Reliability and validity of the Chinese version of the Structured Interview of Personality Organization-Revised (STIPO-R).

With the publication of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, a set of dimensional criteria was added as an emerging alternative model to the diagnosis of personality disorder (PD; American Psychiatric Association, 2013). Parallel to this, within the object relations conceptualization of personality pathology, a structured interview, the Structured Interview of Personality Organization (STIPO), was developed to assess pathological personality and then revised (STIPO-R). In this study, the reliability and validity of the Chinese version of the STIPO-R were tested on a sample of 236 Chinese participants, including both psychiatric patients and healthy individuals. Overall, the STIPO-R showed good internal consistency, interrater and test-retest reliability, and generally satisfactory results in structure and convergent validity. The STIPO-R also demonstrated discriminant validity (healthy individuals vs. psychiatric patients with PD vs. psychiatric patients without PD). Results are also discussed in light of cultural differences between Chinese and Western cultures. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The allocation of patients with personality disorders to a suitable treatment approach: The development of a checklist based on patients' life stories.

Treatment assignment for patients with personality disorders (PDs) involves a complex process consisting of diagnostic assessment and deciding on the most appropriate psychotherapeutic treatment. This article describes the development of a checklist for systematic analysis of life stories to support reflective and transparent assignment of patients to either dialectical behavioral therapy (DBT) or schema-focused therapy (SFT). In a first study, an email survey, focus group, and member check were conducted among eight clinical experts to identify relevant dimensions in life stories in patients with PDs. In a second study, a checklist based on these dimensions was developed in three rounds of testing with nine clinical experts and nine psychology students. Checklist results were compared to actual assigned treatment for 20 patients. Systematic evaluation of life stories, is promising in supporting the allocation of patients with PDs to a suitable treatment approach by focusing on specific and consensual dimensions in patients' life stories.

The Utility of Neuromuscular Assessment to Identify ADHD Among Patients with a Complex Symptom Picture.

OBJECTIVE: Diagnostic assessment of ADHD is challenging due to comorbid psychopathologies and symptoms overlapping with other psychiatric disorders. In this study, we investigate if a distinct pattern of neuromuscular dysregulation previously reported in ADHD, can help identifying ADHD in psychiatric patients with diverse and complex symptoms. METHOD: We explored the impact of neuromuscular dysregulation, as measured by The Motor Function Neurologic Assessment (MFNU), on the likelihood of being diagnosed with ADHD, affective disorder, anxiety disorder, or personality disorder among adults (n = 115) referred to a psychiatric outpatient clinic. RESULTS: Logistic regression revealed that neuromuscular dysregulation was significantly associated with ADHD diagnosis only (OR 1.15, p < .01), and not with affective-, anxiety-, or personality disorders. Sensitivity and specificity for ADHD at different MFNU scores is provided. CONCLUSIONS: A test of neuromuscular dysregulation may promote diagnostic accuracy in differentiating ADHD from other psychiatric disorders in patients with an overlapping symptom picture. This may have important implications for clinical practice. More studies are needed.

Perception of stigma across diagnostic models of personality pathology.

Stigmatizing views surrounding mental illness are widespread. Personality disorders (PDs) are among the most stigmatized mental illnesses, as individuals with PDs are often described using pejorative terms, which might impact clinicians' a priori expectations and increase the likelihood of stigmatization, discrimination, or early termination from treatment. The degree to which the terms used in any diagnostic classification systems are stigmatizing has never been examined. The current study aims to explore the level of stigma perceived in diagnostic terms used and to compare which systems of classification (the Diagnostic and Statistical Manual of Mental Disorders, fifth edition [DSM-5] Section II, DSM-5 Alternative Model of Personality Disorder, and Hierarchical Taxonomy of Psychopathology [HiTOP]) are reported as less stigmatizing. The current study consisted of three samples. Individuals with lived experience of personality pathology (n = 218) completed an online survey examining the level of stigma perceived in diagnostic terms; mental health care providers (n = 75) and undergraduate psychology students (n = 732) also completed online surveys examining their perceptions of stigma within diagnostic terms. We examined differences in perceived stigma between the three classification systems across the three samples. Among mental health care providers, the HiTOP was rated as the least stigmatizing while DSM-5 categorical labels were rated as the most stigmatizing. There were no significant differences found among individuals with lived experience or undergraduate students. Understanding the degree to which the terms used to describe personality pathology contributes to reducing stigma has potentially important repercussions for research and clinical practice.

