Trauma exposure and diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) posttraumatic stress disorder among Danish adults: Implications of narrow and broad operationalizations of criterion A.

OBJECTIVE: Posttraumatic stress disorder (PTSD) has long been recognized as a debilitating psychiatric disorder. The definition of Criterion A has been a topic of controversy, and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and International Classification of Diseases, 11th version have opted for a narrow and a broad approach to the gatekeeper criterion, respectively. The aim of this study was to test the implications of a narrow (DSM-5) versus broad (including psychologically threatening events) Criterion A for endorsement of a probable PTSD diagnosis and symptom severity. METHOD: The study was based on a cross-sectional survey conducted in March 2021 among the general population of adult Danish residents in Denmark, ranging in age between 18 and 79 years (n = 1,033). RESULTS: Psychologically threatening events did not lead to a statistically significant increase in probable PTSD diagnoses, but psychologically threatening events were independently related to probable PTSD risk and severity. Controlling for other potentially traumatizing events and demographic factors, psychologically threatening events were the strongest risk factor for higher symptom severity. We found probable PTSD rates higher but comparable to other Scandinavian countries such as Norway and Sweden. CONCLUSION: Exposure to psychologically threatening events is an important factor in explaining probable PTSD risk and severity although not independently leading to a significant increase in probable PTSD rates. Probable rates of DSM-5 PTSD are higher than Danish official estimates in a random sample of the Danish adult population (6.8%-6.9% compared to 1%). The generalizability of study findings is limited by nonrepresentativity, the use of self-report measures, and assessment during the COVID-19 lockdown.

Short-Term versus Long-Term Mentalization-Based Therapy for Borderline Personality Disorder: A Randomized Clinical Trial (MBT-RCT).

INTRODUCTION: Borderline personality disorder (BPD) is a severe and prevalent psychiatric disorder. Mentalization-based therapy (MBT) is an evidence-based intervention for BPD, and several countries offer treatment programs for BPD lasting for years, which is resource demanding. No previous trial has compared short-term with long-term MBT. OBJECTIVE: The aim of the study was to assess the efficacy and safety of short-term versus long-term MBT for outpatients with BPD. METHODS: Adult outpatients (≥18 years) with subthreshold or diagnosed BPD were randomly assigned (1:1) to short-term MBT (5 months) or long-term MBT (14 months). The primary outcome was BPD symptoms assessed with the Zanarini Rating Scale for Borderline Personality Disorder. Secondary outcomes were functional impairment, quality of life, global functioning, and severe self-harm. All outcomes were primarily assessed at 16 months after randomization. This trial was prospectively registered at ClinicalTrials.gov, NCT03677037. RESULTS: Between October 4, 2018, and December 3, 2020, we randomly assigned 166 participants to short-term MBT (n = 84) or long-term MBT (n = 82). Regression analyses showed no evidence of a difference when assessing BPD symptoms (MD 0.99; 95% CI: -1.06 to 3.03; p = 0.341), level of functioning (MD 1.44; 95% CI: -1.43 to 4.32; p = 0.321), quality of life (MD -0.91; 95% CI: -4.62 to 2.79; p = 0.626), global functioning (MD -2.25; 95% CI: -6.70 to 2.20; p = 0.318), or severe self-harm (RR 1.37; 95% CI: 0.70-2.84; p = 0.335). More participants in the long-term MBT group had a serious adverse event compared with short-term MBT (RR 1.63; 95% CI: 0.94-3.07; p = 0.088), primarily driven by a difference in psychiatric hospitalizations (RR 2.03; 95% CI: 0.99-5.09; p = 0.056). CONCLUSION: Long-term MBT did not lead to lower levels of BPD symptoms, nor did it influence any of the secondary outcomes compared with short-term MBT.

ICD-11 personality disorder features in the danish general population: Cut-offs and prevalence rates for severity levels.

