A unified Internet-delivered exposure treatment for undifferentiated somatic symptom disorder: single-group prospective feasibility trial

BackgroundExposure-based psychological treatment appears to have beneficial effects for several patient groups that commonly report distress related to persistent somatic symptoms. Yet exposure-based treatment is rarely offered in routine care. This may be because existing treatment protocols have been developed for specific symptom clusters or specific unwanted responses to somatic symptoms, and many clinics do not have the resources to offer all these specialised treatments in parallel. In preparation for a randomised controlled trial, we investigated the feasibility of a new and unified Internet-delivered exposure treatment (OSF.io: cnbwj) for somatic symptom disorder regardless of somatic symptom domain (e.g. cardiopulmonary, fatigue, gastrointestinal, pain), combination of unwanted emotions (e.g. anger, anxiety, fear, shame) and whether somatic symptoms are medically explained or not. We hypothesised that a wide spectrum of subgroups would show interest, that the treatment would be rated as credible, that adherence would be adequate, that the measurement strategy would be acceptable and that there would be no serious adverse events.MethodsSingle-group prospective cohort study where 33 self-referred adults with undifferentiated DSM-5 somatic symptom disorder took part in 8 weeks of unified Internet-delivered exposure treatment delivered via a web platform hosted by a medical university. Self-report questionnaires were administered online before treatment, each week during treatment, post treatment and 3 months after treatment.ResultsParticipants reported a broad spectrum of symptoms. The Credibility/Expectancy mean score was 34.5 (SD = 7.0, range: 18–47). Participants completed 91% (150/165) of all modules and 97% of the participants (32/33) completed at least two exposure exercises. The average participant rated the adequacy of the rationale as 8.4 (SD = 1.5) on a scale from 0 to 10. The post-treatment assessment was completed by 97% (32/33), and 84% (27/32) rated the measurement strategy as acceptable. The Client Satisfaction Questionnaire mean score was 25.3 (SD = 4.7, range: 17–32) and no serious adverse events were reported. Reductions in subjective somatic symptom burden (the Patient Health Questionnaire 15; d = 0.90) and symptom preoccupation (the somatic symptom disorder 12; d = 1.17) were large and sustained.ConclusionsDelivering a unified Internet-delivered exposure-based treatment protocol for individuals with undifferentiated somatic symptom disorder appears to be feasible.Trial registrationClinicalTrials.gov, NCT04511286.

Is Therapist Support Needed? Comparing Therapist- and Self-Guided Internet-Based CBT for Somatic Symptom Distress (iSOMA) in Emerging Adults

Persistent somatic symptoms of varying etiology are very common in emerging adults and can lead to distress and impairment. Internet-delivered interventions could help to prevent the burden and chronicity of persistent somatic symptoms. This study investigated the impact of therapist guidance on the effectiveness of a cognitive-behavioral Internet intervention for somatic symptom distress (iSOMA) in emerging adults, as a secondary analysis of a two-armed randomized controlled trial. We included 149 university students (83.2% female, 24.60 yrs) with varying degrees of somatic symptom distress who were either allocated to the 8-week intervention with regular, written therapeutic guidance (iSOMA guided) or to the control group (waitlist), which was afterwards crossed over to receive iSOMA with guidance-on-demand (iSOMA-GoD). Primary outcomes were somatic symptom distress (assessed by the PHQ-15) and psychobehavioral symptoms of the somatic symptom disorder (assessed by the SSD-12) at pre- and post-treatment. Secondary outcomes included depression, anxiety, and disability. Both treatments showed statistically significant pre-post improvements in primary (iSOMA-guided: d = 0.86–0.92, iSOMA-GoD: d = 0.55–0.63) and secondary outcomes. However, intention-to-treat analysis revealed non-significant between-group effects for all outcomes (ps ≥ .335), after controlling for confounding variables, and effect sizes were marginal (d = −0.06 to 0.12). Overall, our findings indicate that Internet-delivered cognitive behavioral therapy with regular guidance is not unequivocally superior to guidance-on-demand in alleviating somatic symptom distress and associated psychopathology in emerging adults. As a next step, non-inferiority studies are needed to test the robustness of these findings and their impact on clinical populations.

