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.

The 24-Year Course of Symptomatic Disorders in Patients With Borderline Personality Disorder and Personality-Disordered Comparison Subjects: Description and Prediction of Recovery From BPD.

Objectives: Our first objective was to compare the prevalence of symptomatic disorders (formerly Axis I disorders) over 24 years of prospective follow-up among patients with borderline personality disorder (BPD) and other personality disordered comparison subjects as well as recovered vs nonrecovered borderline patients. Our second objective was to assess the relationship between the absence of 5 major classes of symptomatic disorders over time and the likelihood of concurrent recovery among borderline patients.Methods: The McLean Study of Adult Development (MSAD) is a naturalistic prospective follow-up study of 362 inpatients assessed at 12 contiguous 2-year follow-up waves. Symptomatic disorders were assessed at each follow-up using the Structured Clinical Interview for DSM-III-R Axis I Disorders. Generalized estimating equations were used to assess all outcomes. Data were collected from June 1992 to December 2018.Results: Patients with BPD had significantly higher rates of all 5 types of disorders studied than comparison subjects. However, the prevalence of these disorders declined significantly over time at similar rates for both study groups. This finding was similar for recovered and nonrecovered borderline patients. When the absence of these types of comorbid disorders was used to predict recovery status, substance use disorders were a substantially stronger predictor of recovery than the other 4 classes of disorders (relative risk ratio: 2.53, P < .001).Conclusions: The results of this study suggest that symptomatic disorders co occur less commonly with BPD over time, particularly for recovered borderline patients. They also suggest that the absence of substance use disorders is the strongest predictor of achieving recovery from BPD.

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.

Mental Health Hospitalizations in Canadian Children, Adolescents, and Young Adults Over the COVID-19 Pandemic.

Importance: The COVID-19 pandemic resulted in multiple socially restrictive public health measures and reported negative mental health impacts in youths. Few studies have evaluated incidence rates by sex, region, and social determinants across an entire population. Objective: To estimate the incidence of hospitalizations for mental health conditions, stratified by sex, region, and social determinants, in children and adolescents (hereinafter referred to as youths) and young adults comparing the prepandemic and pandemic-prevalent periods. Design, Setting, and Participants: This Canadian population-based repeated ecological cross-sectional study used health administrative data, extending from April 1, 2016, to March 31, 2023. All youths and young adults from 6 to 20 years of age in each of the Canadian provinces and territories were included. Data were provided by the Canadian Institute for Health Information for all provinces except Quebec; the Institut National d'Excellence en Santé et en Services Sociaux provided aggregate data for Quebec. Exposures: The COVID-19-prevalent period, defined as April 1, 2020, to March 31, 2023. Main Outcomes and Measures: The main outcome measures were the prepandemic and COVID-19-prevalent incidence rates of hospitalizations for anxiety, mood disorders, eating disorders, schizophrenia or psychosis, personality disorders, substance-related disorders, and self-harm. Secondary measures included hospitalization differences by sex, age group, and deprivation as well as emergency department visits for the same mental health conditions. Results: Among Canadian youths and young adults during the study period, there were 218 101 hospitalizations for mental health conditions (ages 6 to 11 years: 5.8%, 12 to 17 years: 66.9%, and 18 to 20 years: 27.3%; 66.0% female). The rate of mental health hospitalizations decreased from 51.6 to 47.9 per 10 000 person-years between the prepandemic and COVID-19-prevalent years. However, the pandemic was associated with a rise in hospitalizations for anxiety (incidence rate ratio [IRR], 1.11; 95% CI, 1.08-1.14), personality disorders (IRR, 1.21; 95% CI, 1.16-1.25), suicide and self-harm (IRR, 1.10; 95% CI, 1.07-1.13), and eating disorders (IRR, 1.66; 95% CI, 1.60-1.73) in females and for eating disorders (IRR, 1.47; 95% CI, 1.31-1.67) in males. In both sexes, there was a decrease in hospitalizations for mood disorders (IRR, 0.84; 95% CI, 0.83-0.86), substance-related disorders (IRR, 0.83; 95% CI, 0.81-0.86), and other mental health disorders (IRR, 0.78; 95% CI, 0.76-0.79). Conclusions and Relevance: This cross-sectional study of Canadian youths and young adults found a rise in anxiety, personality disorders, and suicidality in females and a rise in eating disorders in both sexes in the COVID-19-prevalent period. These results suggest that in future pandemics, policymakers should support youths and young adults who are particularly vulnerable to deterioration in mental health conditions during public health restrictions, including eating disorders, anxiety, and suicidality.

