Understanding cyberchondria in pregnant women: longitudinal assessment of risk factors, triggers, and outcomes

Pregnancy often triggers anxiety and health concerns in women, leading many to search for health information online. Excessive, compulsive, and repetitive online health research, accompanied by heightened anxiety, can result in cyberchondria. This study aimed to explore the risk factors, triggers, and outcomes of cyberchondria in pregnant women. A total of 149 participants completed an online questionnaire longitudinally across three stages of pregnancy: early (14-19 weeks), mid (24-29 weeks), and late pregnancy (34-39 weeks). The findings revealed that health anxiety and the cognitive component of anxiety sensitivity are risk factors for cyberchondria during pregnancy. Pregnancy concerns related to motherhood emerged as triggers for cyberchondria. While a connection between cyberchondria and fear of birth was observed, fear of birth did not appear to be a direct outcome of cyberchondria. These results highlight the importance of addressing health anxiety, cognitive anxiety sensitivity and motherhood concerns in prenatal care and support interventions. Understanding the factors contributing to cyberchondria in pregnant women can assist healthcare professionals in providing targeted support and resources to mitigate excessive online health searching behaviors and alleviate anxiety during pregnancy.

The global economic burden of health anxiety/hypochondriasis- a systematic review

BACKGROUND

Recent studies have shown a lifetime prevalence of 5.7% for health anxiety/hypochondriasis resulting in increased healthcare service utilisation and disability as consequences. To the best of our knowledge, there has been no systematic review examining the global costs of hypochondriasis, encompassing both direct and indirect costs. Our objective was to synthesize the available evidence on the economic burden of health anxiety and hypochondriasis to identify research gaps and provide guidance and insights for policymakers and future research.

METHODS

A systematic literature search was conducted using PubMed, Web of Science, PsycInfo, EconLit, IBSS and Google Scholar without any time limit, up until April 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed in this search and the following article selection process. The included studies were systematically analysed and summarized using a predefined data extraction sheet.

RESULTS

Of the 3044 articles identified; 10 publications met our inclusion criteria. The results displayed significant variance in the overall costs listed among the studies. The reported economic burden of hypochondriasis ranged from 857.19 to 21137.55 US$ per capita per year. Most of the investigated costs were direct costs, whereas the assessment of indirect costs was strongly underrepresented.

CONCLUSION

This systematic review suggests that existing studies underestimate the costs of hypochondriasis due to missing information on indirect costs. Furthermore, there is no uniform data collection of the costs and definition of the disease, so that the few existing data are not comparable and difficult to evaluate. There is a need for standardised data collection and definition of hypochondriasis in future studies to identify major cost drivers as potential target point for interventions.

The Portrait of Cyberchondria-A Cross-Sectional Online Study on Factors Related to Health Anxiety and Cyberchondria in Polish Population during SARS-CoV-2 Pandemic

The SARS-CoV-2 pandemic has served as a magnifying glass for cyberchondria, while the internet emerged as one of the main sources of medical information and support. The core ambition of this study was to estimate the level of cyberchondria and describe the socio-demographic, clinical and pandemic-related factors affecting its severity amid the SARS-CoV-2 pandemic. A cross-sectional study was performed between 16 May 2020 and 29 December 2020 in Poland within a sample of 538 adult internet users. The online survey tool included a Polish adaptation of the Cyberchondria Severity Scale (CSS-PL) and the Short Health Anxiety Inventory (SHAI), complemented with a set of questions covering sociodemographic, clinical and pandemic-related factors. Participants were clustered according to severity of health anxiety and cyberchondria symptoms. The performed binary logistic regression indicated professional inactivity, having a chronic mental disorder and subjectively limited access to healthcare due to COVID-19 to be key determinants of severe health anxiety and cyberchondria. Cyberchondria might be a remarkable public health issue as large proportion of respondents from the analyzed sample population of internet users met the criteria for severe symptoms. Key determinants of intense cyberchondria corresponded with employment stability, mental resilience and accessibility of healthcare services, which could be greatly challenged amid the pandemic.

