Avoidant Personality Disorder: a Current Review

Clustering Individuals Based on Similarity in Idiographic Factor Loading Patterns

Idiographic measurement models such as p-technique and dynamic factor analysis (DFA) assess latent constructs at the individual level. These person-specific methods may provide more accurate models than models obtained from aggregated data when individuals are heterogeneous in their processes. Developing clustering methods for the grouping of individuals with similar measurement models would enable researchers to identify if measurement model subtypes exist across individuals as well as assess if the different models correspond to the same latent concept or not. In this paper, methods for clustering individuals based on similarity in measurement model loadings obtained from time series data are proposed. We review literature on idiographic factor modeling and measurement invariance, as well as clustering for time series analysis. Through two studies, we explore the utility and effectiveness of these measures. In Study 1, a simulation study is conducted, demonstrating the recovery of groups generated to have differing factor loadings using the proposed clustering method. In Study 2, an extension of Study 1 to DFA is presented with a simulation study. Overall, we found good recovery of simulated clusters and provide an example demonstrating the method with empirical data.

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.

Societal costs of personality disorders among treatment-seeking patients in Norway: the relative contribution of specific DSM-5 categories

Personality disorders (PDs) are associated with high levels of societal costs, regardless of whether a single PD or a broad range of PDs have been studied. However, research on the relative contribution of specific PD-types on societal costs is limited. The aim of this study was to explore the possible contributions of the individual DSM-5 categories of PDs on the level of societal costs and its components (health service costs and productivity loss), while controlling for the impact of comorbid mental health and substance use disorders on these outcomes. Participants (n = 798) were retrieved from the quality register of the Norwegian Network for Personality Disorders-a collaboration of PD-treatment units within specialist mental health services. The patients were referred to treatment in the time-period 2017-2020. Costs were assessed using a structured interview covering the 6-month period prior to assessment. Diagnoses were determined by semi-structured diagnostic interviews (SCID-5-PD and M.I.N.I.). Statistics included multiple regression analyses. The main result was that no specific PD had a unique contribution to the high level of societal costs generally found among treatment-seeking patients with PDs. Borderline PD (BPD) was the only PD with significantly higher health service costs than the other PDs, while BPD, avoidant PD, and unspecified PD were independently associated with enhanced productivity loss. The differential cost-effects of specific PDs on the cost components were small. Several comorbid mental health and substance use disorders were significant contributors to costs, irrespective of PD status. The results underscore the importance of developing and implementing effective treatments for a broader range of PDs, to reduce the high levels of societal costs associated with all PDs.

Dysfunctional personality beliefs and psychopathology in patients with central serous chorioretinopathy

OBJECTIVES

To assess dysfunctional personality beliefs associated with specific personality disorders (PD), as well as psychopathological symptoms and psychological distress levels in central serous chorioretinopathy (CSC) patients.

MATERIAL AND METHODS

This cross-sectional study included acute and chronic CSC patients and age- and sex-matched healthy volunteers. Dysfunctional personality beliefs and psychopathological symptoms assessed with Personality Belief Questionnaire-Short Form and Symptom Check List-90 Revised (SCL-90-R), respectively, were compared between CSC patients and healthy volunteers and between acute and chronic CSC patients.

MAIN RESULTS

Of the 55 CSC patients included in the study analysis, 21 (38.2%) had acute and 34 (61.8%) chronic CSC. Avoidant PD (13.92±3.79 vs. 12.03±3.98, P=0.012) and obsessive-compulsive PD (13.94±3.95 vs. 12.27±3.75, P=0.025) scores on the PBQ-SF were significantly higher in CSC patients than in healthy volunteers. The PBQ-SF scores were similar between acute and chronic CSC patients. CSC patients scored significantly higher on the general severity index (GSI) and all symptom dimensions except phobic anxiety and psychoticism on the SCL-90-R. In addition, scores for obsessive-compulsive, depression, interpersonal sensitivity, paranoid ideation, and GSI were significantly higher in acute than in chronic CSC patients.

CONCLUSIONS

This first study investigating the relationship between CSC and dysfunctional personality beliefs indicates that CSC patients have higher levels of dysfunctional beliefs related to avoidant and obsessive-compulsive PD than healthy volunteers. These findings present a new aspect of the personality profile of CSC patients and point to a target for intervention, i.e., dysfunctional beliefs, through a cognitive-psychiatric approach.

Brief individual experiential schema therapy in adult outpatients with cluster C personality disorders: Does it work?

This study investigated the effectiveness of brief individual experiential schema therapy (ST) in 12 adult outpatients with cluster C personality disorders (PD) using randomised multiple baseline design. Waitlist period was followed by five explorative sessions, 18 experiential ST sessions, two treatment follow-up (FU) booster sessions and a 6-month FU assessment. Overall well-being (ORS), behavioural treatment goals and negative core beliefs were assessed 60-91 times, global symptomatic distress (BSI) six times. PD severity (SCID-5-PD) was pre-post-analysed. Randomisation and non-parametric tests showed large significant effects (d = 1.08-2.38, r = .53-.66) on all outcomes at treatment-FU and 6-month FU assessment. This is the first study providing preliminary evidence of effectiveness of brief individual experiential ST for patients with cluster C PD, tentatively challenging the common tenet that long treatment duration is required. Due to limitations, replication is recommended.

