Abstract
OBJECTIVE The neurobiological correlates of Somatic Symptom Disorder (SSD) introduced in the DSM-5 has been the focus of a limited investigation. We aimed to examine the cortical response to painful stimuli and its relationship to symptom severity as well as cognitive and psychological characteristics in proposed models of somatoform disorders. METHODS We measured hemodynamic responses by 52-channel functional near-infrared spectroscopy. We compared the cortical response to painful stimuli in index patients with SSD (N = 21) versus age, and gender matched healthy control subjects (N = 21). We used brush stimulation as the control condition. We analyzed the relationship of cortical activity with SSD symptom severity as well as somatosensory amplification (SSA), alexithymia, dysfunctional illness behaviour, worry, and neuroticism. RESULTS Patients with SSD had higher somatic symptom severity, SSA, alexithymia, neuroticism, illness-related worry, and behaviour. Somatic symptom severity was predicted by a model including SSA and subjective feeling of pain in the index patients. Activity in the left-angular and right-middle temporal gyri was higher in the SSD subjects than the controls during pain stimulation. Positive correlations were detected between mean pain threshold levels and left middle occipital gyrus activity, as well as between SSA-scores and right-angular gyrus activity during pain condition in the index patients with SSD. CONCLUSION We present the first evidence that representation of pain in terms of cortical activity is different in subjects with SSD than healthy controls. SSA has functional neuroanatomic correlates and predicts symptom severity in SSD and therefore is involved as a valid intermediate phenotype in SSD pathophysiology.

A retrospective observational study comparing somatosensory amplification in fibromyalgia, chronic pain, psychiatric disorders and healthy subjects. Scand J Pain 2020; 21:317-329.

Abstract
OBJECTIVES Somatosensory amplification (SA) has been described as an important feature of somatoform disorders, and an "amplifying somatic style" has been reported as a negative connotation of body perception. As widespread pain (WSP) in fibromyalgia (FM) is due to a central sensitization (CS) rather than organic alterations, there has been discussion as to whether FM is equivalent to or distinct from somatization disorder (SD). Assuming SD and FM are two distinct entities, an increase in somatic amplification should be expected only in subjects who have SD, regardless of the type of pain they experience. Purpose of the study was to explore the magnitude of SA in FM, and whether this depends on the association with SD. METHODS FM (n=159) other forms of chronic pain (OCP, n=582), psychiatric (Psy, n=53) and healthy (H, n=55) subjects were investigated using the Somatosensory Amplification Scale (SSAS), Illness Behavior Questionnaire, (IBQ), Italian Pain Questionnaire (IPQ), and Cold Pressor Test (CPT) in a retrospective observational study. RESULTS FM subjects displayed higher SSAS scores than the other groups. High SSAS score was associated with FM (OR=8.39; 95%CI: 5.43-12.46) but not OCP. Although FM has the highest prevalence of SD (x2=14.07; p=.007), high SSAS scores were associated with SD in OCP but not in FM. CONCLUSIONS Unlike in OCP, in FM high SSAS scores were independent of the presence of SD. From a biopsychosocial perspective, SSAS may be a factor associated with the onset of FM.

Abstract
Purpose To develop a clinical score to discriminate patients with somatic symptom disorder (SSD) from those with medical disease (MD) for complaints of non-acute pain. Methods We retrospectively examined the clinical records of consecutive patients with pain for a duration of ≥1 month in our department from April 2003 to March 2015. We divided the subjects according to the diagnoses of definite SSD (as diagnosed and tracked by psychiatrists in our hospital), probable SSD (without evaluation by psychiatrists in our hospital), matched MD (randomly matched two patients by age, sex, and pain location for each definite SSD patient), unmatched MD, other mental disease, or functional somatic syndrome (FSS). We investigated eight clinical factors for definite SSD and matched MD, and developed a diagnostic score to identify SSD. We subsequently validated the model with cases of probable SSD and unmatched MD. Results The number of patients with definite SSD, probable SSD, matched MD, unmatched MD, other mental disease, and FSS was 104 (3.5%), 214 (7.3%), 197 (6.7%), 742 (25%), 708 (24%), and 978 (33%), respectively. In a conditional logistic regression analysis, the following five factors were included as independent predictors of SSD: Analgesics ineffective, Mental disorder history, Unclear provocative/palliative factors, Persistence without cessation, and Stress feelings/episodes (A-MUPS). The area under the receiver operating characteristic curve (AUC) of the model was 0.900 (95% CI: 0.864–0.937, p<0.001), and the McFadden’s pseudo-R-squared was 0.709. For internal validation, the AUC between probable SSD and unmatched MD was 0.930 (95% CI: 0.910–0.950, p<0.001). The prevalence and the likelihood ratio of SSD increased as the score increased. Conclusion The A-MUPS score was useful for discriminating patients with SSD from those with MD for complaints of non-acute pain, although external validation and refinement should be needed.

