Comparison of brief dynamic and cognitive-behavioural therapies in avoidant personality disorder

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.

Does Researcher Allegiance Bias Outcomes in Psychotherapy Research? A Quasi-Experimental Secondary Analysis

Researchers who conduct studies comparing the efficacy of two treatments often find that their preferred treatment outperforms the comparison treatment. This finding has been labelled the allegiance association. Although this association is robust, it is unclear whether it reflects an allegiance bias on the part of the researchers or whether it is noncausal, with researchers being allied to the more effective treatments. This study applied a quasi-experimental method proposed by a previous study to 19 pairs of treatment comparison studies. Each member of a pair had used the same two psychotherapies to treat clients with the same disorder, but the researchers in each of the two studies had opposing allegiances. If the authors of one study in the pair concluded that their preferred treatment was superior and the authors of the other study concluded that their preferred treatment was superior or that the two treatments were equivalent, these patterns would suggest allegiance bias. In 10 of the 19 pairs, the patterns were consistent with the operation of an allegiance bias, indicating that although allegiance biases are not inevitable, they are ubiquitous. Practitioners and other psychotherapy research consumers should use caution when interpreting the findings from treatment comparison studies.

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.

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.

Individual psychotherapy for cluster-C personality disorders: protocol of a pragmatic RCT comparing short-term psychodynamic supportive psychotherapy, affect phobia therapy and schema therapy (I-FORCE)

BACKGROUND

Cluster-C personality disorders (PDs) are highly prevalent in clinical practice and are associated with unfavourable outcome and chronicity of all common mental health disorders (e.g. depression and anxiety disorders). Although several forms of individual psychotherapy are commonly offered in clinical practice for this population, evidence for differential effectiveness of different forms of psychotherapy is lacking. Also, very little is known about the underlying working mechanisms of these psychotherapies. Finding evidence on the differential (cost)-effectiveness for this group of patients and the working mechanisms of change is important to improve the quality of care for this vulnerable group of patients.

OBJECTIVE

In this study, we will compare the differential (cost)-effectiveness of three individual psychotherapies: short-term psychodynamic supportive psychotherapy (SPSP), affect phobia therapy (APT) and schema therapy (ST). Although these psychotherapies are commonly used in clinical practice, evidence for the Cluster-C PDs is limited. Additionally, we will investigate predictive factors, non-specific and therapy-specific mediators.

METHODS

This is a mono-centre randomized clinical trial with three parallel groups: (1) SPSP, (2) APT, (3) ST. Randomization on patient level will be pre-stratified according to type of PD. The total study population to be included consists of 264 patients with Cluster-C PDs or other specified PD with mainly Cluster-C traits, aged 18-65 years, seeking treatment at NPI, a Dutch mental health care institute specialized in PDs. SPSP, APT and ST (50 sessions per treatment) are offered twice a week in sessions of 50 min for the first 4 to 5 months. After that, session frequency decreases to once a week. All treatments have a maximum duration of 1 year. Change in the severity of the PD (ADP-IV) will be the primary outcome measure. Secondary outcome measures are personality functioning, psychiatric symptoms and quality of life. Several potential mediators, predictors and moderators of outcome are also assessed. The effectiveness study is complemented with a cost-effectiveness/utility study, using both clinical effects and quality-adjusted life-years, and primarily based on a societal approach. Assessments will take place at baseline, start of treatment and at 1, 3, 6, 9, 12, 18, 24 and 36 months.

DISCUSSION

This is the first study comparing psychodynamic treatment to schema therapy for Cluster-C PDs. The naturalistic design enhances the clinical validity of the outcome. A limitation is the lack of a control group for ethical reasons.

Effectiveness of outpatient and community treatments for people with a diagnosis of 'personality disorder': systematic review and meta-analysis

BACKGROUND

Quality of care and access to effective interventions have been widely criticised as limited for people diagnosed with 'personality disorder' or who have comparable needs (described in some recent papers as "Complex Emotional Needs" (CEN). It is important to identify effective interventions and the optimal context and mode of delivery for people with CEN. We aimed to investigate the effectiveness of psychosocial interventions delivered in community and outpatient settings in treating symptoms associated with 'personality disorder', and the moderating effects of treatment-related variables.