Mental health disorders, functioning and health-related quality of life among extensively hospitalized patients due to severe self-harm - results from the Extreme Challenges project

Background

Severe self-harm leading to extensive hospitalization generates extreme challenges for patients, families, and health services. Controversies regarding diagnoses and health care often follow. Most evidence-based treatments targeting self-harm are designed for borderline personality disorder (BPD). However, current knowledge about mental health status among individuals with severe self-harm is limited.

Objectives

To investigate psychopathology among patients extensively hospitalized due to severe or frequent self-harming behaviors.

Method

A cross sectional study (period 2019-2021) targeting psychiatric inpatients (>18 years) with frequent (>5) or long (>4 weeks) admissions last year due to self-harm. The target sample (N = 42, from 12 hospitals across all Norwegian health regions) was compared to individuals admitted to outpatient personality disorder (PD) treatment within specialist mental health services in the same period (N = 389). Clinicians performed interviews on self-harm and psychopathology, supplemented by self-report.

Results

The target sample were young adults, mainly female, with considerable hospitalization and self-harming behaviors, both significantly more extensive than the comparison group. The majority in both groups reported self-harm onset <18 years. The target sample reported increasing severity of self-harm acts and suicidal intention over time. Both samples had high levels of childhood trauma, impaired personality functioning, and a majority fulfilled criteria for PD. In the target sample, comorbid depression, PTSD, anxiety disorders, and substance use occurred more frequently and in 50%, psychosis/dissociative disorder/autism spectrum disorder/ADHD was reported (outpatient comparison sample: 9%). 35% in the target sample screened over cut-off for possible intellectual disability. The target sample reported poor psychosocial functioning and health-related quality of life - greater impairment than the outpatient comparison sample.

Conclusion

The study reveals that severe self-harm inpatients have complex psychopathology and highlights the importance of individualized and thorough assessment among patients with severe and/or repetitive self-harm.

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.

Parental personality disorder symptoms and children's social skills: a prospective community study

Acquiring age-appropriate social skills, arguably a major prerequisite for favorable psychosocial development in children, is targeted in a range of interventions. Hence, identifying factors that limit this acquisition may inform preventative and treatment efforts. Personality disorders are characterized by pervasive and enduring dysfunctional interpersonal functioning, including parenting, and could thus entail risk for offspring in not developing adaptive interpersonal skills. However, no study has tested this possibility. A representative sample drawn from two birth cohorts of Norwegian 4-year-olds (n = 956) and their parents was followed up at ages 6, 8, and 10 years. Parents' personality disorder symptoms were measured dimensionally with the DSM-IV and ICD-10 Personality Questionnaire, and children's social skills were evaluated by the Social Skills Rating System. A difference-in-difference approach was applied to adjust for all unmeasured time-invariant confounders, and parental symptoms of depression and anxiety were entered as covariates. Increased Cluster B symptoms in parents of children aged 4 to 6 years predicted decreased social skill development in offspring (B = -0.97, 95% CI -1.58, -0.37, p = 0.002). On a more granular level, increased symptoms of borderline (B = -0.39, CI -0.65, -0.12, p = 0.004), histrionic (B = -0.55, CI -0.99, -0.11, p = 0.018), and avoidant (B = -0.46, CI-0.79, -0.13, p = 0.006) personality disorders in parents predicted decreased social skill development in offspring. Subclinical levels of borderline, histrionic and avoidant personality disorders in parents may impair the development of social skills in offspring. Successfully treating these personality problems or considering them when providing services to children may facilitate children's acquisition of social skills.

Comparison of Cognitive Behavioral Therapy and Cognitive Behavioral Group Therapy in the Treatment of Avoidant Personality Disorder

The primary aim of this study is to compile studies on cognitive behavioral therapy method in the treatment of avoidant personality disorder and present their data. Another aim is to discuss with the reasons, cognitive behavior group therapies may be more effective on this disorder than cognitive behavioral individual therapies, since the main problem in avoidant personality disorder stems from interpersonal communication and because the cognitive behavioral therapies applied as a group were found to be quite effective when the avoidant personality disorder was first defined. The aim of this study is to present recommendations together and to compile studies in which cognitive behavioral group therapies were applied on avoidant personality disorder. In this study, studies in domestic and foreign sources, which were conducted with a sample group with avoidant personality disorder and social anxiety disorder, were examined and the study was prepared by reviewing the literature, which is one of the secondary data collection techniques. Since there are not many studies on avoidant personality disorder in the literature, considering the high similarity and comorbidity of avoidant personality disorder with social anxiety disorder, studies on cognitive behavioral group therapies related to social anxiety disorder have also been compiled. As a result of the studies examined, it has been found that the symptoms of avoidant personality disorder are related to the distorted cognition of individuals and cognitive behavioral therapies are a very effective approach because they increase the awareness of the automatic thoughts in the minds of the clients, question their correctness and provide alternative thoughts to replace them.