Abstract
OBJECTIVE In light of interpersonal difficulties and their relation to alexithymia in patients with somatoform disorder, the primary aim of this study was to explore the association between two insecure attachment strategies (deactivation and hyperactivation strategies), and affective and cognitive alexithymia in a sample of 128 patients with severe somatoform disorder, over and above the levels of negative affectivity and personality pathology. METHOD In a cross-sectional study among patients with somatoform disorder, self-report data were obtained using measures for alexithymia (Bermond-Vorst Alexithymia Questionnaire), attachment (Experiences in Close Relationships Questionnaire), personality pathology (Inventory of Personality Organization), and negative affectivity (Dutch Short Form of the MMPI). We used hierarchical regression analyses to test main effects of attachment deactivation and hyperactivation strategies in the prediction of both cognitive and affective alexithymia, while controlling for the levels of negative affectivity and personality pathology. RESULTS Only cognitive alexithymia, i.e., the inability to analyze, identify, and verbalize emotions, was associated with personality dysfunction, in particular insecure attachment strategies. Affective alexithymia, i.e., the inability to fantasize and to experience emotions, was associated (negatively) with negative affectivity but not with the personality variables. CONCLUSIONS This study, therefore, indicates that both types of alexithymia are relevant for the assessment and treatment of severe somatoform disorder, yet each type may tap into different features of somatoform disorder.