Can Patients With Narcissistic Personality Disorder Change? A Case Series.

ABSTRACT: The study was set out to establish the potential for psychotherapy to effect improvements in patients with narcissistic personality disorder (NPD). Eight patients with NPD who improved in treatment were identified. Consensus clinician/investigator diagnostic scores from before and after the psychotherapies were retroactively established on the Diagnostic Interview for Narcissism (DIN) and the Diagnostic Statistic Manual for Psychiatric Disorders, 5th Edition (DSM-5) Personality Disorder Section II criteria. Psychosocial functioning (work or school, romantic relationships) before and after the psychotherapies was retroactively evaluated as well. At the completion of the therapies after 2.5 to 5 years, all patients had improved, no longer met DIN or DSM-5 criteria for NPD, and showed better psychosocial functioning. Symptomatic improvements were associated with large effect sizes. In conclusion, changes in NPD can occur in treatment after 2.5 to 5 years. Future research should identify patient characteristics, interventions, and common processes in such improved cases that could help with development of treatments.

Psychoeducation for Pathologic Narcissism and Narcissistic Personality Disorder: A Review and Proposal for a Good Psychiatric Management-based Six-week Group Program.

Pathologic narcissism (PN) and narcissistic personality disorder (NPD) are 2 common and stigmatized clinical constructs that are known to have large consequences for patients' functioning and mental health-related outcomes. To date, no treatment for these conditions has been empirically validated, but there is a relative consensus about the importance of psychoeducation. Here we present a model for a psychoeducational intervention for patients with PN or NPD. We start with a review of the current evidence on the role of psychoeducation in different treatment models for PN, and we discuss several aspects regarding the content and format of this type of intervention. Based on this review, we outline a 6-week Good Psychiatric Management-based psychoeducation group program that we developed. We also describe how such a psychoeducational intervention can be implemented individually, with fewer resources, in general care settings. Finally, we discuss the strengths and limitations of our approach and elaborate on the rationale for our proposal. We believe that this program proposal is a first step in the development of psychoeducational programs for PN and NPD that can be further corrected and enhanced.

Predictors of treatment attendance in patients with posttraumatic stress disorder and comorbid personality disorders.

INTRODUCTION: High dropout and low treatment attendance rates among patients with posttraumatic stress disorder (PTSD) and personality disorders (PDs) continue to pose a significant challenge. Despite numerous studies focusing on enhancing treatment attendance, the identification of consistent and reliable predictors in patients with PTSD and comorbid PDs remains limited. OBJECTIVES: This study aims to investigate a wide range of potential predictors of treatment attendance, encompassing demographic, patient-severity, treatment, and therapist-related variables in patients with PTSD and comorbid borderline and/or cluster C PDs. METHODS: Utilizing data from 255 patients participating in two randomized controlled trials comparing trauma-focused treatment with or without concurrent PD treatment, candidate predictors were individually analyzed in univariate regression models. Significant predictors were then combined in a multiple ordinal regression model. RESULTS: In total, 40% of patients attended fewer trauma-focused treatment sessions than the minimum recommended in treatment guidelines. Out of the 38 candidate predictors examined, five significant, independent predictors of treatment attendance emerged in a multiple ordinal regression model. Higher baseline PTSD severity (OR = 1.04, p = .036), higher education level (OR = 1.22, p = .009) and a stronger patient-rated working alliance (OR = 1.72, p = .047) with the therapist predicted higher treatment attendance. Conversely, inadequate social support from friends (OR = 0.90, p = .042) and concurrent PD treatment and trauma-focused treatment (OR = 0.52, p = .022) were associated with lower treatment attendance. CONCLUSIONS: In conclusion, this constitutes the first study investigating predictors of treatment attendance in patients with PTSD and comorbid PDs. The results highlight the complexity of pinpointing reliable predictors. Nevertheless, the identification of five predictors provides valuable insights, aiding clinicians in customizing treatment strategies for individual patients and enhancing overall treatment attendance.