Combined group and individual therapy for patients with avoidant personality disorder-A pilot study

Objective

Avoidant personality disorder (AvPD) is a common disorder within mental health services, associated with significant psychosocial impairment. The disorder has been neglected in research. There are currently no evidence-based treatments for AvPD, and there is a need for treatment studies focusing particularly on this form of personality pathology. The present study was a pilot study of combined group and individual therapy for patients with AvPD, based on mentalization-based and metacognitive interpersonal therapy. The aim was to investigate the feasibility of the treatment program and the course of symptoms and personality functioning during treatment and 1-year follow-up.

Methods

The study included 28 patients. Clinical evaluation at baseline comprised structured diagnostic interviews and patients' self-report of symptoms, psychosocial function, interpersonal problems, personality functioning, alexithymia, self-esteem, attachment style, therapeutic alliance, and client satisfaction. Patients' self-report were repeated at the end of treatment and 1-year follow-up.

Results

The drop-out rate was 14%. Average treatment length among the 22 treatment completers was 17 months. Mean levels of therapeutic alliance and client satisfaction were satisfactory. Effect sizes were large for global symptom distress, depression, anxiety, and psychosocial adjustment, and in the moderate range for aspects of personality functioning. Yet, the results showed a wide range of outcomes among the patients.

Conclusions

This pilot study shows promising results for combined group- and individual therapy for AvPD patients with moderate to severe impairment. Larger scale studies should be conducted to increase empirically based knowledge to guide development of differentiated treatments adapted to patients' various levels of AvPD severity and profiles of personality dysfunction.

The development of narrative identity in the psychodynamic treatment of avoidant personality disorder: A case study

Avoidant personality disorder (AvPD) is characterized by feelings of shyness, inadequacy, and restraint in intimate relationships and has been associated with a disturbance in narrative identity, which is the internalized and evolving story of past, present, and future experiences. Study findings have indicated that an improvement in overall mental health through psychotherapy may increase narrative identity. However, there is a lack of studies incorporating not only the examination of narrative identity development before and after psychotherapy but also within psychotherapy sessions. This case study examined the development of narrative identity in short-term psychodynamic psychotherapy treatment of a patient with AvPD, using therapy transcripts and life narrative interviews before, after, and 6 months following treatment termination. Narrative identity development was assessed in terms of agency, communion fulfillment, and coherence. Results showed that the patient’s agency and coherence increased over the course of therapy, whereas communion fulfillment decreased. At the six-month follow-up, agency and communion fulfillment increased, whereas coherence remained stable. The results of this case study suggest that the patient’s sense of narrative agency and ability to narrate coherently improved after undergoing short-term psychodynamic therapy. The decrease of communion fulfillment during psychotherapy and later increase after termination suggests that the patient became more aware of conflictual patterns in their relationships, therefore realizing that their wishes and desires were not being fulfilled in their current relationships. This case study displays the possible impact short-term psychodynamic therapy may have by helping patients with AvPD develop a narrative identity.

Motive-Specific Affective Contingencies and Their Relevance for Personality and Motivated Behavior

Individuals differ in the tendency to derive pleasure out of motive-specific incentives, such as being socially included or attaining power. Multiple theoretical approaches have proposed that such motive-specific positive affective contingencies (PACs) are central building blocks of motive dispositions and personality more broadly. In the current research, we put this claim to test and investigated individual differences with regard to motive-specific PACs in the affiliation and power domains. We measured PACs via spontaneous emotional reactions to motive-specific cues, as assessed by affect ratings and electromyographic (EMG) recordings of smile responses. Both of these PAC operationalizations were highly internally consistent and moderately to highly stable across time. Furthermore, motive-specific PACs were linked in a manner consistent with theory to measures of motive dispositions and to personality traits with motivational underpinnings (i.e., extraversion, agreeableness, and narcissism). Finally, in the affiliation domain, motive-specific PACs were linked to objectively assessed, key motivational outcomes (i.e., attentional orientation, behavior in daily life, and in the laboratory). Taken together, the findings underscore the relevance of affective contingencies for the understanding of personality and motivated behavior.

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.

Avoidant Personality Disorder Symptoms and Cardiovascular Reactivity to Psychological Stress Tasks With Increasing Cognitive Demands

Abstract. This study aimed to investigate whether and how avoidant personality disorder symptoms are related to cardiovascular reactivity to stress tasks with different levels of cognitive demands. The revised Chinese edition of the avoidant personality disorder subscale of Personality Diagnosed Questionnaire-4+ (PDQ-4+) was administered to 222 undergraduate students randomly assigned to psychological stress tasks (i.e., mental arithmetic tasks) with low, moderate, or high cognitive demands (manipulated by task difficulty), during which their physiological data were continuously collected. Results showed that avoidant personality disorder symptoms and cognitive demands of tasks interactively predicted systolic blood pressure (SBP) and diastolic blood pressure (DBP) reactivity. In specific, avoidant personality disorder symptoms were not associated with SBP reactivity under the low- and moderate-demand conditions and DBP reactivity under the low-demand condition but were associated with blunted SBP reactivity under the high-demand condition and blunted DBP reactivity under the moderate- and high-demand conditions. These findings indicate that the association between avoidant personality disorder symptoms and cardiovascular reactivity to psychological stress is contingent on the cognitive demands of tasks, which have potential implications for physical health.