Abstract
BACKGROUND Medically unexplained physical symptoms (MUPS) are physical symptoms for which no adequate medical explanation can be found after proper examination. The presence of MUPS is the key feature of conditions known as 'somatoform disorders'. Various psychological and physical therapies have been developed to treat somatoform disorders and MUPS. Although there are several reviews on non-pharmacological interventions for somatoform disorders and MUPS, a complete overview of the whole spectrum is missing. OBJECTIVES To assess the effects of non-pharmacological interventions for somatoform disorders (specifically somatisation disorder, undifferentiated somatoform disorder, somatoform disorders unspecified, somatoform autonomic dysfunction, pain disorder, and alternative somatoform diagnoses proposed in the literature) and MUPS in adults, in comparison with treatment as usual, waiting list controls, attention placebo, psychological placebo, enhanced or structured care, and other psychological or physical therapies. SEARCH METHODS We searched the Cochrane Depression, Anxiety and Neurosis Review Group's Specialised Register (CCDANCTR) to November 2013. This register includes relevant randomised controlled trials (RCTs) from The Cochrane Library, EMBASE, MEDLINE, and PsycINFO. We ran an additional search on the Cochrane Central Register of Controlled Trials and a cited reference search on the Web of Science. We also searched grey literature, conference proceedings, international trial registers, and relevant systematic reviews. SELECTION CRITERIA We included RCTs and cluster randomised controlled trials which involved adults primarily diagnosed with a somatoform disorder or an alternative diagnostic concept of MUPS, who were assigned to a non-pharmacological intervention compared with usual care, waiting list controls, attention or psychological placebo, enhanced care, or another psychological or physical therapy intervention, alone or in combination. DATA COLLECTION AND ANALYSIS Four review authors, working in pairs, conducted data extraction and assessment of risk of bias. We resolved disagreements through discussion or consultation with another review author. We pooled data from studies addressing the same comparison using standardised mean differences (SMD) or risk ratios (RR) and a random-effects model. Primary outcomes were severity of somatic symptoms and acceptability of treatment. MAIN RESULTS We included 21 studies with 2658 randomised participants. All studies assessed the effectiveness of some form of psychological therapy. We found no studies that included physical therapy.Fourteen studies evaluated forms of cognitive behavioural therapy (CBT); the remainder evaluated behaviour therapies, third-wave CBT (mindfulness), psychodynamic therapies, and integrative therapy. Fifteen included studies compared the studied psychological therapy with usual care or a waiting list. Five studies compared the intervention to enhanced or structured care. Only one study compared cognitive behavioural therapy with behaviour therapy.Across the 21 studies, the mean number of sessions ranged from one to 13, over a period of one day to nine months. Duration of follow-up varied between two weeks and 24 months. Participants were recruited from various healthcare settings and the open population. Duration of symptoms, reported by nine studies, was at least several years, suggesting most participants had chronic symptoms at baseline.Due to the nature of the intervention, lack of blinding of participants, therapists, and outcome assessors resulted in a high risk of bias on these items for most studies. Eleven studies (52% of studies) reported a loss to follow-up of more than 20%. For other items, most studies were at low risk of bias. Adverse events were seldom reported.For all studies comparing some form of psychological therapy with usual care or a waiting list that could be included in the meta-analysis, the psychological therapy resulted in less severe symptoms at end of treatment (SMD -0.34; 95% confidence interval (CI) -0.53 to -0.16; 10 studies, 1081 analysed participants). This effect was considered small to medium; heterogeneity was moderate and overall quality of the evidence was low. Compared with usual care, psychological therapies resulted in a 7% higher proportion of drop-outs during treatment (RR acceptability 0.93; 95% CI 0.88 to 0.99; 14 studies, 1644 participants; moderate-quality evidence). Removing one outlier study reduced the difference to 5%. Results for the subgroup of studies comparing CBT with usual care were similar to those in the whole group.Five studies (624 analysed participants) assessed symptom severity comparing some psychological therapy with enhanced care, and found no clear evidence of a difference at end of treatment (pooled SMD -0.19; 95% CI -0.43 to 0.04; considerable heterogeneity; low-quality evidence). Five studies (679 participants) showed that psychological therapies were somewhat less acceptable in terms of drop-outs than enhanced care (RR 0.93; 95% CI 0.87 to 1.00; moderate-quality evidence). AUTHORS' CONCLUSIONS When all psychological therapies included this review were combined they were superior to usual care or waiting list in terms of reduction of symptom severity, but effect sizes were small. As a single treatment, only CBT has been adequately studied to allow tentative conclusions for practice to be drawn. Compared with usual care or waiting list conditions, CBT reduced somatic symptoms, with a small effect and substantial differences in effects between CBT studies. The effects were durable within and after one year of follow-up. Compared with enhanced or structured care, psychological therapies generally were not more effective for most of the outcomes. Compared with enhanced care, CBT was not more effective. The overall quality of evidence contributing to this review was rated low to moderate.The intervention groups reported no major harms. However, as most studies did not describe adverse events as an explicit outcome measure, this result has to be interpreted with caution.An important issue was that all studies in this review included participants who were willing to receive psychological treatment. In daily practice, there is also a substantial proportion of participants not willing to accept psychological treatments for somatoform disorders or MUPS. It is unclear how large this group is and how this influences the relevance of CBT in clinical practice.The number of studies investigating various treatment modalities (other than CBT) needs to be increased; this is especially relevant for studies concerning physical therapies. Future studies should include participants from a variety of age groups; they should also make efforts to blind outcome assessors and to conduct follow-up assessments until at least one year after the end of treatment.

Abstract
Intolerance of uncertainty (IU)--a multidimensional cognitive vulnerability factor--is associated with a variety of anxiety disorders and health anxiety (HA). To date, few studies have assessed whether IU dimensions (prospective and inhibitory IU) are differentially associated with HA and whether their contributions are independent of anxiety sensitivity (AS). This study addressed these issues using independent community (n = 155; 81% women) and undergraduate (n = 560; 86% women) samples. Results indicated that prospective IU, but not inhibitory IU, had significant positive associations with HA in community dwellers and undergraduate students. AS somatic and cognitive concerns were also significant predictors among both samples. In addition, severity of IU dimensions among individuals reporting elevated HA were compared against individuals diagnosed with generalized anxiety disorder, social anxiety disorder, panic disorder, and obsessive-compulsive disorder. Results indicated minimal differences between those with elevated HA and each of the anxiety disorder diagnoses. Findings lend support to the unique transdiagnostic nature of IU and support commonalities between HA and anxiety disorders.

