A systematic review. J Psychosom Res 2009; 66:363-77. [PMID: 19379952 DOI: 10.1016/j.jpsychores.2008.09.018] [Citation(s) in RCA: 172] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2008] [Revised: 09/22/2008] [Accepted: 09/23/2008] [Indexed: 12/19/2022]
Abstract
OBJECTIVE To study the course of medically unexplained symptoms (MUS), somatisation disorder, and hypochondriasis, and related prognostic factors. Knowledge of prognostic factors in patients presenting persistent MUS might improve our understanding of the naturalistic course and the identification of patients with a high risk of a chronic course. METHODS A comprehensive search of Medline, PsycInfo, CINAHL, and EMBASE was performed to select studies focusing on patients with MUS, somatisation disorder, and hypochondriasis, and assessing prognostic factors. Studies focusing on patients with single-symptom unexplained disorder or distinctive functional somatic syndromes were excluded. A best-evidence synthesis for the interpretation of results was used. RESULTS Only six studies on MUS, six studies on hypochondriasis, and one study on abridged somatisation could be included. Approximately 50% to 75% of the patients with MUS improve, whereas 10% to 30% of patients with MUS deteriorate. In patients with hypochondriasis, recovery rates vary between 30% and 50%. In studies on MUS and hypochondriasis, we found some evidence that the number of somatic symptoms at baseline influences the course of these conditions. Furthermore, the seriousness of the condition at baseline seemed to influence the prognosis. Comorbid anxiety and depression do not seem to predict the course of hypochondriasis. CONCLUSIONS Due to the limited numbers of studies and their high heterogeneity, there is a lack of rigorous empirical evidence to identify relevant prognostic factors in patients presenting persistent MUS. However, it seems that a more serious condition at baseline is associated with a worse outcome.

Somatization increases disability independent of comorbidity. J Gen Intern Med 2009; 24:155-61. [PMID: 19031038 PMCID: PMC2629001 DOI: 10.1007/s11606-008-0845-0] [Citation(s) in RCA: 60] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2008] [Revised: 10/02/2008] [Accepted: 10/08/2008] [Indexed: 10/21/2022]
Abstract
BACKGROUND Somatoform disorders are an important factor in functional disability and role impairment, though their independent contribution to disability has been unclear because of prevalent medical and psychiatric comorbidity. OBJECTIVES To assess the extent of the overlap of somatization with other psychiatric disorders and medical problems, to compare the functional disability and role impairment of somatizing and non-somatizing patients, and to determine the independent contribution of somatization to functional disability and role impairment. DESIGN Patients were surveyed with self-report questionnaires assessing somatization, psychiatric disorder, and role impairment. Medical morbidity was indexed with a computerized medical record audit. PARTICIPANTS Consecutive adults making scheduled visits to their primary care physicians at two hospital-affiliated primary care practices on randomly chosen days. MEASUREMENTS Intermediate activities of daily living, social activities, and occupational disability. RESULTS Patients with somatization, as well as those with serious medical and psychiatric illnesses, had significantly more impairment of activities of daily life and social activities. When these predictors were considered simultaneously in a multivariable regression, the association with somatization remained highly significant and was comparable to or greater than many major medical conditions. CONCLUSIONS Patients with somatization had substantially greater functional disability and role impairment than non-somatizing patients. The degree of disability was equal to or greater than that associated with many major, chronic medical disorders. Adjusting the results for psychiatric and medical co-morbidity had little effect on these findings.

Abstract
OBJECTIVE Pathological gambling is proposed as a participant of an impulsive-compulsive spectrum related to obsessive-compulsive disorder. This study aims to contrast pathological gambling and obsessive-compulsive disorder regarding course, comorbidity, and personality, hence testing the validity of the impulsive-compulsive spectrum. METHOD 40 pathological gambling and 40 obsessive-compulsive disorder subjects matched to 40 healthy volunteers according to gender, age, and education were assessed with the Temperament Personality Questionnaire and the Barratt Impulsiveness Scale. Psychiatric patients were also assessed for course and comorbidity data. RESULTS Obsessive-compulsive disorder presented an earlier onset, but the full syndrome took longer to evolve. Pathological gambling had higher comorbidity with substance-related disorders, and obsessive-compulsive disorder higher comorbidity with somatoform disorders. Gamblers scored higher than controls on the sub-factors Impulsiveness, Extravagance, Disorderliness, and Fear of Uncertainty. Obsessive-compulsive patients scored higher than controls on Fear of Uncertainty. Impulsiveness, Extravagance, and Disorderliness significantly correlated with the Barratt Impulsiveness Scale total score, Fear of Uncertainty did not. DISCUSSION The course and comorbidity profiles of pathological gambling resemble an addiction and differ from obsessive-compulsive disorder. Pathological gambling combines impulsive and compulsive traits. Impulsivity and compulsivity should be regarded as orthogonal constructs, and as drives implicated in volition aspects of behavioral syndromes.

