Do Patient Characteristics Predict Outcome of Psychodynamic Psychotherapy for Social Anxiety Disorder?

Predictors of Symptom Reduction and Remission Among People with Anxiety: Secondary Analyses from a Randomized Controlled Trial

Despite the substantial disease burden of anxiety disorders, only limited or conflicting data on prognostic factors is available. Most studies include patients in the secondary healthcare sector thus, the generalizability of findings is limited. The present study examines predictors of symptom reduction and remission in patients with anxiety disorders in a primary care setting. 214 patients with anxiety disorders, recruited as part of the Collabri Flex trial, were included in secondary analyses. Data on potential predictors of anxiety symptoms at 6-month follow-up was collected at baseline, including patient characteristics related to demography, illness, comorbidity, functional level, life quality, and self-efficacy. The outcomes were symptom reduction and remission. Univariate and multivariate linear and logistic regression analyses were conducted to assess the associations between predictor variables and the outcome, and machine-learning methods were also applied. In multiple linear regression analysis, anxiety severity at baseline (β = -6.05, 95% CI = -7.54,-4.56, p < 0.001) and general psychological problems and symptoms of psychopathology (SCL-90-R score) (β = 2.19, 95% CI = 0.24,4.14, p = 0.028) were significantly associated with symptom change at 6 months. Moreover, self-efficacy was associated with the outcome, however no longer significant in the multiple regression model. In multiple logistic regression analysis, anxiety severity at baseline (OR = 0.54, 95% CI = -1.13,-0.12, p = 0.018) was significantly associated with remission at 6 months. There was no predictive performance of the machine-learning models. Our study contributes with information that could be valuable knowledge for managing anxiety disorders in primary care.

A Brief Self-Compassionate Letter-Writing Intervention for Individuals with High Shame

Objectives

Over the last decade, the mental health of undergraduate students has been of increasing concern and the prevalence of psychological disorders among this population has reached an unprecedented high. Compassion-based interventions have been used to treat shame and self-criticism, both of which are common experiences among undergraduate students and transdiagnostic vulnerability factors for an array of psychological disorders. This randomized controlled study examined the utility of a brief online self-compassionate letter-writing intervention for undergraduate students with high shame.

Method

Participants were 68 undergraduates who scored in the upper quartile on shame. Individuals were randomly assigned to a 16-day self-compassionate letter-writing intervention (n = 29) or a waitlist control group (n = 39). Participants completed baseline, post-assessment, and one-month follow-up measures.

Results

Participants who practiced self-compassionate letter writing evidenced medium-to-large reductions in global shame, external shame, self-criticism, and general anxiety at post-assessment, and gains were sustained at follow-up. Additionally, there were trend-level effects for increases in self-compassion and decreases in depression for those who participated in the intervention.

Conclusions

This study examined the efficacy of self-compassionate letter-writing as a stand-alone intervention for undergraduate students with high shame. This brief, easily accessible, and self-administered practice may be beneficial for a host of internalizing symptoms in this population and may support university counseling centers as they navigate high demand for mental health services.

Personality subtypes in adults with social anxiety disorder - novelty seeking makes the difference

BACKGROUND

Up to now several subtypes of social anxiety disorder (SAD) have been proposed.

METHODS

In the present study, we used a cluster analytic approach to identify qualitatively different subgroups of SAD based on temperament characteristics, that is, harm avoidance (HA) and novelty seeking (NS) dimensions of Cloninger's Temperament and Character Inventory.

RESULTS

Based on a large, diverse clinical sample (n = 575), we found evidence for two distinct subgroups of SAD: a larger (59%) prototypic, inhibited cluster characterized by high HA and low NS, and a smaller atypic, and comparatively more impulsive cluster characterized by medium to high HA and increased NS. The subgroups differed regarding a variety of sociodemographic and clinical variables. While the prototypic SAD subtype suffered from more severe SAD and depressive symptoms, suicidal ideation, and reduced social functioning, the atypic NS subtype showcased higher reproductive behaviour, self-directedness and -transcendence, comparatively. Additional hierarchical logistic regression highlights the contribution of age and education.

CONCLUSIONS

Our results valuably extend previous evidence for the existence of at least two distinct subtypes of SAD. A better knowledge of the characteristic differences in prototypic behaviour, personality, coping strategies and comorbidities between the identified (and further) subtypes can contribute to the development of effective prevention interventions and promotes the conceptualization of tailored treatments.