Lost in fragmentation — care coordination when somatic symptoms persist: a qualitative study of patients’ experiences

BackgroundGPs can play a central role in the care of patients with persistent somatic symptoms (PSS). To date, little is known about these patients’ experiences relating to their coordination of care.AimTo explore the experiences of patients with PSS relating to coordination of care — in particular by their GP — during their illness trajectory.Design and settingThis qualitative study was carried out from January to April 2019 in the Netherlands as part of a multicentre prospective cohort study on the course of PSS (PROSPECTS).MethodThematic content analysis of 15 interviews.ResultsThree themes were identified: care fragmentation during the diagnostic trajectory; transition from the search for a cure to coping; and reframing to coping: GPs’ role in facilitating supportive care. Patients experienced a lack of collaboration from healthcare workers during the diagnostic trajectory. Guidance by their GP in a process of shared decision making was positively valued by patients. Moving the focus from searching for a cure to coping with symptoms was described as a ‘personal endeavour’, made even more challenging by the ongoing uncertainty experienced by patients. When reframing to coping, the extent to which patients felt aligned with their GP played an important role in whether their supportive care request was met.ConclusionPatients experienced difficulties when navigating the diagnostic trajectory and shifting to coping. The findings of this study underline the importance of collaboration between GPs and other healthcare professionals during the diagnostic trajectory. The authors recommend that GPs provide proactive guidance and are sensitive to patients who shift to coping by providing them with supportive care in a process of shared decision making.

Biopsychosocial correlates of persistent somatic symptoms in patients with chronic kidney disease – results of the Hamburg City Health Study (HCHS)

Persistent somatic symptoms (PSS) in patients with chronic kidney disease (CKD) are present in all stages and influence the patients' quality of life, morbidity and mortality. Aim of this study was to unravel interactions between biopsychosocial factors and symptom burden in patients with CKD. This cross-sectional study analysed individuals with impaired renal function (GFR <60 mL/min/1,73 m2) out of the first cohort (10,000 individuals) of the epidemiological Hamburg City Health Study (HCHS). As primary outcome somatic symptom burden (PHQ-15) was analysed. As potential correlates, biological (e.g., renal function, comorbidities), psychological (e.g., depression, anxiety, quality of life), and sociodemographic factors were analysed in a multivariate prediction model. Of the cohort, 588 participants (5,9%) had a reduced GFR. Of these, only 159 (27%) were aware of their renal dysfunction. Individuals with reduced GFR reported higher symptom burden compared to healthy controls (mean PHQ-15 (SD): 4,8 (3,9) vs. 5,4 (4,0), p = 0,002, Cohen's d = 0.15). In individuals with reduced kidney function higher symptom burden correlated with reduced GFR ( r = −0.17, p < 0.001). In the multivariate prediction model, GFR was not correlated with symptom burden, which was predicted by depressive symptoms, self-reported coronary heart disease and quality of life. This shows that symptom burden is only marginally related to renal function, while other biopsychosocial factors might play a more important role. Therefore, it is important to take a biopsychosocial perspective on PSS in CKD.

Potentially traumatic events, social support and burden of persistent somatic symptoms: A longitudinal study

ObjectivePsychological trauma is a well-known risk factor for the onset of persistent somatic symptoms (PSS). In contrast, little is known on the relation between potentially traumatic events (PTEs) and the severity of PSS, and on the protective effect of social support. We aimed to: (i) determine whether childhood, adulthood and recent PTEs are associated with burden of PSS over four years of follow-up; (ii) examine associations of multiple and cumulative (in childhood and adulthood) exposure to PTEs with burden of PSS; and (iii) determine whether social support modifies these associations. MethodsLongitudinal data of 322 patients with PSS were analyzed. PTEs (Life Events Questionnaire) and social support (Social Support Scale) were assessed at baseline. Burden of PSS was measured in terms of symptom severity (PHQ-15) and physical functioning (RAND-36 PCS) at six repeated measurements over a four-year interval. Associations were analyzed using longitudinal mixed model analysis. ResultsPatients with multiple childhood PTEs reported higher burden of PSS over four-year time. Adulthood PTEs were associated with burden of PSS in patients with, but not in patients without childhood PTEs. Recent PTEs were not associated with burden over time. Social support did not modify any of the associations. ConclusionsPTEs are associated with higher burden of PSS over time, in addition to the well-known association with the onset of PSS. PTEs in early life and cumulative exposure to PTEs in childhood and adulthood are associated with higher burden over time in patients with PSS. Social support did not attenuate the associations.