Cyberchondria in the age of COVID-19

The global epidemic of (mis)information, spreading rapidly via social media platforms and other outlets, can be a risk factor for the development of anxiety disorders among vulnerable individuals. Cyberchondria can be a vulnerability factor for developing anxiety in a pandemic situation, particularly when the Internet is flooded with (mis)information. The aim of our study was to examine how cyberchondria is related to changes in levels of COVID-19 concern and safety behaviours among persons living in Croatia during the period in which the first COVID-19 case was identified and when the country recorded its first fatality. Repeated cross-sectional data collection was conducted during two waves over a period of three weeks (N1 = 888; N2 = 966). The first began on the day of the first confirmed case of COVID-19 in Croatia (February 24th, 2020) and the second wave began three weeks later, on the day the first COVID-19 fatality was recorded in Croatia (March 19th, 2020). Participants completed an online questionnaire regarding various COVID-19 concerns and safety behaviours aimed at disease prevention (information seeking, avoidance and hygiene) and a measure of cyberchondria (Short Cyberchondria Scale, SCS). We analysed whether changes to the epidemiological situation during the period between the two waves of data collection led to an increase in COVID-19 related behaviour directly and indirectly via an increase in COVID-19 concerns. The results indicated that, between the two waves of research, there was a pronounced increase in concerns regarding COVID-19 (b = 1.11, p < .001) as well as significant behavioural changes (b = 1.18-2.34, p < .001). Also, results demonstrated that cyberchondria plays a moderating role in these changes. In the first wave, persons with severe cyberchondria were already intensely concerned with safety behaviours. High cyberchondria and high levels of concern about the COVID-19 are associated with intense avoidance behaviours, R2 = .63, p < .001. A moderated partial mediation model was confirmed, in which the effect of the epidemiological situation was weaker for those with higher results on the SCS (as indicated by index of moderated mediation between -.10 and -.15, p < .05). As such, cyberchondria is a contributing factor to long-term anxiety and its impact during pandemic on the general mental health burden should therefore be further investigated.

Psychological Aspects and Eating Habits during COVID-19 Home Confinement: Results of EHLC-COVID-19 Italian Online Survey

The COVID-19 pandemic has had a huge impact on the population with consequences on lifestyles. The aim of the study was to analyse the relationship between eating habits, mental and emotional mood. A survey was conducted online during social isolation, from 24 April to 18 May 2020, among the Italian population. A total of 602 interviewees were included in the data analysis. A high percentage of respondents experienced a depressed mood, anxious feelings, hypochondria and insomnia (61.3%, 70.4%, 46.2% and 52.2%). Almost half of the respondents felt anxious due to the fact of their eating habits, consumed comfort food and were inclined to increase food intake to feel better. Age was inversely related to dietary control (OR = 0.971, p = 0.005). Females were more anxious and disposed to comfort food than males (p < 0.001; p < 0.001). A strength of our study was represented by the fact that the survey was conducted quickly during the most critical period of the Italian epidemic lockdown. As the COVID-19 pandemic is still ongoing, our data need to be confirmed and investigated in the future with larger population studies.

Prevalence of hypochondriac symptoms among health science students in China: A systematic review and meta-analysis

BACKGROUND

Hypochondriac symptoms are commonly reported in health science students. With their incomplete medical knowledge, they may compare their own bodily symptoms with disease symptoms during the process of learning, which can lead to mental distress and the need for repeated medical reassurance.

OBJECTIVE

To estimate the prevalence of hypochondriac symptoms in Chinese health science students.

METHODS

A systematic literature search was conducted on PubMed, Web of Science, Embase, China National Knowledge Infrastructure, China Biology Medicine disc, and Wanfang Data on July 1, 2018. Additionally, the references of the retrieved papers were searched. Cross-sectional studies published in either English or Chinese that reported the prevalence of hypochondriac symptoms in health science students were included. The selection process was executed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, and study quality was assessed with the checklist recommended by the Agency for Healthcare Research and Quality for cross-sectional studies. A random-effects model according to the DerSimonian-Laird method was used to calculate the pooled prevalence.