METHODS

We systematically searched MEDLINE, EMBASE, PsycINFO, CINAHL, HMIC, ASSIA for articles published in English, from inception to November 23, 2020. We included randomized controlled trials examining interventions provided in community or outpatient settings for CEN. The primary outcome was 'personality disorder' symptoms, while secondary outcomes included anxiety symptoms, depressive symptoms, and global psychiatric symptoms. Random-effects meta-analysis was conducted for each outcome, and meta-regression analysis was performed to assess the moderating effects of treatment characteristics. The quality of the studies and the degree of publication bias was assessed.

RESULTS

We included 54 trials (n = 3716 participants) in the meta-analysis. We found a large effect size (g = 0.78, 95% CI: 0.56 to 1.01, p < 0.0001) favoring interventions for 'borderline personality disorder' (BPD) symptoms over Treatment as Usual or Waitlist (TAU/WL), and the efficacy was maintained at follow-up (g = 1.01, 95% CI: 0.37 to 1.65, p = 0.002). Interventions effectively reduced anxiety symptoms (g = 0.58, 95% CI: 0.21 to 0.95, p = 0.002), depressive symptoms (g = 0.57, 95% CI: 0.32 to 0.83, p < 0.0001), and global psychiatric symptoms (g = 0.50, 95% CI: 0.35 to 0.66, p < 0.0001) compared to TAU/WL. The intervention types were equally effective in treating all symptom categories assessed. Treatment duration and treatment intensity did not moderate the effectiveness of the interventions for any outcome.

CONCLUSIONS

People with a 'personality disorder' diagnosis benefited from psychological and psychosocial interventions delivered in community or outpatient settings, with all therapeutic approaches showing similar effectiveness. Mental health services should provide people with CEN with specialised treatments in accordance with the availability and the patients' preferences.

Current state of the evidence on community treatments for people with complex emotional needs: a scoping review

BACKGROUND

Improving the quality of care in community settings for people with 'Complex Emotional Needs' (CEN-our preferred working term for services for people with a "personality disorder" diagnosis or comparable needs) is recognised internationally as a priority. Plans to improve care should be rooted as far as possible in evidence. We aimed to take stock of the current state of such evidence, and identify significant gaps through a scoping review of published investigations of outcomes of community-based psychosocial interventions designed for CEN.

METHODS

We conducted a scoping review with systematic searches. We searched six bibliographic databases, including forward and backward citation searching, and reference searching of relevant systematic reviews. We included studies using quantitative methods to test for effects on any clinical, social, and functioning outcomes from community-based interventions for people with CEN. The final search was conducted in November 2020.

RESULTS

We included 226 papers in all (210 studies). Little relevant literature was published before 2000. Since then, publications per year and sample sizes have gradually increased, but most studies are relatively small, including many pilot or uncontrolled studies. Most studies focus on symptom and self-harm outcomes of various forms of specialist psychotherapy: most result in outcomes better than from inactive controls and similar to other specialist psychotherapies. We found large evidence gaps. Adaptation and testing of therapies for significant groups (e.g. people with comorbid psychosis, bipolar disorder, post-traumatic stress disorder, or substance misuse; older and younger groups; parents) have for the most part only reached a feasibility testing stage. We found little evidence regarding interventions to improve social aspects of people's lives, peer support, or ways of designing effective services.

CONCLUSIONS

Compared with other longer term mental health problems that significantly impair functioning, the evidence base on how to provide high quality care for people with CEN is very limited. There is good evidence that people with CEN can be helped when specialist therapies are available and when they are able to engage with them. However, a much more methodologically robust and substantial literature addressing a much wider range of research questions is urgently needed to optimise treatment and support across this group.

Cluster B versus Cluster C Personality Disorders: A Comparison of Comorbidity, Suicidality, Traumatization and Global Functioning

A general clinical assumption states that cluster B personality disorders (PDs) represent a more severe form of PD than cluster C PDs. Consequently, most PD research is centered on cluster B PDs (especially borderline PD). Yet, prevalence ratings of cluster C PDs exceed those of cluster B PDs. In this explorative, cross-sectional study, we compared cluster B and C PD patients (N = 94) on a wide range of clinically-relevant severity measures, including comorbidity, suicidality, (childhood) traumatization and global functioning. Results showed that, although cluster B PD patients suffered more often from substance use disorders and lifetime suicide attempts, no difference could be established between groups for all other severity measures, including trauma variables. In our study, we additionally included a group of combined cluster B and C PDs, who were largely similar to both other groups. Although our study is insufficiently powered to claim a significant non-difference, these findings emphasize that high rates of comorbidity, suicidality, childhood traumatization and functional impairment apply to both cluster B and C patients. As such, our findings encourage more research into cluster C PDs, ultimately leading to more evidence-based treatments for this prevalent patient group. In addition, the high level of traumatization across groups calls for a routine trauma screening, especially since PD treatment may benefit from concurrent trauma treatment.