Genetic association of SLC6A3 (dopamine transporter) gene polymorphisms with personality disorders and substance abuse disorders: a systematic review and meta-analysis.

INTRODUCTION: Personality disorders (PD) are characterized by socially dysfunctional behavioral patterns that affect patients and show higher incidence rates within families. Substance abuse disorders (SAD) are exemplified by extensive and prolonged use of substances, including alcohol, nicotine, or illegal drugs. Genetic predisposition for both PD and SAD has been reported to involve gene variants regulating dopaminergic pathways. Yet, discrepancy among reported results necessitates further elucidation of potential hereditary-related risk factors. Because both disorders impose a societal burden, knowledge on the impact of certain genetic backgrounds on these diseases could help develop evidence-based strategies for efficacious treatment approaches. MATERIALS AND METHODS: In the present study a systematic review was performed, and the association between dopamine transporter gene polymorphism (SLC6A3), particularly rs28363170 entailing a 40-bp variable number tandem repeat, and PD as well as SAD was investigated recruiting meta-analysis approach. RESULTS: Initial literature search for PD yielded 1577, from which nine fulfilled eligibility criteria to be used in a meta-analysis including 729 cases and 2113 controls. From the 934 studies retrieved for SAD, only 29 articles with 5221 cases and 4822 controls were used for meta-analysis. A statistically significant association was seen between rs28363170 (for the 9-repeat allele) and PD in European populations according to the co-dominant mode of inheritance. For SAD no statistically significant correlation under any mode of inheritance was observed. There was no indication of time-trend phenomena. CONCLUSION: Our findings demonstrate the association of SLC6A3 gene polymorphism with PD, thus underling the need to understand neurobiological mechanisms inherent to the above disorders to guide treatment strategies under the perspective of personalized medicine.

A comparison of the associations of the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, Section II personality disorders and Section III personality domains with clinical dysfunction in a psychiatric patient sample.

In this study, we compare the incremental predictive capacities of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) Section II personality disorders (SII-PDs) with Section III trait domains of the Alternative Model of Personality Disorders (AMPD) in a psychiatric outpatient sample (N = 185). To this end, a series of hierarchical regression analyses was conducted in which the 10 SII-PDs and the five AMPD trait domains served as the predictor variables and five areas of clinical dysfunction as the criterion variables. Two models for each criterion were tested. In Model A, the 10 PDs were entered as a block, followed by the block entry of trait domains; in Model B, the block entry of these predictors was reversed. As the AMPD was designed to address the shortcomings of the SII-PDs, it was hypothesized that the AMPD trait domains would show greater predictive capacity vis-à-vis the latter by (a) explaining more overall variance for each criterion variables when entered first into the model versus when SII-PDs was entered first and (b) explaining more incremental variance than SII-PDs when block was entered second. These hypotheses were partially supported. Overall, the AMPD trait domains predicted more variance than SII-PDs and demonstrated better model fit and more predictive power for three of the criterion variables. Similarly, the AMPD domains predicted a significant but modest incremental increase in variance over that of the SII-PDs for three of the criterion variables. We conclude that more work needs to be done to improve the AMPD, particularly in the assessment of externalizing psychopathology as it relates to clinical dysfunction.

Head-to-head comparisons of Diagnostic and Statistical Manual of Mental Disorders, fifth edition, Section II and Section III personality disorder in predicting clinical outcomes.