Somatosensory amplification moderates the efficacy of internet-delivered CBT for somatic symptom distress in emerging adults: Exploratory analysis of a randomized controlled trial

ObjectiveWhile studies mainly provide positive evidence for the efficacy of internet-delivered cognitive-behavioral therapy (ICBT) for various persistent somatic symptoms, it remains largely unclear for whom these interventions work or not. This exploratory analysis aimed to identify moderators for the outcome between ICBT for somatic symptom distres and a waitlist control group (WL) in a vulnerable target group of emerging adults. MethodsBased on data from a randomized controlled trial on 156 university students with varying degrees of somatic symptom distress who were allocated to either an eight-week, therapist guided ICBT (iSOMA) or to the WL, we examined pretreatment demographic characteristics, health-related variables (e.g., somatic symptom duration), mental distress (e.g., depression, anxiety) and cognitive-emotional factors (emotional reactivity, somatosensory amplification) as candidate moderators of the outcome, somatic symptom distress (assessed by the Patient Health Questionnaire, PHQ-15) from pre- to posttreatment. ResultsSomatosensory amplification (assessed by the Somatosensory Amplification Scale, SSAS) moderated the outcome in favor of iSOMA (B = −0.17, SE = 0.08, p = 0.031), i.e., higher pretreatment somatosensory amplification was associated with better outcome in the active compared to the control intervention. No significant moderation effects were found among demographic characteristics, health-related variables, or mental distress. ConclusionOur findings suggest that an internet-delivered CBT for somatic symptom distress should be preferred over no active treatment particularly in individuals with moderate to high levels of somatosensory amplification, which as a next step should be tested against further treatments and in clinical populations.Trial registration: German Clinical Trials Register (DRKS00014375).

Assessment and Management of Long COVID.

Almost two years into the pandemic, the scientific and healthcare communities continue to learn a great deal regarding COVID-19, the disease produced by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Broad variability during acute COVID-19 infection is seen, ranging from asymptomatic presentation to death. The vast majority of individuals who develop COVID-19 return to their pre-COVID-19 baseline within several weeks. However, a portion of patients will develop a post-COVID-19 syndrome of persistent cognitive, somatic, and behavioral symptoms. This syndrome, designated as post-acute sequelae of SARS-CoV-2 infection, is more commonly known as long COVID. The objectives of this paper are to inform psychologists regarding our current understanding of the underlying pathophysiology of COVID-19, review criteria for range of severity during acute illness, present clinical manifestations of long haul phenomena, and discuss the emerging literature base of evidence-based treatment and management approaches.

Experiences of Patients With Hashimoto Thyroiditis Through the Lens of Compassion

Hashimoto thyroiditis (HT) is an autoimmune disease affecting mainly middle-aged women. Hormonal replacement is the most common therapy; however, it tackles only the functionality of the thyroid and not the autoimmunity components. Thus, patients experience persistent somatic and psychological symptoms, thereby affecting their quality of life. The cause of HT remains uncertain. Primary evidence suggests that adverse experiences in childhood are associated with autoimmune disease manifestation in adulthood; therefore, the effect of early adverse events on disease course needs to be explored. This paper explored patients’ early life events and everyday experiences through the lens of compassion, as defined in compassion-focused therapy (CFT). In this study, nine participants were interviewed, and the transcribed interviews were analyzed using Thematic Analysis. Qualitative analysis indicated that patients exhibited increased psychological distress and a lack of understanding from others. Common patterns of experiences and behaviors were identified, such as the lack of compassion and affiliation between significant others and themselves. Therefore, including psychological care in the therapeutic process of HT would improve patients’ well-being and quality of life. In particular, cultivating compassion could be a promising strategy for disease prevention and the healthy functioning of patients.