INTRODUCTION: Prevalence rates and correlates of personality disorders (PD) are relevant to health care policy and planning. OBJECTIVES: To present normative data for self-reported ICD-11 personality disorder (PD) features including tentative cut-off scores and prevalence rates for severity levels along with psychosocial correlates. METHODS: The Personality Disorder Severity ICD-11 (PDS-ICD-11) scale and criterion measures of impairment were administered to a social-demographically stratified sample of Danish citizens (N = 8,941) of which 3,044 delivered complete data. Item-Response Theory (IRT) was employed to indicate cut-offs based on standard deviations from the latent mean. RESULTS: The unidimensionality of the PDS-ICD-11 score was supported and IRT analysis suggested norm-based thresholds at latent severity levels. Expected associations with criterion measures were found. CONCLUSION: The normative data portray ICD-11 PD features in the general population and allow for interpretation of PDS-ICD-11 scores (e.g., scores of 12, 16, and 19 may indicate mild, moderate, and severe dysfunction), which may inform health care policy and planning. A total weighted prevalence of 6.9 % of the Danish general population is estimated to have clinically significant personality dysfunction, proportionally composed of Mild (4.8 %), Moderate (1.2 %), and Severe (0.9 %) levels. Future research should corroborate these findings using relevant clinical samples and methods.

The difference between shorter- versus longer-term psychotherapy for adult mental health disorders: a systematic review with meta-analysis.

BACKGROUND: The optimal psychotherapy duration for mental health disorders is unclear. Our aim was to assess the beneficial and harmful effects of shorter- versus longer-term psychotherapy for adult mental health disorders. METHOD: We searched relevant databases and websites for published and unpublished randomised clinical trials assessing different durations of the same psychotherapy type before June 27, 2022. Our methodology was based on Cochrane and an eight-step procedure. Primary outcomes were quality of life, serious adverse events, and symptom severity. Secondary outcomes were suicide or suicide-attempts, self-harm, and level of functioning. RESULTS: We included 19 trials randomising 3,447 participants. All trials were at high risk of bias. Three single trials met the required information size needed to confirm or reject realistic intervention effects. One single trial showed no evidence of a difference between 6 versus 12 months dialectical behavioral therapy for borderline personality when assessing quality of life, symptom severity, and level of functioning. One single trial showed evidence of a beneficial effect of adding booster sessions to 8 and 12 weeks of internet-based cognitive behavioral therapy for depression and anxiety when assessing symptom severity and level of functioning. One single trial showed no evidence of a difference between 20 weeks versus 3 years of psychodynamic psychotherapy for mood- or anxiety disorders when assessing symptom severity and level of functioning. It was only possible to conduct two pre-planned meta-analyses. Meta-analysis showed no evidence of a difference between shorter- and longer-term cognitive behavioural therapy for anxiety disorders on anxiety symptoms at end of treatment (SMD: 0.08; 95% CI: -0.47 to 0.63; p = 0.77; I2 = 73%; four trials; very low certainty). Meta-analysis showed no evidence of a difference between shorter and longer-term psychodynamic psychotherapy for mood- and anxiety disorders on level of functioning (SMD 0.16; 95% CI -0.08 to 0.40; p = 0.20; I2 = 21%; two trials; very low certainty). CONCLUSIONS: The evidence for shorter versus longer-term psychotherapy for adult mental health disorders is currently unclear. We only identified 19 randomised clinical trials. More trials at low risk of bias and at low risk of random errors assessing participants at different levels of psychopathological severity are urgently needed.

National norms of mental health for Denmark.

INTRODUCTION: To facilitate interpretation and clinical utility of patient-reported outcomes, normative data provide a reference for a person's score on a particular outcome in relation to the general population. This study reports Danish general population norms for four mental health indicators, assessing social functioning (Sheehan Disability Scale, SDS) personal recovery (Brief INSPIRE-O), symptom burden (Symptom Check List-10, SCL-10) and subjective well-being (WHO-5). METHODS: The study was a cross-sectional survey study organized by the State's statistical authority among the general population of adult Danish residents in Denmark, ranging in age between 18 to 79 years. RESULTS: A total of 8003 citizens were contacted including reminders from 2 March 2019 to 11 April 2019 by electronic letters, resulting in 2819 (35%) citizens providing complete responses. Female gender, higher age, Danish origin and living with a partner were associated with increased participation, and decreased participation was observed in male immigrants. We found a mean score of subjective well-being slightly lower than the population norm typically found in Danish general population studies. Elderly persons, Danes, and persons living with a partner reported better subjective mental health. Subjective well-being and personal recovery were positively correlated with social contacts and self-reported general health rating, and negatively correlated with social functioning and symptoms of depression and anxiety. CONCLUSION: This normative data provides a reference for interpreting mental health status. Our findings indicate slightly poorer subjective mental health than previously found. There is a need for special attention to engaging male immigrants in studies on mental health in the general population.

