Psychological risk factors of somatic symptom disorder: A systematic review and meta-analysis of cross-sectional and longitudinal studies. J Psychosom Res 2024; 181:111608. [PMID: 38365462 DOI: 10.1016/j.jpsychores.2024.111608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 02/07/2024] [Accepted: 02/10/2024] [Indexed: 02/18/2024]
Abstract
OBJECTIVE Current diagnostic concepts of somatic symptom disorder (SSD) in DSM-5 and bodily distress disorder (BDD) in ICD-11 require certain psychological criteria, but researchers have called for further specification. Therefore, in a first step, this systematic review and meta-analysis aimed to summarize the current evidence on psychological factors associated with SSD/BDD and/or disorder-relevant clinical outcomes such as symptom severity and impairment. METHODS Psychological factors were systematically searched using Pubmed, Cochrane Library and Psycinfo via EBSCO. Studies providing original data in English or German, after 2009 were included. Cross-sectional, cohort and case-control studies investigating at least one psychological factor in individuals with SSD/BDD in the context of disorder-relevant outcomes were included. RESULTS Forty-three eligible studies (n = 3760 patients) in SSD (none in BDD) provided data on at least one psychological factor, 37 in case-control format, 10 cross-sectional and 5 longitudinal. Meta-analyses of the case-control studies found patients with SSD to be more impaired by depression (SMD = 1.80), anxiety (SMD = 1.55), health anxiety (SMD = 1.31) and alexithymia (SMD = 1.39), compared to healthy controls. Longitudinal results are scarce, mixed, and require refining, individual studies suggest self-concept of bodily weakness, anxiety and depression to be predictive for persistent SSD and physical functioning. CONCLUSION This review provides a detailed overview of the current evidence of psychological factors in relation to SSD/BDD. Future studies on SSD and BDD should include under-studied psychological factors, such as negative affect, fear avoidance, or emotion regulation. More longitudinal studies are needed to assess the predictive value of these factors.

Abstract
Amidst broad changes to the somatic disorder diagnoses, DSM-IV pain disorder was absorbed into DSM-5's somatic symptom disorder (SSD) as a specifier. However, clinical research testing of its use for the chronic pain population has been limited and its utility remains inconclusive. Using the exemplar of fibromyalgia, this article evaluates the validity, reliability, clinical utility, and acceptability of the SSD pain specifier. The diagnosis appears to have moderate validity but low specificity for the fibromyalgia population. The pain specifier has neither undergone sufficient field testing nor been evaluated for use by medical providers, with available data suggesting low reliability. Further research is needed to establish clinical utility via assessment of differential treatment outcomes. Concerns about social, legal, and economic consequences of classifying pain patients with a mental health diagnosis are outstanding. The current SSD criteria should be used with caution among the fibromyalgia patient population until its application for chronic pain has been further researched.

Abstract
OBJECTIVE This study aimed to develop and validate the Korean version of the Somatic Symptom Disorder-B Criteria Scale (SSD-12) in outpatients at a psychiatric clinic and assess its diagnostic accuracy. METHODS A total of 207 patients completed SSD-12. For the diagnostic accuracy of SSD-12, the somatic symptom disorder (SSD) section of the structured clinical interview for DSM-5 disorders-research version (SCID-5-RV) was used. The SSD-12 construct and concurrent validity were assessed by examining the correlations with Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), PHQ-15, 5-level EQ-5D version (EQ-5D-5L), and World Health Organization Quality of Life Brief Version (WHOQOL-BREF). RESULTS The SSD-12 had excellent internal consistency (Cronbach α=0.90). Confirmatory factor analysis revealed good fit indices for a general factor model (comparative fit index [CFI]=0.92, Tucker-Lewis index [TLI]=0.88, root mean square error of approximation [RMSEA]=0.10; 95% confidence interval [CI], 0.08-0.11) and a three-factor model (CFI=0.94, TLI=0.91, RMSEA=0.08; 95% CI, 0.07-0.10). The total SSD-12 score was significantly correlated with anxiety (GAD-7: r=0.53, p<0.001), depression (PHQ-9: r=0.52, p<0.001), physical symptom burden (PHQ-15: r=0.36, p<0.001), and quality of life (EQ-5D-5L: r=-0.40, p<0.001; WHOQOL-BREF: r=-0.51, p<0.001). SSD-12 demonstrated good accuracy (area under the curve=0.75, standard error=0.04; 95% CI, 0.68-0.82) with an optimal cut-off of 29. CONCLUSION The Korean SSD-12 demonstrates reliability and validity for diagnosing SSD in clinical setting.