The Interoceptive Sensitivity and Attention Questionnaire: Evaluating Aspects of Self-Reported Interoception in Patients With Persistent Somatic Symptoms, Stress-Related Syndromes, and Healthy Controls.

This study aimed to validate the Interoceptive Sensitivity and Attention Questionnaire (ISAQ), a 17-item self-report measure assessing sensitivity and attention to interoceptive signals. In study 1, exploratory and confirmatory factor analysis was performed in a student convenience sample (n = 1868). In study 2, ISAQ data of a healthy sample (n = 144) and various patient groups experiencing stress-related syndromes (overstrain, n = 63; burnout, n = 37; panic disorder [PD]. n = 60) and/or persistent somatic symptoms in daily life (irritable bowel syndrome, n = 38; fibromyalgia and/or chronic fatigue syndrome, n = 151; medically unexplained dyspnea [MUD], n = 29) were compared. Three subscales were revealed: (F1) sensitivity to neutral bodily sensations, (F2) attention to unpleasant bodily sensations, and (F3) difficulty disengaging from unpleasant bodily sensations. Overall, patients with fibromyalgia and/or chronic fatigue syndrome and patients with MUD scored significantly higher on F1 (p = .009 and p = .027, respectively) and F2 (p = .002 and p < .001, respectively) than healthy controls. Patients with PD had higher scores on subscales F2 (p < .001) and F3 (p < .001) compared with healthy controls, as well as higher scores on F2 compared with all other patient groups (pPD versus MUD = .008; all other p values < .001). Interoceptive sensibility-the self-reported aspect of interoception-is not a homogeneous or unitary construct. The subscales of the ISAQ differentiate healthy controls from patients with persistent somatic and/or stress-related complaints in daily life and distinguish different patient groups. The ISAQ can be used as a concise, reliable, and clinically relevant research tool to further disentangle adaptive and maladaptive aspects of interoceptive ability.

Mental and Somatic Health Care Use in Persistent Somatic Symptoms: 4-Year Follow Up of the Network for Somatoform and Functional Disorders (Sofu-Net)

The stepped, coordinated, interdisciplinary Health Network for Somatoform and Functional Disorders (Sofu-Net) was developed to provide guideline-based care for patients with somatoform and functional disorders. This controlled cluster cohort study evaluated patients' mental and somatic health care use, clinical outcomes, and their predictors at 4-years follow-up. 219 patients at risk for somatoform disorders from Sofu-Net practices (n=119) and control practices (n=100) were resurveyed after 4 years using structured interviews. Outcomes were mental and somatic health care use, somatic symptom burden and depressive symptoms. 127 patients (n=74 Sofu-Net, n=53 controls) were followed up. Compared with the control group, Sofu-Net patients were significantly more likely to be referred to psychotherapy (55.4 vs. 35.8%). Younger age and more frequent GP consultations on the occasion of psychosocial problems predicted mental health care use. No difference was found between the two groups in the severity of clinical symptoms or in the extent of somatic health care use. Significant predictors were the number of somatic diseases, increased fear of illness, female gender, increased depressive symptomatology, low physical and mental quality of life. In the long term, the coordinated and interdisciplinary network structure succeeded in more successfully referring high-risk patients to psychotherapy. The role of the primary care physician proved to be important. However, this was not accompanied by an improvement in the patients' clinical condition or a decrease in outpatient physician utilization.

Development and User Experiences of a Biopsychosocial Interprofessional Online Course on Persistent Somatic Symptoms.

