Enriching Cognitive Behavior Therapy with Emotion Regulation Training for Patients with Multiple Medically Unexplained Symptoms (ENCERT): Design and implementation of a multicenter, randomized, active-controlled trial

Addressing psychosocial needs in patients with Long-COVID (PsyLoCo-Study): study protocol of a pilot-study of a specialized modular intervention

Introduction

After an acute infection with the corona virus 10-20% of those affected suffer from ongoing or new symptoms. A causal therapy for the phenomenon known as Long/Post-COVID is still lacking and specific therapies addressing psychosocial needs of these patients are imperatively needed. The aim of the PsyLoCo-study is developing and piloting a psychotherapeutic manual, which addresses Long/Post-COVID-related psychosocial needs and supports in coping with persistent bodily symptoms as well as depressive or anxiety symptoms.

Methods and analysis

This pilot trial implements a multi-centre, 2-arm (N=120; allocation ratio: 1:1), parallel group, randomised controlled design. The pilot trial is designed to test the feasibility and estimate the effect of 1) a 12-session psychotherapeutic intervention compared to 2) a wait-list control condition on psychosocial needs as well as bodily and affective symptoms in patients suffering from Long/Post-COVID. The intervention uses an integrative, manualized, psychotherapeutic approach. The primary study outcome is health-related quality of life. Outcome variables will be assessed at three timepoints, pre-intervention (t1), post-intervention (t2) and three months after completed intervention (t3). To determine the primary outcome, changes from t1 to t2 are examined. The analysis will be used for the planning of the RCT to test the efficacy of the developed intervention.

Discussion

The pilot study will evaluate a 12-session treatment manual for Long/Post-COVID sufferers and the therapy components it contains. The analysis will provide insights into the extent to which psychotherapeutic treatment approaches improve the symptoms of Long/Post-COVID sufferers. The treatment manual is designed to be carried out by psychotherapists as well as people with basic training in psychotherapeutic techniques. This approach was chosen to enable a larger number of practitioners to provide therapeutic support for Long/Post-COVID patients. After completion of the pilot study, it is planned to follow up with a randomized controlled study and to develop a treatment guideline for general practitioners and interested specialists.

Trial registration

The pilot trial has been registered with the German Clinical Trials Register (Deutsches Register Klinischer Studien; Trial-ID: DRKS00030866; URL: https://drks.de/search/de/trial/DRKS00030866) on March 7, 2023.

[Nociplastic pain in research and practice : Overview of biopsychosocial principles, possibilities and difficulties]

Traditionally, two mechanistic pain categories were distinguished: nociceptive and neuropathic pain. After the definitions of these two mechanistic descriptors were refined more precisely in the International Association for the Study of Pain (IASP) taxonomy in 2011, a large group of patients remained whose pain could not be assigned to either of the two categories. Nociplastic pain was therefore proposed as a third mechanistic descriptor in 2016. This review article presents the current state of the integration of nociplastic pain into research and clinical practice. In particular, the possibilities and difficulties of applying this concept are addressed from a human and animal experimental research perspective.

The framework for systematic reviews on psychological risk factors for persistent somatic symptoms and related syndromes and disorders (PSY-PSS)

Introduction

Numerous psychological factors are believed to play a pivotal role in the development and maintenance of persistent somatic symptoms (PSS) in all fields of medicine. However, very few of these factors have been empirically investigated in relation to PSS. The aim of this study is firstly to propose a framework and define search terms for systematic reviews on the empirical evidence and diagnostic value of psychological risk factors for PSS and PSS-related outcomes (PSY-PSS). Secondly, the application of the framework is illustrated using the example of a systematic review on the relevance of psychological factors in somatic symptom disorders (SSD; DSM-5) and bodily distress disorders (BDD; ICD-11).

Methods

Following a narrative review approach, two comprehensive lists of search terms to identify studies in (1) relevant patient groups with PSS and (2) relevant psychological factors were generated by reviewing the current literature and employing an iterative process of internal revision and external expert feedback.

Results

We identified 83 relevant symptoms, syndromes and disorders for which we defined a total of 322 search terms (list 1). We further comprised 120 psychological factors into 42 subcategories and 7 main categories (list 2). The introduced lists can be combined to conduct systematic reviews on one or more specific psychological factors in combination with any symptom, syndrome or disorder of interest. A protocol of the application of this framework in a systematic review and meta-analysis on psychological etiological factors of SSD and BDD is presented following the PRISMA guidelines.

Discussion

This framework will help to gather systematic evidence on psychological factors in order to improve the understanding of the etiology of PSS, to refine future diagnostic conceptualizations of PPS, and to develop optimized mechanism-based interventions for individuals with PPS and related syndromes and disorders.