The framework for systematic reviews on psychological risk factors for persistent somatic symptoms and related syndromes and disorders (PSY-PSS). Front Psychiatry 2023; 14:1142484. [PMID: 37091694 PMCID: PMC10113674 DOI: 10.3389/fpsyt.2023.1142484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Accepted: 03/16/2023] [Indexed: 04/25/2023] Open
Abstract
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.

Abstract
BACKGROUND In 2013, the diagnosis of somatic symptom disorder (SSD) was introduced into the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This review aims to comprehensively synthesize contemporary evidence related to SSD. METHODS A scoping review was conducted using PubMed, PsycINFO, and Cochrane Library. The main inclusion criteria were SSD and publication in the English language between 01/2009 and 05/2020. Systematic search terms also included subheadings for the DSM-5 text sections; i.e., diagnostic features, prevalence, development and course, risk and prognostic factors, culture, gender, suicide risk, functional consequences, differential diagnosis, and comorbidity. RESULTS Eight hundred and eighty-two articles were identified, of which 59 full texts were included for analysis. Empirical evidence supports the reliability, validity, and clinical utility of SSD diagnostic criteria, but the further specification of the psychological SSD B-criteria criteria seems necessary. General population studies using self-report questionnaires reported mean frequencies for SSD of 12.9% [95% confidence interval (CI) 12.5-13.3%], while prevalence studies based on criterion standard interviews are lacking. SSD was associated with increased functional impairment, decreased quality of life, and high comorbidity with anxiety and depressive disorders. Relevant research gaps remain regarding developmental aspects, risk and prognostic factors, suicide risk as well as culture- and gender-associated issues. CONCLUSIONS Strengths of the SSD diagnosis are its good reliability, validity, and clinical utility, which substantially improved on its predecessors. SSD characterizes a specific patient population that is significantly impaired both physically and psychologically. However, substantial research gaps exist, e.g., regarding SSD prevalence assessed with criterion standard diagnostic interviews.

Abstract
OBJECTIVE 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. METHODS 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. RESULTS 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. CONCLUSIONS 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.

Abstract
OBJECTIVE The diagnostic criteria of somatic symptom disorder (SSD) emphasize that somatic symptoms receive disease value once they are accompanied by excessive thoughts, feelings, or behaviors. The main objective of this study was to examine what constitutes excessiveness in psychological reactions to somatic complaints and how excessive symptom-related behavior influences self-reported health status and health care utilization. METHODS A national, representative general population survey was performed between January and March 2016 in Germany, including 2395 individuals older than 13 years. Self-report questionnaires (Somatic Symptom Scale-8, Somatic Symptom Disorder-B Criteria Scale) were used to operationalize the SSD criteria. Group differences in the daily amount of time dedicated to physical complaints were analyzed between individuals with and without SSD. Stepwise linear regression analyses were performed to predict general mental and physical health status, and health care utilization. RESULTS There was a significant effect of group (SSD yes/no) in daily time spent on symptoms, after controlling for age, sex, depression, and anxiety (F(1,2336) = 447.53, p < .001). The SSD group (n = 213) reported an average of 4 hours, whereas individuals without SSD reported 30 minutes. Results of the regression analyses showed that the combination of somatic symptoms and symptom-related psychological features is predictive of worsened self-reported physical and mental health status, and increased health care utilization. CONCLUSIONS A range of 3 to 4 hours per day spent on dealing with physical complaints seems indicative of excessiveness. If, during a clinical consultation, a patient reports such a large amount of time, a more comprehensive clinical examination of SSD should follow.

Medically unexplained symptoms in children and adolescents: Illness-related self-concept and parental symptom evaluations. J Behav Ther Exp Psychiatry 2020; 68:101565.