RESULTS

Seven cross-sectional studies involving 6,217 Chinese health science students were included. The pooled prevalence of hypochondriac symptoms among health science students was 28.0% (95% CI = 19.0%-38.0%). The symptoms were a little more common in females (30.0%, 95% CI = 19.0%-42.0%) than in males (29.0%, 95% CI = 16.0%-42.0%), but the difference was not significant. No significant differences were found between participants grouped by study year. Only three studies explored the coping styles of students with hypochondriasis, and these revealed a high tendency toward help-seeking behaviors.

CONCLUSION

Our systematic review and meta-analysis showed a high prevalence of hypochondriac symptoms among health science students, indicating that it is a noteworthy phenomenon. We suggest that counseling and other support services are necessary for health science students.

Adult Attachment, Reassurance Seeking and Hypochondriacal Concerns in College Students

An individual’s attachment style can be conceptualized as a working model for interactions with others, developed as result of experiences with childhood caregivers. People with hypochondriacal tendencies are preoccupied with thoughts of having an illness and constantly seek medical reassurance. We hypothesized that students with preoccupied attachment would score highly on a measure of hypochondriasis and investigated whether the association would be explained by the general tendency to seek reassurance in relationships. A total of 117 undergraduate students completed questionnaires measuring attachment style; negative affectivity; reassurance seeking in relationships and hypochondriasis. Participants with preoccupied attachment style ( n = 17, 15%) had significantly higher hypochondriasis scores than those with other attachment styles. Hierarchical multiple regression analysis suggested that the association between the preoccupied attachment style and hypochondriasis was explained by the general tendency to seek reassurance in relationships, with negative affectivity, a dispositional variable, also acting as a significant predictor of hypochondriasis.

Health-Related Anxiety and Hypochondriacal Concerns in Medical Students: A Cross-Sectional Study From Pakistan

Phenomenon: Transient health-related anxiety/hypochondriacal concerns in medical students are well documented. The literature suggests that after studying a particular disease, medical students are likely to consider any symptoms earlier regarded as normal to be signs of the disease they are studying. The aim of this study was to investigate the prevalence of these phenomena and their cognitive and distress aspects among medicals students in Karachi, Pakistan.

APPROACH

This was an analytical, cross-sectional study. Self-administered questionnaires comprising demographic details, the Short Health Anxiety Inventory, Medical Students' Disease (MSD) Perception Scale, and MSD Distress Scale were distributed to 1st- through 5th-year medical students.

FINDINGS

In total, 513 medical students (66% female) participated. Their mean age was 21 ± 1.6 years. Three hundred seventy-five students (73%) reported having visited a doctor at least once in the past 6 months. Fifty students (9.9%) admitted to having addictions. The overall prevalence of significant hypochondriacal concerns was 11.9% (61 students). The presence of addiction was associated with a greater likelihood of developing significant health-related anxiety (odds ratio = 3.82, p = .003), 95% confidence interval [1.51, 7.11]. Age, gender, medical school, year of medical school, and visits to the doctor in the previous 6 months were not associated with greater likelihood of developing significant health-related anxiety. Second-year medical students experienced a significantly greater degree of worry (MSD-Distress scale) than 5th-year students (M score = 12.6 ± 4.6 vs. 10.7 ± 4.4, p = .04). Insights: The prevalence of substantial hypochondriacal concerns in medical students in Pakistan was low in comparison to similar studies published in literature. Student health physicians should be aware of the true prevalence of hypochondriacal concerns and behavior and not dismiss legitimate complaints. Educational sessions to counteract this phenomenon can be incorporated into the curriculum of undergraduate medicine. By defining heightened awareness of symptoms as a normal process, different coping techniques can be discussed to help medical students reduce their level of stress.

Confirmatory factor analysis and item response theory analysis of the Whiteley Index. Results from a large population based study in Norway. The Hordaland Health Study (HUSK)

OBJECTIVE

The Whiteley Index (WI) is a widely used screening instrument for health anxiety/hypochondriasis. Several studies have previously explored the psychometric properties of the WI, but with mixed findings concerning both item composition and factor structure. The main aim of the current study was to examine different factor structures as identified from previous studies using data from a large general population based study. We also wanted to provide gender specific norms.

