Course of hypochondriasis in an international primary care study

Health Anxiety Predicts the Perceived Dangerousness of COVID-19 over and above Intrusive Illness-Related Thoughts, Contamination Symptoms, and State and Trait Negative Affect

This study sought to evaluate the specificity of health anxiety, relative to other forms of psychopathology, in perceptions of COVID-19 as dangerous. Measures of health anxiety, COVID-19 perceived dangerousness, negative affect, anxiety, depression, stress, contamination-related obsessions and compulsions, and intrusive illness-related thoughts were administered online to 742 community individuals during the Italian national lockdown. Results showed that, after controlling for demographic variables and other internalizing problems, health anxiety was the single most important factor associated with the perceived dangerousness of COVID-19. Moreover, a comparison between the current sample's scores on various symptom measures and scores from prepandemic Italian samples revealed that, whereas other internalizing symptoms increased by a large or very large magnitude during the pandemic, levels of health anxiety and negative affect increased by a medium amount. This result may indicate that health anxiety is relatively trait-like, increasing the likelihood that our correlational data support the model of health anxiety as a vulnerability rather than an outcome. Together, these results indicate that health anxiety may be a specific risk factor for COVID-related maladjustment and support the distinction of health anxiety from other psychological problems.

Illness Anxiety Disorder: Psychopathology, Epidemiology, Clinical Characteristics, and Treatment

Illness anxiety disorder is a primary disorder of anxiety about having or developing a serious illness. The core feature is the cycle of worry and reassurance seeking regarding health, as opposed to a focus on relief of distress caused by somatic symptoms (as in Somatic Symptom Disorder). Clinically significant health anxiety is common, with estimates ranging up to 13% in the general adult population. There are evidence-based treatments, including psychopharmacology and cognitive behavioral therapy, that can significantly alleviate symptoms. An understanding of the core psychopathology and clinical features of illness anxiety disorder is essential to fostering a working alliance with patients with health anxiety, as is the maintenance of an empathic, curious, and nonjudgmental stance toward their anxiety. Collaboration between medical providers is essential to avoid the pitfalls of excess testing and medical treatment.

Hypochondriasis: Clinical Profile in a Tertiary Care Psychiatry and Neurosciences Hospital in Southern India - A Retrospective Chart Review

BACKGROUND

Hypochondriasis is a complex disorder in the realm of psychosomatic medicine, yet understudied in India. The aim of this study was to assess the clinical profile of patients diagnosed with hypochondriasis.

MATERIALS AND METHODS

Retrospective chart review was done in a tertiary care psychiatry and neurosciences hospital in southern India. Medical records of adults diagnosed with hypochondriasis between 2000 and 2010 were analyzed. These patients were also rediagnosed retrospectively using Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for illness anxiety disorder (IAD) and Diagnostic Criteria for Psychosomatic Research (DCPR) criteria for health anxiety and illness phobia. Data were organized and analyzed using PSPP for descriptive statistics of different variables.

RESULTS

There were 114 patients with hypochondriasis, with the most common belief being about dysmorphic appearance. Selective serotonin reuptake inhibitors (SSRIs) were the most commonly prescribed medications. The median follow-up duration was only 2 months. Five percent of the cases fulfilled the criteria for DCPR health anxiety and 20.4% for DCPR illness phobia. DSM-5 criteria for IAD were fulfilled by 45.6% of the cases.

CONCLUSION

Dysmorphic appearance was the most common concern in patients with hypochondriasis and SSRIs the most common medications. The follow-up rate and the diagnostic concurrence with DSM-5 IAD and DCPR were low. Studies assessing the influence of psychopathology and culture on the presentation, course, and prognosis of hypochondriasis would be beneficial.

Hypochondriac concerns and correlates of personality styles and affective states in bipolar I and II disorders

BACKGROUND

Hypochondriac concerns are associated with the treatment-difficulty of bipolar disorder, which might be due to the personality styles and affective states.

METHODS

We invited outpatients with bipolar I disorder (BD I, n = 87), bipolar II disorder (BD II, n = 92) and healthy volunteers (n = 129) to undergo the Illness Attitude Scales and Parker Personality Measure tests, and measurements of concurrent affective states.