Abstract
BACKGROUND AND OBJECTIVES According to cognitive-behavioral models, illness-related symptom evaluations and self-concepts play a pivotal role in the development and maintenance of medically unexplained somatic symptoms (MUS). However, illness-related cognitions related to MUS have rarely been studied in children/adolescents and their parents. METHODS Seventy-eight children and adolescents (M = 14.2 years; 59% female) performed two versions of the Implicit Association Test (IAT) to measure the implicit illness-related and the implicit anxiety-related self-concept. Illness-related evaluations of unspecific symptoms were assessed via the Health Norms Sorting Task (HNST), and MUS as well as characteristics of somatic symptom disorder (SSD) via questionnaires. RESULTS MUS were significantly positively associated with the explicit (r = 0.30, p < .01) and implicit illness-related self-concept (r = 0.24, p = .04), but not with the anxiety-related self-concept (r = 0.15, p = .18). The implicit illness-related self-concept explained incremental variance in MUS (ΔR2 = 0.05, p = .04) beyond the explicit illness-related self-concept. Regarding health anxiety, parental illness-related symptom evaluations moderated the relationship between child-reported severity of MUS and health anxiety (B = 0.12, p < .01). LIMITATIONS Some measures have been adapted for childhood and adolescence, but validations on larger samples are still pending. CONCLUSIONS A disorder-specific self-concept of being ill, as well as parental symptom evaluations, seem to play an essential role in MUS and health anxiety in childhood and adolescence. Due to the importance of the top-down processes found here, the findings are in line with current predictive coding models of somatic symptom perception.

Abstract
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.

Abstract
INTRODUCTION Somatoform or somatic symptom disorders ((S)SD) are common and have a negative impact on the patients' health-related quality of life, healthcare use and costs. In primary care, which is central to the management of (S)SD, diagnosis and treatment tend to be delayed. There is a significant lack of evidence regarding the barriers in the diagnostic process of (S)SD in primary care and how interventions should be tailored to address them. The aim of this study is to analyse the diagnostic process in primary care that results in the diagnosis or non-diagnosis of a (S)SD. METHODS AND ANALYSIS This mixed methods study will investigate the topic with qualitative methods, subsequently proceeding to a quantitative phase where the initial results will be validated and/or generalised. First, focus groups will explore meanings and patterns, inconsistencies and conflicts in general practitioners' (GPs) thoughts and behaviours when diagnosing (S)SD. Second, the results of these focus groups will be used to develop interview guidelines for subsequent face-to-face interviews. Patients and their treating GPs will be interviewed separately on how they experience the history of illness, the diagnostic process and treatment. Third, based on the results of the first two study parts, a questionnaire will be derived and a nationwide survey among German GPs will be conducted, quantifying the barriers and difficulties identified before. ETHICS AND DISSEMINATION Ethics approval was obtained from the Ethics Committee of the Hamburg Medical Association, Germany (approval number PV4763). The results of this study will be disseminated through conference presentation and publications in peer-reviewed journals. TRIAL REGISTRATION NUMBER The study is registered in the German Clinical Trial Register (DRKS), DRKS-ID DRKS00009736.

Abstract
BACKGROUND DSM-5 introduced a fundamental revision of the category of somatoform disorders, which resulted in the new somatic symptom disorder (SSD) and related disorders. However, prognostic validity of SSD remains unclear, while other classification proposals, such as bodily distress disorder (BDD) or polysymptomatic distress disorder (PSDD), might be promising alternatives for the new ICD-11. Therefore, the comparison of the different approaches concerning long-term prognosis of disorder-relevant factors is of special interest. METHOD In a longitudinal design (baseline, 1-year, and 4-year follow-up), the three proposals (SSD, BDD, PSDD) were compared in an age-representative sample of the German general population (N = 321). To this end, the baseline sample was divided into three independent pairs of groups (with/without SSD, with/without BDD, with/without PSDD). It was tested how well each approach differentiated with regard to medium- and long-term healthcare utilization, number of symptoms, and impairment. RESULTS Criteria for BDD distinguished best with regard to future healthcare utilization resulting in a large-sized effect (f = 0.44) for the difference between persons with and without BDD, while SSD and PSDD revealed only medium-sized effects (f = 0.28 and f = 0.32) between subjects with and without diagnosis. The three proposals distinguished equally well with regard to future subjective impairment (between f = 0.39 and f = 0.41) and the number of reported symptoms (between f = 0.77 and f = 0.83). CONCLUSION In accordance with our data regarding prognostic validity, the current draft of the WHO group is based on the BDD proposal. However, existing limitations and weaknesses of the present proposal for the ICD-11 are further discussed.

