Specialized Treatment for Patients with Severe Avoidant Personality Disorder: Experiences from Scandinavia

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.

Group schema therapy versus group cognitive behavioral therapy for patients with social anxiety disorder and comorbid avoidant personality disorder: A randomized controlled trial

BACKGROUND

Patients with social anxiety (SAD) and comorbid avoidant personality disorder (AVPD) are severely impaired. Group cognitive behavioral therapy (GCBT) is considered an effective treatment for SAD. More knowledge on treatment of SAD with comorbid AVPD is needed. Schema therapy, developed for personality and chronic mental disorders, may be a promising treatment.

METHODS

We conducted a randomized controlled trial in an outpatient population (n = 154) with both SAD and AVPD. Group Schema Therapy (GST) and GCBT were compared on SAD symptoms (Liebowitz Social Anxiety Scale) and manifestations of AVPD (Avoidant Personality Disorder Severity Index).

RESULTS

Intention-to-treat analysis showed no significant differences between treatments at 3 months post-treatment and one-year follow-up. Both modalities led to significant and substantial improvements. No significant between-differences were found in depressive symptoms (Inventory of Depressive Symptoms) and quality of life (World Health Organization Quality of Life-BREF). Per-protocol analysis showed similar outcomes and no significant differences in recovery from SAD and AVPD. Significantly more patients completed GST.

CONCLUSION

GST and GCBT are valuable treatments for SAD with comorbid AVPD. The higher treatment retention in ST indicates ST is more acceptable than GCBT. Future studies should focus on enhancing treatment effects and improving retention to GCBT.

Examining the relationship between social withdrawal motivations and symptoms of hikikomori

Objective: This study aimed to examine the association between social withdrawal motivations (peer isolation, shyness, unsociability, low mood, and avoidance) and symptoms of hikikomori using both variable- and person-oriented analyses.Method: Adolescents (N = 212) participated in this cross-sectional study. Data were collected using the Social Withdrawal Motivations Scale and the Avoidance subscale of the Child Social Preference Scale-Revised, the 25-item Hikikomori Questionnaire, the Personality Inventory for the DSM-5 Brief Form, and the Interpersonal sensitivity subscale of the Brief Symptom Inventory.Results: Path analysis revealed that peer isolation, shyness, unsociability, and avoidance were associated with symptoms of hikikomori while covarying for age, sex, maladaptive personality, and interpersonal sensitivity. Cluster analysis based on social withdrawal motivations identified four subtypes of adolescents. The group with high social withdrawal motivations showed the highest level of overall personality dysfunction and interpersonal sensitivity. Additionally, the group with high social withdrawal motivations and the group with high avoidance demonstrated higher symptoms of hikikomori compared to the other two groups, after accounting for the effects of the covariates.Conclusions: The findings highlight that the evaluation of co-occurrent social withdrawal motivations may improve the ability to identify those adolescents most in need of support.

Agency in avoidant personality disorder: a narrative review

Objectives

Avoidant personality disorder (AvPD) is a highly prevalent personality disorder, especially in clinical settings, yet scarcely researched. People diagnosed with AvPD have severe impairments in functioning and suffer greatly, yet we still lack meta-analytic evidence for therapy and only a few RCTs are conducted. Patient factors are the most important for outcome in therapy, in general. Lack of agency might be a core deficit in people diagnosed with AvPD. Their conditions might be improved if we understand their agency better. We review previous research regarding psychological mechanisms and interpersonal relationships that facilitate or hinder agency in AvPD in daily life and psychotherapy.

Methods

Summarizing original literature in a narrative review with reflexive thematic analysis.

Results

People diagnosed with AvPD seem to have significant impairments in their sense of agency due to a lack of emotional awareness, an overweight of inhibiting vs. activating emotions, and difficulties regulating emotions. Difficulties also seem related to high levels of attachment avoidance and fear, creating strong ambivalence in social needs, in addition to a strong tendency to subordinate to others. A weak sense of self with a poor narrative, self-doubt, and harsh self-critique makes a reflexive and intentional stand increasingly difficult for these people.