Abstract
BACKGROUND Hypochondriasis is associated with significant medical morbidity and high health resource use. Recent studies have examined the treatment of hypochondriasis using various forms of psychotherapy. OBJECTIVES To examine the effectiveness and comparative effectiveness of any form of psychotherapy for the treatment of hypochondriasis. SEARCH STRATEGY 1. CCDANCTR-Studies and CCDANCTR-References were searched on 7/8/2007, CENTRAL, Medline, PsycINFO, EMBASE, Cinahl, ISI Web of Knowledge, AMED and WorldCat Dissertations; Current Controlled Trials meta-register (mRCT), CenterWatch, NHS National Research Register and clinicaltrials.gov; 2. Communication with authors of relevant studies and other clinicians in the field; 3. Handsearching reference lists of included studies and relevant review articles, and electronic citation search in ISI Web of Knowledge for all included studies. SELECTION CRITERIA All randomised controlled studies, both published and unpublished, in any language, in which adults with hypochondriasis were treated with a psychological intervention. DATA COLLECTION AND ANALYSIS Data were extracted independently by two authors using a standardised extraction sheet. Study quality was assessed independently by the two authors qualitatively and using a standardised scale. Meta-analyses were performed using RevMan software. Standardised or weighted mean differences were used to pool data for continuous outcomes and odds ratios were used to pool data for dichotomous outcomes, together with 95% confidence intervals. MAIN RESULTS Six studies were included, with a total of 440 participants. The interventions examined were cognitive therapy (CT), behavioural therapy (BT), cognitive behavioural therapy (CBT), behavioural stress management (BSM) and psychoeducation. All forms of psychotherapy except psychoeducation showed a significant improvement in hypochondriacal symptoms compared to waiting list control (SMD (random) [95% CI] = -0.86 [-1.25 to -0.46]). For some therapies, significant improvements were found in the secondary outcomes of general functioning (CBT), resource use (psychoeducation), anxiety (CT, BSM), depression (CT, BSM) and physical symptoms (CBT). These secondary outcome findings were based on smaller numbers of participants and there was significant heterogeneity between studies. AUTHORS' CONCLUSIONS Cognitive therapy, behavioural therapy, cognitive behavioural therapy and behavioural stress management are effective in reducing symptoms of hypochondriasis. However, studies included in the review used small numbers of participants and do not allow estimation of effect size, comparison between different types of psychotherapy or whether people are "cured". Most long-term outcome data were uncontrolled. Further studies should make use of validated rating scales, assess treatment acceptability and effect on resource use, and determine the active ingredients and nonspecific factors that are important in psychotherapy for hypochondriasis.

Abstract
The DSM category of "psychological factors affecting medical condition" had virtually no impact on clinical practice. However, several clinically relevant psychosomatic syndromes have been described in the literature: disease phobia, persistent somatization, conversion symptoms, illness denial, demoralization, and irritable mood. These syndromes, in addition to the DSM definition of hypochondriasis, can yield clinical specification in the category of "psychological factors affecting medical condition" and eliminate the need for the highly criticized DSM classification of somatoform disorders. This new classification is supported by a growing body of research evidence and is in line with psychosomatic medicine as a recognized subspecialty.

Abstract
A valid classification is important for further understanding of the somatoform disorders. The main disorders in this grouping - somatization disorder and hypochondriasis - have lengthy historical traditions and are defined in a contrasting manner. Various authors point to distinguishing demographic and clinical features, but there have been few direct comparisons of patients with these disorders. A review of the literature indicates those domains where differences are most likely to be found. Research assessing these may serve to refine and validate these key somatoform categories and/or dimensions.