Background: Communication between healthcare providers and patients with persistent somatic symptoms (PSS) is frequently hampered by mutual misunderstanding and dissatisfaction.Methods: We developed an online, interprofessional course to teach healthcare providers the knowledge, skills, and attitude they need to diagnose and treat PSS in a patient-centered manner based on the biopsychosocial model. The course consisted of six modules of 45–60 min. Each module contained different types of assignments, based on six cases: videos, discussion boards, reading assignments, polls, and quizzes. For this study, we included (1) medical residents, following the course as part of their residency training, and (2) healthcare providers (general practitioners, medical specialists, physiotherapists, nurses, and psychologists), following the course as continuing vocational training. Throughout the course, participants were asked to fill out online surveys, enquiring about their learning gains and satisfaction with the course.Results: The biopsychosocial approach was integrated across the modules and teached health care workers about recent insights on biological, psychological and social aspects of PSS. In total, 801 participants with a wide variety in clinical experience started the course; the largest groups of professionals were general practitioners (N = 400), physiotherapists (N = 124) and mental healthcare workers (N = 53). At the start of the course, 22% of the participants rated their level of knowledge on PSS as adequate. At the end of the course, 359 participants completed the evaluation questionnaires. Of this group, 81% rated their level of knowledge on PSS as adequate and 86% felt that following the course increased their competencies in communicating with patients with PSS (N = 359). On a scale from 1 to 10, participants gave the course a mean grade of 7.8 points. Accordingly, 85% stated that they would recommend the course to a colleague.Conclusion: Our course developed in a co-design process involving multiple stakeholders can be implemented, is being used, and is positively evaluated by professionals across a variety of health care settings.

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..

The general practitioners perspective regarding registration of persistent somatic symptoms in primary care: a survey

BackgroundPersistent somatic symptoms (PSS) are common in primary care and often accompanied by an increasing disease burden for both the patient and healthcare. In medical practice, PSS is historically considered a diagnosis by exclusion or primarily seen as psychological. Besides, registration of PSS in electronic health records (EHR) is ambiguous and possibly does not reflect classification adequately. The present study explores how general practitioners (GPs) currently register PSS, and their view regarding the need for improvements in classification, registration, and consultations.MethodDutch GPs were invited by email to participate in a national cross-sectional online survey. The survey addressed ICPC-codes used by GPs to register PSS, PSS-related terminology added to free text areas, usage of PSS-related syndrome codes, and GPs’ need for improvement of PSS classification, registration and care.ResultsGPs (n = 259) were most likely to use codes specific to the symptom presented (89.3%). PSS-related terminology in free-text areas was used sparsely. PSS-related syndrome codes were reportedly used by 91.5% of GPs, but this was primarily the case for the code for irritable bowel syndrome. The ambiguous registration of PSS is reported as problematic by 47.9% of GPs. Over 56.7% of GPs reported needing additional training, tools or other support for PSS classification and consultation. GPs also reported needing other referral options and better guidelines.ConclusionsRegistration of PSS in primary care is currently ambiguous. Approximately half of GPs felt a need for more options for registration of PSS and reported a need for further support. In order to improve classification, registration and care for patients with PSS, there is a need for a more appropriate coding scheme and additional training.

Psychobiological Mechanisms in Somatic Symptom Disorder and Depressive Disorders: An Ecological Momentary Assessment Approach.

Persistent somatic symptoms cause strong impairment in persons with somatic symptom disorder (SSD) and depressive disorders (DDs). Specific negative psychological factors (NPFs), such as catastrophizing, negative affectivity, and behavioral avoidance, are assumed to contribute to this impairment and may maintain symptoms via dysregulations of biological stress systems. We examined the associations between NPF and somatic symptoms in the daily life of women with SSD or DD and investigated the mediating role of psychobiological stress responses. Twenty-nine women with SSD and 29 women with DD participated in an ecological momentary assessment study. For 14 days, intensity of and impairment by somatic symptoms, NPF, and stress-related biological measures (cortisol, alpha-amylase) were assessed five times per day using an electronic device and saliva samples. Multilevel models were conducted. The greater the number of NPF, the higher the concurrent and time-lagged intensity of and impairment by somatic symptoms in both groups (12.0%-38.6% of variance explained; χ2(12) p < .001 for all models). NPFs were associated with higher cortisol levels in women with DD and with lower levels in women with SSD (interaction NPF by group: B = -0.04, p = .042 for concurrent; B = -0.06, p = .019 for time-lagged). In women with SSD, lower cortisol levels were associated with higher intensity at the next measurement time point (group by cortisol: B = -1.71, p = .020). No mediation effects were found. NPFs may be considered as transdiagnostic factors in the development and treatment of impairing somatic symptoms. Our findings will allow the development of new treatment strategies that use ecological momentary intervention approaches focusing on NPF.