The ICD-11 classification of personality disorders: a European perspective on challenges and opportunities

The 11th revision of the World Health Organization (WHO) International Classification of Diseases (ICD-11) includes a fundamentally new approach to Personality Disorders (PD). ICD-11 is expected to be implemented first in European countries before other WHO member states. The present paper provides an overview of this new ICD-11 model including PD severity classification, trait domain specifiers, and the additional borderline pattern specifier. We discuss the perceived challenges and opportunities of using the ICD-11 approach with particular focus on its continuity and discontinuity with familiar PD categories such as avoidant PD and narcissistic PD. The advent of the ICD-11 PD classification involves major changes for health care workers, researchers, administrators, and service providers as well as patients and families involved. The anticipated challenges and opportunities are put forward in terms of specific unanswered questions. It is our hope that these questions will stimulate further research and discussion among researchers and clinicians in the coming years.

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.

Loneliness in Personality Disorders

PURPOSE OF REVIEW

Loneliness is a common experience in patients with personality disorders (PDs) that are characterized by impairment in self (identity, self-direction) and interpersonal functioning (empathy, intimacy). Here, we review studies assessing the association of loneliness with PD or PD traits including DSM-5's Alternative Model of PD (AMPD).

RECENT FINDINGS

The number of loneliness studies varied greatly among different PDs with most studies conducted in borderline PD. Across PDs, loneliness was associated with the severity of psychopathological symptoms and with several AMPD trait domains. Consequently, loneliness may contribute to PD severity and further impair personality functioning. Loneliness and PD share intra- and interpersonal factors (i.e., increased rejection sensitivity, information processing biases, social withdrawal) and common origins in childhood maltreatment that may explain their close association. Future research needs to investigate mechanisms on how loneliness and core characteristics of PD mutually reinforce each other in order to therapeutically address loneliness in PD.

Psychiatric Assessment of Social Impairment Across the Lifespan

Although autism spectrum disorder (ASD) is the prototypical psychiatric disorder of social impairment, several if not most psychiatric disorders are characterized by prominent impairments in social functioning. A challenge in clinically assessing and describing social impairment is that it has been variably defined and can be difficult to measure. In this article we consider the psychiatric differential diagnosis of social impairment within the DSM-5 framework. We describe the features of social impairment in 13 DSM-5 disorders from a developmental perspective and highlight diagnostic factors that differentiate among the disorders, including the main features of social impairment, verbal communication, nonverbal communication, course of social impairment, social cognition, and key features of accompanying neuropsychiatric symptoms. We conclude by describing an approach for assessing social impairment across the lifespan.

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.

Vulnerability of personality disorder during COVID-19 crises: a multicenter survey of mental and social distress among patients referred to treatment

BACKGROUND

Relational and emotional problems, dysregulation, self-harming or substance abuse often characterize personality disorders (PD). In Norway, COVID-19 restrictions led to an abrupt shutdown of services from 12 March 2020 also including specialized PD treatments.

AIMS

The objective of this study was to investigate social and mental distress among patients with PDs during the first COVID-19 wave.

DESIGN

A survey was distributed after the first COVID-19 wave (June-October 2020) among 1120 patients from 12 PD treatment units.

RESULTS

The response rate was 12% (N = 133). The survey reflected impairment of occupational activity (53% <50% activity last 6 months), life quality (EQ-5D-VAS: 56, SD 19), and personality functioning (LPFS-BF ≥12: 81%, 35% avoidant PD, 44% borderline PD) and high levels of depression and anxiety (PHQ-9 ≥ 10: 84%, GAD-7 ≥ 10: 68%), 49% with health-related anxiety. Problem increase was reported for anxiety (28%), depression (24%), aggression (23%), substance use (14%), and 70% of parents had more child-care difficulties. Self-destructive behaviors (26%) did not increase. The majority (78%) reported increased or unchanged social isolation and loneliness. Occupational activity declined with negative effects on part-time jobs/rehabilitation. Therapist contact was mainly telephone-based (63% ≥ weekly contact). More severe personality problems, current depressive symptoms, and self-harming before 12 March were associated with more frequent consultations.

CONCLUSION

The survey confirms severe, enhanced levels of mental distress among patients receiving telephone-based consultations as the main alternative to specialized PD treatment during the COVID-19 shutdown. The most vulnerable patients received more frequent consultations and self-destructive actions did not increase.