METHODS

Data were taken from a large population-based study in Norway, the Hordaland Health Study (HUSK N=7274). Confirmatory factor analysis (CFA) of several models of the WI was conducted. Item response theory (IRT) analysis was performed on the model with the best goodness-of-fit.

RESULTS

CFA of all previously proposed factor models of the WI revealed clearly inadequate model fits. The IRT analysis suggested that a six-item model best described the data, and CFA confirmed an adequate goodness-of-fit across indices.

CONCLUSION

The current study found evidence for a six-item, single-factor model of the WI. Our findings suggest that this abbreviated version has the best factor structure compared to previously proposed factor models. We recommend that the factor structure identified in this study should be investigated further in independent samples.

Childhood maltreatment is associated with depression but not with hypochondriasis in later life

OBJECTIVE

Previous studies demonstrated that a history of childhood trauma is linked to mental disorders in adulthood, particularly to depression. Adverse childhood experiences are also considered to contribute to the risk of hypochondriasis, but the results of previous studies have not been conclusive with respect to the strength and specificity of this association. Therefore, we compared the association of adverse childhood experiences with both hypochondriasis and depression.

METHODS

Fifty-eight patients with hypochondriasis, 52 patients with depression, and 52 healthy control participants completed the Childhood Trauma Questionnaire (CTQ) which assesses 5 varieties of abuse and neglect. A clinical interview (SCID-I) was used to establish DSM-IV diagnoses. Associations between childhood maltreatment, hypochondriasis and depression were estimated by means of analyses of variance and multiple linear regression analyses.

RESULTS

In comparison to hypochondriacal and healthy participants, patients with a current depressive disorder reported more emotional abuse as well as more emotional and physical neglect during childhood. Patients with hypochondriasis reported more emotional neglect than healthy individuals. However, when predicting the CTQ trauma types by diagnostic category adjusting for sex and comorbid DSM-IV diagnoses, emotional abuse, emotional neglect, physical abuse, physical neglect, as well as the CTQ total score were significantly associated with depression, but none of the CTQ scores was significantly related to hypochondriasis.

CONCLUSIONS

The findings suggest a robust association of childhood maltreatment with depression but not with hypochondriasis. This result does not support etiological models of hypochondriasis which rely on childhood maltreatment as a risk factor for the development of this disorder.

[Hypochondriac symptoms in late-onset depression: the relationship between hypochondria and somatic state of patients]

Authors studied 276 women with late-onset depression. Concomitant chronic somatic diseases were identified in 90%. The presence of disease and its nosological definition did not impact on the development of hypochondriac symptoms in patients with late-onset depression. Patients with hypochondriac late-onset depression more often had disability pension due to somatic disease because they more often referred to internists in case of similar objective severity of somatic pathology. It was singled out three variants of the relationship between hypochondria and somatic state: hypernosognostic (a complete coincidence of hypochondria content with actual somatic pathology; anosognostic (a lack of coincidence) and disharmonic (a partial coincidence). The themes of hypochondria in late-nset depressions were correlated with a total number of somatic diseases and their severity. At the same time, there was no correlation between the content of hypochondria and the character of somatic disease.

Are fatigue symptoms and chronic fatigue syndrome following Q fever infection related to psychosocial variables?

OBJECTIVE

Fatigue is known as one of the most common long-term sequelae of Q fever infections. The study aimed to determine the prevalence of fatigue symptoms, chronic fatigue, and chronic fatigue syndrome (CFS) in a sample of patients who were exposed to Q fever (Coxiella burnetii) infection compared to controls, and to contrast Q fever patients with and without fatigue symptoms related to somatoform symptoms, hypochondriacal worries and beliefs, psychosocial complaints, and social support.

