Despite evidence for the intergenerational transmission of borderline personality disorder (BPD) pathology from mothers to offspring, the factors underlying the relation between mother and child BPD symptoms remain unclear and little is known about the pathways through which maternal BPD symptoms may relate to BPD symptoms in their offspring. One set of factors that warrants consideration in this regard is mother and child emotion regulation (ER) difficulties. In particular, theory and research suggest an indirect relation between mother and child BPD symptoms through maternal ER difficulties (and related maladaptive emotion socialization strategies) and, subsequently, child ER difficulties. Thus, this study used structural equation modeling to examine a model wherein maternal BPD symptoms relate to offspring BPD symptoms in adolescence through maternal ER difficulties (and maladaptive maternal emotion socialization strategies) and, subsequently, adolescent ER difficulties. A nationwide community sample of 200 mother-adolescent dyads completed an online study. Results provided support for the proposed model, revealing both a direct relation between maternal and adolescent BPD symptoms and two indirect relations through (a) maternal and adolescent ER difficulties and (b) maternal ER difficulties, maternal maladaptive emotion socialization strategies, and adolescent ER difficulties. Results highlight the relevance of both mother and adolescent ER difficulties in the relation between mother and offspring BPD pathology, as well as the potential clinical utility of targeting mother and child ER in interventions aimed at preventing the intergenerational transmission of BPD pathology.

The Personality Inventory for the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fifth Edition (PID-5) was developed as a measure of the traits included in the alternative model of personality disorders (AMPD) in Section III of the DSM. The PID-5 is composed of 25 scales measuring each trait in the AMPD across five domains: negative affectivity, detachment, disinhibition, antagonism, and psychoticism. Previous research suggests that there may be important differences in the expression of personality pathology across race and culture, particularly between people with eastern and western cultural heritages. The goal of the current research was to examine the measurement invariance of the PID-5 across these groups. In the current study, 865 young men and women who identified as White, East Asian, or Southeast Asian completed the PID-5 and international personality item pool (IPIP). On the domain level, a multigroup exploratory structural equation model found that the PID-5 had configural and metric invariance, but lacked complete scalar invariance. On an item level, all scales had configural invariance, one lacked metric invariance, and 11 of the 25 scales lacked scalar invariance across race. For the invariant scales, East and Southeast Asians tended to have higher mean scores than White participants. The PID-5 scales had similar relations with IPIP scales across groups. These results suggest that the PID-5 scales are measuring similar constructs across groups on a global, structural level, but that mean scores may represent different levels of latent personality pathology across groups. The PID-5 may be confidently used in these groups, but mean comparisons should be interpreted with caution. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Narrative identity, as an integral element of personality, has gained increased attention for understanding personality pathology. In this study, associations between narrative identity characteristics (i.e., event valence, theme, contextual coherence, thematic coherence, self-event connection valence, agency, and communion) and personality pathology were examined. Personality pathology was conceptualized as (a) levels of personality (dys)functioning and maladaptive personality traits, (b) six trait facet profiles, and (c) categorical DSM-5 (fifth edition of the Diagnostic Statistical Manual of Mental Disorders) diagnoses. Data of 242 youth (M_age = 18.79; SD_age = 2.65) were collected as part of a longitudinal study on personality development. Narratives were assessed with turning point interviews, and trait and functioning levels with self-report questionnaires. The narrative identity characteristics of a negative valence, a negative self-event connection valence, low agency, and low communion were associated with higher levels of personality dysfunctioning, negative affectivity, detachment, and psychoticism. These characteristics were also associated with the borderline, avoidant, obsessive-compulsive, and schizotypal trait facet profiles. No associations were found when considering personality pathology from a categorical perspective. Findings may inspire researchers and clinicians to give personal stories a more central role in their work. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The present study sought to examine the relation between borderline personality disorder (BPD) symptoms and empathic accuracy while improving on prior methodologies by using daily affect assessment in romantic partners. BPD symptoms were assessed in both members of 81 community couples who also reported on their own and their partner's negative and positive affect daily for 3 weeks. Data were analyzed using the Truth and Bias Model of Judgment, which allows the source of empathic accuracy to be parsed into partner affect (truth) and own affect (bias). Results provided evidence that individuals with higher BPD symptoms exhibited increased empathic accuracy for a partner's negative affect, particularly when partners also had higher BPD symptoms. The source of this accuracy stemmed more from bias forces than truth forces, indicating that participants' own affective states lead to more accurate judgments of partner affective state. The results suggest that this bias reduced the general tendency among participants to underestimate partner negative affect, thus leading to higher empathic accuracy. Overall, our results extend and provide support for previous research indicating that BPD symptoms are associated with heightened, not diminished, empathic accuracy.