Abstract
OBJECTIVE To explore patterns of experienced stress and stress reactions before the onset of illness in the life history of patients with severe somatoform disorders to identify predisposing stress-mechanisms. METHODS A systematic, thematic analysis was conducted on data collected from 24 semi-structured individual life history interviews. RESULTS Generally, patients had experienced high psychosocial stress during childhood/youth. However, there was considerable variability. Characteristic of all patients were narrations of how communication with significant adults about problems, concerns, and emotions related to stress were experienced to be difficult. The patients described how this involved conflicts stemming from perceived absent, insufficient, or dismissive communication during interactions with significant adults. We conceptualized this empirically based core theme as "emotional avoidance culture." Further, three related subthemes were identified: Generally, patients 1.) experienced difficulties communicating problems, concerns, and related complex feelings in close social relations; 2.) adapted their emotional reactions and communication to an emotional avoidance culture, suppressing their needs, vulnerability and feelings of sadness and anger that were not recognized by significant adults; and 3.) disconnected their stress reaction awareness from stressful bodily sensations by using avoidant behaviors e.g. by being highly active. CONCLUSION Patients adapted to an emotional avoidance culture characterized by difficult and conflicting communication of concerns and related emotions in social interactions with significant adults. Patients experienced low ability to identify and express stress-related cognitions, emotions and feelings, and low bodily and emotional self-contact, which made them vulnerable to stressors. Generally, patients resolved stress by avoidant behaviors, prolonging their stress experience.

Abstract
The Diagnostic Criteria for Psychosomatic Research (DCPR) were introduced in 1995 by an international group of investigators to expand the traditional domains of the disease model. The DCPR are a set of 12 'psychosomatic syndromes' which provide operational tools for psychosocial variables with prognostic and therapeutic implications in clinical settings. Eight syndromes concern the main manifestations of abnormal illness behaviour: somatization, hypochondriacal fears and beliefs, and illness denial. The other four syndromes (alexithymia, type A behaviour, demoralization and irritable mood) refer to the domain of psychological factors affecting medical conditions. This review describes the conceptual bases of the DCPR and the main findings concerning their application, with particular reference to the incremental information they added to the customary psychiatric classification. The DCPR were also compared with the provisional DSM-5 somatic symptom disorders. The DCPR were found to be more sensitive than DSM-IV in identifying subthreshold psychological distress and characterizing patients' psychological response to medical illness. DSM-5 somatic symptom disorders seem to neglect important clinical phenomena, such as illness denial, resulting in a narrow view of patients' functioning. The additional information provided by the DCPR may enhance the decision-making process.

Abstract
Somatoform pain is a highly prevalent, debilitating condition and a tremendous public health problem. Effective treatments for somatoform pain are urgently needed. The etiology of this condition is, however, still unknown. On the basis of a review of recent basic and clinical research, we propose one potential mechanism of symptom formation in somatoform pain and a developmental theory of its pathogenesis. Emerging evidence from animal and human studies in developmental neurobiology, cognitive-affective neuroscience, psychoneuroimmunology, genetics, and epigenetics, as well as that from clinical and treatment studies on somatoform pain, points to the existence of a shared neural system that underlies physical and social pain. Research findings also show that nonoptimal early experiences interact with genetic predispositions to influence the development of this shared system and the ability to regulate it effectively. Interpersonal affect regulation between infant and caregiver is crucial for the optimal development of these brain circuits. The aberrant development of this shared neural system during infancy, childhood, and adolescence may therefore ultimately lead to an increased sensitivity to physical and social pain and to problems with their regulation in adulthood. The authors critically review translational research findings that support this theory and discuss its clinical and research implications. Specifically, the proposed theory and research review suggest that psychotherapeutic and/or pharmacological interventions that foster the development of affect regulation capacities in an interpersonal context will also serve to more effectively modulate aberrantly activated neural pain circuits and thus be of particular benefit for the treatment of somatoform pain.

