Abstract
The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5; American Psychiatric Association, 2013), includes 10 categorical personality disorders (PD) in Section II (Section II PD) and a dimensional alternative model of PD (AMPD) in Section III. We compared the two models in explaining concurrent psychosocial functioning levels in psychiatric outpatients and community residents screened as at risk for PD pathology (N = 600). The AMPD's fully dimensional form showed stronger associations with psychosocial difficulties and explained more of their variance compared with the categorical Section II PD. AMPD Criterion A (personality functioning impairment) and Criterion B (pathological traits) incrementally predicted psychosocial functioning about equally with some unique predictions. Finally, AMPD's six categorical PD diagnoses did not show stronger associations with psychosocial functioning than the corresponding Section II PD diagnoses. Findings directly comparing the two models remain important and timely for informing future conceptualizations of PD in the diagnostic system.

Convergence of the dimensional assessment of personality pathology (DAPP-BQ) and the five-factor personality inventory for the international classification of diseases 11th edition (FFiCD) in the context of the five-factor model and personality disorders. BMC Psychiatry 2024; 24:386.

Abstract
The current manuscript presents the convergence of the Dimensional Assessment of Personality Pathology (DAPP-BQ), using its short form the DAPP-90, and the Five-Factor Personality Inventory for International Classification of Diseases (ICD-11), the FFiCD, in the context of the five-factor personality model and the categorical approach of personality disorders (PDs). The current manuscript compares the predictive validity of both the FFiCD and the DAPP-90 regarding personality disorder scales and clusters. Results demonstrate a very high and meaningful convergence between the DAPP-90 and the FFiCD personality pathology models and a strong alignment with the FFM. The DAPP-90 and the FFiCD also present an almost identical predictive power of PDs. The DAPP-90 accounts for between 18% and 47%, and the FFiCD between 21% and 47% of PDs adjusted variance. It is concluded that both DAPP-90 and FFiCD questionnaires measure strongly similar pathological personality traits that could be described within the frame of the FFM. Additionally, both questionnaires predict a very similar percentage of the variance of personality disorders.

Abstract
The publication of the Alternative Model of Personality Disorder (AMPD) was a signpost achievement in the personality assessment. However, research on the AMPD has generally not led to either a deeper understanding of personality disorder or personality assessment or new ideas about how to provide better care for people with personality disorder diagnoses. A significant portion of research has focused on narrow issues and appears to be driven in part by ideological differences between scholars who prefer Criterion A (personality functioning) or Criterion B (maladaptive traits). I trace these issues to ambiguity about the concept of personality functioning as defined in the AMPD and its conceptual distinction from personality traits and problems in living. In this paper, I reground these concepts in coherent and distinct definitions, elaborate upon the implications of their differences, and show how these differences can help clarify and reorient AMPD research to focus on generating clinically useful models for personality pathology and personality assessment.

Abstract
Maternal personality plays a role in how a mother parents her children and adolescents. Current trait-based measures of personality are acceptable for use in maternal samples, but the presence or absence of given personality traits might not be enough to describe how personality relates to parenting. The Level of Personality Functioning Scale (LPFS) could serve as a solution, as it was designed to capture level of dysfunction in personality without being reliant on specific personality traits. Research, however, has yet to demonstrate the LPFS as a useful measure of personality in maternal samples, thus the goal of this study. A sample of 123 mothers reported on behavioral problems in their adolescent-aged children and their own personality using both a trait-based measure and the LPFS. Our data showed that maternal reports on the LPFS were associated with maternal perceptions of adolescent behavioral problems, in addition to being an acceptable measure of personality in our maternal sample. We also provide support for incremental validity of the LPFS in our sample, as the LPFS uniquely predicted maternal perceptions of adolescent behavioral problems even after controlling for maternal personality traits. Our results are discussed in light of the limitations of the extant work on maternal personality and add to the literature by demonstrating that the LPFS is an acceptable and ubiquitous measure of personality in maternal samples.

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.

Abstract
Personality functioning impairment is at the center of many dimensional models of personality. Available measures of personality functioning impairment are limited to self-report, clinician-/informant-rated, and interview methods. Although researchers have begun investigating established performance-based instruments' potential for assessing personality functioning impairment, administration and scoring of these instruments is complex and the latent variables they measure diverge from personality functioning impairment as described in the ICD-11 and the Alternative Model for Personality Disorders (AMPD) of the DSM. We address this absence by developing and psychometrically evaluating the Level of Personality Functioning Scale-Questionnaire-based Implicit Association Test (LPFS-qIAT). The LPFS-qIAT's psychometric properties were evaluated across four studies, producing initial evidence supporting the new instrument's reliability as well as its convergent, discriminant, and criterion-related validity. As the first performance-based measure of personality functioning impairment that aligns with the AMPD and, to a degree the ICD-11, that is easily administered, scored, and interpreted, the LPFS-qIAT shows potential to become a valuable tool in both research and clinical practice.