Conclusion

This review gives a clinically meaningful understanding of core strengths and deficits in the personality functioning of AvPD that can help clinicians map out important therapeutic work, identify barriers to client-agency in therapy, and work through relational difficulties in the therapeutic alliance.

A Preliminary Study of the Interactive Effect of Avoidant Personality Disorder Symptoms and Expressive Suppression on the Outcome of a Psychodynamically Oriented Day Treatment Program

Introduction: Patients with avoidant personality disorder (AvPD) pathology tend to have poor prognosis in psychotherapy, yet there has been little research conducted to better understand why their outcomes are limited, making it difficult to improve treatments for them. Expressive suppression is a dysfunctional emotion regulation strategy that may exacerbate avoidant tendencies, further complicating the therapeutic process. Methods: Using data from a naturalistic study (N = 34) of a group-based day treatment program, we examined whether there was an interactive effect of AvPD symptoms and expressive suppression on treatment outcome. Results: Findings revealed a significant moderating effect of expressive suppression on the association between AvPD symptoms and treatment outcome. The outcome for patients with more severe AvPD symptoms was particularly poor when they engaged in high levels of expressive suppression. Discussion: The findings suggest that the combination of significant AvPD pathology and high expressive suppression is associated with poorer responsiveness to treatment.

Cross-walking personality disorder types to ICD-11 trait domains: An overview of current findings

The ICD-11 has adopted a classification of Personality Disorders (PD) that abolishes the established categorical PD types in favor of global severity classification with specification of individual trait domains. To facilitate and guide this profound transition, an overview of current research on empirical associations between established PD types and ICD-11 trait domains seems warranted. We identified a total of 9 relevant studies from 2018 to 2022, which were based on both clinical and community samples from U.S., China, Brazil, Denmark, Spain, Korea, and Canada. The patterns of associations with ICD-11 trait domains were systematically synthesized and portrayed for each PD type. Findings overall showed expected and conceptually meaningful associations between categorical PD types and ICD-11 trait domains, with only few deviations. Based on these findings, we propose a cross-walk for translating categorical PD types into ICD-11 trait domains. More research is needed in order to further guide continuity and translation between ICD-10 and ICD-11 PD classification in mental healthcare, including facet-level ICD-11 trait information. Moreover, the nine reviewed studies only relied on self-reported ICD-11 trait domains, which should be expanded with clinician-rated trait domains in future research. Finally, future research should also take ICD-11's essential PD severity classification into account.

Avoidant and borderline personality disorder patients during the first Covid-19 wave in Norway - a survey-based comparison of therapy changes and patients' accommodations

BACKGROUND

Patients with personality disorders (PDs) often have insecure attachment patterns and may be especially vulnerable to abrupt treatment changes. Patients with borderline PD (BPD) are often considered vulnerable to treatment interruption due to chronic fear of abandonment. Nonetheless, other PDs are poorly investigated. In the first Covid-19 wave in Norway, in-person treatment facilities and group treatments were strongly restricted from March 12th until May/June 2020.

OBJECTIVES

To examine and compare changes in outpatient treatment for patients with avoidant (AvPD) and BPD during the first Covid-19 wave in Norway, and patients' reactions to these changes.

METHODS

The study is based on a cross-sectional survey distributed to 1120 patients referred to 12 different PD treatment units on a specialist mental health service level within the Norwegian Network for Personality Disorders. The survey included questions on treatment situation, immediate reactions, and changes during the crisis. From 133 responders (response rate 12%), 40 patients reported BPD and 30 AvPD as diagnosis.

RESULTS

All patients were followed up from their therapist after March 12th. Almost all patients in both groups expressed satisfaction under the new circumstances. Both groups experienced the same regularity as before, but more AvPD patients reported less than weekly consultations. AvPD patients reported more negative feelings about changes in therapy, and missed the therapy and group members more than the BPD group.