Abstract
The etiopathology of somatoform disorders can only be understood against the background of an integrated biopsychosocial model. Cultural and historical influences must be taken into account as well as contemporary settings of scientific or medical priorities. In this context the emphasis on neurobiological findings can be interpreted as the non-accidental struggle for legitimacy of both patients and physicians. Altogether the available data on factors influencing the formation and maintenance of somatoform symptoms has to be described as both diverse and unspecific and thus points to a challenging research program in the coming years.

Abstract
Many patients with somatoform disorders present to the neurology clinic, often after extensive evaluation that has left the patient and multiple other physicians frustrated. Knowledge of the typical characteristics of particular disorders enables the clinician to arrive at a positive diagnosis and facilitate referral to appropriate services. Using a series of representative cases, we review the DSM-IV-TR somatoform disorders most likely to present to the practicing neurologist, highlighting the epidemiologic features, typical presentations, and possible therapeutic approaches to each condition.

Abstract
There is a wide debate among the researchers and clinicians over the diagnostic categories subsumed under the rubric of somatoform disorders (SDs). Recent proposals vary from radical views that call for removing this category altogether to the conservative views that suggests cosmetic changes in the diagnostic criteria of SDs. We have the reviewed the relevant literature through PUBMED search supplemented with manual search on current concepts of SD.

Abstract
OBJECTIVE Somatoform disorders are common conditions, but the current diagnostic criteria are considered to be unreliable, based largely on medically unexplained symptoms. DSM-5 is considering other possible characteristics of somatizers including high utilization, dissatisfaction with care, and poor response to reassurance. This paper reviews the available literature for evidence to support these criteria, and evaluates if distinctive aspects of these characteristics exist in somatizers. METHODS The Pubmed database was searched combining terms such as “somatoform disorder” with “reassurance,” “satisfaction,” and “utilization.” Articles were individually inspected. RESULTS Many studies report a deficit in long-term response to reassurance in somatizers; there was some evidence that patients respond initially to reassurance, followed by return of anxiety, leading to further reassurance seeking. There was insufficient evidence to support poor satisfaction with care as a characteristic of somatizers. While there is no standard criterion for high utilization, regardless of definition, evidence was found to support over-utilization, particularly in outpatient visits. However, no unique pattern of utilization was found that could identify somatizers within a broader group of high utilizers. CONCLUSIONS This review revealed evidence of over-utilization in many areas of healthcare, as well as poor long term response to reassurance in somatizers. Dissatisfaction with care, though, was not a consistent finding. It is difficult to study alternative diagnostic criteria for somatoform patients when the current criteria rest on so many problematic assumptions. Future research should attempt to validate criteria empirically in patient groups, with selection not based on medically unexplained symptoms.

Abstract
OBJECTIVE Somatic causal illness attributions are being considered as potential positive criteria for somatoform disorders (SFDs) in DSM-V. The aim of this study was to investigate whether patients diagnosed with SFDs tend towards a predominantly somatic attribution style. METHODS We compared the causal illness attributions of 48 SFD and 149 non-somatoform disorder patients, in a sample of patients presenting for an allergy diagnostic work-up, and those of 47 controls hospitalised for allergen-specific venom immunotherapy. The SFD diagnosis was established by means of the Structured Clinical Interview for DSM-IV. Both spontaneous and prompted causal illness attributions were recorded through interview and by means of the causal dimension of the Revised Illness Perception Questionnaire (IPQ-R), respectively. Patients' spontaneous and prompted responses were assigned to a psychosocial, somatic, or mixed attribution style. RESULTS Both in the free-response task and in their responses to the IPQ-R, SFD patients were no more likely than their nonsomatoform counterparts to focus on somatic explanations for their symptoms. They were just as likely to make psychosocial or mixed causal attributions. However, patients with SFDs were significantly more likely to find fault with medical care in the past. CONCLUSION Our data do not support the use of somatic causal illness attributions as positive criteria for SFDs. They confirm the dynamic and multidimensional nature of causal illness attributions. Clinical implications of these findings are discussed.