Abstract
OBJECTIVE The objectives of this study were (a) to elucidate the methodological problems arising when examining lifetime symptom data by exploring the accuracy of recall of medically unexplained symptoms (MUS) and medically explained symptoms (MES) in the general population, based on interviews using the Composite International Diagnostic Interview (CIDI) Somatoform Section C, in 1990 and 2001, and (b) to find predictors for failure at follow-up to recall symptoms reported previously at baseline (i.e., symptoms "lost"). METHODS Four hundred twenty-one persons (response rate, 69.6%; 242 women and 179 men) were reinterviewed in 2001 from a baseline population of 605. Thirty-eight clinically significant MUS and MES were assessed. Linear multiple regression analyses with the numbers of MUS-lost (medically unexplained symptoms lost to recall) and MES-lost (medically explained symptoms lost to recall) as dependent variables were undertaken to find factors affecting symptom loss. RESULTS A wide range of individual symptoms (22-100%) were lost to recall at follow-up, indicating a large degree of measurement error, mainly due to faulty recall. The number of symptoms recalled when they were grouped was better (approximately 50% for "1-3" symptoms). Recall variability and MUS/MES transition over time undermined the credibility of this distinction. Gender and age emerged as significant (P<.01) predictors for MUS-lost, and a decrease in physical morbidity for MES-lost. Men tended to forget more symptoms than women, and younger respondents with high levels of baseline MUS remembered slightly better at follow-up. CONCLUSION Lifetime symptom data elicited in community surveys by such instruments as the CIDI should be viewed with caution. Methodological errors weakening data credibility could lead to false impressions of true change over time. A MUS/MES distinction is difficult to maintain.

Abstract
OBJECTIVE To explore critically whether there is a robust basis for the concept of an obsessive-compulsive (OC) spectrum of disorders, and if so, which disorders should be included. METHOD Selective literature review concentrating on three proposed members of the OC spectrum, namely body dysmorphic disorder, hypochondriasis and trichotillomania. RESULTS Obsessive-compulsive disorder (OCD) itself is a heterogeneous condition or group of conditions, and this needs to be appreciated in any articulation of a 'spectrum' of OC disorders. The basis for 'membership' of the spectrum is inconsistent and varied, with varying level of support for inclusion in the putative spectrum. CONCLUSION A more fruitful approach may be to consider behaviours and dimensions in OCD and OC spectrum disorders, and that this should be encompassed in further developments of the OC spectrum model.

Abstract
OBJECTIVE The Whiteley Index (WI) is a widely used instrument for measuring hypochondriacal worries and beliefs. Several studies explored the structural validity of the WI obtaining contrary results concerning the number of factors as well as the item composition. The main aim of this study is to compare factor solutions from previous studies to draw conclusions about the most valid scale model of the WI for administration in primary care. METHODS Weighted least squares (WLS) confirmatory factor analyses of the WI were conducted. The sample in study consisted of 1800 patients from primary care practices. Seven different models were compared, including single- and three-factor conceptualisations. RESULTS A seven-item, single-factor model best described the data, while three-factor models were clearly inadequate. CONCLUSIONS Results support a one-dimensional conceptualisation of the WI and suggest a certain subscale of the WI, the WI-7, to constitute the most psychometrically sound scale for use as a screening instrument for hypochondriasis in primary care. In addition to psychometric considerations, the brevity and simplicity of the WI-7 also make it attractive as a screening tool in the context of primary care. A cutoff score of 2/3, calculated on the basis of general practitioners' diagnoses, yielded the best balance of sensitivity and specificity in the present study.

Abstract
BACKGROUND Hypochondriasis (HC) involves preoccupation with fears of having a serious illness. The preoccupation is persistent and based on misinterpretation of benign bodily sensations. In response, patients often resort to frequent checks with doctors, of their own body, and of medical references, to reassure themselves of their health status. Some authors have likened HC to obsessive-compulsive disorder (OCD) on the basis of similarities between obsessions and illness preoccupation and the ritualistic checking behavior observed in each condition. METHODS In this article, the phenomenology of HC is discussed in terms of factors that account for the development and persistence of this disorder. Treatment that is derived from this conceptual model is also described. RESULTS HC is best considered as an anxiety problem in which pathological fear is focused on innocuous bodily sensations and other health-relevant cues. CONCLUSIONS Many of the psychological mechanisms of HC are similar to those present in OCD.