The efficacy of psychodynamic therapy for social anxiety disorder-A comprehensive meta-analysis

The efficacy of psychodynamic therapy (PDT) on social anxiety disorder (SAD) is controversial among different randomized controlled trials (RCTs), so we decide to conduct a comprehensive meta-analysis to study the efficacy of PDT on SAD. Relevant literatures were searched in PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, PsycINFO, Clinical Trails, and Ovid Medline. Twelve RCTs including 1,213 patients were identified. The primary analysis showed that the efficacy of PDT was weaker than the active group (SMD = 0.15 [0.02, 0.28]) and stronger than the inactive group (SMD = -0.77 [-0.95, -0.58]). It suggested that there was significant difference between individual PDT and group PDT (Chi² = 2.84, P = 0.09), and no difference between PDT and CBT on SAD and in the dropout rate. Secondary analysis suggested that depression may be alleviated concurrently (SMD = -0.20 [-0.40, 0.00]). Meta-regression analysis revealed no linear associations between dropout rate and effect size (t = 0.79, P = 0.449), neither does the dose-response relationship between session and effect size (t = -0.01, P = 0.992). These findings demonstrated that PDT could produce significant SAD symptoms reduction and supported its application in treating SAD.

Examining the relationship between shame and social anxiety disorder: A systematic review

This paper is the first systematic review of the literature on the relationship between shame and social anxiety (SA). We reviewed a total of 60 peer-reviewed empirical articles that met criteria for inclusion. We begin by summarizing literature investigating the empirical association between shame and SA and review literature on whether this association is impacted by cultural or diagnostic differences. Next, we briefly describe the updated version of Rapee and Heimberg's (1997) cognitive-behavioral model of social anxiety disorder (SAD; Heimberg, Brozovich, & Rapee, 2014) and propose how shame may interact with five processes described therein: environmental experiences, observations/images of the self, perceived negative evaluation by others, post-event cognitive processes, and behavioral manifestations of SA. We review the current literature on shame and SA as it relates to each of these domains. Thereafter, we discuss existing research on the role of shame in the treatment of SAD and the implications of the research discussed in this review. Finally, we conclude with a discussion of some key limitations in the existing literature and areas for future research.

Typical symptom change patterns and their predictors in patients with social anxiety disorder: A latent class analysis

OBJECTIVES

The use of trajectories and analysis of change patterns is a promising way toward better differentiation of subgroups in psychotherapy studies. Research on change patterns in social anxiety disorder (SAD) are still rare, although SAD is one of the most common mental disorders. In a secondary analysis of data from the SOPHO-NET-trial (ISRCTN53517394) this study aimed to investigate change patterns and their predictors in a sample of SAD patients.

METHODS

Patients with SAD (N = 357) were randomly assigned to cognitive-behavioral or psychodynamic therapy. The Liebowitz Social Anxiety Scale (LSAS) was assessed at 1^st session (pre), 8th session, 15th session and at the end of treatment (post). We used latent state variables and latent class analysis for the classification of change patterns and logistic regression for the identification of different predictors.

RESULTS

Analyses revealed three typical patterns: (i.) responders with a high initial impairment (N = 57), (ii.) responders with a moderate initial impairment (N = 225), and (iii.) patients with a high initial impairment and no remission (N = 75). Among other significant predicators, patient´s attachment anxiety and therapeutic alliance at session eight contributed to the prediction of change patterns.

DISCUSSION

Psychotherapy of SAD should consider patient's attachment and focus on the establishment of a solid therapeutic alliance in an early therapy stage.

Personalized prediction of smartphone-based psychotherapeutic micro-intervention success using machine learning

BACKGROUND

Tailoring healthcare to patients' individual needs is a central goal of precision medicine. Combining smartphone-based interventions with machine learning approaches may help attaining this goal. The aim of our study was to explore the predictability of the success of smartphone-based psychotherapeutic micro-interventions in eliciting mood changes using machine learning.

METHODS

Participants conducted daily smartphone-based psychotherapeutic micro-interventions, guided by short video clips, for 13 consecutive days. Participants chose one of four intervention techniques used in psychotherapeutic approaches. Mood changes were assessed using the Multidimensional Mood State Questionnaire. Micro-intervention success was predicted using random forest (RF) tree-based mixed-effects logistic regression models. Data from 27 participants were used, totaling 324 micro-interventions, randomly split 100 times into training and test samples, using within-subject and between-subject sampling.

