Defense style changes with the addition of psychodynamic group therapy to clonazepam in social anxiety disorder

Approximating defense mechanisms in a national study of adults: prevalence and correlates with functioning

Despite the clinical relevance of defense mechanisms, there are no published studies in nationally representative samples of their prevalence, correlates, and association with psychosocial functioning. We sought to estimate the prevalence and correlates of 12 defense mechanisms in the general adult population by approximating from items used to assess personality traits in the National Epidemiological Survey on Alcohol and Related Conditions (NESARC), a representative sample of US adults (N = 36,653). We examined the associations between sociodemographic characteristics and prevalence of 3 types of defenses mechanisms (pathological, immature, and neurotic). For each defense mechanism, we used the Short-Form 12 to compare psychosocial functioning among 3 groups: those who (1) endorsed the mechanism with self-recognized impairment, (2) endorsed the mechanism without self-recognized impairment, and (3) did not endorse the defense mechanism. The prevalence of defense mechanisms ranged from 13.2% (splitting) to 44.5% (obsessive/controlling behavior). Pathological defenses were more strongly associated with immature defenses (OR = 5.4, 95% CI = 5.2-5.6) than with neurotic defenses (OR = 2.0, 95% CI = 1.9-2.0), whereas the association between immature and neurotic defenses had an intermediate value between the other two (OR = 2.2, 95% CI = 2.1-2.2). Pathological and immature defenses were associated with younger age, having been never married, lower educational attainment, and lower income. After adjusting the crude results for age and sex, individuals who did not endorse a given defense generally had higher scores on the mental health component of the SF-12 than those who endorsed the defense without self-recognized impairment who, in turn, had on average higher scores than those with self-recognized impairment. These results suggest that neurotic, immature, and pathological defense mechanisms are prevalent in the general population and associated with psychosocial impairment. Recognizing defense mechanisms may be important in clinical practice regardless of treatment modality.

Increasing Mentalization to Reduce Maladaptive Defense in Patients With Mental Disorders

Background: There are indications of associations between the ability to mentalize and psychological defense mechanisms. However, only a few studies have focused on these associations, and even fewer have included empirical analyses. In the present study, we aimed to fill this research gap by analyzing the link between the ability to mentalize and psychological defense mechanisms in patients with mental disorders. We examined whether changes in defense mechanisms are predicted by an increase in mentalization or whether such changes are only related to reductions in psychopathology and interpersonal problems. Methods: A clinical sample of N = 89 patients was studied during and after inpatient psychiatric rehabilitation. Repeated-measures analyses of variance were performed to determine changes in mentalization, psychological defense, psychopathology, and interpersonal problems over the course of therapy and post-treatment. Linear regression analyses were used to predict the change in defense patterns based on an increase in mentalization. Results: Maladaptive defense mechanisms were significantly reduced during inpatient therapy and remained low until follow-up, whereas neurotic and adaptive defense mechanisms did not change significantly. The results of the regression analyses indicated that mentalization played an important role in the reduction in maladaptive defense during and after inpatient rehabilitation for mental disorders, whereas reductions in psychopathology and interpersonal distress were only partially associated with a reduction in maladaptive defense. Conclusion: We conclude that mentalization is vital for reducing maladaptive defense mechanisms, which are commonly associated with mental disorders. In therapy, an increase in patients' capacity to mentalize may be a practicable approach to diminish maladaptive defense mechanisms.

The effectiveness of art therapy for anxiety in adults: A systematic review of randomised and non-randomised controlled trials

Background

Anxiety disorders are one of the most diagnosed mental health disorders. Common treatment consists of cognitive behavioral therapy and pharmacotherapy. In clinical practice, also art therapy is additionally provided to patients with anxiety (disorders), among others because treatment as usual is not sufficiently effective for a large group of patients. There is no clarity on the effectiveness of art therapy (AT) on the reduction of anxiety symptoms in adults and there is no overview of the intervention characteristics and working mechanisms.

Methods

A systematic review of (non-)randomised controlled trials on AT for anxiety in adults to evaluate the effects on anxiety symptom severity and to explore intervention characteristics, benefitting populations and working mechanisms. Thirteen databases and two journals were searched for the period 1997 –October 2017. The study was registered at PROSPERO (CRD42017080733) and performed according to the Cochrane recommendations. PRISMA Guidelines were used for reporting.

Results

Only three publications out of 776 hits from the search fulfilled the inclusion criteria: three RCTs with 162 patients in total. All studies have a high risk of bias. Study populations were: students with PTSD symptoms, students with exam anxiety and prisoners with prelease anxiety. Visual art techniques varied: trauma-related mandala design, collage making, free painting, clay work, still life drawing and house-tree-person drawing. There is some evidence of effectiveness of AT for pre-exam anxiety in undergraduate students. AT is possibly effective in reducing pre-release anxiety in prisoners. The AT characteristics varied and narrative synthesis led to hypothesized working mechanisms of AT: induce relaxation; gain access to unconscious traumatic memories, thereby creating possibilities to investigate cognitions; and improve emotion regulation.

Conclusions

Effectiveness of AT on anxiety has hardly been studied, so no strong conclusions can be drawn. This emphasizes the need for high quality trials studying the effectiveness of AT on anxiety.

Towards an evidence-based unified psychodynamic protocol for emotional disorders

BACKGROUND

In psychotherapy research unified, transdiagnostic and modular treatments have emerged. This is true for both cognitive-behavioral therapy and psychodynamic therapy. Recently, two unified psychodynamic protocols were presented, one for anxiety disorders, another for depressive disorders. Integrating the treatment principles for these two highly prevalent disorder groups into one protocol for "emotional disorders" may be useful for both clinical practice and training in psychotherapy.

METHODS

After updating the evidence for psychodynamic therapy in anxiety and depressive disorders in terms of randomized controlled trials (RCTs) by a systematic search, the treatment elements applied in those RCTs providing evidence for the efficacy of psychodynamic therapy in depressive or anxiety disorders were reviewed and compared.

RESULTS

Twenty-seven RCTs for anxiety or depressive disorders were identified. A review revealed a high overlap between the principles used for the psychodynamic treatment of anxiety and depressive disorders, reflecting the transdiagnostic nature of psychodynamic therapy. The overlap suggested to integrate the identified treatment principles into one unified psychodynamic protocol for "emotional disorders" (UPP-EMO). As a result, seven treatment principles or modules were distilled which can be flexibly applied depending on the patient´s symptoms and needs. In addition, a separate module addresses diagnostic assessment. Across modules, a focus on resources has been included.

LIMITATIONS

Despite being based on RCTs, UPP-EMO has not yet been examined in an RCT - which is planned as a next step.

CONCLUSIONS

As psychodynamic therapy is transdiagnostic in origin focusing on core underlying processes of mental disorders, acceptability of UPP-EMO among psychodynamic psychotherapists is likely to be high.

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.