Mentalizing the therapist - Therapist experiences with short-term mentalization-based therapy for borderline personality disorder: A qualitative study.

Background: Mentalization-Based Therapy (MBT) was originally developed as a structured psychotherapy approach developed to treat borderline personality disorder (BPD) lasting up to 18 months in outpatient settings. However, a short-term (5 months) MBT program has recently been developed. No studies have investigated how MBT therapists experience the shift towards conducting short-term MBT for BPD. Objective: The objective of this study was to explore therapist experiences with conducting short-term MBT for outpatients with BPD in the Danish mental health services. Methods: Semi-structured qualitative interviews were conducted with seven therapists about their experiences with short-term MBT after a one-year pilot phase. The interviews were verbatim transcribed and analyzed using thematic analysis. Results: The following four major themes from the therapists' experiences with short-term MBT were found in the qualitative analysis: (1) The longer the better, (2) Change processes can be intellectual or experiential, (3) Short-term therapy is hard work, and (4) Termination is more challenging in short-term MBT. Conclusion: Most therapists were overall reluctant towards changing from long-term to short-term MBT. These therapist experiences could inform implementation of short-term MBT in mental health settings in the future.

Mentalizing mediates the relationship between psychopathy and premeditated criminal offending in schizophrenia: a 6-year follow-up study.

PURPOSE: Research has shown that schizophrenia augments the risk for criminal behaviour and variables both defining- and related to schizophrenia, increase criminal offending. Premeditated criminal offending is considered a severe form of criminal offending, however, very little is known about what predicts future premeditated criminal offending in schizophrenia. METHOD AND MATERIALS: In this 6-year follow-up study we explored which factors underlie future premeditated criminal behaviour in a sample of patients diagnosed with schizophrenia (N = 116). We also investigated if a specific mentalizing profile underlie part of the variance of premeditated criminal offending. RESULTS: Results showed that psychopathy underlie future premeditated crime in schizophrenia, and that a specific mentalizing profile, comprised of a dysfunctional emotional and intact cognitive mentalizing profile in relation to others, mediated parts of the relation between psychopathy and premeditated criminal offending. Finally, our results indicated that patients with schizophrenia with a specific mentalizing profile (see above) engaged in premeditated criminal behaviour earlier during the 6-year follow-up period compared to patients with other mentalizing profiles. CONCLUSIONS: Our findings suggest that mentalization should carefully be inspected in patients with schizophrenia in relation to future premeditated offending.

Adapting Short-Term Mentalization-Based Therapy to ICD-11 Personality Disorder in Adolescents.

Following the introduction of the 11th revision of the International Classification of Diseases (ICD-11), adolescents can now be diagnosed with a personality disorder based on severity ranging from mild to moderate to severe. This dimensional model has potential implications for treatment, as it allows clinicians and researchers to search for effective treatments targeting adolescents at different severity levels rather than offering all patients the same treatment. In this conceptual paper, we propose that the short-term mentalization-based therapy (MBT) program, originally developed to treat adults with borderline personality disorder (BPD), has potential clinical advantages for adolescents with ICD-11 personality disorder at the mild to moderate severity level. The short-term MBT program is a 5-month structured treatment approach including individual therapy, combined psychotherapy with the individual therapist also being one of the group therapists, and closed-group therapy to enhance cohesion and a feeling of security. The purpose of this paper is to make a case for the use of this format, as opposed to the traditional long-term MBT format, for adolescents with BPD. Future research should include large-scale randomized clinical trials powered to assess patient-important outcomes.

Normative data for the LPFS-BF 2.0 derived from the Danish general population and relationship with psychosocial impairment.