Network Analysis of Persistent Somatic Symptoms in Two Clinical Patient Samples

OBJECTIVE

Previous attempts to group persistent somatic symptoms (PSSs) with factor-analytic approaches have obtained heterogeneous results. An alternative approach that seems to be more suitable is the network theory. Compared with factor analysis, which focuses on the underlying factor of symptoms, network analysis focuses on the dynamic relationships and interactions among different symptoms. The main aim of this study is to apply the network approach to examine the heterogeneous structure of PSS within two clinical samples.

METHODS

The first data set consisted of n = 254 outpatients who were part of a multicenter study. The second data set included n = 574 inpatients, both with somatoform disorders. Somatic symptom severity was assessed with the Screening of Somatoform Disorder (SOMS-7T).

RESULTS

Results indicate that there are five main symptom groups that were found in both samples: neurological, gastrointestinal, urogenital, cardiovascular, and musculoskeletal symptoms. Although patterns of symptoms with high connection to each other look quite similar in both networks, the order of the most central symptoms (e.g., symptoms with a high connection to other symptoms in the network) differs.

CONCLUSIONS

This work is the first to estimate the structure of PSS using network analysis. A next step could be first to replicate our findings before translating them into clinical practice. Second, results may be useful for generating hypotheses to be tested in future studies, and the results open new opportunities for a better understanding for etiology, prevention, and intervention research.

Symptom change trajectories in patients with persistent somatic symptoms and their association to long-term treatment outcome

OBJECTIVE

This study investigated symptom change trajectory for patients with persistent somatic symptoms (PSS) during psychotherapy and the association of these patterns with pre-treatment characteristics and long-term outcome.

METHODS

Growth mixture modeling was used to identify trajectory curves in a sample of N = 210 outpatients diagnosed with PSS and treated either with conventional cognitive behavioral therapy (CBT) or CBT enriched with emotion regulation training (ENCERT).

RESULTS

We identified three subgroups of patients with similar symptom change patterns over the course of treatment (a "no change," "strong response," and "slow change" subgroup). Higher initial anxiety symptoms were significantly associated with the no change and strong response subgroups; symptom-related disability in daily routine with no changes. Patients with a strong response had the highest proportion of reliable improvement at termination and at six-month-follow-up.

CONCLUSION

Our results indicate that, instead of one common change pattern, patients with PSS respond differently to treatment. Due to the high association of symptom curves with long-term outcome, the identification and prediction of an individual's trajectory could provide important information for clinicians to identify non-responding patients that are at risk for failure. Selecting personalized treatment interventions could increase the effectiveness of psychotherapy.Trial registration: ClinicalTrials.gov identifier: NCT01908855..

Predicting optimal treatment outcomes using the Personalized Advantage Index for patients with persistent somatic symptoms

Because individual patients with persistent somatic symptoms (PSS) respond differently to treatments, a better understanding of the factors that predict therapy outcomes are of high importance. Aggregating a wide selection of information into the treatment-decision process is a challenge for clinicians. Using the Personalized Advantage Index (PAI) this study aims to deal with this. Methods: Data from a multicentre RCT comparing CBT (N = 128) versus CBT enriched with emotion regulation training (ENCERT) (N = 126) for patients diagnosed with somatic symptom disorder were used to identify based on two machine learning approaches predictors of therapy outcomes. The identified predictors were used to calculate the PAI. Results: Five treatment unspecific predictors (pre-treatment somatic symptom severity, depression, symptom disability, health-related quality of life, age) and five treatment specific moderators (global functioning, early childhood traumatic events, gender, health anxiety, emotion regulation skills) were identified. Individuals assigned to their PAI-indicated optimal treatment had significantly lower somatic symptom severity at the end of therapy compared to those randomised to their non-optimal condition. Conclusion: Allowing patients to choose a personalised treatment seems to be meaningful. This could help to improve outcomes for PSS and reduce its high costs to the health care system.

Psychotherapists' perspective on the treatment of patients with somatic symptom disorders

OBJECTIVE

Guidelines recommend psychotherapy in addition to primary care for patients with moderate to severe somatic symptom disorders. While general practitioners' experiences have been well studied, psychotherapists' experiences with this patient group and the explanatory models psychotherapists use in psychotherapy are unknown.

METHODS

Semi-structured qualitative interviews were conducted between April and July 2018 with 20 German licensed outpatient psychotherapists with either a medical or a psychological background, using the label "somatoform disorders". Interviews were analyzed applying thematic analysis.