In 2022, PDs: Theory, Research, and Treatment published a 10-year retrospective on the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), Section III, Alternative Model for PDs (AMPD; American Psychiatric Association, 2013). The articles of the 10-year retrospective provided evidence in support of the validity, reliability, and clinical utility of the AMPD. Specifically, it provided evidence in support of the unidimensional factor structure of the LPF and the five-dimensional structure of the pathological trait domains. In addition, evidence in support of the construct validity of the LPF in its association with psychiatric severity, functional outcomes, traditional PDs, cognitive, emotional, and contextual correlates, and other indices of maladaptive self- and interpersonal functioning was provided. Despite this evidence, a significant gap has since been identified related to how the American Psychiatric Association (APA) decides to accept proposed revisions to diagnostic criteria. The goal of the current special issue is to address this gap. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Personality pathology in youth: A comparison of the categorical and alternative model in relation to internalizing and externalizing pathology and age-adequate psychosocial functioning.

Youth with personality pathology are at a greater risk of developing broader psychopathology and experiencing poorer life outcomes in general. Therefore, detecting personality problems, specifically features of borderline personality disorder (BPD), provides opportunities for early intervention. In this study, we investigated the incremental value of Criteria A and B of the alternative model for personality disorders (AMPD) compared to a BPD symptom count based on the Diagnostic and Statistical Manual of Mental Disorders, fifth edition Section II personality disorder model in broader psychopathology (i.e., internalizing and externalizing symptoms) and age-adequate psychosocial functioning (i.e., attainment of developmental milestones). In a clinical sample of 246 young people (Mage = 19.22, SD = 2.76, 81.7% female), separate path analyses showed that a BPD symptom count, Criterion A, and Criterion B were all relatively strongly related to the outcome measures. In a combined path model, the AMPD and especially Criterion B explained additional variance in internalizing and externalizing pathology and age-adequate psychosocial functioning. The current results underscore the value of the AMPD for the early detection of negative psychopathological and psychosocial outcomes commonly associated with BPD.

Exploring personality correlates of psychiatric hospitalization: A cross-sectional comparison of section ii personality disorder model and alternative model for personality disorders.

Our cross-sectional study provides a head-to-head comparison of Section II and Section III of Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnostic models of personality disorders (PDs) in identifying significant personality correlates of psychiatric hospitalization (PH). PH is an indicator of a breakdown in one's existing ability to manage mental crisis. The sample was recruited from psychiatric clinical services (N = 60) as well as universities and the local community (N = 49). We used the Structured Clinical Interview for DSM-5 PD (SCID-5-PD) for Section II DSM-5 diagnosis, the Self and Interpersonal Functioning Scale (SIFS) for Criterion A and the Personality Inventory for DSM-5 (PID-5) for Criterion B. Separate logistic regressions analyses showed high discriminative utility for all diagnostic models: the number of Section II diagnosis, level of personality functioning, and five maladaptive traits (AUC between .89 and .97). Binomial logistic regression with a forward stepwise procedure showed that Section II number of diagnoses revealed incremental utility over Criteria A and B in distinguishing between individuals experiencing a mental health crisis requiring PH and those not requiring immediate intervention. We conclude that each diagnostic model, when considered individually, exhibits a high degree of discriminatory performance. However, employing all these models concurrently for identifying personality correlates of PH proves impractical. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Early Change as a Predictor of Treatment Outcome in Patients with a Personality Disorder.

A significant proportion of patients with a personality disorder do not benefit from treatment. Monitoring treatment progress can help adjust ineffective treatments. This study examined whether early changes in symptoms and personality dysfunction during the first phase of therapy could predict treatment outcomes. Data from 841 patients who received specialized treatment for personality disorders were analyzed. The study focused on whether changes in the Outcome Questionnaire-45.2 (OQ-45.2) symptom distress scale (SD), the General Assessment of Personality Disorder (GAPD), and Severity Indices of Personality Problems (SIPP) in the early phase of therapy predicted post-treatment personality dysfunction, as measured by the SIPP and GAPD. Early changes within a specific SIPP domain were the strongest predictors of post-treatment outcomes in that same domain. Early changes in symptoms significantly predicted outcomes in Self-Control, Relational Functioning, and Identity Integration, while the GAPD predicted outcomes in Self-Control and Social Attunement on the SIPP. For the GAPD, early changes on the GAPD itself, followed by early changes on the OQ-45 SD and the SIPP domain Social Attunement, were significant predictors. Thus, when it comes to personality dysfunction, early changes in a specific domain or measure are the best predictors of outcomes in that same domain. While the OQ-45 predicted some aspects of personality dysfunction, it should not replace disorder-specific measures. Additionally, the SIPP domains and the GAPD should not be used interchangeably to predict each other. In sum, considering these factors, monitoring early change can be useful in assessing progress in the treatment of patients with personality disorders.