Abstract
Hypochondriasis was once considered treatment resistant. Recent studies, however, suggest that several interventions can be effective. This article presents a narrative review of psychosocial and pharmacologic treatments for hypochondriasis, supplemented by a meta-analysis of treatments to identify the most promising interventions. Findings suggest that cognitive behavior therapy is the most effective treatment for hypochondriasis. Fluoxetine also is promising, although the long-term effects of this and other medications remain to be examined. Psychoeducation appears to be sufficient for mild hypochondriasis. Future research on the mechanisms of hypochondriasis may shed light on how we can improve treatments, particularly for severe cases, which are least likely to benefit from psychosocial and drug interventions.

Abstract
Specific phobia of illness makes its appearance in DSM-IV as a new diagnostic subtype, separate from hypochondriasis. A review of the literature indicates that, while there is some support for this new category, studies have not as yet been done that could provide validation. Illness phobia appears to be a significant problem; it is prevalent in the general population and is associated with distress and impairment, including interference with medical care. It appears to be associated with older age, physical illness, and female gender. Group comparisons are needed showing that persons with this phobia can be distinguished from hypochondriasis on the basis of these and other demographic and illness features. We outline a research agenda for demonstrating this separation.

Abstract
BACKGROUND This paper reviews current knowledge regarding the prevalence and associated features of somatisation disorder and hypochondriasis in population-based and primary care samples. METHOD A systematic review of the literature, which used a standardised definition of somatisation disorder or hypochondriasis and which examined the characteristics and associated features of these disorders in population-based samples or primary care settings. RESULTS In population-based studies the prevalence of somatisation disorder and hypochondriasis was too low to examine associated features reliably. In studies using abridged criteria, a clear female predominance was not found in either disorder; there was a consistent relationship with few years of education. There was a close relationship with anxiety and depressive disorders, with a linear relationship between numbers of somatic and other symptoms of distress in several studies, including longitudinal studies. No studies showed that these symptom clusters fulfil the criteria of characteristic onset, course and prognosis required to merit the status of discrete psychiatric disorders. CONCLUSIONS On existing evidence, somatisation disorder and hypochondriasis cannot be regarded as definite psychiatric disorders. There is some evidence that numerous somatic symptoms or illness worry may be associated with impairment and high health care utilisation in a way that cannot be solely explained by concurrent anxiety and depression, but further research using population-based samples is required.

Abstract
Zusammenfassung. Der Whiteley-Index ist ein Instrument zur Erfassung von Hypochondrie. Für diesen Fragebogen wurde eine Normierungs- und Validierungsstudie anhand einer bevölkerungsrepräsentativen Stichprobe (n = 1996) durchgeführt. Hypochondrie zeigt eine etwa lineare Altersabhängigkeit (r = .24). Frauen haben in allen Altersstufen höhere Hypochondrie-Ausprägungen als Männer. Für verschiedene Alters- und Geschlechtsgruppen werden Normwerte bereit gestellt. Die in der Literatur beschriebene dreidimensionale Struktur des Whiteley-Index (Krankheitsängste, somatische Beschwerden und Krankheitsüberzeugung) konnte mit gewissen Einschränkungen bestätigt werden. Validierungsuntersuchungen mit anderen Instrumenten (Hospital Anxiety and Depression Scale, Multidimensional Fatigue Inventory, Gießener Beschwerdebogen, Screening für Somatoforme Störungen und Nottingham Health Profile) zeigten, dass eine auf sieben Items reduzierte Kurzskala der Gesamtskala mit 14 Items ebenbürtig ist. Für differenzierte Analysen wird jedoch die Originalskala empfohlen. Durch die angegebenen Normwerte ist es künftig besser möglich, Patientengruppen verschiedener Alters- und Geschlechtsverteilungen untereinander oder auch mit Stichproben der Normalbevölkerung zu vergleichen.