A review and conceptual model of the association of Type D personality with suicide risk

The role of personality as distal risk factor for suicidal thoughts and behavior is still unclear. This review aims to propose two conceptual models that explain the psychological plausibility of Type D personality as distal risk factor and contributor to the transition from general to suicide distress. To support this aim, we performed a systematic review of existing studies on the association between Type D personality and suicidal distress. A systematic search yielded eight studies that reported on Type D personality and suicidal distress. Type D personality was robustly associated with suicidal thoughts and behaviors, across populations and countries. Type D was related to the level/frequency of suicidal ideation in seven studies, and suicide attempt in two studies. Our first theoretical model identifies intra-psychic (depression, alcohol misuse, posttraumatic stress) and interpersonal (low belonging, social isolation, lack of support) vulnerabilities of individuals with Type D that may fuel the development of suicidal thoughts and behaviors. Type D by itself will not account for why people become suicidal, but our second theoretical model suggests that the avoidant-passive tendencies of Type D individuals may result in persistent problem-solving deficits, and, eventually, feelings of entrapment that may contribute to the desire to escape from pain. We conclude that empirical evidence supports the hypothesized link between Type D personality, and suicidal thoughts and behaviors. Our conceptual models - albeit often supported by indirect evidence - further substantiate the plausibility of this link, and offer concrete guidance for future studies. Primarily, more longitudinal research is necessary.

Clinical Efficacy and Cost-Effectiveness of Imagery Rescripting Only Compared to Imagery Rescripting and Schema Therapy in Adult Patients With PTSD and Comorbid Cluster C Personality Disorder: Study Design of a Randomized Controlled Trial

Background: Posttraumatic stress disorder (PTSD) is a serious and relatively common mental disorder causing a high burden of suffering. Whereas evidence-based treatments are available, dropout and non-response rates remain high. PTSD and Cluster C personality disorders (avoidant, dependent or obsessive-compulsive personality disorder; CPD) are highly comorbid and there is evidence for suboptimal treatment effects in this subgroup of patients. An integrated PTSD and CPD treatment may be needed to increase treatment efficacy. However, no studies directly comparing the efficacy of regular PTSD treatment and treatment tailored to PTSD and comorbid CPD are available. Whether integrated treatment is more effective than treatment focused on PTSD alone is important, since (1) no evidence-based guideline for PTSD and comorbid CPD treatment exists, and (2) treatment approaches to CPD are costly and time consuming. Present study design describes a randomized controlled trial (RCT) directly comparing trauma focused treatment with integrated trauma focused and personality focused treatment. Methods: An RCT with two parallel groups design will be used to compare the clinical efficacy and cost-effectiveness of "standalone" imagery rescripting (n = 63) with integrated imagery rescripting and schema therapy (n = 63). This trial is part of a larger research project on PTSD and personality disorders. Predictors, mediators and outcome variables are measured at regular intervals over the course of 18 months. The main outcome is PTSD severity at 12 months. Additionally, machine-learning techniques will be used to predict treatment outcome using biopsychosocial variables. Discussion: This study protocol outlines the first RCT aimed at directly comparing the clinical efficacy and cost-effectiveness of imagery rescripting and integrated imagery rescripting and schema therapy for treatment seeking adult patients with PTSD and comorbid cluster C personality pathology. Additionally, biopsychosocial variables will be used to predict treatment outcome. As such, the trial adds to the development of an empirically informed and individualized treatment indication process. Clinical Trial registration: ClinicalTrials.gov, NCT03833531.

Social anxiety disorder and avoidant personality disorder from an interpersonal perspective

OBJECTIVES

The general objective of this article is to study the unclear and overlapping relationship between social anxiety disorder (SAD) and avoidant personality disorder (AvPD) from an interpersonal perspective. The first specific objective is to compare the disorders with regard to interpersonal problems and general symptom distress. The second specific objective is to examine interpersonal subgroups and pathoplasticity.

DESIGN

In a cross-sectional design, patients from an outpatient psychotherapy clinic diagnosed with social anxiety disorder (SAD, n = 299), avoidant personality disorder (AvPD, n = 180), or the comorbid condition of both disorders (AvPD + SAD, n = 29) were assessed before treatment.

METHODS

Patients filled out the Inventory of Interpersonal Problems (IIP-64) and the Symptom Checklist-Revised (SCL-R-90) before treatment.

RESULTS AND CONCLUSIONS

From an interpersonal perspective, the relationship between the diagnostic groups is well described by the severity continuum hypothesis, with similar interpersonal problems related to Nonassertiveness and lower levels of general interpersonal stress in the SAD group compared to the two AvPD groups. However, other differences in severity do not fit the severity continuum hypothesis, as there are no differences in severity on the global severity index, and, moreover, the SAD group has the most severe problems on the SCL-90 phobic anxiety scale. Interpersonal pathoplasticity is not found in the diagnostic groups or in the full sample. However, three interpersonal subgroups are identified in the full sample, designated as Nonassertive, Friendly-submissive, and Cold-submissive. Implications for treatment are discussed.

PRACTITIONER POINTS

SAD is characterized by a lower level of interpersonal distress compared to AvPD, but the two disorders are similar in having Nonassertiveness as their general interpersonal problem. Contrary to expectation, SAD and AvPD did not differ in general level of symptom severity, and patients with SAD reported more problems with phobic anxiety than AvPD patients did. When understanding SAD and AvPD as different conceptualizations of the same disorder and analysing all patients together, three distinct interpersonal subgroups emerge, which can be identified as Nonassertive, Friendly-submissive, and Cold-submissive.