Pathological personality domains and punishment-enhanced error-related negativity.

The error-related negativity (ERN) is an event-related potential that is observed after the commission of an error and is hypothesized to index threat sensitivity. The ERN is associated with multiple psychiatric disorders, but it is unclear if similar results are due to higher-order dimensions of psychopathology. When errors are punished, the ERN is further enhanced, which might better isolate threat sensitivity. However, few studies have examined whether psychopathology is associated with punishment enhancement of the ERN. In a clinical sample of 170 adults, the present study examined the association between pathological personality domains and predictable vs. unpredictable punishment-enhanced ERN. Results indicated that the ERN was enhanced when errors were punished compared to not punished. Greater negative emotionality was associated with a greater predictable punishment-enhanced ERN, while greater disinhibition was associated with smaller predictable punishment-enhanced ERN. The study suggests that higher-order pathological personality domains demonstrate discriminate relationships with punishment-enhanced error-related brain activity.

Exploring the Associations of Personality and Sexual Health Using the DSM-5 Alternative Model for Personality Disorders.

This study explored the relationships between sexual health indicators (i.e., sexual satisfaction, distress, and function) and the DSM-5 Alternative Model for Personality Disorders, a promising dimensional framework for assessing personality pathology. A sample of 489 participants seeking help in private practice clinics completed self-report measures of sexual satisfaction, distress, and function, as well as dyadic adjustment, psychological distress, romantic attachment, personality impairment, and pathological personality facets. Results first showed that participants reaching the cutoffs for a personality disorder had significantly higher sexual distress and lower sexual function compared to participants without a personality disorder. Second, path analyses controlling for psychological distress, dyadic adjustment, and romantic attachment revealed that, for women, the Criterion B Intimacy Avoidance facet was consistently linked with higher sexual distress and lower sexual satisfaction and function. For men, result patterns were more complex, linking Criterion B Separation Insecurity with high sexual distress, and Separation Insecurity and Intimacy Avoidance facets with low sexual function. In addition, Criterion B Irresponsibility, Rigid Perfectionism, as well as Criterion A Intimacy impairment were linked with higher sexual satisfaction. These findings improve our understanding of the links between personality and sexual health and provide support for considering personality difficulties in sexual health interventions.

General and distinct correspondence between personality disorder and interpersonal functioning.

The alternative model of personality disorders (AMPD) in DSM-5 includes interpersonal dysfunction as a core construct as a global severity dimension. However, it is less known how various interpersonal characteristics contribute to both general and distinct dimensions of personality dysfunction. In participants from community sources, we obtained responses to Levels of Personality Functioning Scale-Self Report (LPFS-SR), maladaptive traits (PID-5-BF), and social relationship patterns, including those related to close relationships and quantitative measures of network size. Canonical correlation analysis mapped conjoint associations between two sets of variables (personality scales and social relationship) and identified three distinct modes of correlation as significant. The first canonical pattern represented global dysfunction and was associated with utilitarianism, short-termed, weaker strengths, and smaller network sizes. The second canonical correlation represented externalizing traits and was associated with a larger number of relationships, higher utilitarianism, and short-term relationships with a close significant other. The third canonical correlation represented a detached, unemotional, and callous personality which corresponded with weaker relationship strength with both the mother and a close significant other. Our findings suggest that interpersonal functioning corresponding to personality dysfunction can be distinguished into both common and specific characteristics and further highlight the importance of characterizing distinct patterns within close relationships.

Self-Reported ICD-11 Personality Disorder Severity in Peruvian Adolescents: Structure, Validity, and Tentative Cutoffs.