Abstract
BACKGROUND Predictors of treatment outcome were evaluated in a clinical sample suffering from hypochondriasis. METHODS The sample consisted of 96 patients with hypochondriacal disorder according to DSM-IV or high syndrome scores on the Illness Attitude Scales (IAS) or Whiteley Index (WI). After intense inpatient cognitive-behavioral treatment (CBT), 60% of the patients were classified as responders because of substantial improvements or recovery from hypochondriacal symptomatology. RESULTS Non-responders were characterized by a higher degree of pre-treatment hypochondriasis, more somatization symptoms and general psychopathology (SCL-90R), more dysfunctional cognitions related to bodily functioning, higher levels of psychosocial impairments, and more utilization of the health care system as indicated by the number of hospital days and costs for inpatient treatments and medication. No predictive value was found for sociodemographic variables, comorbidity with other mental disorders and chronicity. Multiple linear regression showed that pre-treatment variables significantly predicted IAS scores at post-treatment (R(2) = 0.59), changes during treatment (0.10), IAS scores at follow-up two years later (0.41) and changes between baseline and follow-up (0.25). CONCLUSIONS The results demonstrate the relevance of various psychopathological variables and health care utilization as important indicators for outcome and further course of clinical hypochondriasis.

Abstract
OBJECTIVE Although somatoform disorders are assumed to be chronic clinical conditions, epidemiological knowledge on their natural course based on representative samples is not available. METHOD Data come from a prospective epidemiologic study of adolescents and young adults in Munich, Germany. Respondents' diagnoses (N = 2548) at baseline and follow-up on average 42 months later are considered. The follow-up incidence, stability as well as selected baseline risk factors (sociodemographics, psychopathology, trauma exposure) for the incidence and stability of somatoform disorders and syndromes are prospectively examined. Diagnostic information was assessed by using the standardized Munich-Composite International Diagnostic Interview (M-CIDI). RESULTS Over the follow-up period, incidence rate for any of the covered somatoform diagnoses was 25.7%. Stability for the overall group of any somatoform disorder/syndrome was 48%. Female gender, lower social class, the experience of any substance use, anxiety and affective disorder as well as the experience of traumatic sexual and physical threat events predicted new onsets of somatoform conditions, while stability was predicted by being female, prior existing substance use, affective and eating disorders as well as the experience of a serious accident. CONCLUSIONS At least for a substantial proportion of individuals, the overall picture of somatization seems to be relatively stable, but with fluctuation in the symptom picture over time. Being female, the experience of substance use as well as anxiety disorder seem to constitute risk factors for the onset of new somatoform conditions as well as for a stable course over time.

Abstract
Although hypochondriasis has been one of the most durable disease concepts in psychopathology, little is known about its epidemiology and treatment. In this article, we review the last three decades of research into these two aspects of hypochondriasis. According to DSM-IV, hypochondriasis is a distressing preoccupation with the fear or thought, based on physical sensations, that one has a serious disease. The prevalence of hypochondriasis in the general population is unknown; however, studies in primary care suggest that the prevalence in this setting is between 0.8 and 4.5%. There are, at present, no conclusive data about specific risk factors for hypochondriasis, although patients with hypochondriasis have higher rates of anxiety, depressive and other somatoform disorders than patients without the disorder. To date, there have been no studies documenting a genetic or familial predisposition for hypochondriasis, or for somatoform disorders in general. Cognitive behavioural therapy has been shown in controlled studies to be efficacious in the treatment of hypochondriasis. Although the evidence is stronger for individual therapy, group cognitive-behavioural therapy may also be useful. Other therapies such as supportive or psychoanalytical psychotherapy may be efficacious for certain patients, but the lack of standardised treatments and controlled studies makes them a less preferable treatment option at present. Little is known about the pharmacological treatment of primary hypochondriasis. The limited number of published studies and the absence of controlled trials make it impossible to be certain of the efficacy of existing medications. On the basis of the available information, however, it appears that the selective serotonin reuptake inhibitors hold promise for the treatment of this disorder. However, more information is needed for their efficacy to be clearly established.