RESULTS

Psychotherapists experienced management of affected patients as challenging and partly frustrating, mainly due to the difficult diagnostic process and the "somatic fixation" of some patients. Diagnostic labelling was considered a delicate issue, with some psychotherapists using the term "somatoform", while others preferred either "functional" or vague descriptions like "psychosomatic". The explanatory process was deemed essential for treatment, as was the adaptation of explanations to both a patient's biography and language. As main explanatory factors, psychotherapists referred to generic vulnerability factors, previous somatic illness and health care system influences.

CONCLUSIONS

Explanatory models used in psychotherapy are patient-centred, processual and constitute a major component of the psychotherapeutic process. However, this process might be impeded if patients are confronted with different diagnostic labels and explanatory models during their pathways through care.

Cognitive Behaviour Therapy Complemented with Emotion Regulation Training for Patients with Persistent Physical Symptoms: A Randomised Clinical Trial

INTRODUCTION

Persistent medically unexplained symptoms (MUS) are a major burden for health care. Cognitive behaviour therapy (CBT) is efficacious for patients with MUS, with small to medium effects. The current study investigates whether therapy outcomes of a CBT for MUS patients can be improved by complementing it with emotion regulation training.

METHODS

In a multicentre trial 255 patients with at least three persisting MUS were randomised to 20 sessions of either conventional CBT (n = 128) or CBT complemented with emotion regulation training (ENCERT; n = 127). Somatic symptom severity and secondary outcomes were assessed at pre-treatment, therapy session 8, end of therapy, and 6-month follow-up.

RESULTS

Linear mixed-effect models revealed medium to large effects in both study arms for almost all outcomes at the end of therapy and 6-month follow-up. ENCERT and CBT did not differ in their effect on the primary outcome (d = 0.20, 95% CI: -0.04 to 0.44). Significant time × group cross-level interactions suggested ENCERT to be of more benefit than conventional CBT for a few secondary outcomes. Moderator analyses revealed higher effects of ENCERT in patients with co-morbid mental disorders.

DISCUSSION/CONCLUSIONS

Current findings are based on a representative sample. Results demonstrate that both CBT and ENCERT can achieve strong effects on primary and secondary outcomes in MUS patients. Our results do not indicate that adding a training in emotion regulation skills generally improves the effect of CBT across all patients with MUS. Large effect sizes of both treatments and potential specific benefits of ENCERT for patients with co-morbid mental disorders are discussed.

Health anxiety, cyberchondria, and coping in the current COVID-19 pandemic: Which factors are related to coronavirus anxiety?

According to cognitive-behavioral models, traits, triggering events, cognitions, and adverse behaviors play a pivotal role in the development and maintenance of health anxiety. During virus outbreaks, anxiety is widespread. However, the role of trait health anxiety, cyberchondria, and coping in the context of virus anxiety during the current COVID-19 pandemic has not yet been studied. An online survey was conducted in the German general population (N = 1615, 79.8 % female, Mage = 33.36 years, SD = 13.18) in mid-March 2020, which included questionnaires on anxiety associated with SARS-CoV-2, trait health anxiety, cyberchondriaPandemic (i.e. excessive online information search), and emotion regulation. The participants reported a significantly increasing virus anxiety in recent months (previous months recorded retrospectively), especially among individuals with heightened trait health anxiety. CyberchondriaPandemic showed positive correlations with current virus anxiety (r = .09-.48), and this relationship was additionally moderated by trait health anxiety. A negative correlation was found between the perception of being informed about the pandemic and the current virus anxiety (r=-.18), with adaptive emotion regulation being a significant moderator for this relationship. The findings suggest that trait health anxiety and cyberchondria serve as risk factors, whereas information about the pandemic and adaptive emotion regulation might represent buffering factors for anxiety during a virus pandemic.

Affect regulation training reduces symptom severity in depression - A randomized controlled trial

Deficits in general emotion regulation skills have been shown to be associated with various mental disorders. Thus, general affect-regulation training has been proposed as promising transdiagnostic approach to the treatment of psychopathology. In the present study, we aimed to evaluate the efficacy of a general affect-regulation as a stand-alone, group-based treatment for depression. For this purpose, we randomly assigned 218 individuals who met criteria for major depressive disorder (MDD) to the Affect Regulation Training (ART), to a waitlist control condition (WLC), or to a condition controlling for common factors (CFC). The primary outcome was the course of depressive symptom severity as assessed with the Hamilton Rating Scale for Depression and the Beck Depression Inventory. Multi-level analyses indicated that participation in ART was associated with a greater reduction of depressive symptom severity than was participation in WLC (d = 0.56), whereas the slight superiority of ART over CFC (d = 0.25) was not statistically significant. Mediation analyses indicated that changes in emotion regulation skills mediated the differences between ART/CFC and WLC. Thus, the findings provide evidence for enhancing emotion regulation skills as a common mechanism of change in psychological treatments for depression. The study was registered with ClinicalTrials.gov (NCT01330485) and was supported by grants from the German Research Association (DFG; BE 4510/3-1; HI 456/6-2). Future research should compare the (cost-) efficacy of ART with that of disorder-specific interventions.