The Level of Personality Functioning Scale-Brief Form 2.0 is a frequently used self-report inventory that may be used to screen for self- and interpersonal dysfunction according to the DSM-5 Alternative Model for Personality Disorders (AMPD) and the ICD-11 Classification of Personality Disorders. Nevertheless, reliable norms and cut-off scores to aid interpretation and clinical decision making are still lacking. The LPFS-BF and relevant impairment measures were administered to a sociodemographically stratisfied sample of 2,002 adults from the general Danish population of whom 713 individuals eventually delivered data for inclusion in the present study. The unidimensionality of the LPFS-BF scores was established using Confirmatory Factor Analysis (CFA). Item-Response Theory (IRT) analysis indicated satisfactory item functioning for all 12 items and suggested normative observed score thresholds at different latent severity levels. Meaningful associations were found between the LPFS-BF norm-based cut-off scores, quality of life, and social and occupational functioning. This study presented the first normative data for LPFS-BF, which specifically applies to Denmark but likely also other socioeconomically comparable Nordic and Western societies. These results allow for interpretation of LPFS-BF scores and clinical decision-making. Future research should corroborate these findings and compare them to scores obtained in other general population samples.

The in-session discourse of unresolved/disorganized psychotherapy patients: An exploratory study of an attachment classification.

The Unresolved/disorganized (U/d) attachment classification has generated considerable interest among clinicians. This is in part based on its empirical associations with adult mental health, parenting practices, and treatment outcomes. Despite decades of theorizing, however, we have little empirical information regarding how patients with a U/d classification assigned by accredited coders actually behave or speak in psychotherapy sessions. Here, we take a step towards bridging this gap by reporting our observations of the psychotherapy session transcripts of 40 outpatients who were independently classified as U/d on the Adult Attachment Interview (AAI), the gold standard measure of adult attachment research. These patients were extracted from a larger sample of 181 and compared to others without a U/d classification. In this paper, we discuss two different discourse styles associated with a U/d classification. Some U/d patients did not seem to sufficiently elicit the therapist's endorsement of what they said. For example, they did not justify their claims with examples or explanations, or did not consider others' intentions or experiences. Other U/d patients were credible, but left the listener uncertain as to the underlying point of their discourse, for example, by glaringly omitting the consequences of their experiences, or interrupting their narratives mid-way. In the discussion, we place these observations in the context of recent thinking on attachment and epistemic trust, and discuss how this study may form the basis for future quantitative studies of psychotherapy.

A clinical illustration of short-term mentalization-based therapy for borderline personality disorder.

OBJECTIVE: Mentalization-based therapy (MBT) is an evidence-supported, long-term psychotherapy program developed to treat borderline personality disorder (BPD). A short-term, 20-week adaptation to the original MBT format including case formulation, psychoeducation, and group and individual therapy has recently been proposed. The current case material will illustrate how the recent adaptation to the mentalization-based practice can enhance personality functioning using a short-term format. METHODS: Case material is presented to demonstrate the clinical application of short-term MBT in the treatment of a young woman diagnosed with BPD who has a history of failed treatment attempts and who showed signs of affective dysregulation, unstable relationships, and intense abandonment anxiety. RESULTS: The case illustration shows how short-term MBT can facilitate improvement in personality functioning, specifically targeting situations in which the patient lost her temper and became overwhelmed by abandonment anxiety. By continuously employing therapeutic shifts toward greater autonomy and agency, and by maintaining a balanced empathetic therapeutic stance, the therapists were able to enhance the patients mentalizing and personality functioning. CONCLUSIONS: Short-term MBT can be effectively implemented to enhance the mentalizing capacity and personality functioning in outpatients with BPD.

A Mentalizing Approach for Narcissistic Personality Disorder: Moving From "Me-Mode" to "We-Mode".

Narcissistic personality disorder (NPD) is a prevalent condition that frequently co-occurs with other diagnoses that bring patients into treatment. Narcissistic disturbances are not often the chief complaint, but they complicate the development of an adequate therapeutic alliance. Typical countertransference challenges, combined with stigma related to NPD, result in difficulty for the therapist to relate to these patients empathically. Mentalization-based treatment provides a means for therapists to reach these patients by taking a "not-knowing" stance with interest and curiosity in clarifying and expanding a shared awareness of the patient's emotional experiences. By understanding the attachment functions, mentalizing imbalances, and problems of epistemic disregard among patients with NPD, therapists can break through the self-centered "me-mode" of the therapeutic dyad, where the typical lack of engagement or power struggles prevail, to a "we-mode," where the patient and therapist are joined in attention to what happens in the patient's mind and in interactions with others.

Treating Avoidant Personality Disorder With Combined Individual Metacognitive Interpersonal Therapy and Group Mentalization-Based Treatment: A Pilot Study.