Borderline personality disorder (BPD) is a serious and understudied mental health condition associated with profound personal and public health consequences. Methodological differences in characterizing BPD may limit understanding the scope of the disorder's prevalence and effect. For example, using different diagnostic rules for BPD can affect apparent prevalence, comorbidity, and clinical presentation. This study examined how differences in diagnostic rules used to assign BPD diagnosis impacted its prevalence and associations with clinically relevant variables (e.g., demographics, comorbidity, treatment-seeking). Participants were a nationally representative sample of 36,309 noninstitutionalized U.S. adults. All variables were assessed via clinical interview (Alcohol Use Disorder and Associated Disabilities Interview Schedule-5). Six diagnostic rules determined BPD status. We used frequencies to examine prevalence rates of and associations between BPD and other clinical variables, and logistic regressions to examine the associations between each BPD variable and the other outcomes. The prevalence of BPD ranged widely-from 0.5% to 11.4%-per the diagnostic rule used. Associations between BPD diagnosis and various outcomes and clinical variables generally remained stable across all diagnostic rules, though effects became more extreme as diagnostic rules became more restrictive. Additionally, meaningful differences emerged as a function of the number of items used (30 vs. 18 items) even with no other changes to diagnostic rules. The field examining BPD and associated problem behaviors should critically consider how to most effectively characterize BPD to understand these problems more accurately and optimize the generalizability of findings.

The fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5; American Psychiatric Association, 2013) introduced the clinician-rated Levels of Personality Functioning Scale (LPFS) as an indicator of general personality functioning based on four elements: Identity, Self-Direction, Empathy, and Intimacy. Construct validation strategies were employed to select and evaluate items from the Personality Assessment Inventory (PAI; Morey, 2007) to measure the four elements of the LPFS. In Study 1, conceptual ratings of PAI items produced lists of candidate items for the four elements. In Study 2, a sample of student respondents (n = 312) was used to select the final items for the PAI-Levels of Personality Functioning (PAI-LPF). In Study 3, a large sample of adults (n = 505) gathered using Amazon's Mechanical Turk was used to cross-validate the psychometric properties of the PAI-LPF element scales. Means, standard deviations, and coefficient alpha values are reported for the PAI-LPF total score and element scales using the PAI community adult and clinical patient normative samples. The PAI-LPF offers clinicians and researchers the ability to include the LPFS as part of a comprehensive assessment of personality and psychopathology offered by the PAI.

Borderline personality disorder (BPD) has been associated with a reduced functional flexibility of the autonomic nervous system (ANS), indexed by decreased vagally mediated heart rate variability (vmHRV). Employing a comprehensive Section II-based assessment approach and a partial Section III-based assessment approach (including Criterion A of the alternative model of personality disorders [AMPD]), the present study investigates how different conceptualizations of personality disorders (PDs) according to the Diagnostic and Statistical Manual for Mental Disorders, 5th edition relate to ANS function. Using the BPD section of the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II, a Section II-based assessment approach) and the Semistructured Interview for Personality Functioning DSM-5 (STiP-5.1, a Section III-based assessment approach), we conducted linear regression analyses to examine how categorical (BPD diagnosis) and dimensional (severity and domain) measures of PD are associated with ANS activity among adolescent psychiatric patients (N = 147, M_age = 15.25 years). Replicating earlier findings, analyses revealed a statistically significant positive association between the SCID-II measures of BPD and heart rate (HR), b = 0.43, t(59) = 3.57, p = .001, f = .57, as well as a statistically significant negative association between the SCID-II measures of BPD and vmHRV, b = -0.34, t(59) = -2.74, p = .008, f = .47. Neither the STiP-5.1 total score nor the subscales of the Level of Personality Functioning Scale (LPFS) were associated with HR or vmHRV. The present findings indicate that the SCID-II may capture features of PD that are more informative of variance in physiological function than the STiP-5.1.