Emotion regulation in patients with somatic symptom and related disorders: A systematic review

Background

Somatic symptoms and related disorders (SSD) are prevalent phenomena in the health-care system. Disturbances in emotion regulation (ER) are commonly observed in patients suffering from SSD.

Objectives

This review aimed to examine ER processes that characterize SSD by a systematic analysis of the available empirical studies.

Data sources

PsycINFO and PubMed databases for the articles published between January 1985 and June 2018.

Search terms

“emotion/al regulation” or “affect regulation” and various forms of SSD.

Study eligibility criteria

Empirical studies that a) assigned adolescent or adult patients suffering from SSD based on a clinical diagnosis, and b) examined the relationship between ER and SSD, were included.

Study synthesis methods

A tabular summary of the articles was generated according to study characteristics, study quality, variables, and findings. The findings were organized based on ER variables used in the articles and diagnoses of SSD, which were then re-organized under the main constituents of ER (attention, body, and knowledge).

Results

The findings of the 64 articles largely supported the association between SSD and disturbances in ER, which are usually shared by different diagnoses of SSD. The results indicate that patients show a reduced engagement with cognitive content of emotions. On the other hand, bodily constituents of ER seem to depict an over-reactive pattern. Similarly, the patients tend to encounter difficulties in flexibly disengaging their (spontaneous) attention from emotional material.

Limitations

There is a scarcity of longitudinal designs, randomized controlled trials, experiments, and diary studies suited to investigate the short- and long-term causal relationship between ER and SSD. Symptoms of SSD and measures to assess emotion regulation are heterogeneous.

Conclusions and implications

Assessment of ER processes is potentially useful to understand SSD and for treatment planning. Furthermore, a concurrent investigation of the dynamic interaction of the ER modalities promises insights for better understanding of the role of ER in development, course, and maintenance of SSD.

[Tinnitus: psychosomatic aspects]

Tinnitus is a common symptom of unclear origin that can be multifactorially caused and maintained. It is frequently, but not inevitably, associated with hearing loss. Emotional distress and maladaptive coping strategies - that are associated with or amplified by the tinnitus percept - pose key targets for psychological interventions. Once somatic contributors are identified and treated as applicable, psychological approaches comprise normalizing psychoeducational and psychotherapeutic interventions. Measures to improve hearing perception (e. g., hearing aids or cochlear implants) can also contribute to tinnitus habituation through direct (improvement of hearing perception) or indirect (improvement of emotional wellbeing or quality of life) effects.

Management of somatic symptom disorder

This review paper gives an overview of the management of somatic symptom disorder. It starts with a description of the clinical problem of patients with persistent bodily distress, discusses classificatory, epidemiological, and etiological issues and then describes the evidence and practical principles of dealing with these patients who are often seen as "difficult" to treat. It is concluded that the best-suited approach is stepped care with close cooperation of primary care, a somatic specialist, and mental health care professionals operating on the basis of a biopsychosocial model of integrating somatic as well as psychosocial determinants of distress and therapeutic factors.

Management of Functional Somatic Syndromes and Bodily Distress

Functional somatic syndromes (FSS), like irritable bowel syndrome or fibromyalgia and other symptoms reflecting bodily distress, are common in practically all areas of medicine worldwide. Diagnostic and therapeutic approaches to these symptoms and syndromes vary substantially across and within medical specialties from biomedicine to psychiatry. Patients may become frustrated with the lack of effective treatment, doctors may experience these disorders as difficult to treat, and this type of health problem forms an important component of the global burden of disease. This review intends to develop a unifying perspective on the understanding and management of FSS and bodily distress. Firstly, we present the clinical problem and review current concepts for classification. Secondly, we propose an integrated etiological model which encompasses a wide range of biopsychosocial vulnerability and triggering factors and considers consecutive aggravating and maintaining factors. Thirdly, we systematically scrutinize the current evidence base in terms of an umbrella review of systematic reviews from 2007 to 2017 and give recommendations for treatment for all levels of care, concentrating on developments over the last 10 years. We conclude that activating, patient-involving, and centrally acting therapies appear to be more effective than passive ones that primarily act on peripheral physiology, and we recommend stepped care approaches that translate a truly biopsychosocial approach into actual management of the patient.