Abstract
BACKGROUND In order to reconceptualize somatoform disorders (SFDs), the psychological characteristics of SFD patients are increasingly investigated. The cognitive style of magical thinking (MT) has not been studied so far in patients with SFDs. SAMPLING AND METHODS In a cross-sectional study, 201 allergy workup patients were interviewed using the Structured Clinical Interview for DSM-IV; they answered a set of self-report questionnaires including the Schizotypal Personality Questionnaire subscale for MT and the Patient Health Questionnaire (PHQ). The expression of MT was explored in 61 patients with SFDs compared to 140 patients without SFDs. RESULTS Patients with SFDs reached higher scores of MT, also when controlled for gender, depression, and anxiety. In particular, they stated more frequently that they were believers in telepathy (64 vs. 44%) and clairvoyance (43 vs. 16%). MT correlated only weakly with somatization/somatic symptom severity, depression, and anxiety. CONCLUSIONS Among allergy workup patients with SFDs we found considerable MT. This indicates that SFD patients may tend to mistake correlation for causality in a more general way, and not just in an illness-related context. The relation to indicators of illness severity (somatic symptom severity/somatization, depression, and anxiety) was relatively weak. Possible implications for research, diagnostics, and therapy are discussed.

Abstract
Since the 20th century, psychogenic female sexual dysfunctions (FSD), like some somatoform and conversion disorders, have been considered an expression of somatoform dissociation. Several studies have reported dissociative symptoms in different somatoform and conversion disorders, but limited data are available on dissociation among patients with FSD. The aim of this study was to assess somatoform and psychoform dissociation among patients with women's orgasmic disorder, dyspareunia, and vaginismus. A battery of self-administered questionnaires (Somatoform Dissociation Questionnaire, Dissociative Experiences Scale, Hospital Anxiety and Depression Scale, Impact of Event Scale-Revised) was given to 200 gynecological outpatients to assess psychoform and somatoform dissociation and their association with FSD. A strong association between somatoform dissociation and FSD was observed (adjusted odds ratio [OR] = 5.39, 95% confidence interval [CI] = 1.15-25.32), the association between somatoform and psychoform dissociation being estimated by an adjusted OR of 4.83 (95% CI = 1.17-19.91). Our results are compatible with the idea that some forms of FSD could be regarded as somatoform dissociative disorders.

Abstract
PURPOSE The current study examined the prevalence and correlates of somatic distress (SD) in the aftermath of war, and the role of a process hypothesized to contribute to posttraumatic stress: experiential avoidance. METHODS Civilian war survivors (n = 163) from Kosovo were assessed in structured interviews, reporting on average more than ten types of traumatic war exposure. RESULTS One in eight (12.9%) of the participants meet criteria for SD, which was associated with greater psychological distress, experiential avoidance, and lower quality of life after accounting for the effects of war-related variables, demographic variables, as well as posttraumatic stress disorder and major depressive episode. Experiential avoidance partially mediated the association between SD and psychological distress and quality of life. CONCLUSIONS The results indicate that SD is prevalent among war-exposed civilians and that experiential avoidance may be a significant factor in understanding and treating traumatized people who are experiencing SD.

Abstract
OBJECTIVE To evaluate psychological characteristics that could be used for the classification of somatic syndromes requesting medical care. Positive psychological classification criteria are needed to justify the classification of somatic syndromes as Diagnostic and Statistical Manual of Mental Disorders- or International Classification of Diseases-10 section F/mental disorders diagnosis. METHODS From a population-based sample of 2510 people, subsamples reporting high scores for somatic symptoms (SOM+; n = 154) versus average scores for somatic symptoms (SOM-; n = 167) were defined. Telephone interviews (e.g., structured interviews for diagnoses, healthcare use, symptom history, possible psychological characteristics), self-rating scales (e.g., Pain Disability Index, depression scale Patient Health Questionnaire-9), and general practitioners reports were collected for these subsamples. In addition to somatic symptoms, we used healthcare use and disability as major external validation criteria. RESULTS There was strong evidence for ten of the 28 binary coded psychological variables to identify those people with somatic symptoms who needed medical help and/or were seriously disabled. These variables included "avoidance of physical activities," "bias for somatic illness attributions," "self-concept of being physically weak," and "desperation because of somatic symptoms." The relevance of these psychological characteristics was partially further confirmed by stepwise regression analyses, which showed incremental validity compared with variables like somatic symptoms and depression. CONCLUSIONS This study identified several psychological characteristics of people with somatic complaints who need medical care. These features can be assessed, using binary variables that are more feasible for classification processes. These psychological criteria should be included in classification rules for people with somatic syndromes (e.g., somatoform disorders).