Abstract
OBJECTIVE Little is known about autonomic nervous system activity in individuals with somatic symptom disorder (SSD) as defined by DSM-V criteria. The aims of this study were to investigate whether individuals with SSD differ from healthy controls in heart rate variability (HRV) measures of autonomic nervous system activity and whether sex has a moderating effect on this association. METHODS We recruited 168 individuals with SSD (35.1% men) and 106 healthy controls (27.4% men). Demographics, HRV, and psychological factors were measured using the Patient Health Questionnaire-15, Health Anxiety Questionnaire, Beck Depression Inventory-II (BDI-II), and Beck Anxiety Inventory. Multiple regression analysis was used to examine the association of SSD with HRV, adjusting for demographic and psychological measures. RESULTS Individuals with SSD had lower levels of total-power HRV and low-frequency HRV, but no differences in high-frequency (HF)-HRV were found. HRV differences between SSD and controls varied by sex and age (triple interaction TP-HRV β = -0.222, p < .001; low-frequency HRV β = -0.332, p < .001; and HF-HRV β = -0.167, p = .006). Whole-sample multiple regression analyses revealed significant sex differences in the magnitudes of the association between BDI-II with HF-HRV (β of sex*BDI-II: 0.761, p = .005) and analyses stratified by sex indicated that HF-HRV was significantly correlated with depression in men with SSD (r = -0.491, p < .001) but not in women with SSD (r = 0.057, p = .558). CONCLUSIONS These results suggest that patients with SSD demonstrate different patterns of HRV and the patterns of association between HRV indices and psychological factors vary between men and women.

Abstract
OBJECTIVE This study aimed (1) to describe frequencies of DSM IV somatisation disorder, undifferentiated somatoform disorder and pain disorder versus DSM 5 somatic symptom disorder (SSD) in a multi-setting population of patients with medically unexplained physical symptoms (MUPS), (2) to investigate differences in sociodemographic and (psycho)pathological characteristics between these diagnostic groups and (3) to explore the clinical relevance of the distinction between mild and moderate DSM 5 SSD. METHODS We used baseline data of a cohort of 325 MUPS patients. Measurements included questionnaires about symptom severity, physical functioning, anxiety, depression, health anxiety and illness perceptions. These questionnaires were used as proxy measures for operationalization of DSM IV and DSM 5 diagnostic criteria. RESULTS 92.9% of participants fulfilled criteria of a DSM IV somatoform disorder, while 45.5% fulfilled criteria of DSM 5 SSD. Participants fulfilling criteria of DSM 5 SSD suffered from more severe symptoms than those only fulfilling criteria of a DSM IV somatoform disorder(mean PHQ-15 score of 13.98 (SD 5.17) versus 11.23 (SD 4.71), P-value<0.001). Furthermore their level of physical functioning was significantly lower. Compared to patients with mild SSD, patients with moderate SSD suffered from significantly lower physical functioning and higher levels of depression. CONCLUSION Within a population of MUPS patients DSM 5 SSD criteria are more restrictive than DSM IV criteria for somatoform disorders. They are associated with higher symptom severity and lower physical functioning. However, further specification of the positive psychological criteria of DSM 5 SSD may improve utility in research and practice.