Inducing Somatic Symptoms in Functional Syndrome Patients: Effects of Manipulating State Negative Affect

OBJECTIVE

Induction of negative affective states can enhance bodily symptoms in high habitual symptom reporters among healthy persons and in patients with irritable bowel syndrome. The aims of this study were to replicate this effect in patients with fibromyalgia and chronic fatigue syndrome and to investigate the role of moderators, focusing on alexithymia, negative affectivity, and absorption.

METHODS

Patients with fibromyalgia and/or chronic fatigue syndrome (n = 81) and HCs (n = 41) viewed series of neutral, positive, and negative affective pictures. After every picture series, participants filled out a somatic symptom checklist and rated emotions experienced during the picture series on valence, arousal, and perceived control.

RESULTS

Patients reported more somatic symptoms after viewing negative pictures (least square mean [LSM] = 19.40, standard error (SE) = 0.50) compared with neutral (LSM = 17.59, SE = 0.42, p < .001) or positive (LSM = 17.04, SE = 0.41, p < .001) pictures, whereas somatic symptom ratings of HCs after viewing negative picture series (LSM = 12.07, SE = 0.71) did not differ from ratings after viewing neutral (LSM = 11.07, SE = 0.59, p = .065) or positive (LSM = 11.10, SE = 0.58, p = .93) pictures. Negative affectivity did not moderate the symptom-enhancing effect of negative affective pictures, whereas the alexithymia factor "difficulty identifying feelings" and absorption did (p = .016 and p = .006, respectively).

CONCLUSION

Negative affective states elicit elevated somatic symptom reports in patients experiencing fibromyalgia and/or chronic fatigue syndrome. This symptom-enhancing effect is greater in patients having higher difficulty to identify feelings and higher absorption scores. The results are discussed in a predictive coding framework of symptom perception.

Effectiveness of a Stepped, Collaborative, and Coordinated Health Care Network for Somatoform Disorders (Sofu-Net): A Controlled Cluster Cohort Study

OBJECTIVE

Stepped, collaborative, and coordinated approaches have been proposed as the optimal treatment strategy for somatic symptom and related disorders, but evidence supporting this strategy is lacking. The aim of this study was to assess the effectiveness of a guideline-based health care network for patients who are at high risk of somatoform disorder (Sofu-Net).

METHODS

In a controlled, prospective, observer-blinded cluster cohort study, patients who were at high risk of somatoform disorder were recruited at 18 primary care practices in the Sofu-Net and at 15 primary care practices that provided care as usual (CAU). The primary outcome at 6-month follow-up was the rate at which the patients received mental health treatment since the establishment of Sofu-Net. The secondary outcomes included the patients' clinical symptom severity.

RESULTS

A total of 119 patients in the Sofu-Net intervention group and 100 patients in the CAU control group who were at high risk of somatoform disorder were followed for 6 months. A significantly greater proportion of Sofu-Net patients than CAU patients received mental health treatment (47.9% versus 31.0%; odds ratio = 1.96; 95% confidence interval, 1.07-3.58). However, the Sofu-Net group did not show greater reductions in clinical symptom burden compared with the CAU group.

CONCLUSIONS

The treatment of somatoform disorders within a guideline-based health care network resulted in increased rates of mental health treatment but failed to improve patient clinical outcomes. Future investigations are needed to investigate the combined value of health care networks with specialized psychotherapy interventions in patients at high risk of somatic symptom and related disorders.

Persistent Physical Symptoms as Perceptual Dysregulation: A Neuropsychobehavioral Model and Its Clinical Implications

OBJECTIVE

The mechanisms underlying the perception and experience of persistent physical symptoms are not well understood, and in the models, the specific relevance of peripheral input versus central processing, or of neurobiological versus psychosocial factors in general, is not clear. In this article, we proposed a model for this clinical phenomenon that is designed to be coherent with an underlying, relatively new model of the normal brain functions involved in the experience of bodily signals.

METHODS

Based on a review of recent literature, we describe central elements of this model and its clinical implications.

RESULTS

In the model, the brain is seen as an active predictive processing or inferential device rather than one that is passively waiting for sensory input. A central aspect of the model is the attempt of the brain to minimize prediction errors that result from constant comparisons of predictions and sensory input. Two possibilities exist: adaptation of the generative model underlying the predictions or alteration of the sensory input via autonomic nervous activation (in the case of interoception). Following this model, persistent physical symptoms can be described as "failures of inference" and clinically well-known factors such as expectation are assigned a role, not only in the later amplification of bodily signals but also in the very basis of symptom perception.