Comparing the interpersonal profiles of obsessive-compulsive personality disorder and avoidant personality disorder: Are there homogeneous profiles or interpersonal subtypes?

Previous studies have shown that individuals with personality disorder (PD) suffer from significant interpersonal distress. Some PDs, such as avoidant personality disorder (AvPD), have been characterized with a clear homogeneous interpersonal profile. Other PDs, such as obsessive-compulsive personality disorder (OCPD), have shown significant heterogeneity rather than a distinct profile. Our study aimed to compare these two PDs and determine their interpersonal profiles. Analyses included 43 patients with OCPD and 64 with AvPD recruited in 2 clinical trials. They completed the Inventory of Interpersonal Problems at baseline (Alden, Wiggins, & Pincus, 1990). Structural summary and circular statistic methods were used to examine group interpersonal profile. Cluster analysis was used to identify subtypes within the OCPD and AvPD samples. The AvPD sample demonstrated a homogeneous interpersonal profile placed in the socially avoidant octant of the circumplex. In contrast, the OCPD group exhibited a heterogeneous interpersonal profile, with two subtypes on opposite sides of the circumplex: (a) "aggressive" (i.e., vindictive-domineering) and (b) "pleasing" (i.e., submissive-exploitable). Both clusters demonstrated homogeneous, prototypical, and distinct interpersonal profiles. Our findings show that individuals with either OCPD or AvPD exhibit significant interpersonal distress. Although AvPD may be inherently an interpersonal PD, OCPD cannot classified into one homogenous profile, but rather two distinct interpersonal subgroups. The heterogeneity may be explained by the presence of interpersonal subtypes. Detection of subtypes can inform future research on treatment targets as well as personalized interventions, tailored to patients' specific interpersonal difficulties.

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.

The Sensitivity to Threat and Affiliative Reward (STAR) model and the development of callous-unemotional traits

Research implicates callous-unemotional (CU) traits (i.e., lack of empathy, prosociality, and guilt, and reduced sensitivity to others' emotions) in the development of severe and persistent antisocial behavior. To improve etiological models of antisocial behavior and develop more effective treatments, we need a better understanding of the origins of CU traits. In this review, we discuss the role of two psychobiological and mechanistic precursors to CU traits: low affiliative reward (i.e., deficits in seeking out or getting pleasure from social bonding and closeness with others) and low threat sensitivity (i.e., fearlessness to social and non-social threat). We outline the Sensitivity to Threat and Affiliative Reward (STAR) model and review studies that have examined the development of affiliative reward and threat sensitivity across animal, neuroimaging, genetic, and behavioral perspectives. We next evaluate evidence for the STAR model, specifically the claim that CU traits result from deficits in both affiliative reward and threat sensitivity. We end with constructive suggestions for future research to test the hypotheses generated by the STAR model.

The Differential Profile of Social Anxiety Disorder (SAD) and Avoidant Personality Disorder (APD) on the Basis of Criterion B of the DSM-5-AMPD in a College Sample

BACKGROUND

The present study was conducted to determine the differential profile of social anxiety disorder (SAD) and avoidant personality disorder (APD) based on dimensional diagnosis in criterion B of the DSM-5 Alternative Model for Personality Disorders (DSM-5-AMPD) in a college sample.

METHODS

Samples of this cross-sectional study included 320 (23.08 ± 2.66 years; 57% female) college students in western Iran during February 2015 to December 2017. Liebowitz-social anxiety scale, PID-5, SCID-II, SCID-II-SQ and diagnostic interview for SAD were the tools. The data were analysed using Pearson correlation and multiple linear regression analysis.

RESULTS

Forty-three and 38 participants met criteria for SAD alone and APD, respectively. Five main domains of PID-5 could explain 29% and 54% of the variance of SAD and APD, respectively. Facets of negative affect, detachment, antagonism, disinhibition, and psychoticism could explain 25% versus 43%, 26% versus 54%, 7% versus 27%, 21% versus 41%, 13% versus 30% of the variance of SAD and APD, respectively.

CONCLUSION

SAD and APD probably refer to two distinct mental states having prominent anxiety, emotional instability, and interpersonal pattern of avoidance and detachment of challenge. SAD is a simple form of mental disturbances with anxiety in its core features; although, APD is possibly referring to more complicated psychopathology.

Symptoms, course of Illness, and comorbidity as predictors of expressed emotion in bipolar disorder

High levels of expressed emotions (EE) reflect the amount of criticism and/or over-involvement in families and has been linked to relapse risk in various psychiatric disorders including bipolar disorder (BD). Less clear is which factors contribute to the development and/or maintenance of EE. Therefore, we tested whether patient characteristics, specifically clinical features and personality disorder traits in BD predicted key aspects of EE as assessed by patients and their relatives. Patients with remitted BD and their relatives were asked to complete the Family Attitude Scale (FAS) and the Perceived Criticism Measure (PCM). Patient characteristics were assessed with a variety of measures including SCID I and II. The FAS and PCM shared 25% of the variance for patients and 14% for relatives, suggesting a conceptual overlap, but they may not assess identical constructs. The number of previous mood episodes, current self-rated manic symptoms, and comorbid symptoms of Cluster C personality disorder predicted patient-rated FAS. Relative-rated FAS was only predicted by comorbid symptoms of Cluster A personality disorder. In BD, specific patient characteristics seem to be linked to key aspects of EE even when in remission. However, it might depend whether the patient, his/her relative, or a neutral observer assessed EE.