Collaborative assessment as an intervention in the treatment of mental Illness: a systematic review.

BACKGROUND: Three meta-analyses suggested that the psychological assessment as a therapeutic intervention approach might have therapeutic effects but had unspecific inclusion criteria. METHODS: We searched four databases for RCTs that reported on the use of psychological assessment as an intervention. Two reviewers independently selected papers, extracted data, and assessed study quality.We conducted and reported the systematic review following the PRISMA statement. We assessed the Risk of bias in included studies using the Risk of Bias tool and graded the strength of the evidence with GRADE. RESULTS: We included two RCTs: The first study investigated Therapeutic Assessment (TA) combined with Manual-Assisted Cognitive Behavior Therapy (MACT) compared with MACT only in 16 outpatients with personality disorders. The trial found among completers (n = 7) no difference in borderline symptomatology but a possible difference regarding suicidality favoring MACT + TA. The trial did not provide any outcomes relating to readiness for treatment. The other trial investigated TA compared with a Goal-focused Pretreatment Intervention in a sample of 74 outpatients with personality disorders. The results found no intervention effects on symptomatology but suggested that TA might improve patient expectancy for future treatment among completers of the intervention. Both trials were judged at a high risk of bias and with very low certainty of evidence. DISCUSSION: We found no support for the clinical effect of psychological assessment as a therapeutic intervention due to the high risk of bias and low certainty of the evidence.

Mentalization based treatment for a broad range of personality disorders: a naturalistic study.

BACKGROUND: Several studies have observed that mentalization-based treatment (MBT) is an effective treatment for borderline personality disorder (BPD), but its effectiveness for other personality disorders (PDs) has hardly been examined. Additionally, the evidence supporting the claim that MBT improves mentalizing capacity is scarce. The present study examined whether (i) patients with a broad range of PDs enrolled in an MBT program would improve on several outcome measures (ii) mentalizing capacity would improve over time; (iii) patients with BPD would improve more than those with non-borderline PDs. METHOD: Personality disorders, psychiatric symptoms, social functioning, maladaptive personality functioning and mentalizing capacity were measured in a group of individuals with various PDs (n = 46) that received MBT. Assessments were made at baseline and after 6, 12, and 18 months of treatment. The severity of psychiatric symptoms, measured using the Outcome Questionnaire 45, was the primary outcome variable. RESULTS: Overall, enrollment in the MBT program was associated with a decrease in psychiatric symptoms and an improvement of personality functioning, social functioning for a mixed group of PDs (all p's ≤ .01). Bigger effect sizes were observed for BPD patients (n = 25) than for patients with non-BPD (n = 21), but the difference failed to reach statistical significance (p = 0.06). A primary analysis showed that the decrease in psychiatric symptoms was significant in BPD patients (p = 0.01), not in non-BPD (p = 0.19) patients. However, a sufficiently powered secondary analysis with imputed data showed that non-BPD patients reported a significant decrease in psychiatric symptoms too (p = 0.01). Mentalizing capacity of the whole group improved over time (d = .68 on the Toronto Alexithymia Scale and 1.46 on the Social Cognition and Object Relations System). DISCUSSION: These results suggest that MBT coincides with symptomatic and functional improvement across a broad range of PDs and shows that MBT is associated with improvements in mentalizing capacity. As the study is not experimental in design, we cannot make causal claims. CONCLUSION: Mentalization-based treatment may be an effective treatment for patients with a broad range of PDs. TRIAL REGISTRATION: The study design was approved by the Leiden University Ethical Committee.

Clinical effectiveness and cost-effectiveness of Structured Psychological Support for people with probable personality disorder in mental health services in England: study protocol for a randomised controlled trial.