CONCLUSIONS

We discuss therapeutic implications of such a model including new interpretations for established treatments as well as new options such as virtual reality techniques combining exteroceptive and interoceptive information.

Treatment course and its predictors in patients with somatoform disorders: A routine outcome monitoring study in secondary psychiatric care

AIM

Somatoform disorders are common and often chronic. It would be helpful to distinguish those patients who are likely to have a positive treatment course from those who are likely to follow a negative course. Such studies of different somatoform disorders are scarce, especially in secondary psychiatric care. This study examined the 6-month treatment course of psychological, physical symptoms, and functioning, and its predictors in a naturalistic sample of secondary psychiatric care outpatients with somatoform disorders.

METHOD

The present study used routine outcome monitoring data of patients with somatoform disorders regarding their 6-month treatment course of psychological and physical symptoms as well as functioning. The following patient groups were included: total group of somatoform disorders (N = 435), and undifferentiated somatoform disorder (N = 242), pain disorder (N = 102), body dysmorphic disorder (N = 51), and hypochondriasis (N = 40). Measures were Mini-International Neuropsychiatric Interview plus, Brief Symptom Inventory, Montgomery-Ǻsberg Depression Rating Scale, Brief Anxiety Scale, Short Form Health Survey 36, and Physical Symptom Checklist (PSC).

RESULTS

The study population generally showed high co-morbidity, especially with anxiety and mood disorders. The PSC total score, body dysmorphic disorder, and hypochondriasis were significant predictors for the treatment course of symptoms (Brief Symptom Inventory), whereas the PSC total score was the only significant predictor for the course of functioning (Short Form Health Survey 36).

CONCLUSION

Secondary psychiatric care outpatients with somatoform disorders showed high co-morbidity with anxiety and mood disorders, and an unfavourable 6-month course of both symptoms and functioning. Clinical implications are discussed, such as additional treatment of co-morbidity in somatoform disorders.

Variation of Functional Neurological Symptoms and Emotion Regulation with Time

INTRODUCTION

The present study addressed the variation of emotion regulation in the context of functional neurological symptom disorder (FNSD) by examining changes of functional neurological symptoms (FNS), general psychological strain, alexithymia, emotion regulation strategies, and cortical correlates of emotion regulation in the context of a standard inpatient treatment program.

METHODS AND MATERIALS

Self-report data on FNS, general psychological strain, alexithymia, emotion regulation strategies, and cortical correlates of an experimentally induced emotion regulation task (participants either passively watched unpleasant and neutral pictures or regulated their emotional response to unpleasant pictures using pre-trained reappraisal, while an electroencephalogram was recorded) were compared between 19 patients with FNSD and 19 healthy comparison participants (HC) before and after a 4-week standard treatment protocol that included a combination of (individual and group) psychotherapies and functional treatments (such as physiotherapy) or a 4-week interval in HC, respectively.

RESULTS

General psychological strain did not decrease significantly in FNSD patients. Changes in emotion regulation in FNSD patients were constrained to an increase in self-reported use of cognitive reappraisal strategies. Subjective symptom intensity in FNSD patients varied with alexithymia pretreatment, but did not decrease significantly. Cortical activity in the time and frequency-domain distinguished passive watching of neutral and unpleasant pictures and regulating emotional responses upon unpleasant pictures from passively watching them without difference between groups and/or time.

DISCUSSION

Over the investigated time interval, augmented habitual cognitive emotion regulation suggests an alleviation of emotion processing deficits, but no significant symptom decrease. More controlled and prolonged treatment studies would be needed to determine whether and how a specific contribution of treatment-related changes of emotion regulation and FNS might be inferred.

Impaired emotion processing and a reduction in trust in patients with somatic symptom disorder

There is accumulating evidence for deficits in the perception and regulation of one's own emotions, as well as the recognition of others' emotions in somatic symptom disorder (SSD). However, investigations of SSD focusing on specific aspects of emotion processing and how these might interact are missing. We included 35 patients with SSD and 35 healthy controls who completed questionnaires on the perception and regulation of their own emotions, as well as experimental investigations of emotion recognition and trust. In line with previous studies, our results show that SSD patients in comparison to healthy controls have difficulties in the identification and description of own feelings (η_p²  = .381 and η_p²  = .315). Furthermore, we found that patients apply less cognitive reappraisal (η_p²  = .185) but tend to use more expressive suppression (η_p²  = .047). In contrast to previous studies, we found SSD patients to perform superior in emotion recognition, in particular for anger (d = 0.40). In addition, patients with SSD invested less in a trust game (d = 0.73). These results point to a higher sensitivity for negative emotions and less trust in others. Further, these findings suggest a dissociation between the ability to recognize one's own emotions versus others' emotions in SSD. Future interventions targeting emotion processing in SSD might focus on the identification of one's own emotions, prior to the training of emotion regulation.