METHODS

Cross-sectional study of 84 Q fever exposed patients from a specific region in Jena (Germany) and 85 matched controls using standardized questionnaires (MFI, SF-12, CDC-SI, SOMS, Whiteley Index, OQ-45 and F-Sozu). Diagnostic interviews were performed to validate questionnaire results in a smaller subsample.

RESULTS

Patients who were exposed to a Q fever infection in the past indicated more fatigue symptoms and chronic fatigue than controls (54.8 vs. 20%, 32.1 vs. 4.7%) but did not show more criteria for a CFS (1 patient in each group). Q fever patients showing fatigue symptoms revealed significantly higher scores in the SOMS, the Whiteley-Index, and higher psychosocial complaints measured with the OQ-45. Their health related Quality of Life was reduced, no differences were found related to perceived social support.

CONCLUSION

Although in our sample fatigue symptoms were common among Q fever patients, we found no increased prevalence of CFS in contrast to several other studies. The combination of fatigue symptoms with other psychosocial symptoms/problems support the view of a biopsychosocial etiology of fatigue symptoms.

[Neurologic and neuro-psychologic changes in residents of Taraz town]

The study covered occurrence of clinical and psychologic disorders in cerebrovascular diseases. Examination involved 840 individuals aged 20 to 59 years. The examinees demonstrated early clinical manifestations of cerebrovascular diseases with vegetative dysfunction as asthenic and hypochondriacal syndromes. The encephalopathy course was characterized by prevailing asthenic and neurotic syndrome, with cognitive disorders and emotional depletion.

Prevalence of health anxiety problems in medical clinics

OBJECTIVES

To determine the prevalence of significant health anxiety (hypochondriasis) in patients aged 16-75 in cardiology, respiratory medicine, neurological, endocrine and gastrointestinal clinics in general hospitals in London, Middlesex and North Nottinghamshire.

METHOD

The Health Anxiety Inventory (HAI) (short form) was administered to patients attending the five clinics over a 21 month period and all those who scored 20 or more invited to take part in a further assessment for a randomised controlled trial.

RESULTS

Of 43,205 patients attending the clinics 28,991 (67.1%) were assessed and of these, after exclusion of ineligible patients 5747 (19.8%) had significant health anxiety. 444 subsequently agreed to take part in a randomised controlled trial of treatment. The prevalence levels varied by clinic with neurology (24.7%) having the highest prevalence followed by respiratory medicine (20.9%), gastroenterology (19.5%), cardiology (19.1%), and endocrinology (17.5%).

CONCLUSION

Abnormal health anxiety is common and a significant problem in those attending medical clinics and deserves greater awareness.

[Epidemiologic and clinical characteristics of 59 persons suspecting of being infected by the HIV virus despite having repeated negative laboratory findings]

OBJECTIVE

To describe the epidemiologic characteristics and clinical manifestations of 59 persons recruited via an internet chat group who complained of AIDS-like symptoms, so as to formulate effective intervention strategies and measures.

METHODS

Case was defined as onset of any three of the following self-reported AIDS-like symptoms in a member of relevant "internet chat groups": persistent low grade fever, rash, swollen lymph node, fatigue, diarrhea, weight loss and low CD4(+)T count. We administered an internet-based questionnaire, and invited 59 of the 88 case-persons for voluntary physical examination and laboratory testing.

RESULTS

The 59 case-persons came from 22 provinces; 54 (91.5%) were men; the median age was 34 (range: 22-53) years; 84.7% of them had high-risk sexual behaviors before the onset of self-reported symptoms. The median time interval from exposure to onset was 15 d (range: 1-365 d). Blood specimens for all the 59 case-persons were tested negative for HIV and syphilis antibodies. There was also no evidence of Xenotropic murine leukemia virus-related virus infection. One case-person was tested positive for hepatitis C virus antibody. The average CD4(+)T lymphocyte count was 707/µl. Of the 59 case-persons, 57 (96.6%) sought medical care from multiple providers; 40 were diagnosed to have no physical disorders.

CONCLUSION

None of the 59 case-persons had any evidence of infection with HIV or any other infectious agents that could explain their self-reported symptoms.