Abstract
Neuroimaging data have demonstrated brain functional alterations in patients with somatization disorder (SD). However, there is little information on interhemispheric resting-state functional connectivity (FC) in SD. In this study, resting-state functional magnetic resonance imaging (fMRI) and voxel-mirrored homotopic connectivity (VMHC) were applied to examine the changes of interhemispheric FC of the whole brain in patients with SD. A total of 25 first-episode, medication-naive SD patients and 28 age-, sex-, education-matched healthy controls (HC) underwent resting-state fMRI, and the data were analyzed by VMHC. Compared with HC, patients had lower VMHC in the angular gyrus/supramarginal gyrus (AG/SG) and insula. The reproducibility of the results was validated using the split-half and leave-one-out validations. No significant correlation was found between the VMHC in AG/SG or insula and clinical variables. Our findings indicate that the interhemispheric FC in the AG/SG and insula is decreased in first-episode, treatment-naive patients with SD, and thus provide new insight for disruption of interhemispheric FC in the pathophysiological mechanism of SD.

Abstract
PURPOSE OF REVIEW As a part of the its current revision of the International Classification of Diseases (ICD), the WHO is proposing major changes to the somatoform section of the chapter on Mental and Behavioral Disorders. This article reviews the basis for these changes and presents the highlights of the new category being proposed. RECENT FINDINGS As currently classified in ICD-10, somatoform disorders have major problems that limit their clinical utility. Among these are the negative criterion specifications for the diagnosis of the disorders, the rarity of the prototype categories, and the imprecise boundaries between them. To respond to these problems, a new category of Bodily Distress Disorder (BDD) is proposed to replace the current categories. The proposed category is defined by a simplified set of criterion specifications that are based on the presence of positive psycho-behavioral features. SUMMARY The new category, still in proposal stage, offers the prospect of responding to the need for a reliable diagnosis of clinically significant somatic preoccupations that are common in the community as well as in routine clinical practice. It is expected that improved diagnosis should aid the correct identification of these conditions and enhance the ability of clinicians to provide effective treatment.

Abstract
OBJECTIVE The validity and clinical utility of current research criteria of the DSM 5 category somatic symptom disorder (SSD) needs to be tested outside the setting of psychiatry. METHODS Consecutive patients with an established diagnosis of fibromyalgia syndrome (FMS) were evaluated by medical examination, psychiatric interview and self-report questionnaires in an outpatient pain medicine center. The diagnosis of SSD was established using published research criteria. The discriminative concurrent criterion validity of SSD was tested by comparing FMS-patients with and without SSD as to the amount of impairment and of health care seeking. Two clinicians blinded as to the purpose of the study, assessed the medical reports of patients after the evaluation for the determination of the need for psychotherapy based on the German FMS - guideline recommendations (clinical utility). RESULTS 25.6% of 156 patients met the criteria of SSD. Patients meeting SSD criteria scored significantly higher in a self-report measure of disability. There were no significant differences in the number of patients on sick leave or applying for disability pension and in self-reported doctor visits and physiotherapy in the previous six months. 95.0% of patients with SSD and 71.6% of patients without SSD met the criteria of a current anxiety or depressive disorder as assessed by the psychiatric interview. 80.0% of patients with SSD and 66.7% of patients without SSD received a recommendation for psychotherapy. CONCLUSIONS The construct validity and clinical utility of current research criteria of DSM 5 category SSD were limited in German patients with FMS.

Abstract
BACKGROUND In routine clinical practice, the subcategories of various somatoform disorders are rarely used by the primary care physicians and there is lack of data to suggest any difference in the clinical manifestations of these subcategories. AIM To compare the symptom profile, anxiety, depression, alexithymia, somato-sensory amplification and hypochondriasis of patients with persistent somatoform pain disorder with other subtypes of somatoform disorder. METHOD A total of 119 patients diagnosed with somatoform disorders according to the International Classification of Diseases-10th Revision (ICD-10) were evaluated for prevalence of somatic symptoms, anxiety, depression, alexithymia, hypochondriacal worry and somato-sensory amplification. RESULTS No significant differences were found in the prevalence of various somatic complaints between those with persistent somatoform pain disorder group and those diagnosed with other somatoform disorders. Co-morbid anxiety and depression were seen in two-thirds of the patients, but again there was no difference in the prevalence of the same between the two groups. Similarly, no significant differences were found on alexithymia, hypochondriasis and somato-sensory amplification scales between the persistent somatoform pain disorder group and the group with other somatoform disorders. CONCLUSION There are no significant differences between the various subcategories of somatoform disorders with regard to the prevalence of somatic symptoms, anxiety or depression and psychological correlates of alexithymia, hypochondriasis and somato-sensory amplification.