CONCLUSION

After the lockdown, BPD patients received a closer follow-up than AvPD patients, and the latter reported more negative feelings related to change in their treatment situation.

Metacognitive interpersonal group therapy for adolescents with avoidant personality disorder: The case of Sofia

INTRODUCTION

Early intervention studies for adolescents and early adults are required to explore the acceptability and effectiveness of psychological therapies across the full range of personality disorders (PDs) beyond just borderline PD. The main aim of the current paper was to describe a Metacognitive Interpersonal Therapy group adaptation for adolescents (MIT-GA) presenting with PDs featuring overcontrol and social inhibition, and in particular Avoidant PD characteristics.

METHODS

We report findings from a single case of a female adolescent diagnosed with Avoidant PD providing preliminary data on feasibility and the possible effectiveness of MIT-GA.

RESULTS

Evidence of acceptability and meaningful clinical gains are described.

CONCLUSIONS

Results suggest that MIT-GA could be a powerful treatment option in patients with generalized social avoidance who do not currently receive gold-standard psychotherapeutic treatments. This intervention also appears to be effective and cost-effective in initiating significant clinical changes in profiles of young patients with non-borderline PD symptoms.

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.

Prevalence, Factor Structure, and Heritability of Avoidant Personality Disorder

ABSTRACT

To review the community prevalence, factor structure, and heritability of avoidant personality disorder (AVPD), we reviewed the literature of empirical studies reported between years 1980 and 2020. Community point prevalence rates ranged from 0.8% to 5%, with one study of women older than 25 years finding a lifetime rate of 9.3%. A weighted point prevalence for studies involving both men and women was 3.3%. All factor analytic studies indicated a one factor solution. The themes were social inadequacy, feeling inferior, and fears of social rejection. Family studies of heritability for AVPD ranged from 0.18 to 0.56. Twin studies ranged from 0.28 to 0.71. The weighted average for heritability was 0.55. AVPD is an important clinical issue because it is prevalent in the community and has high morbidity and high heritability. Its single factor seems to suggest evaluation and treatment should be straightforward, but despite this, it tends to be underdiagnosed and undertreated.

Transdiagnostic conceptualization of social avoidance through the lens of personality functioning and traits

This commentary seeks to highlight how social avoidance is portrayed in the six presented case-reports from the perspective of self- and interpersonal functioning as well as stylistic trait features of negative affectivity (e.g., anxiousness and shame) and detachment (e.g., social withdrawal and emotional restriction). This approach to avoidance and social isolation will subsequently be generalized to a range of mental disorders where such features play a significant role. We propose that self and interpersonal functioning along with traits of negative affectivity and detachment may serve as a transdiagnostic framework for describing features of avoidance and social isolation across different treatment models, traditions, and disorders. We specifically assume that future developments of the promising treatment approaches presented in the current collection of case reports may benefit from such a "shared" framework for conceptualizing and treating self- and interpersonal problems related to avoidance and social isolation.

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.

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.

Lived Experience of Treatment for Avoidant Personality Disorder: Searching for Courage to Be

Objective: To inquire into the subjective experience of treatment by persons diagnosed with avoidant personality disorder.

Methods: Persons with avoidant personality disorder (n = 15) were interviewed twice, using semi-structured in-depth interviews, and the responses subject to interpretative-phenomenological analysis. Persons with first-hand experience of avoidant personality disorder were included in the research process.

Results: The super ordinate theme emerging from the interviews, “searching for courage to be” encompassed three main themes: “seeking trust, strength, and freedom,” “being managed,” and “discovering the possibility for change and development.” The main theme, “being managed,” included the subthemes: “getting a diagnosis,” “receiving medication,” and “attending therapy.”

Conclusion: Although this may not be specific to avoidant personality disorder, the findings highlight the importance of being met inter-subjectively as a person with intentionality and agency, even when one does not feel like one. The importance of establishing an emotional bond and emergent trust for open therapeutic collaboration, learning, and becoming able to build courage to begin to approach that which one fears is emphasized.