RESULTS

Mood improved from pre- to post-intervention in 137 sessions (initial success-rate: 42.3%). The RF approach resulted in predictions of micro-intervention success significantly better than the initial success-rate within and between subjects (positive predictive value: 0.732 (95%-CI: 0.607; 0.820) and 0.698 (95%-CI: 0.564; 0.805), respectively). Prediction quality was highest using the RF approach within subjects (rand accuracy: 0.75 (95%-CI: 0.641; 0.840), Matthew's correlation coefficient: 0.483 (95%-CI: 0.323; 0.723)).

LIMITATIONS

The RF approach does not allow firm conclusions about the exact contribution of each factor to the algorithm's predictions. We included a limited number of predictors and did not compare whether predictability differed between psychotherapeutic techniques.

CONCLUSIONS

Our findings may pave the way for translation and encourage scrutinizing personalized prediction in the psychotherapeutic context to improve treatment efficacy.

Predicting treatment outcome for anxiety disorders with or without comorbid depression using clinical, imaging and (epi)genetic data

PURPOSE OF REVIEW

The present review complements previous reviews on prediction research in anxiety disorders with a focus on clinical, imaging and genetic as well as epigenetic factors and aims to provide recommendations for the design of future integrative studies in adults as well as children.

RECENT FINDINGS

Clinical factors predicting worse outcome such as a diagnosis of social anxiety disorder, comorbid depression and certain cognitive, behavioral and personality traits as well as low socioeconomic status were confirmed in large clinical studies. Imaging factors focusing on the fear and anxiety network were repeatedly described as predicting therapy response in small exploratory studies. The plethora of candidate gene studies has now been complemented by large genome-wide association studies and small epigenetic investigations with the need for replication in larger samples.

SUMMARY

The present status of research on predictors for therapy response in anxiety disorders, in particular on imaging and genetic factors, is still fragmentary. Some clinical factors for poorer outcome, though, have been consistently replicated and should be considered in the revision of therapy guidelines. There is a definite need for large integrative studies at the national and international level integrating multiple levels of biomarkers at different stages of development.

Psychodynamic day treatment programme for patients with schizophrenia spectrum disorders: Dynamics and predictors of therapeutic change

OBJECTIVES

The purpose of this study was to test whether a psychodynamically based group psychotherapeutic programme might improve symptoms, social functions, or quality of life in patients with schizophrenia spectrum disorders and to investigate factors that might predict clinical improvement or dropouts from the programme.

DESIGN

A quantitative prospective cohort study.

METHODS

We have investigated 81 patients with schizophrenia spectrum disorders who participated in a 9-month psychodynamically based psychotherapeutic day programme. The patients were assessed at the beginning and end of the programme, and then at 1-year follow-up. The assessment included psychotic manifestations (HoNOS), quality of life (WHOQOL-BREF), demographic data, and daily doses of medication. 21 patients dropped out from the programme, and 46 patients succeeded in undergoing follow-up assessment.

RESULTS

The psychotic manifestations (self-rating version of HoNOS) and quality of life measured with WHOQOL-BREF (domains of social relationships and environment) were significantly improved at the end of the programme and at follow-up. However, the manifestations on the version for external evaluators of HoNOS were improved only at follow-up. Years of psychiatric treatment, number of hospitalizations or suicide attempts, and experience of relationships with a partner were negatively related to clinical improvement, whereas symptom severity, current working, or study activities were related positively.

CONCLUSIONS

The results show that a group psychodynamic programme may improve the clinical status and quality of life of patients with schizophrenia spectrum disorders. This type of programme is more beneficial for patients with higher pre-treatment symptom severity and the presence of working or study activities.

PRACTITIONER POINTS

A psychodynamically based group programme improves the clinical status and quality of life in patients with schizophrenia spectrum disorders. Data indicate that changes on the subjective level are detectable by the end of the programme, while changes on the objective level are detectable at follow-up assessment. Symptom severity and working or study activities are positively related to the clinical improvement in this type of programme, while a high number of years in psychiatric treatment or psychiatric hospitalizations are negatively related. The doses of medication (antipsychotics or antidepressants) show no significant relationship to clinical improvement.

Changes of attachment characteristics during psychotherapy of patients with social anxiety disorder: Results from the SOPHO-Net trial

Objectives

Within a randomized controlled trial contrasting the outcome of manualized cognitive-behavioral (CBT) and short term psychodynamic therapy (PDT) compared to a waiting list condition (the SOPHO-Net trial), we set out to test whether self-reported attachment characteristics change during the treatments and if these changes differ between treatments.