INTRODUCTION: Evidence-based psychological treatments for people with personality disorder usually involve attending group-based sessions over many months. Low-intensity psychological interventions of less than 6 months duration have been developed, but their clinical effectiveness and cost-effectiveness are unclear. METHODS AND ANALYSIS: This is a multicentre, randomised, parallel-group, researcher-masked, superiority trial. Study participants will be aged 18 and over, have probable personality disorder and be treated by mental health staff in seven centres in England. We will exclude people who are: unwilling or unable to provide written informed consent, have a coexisting organic or psychotic mental disorder, or are already receiving psychological treatment for personality disorder or on a waiting list for such treatment. In the intervention group, participants will be offered up to 10 individual sessions of Structured Psychological Support. In the control group, participants will be offered treatment as usual plus a single session of personalised crisis planning. The primary outcome is social functioning measured over 12 months using total score on the Work and Social Adjustment Scale (WSAS). Secondary outcomes include mental health, suicidal behaviour, health-related quality of life, patient-rated global improvement and satisfaction, and resource use and costs. The primary analysis will compare WSAS scores across the 12-month period using a general linear mixed model adjusting for baseline scores, allocation group and study centre on an intention-to-treat basis. In a parallel process evaluation, we will analyse qualitative data from interviews with study participants, clinical staff and researchers to examine mechanisms of impact and contextual factors. ETHICS AND DISSEMINATION: The study complies with the Helsinki Declaration II and is approved by the London-Bromley Research Ethics Committee (IRAS ID 315951). Study findings will be published in an open access peer-reviewed journal; and disseminated at national and international conferences. TRIAL REGISTRATION NUMBER: ISRCTN13918289.

The Portuguese version of the self-report form of the DSM-5 Level of Personality Functioning Scale (LPFS-SR) in a community and clinical sample.

The Level of Personality Functioning Scale-Self-Report (LPFS-SR) operationalizes Criterion A of the DSM-5 Alternative Model for Personality Disorders. The current study aimed 1) to examine the internal consistency of the Portuguese version of the LPFS-SR in a community sample and a clinical sample, 2) to compare non-clinical participants (N = 282, Mage = 48.01, SD = 10.87) with two samples of clinical participants, one composed of patients with a personality disorder diagnosis (PD sample, n = 40, Mage = 46.18, SD = 13.59) and the other of patients with other psychiatric diagnoses (OD sample, n = 148, Mage = 49.49, SD = 11.88), with respect to LPFS-SR dimensions and total score, 3) to examine the capacity of the LPFS-SR to discriminate between samples through the ROC curve analyses, and 4) to examine the factor structure of the Portuguese version of the LPFS-SR. The Portuguese version of the LPFS-SR revealed adequate internal consistency results, akin to the original data, in the community and clinical samples. The community sample differed significantly from both clinical samples in all the LPFS-SR dimensions and total score. The ROC curve analysis indicated an optimal cut-off for the total score of 272.00, corresponding to a sensitivity of 75% and a specificity of 89%, in the PD vs. community samples. The LPFS-SR total score discriminative capacity between the PD and OD samples was lower, albeit also significant (area-under-the-curve of .63; p = .027; 95% CI: .52-.74). The current study provided evidence of the LPFS-SR's unidimensionality in both community and clinical samples. Although this study has limitations, its findings contribute to a deeper understanding of the LPFS-SR construct, as well as to its cross-cultural validation.

Repeated intentional foreign body ingestion, what can be done?

Repeated intentional foreign body ingestion (RIFBI) in patients with Emotionally Unstable Personality Disorder (EUPD) is a common clinical presentation to the emergency department. The relationship between repeated foreign body ingestion and a co-existent personality disorder diagnosis is complex, making it challenging to manage. Our institution implemented a novel interdisciplinary model of care for RIFBI as a way of improving health outcomes in this cohort of patients. Our observations following the model of care are presented herein. We encourage other health networks to adopt this model of care for managing RIBFI in EUPD.

Does personality dysfunction add incremental utility over general psychopathology when modeling previous suicide attempts in adolescent patients?