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

Examining the Validity of the Levels of Personality Functioning Questionnaire for Adolescents Aged 12-18 (LOPF-Q 12-18): A Replication and Extension With a Sample of Lithuanian Adolescents.

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

Mapping Emotion Regulation Patterns Within the Alternative Model of Personality Disorders Personality Traits.

Personality pathology is associated with emotional problems that are potentially attributable to problematic emotion regulation strategy patterns. We evaluated the emotion regulation strategies associated with the pathological personality traits in the Alternative Model of Personality Disorders (AMPD). A total of 504 participants completed measures of AMPD traits and strategy usage, which were analyzed using hierarchical regressions and latent profile analysis (LPA). Regression results demonstrated that each trait was associated with a unique strategy pattern: negative affect with emotional overengagement, detachment with socialemotional avoidance, antagonism with emotional externalization/avoidance, disinhibition with emotional avoidance and overengagement, and psychoticism with strategies linked to psychotic/dissociative experiences. The LPA identified three profiles with heightened AMPD traits: an internalizing/distressed profile, an externalizing/distressed profile, and a schizoid-schizotypal profile; each had a unique strategy pattern that varied depending on trait composition. This research highlights the relevance of emotion regulation strategy patterns in the assessment, conceptualization, and treatment of personality pathology.

Exploring the Nexus: Personality Disorders and Their Impact on Violent Extremism, Radicalism, and Activism.

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

Trauma-focused and personality disorder treatment for posttraumatic stress disorder and comorbid cluster C personality disorder: a randomized clinical trial.

Background: Posttraumatic stress disorder (PTSD) is associated with high rates of cluster C personality disorders (PD), which may negatively affect PTSD treatment. It is unknown whether concurrent treatment for PTSD and comorbid PD leads to superior treatment effects, compared to standard trauma-focused treatment.Objective: The objective was to test the efficacy of adding personality disorder treatment (group schema therapy; GST) to individual trauma-focused treatment (imagery rescripting; ImRs).Method: A two-arm randomized clinical trial (1:1 allocation ratio) was conducted between 2018 and 2023 at two sites of a mental health institution in the Netherlands. Raters were blind to treatment allocation. Adult outpatients with PTSD and comorbid cluster C personality disorders were randomized to receive either ImRs (12-18 sessions) or ImRs + GST (12-18 ImRs + 52-58 GST). The main outcome was PTSD severity one year after start of treatment measured with the Clinician-Administered PTSD Scale for DSM-5.Results: Of 130 patients (mean [SD] age = 40.6 [11.2], 110 [85%] females), 66 were assigned to ImRs and 64 to ImRs + GST. At 12 months, there were large decreases in PTSD severity (dImRs = 2.42, 95%CI = 1.97-2.87; dImRs + GST = 2.44, 95%CI = 1.99-2.90), but there was no significant difference between conditions (d = 0.02, 95%CI = -0.33-0.36, p = .944). Reductions in personality disorder symptoms and all other secondary outcomes were observed in both conditions. There were no significant differences between conditions on any of the secondary outcomes at 12 months.Conclusion: The more intensive concurrent trauma-focused and personality disorder treatment (ImRs + GST) was not superior to trauma-focused treatment alone (ImRs) for patients with PTSD and comorbid CPD. This suggests that trauma-focused treatment is the preferred primary treatment in patients presenting with both internalizing personality disorder and PTSD, reserving the stepping up to more intensive psychotherapy aimed at the personality disorder as a second line of treatment.Trial registration: ClinicalTrials.gov identifier: NCT03833531.

Concurrent trauma-focused and personality disorder treatment was not superior to only trauma-focused treatment for patients with posttraumatic stress disorder (PTSD) and comorbid cluster C personality disorders.Large reductions in PTSD severity and medium-to-large reductions in all secondary outcomes, including personality disorder symptoms, were observed in both treatment arms.These findings are remarkable, given the higher therapy dosage and specialized treatment for personality disorder comorbidity in the combined treatment arm.