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.

[New insights into diagnostics and therapy of personality disorders-Changes in ICD-11]

Personality disorders (PD) occur frequently and show high remission rates in the long term, while psychosocial recovery remains unsuccessful in a substantial proportion of cases. In ICD-11 the traditional view that PDs have a high stability is abandoned. Instead, the minimum duration is 2 years. The diagnostic process differentiates between three degrees of severity (mild, moderate, severe) and five prominent personality trait domains. Optionally, a borderline qualifying factor can be additionally codified. There is sufficient empirical evidence only for the treatment of borderline PD (BPD). Disorder-specific psychotherapy, in particular dialectic behavioral therapy (DBT) and mentalization-based therapy (MBT) have proven to be effective. Therapy modules targeting functional impairments and prominent personality trait domains could close the existing gaps in the disorder-specific treatment of PD.

Long-term effects of transference interpretation in dynamic psychotherapy of personality disorders

Background

Only a few treatment studies of personality disorders (PD) patients are on longer-term psychotherapy, general outcome measures are used, and follow-up periods are usually short. More studies of long-term therapies, using outcome measures of core psychopathology, are needed.

Method

This study is a dismantling randomized controlled clinical trial, specifically designed to study long-term effects of transference interpretation. Forty-six patients with mainly cluster C personality disorders were randomly assigned to 1 year of dynamic psychotherapy with or without transference interpretations. The outcome measures were remission from PD, improvement in interpersonal functioning, and use of mental health resources in the 3-year period after treatment termination.

Results

After therapy with transference interpretation PD-patients improved significantly more in core psychopathology and interpersonal functioning, the drop-out rate was reduced to zero, and use of health services was reduced to 50%, compared to therapy without this ingredient. Three years after treatment termination, 73% no longer met diagnostic criteria for any PD in the transference group, compared to 44% in the comparison group.

Conclusions

PD-patients with co-morbid disorders improved in both treatment arms in this study. However, transference interpretation improved outcome substantially more. Long-term psychotherapy that includes transference interpretation is an effective treatment for cluster C personality disorders and milder cluster B personality disorders.

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.

Mandated Treatment and Its Impact on Therapeutic Process and Outcome Factors

Court-mandated treatments imply a dual role for therapy providers not only of caring for, but also of having control over, involuntary clients. The impact of legal coercion on the therapeutic relationship and feelings of stigma is widely regarded as negative and detrimental for treatment outcomes. This point of view stands in contrast to advocates of the perspective that involuntary treatment can ameliorate social functioning and thus promote a better quality of life. Regarding other outcome measures, there is evidence that offender treatment is effective and leads to reduced recidivism in criminal behavior. This narrative review provides an overview of research assessing the effects of mandatory treatment on therapeutic process and outcome factors. We conclude that legal mandatory treatment does not have to necessarily result in perceived coercion and reduced satisfaction with treatment and that a caring and authoritative treatment style aids a favorable therapeutic alliance, motivation, and therapy outcomes.

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.

Treatment of personality disorder: skills-based therapies

A variety of therapies have been developed or adapted to treat personality disorder over recent years. This article will review skills-based treatments (as opposed to insight-based treatments). Two approaches are outlined: cognitive-behavioural therapy and dialectical behaviour therapy. The article details the underpinning theory and the model of personality disorder utilised by the two approaches, and describes how the therapy is applied. Evidence of therapeutic efficacy is presented along with information about accessing training and therapy materials.

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.