Research design and methods

495 patients from the SOPHO-Net trial (54.5% female, mean age 35.2 years) who were randomized to either CBT, PDT or waiting list (WL) completed the partner-related revised Experiences in Close Relationships Questionnaire (ECR-R) before and after treatment and at 6 and 12 months follow-up. The Liebowitz Social Anxiety Scale (LSAS) was administered at pre-treatment, post-treatment, and at 6-month and 1-year follow-up. ECR-R scores were first compared to a representative healthy sample (n = 2508) in order to demonstrate that the clinical sample differed significantly from the non-clinical sample with respect to attachment anxiety and avoidance.

Results

LSAS scores correlated significantly with both ECR-R subscales. Post-therapy, patients treated with CBT revealed significant changes in attachment anxiety and avoidance whereas patients treated with PDT showed no significant changes. Changes between post-treatment and the two follow-ups were significant in both conditions, with minimal (insignificant) differences between treatments at the 12- month follow-up.

Conclusions

The current study supports recent reviews of mostly naturalistic studies indicating changes in attachment as a result of psychotherapy. Although there were differences between conditions at the end of treatment, these largely disappeared during the follow-up period which is line with the other results of the SOPHO-NET trial.

Anxiety Disorders and Temperament-an Update Review

PURPOSE OF REVIEW

The review focused on associations between temperament dimensions and clinical features in different anxiety disorders, likewise in obsessive-compulsive disorder in clinical samples of adults. A literature search was conducted in the Medline and PsycINFO databases covering the years 2010-2016. A systematic review and grading of the level of evidence for an association between temperament dimension scores and clinical features in each disorder were performed.

RECENT FINDINGS

Twenty papers reporting 18 different studies were included. Five of the papers focused on panic disorder (PD), five on social anxiety disorder (SAD), three on post-traumatic stress disorder (PTSD), one on generalized anxiety disorder (GAD), three on obsessive-compulsive disorder (OCD), and an additional three papers on several anxiety disorders. The review consolidates the finding that trait anxiety, especially as assessed by Cloninger's model or the five-factor model, is a phenomenon common to all anxiety disorders and OCD. More follow-up studies including large samples are needed to differentiate the dimensional profiles of trait anxiety in specific disorders.

Transfer of manualized Short Term Psychodynamic Psychotherapy (STPP) for social anxiety disorder into clinical practice: results from a cluster-randomised controlled trial

BACKGROUND

Despite growing evidence for manualized psychodynamic treatments, there is a lack of studies on their transfer to routine practice. This is the first study to examine the effects of an additional training in manualized Short Term Psychodynamic Psychotherapy (STPP) on the outcome in routine psychotherapy for social anxiety disorder (SAD). The study is an extension to a large RCT comparing STPP to Cognitive-Behavioral Therapy of SAD.

METHODS

The manualized treatment was designed for a time limited approach with 25 individual sessions of STPP over 6 months. Private practitioners were randomized to training in manualized STPP (mSTPP) vs. treatment as usual without a specific training (tauSTPP). A total of 109 patients were enrolled (105 started treatment; 75 completed at least 20 treatment sessions). Assessments were conducted pre-treatment, after 8 and 15 weeks, after 25 treatment sessions, at the end of treatment, 6 and 12 months after termination of treatment. Remission as primary outcome was defined by the Liebowitz-Social-Anxiety-Scale (LSAS) score ≤30. Secondary outcomes were response (at least 31% reduction in LSAS), treatment duration and number of sessions, changes in social anxiety (LSAS, SPAI), depression (BDI), clinical global impression (CGI), and quality of life (EQ-5D).

RESULTS

Remission rates of mSTPP (9%) resp. tauSTPP (16%) and also response rates of 33% resp. 28% were comparable between the two treatment approaches as well as treatment duration and number of sessions. Most of the within-group differences (baseline to 25 sessions) indicated moderate to large improvements in both treatments; within-group differences from baseline to 12 months follow-up (LSAS, SPAI, BDI, CGI) were large ranging from d = -0.605 to d = -2.937. Benefits of mSTPP were limited to single outcomes.

CONCLUSIONS

Findings are discussed with regard to implementation and dissemination of empirically validated treatments in psychodynamic training and practice. SAD patients with a high comorbidity of personality disorders and a long treatment history may need longer treatments.
