of self and significant others. The study also investigated the ability of the D-RS to predict personality disorders (PDs) from Section II of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and the dysfunctional trait domains presented in the Alternative DSM-5 Model for Personality Disorders Criterion B in Section III of the DSM-5. We also evaluated if the D-RS predicts observed Section II PDs over and above Criterion B of the Alternative DSM-5 Model for Personality Disorders. We found that the interrater reliability of the D-RS was good on the basis of the mean scores of 6 independent raters and that it showed moderate convergent validity. Results of dominance analyses indicated that the D-RS is a significant predictor of Section II borderline PD and of the overall number of DSM-5 PDs. When we considered the Section III Criterion B for PDs, the D-RS was not able to predict any of the Personality Inventory for DSM-5 domains, suggesting that the D-RS may be more related to personality functioning behind mental representations than to maladaptive personality traits. Finally, results of hierarchical regression analyses suggested that the D-RS produced a significant but modest increase in the prediction of borderline PD traits and the overall number of PDs traits even when the effect of the Personality Inventory for DSM-5 domains were controlled for.