Contemporary Cognitive Behavior Therapy: A Review of Theory, History, and Evidence

Cognitive behavior therapy (CBT) has come to be a widely practiced psychotherapy throughout the world. The present article reviews theory, history, and evidence for CBT. It is meant as an effort to summarize the forms and scope of CBT to date for the uninitiated. Elements of CBT such as cognitive therapy, behavior therapy, and so-called "third wave" CBT, such as dialectical behavior therapy (DBT) and acceptance and commitment therapy (ACT) are covered. The evidence for the efficacy of CBT for various disorders is reviewed, including depression, anxiety disorders, personality disorders, eating disorders, substance abuse, schizophrenia, chronic pain, insomnia, and child/adolescent disorders. The relative efficacy of medication and CBT, or their combination, is also briefly considered. Future directions for research and treatment development are proposed.

Frontiers in Cognitive Behaviour Therapy for Personality Disorders

Clinicians generally find individuals with personality disorders to be challenging to treat, especially compared to clients who have only a straightforward depression or anxiety disorder. In this article we will summarise research on the efficacy of cognitive behaviour therapy (CBT) for personality disorders. Then we will focus on the conceptualisation and treatment of CBT for personality disorders that is based on the work of Aaron Beck and colleagues; that is, it is predicated upon the cognitive model of psychopathology. Next, we will describe two other forms of treatment with cognitive behavioural roots: schema therapy and dialectical behaviour therapy. A final section will suggest future directions.

In cognitive therapy for depression, early focus on maladaptive beliefs may be especially efficacious for patients with personality disorders

OBJECTIVE

Patients with major depressive disorder (MDD) and a comorbid personality disorder (PD) have been found to exhibit relatively poor outcomes in cognitive therapy (CT) and other treatments. Adaptations of CT focusing heavily on patients' core beliefs have yielded promising findings in the treatment of PD. However, there have been no investigations that have specifically tested whether increased focus on maladaptive beliefs contributes to CT's efficacy for these patients.

METHOD

CT technique use from an early CT session was assessed for 59 patients (33 without PD, 26 with PD-predominantly Cluster C) who participated in a randomized controlled trial for moderate to severe MDD. Scores were calculated for directive CT techniques (CT-Concrete) and a set of belief-focused items (CT-Belief) as rated by the Collaborative Study Process Rating Scale. Robust regressions were conducted to estimate relations between scores on each of these measures and change in depressive and PD symptoms. A PD status by CT-Belief use interaction tested the hypothesis that therapist use of CT-Belief techniques would exhibit a stronger association with symptom change in the PD group relative to the non-PD group.

RESULTS

As hypothesized, a significant interaction between PD status and use of CT-Belief techniques emerged in the prediction of depressive and PD symptom change. Among PD patients, higher early CT-Belief interventions were found to predict significantly greater improvement. CT-Belief use did not predict greater symptom change among those without PD.

CONCLUSIONS

Early focus on CT-Belief interventions may facilitate changes in depression and PD symptoms for patients with MDD-PD comorbidity.

Avoidant Personality Disorder: a Current Review

This review focuses on recent research on diagnostic aspects, etiology, and treatment of avoidant personality disorder (AVPD). Current studies stress the close relation between AVPD and social anxiety disorder, the influence of genetic factors in the development of AVPD, and the relative stability of symptoms. Treatment approaches should target the pervasive patterns of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. Empirical evidence for cognitive-behavior and schema therapy is promising. Few other therapeutic approaches have been developed, but until now, these have only been investigated in case studies. We conclude that AVPD qualifies as a neglected disorder and that more research specifically on avoidant personality disorder symptoms and its treatment is needed.

The empirical status of psychodynamic psychotherapy - an update: Bambi's alive and kicking

BACKGROUND

The Task Force on Promotion and Dissemination of Psychological Procedures proposed rigorous criteria to define empirically supported psychotherapies. According to these criteria, 2 randomized controlled trials (RCTs) showing efficacy are required for a treatment to be designated as 'efficacious' and 1 RCT for a designation as 'possibly efficacious'. Applying these criteria modified by Chambless and Hollon, this article presents an update on the evidence for psychodynamic therapy (PDT) in specific mental disorders.

METHODS

A systematic search was performed using the criteria by Chambless and Hollon for study selection, as follows: (1) RCT of PDT in adults, (2) use of reliable and valid measures for diagnosis and outcome, (3) use of treatment manuals or manual-like guidelines, (4) adult population treated for specific problems and (5) PDT superior to no treatment, placebo or alternative treatment or equivalent to an established treatment.