Increasing the treatment motivation of patients with somatic symptom disorder: applying the URICA-S scale

BACKGROUND

Therapeutic intervention programs for somatic symptom disorder (SSD) show only small-to-moderate effect sizes. These effects are partly explained by the motivational problems of SSD patients. Hence, fostering treatment motivation could increase treatment success. One central aspect in SSD patients might be damage to motivation because of symptomatic relapses. Consequently, the aim of the present study was to investigate associations between motivational relapse struggle and therapeutic outcome in SSD patients.

METHODS

We assessed 84 inpatients diagnosed with SSD in the early, middle and late stages of their inpatient treatment. The maintenance subscale of the University of Rhode Island Change Assessment-Short (URICA-S) was applied as a measure to assess motivational relapse struggle. Additionally, patients completed measures of treatment outcome that focus on clinical symptoms, stress levels and interpersonal functioning.

RESULTS

The results from multiple regression analyses indicate that higher URICA-S maintenance scores assessed in early stages of inpatient treatment were related to more negative treatment outcomes in SSD patients.

CONCLUSIONS

SSD patients with ambivalent treatment motivation may fail in their struggle against relapse over the course of therapy. The URICA-S maintenance score assessed at therapy admission facilitated early identification of SSD patients who are at greater risk of relapse. Future studies should incorporate randomized controlled trials to investigate whether this subgroup could benefit from motivational interventions that address relapse.

Early response in cognitive-behavior therapy for syndromes of medically unexplained symptoms

BACKGROUND

Early dramatic treatment response suggests a subset of patients who respond to treatment before most of it has been offered. These early responders tend to be over represented among those who are well at termination and at follow-up. Early response patterns in psychotherapy have been investigated only for a few of mental disorders so far. The main aim of the current study was to examine early response after five therapy-preparing sessions of a cognitive behavior therapy (CBT) for syndromes of medically unexplained symptoms (MUS).

METHODS

In the context of a randomized, waiting-list controlled trial 48 patients who suffered from ≥3 MUS over ≥6 months received 5 therapy-preparing sessions and 20 sessions of CBT for somatoform disorders. They completed self-report scales of somatic symptom severity (SOMS-7 T), depression (BDI-II), anxiety (BSI), illness anxiety and behavior (IAS) at pre-treatment, after 5 therapy-preparing sessions (FU-5P) and at therapy termination (FU-20 T).

RESULTS

The current analyses are based on data from the treatment arm only. Repeated measure ANOVAs revealed a significant decrease of depression (d = 0.34), anxiety (d = 0.60), illness anxiety (d = 0.38) and illness behavior (d = 0.42), but no change of somatic symptom severity (d = -0.03) between pre-treatment and FU-5P. Hierarchical linear multiple regression analyses showed that symptom improvements between pre-treatment and FU-5P predict a better outcome at therapy termination for depression and illness anxiety, after controlling for pre-treatment scores. Mixed-effect ANOVAs revealed significant group*time interaction effects indicating differences in the course of symptom improvement over the therapy between patients who fulfilled a reliable change (i.e., early response) during the 5 therapy-preparing sessions and patients who did not reach an early reliable change. Demographic or clinical variables at pre-treatment were not significantly correlated with differential scores between pre-treatment and FU-5P (-.23 ≤ r ≤ .23).

CONCLUSIONS

Due to several limitations (e.g., small sample size, lack of a control group) the results of this study have to be interpreted cautiously. Our findings show that reliable changes in regard to affective-cognitive and behavioral variables can take place very early in CBT of patients with distressing MUS. These early changes seem to be predictive of the outcome at therapy termination. Future studies are needed in order to replicate our results, and to identify mechanisms of these early response patterns in somatoform patients.

Emotion dysregulation in hypochondriasis and depression

BACKGROUND

The aim of this study was to explore whether certain aspects of emotion dysregulation (i.e., facets of alexithymia and rumination) are more closely linked to hypochondriasis than to depression and vice versa.

METHODS

Nineteen patients with hypochondriasis (HYP), 33 patients with depression, and 52 healthy control participants completed the Toronto Alexithymia Scale, the Response Styles Questionnaire, and additional symptom and illness behaviour scales. A clinical interview was used to establish DSM-IV diagnoses and to exclude all cases with more than one axis I diagnosis.