Abstract
OBJECTIVE Somatosensory amplification has been defined as the tendency to experience normal bodily sensations as intense, noxious, and disturbing. The present experiment investigated whether this tendency is due to heightened physiological sensitivity to bodily sensations. METHODS The relationship between Somatosensory Amplification Scale (SSAS) scores and objective measures of the ability to detect bodily (ie, heartbeat) sensations derived from the Method of Constant Stimuli procedure was assessed. Although somatosensory amplification characterizes hypochondriacs, the relationship between somatosensory amplification and sensitivity to bodily sensations was examined in nonhypochondriacal, nonpatient participants in an effort to dissociate somatosensory amplification from other variables associated with hypochondriasis and/or patient status. RESULTS Heartbeat detectors were found to exhibit significantly lower SSAS scores than nondetectors. CONCLUSION This finding suggests that somatosensory amplification is not due to heightened sensitivity to bodily sensations.

Abstract
1. Despite the high prevalence of hypochondriasis, this disorder is found to be the focus of research only minimally. 2. This open study evaluates the efficacy and tolerance of paroxetine in 11 patients with DSM-III-R hypochondriasis. 3. Using paired samples t-test, a significant reduction on measures of hypochondriasis was found after 12 weeks of treatment compared to baseline. Two patients dropped out prematurely. At post-test, eight out of nine patients who completed the study had improved to a clinically relevant degree. Of these, five attained scores in the reach of the normal population. 4. In one patient who completed the study and one patient who dropped out, tolerance of paroxetine was poor, whereas in remaining patients tolerance was moderate to good. 5. The results of this study suggest that patients with hypochondriasis may be responsive to paroxetine. A controlled study is recommended.

Abstract
Between 5% and 9% of primary care patients exhibit hypochondriacal symptoms. Hypochondriasis may be primary or secondary to panic disorder or depression. Despite negative diagnostic findings and clinician reassurance, hypochondriacal patients manifest disease conviction, disease phobia, or both. Primary care providers, in collaboration with mental health care providers, can provide optimal treatment for patients with hypochondriasis. The use of various intervention phases and selective serotonergic reuptake inhibitors provide the most favorable patient outcomes.

Abstract
Hypochondriasis is frequently defined as a chronic condition distinct from anxiety and depressive disorders. Consecutive primary care attenders (n=25,916) were screened using the General Health Questionnaire and a stratified random sample (n=5447) completed a baseline diagnostic assessment. All patients with significant psychiatric symptoms and a random sample of remaining patients (n=3201) were asked to complete a follow-up diagnostic assessment 12 months later. Of patients meeting an abridged definition of hypochondriasis at baseline, 18% continued to do so at follow-up and an additional 16% continued to report hypochondriacal worries. 45% of those with hypochondriasis at follow-up also met criteria for DSM-IV anxiety or depressive disorder. Follow-up anxiety or depressive disorder was significantly associated with both onset and persistence of hypochondriasis. Hypochondriasis is moderately stable over time. The clear distinction between hypochondriasis and anxiety/depressive disorders suggested by ICD-10 and DSM-IV may be difficult to accomplish in practice.

Abstract
The authors studied interventions recommended by consultation-liaison (C-L) psychiatrists when they diagnosed somatoform disorder prospectively in a cohort of 4,401 consecutive inpatients referred to the C-L psychiatry service of a general teaching hospital, using standardized MICRO-CARES methodology. A DSM-III-R somatoform disorder was diagnosed in 2.9%, somatoform pain disorder in 1.4%, conversion disorder in 0.7%, hypochondriasis or somatization disorder undifferentiated/not otherwise specified in 0.6%, and somatization disorder in 0.2%. In 3.4%, somatoform disorder was considered a differential diagnosis. Psychiatric comorbidity included mood disorder (39%), personality disorder (37%), and psychoactive substance use disorder (19%). Recommendations were made about antidepressants in 40% of the patients, anxiolytics in 18%, sedatives in 18%, and antipsychotics in 10%. Psychiatrists recommended the following: more laboratory tests for 14%; additional medical/surgical consultations for 11%; an increase in the vigor of medical treatment for 13%; and psychological treatment for 76%; also they stressed an earlier discharge of 16%. Psychiatrists were more likely to request a prolongation of inpatient stay for patients with comorbid somatoform, mood, anxiety, and personality disorder. Differences in characteristics and treatment of the subgroups tended to be consistent with their constructs and comorbid psychiatric diagnoses.