Abstract
OBJECTIVE In primary care populations in Western countries, high somatic symptom severity (SSS) and low quality of life (QoL) are associated with adverse psychobehavioural characteristics. This study assessed the relationship between SSS, QoL and psychobehavioural characteristics in Chinese general hospital outpatients. METHODS This multicentre cross-sectional study enrolled 404 patients from 10 outpatient departments, including Neurology, Gastroenterology, Traditional Chinese Medicine [TCM] and Psychosomatic Medicine departments, in Beijing, Shanghai, Chengdu and Kunming. A structured interview was used to assess the cognitive, affective and behavioural features associated with somatic complaints, independent of their origin. Several standard instruments were used to assess SSS, emotional distress and health-related QoL. Patients who reported low SSS (PHQ-15<10, n=203, SOM-) were compared to patients who reported high SSS (PHQ-15≥10, n=201, SOM+). RESULTS As compared to SOM- patients, SOM+ patients showed significantly more frequently adverse psychobehavioural characteristics in all questions of the interview. In hierarchical linear regression analyses adjusted for anxiety, depression, gender and medical conditions (SSS additionally for doctor visits), high SSS was significantly associated with "catastrophising" and "illness vulnerability"; low physical QoL was associated with "avoidance of physical activities" and "disuse of body parts"; low mental QoL was associated with "need for immediate medical help." CONCLUSION In accordance with the results from Western countries, high SSS was associated with negative illness and self-perception, low physical QoL with avoidance behaviour, and low mental QoL with reassurance seeking in Chinese general hospital outpatients.

Abstract
OBJECTIVE Given the prevalence and costs of somatoform disorders, it is important to identify and adequately treat these patients as early as possible. Instruments assessing experiences, perceptions, and behaviors of somatoform disorders are rare. In this study we evaluated the structure and validity of the German version of the Health Attitude Survey (HAS), a multidimensional self-report questionnaire for somatoform disorders. METHODS This cross-sectional study involved 1452 participants. The sample was randomly split for independent exploratory (EFA) and confirmatory factor analyses (CFA). Each of the two samples (n1=726; n2=726) included patients with organic vertigo and current mental disorders (somatoform and other mental disorders). Somatic symptom burden was assessed using the Patient Health Questionnaire (PHQ-15). RESULTS The CFA did not confirm the original HAS factor structure. The EFA revealed six factors. To enhance the fit of the model, we deleted two factors with the poorest reliability and items with low factor loadings. A modified and shortened version achieved good fit indices (CFI=0.92; RMSEA=0.068). It consists of 14 instead of 27 items and four scales ("dissatisfaction with care," "frustration with ill health," "high utilization of care," "excessive health worry"). HAS subscales discriminated among somatoform patients and physically ill and/or patients with a mental but not somatoform disorder, controlled for age, sex and number of (comorbid) mental diagnoses, confirming its construct validity. CONCLUSION A modified shortened version of the HAS appears to be a reliable, valid, and economical instrument for assessing facets of somatoform disorders or of the recently published DSM-5 Somatic Symptom Disorder.