ABSTRACT: Avoidant personality disorder (AvPD) is a severe but understudied condition. The current pilot project reports data on acceptability and outcomes of a novel treatment combining biweekly individual metacognitive interpersonal therapy (MIT) and weekly mentalization-based therapy (MBT) group therapy. A total of 30 patients with AvPD were consecutively included in the program. The primary outcome was AvPD-specific personality functioning measured by self-report after treatment. Secondary outcomes were symptom distress, interpersonal problems, quality of life, and psychosocial functioning. Twenty-two patients completed treatment, with a mean duration of 13 months. On the primary outcome, effect sizes were generally moderate to large (effect size range: 0.59-1.10). On secondary outcomes, effect sizes were large (effect size range: 0.77-2.3). Both in terms of acceptability and outcomes, results are promising for the combination of MIT and MBT for AvPD. The approach is a strong candidate for further investigation in future large-scale randomized controlled trial.

Mentalizing the patient-Patient experiences with short-term mentalization-based therapy for borderline personality disorder: A qualitative study.

Background: Mentalization-based therapy (MBT) is an evidence-supported psychotherapy approach for borderline personality disorder (BPD) that has been implemented in mental health services worldwide. Originally, MBT was developed as an 18-months program for BPD. However, a short-term (5 months) MBT program has been developed. Research into patient experiences with long-term MBT for BPD is scarce, and no studies have investigated patient experience with short-term MBT for BPD. Objective: The objective of this study was to explore patient experience with short-term MBT for BPD in the Danish mental health services. Methods: Semi-structured qualitative interviews were conducted with 12 outpatients diagnosed with BPD, who attended short-term MBT for 5 months. The interviews were verbatim transcribed and analyzed using thematic analysis with double coding. Results: The analysis resulted in four subordinate themes: (1) Treatment duration - too short or appropriately short?, (2) The group as a "safe space," (3) Bad experiences impacted treatment negatively, and (4) My life has changed for the better. Conclusion: The results suggest that most of the patients were overall satisfied with short-term MBT, which they experienced as having a positive impact on their lives. However, a subgroup of patients wanted more therapy. This study highlighted the strengths and limitations of short-term MBT for BPD as experienced by the patients, and points to barriers in developing service-user informed short-term treatment options for BPD.

Detailed statistical analysis plan for the short-term versus long-term mentalisation-based therapy for outpatients with subthreshold or diagnosed borderline personality disorder randomised clinical trial (MBT-RCT).

BACKGROUND: Psychotherapy for borderline personality disorder is often extensive and resource-intensive. Mentalisation-based therapy is a psychodynamically oriented treatment option for borderline personality disorder, which includes a case formulation, psychoeducation, and group and individual therapy. The evidence on short-term compared with long-term mentalisation-based therapy is currently unknown. METHODS/DESIGN: The Short-Term MBT Project (MBT-RCT) is a single-centre, parallel-group, investigator-initiated, randomised clinical superiority trial in which short-term (20 weeks) will be compared with long-term (14 months) mentalisation-based therapy for outpatients with subthreshold or diagnosed borderline personality disorder. Outcome assessors, data managers, the data safety and monitoring committee, statisticians, and decision-makers will be blinded to treatment allocation. Participants will be assessed before randomisation and at 8, 16, and 24 months after randomisation. The primary outcome will be the severity of borderline symptomatology assessed with the Zanarini Rating Scale for Borderline Personality Disorder. Secondary outcomes will be functional impairment (Work and Social Adjustment Scale), quality of life (Short-Form Health Survey 36-mental component), global functioning (Global Assessment of Functioning), and proportion of participants with severe self-harm. In this paper, we present a detailed statistical analysis plan including a comprehensive explanation of the planned statistical analyses, methods to handle missing data, and assessments of the underlying statistical assumptions. Final statistical analyses will be conducted independently by two statisticians following the present plan. DISCUSSION: We have developed this statistical analysis plan before unblinding of the trial results in line with the Declaration of Helsinki and the International Conference on Harmonization of Good Clinical Practice Guidelines, which should increase the validity of the MBT-RCT trial by mitigation of analysis bias. TRIAL REGISTRATION: ClinicalTrials.gov NCT03677037 . Registered on 19 September 2018.