RESULTS

A total of 39 RCTs were included. Following Chambless and Hollon, PDT can presently be designated as efficacious in major depressive disorder (MDD), social anxiety disorder, borderline and heterogeneous personality disorders, somatoform pain disorder, and anorexia nervosa. For MDD, this also applies to the combination with pharmacotherapy. PDT can be considered as possibly efficacious in dysthymia, complicated grief, panic disorder, generalized anxiety disorder, and substance abuse/dependence. Evidence is lacking for obsessive-compulsive, posttraumatic stress, bipolar and schizophrenia spectrum disorder(s).

CONCLUSIONS

Evidence has emerged that PDT is efficacious or possibly efficacious in a wide range of common mental disorders. Further research is required for those disorders for which sufficient evidence does not yet exist.

Psychodynamic therapy meets evidence-based medicine: a systematic review using updated criteria

Psychodynamic therapy (PDT) is an umbrella concept for treatments that operate on an interpretive-supportive continuum and is frequently used in clinical practice. The use of any form of psychotherapy should be supported by sufficient evidence. Efficacy research has been neglected in PDT for a long time. In this review, we describe methodological requirements for proofs of efficacy and summarise the evidence for use of PDT to treat mental health disorders. After specifying the requirements for superiority, non-inferiority, and equivalence trials, we did a systematic search using the following criteria: randomised controlled trial of PDT; use of treatment manuals or manual-like guidelines; use of reliable and valid measures for diagnosis and outcome; adults treated for specific mental problems. We identified 64 randomised controlled trials that provide evidence for the efficacy of PDT in common mental health disorders. Studies sufficiently powered to test for equivalence to established treatments did not find substantial differences in efficacy. These results were corroborated by several meta-analyses that suggest PDT is as efficacious as treatments established in efficacy. More randomised controlled trials are needed for some mental health disorders such as obsessive-compulsive disorder and post-traumatic stress disorder. Furthermore, more adequately powered equivalence trials are needed.

The effectiveness of psychodynamic psychotherapies: An update

This paper provides a comprehensive review of outcome studies and meta-analyses of effectiveness studies of psychodynamic therapy (PDT) for the major categories of mental disorders. Comparisons with inactive controls (waitlist, treatment as usual and placebo) generally but by no means invariably show PDT to be effective for depression, some anxiety disorders, eating disorders and somatic disorders. There is little evidence to support its implementation for post-traumatic stress disorder, obsessive-compulsive disorder, bulimia nervosa, cocaine dependence or psychosis. The strongest current evidence base supports relatively long-term psychodynamic treatment of some personality disorders, particularly borderline personality disorder. Comparisons with active treatments rarely identify PDT as superior to control interventions and studies are generally not appropriately designed to provide tests of statistical equivalence. Studies that demonstrate inferiority of PDT to alternatives exist, but are small in number and often questionable in design. Reviews of the field appear to be subject to allegiance effects. The present review recommends abandoning the inherently conservative strategy of comparing heterogeneous "families" of therapies for heterogeneous diagnostic groups. Instead, it advocates using the opportunities provided by bioscience and computational psychiatry to creatively explore and assess the value of protocol-directed combinations of specific treatment components to address the key problems of individual patients.

An Integrative Approach Using Third-Generation Cognitive-Behavioral Therapies for Avoidant Personality Disorder

Evidence-based practice emphasizes the integration of empirically supported treatments with clinical expertise and unique client characteristics. The present study describes an integrative approach using Acceptance and Commitment Therapy (ACT) and skills training adapted from Dialectical Behavior Therapy (DBT) to treat a client with avoidant personality disorder (AvPD), comorbid adjustment disorder, and self-injurious behavior. The process of matching the therapies to the client and specific techniques to symptoms and problem behaviors is described. Ongoing clinical measures indicated reductions in depression, hopelessness, and anxiety. Behavioral measures indicated remission of cutting behavior and increases in social and physical activities. Results from a 1-month follow-up suggested maintenance of gains and continued reduction in symptoms. The Minnesota Multiphasic Personality Inventory–2 (MMPI-2) profile at follow-up as compared with pre-treatment indicated significant decreases in the client’s experience and perception of her symptoms. Endorsements on the Acceptance and Action Questionnaire–II (AAQ-II) at mid-treatment and follow-up suggested that the client achieved greater psychological flexibility. This case serves as evidence that individuals with AvPD and significant symptoms of anxiety and depression can be receptive to, and can benefit from, the integration of third-generation cognitive-behavioral therapies.