Abstract
BACKGROUND Somatoform-type disorders and functional medically unexplained symptoms are extremely common in primary care settings. These disorders, however, are consistently underdiagnosed and under-recognised which precludes effective treatment. Given that somatoform symptoms are associated with high impairment, healthcare costs and both physician and patient frustration, it is critical to improve early detection. The first step in improving patient care is to identify the current barriers which obstruct successful diagnosis to enable the design of targeted interventions. We aim to conduct a systematic review to identify the possible physician-, patient- and society-related factors and other practical constraints which may impede successful diagnosis. In the process, we will also be able to recognise the differences in methodological techniques, recommend potential avenues for future research and comment on the literature in this field as a whole. METHODS/DESIGN We aim to conduct a systematic review of the relevant peer-reviewed literature published in English or German in the past 10 years in MEDLINE, EMBASE, PsycINFO and the Cochrane Database of Systematic Reviews. Additional studies may be identified from the reference lists of included studies. Title and abstract screening and data extraction from full text manuscripts will be conducted by two independent reviewers. Because we are including a combination of qualitative and quantitative studies, the review will provide a broad understanding of the current situation. Wherever possible, the method and reporting of the review will adhere to the guidelines outlined in the PRISMA statement and bias will be assessed using the Cochrane collaboration's recommendations. We envisage that data will be synthesised using a multilevel (qualitative and quantitative) approach which combines textual narrative and thematic analysis. Barriers will be categorised as modifiable or non-modifiable according to a conceptual framework. The review has been registered in an international registry of systematic reviews PROSPERO (CRD42013002540). DISCUSSION We hope that this study will provide an insight into the barriers to diagnosis of somatoform-type disorders and the results can be used to target appropriate interventions to improve care for these patients.

J Psychosom Res 2013; 75:358-61. [PMID: 24119943 DOI: 10.1016/j.jpsychores.2013.08.017] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2013] [Revised: 08/21/2013] [Accepted: 08/24/2013] [Indexed: 12/25/2022]
Abstract
OBJECTIVE To compare the predictive validity and clinical utility of DSM-IV somatoform disorders and DSM-5 Somatic Symptom Disorder (SSD) at 12-month follow-up. METHODS In a sample of psychosomatic inpatients (n=322, mean age=45.6 years (SD 10.0), 60.6% females) we prospectively investigated DSM-IV somatoform disorders and the DSM-5 diagnosis of SSD plus a variety of psychological characteristics, somatic symptom severity, and health-related quality of life at admission, discharge, and follow-up. RESULTS DSM-IV diagnoses and DSM-5 SSD similarly predicted physical functioning at follow-up; SSD also predicted mental functioning at follow-up. Bodily weakness, intolerance of bodily complaints, health habits, and somatic attribution at admission were significant predictors of physical functioning at follow-up. The change in physical functioning during inpatient therapy was a significant predictor for the course of physical functioning until follow-up. CONCLUSIONS Psychological symptoms appear to be predictively valid diagnostic criteria for the 12-month functional outcome in patients with SSD. Mental functioning can be better predicted by the DSM-5 diagnosis than by DSM-IV diagnoses. Not the change in single psychological features but in physical functioning during the treatment interval predicted the change in physical functioning until follow-up.

J Psychosom Res 2013; 75:199-210.

Abstract
OBJECTIVE Research on hypochondriasis and other somatoform disorders (SFD) has provided evidence that patients with SFD tend to attribute their symptoms to organic dysfunctions or disease. However, recent studies appear to discredit this. There is no systematic evidence on whether patients with SFD predominantly rely on somatic attributions, despite calls to include somatic attributions as a positive criterion of somatic symptom disorder (SSD) in the upcoming Diagnostic and Statistical Manual of Mental Disorders (DSM-5). METHODS This study is a systematic review of quantitative studies which assess the descriptive and predictive validity of somatic attribution in SFD. The literature search was restricted to studies with patients who met the DSM-IV criteria for SFD. RESULTS Somatic attribution style in SFD has acceptable descriptive but insufficient predictive validity. This confirms that the overlap between somatic and psychological attributions is often substantial. Attribution style can discriminate between SFD patients with and without comorbidity. CONCLUSION A somatic attribution style does not qualify as a positive criterion in SSD. However, there is an urgent need for further research on causal illness perceptions in the full spectrum of medically unexplained symptoms in order to confirm this result. Given its high prevalence, research on psychological attribution style is warranted. Re-attribution does not provide a framework sophisticated enough to address the needs of patients in primary care.

Abstract
This paper describes the rationale for the new diagnosis of somatic symptom disorder (SSD) within DSM5. SSD represents a consolidation of a number of previously listed diagnoses. It deemphasizes the centrality of medically unexplained symptoms and defines the disorder on the basis of persistent somatic symptoms associated with disproportionate thoughts, feelings, and behaviors related to these symptoms. Data are presented concerning reliability, validity, and prevalence of SSD, as well as tasks for future research, education, and clinical practice.