Comorbidity of kidney stones and psychiatric disease

This paper describes a patient who is suffering from PTSD with elements of hypochondria, panic attacks and episodes of depression in comorbidity with kidney stones. Kidney stones provoked egzacerbation of psychiatric symptoms. Kidney stones and frustration about them have taken part of provoking factor, the last drop, which led to regression of otherwise precarious, but compensated patient's mental functioning which resulted in development of psychiatric symptoms.

[Depression in elderly]

Depression is frequent among aged persons and its diagnosis is difficult, because certain clinical presentations are unusual, explaining undertreatment. Depression is observed not only in ancient depressive people but can also be shown on elderly without previous mood disorders. Somatic symptoms often mask depression. More over, somatic diseases can interfere with depression. A hypochondria is always associated with depression in old patients, patients expressing in this a particular way a psychological pain. Loss of motivation is sometime a depression in aged people, associated with a dysexecutive syndrome or, elsewhere, aggressiveness can reveals a hostile depression. At a worst stage of the disease, in particular, when a dementia is latent, confusion is present. A therapeutic test with an antidepressant can help to discriminate between a dementia with depressive symptoms or a depression with a confusion. But, even if the cognitive disorders disappear with the treatment, a dementia can appear years after.

Maternity blues in Athens, Greece: a study during the first 3 days after delivery

BACKGROUND

Although maternity blues have been studied in many countries worldwide the factors that influence the occurrence of this clinical entity are not well understood. The purpose of this study was to investigate the prevalence, time course and symptomatology of maternity blues in a Greek urban environment as well as the relation of maternity blues with certain clinical and sociodemographic factors.

METHOD

A study of a sample of 402 women that were recruited during the first day after delivery. Each woman completed the Kennerley's Blues Questionnaire on a daily basis for the first 3 days of puerpartum. Clinical and sociodemographic data were obtained through questionnaires and personal interview.

RESULTS

179 (44.5%) women experienced severe maternity blues during the first 3 days after delivery. Delivery by caesarian section (P=0.006), stressful events during pregnancy (P=0.02), depressive feelings the last month prior to delivery (P=0.002), anxiety on the day of delivery (P=0.001) and hypochondriasis (P=0.001) were the factors that were found to relate significantly to maternity blues.

CONCLUSION

The women's emotional condition prior and after delivery, delivery via caesarotomy, as well as fears concerning somatic health had strong impact on the occurrence of maternity blues.

The boundary between hypochondriasis and obsessive-compulsive disorder: a cross-sectional study from the Netherlands

OBJECTIVE

To investigate similarities and differences between the symptom profiles of patients with hypochondriasis and those of patients with obsessive-compulsive disorder (OCD) and to compare the contamination/cleaning OCD subtype to other OCD subtypes.

METHOD

Between January 1998 and July 2002, 76 patients diagnosed with hypochondriasis (N = 31) or OCD (N = 45) (DSM-IV criteria) and 25 subjects with no formal DSM-IV diagnosis were compared with regard to the extent of diagnosis-specific symptoms, the number and nature of physical symptoms, and whether these symptoms evoked fear. The analyses were repeated after subdividing the OCD patients into the contamination/cleaning and other OCD subgroups.

RESULTS

Patients with hypochondriasis and OCD differed significantly from each other on the extent of diagnosis-specific symptoms (all p < .001). Patients with hypochondriasis reported significantly more obsessive-compulsive symptoms and patients with OCD reported significantly more hypochondriacal symptoms than did the healthy control-group members (all p < .05). Neither group differed significantly from the other on the number and nature of feared physical symptoms. The contamination/cleaning OCD subtype did not differ significantly from other OCD subtypes in either the severity of hypochondriacal symptoms or the number of feared physical symptoms.

CONCLUSION

Hypochondriasis and OCD can be distinguished on the basis of diagnosis-specific symptoms, although they share a number of similarities. In addition, although patients with the contamination/cleaning OCD subtype tend to be afraid of contracting diseases, the differences between the symptom profiles of these patients and those of patients with hypochondriasis exceed the similarities. Our results confirm that the 2 conditions are separable and valid diagnoses.