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 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.

Abstract
Personality disorders (PDs) are associated with interpersonal dysfunction, loneliness, and reduced social embeddedness. This study investigates loneliness and social network size in association with self- and clinician-rated personality functioning regarding the DSM-5's Alternative Model for Personality Disorders (AMPD). Eighty psychiatric inpatients including participants with and without PDs completed the Semi-structured Interview for Personality Functioning, the Level of Personality Functioning Scale - Brief Form, the UCLA Loneliness Scale, and the Social Network Index. Patients with PDs reported more loneliness and personality dysfunctioning than patients without PDs. Social network size did not differ between patient groups and showed lower correlations with personality functioning compared to loneliness. Loneliness was further associated with deficits in personality functioning. Deficits in distinct AMPD domains and loneliness may constitute transdiagnostically relevant factors that are related and mutually reinforcing. This could be important for identifying patients beyond PD diagnoses who are at risk of poor psychosocial functioning and require tailored psychotherapy.

Abstract
As developmental and clinical research on identity has largely developed in disconnect, scholars recommend adopting a developmental psychopathology perspective on identity, which considers adaptive and pathological identity functioning. Such a perspective has also been introduced in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) Alternative Model for Personality Disorders (AMPD), which suggests that all personality disorders (PDs) are marked by moderate to extreme deficits in self-functioning (i.e., identity and self-direction). The present study aims to validate the Dutch Self-Concept and Identity Measure (SCIM), a 27-item self-report questionnaire that assesses consolidated identity, disturbed identity, and lack of identity, in 153 psychiatric inpatients with PDs (75.2% female; Mage = 31.73). We investigated the factor structure and reliability of the SCIM, and examined associations of SCIM scales with typical identity processes, AMPD domains of self-functioning, and symptoms of all PDs. Results indicated that a 23-item Dutch SCIM produced valid and reliable scores among patients with PDs. Furthermore, SCIM scales were significantly and differentially related to identity commitment processes, ruminative identity exploration, domains of self-functioning, and symptoms of all PDs. Moreover, findings indicated that PDs varied regarding the severity of identity impairment.

Abstract
Many factors are implicated in developing and maintaining loneliness, including aspects of personality functioning and experience of early adverse childhood events. This study aimed to examine the relationship between domains of personality dysfunction, including self- and interpersonal functioning, and loneliness and determine whether such personality factors mediate the relationship between childhood parental indifference and loneliness. In total, 393 community-dwelling adults, mean age 34.3 (SD = 12.67), were recruited online for cross-sectional assessment of loneliness, personality functioning, big-five personality traits and perceived childhood parental indifference. Linear regression analyses were conducted followed by a parallel mediation model. Self- and interpersonal dysfunction were positively associated with loneliness and remained significant predictors of loneliness after controlling for five-factor personality traits. Impaired personality functioning accounted for 12% of loneliness variance. Finally, self-dysfunction mediated the relationship between childhood parental indifference and loneliness. Findings emphasize the importance of addressing personality functioning when developing psychosocial interventions aimed at tackling loneliness.

Abstract
Severity is the main component of the ICD-11 personality disorder (PD) classification, but pertinent instruments have only recently been developed. We analyzed the psychometric properties of the ICD-11 Personality Disorder Severity scale (PDS-ICD-11) in a mixed sample of 726 community and clinical subjects. We also examined how the different components of the ICD-11 PD system -five trait domains, the borderline pattern specifier, and severity, all of them measured through self-reports- are interconnected and operate together. PDS-ICD-11 properties were adequate and similar to those of the original instrument. However, regressions and factor analyses showed a considerable overlap of severity with the five personality domains and the borderline specifier (72.6%). Bifactor modeling resulted in a general factor of PD (g-PD) that was not equivalent to severity nor improved criterion validity. The whole ICD-11 PD system, i.e., five personality domains, borderline, and severity, explained an average of 43.6% of variance of external measures of well-being, disability, and clinical problems, with severity contributing 4.8%. Suggestions to further improve the ICD-11 PD taxonomy include remodeling the present definition of severity to give more weight to the real-life consequences of traits.