European guidelines for personality disorders: past, present and future

Personality disorders (PD) are common and burdensome mental disorders. The treatment of individuals with PD represents one of the more challenging areas in the field of mental health and health care providers need evidence-based recommendations to best support patients with PDs. Clinical guidelines serve this purpose and are formulated by expert consensus and/or systematic reviews of the current evidence. In this review, European guidelines for the treatment of PDs are summarized and evaluated. To date, eight countries in Europe have developed and published guidelines that differ in quality with regard to recency and completeness, transparency of methods, combination of expert knowledge with empirical data, and patient/service user involvement. Five of the guidelines are about Borderline personality disorder (BPD), one is about antisocial personality disorder and three concern PD in general. After evaluating the methodological quality of the nine European guidelines from eight countries, results in the domains of diagnosis, psychotherapy and pharmacological treatment of PD are discussed. Our comparison of guidelines reveals important contradictions between recommendations in relation to diagnosis, length and setting of treatment, as well as the use of pharmacological treatment. All the guidelines recommend psychotherapy as the treatment of first choice. Future guidelines should rigorously follow internationally accepted methodology and should more systematically include the views of patients and users.

Comorbidity in social anxiety disorder: diagnostic and therapeutic challenges

Comorbid disorders are highly prevalent in patients with social anxiety disorder, occurring in as many as 90% of patients. The presence of comorbidity may affect the course of the disease in several ways such as comorbidity in patients with social anxiety disorder (SAD) is related to earlier treatment-seeking behavior, increased symptom severity, treatment resistance and decreased functioning. Moreover, comorbidities cause significant difficulties in nosology and diagnosis, and may cause treatment challenges. In this review, major psychiatric comorbidities that can be encountered over the course of SAD as well as comorbidity associated diagnostic and therapeutic challenges will be discussed.

Mentalization-based treatment or psychodynamic treatment programmes for patients with borderline personality disorder - the impact of clinical severity

OBJECTIVES

Mentalization-based treatment (MBT), originally designed for patients with borderline personality disorder (BPD), may be particularly indicated for severe conditions. However, there is limited documentation of how increasing severity of personality disorder (PD) effect outcomes of highly specialized treatments. This study aimed to investigate associations between clinical severity and outcomes for patients in MBT as compared to a psychodynamic group-based treatment programme (PDT).

DESIGN

A naturalistic, longitudinal, comparison study.

METHODS

The sample included 345 patients with BPD (PDTn = 281, MBTn = 64). The number of diagnosed PDs, PD criteria, and symptom disorders were chosen as baseline indicators of clinical severity. Clinical outcomes (global functioning, symptom distress, interpersonal problems) were repeatedly assessed over three years. Therapists' fidelity to MBT was satisfactory. Linear mixed models were the applied statistics.

RESULTS

In PDT, greater clinical severity was associated with poorer improvement rates. Clinical severity was not associated with significant differences in outcomes for patients in MBT. Differences in outcomes for patients in MBT and PDT increased significantly with higher severity of disorder.

CONCLUSIONS

Supporting previous research, this study indicates that clinical benefits associated with MBT also apply for BPD patients with severe conditions. The results also suggest that increasing severity was a challenge in PDT.

PRACTITIONER POINTS

MBT may be particularly beneficial for severely disordered BPD patients Differences between MBT and PDT were less pronounced in moderately disordered BPD patients.

Avoidant personality disorder: current insights

Avoidant personality disorder (AVPD) is a relatively common disorder that is associated with significant distress, impairment, and disability. It is a chronic disorder with an early age at onset and a lifelong impact. Yet it is underrecognized and poorly studied. Little is known regarding the most effective treatment. The impetus for research into this condition has waxed and waned, possibly due to concerns regarding its distinctiveness from other disorders, especially social anxiety disorder (SAD), schizoid personality disorder, and dependent personality disorder. The prevailing paradigm subscribes to the "severity continuum hypothesis", in which AVPD is viewed essentially as a severe variant of SAD. However, areas of discontinuity have been described, and there is support for retaining AVPD as a distinct diagnostic category. Recent research has focused on the phenomenology of AVPD, factors of possible etiological significance such as early parenting experiences, attachment style, temperament, and cognitive processing. Self-concept, avoidant behavior, early attachments, and attachment style may represent points of difference from SAD that also have relevance to treatment. Additional areas of research not focused specifically on AVPD, including the literature on social cognition as it relates to attachment and personality style, report findings that are promising for future research aimed at better delineating AVPD and informing treatment.

Avoidant personality disorder and social phobia: Does mindreading make the difference?