RESULTS

Compared to healthy volunteers, BD I and BD II patients scored significantly higher on mania, hypomania and depression. BD I and BD II patients also scored significantly higher on Symptom Effect and Treatment Seeking, and BD II patients scored higher on Patho-thanatophobia and Hypochondriacal Belief. BD II in addition scored higher on Patho-thanatophobia than BD I did. In controls, the Dependent style predicted Patho-thanatophobia and Symptom Effect, Schizoid with Hypochondriacal Belief; in BD I, Narcissistic (-) with Hypochondriacal Belief, Histrionic with Patho-thanatophobia and Hypochondriacal Belief, depression with Hypochondriacal Belief, and hypomania with Symptom Effect and Hypochondriacal Belief; in BD II, depression with Symptom Effect and Hypochondriacal Belief, mania with Symptom Effect.

CONCLUSIONS

Bipolar disorder, especially BD II, is associated with greater hypochondriac concerns, which relates to personality disorder functioning styles and concurrent affective states.

Cognitive-behavioral therapy for hypochondriasis/health anxiety: a meta-analysis of treatment outcome and moderators

The present investigation employed meta-analysis to examine the efficacy of cognitive-behavioral therapy (CBT) for hypochondriasis/health anxiety as well as potential moderators that may be associated with outcome. A literature search revealed 15 comparisons among 13 randomized-controlled trials (RCTs) with a total sample size of 1081 participants that met inclusion criteria. Results indicated that CBT outperformed control conditions on primary outcome measures at post-treatment (Hedges's g = 0.95) and at follow-up (Hedges's g = 0.34). CBT also outperformed control conditions on measures of depression at post-treatment (Hedges's g = 0.64) and at follow-up (Hedges's g = 0.35). Moderator analyses revealed that higher pre-treatment severity of hypochondriasis/health anxiety was associated with greater effect sizes at follow-up visits and depression symptom severity was significantly associated with a lower in effect sizes at post-treatment. Although effect size did not vary as a function of blind assessment, smaller effect sizes were observed for CBT vs. treatment as usual control conditions than for CBT vs. waitlist control. A dose response relationship was also observed, such that a greater number of CBT sessions was associated with larger effect sizes at post-treatment. This review indicates that CBT is efficacious in the treatment of hypochondriasis/health anxiety and identifies potential moderators that are associated with outcome. The implications of these findings for further delineating prognostic and prescriptive indicators of CBT for hypochondriasis/health anxiety are discussed.

Emerging themes in the revision of the classification of somatoform disorders

The somatoform disorders, as currently defined in DSM-IV and ICD-10, have been criticized for their complexity and poor clinical utility. In this paper we consider these criticisms as well as the conceptual question of whether there is sufficient evidence for classifying them as mental and behavioural disorders. The review suggests that, as currently defined, somatoform disorders do not fulfil a recently articulated set of criteria for mental and behavioural disorders. In particular, the disorders are not defined according to positive psychological and behavioural disorders and evidence is sparse to support their classification as different and distinct diagnoses. Any revision of the disorders should not be based on 'medically unexplained' symptoms. Rather, the relevant diagnoses should include a combination of bothersome somatic symptoms with several other psychological features including beliefs about somatic symptoms and evidence of marked concerns about health and illness. Finally, the review presents a set of proposals for the revision of these disorders, by the Somatic Disorders and Dissociative Disorders Working Group of the WHO International Advisory Group for the Revision of ICD-10 Mental and Behavioural Disorders, which attempt to take account of the criticisms and current understanding of somatic experiences.

The outcome of health anxiety in primary care. A two-year follow-up study on health care costs and self-rated health

Background

Hypochondriasis is prevalent in primary care, but the diagnosis is hampered by its stigmatizing label and lack of valid diagnostic criteria. Recently, new empirically established criteria for Health anxiety were introduced. Little is known about Health anxiety's impact on longitudinal outcome, and this study aimed to examine impact on self-rated health and health care costs.