Treatment of personality disorder

The evidence base for the effective treatment of personality disorders is insufficient. Most of the existing evidence on personality disorder is for the treatment of borderline personality disorder, but even this is limited by the small sample sizes and short follow-up in clinical trials, the wide range of core outcome measures used by studies, and poor control of coexisting psychopathology. Psychological or psychosocial intervention is recommended as the primary treatment for borderline personality disorder and pharmacotherapy is only advised as an adjunctive treatment. The amount of research about the underlying, abnormal, psychological or biological processes leading to the manifestation of a disordered personality is increasing, which could lead to more effective interventions. The synergistic or antagonistic interaction of psychotherapies and drugs for treating personality disorder should be studied in conjunction with their mechanisms of change throughout the development of each.

Short-term psychodynamic psychotherapies for common mental disorders

BACKGROUND

Since the mid-1970s, short-term psychodynamic psychotherapies (STPP) for a broad range of psychological and somatic disorders have been developed and studied. Early published meta-analyses of STPP, using different methods and samples, have yielded conflicting results, although some meta-analyses have consistently supported an empirical basis for STPP. This is an update of a review that was last updated in 2006.

OBJECTIVES

To evaluate the efficacy of STPP for adults with common mental disorders compared with wait-list controls, treatments as usual and minimal contact controls in randomised controlled trials (RCTs). To specify the differential effects of STPP for people with different disorders (e.g. depressive disorders, anxiety disorders, somatoform disorders, mixed disorders and personality disorder) and treatment characteristics (e.g. manualised versus non-manualised therapies).

SEARCH METHODS

The Cochrane Depression, Anxiety and Neurosis Group's Specialised Register (CCDANCTR) was searched to February 2014, this register includes relevant randomised controlled trials from The Cochrane Library (all years), EMBASE (1974-), MEDLINE (1950-) and PsycINFO (1967-). We also conducted searches on CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, DARE and Biological Abstracts (all years to July 2012) and all relevant studies (identified to 2012) were fully incorporated in this review update. We checked references from papers retrieved. We contacted a large group of psychodynamic researchers in an attempt to find new studies.

SELECTION CRITERIA

We included all RCTs of adults with common mental disorders, in which a brief psychodynamic therapy lasting 40 or fewer hours in total was provided in individual format.

DATA COLLECTION AND ANALYSIS

Eight review authors working in pairs evaluated studies. We selected studies only if pairs of review authors agreed that the studies met inclusion criteria. We consulted a third review author if two review authors could not reach consensus. Two review authors collected data and entered it into Review Manager software. Two review authors assessed and scored risk of bias. We assessed publication bias using a funnel plot. Two review authors conducted and reviewed subgroup analyses.

MAIN RESULTS

We included 33 studies of STPP involving 2173 randomised participants with common mental disorders. Studies were of diverse conditions in which problems with emotional regulation were purported to play a causative role albeit through a range of symptom presentations. These studies evaluated STPP for this review's primary outcomes (general, somatic, anxiety and depressive symptom reduction), as well as interpersonal problems and social adjustment. Except for somatic measures in the short-term, all outcome categories suggested significantly greater improvement in the treatment versus the control groups in the short-term and medium-term. Effect sizes increased in long-term follow-up, but some of these effects did not reach statistical significance. A relatively small number of studies (N < 20) contributed data for the outcome categories. There was also significant heterogeneity between studies in most categories, possibly due to observed differences between manualised versus non-manualised treatments, short versus longer treatments, studies with observer-rated versus self report outcomes, and studies employing different treatment models.

AUTHORS' CONCLUSIONS

There has been further study of STPP and it continues to show promise, with modest to large gains for a wide variety of people. However, given the limited data, loss of significance in some measures at long-term follow-up and heterogeneity between studies, these findings should be interpreted with caution. Furthermore, variability in treatment delivery and treatment quality may limit the reliability of estimates of effect for STPP. Larger studies of higher quality and with specific diagnoses are warranted.