Incorporating narrative repair in the treatment of avoidant personality disorders: A case in point.

Avoidant personality disorder (AvPD) is characterized by multiple struggles, including shyness, feelings of inadequacy, and hypersensitivity to interpersonal judgments. Research indicates that people with AvPD also show disturbances in narrative identity, which is an internal and evolving story created about the personal past, present, and presumed future. Here, the novel Guide for Narrative Repair (GNaR) recently developed by (Thomsen et al., 2020) is introduced as a potentially useful tool to help people with AvPD in crafting more adaptive narrative identities. The guide is brought to life via a case study analysis of Adam, a male outpatient suffering from AvPD. Consistent with the GNaR, disturbances in Adam's storied self are brought to light and ways to facilitate his narrative repair are proposed. We conclude with implications related to the case as well as the potential narrative turn in AvPD treatment.

Awakening to recognize the detrimental effects of social avoidance and the possibility of healing through reconnection.

BACKGROUND: Loneliness and social avoidance are widespread and serious mental health problems. People experiencing loneliness or social avoidance have difficulties maintaining ordinary life activities and often experience profound suffering. How do we as clinicians deal with or help people out of loneliness and social avoidance? AIMS: In this paper, we introduce the issue on loneliness and social avoidance. We do so by first defining loneliness and social avoidance and outlining the impact on mental health issues of these phenomena. Next, we introduce the six papers central to the special issue along with some thoughts on how to understand therapy and treatment of social avoidance. DISCUSSION: We discuss new directions and how to move beyond more conventional therapeutic approaches to these problems.

Personality Functioning and Mentalizing in Patients With Subthreshold or Diagnosed Borderline Personality Disorder: Implications for ICD-11.

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.

How does level of personality functioning inform clinical management and treatment? Implications for ICD-11 classification of personality disorder severity.

PURPOSE OF REVIEW: The International Classification of Diseases, 11th Edition (ICD-11) classifies personality disturbance according to levels of severity. This article reviews the literature on levels of personality functioning in relation to clinical management and treatment, and proposes how these findings apply to the ICD-11 classification of personality disorders. RECENT FINDINGS: Findings were primarily derived from studies using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) Level of Personality Functioning Scale (LPFS), Kernberg's Level of Personality Organization, and the general P-factor of personality disorder. Severity of personality dysfunction is related to treatment outcome, risk of dropout, therapeutic alliance, readiness for treatment, risk of harm to self or others, risk of dissociation and psychotic-like breaks, coherence in narrative identity, reflective functioning, and epistemic trust. SUMMARY: The overall level of personality disorder severity indicates risk of negative outcomes and may be used as decision tool for 'personalized medicine' and required treatment intensity (e.g., strength of alliance and the need for establishing epistemic trust). Beyond the ICD-11 guidelines for determining personality disorder severity, these implications also apply to practitioners using comparable frameworks such as the DSM-5 LPFS and Kernberg's Level of Personality Organization. Future research should focus on the interaction of severity with trait qualifiers in relation to clinical management.

Level of alexithymia as a measure of personality dysfunction in avoidant personality disorder.

BACKGROUND AND OBJECTIVES: Avoidant Personality Disorder (AvPD) is considered a mild to moderate personality disorder. However, few studies have focused on the heterogeneity of AvPD in terms of symptoms and severity. In the current study we set out to replicate and extend earlier findings showing that there is variation among patients with AvPD in terms of alexithymia and, further, that this variation is especially associated with specific facets of personality functioning and is not explained by measures of depression, symptom severity, or co-occurring personality disorder traits. METHOD: We used intake data from a sample of AvPD patients (n = 56) who had been treated in similar outpatient services. Alexithymia was measured using the Toronto Alexithymia Scale (TAS-20). Patients filled out questionnaires that were analysed using linear regression models. RESULTS AND CONCLUSIONS: Using well-established cut-off points for low, intermediate and high levels of alexithymia we found an almost equal distribution of alexithymia groups in our sample. Alexithymia was associated with higher personality dysfunction on twelve out of sixteen facets of personality functioning. For eight of these personality facets the alexithymia total score explained significant variance even after controlling for self-reported depression, symptom severity and clinician ratings of personality disorder. Results suggest that AvPD is heterogeneous and that alexithymia may be important as an indicator of severity of specific personality dysfunction.