Abstract
OBJECTIVE (i) To analyze general practitioners' diagnosis of somatisation disorder (P75) using the International Classification of Primary Care (ICPC)-2-E in routine general practice. (ii) To validate the distinctiveness of the ICD-10 to ICPC-2 conversion rule which maps ICD-10 dissociative/conversion disorder (F44) as well as half of the somatoform categories (F45.0-2) to P75 and codes the other half of these disorders (F45.3-9), including autonomic organ dysfunctions and pain syndromes, as symptom diagnoses plus a psychosocial code in a multiaxial manner. METHODS Cross-sectional analysis of routine data from a German research database comprising the electronic patient records of 32 general practitioners from 22 practices. For each P75 patient, control subjects matched for age, gender, and practice were selected from the 2007 yearly contact group (YCG) without a P75 diagnosis using a propensity-score algorithm that resulted in eight controls per P75 patient. RESULTS Of the 49,423 patients in the YCG, P75 was diagnosed in 0.6% (302) and F45.3-9 in 1.8% (883) of cases; overall, somatisation syndromes were diagnosed in 2.4% of patients. The P75 coding pattern coincided with typical characteristics of severe, persistent medically unexplained symptoms (MUS). F45.3-9 was found to indicate moderate MUS that otherwise showed little clinical difference from P75. Pain syndromes exhibited an unspecific coding pattern. Mild and moderate MUS were predominantly recorded as symptom diagnoses. Psychosocial codes were rarely documented. CONCLUSIONS ICPC-2 P75 was mainly diagnosed in cases of severe MUS. Multiaxial coding appears to be too complicated for routine primary care. Instead of splitting P75 and F45.3-9 diagnoses, it is proposed that the whole MUS spectrum should be conceptualized as a continuum model comprising categorizations of uncomplicated (mild) and complicated (moderate and severe) courses. Psychosocial factors require more attention.

Abstract
OBJECTIVE Psychobehavioral characteristics of patients with somatoform disorders (SFDs), are increasingly discussed as possible positive criteria for this diagnostic group. However, little is known about psychobehavioral differences, or similarities, between the different SFD presentations, i.e., polysymptomatic [multisomatoform/somatization disorders (MSD)] versus mono- or oligosymptomatic courses [pain disorder (PD), undifferentiated somatoform disorder (USD)]. METHODS This is a cross-sectional study including 268 consecutive allergology inpatients. After an Structured Clinical Interview for DSM-IV, patients completed several self-rating questionnaires. Results were compared within the different SFD presentations as well as between patients with versus without SFDs. RESULTS We identified 72 patients with an SFD. There were fewer and smaller psychobehavioral differences within patients with the different SFD presentations (MSD, USDs, PDs) than between patients with undifferentiated versus no SFD. Patients with one of the three different SFD subdiagnoses scored similarly on many measures referring to psychosocial distress (e.g., psychological distress, mental health-related quality of life, dissatisfaction with care). The number of reported symptoms, somatic symptom severity, a self-concept of bodily weakness, the degree of disease conviction, and physical health-related quality of life discriminated the different SFD presentations not only from patients without SFDs but also from each other. CONCLUSIONS Patients diagnosed with one of the different SFD subtypes share many psychobehavioral characteristics, mostly regarding the reporting of psychosocial distress. Perceived somatic symptom severity and physical impairment as indicators of bodily distress could either further define categorical subdivisions of SFD or dimensionally graduate one general SFD category defined by bothering bodily symptoms and disproportionate psychosocial distress.