Abstract
Hypochondriasis is a heterogeneous disorder. This was well demonstrated in the study by Kellner et al, which showed that patients with high levels of disease fear tended to be more anxious or phobic, whereas patients with high levels of disease conviction tended to have more and more severe somatic symptoms. Little comorbidity exists to support the statement that hypochondriasis is an obsessive-compulsive spectrum disorder. Although patients exist whose hypochondriac concerns are identical in quality to the intrusive thoughts of patients with OCD, as a group, patients with hypochondriasis do not share a comorbidity profile comparable with that of patients with OCD. The data support a closer relationship between hypochondriasis and somatization disorder than between hypochondriasis and OCD. The family history data is limited by the lack of adequate studies. Using comparable methods of the family history approach, Black's study reported a higher frequency of GAD but not OCD among the relatives of OCD patients--a finding similar to what Noyes found among the relatives of hypochondriac patients; however, using the direct interview method, somatization disorder was the only statistically more common disorder, among relatives of female hypochondriac patients. Therefore, although the parallel in overlap with GAD is suggestive of a commonality between OCD, GAD, and hypochondriasis, the finding of a greater frequency of somatization disorder leans against the hypothesis that hypochondriasis is best considered an OCD spectrum disorder. The pharmacologic treatment data are the one type of biologic evidence that supports a bridge to OCD. The pharmacologic studies suggest that for patients with general hypochondriasis, TCAs are not effective and that higher dosages and longer trials of the SRIs are needed. These pharmacologic observations are comparable with the ones made for patients with OCD but dissimilar to the observations made for depression. The benefit of imipramine among patients with illness phobia must be assessed in placebo-controlled trials among illness phobics and among hypochondriacs. Even more valuable would be a direct comparison of a TCA (e.g., imipramine or desipramine) and a selective SRI (e.g., fluoxetine) to determine whether the response to selective SRIs is greater. Although the pharmacologic data are compelling in supporting the hypothesis that hypochondriasis is an obsessive-compulsive spectrum disorder, the comorbidity data are equally compelling in dispelling that hypothesis. Perhaps future studies clarify the subtypes of hypochondriasis, be they "phobic, obsessive, and depressive," "chronic and episodic," "early onset versus late onset" or some other as yet undetermined subtype. Such clarification may be aided by better instruments to assess the obsessive-compulsive and hypochondria spectrums within individuals and families and by neuropsychological or pharmacologic challenge and neuroimaging studies.

Abstract
The medically unexplained complaint is often a symptom of hypochondriacal concerns. Patients with hypochondriasis may be managed with either naive realism or consideration of morbid categorization or via dimensional assessment of illness beliefs and behaviors. Naive realism will foster focus somatization and promote regression as well as lead to needless tests and treatments. Attention to categorical entities such a major depression or anxiety disorders will alert the clinician to comorbid psychiatric disorders that respond to traditional psychiatric treatments. Finally, by assessing the domains of illness behaviors such as disease conviction, beliefs in organic versus psychological causes, and denial, the clinician can document and then confront abnormal cognitive schema that revolve around somatic concerns that are a proxy for psychosocial difficulties.

Abstract
Although hypochondriasis is generally believed to be a chronic and refractory disorder, relatively little is known about its natural history and course. Based on a cognitive/perceptual model of hypochondriasis, we hypothesized that the disorder would be more chronic in patients who both amplify benign bodily symptoms and tend to attribute them to disease. Thirty-eight patients with DSM hypochondriasis were assessed with a structured, diagnostic interview and self-report questionnaire. A logistic regression model containing sociodemographic characteristics and a 3-way interaction term composed of the tendency to amplify bodily sensations, the tendency to attribute common symptoms to disease, and somatization (all measured at inception) correctly classified the remission status of 81.6% of the patients at follow-up 4 years later. These results suggest that patients who somatize, who are amplifiers of bodily sensation, and those who tend to attribute ambiguous symptoms to disease have more chronic and more refractory hypochondriasis. It is the co-occurrence of these cognitive and perceptual characteristics, rather than their occurrence individually, which predicts the persistence of this disorder.