Methodology/Principal Findings

1785 consecutive primary care patients aged 18–65 consulting their family physicians (FPs) for a new illness were followed-up for two years. A stratified subsample of 701 patients was assessed by the Schedules for Clinical Assessment in Neuropsychiatry interview. Patients with mild (N = 21) and severe Health anxiety (N = 81) and Hypochondriasis according to the DSM-IV (N = 59) were compared with a comparison group of patients who had a well-defined medical condition according to their FPs and a low score on the screening questionnaire (N = 968). Self-rated health was measured by questionnaire at index and at three, 12, and 24 months, and health care use was extracted from patient registers. Compared with the 968 patients with well-defined medical conditions, the 81 severe Health anxiety patients and the 59 DSM-IV Hypochondriasis patients continued during follow-up to manifest significantly more Health anxiety (Whiteley-7 scale). They also continued to have significantly worse self-rated functioning related to physical and mental health (component scores of the SF-36). The severe Health anxiety patients used about 41–78% more health care per year in total, both during the 3 years preceding inclusion and during follow-up, whereas the DSM-IV Hypochondriasis patients did not have statistically significantly higher total use. A poor outcome of Health anxiety was not explained by comorbid depression, anxiety disorder or well-defined medical condition. Patients with mild Health anxiety did not have a worse outcome on physical health and incurred significantly less health care costs than the group of patients with a well-defined medical condition.

Conclusions/Significance

Severe Health anxiety was found to be a disturbing and persistent condition. It is costly for the health care system and must be taken seriously, i.e. diagnosed and treated. This study supports the validity of recently introduced new criteria for Health anxiety.

Medically unexplained symptoms, somatisation disorder and hypochondriasis: course and prognosis. A systematic review

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.

Psychotherapies for hypochondriasis

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.

Distinguishing between hypochondriasis and somatization disorder: a review of the existing literature

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.

General medical and psychiatric perspectives on somatoform disorders: separated by an uncommon language

PURPOSE OF REVIEW

While Diagnostic and Statistical Manual of Mental Disorders-IV provided updated definitions and diagnostic criteria for the diagnoses subsumed under the category of somatoform disorders, various nosological questions are still unresolved. We assessed current research activity on important key concepts related to nosology, validity, and reliability of the Diagnostic and Statistical Manual of Mental Disorders-IV somatoform diagnoses.

RECENT FINDINGS

The initial Medline search for articles from 2000 through 2005 yielded a total of 912 articles. After checking for redundancy and excluding publications using other than Diagnostic and Statistical Manual of Mental Disorders-IV diagnostic criteria, a total of 101 articles was further reviewed. Heterogeneity of papers precluded statistical approaches; thus, a descriptive and narrative review was pursued.

SUMMARY

It appears that applying the specific categories and criteria as proposed by Diagnostic and Statistical Manual of Mental Disorders-IV only captures a small proportion of the phenomena of interest at the interface of medicine and psychiatry. A paradigm shift towards 'general medical/psychiatry interface disorders' in exchange for the current dichotomy of 'mind' vs. 'body' disorders, may reduce stigma associated with current diagnostic labeling, improve user acceptability, and stimulate research in this important but still fragmented clinical area that still lacks agreed-upon diagnostic definitions.

A systematic review of the epidemiology of somatisation disorder and hypochondriasis

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.

What can we learn from a cross-national study of somatic distress?

OBJECTIVE

To examine the extent of cross-national variations in the rates and correlates of somatic distress and determine whether this can be ascribed to cultural differences.

METHODS

A two-stage survey in primary care across 15 sites in 14 countries. Screening with the 12-item General Health Questionnaire (GHQ-12) was followed with detailed diagnostic assessment with the Composite International Diagnostic Interview. Self-rating of overall health and evaluation of disability days were also conducted (N = 5438). Twelve months later, 3204 of the patients completed follow-up interviews.

RESULTS

Somatic distress (different definitions of somatization and of hypochondriasis as well as persistent pain disorder) varied in its occurrence across sites. However, other than elevated rates in Latin America, variation tends to be complex and does not lend itself to a neat cultural explanation. The nature of patient-doctor relationship is related to this variation.

CONCLUSION

Cross-national differences occur in somatic distress. The pattern of these differences does not follow clear cultural lines even though the role of culture cannot be excluded.

Predictors of course and outcome in hypochondriasis after cognitive-behavioral treatment

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.