A meta-analytic review of psychodynamic therapies for anxiety disorders

Recent randomized controlled trials (RCTs) suggest that psychodynamic therapy (PDT) may be useful in the treatment of anxiety disorders. This paper presents the most comprehensive meta-analysis to date examining the controlled effects of PDT for anxiety disorders. 14 RCTs totaling 1073 patients were included. PDT was found to be significantly more effective than control conditions (g=0.64). PDT did not differ significantly from alternative treatments at post-treatment (g=0.02), follow-up (FU) up to a year (g=-0.11), and FU past a year (g=-0.26). Medium-to-high levels of heterogeneity were detected, indicating significant differences between studies. Nevertheless, our findings remained unchanged when heterogeneity outliers were removed (termination g=-0.06/short FU g=-0.01/long FU g=-0.10). Power analyses indicated that large or medium effect size differences between PDT and other active treatments could be detected even with high heterogeneity. Exploratory moderator analyses found few significant predictors of effect (e.g., relative risk of dropout). No differences were found examining remission rates or relative risk of dropout. Overall, PDT was shown to be as efficacious as other active treatments that have been studied for anxiety disorders.

Cognitive analytic therapy for personality disorder: randomised controlled trial

BACKGROUND

Cognitive analytic therapy (CAT) is a theoretically coherent approach developed to address common processes underlying personality disorders, but is supported by limited empirical evidence.

AIMS

To investigate the effectiveness of time-limited CAT for participants with personality disorder.

METHOD

A service-based randomised controlled trial (trial registration: ISRCTN79596618) comparing 24 sessions of CAT (n = 38) and treatment as usual (TAU) (n = 40) over 10 months for individuals with personality disorder. Primary outcomes were measures of psychological symptoms and interpersonal difficulties.

RESULTS

Participants receiving CAT showed reduced symptoms and experienced substantial benefits compared with TAU controls, who showed signs of deterioration during the treatment period.

CONCLUSIONS

Cognitive analytic therapy is more effective than TAU in improving outcomes associated with personality disorder. More elaborate and controlled evaluations of CAT are needed in the future.

Interpersonal Psychotherapy Informed Treatment for Avoidant Personality Disorder With Subsequent Depression

This is a single-case study of a young woman with avoidant personality disorder (APD) and subsequent depression, worry, lack of motivation, feelings of inadequacy, and nonassertive behaviors in her romantic relationship and professional career. Treatment was informed by interpersonal psychotherapy (IPT) for depression and also utilized assertiveness skills training. The client’s self-confidence was tracked daily, using a subjective self-report measure, and the completion of personality and symptom assessment measures before treatment (Phase A) and during the termination stage of treatment. Simulation Modeling Analysis for Time Series evaluated the change in levels of self-confidence across baseline, active treatment (Phase B), and termination (Phase C). In addition, reliable change was assessed using a comparison of Minnesota Multiphasic Personality Inventory 2–Restructured Form and Symptom Checklist-90–Revised results from baseline and Phase C. The patient experienced symptom improvement in self-confidence, somatic complaints, stress and worry, anxiety, and depression, suggesting that IPT techniques may be useful in the treatment of APD.

Comorbidity of borderline personality disorder with other personality disorders in psychiatric outpatients: how does it look at 2-year follow-up?

BACKGROUND

The rates of remission of comorbid personality disorders for patients with a primary borderline personality disorder (BPD) have previously only been addressed in samples of inpatients or former inpatients with BPD receiving treatment-as-usual.

AIMS

The aim of the current study was to assess the rates of remission of comorbid axis II personality disorders in a sample of 32 outpatients with a primary BPD receiving open-ended non-manualized psychotherapy.

METHODS

Structured psychiatric interviews for DSM-IV were conducted by independent assessors at intake, discharge and 2-year follow-up. Independent t-test, chi-square and McNemar analyses based on intent-to-treat were used.

RESULTS

The overall rate of comorbid axis II disorders was significantly reduced from intake to 2-year follow-up. Patients with non-remitted BPD had significantly more PD diagnoses and symptomatic distress on all outcome measures at follow-up.

CONCLUSION

Comorbid personality disorders among outpatients with BPD can be expected to remit with time and with remission of BPD. In the current sample of outpatients, comorbid paranoid, avoidant and obsessive-compulsive personality disorders at 2-year follow-up were associated with non-remitted BPD. The clinical implication of the results is that especially comorbid avoidant and obsessive-compulsive personality disorders may require specific attention in treatment of patients with BPD.