OBJECTIVE

Avoidant personality disorder (AvPD) is closely related to and partially overlaps with social phobia (SP). There is an ongoing debate as to whether AvPD and SP can be classified as separate and distinct disorders or whether these diagnoses rather reflect different degrees of severity of social anxiety. The hypothesis of this study is that in patients with AvPD and in those with AvPD and comorbid SP both interpersonal functioning and metacognitive abilities (the ability to understand mental states) are more severely impaired than they are in patients with SP only. We also hypothesise that the interpersonal and metacognitive functioning of these patients (both AvPD and AvPD+SP) is comparable to that of patients with other PD diagnoses.

METHODS

To test this hypothesis, we compared four groups (22 patients with SP, 32 patients with AvPD, 43 patients with both AvPD and SP and 50 patients with other personality disorders without SP and AvPD criteria) on metacognitive abilities, interpersonal functioning and global symptomatic distress.

RESULTS

Metacognitive ability showed significant variation among the four groups, with the lowest score observed in the AvPD group. As far as the interpersonal functioning is concerned, the lack of sociability was more severe in the AvPD group compared with the SP group. These differences were maintained even after controlling for global symptomatic distress.

CONCLUSION

Results are in line with the alternative model of PD, proposed in the DSM-5, as dysfunction of the self and relationships. They suggest that specific impairments in critical areas of self domains and interpersonal domains of personality functioning may serve as markers distinguishing AvPD from SP.

Group schema therapy versus group cognitive behavioral therapy for social anxiety disorder with comorbid avoidant personality disorder: study protocol for a randomized controlled trial

BACKGROUND

Social anxiety disorder (SAD) with comorbid avoidant personality disorder (APD) has a high prevalence and is associated with serious psychosocial problems and high societal costs. When patients suffer from both SAD and APD, the Dutch multidisciplinary guidelines for personality disorders advise offering prolonged cognitive behavioral therapy (CBT). Recently there is increasing evidence for the effectiveness of schema therapy (ST) for personality disorders such as borderline personality disorder and cluster C personality disorders. Since ST addresses underlying personality characteristics and maladaptive coping strategies developed in childhood, this treatment might be particularly effective for patients with SAD and comorbid APD. To our knowledge, there are no studies comparing CBT with ST in this particular group of patients. This superiority trial aims at comparing the effectiveness of these treatments. As an additional goal, predictors and underlying mechanisms of change will be explored.

METHODS/DESIGN

The design of the study is a multicentre two-group randomized controlled trial (RCT) in which the treatment effect of group cognitive behavioral therapy (GCBT) will be compared to that of group schema therapy (GST) in a semi-open group format. A total of 128 patients aged 18-65 years old will be enrolled. Patients will receive 30 sessions of GCBT or GST during a period of approximately 9 months. Primary outcome measures are the Liebowitz Social Anxiety Scale Self-Report (LSAS-SR) for social anxiety disorder and the newly developed Avoidant Personality Disorder Severity Index (AVPDSI) for avoidant personality disorder. Secondary outcome measures are the MINI section SAD, the SCID-II section APD, the Schema Mode Inventory (SMI-2), the Inventory of Depressive Symptomatology Self-Report (IDS-SR), the World Health Organization Quality of Life-BREF (WHOQOL-BREF), the Difficulties in Emotion Regulation Scale (DERS), the Rosenberg Self-Esteem Scale (RSES) and the Acceptance and Action Questionnaire (AAQ-II). Data will be collected at the start, halfway and at the end of the treatment, followed by measurements at 3, 6 and 12 months post-treatment.

DISCUSSION

The trial will increase our knowledge on the effectiveness and applicability of both treatment modalities for patients suffering from both diagnoses.

Sex determines cortisol and alpha-amylase responses to acute physical and psychosocial stress in patients with avoidant personality disorder

INTRODUCTIONS

Avoidant personality disorder (AVPD) has excessive and pervasive anxiety and discomfort in social situations. The aims of this study were to explore the relationship between AVPD and physical and psychological stress and psychological tests.

METHODS

We evaluated 93 AVPD patients and 355 nonpatient controls by salivary amylase and cortisol responses during exposure to the Trier Social Stress Test (TSST) and electrical stimulation stress. Spielberger state-trait anxiety inventory (STAI), Profile of Mood State (POMS), Beck Depression Inventory (BDI), Depression and Anxiety Cognition Scale (DACS), and Childhood Trauma Questionnaire (CTQ) were administered.

RESULTS

Following electrical stimulation, salivary cortisol levels in female AVPD decreased significantly less than that in female's controls, but salivary cortisol levels did not show a difference between male AVPD patients and controls. Salivary alpha-amylase (sAA) levels did not show a difference between females or male AVPD patients and controls. Following TSST exposure, sAA levels did not show a difference between females or male AVPD patients and controls. Salivary cortisol levels did not show a difference between females or male AVPD patients and controls. In the AVPD patients, POMS scores were significantly higher compared with the controls. STAI, BDI, DACS scores, and CTQ significantly increased in the AVPD patients compared with the controls. LF in heart rate variability in AVPD significantly increased more compared with controls.

CONCLUSIONS

These results suggest that heightened sympathetic reactivity in female AVPD co-occurs with attenuated salivary cortisol responses to electric stimulation stress and there is a significant difference between AVPD and controls in mood, anxiety, social cognition, and automatic nerve systems.