Abstract
OBJECTIVES The classification of somatoform disorders is currently being revised in order to improve its validity for the DSM-V and ICD-11. In this article, we compare the validity and clinical utility of current and several new diagnostic proposals of those somatoform disorders that focus on medically unexplained somatic symptoms. METHODS We searched the Medline, PsycInfo, and Cochrane databases, as well as relevant reference lists. We included review papers and original articles on the subject of somatoform classification in general, subtypes of validity of the diagnoses, or single diagnostic criteria. RESULTS Of all diagnostic proposals, only complex somatic symptom disorder and the Conceptual Issues in Somatoform and Similar Disorders (CISSD) example criteria reflect all dimensions of current biopsychosocial models of somatization (construct validity) and go beyond somatic symptom counts by including psychological and behavioral symptoms that are specific to somatization (descriptive validity). Predictive validity of most of the diagnostic proposals has not yet been investigated. However, the number of somatic symptoms has been found to be a strong predictor of disability. Some evidence indicates that psychological symptoms can predict disease course and treatment outcome (e.g., therapeutic modification of catastrophizing is associated with positive outcome). Lengthy symptom lists, the requirement of lifetime symptom report (as in abridged somatization), complicated symptom patterns (as in current somatization disorder), and imprecise definitions of diagnostic procedures (e.g., missing symptom threshold in complex somatic symptom disorder) reduce clinical utility. CONCLUSION Results from the reviewed studies suggest that, of all current and new diagnostic suggestions, complex somatic symptom disorder and the CISSD definition appear to have advantages regarding validity and clinical utility. The integration of psychological and behavioral criteria could enhance construct and descriptive validity, and confers prospectively relevant treatment implications. The incorporation of a dimensional approach that reflects both somatic and psychological symptom severity also has the potential to improve predictive validity and clinical utility.

Abstract
OBJECTIVE To explore a combination of health-related psychobehavioral features as potential positive criteria for somatoform disorders (SFD). Currently, SFD can only be diagnosed in the absence of sufficient organic symptom explanation, resulting in low criterion validity and delay of appropriate therapy. METHODS Cross sectionally, we studied various psychobehavioral characteristics of 197 inpatients with suspected allergies. At the beginning of the medical work-up, patients were interviewed and completed a set of self-rating questionnaires (Illness Perception Questionnaire-Revised, Whiteley Index-7, Cognitions About Body And Health Questionnaire, Scale for the Assessment of Illness Questionnaire, Health Attitude Survey, Reassurance Questionnaire, and Patient Health Questionnaire). Organic explicability of the presenting symptoms was assessed by allergists at the end of the work-up. Forty-eight patients with SFD were compared with 149 patients without SFD, and predictive models were set up. To control for effects of the work-up situation, we also investigated 47 patients with an established diagnosis of hymenoptera venom allergy. RESULTS In the work-up group, various self-reported psychobehavioral features discriminated patients with SFD from patients without SFD. In logistic regression analysis, self-reported dissatisfaction with medical care, disease conviction, reduced symptom controllability, and reduced body scanning independently predicted SFD. A predictive model based on these psychobehavioral characteristics had high sensitivity and specificity (area under the curve = 0.86, 95% Confidence Interval = 0.79-0.93; p < .001), which was comparable to the Patient Health Questionnaire-15, an established SFD screening tool assessing somatization. CONCLUSIONS Psychobehavioral characteristics in patients with SFD cannot solely be attributed to the uncertainty of a work-up situation. Their predictive value is comparable to that of the traditional measuring of symptom number and severity; hence, they should be considered as SFD positive criteria in Diagnostic and Statistic Manual of Mental Disorders, 5th Edition.

Abstract
Chronic pain requires comprehensive care. While interdisciplinary approaches are recommended, the role of psychiatrists is often misunderstood. Psychiatrists should be involved with the care of patients with chronic pain as early as possible to maximize outcome. Psychiatrists offer an expertise that specifically addresses important deficiencies in the care of patients with chronic pain: 1) the lack of a detailed formulation, 2) the lumping of all psychopathology, and 3) the failure to effectively use psychopharmacologic treatments. This review provides a framework for formulating the diagnoses and treatments of patients with chronic pain.

Abstract
Somatization disorder is a somatoform disorder that overlaps with a number of functional somatic syndromes and has high comorbidity with major depression and anxiety disorders. Proposals have been made for revising the category of somatoform disorders, for simplifying the criteria for somatization disorder, and for emphasizing the unitary nature of the functional somatic syndromes in future classifications. A review of the cognitive-affective neuroscience of somatization disorder and related conditions suggests that overlapping psychobiological mechanisms mediate depression, anxiety, and somatization symptoms. Particular genes and environments may contribute to determining whether symptoms are predominantly depressive, anxious, or somatic, and there are perhaps also overlaps and distinctions in the distal evolutionary mechanisms that produce these symptoms.