RESULTS

Depression patients reported more difficulties describing feelings and more symptom- and self-focused rumination than both HYP patients and healthy individuals, whereas HYP patients differed only from healthy individuals in regard to more difficulties in identifying feelings and more symptom-focused rumination. Multiple regression analyses, including all assessed facets of emotion dysregulation, showed that the degree of somatoform features (somatic symptoms, health anxiety, and illness behaviour) was specifically predicted by higher difficulties in identifying feelings scores, whereas depressive symptom levels were specifically predicted by higher rumination scores.

CONCLUSIONS

Specific associations were found between difficulties in identifying feelings and key features of HYP, whereas depression was linked to a more generalized pattern of emotion regulation deficits.

Emotion dysregulation can be found in hypochondriasis and depression Difficulties in identifying own feelings are specifically linked to somatic symptoms, health anxiety, and illness behaviour, whereas a more generalized pattern of emotion dysregulation is found in relation to depression Further research is needed to investigate whether the effectiveness of current treatments for depression, hypochondriasis, health anxiety, and related disorders could be improved by additional emotion regulation interventions.

Health care utilization in outpatients with somatoform disorders: Descriptives, interdiagnostic differences, and potential mediating factors

OBJECTIVE

Somatoform disorders are characterized by increased health care utilization producing high health costs. The aim of this study was to assess facets of and interdiagnostic differences in health care use in somatoform disorders and to examine health anxiety, symptom-related disability, depression, and phobic anxiety as potential mediating factors of the relationship between somatization and health care use.

METHOD

An outpatient sample of N=254 patients with somatoform disorders was investigated by analyzing different facets of their health care use over the last 12months. Multiple mediation analyses were applied.

RESULTS

Participants reported a mean of 28.02 doctor visits over the last year. Patients fulfilling criteria of DSM-IV somatization disorder had a significantly higher number of doctor visits than patients with undifferentiated somatoform, and somatoform pain disorder, all p≤.006. In most health care use variables, patients with comorbid mental disorders did not differ from patients without comorbidities. The mediation model on the effect of all mediator variables on the relationship between somatization and health care use reached significance (b=0.32, 95% CI: 0.0576, 0.6435). Surprisingly, specific mediator effects were found for health anxiety (b=0.06, 95% CI: 0.0004, 0.1505) and disability (b=0.18, 95% CI: 0.0389, 0.3530), but not for depression and phobic anxiety.

CONCLUSIONS

Health anxiety and symptom-related disability should be further considered when investigating potential etiological factors of increased health care use.

The mediating effects of cognitive emotion regulation strategies on the relationship between alexithymia and physical symptoms: Evidence from Iranian asthmatic patients

Asthma is a chronic and episodic psychosomatic disease whose symptoms include coughing, wheezing, chest tightness, and shortness of breath. The present study aimed to investigate the effects of cognitive emotion regulation strategies (CERS) as mediators on the relationships between alexithymia subscales and physical symptoms (PS). 300 asthmatic patients (males=42.7%, females=57.3%, age _range=16-65, mean _age=29.40) and 100 normal controls participated in the study and completed the demographic questionnaire, the Cognitive Emotion Regulation Questionnaire (CERQ), the Persian version of the Toronto Alexithymia Scale (FTAS-20), and the Powell & Enright Physical Symptoms Inventory (PSI). Asthmatic patients showed higher scores on all three alexithymia subscales including difficulty in identifying feelings (DIF), difficulty in describing feelings (DDF), and externally oriented thinking (EOT) as well as non-adaptive CERS than normal controls. On the other hand, normal controls earned higher means in adaptive CERS. Results revealed that each of the three alexithymia subscales had indirect effects on PS through the non-adaptive cognitive emotion regulation strategy of catastrophizing. It is concluded that alexithymia can intensify PS through catastrophizing in asthmatic patients.

Psychologic treatment of functional neurologic disorders

The management of patients with functional neurologic disorders poses many challenges. Psychologic treatments may well start at the point of delivery of the diagnosis, when careful explanations about the nature of the disorder have to be given to the patient and possibly also relatives/carers. Different conceptual models may assist in explaining the factors underlying the presentation, two of which (functional and dissociative) are briefly outlined here. The challenges for neurologists and psychiatrists of delivering a psychologic formulation as part of the diagnosis delivery are considered, along with the importance of clear communication between professionals involved in the patient's care. Existing literature on treatments incorporating psychologic components suggests that, despite limitations in the study designs and the potential bias in some outcome evaluations, there is evidence to support the use of psychologic interventions for at least some functional neurologic disorders, although larger and better-designed studies are required in this area.