BACKGROUND: Identifying patients at risk for a suicide attempt (SA) is critical in adolescents with mental disorders. The current study aimed to 1) examine whether personality dysfunction (PD) is associated with previous SA, 2) explore the incremental utility of PD over psychiatric disorders in modeling previous SA. METHODS: The sample comprised of n = 498 adolescent patients (mean age = 15.41 years, 79.12 % females, inpatient 48.8 %, outpatient 51.2 %). SA in the past year, PD according to the alternative DSM-5 model for personality disorders, and psychiatric diagnoses were assessed using semi-structured interviews. Logistic regression and principal component analysis examining the associations and specific patterns of PD and SA in the past year were conducted. Hierarchical (stepwise) logistic regression was applied to investigate the incremental utility of PD over that of psychiatric diagnoses to identify individuals with SA in the past year. RESULTS: Including all facets of PD revealed a significant model with SA in the past year as outcome (χ2(12) = 106.65, McFaddens Pseudo-R2 = 0.17, p < 0.01). Adding PD to the model explained a significant amount of variance in past SA over that of psychiatric diagnoses (Pseudo-R2 = 0.18, Wald χ2 = 43.05, p < 0.01). LIMITATIONS: As we only studied past SA and due to the cross-sectional design, no conclusion regarding the prediction of future SA can be drawn. DISCUSSION: PD should routinely be assessed in adolescent patients since individuals with PD are more likely to have attempted suicide even when controlling for comorbid psychiatric disorders. PD may represent an important target for intervention in those with suicidal thoughts and behaviors.

An Evolutionary Perspective on the DSM-5 Alternative Model for Personality Disorders.

Recent work has nested the Alternative Model for Personality Disorders (AMPD) within several theoretical paradigms of personality and clinical psychology (e.g., multivariate, psychodynamic). This has both spurred on additional research and aided in practical application. Connecting the model to other theoretical heuristics may lead to further advances. One candidate for such a theory is that of evolutionary psychology, which attempts to provide explanations of human behavior (including personality traits) rooted in adaptation. In this article, we review and integrate the theoretical and empirical literature on the AMPD and evolutionary psychology, providing a synthesis of the two models in the hope of furthering the research and application of both.

Understanding the Interplay Between ICD-11 Complex PTSD and Personality Disorder Features in Relation to Traumatic Life Events in a Trauma-Exposed Community Sample.

In the ICD-11, PD and CPTSD overlap in impaired aspects of self- and interpersonal functioning, with implications for assessment and treatment. This article aimed to explore the relationship between CPTSD and PD features. A trauma-exposed community sample in Denmark (N = 470) completed the ITQ, PDS-ICD-11, and BTQ. Data were analyzed using exploratory structural equation modeling. Both two- and three-factor models were viable. In the two-factor model, both disturbances in self-organization (DSO) and PD items belonged to the same disturbed self-interpersonal functioning factor. Both factors predicted quality of life and functioning and were predicted by number of life events. In the three-factor model (PTSD, DSO, and PD), there was some overlap between DSO and PD items. Number of life events predicted belonging to the PTSD and DSO classes but not the PD class. The findings demonstrate clear overlapping and differentiating features. Multiple traumas and functioning in self-concept and relationships appear to differentiate.

Psychiatrists' Perspectives on Prescription Decisions for Patients With Personality Disorders.

There is currently insufficient evidence for the use of a specific pharmacological treatment for personality disorders (PD). The research literature lacks a systematic exploration of clinicians' experiences of pharmacological treatment of PD. The aim of the qualitative study was to examine how psychiatrists make decisions about pharmacological treatment for patients with PD. The interviews were analyzed using inductive thematic analysis. The results showed that ambiguous guidelines had the effect that the psychiatrists often relied on their own experience, or that of their colleagues. As a basis for decisions concerning drug treatment, an interpersonal component was also identified. Some of the psychiatrists in the current study argued that medications may be part of the alliance-building with the patient and that medications were a way of tying the patient to the clinic. Our findings show that it is important to work on how the clinical guidelines should be implemented in practice.