Features of hypochondriasis and illness worry in the general population in Germany

OBJECTIVE

Although hypochondriasis is considered to be of high relevance in the healthcare sector, its prevalence in the general population has been investigated in few studies. The aims of this study were to estimate prevalence rates of hypochondriasis and of subthreshold conditions and to describe their associated features such as quality of life and healthcare utilization in a representative community sample.

METHODS

Analyses of the present study are based on the German Health Interview and Examination Survey-Mental Health Supplement (N = 4181, representative for the German population from 18-65 years). The assessment included interviews for somatic conditions and mental disorders and self-report ratings on health-related quality of life, healthcare utilization, disability days, and physical activity.

RESULTS

Only three cases (0.05%) were identified as meeting full criteria of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) hypochondriasis. The prevalence rate of the less restrictively defined form of hypochondriasis, ("subthreshold hypochondriasis") was 0.58% and an additional 2.12% reported having had illness worries for at least 6 months but did not meet further hypochondriasis criteria. The two subthreshold diagnostic groups provided strong evidence of difference from the nonhypochondriac controls: comorbidity with psychiatric and medical disorders and healthcare utilization were higher, and quality of life was markedly reduced.

CONCLUSIONS

The results provide additional support to not only consider "full" DSM-IV hypochondriasis, which is a very rare disorder in the general population, but also to include less restrictive hypochondriac conditions--associated with a clinically relevant degree of psychological and physical impairment--into clinical and scientific considerations.

Psychosocial aspects of acquired hearing impairment in the patients with otosclerosis

Currently available evidence reveals comparatively few studies of the psychological and social effects of acquired hearing impairment, in spite of the fact that clinicians have for a long time been aware of a connection between acquired hearing impairment and mental disorders. The existing data indicate that psychological disorders are significantly more frequent in a population with hearing impairment than in the average population and are accompanied by disharmony in interpersonal and social relations.

AIM

Establishing the presence and the type of mental disorders in patients with hearing impairment due to otosclerosis, before and 6 months after corrective surgery, as well as finding the role of adaptation style (personal adjustment) and facing strategy (communication strategies) as mediating variables between the acquired hearing impairment and observed psychical changes.

METHODOLOGY

in 60 subjects, potential candidates for stapedectomy, MMPI-201 has been applied before and after surgery, in order to evaluate the mental state. For assessments of personal adjustment to the impairment and communication strategies, a communication personal profile has been applied preoperatively.

RESULTS

more psychiatric disorders are present in the preoperative group compared to the general population and the postoperative group. These disorders are of exclusively a neurotic nature; the most frequent are depressive, anxious depressive and anxious reactions. A connection was found between adaptation style and facing strategies whether in the presence or absence of psychological disorders.

CONCLUSION

the findings indicate a need for professional psychiatric-psychological support as a part of a rehabilitation program designed to reduce psychological difficulties, i.e. to help individuals to become adapted to the acoustic environment and to prevent or at least minimize the negative consequences of hearing impairment by efficient communication strategies.

Somatoform disorders in the workplace in Japan

The literature related to somatoform disorders in the workplace is very limited, and these disorders need more attention from mental health professionals in the workplace as well as from employers. Over the last decade, major changes have taken place in the work environment in Japan. More stress and less support from supervisors or colleagues in the workplace have made employees stressed out. The number of employees with mental disorders, including somatoform disorders, taking sick leave has significantly increased. In our multi-centre collaborative study, somatoform disorders were the third most prevalent psychiatric disorder in employees, after mood and schizophrenic disorders. Employees with neurotic disorders manifested physical symptoms more frequently than those without. Young employees frequently reported somatic symptoms such as general malaise, nausea, constipation, diarrhoea, headache, stiff shoulder, and dizziness. A rational new approach is needed to tackle this important psychopathology increasingly seen among employees.

Obsessive–compulsive spectrum of disorders: a defensible construct?

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.

Health anxiety levels in chronic pain clinic attenders

OBJECTIVE

An application of the cognitive-behavioural model of health anxiety (hypochondriasis) to chronic pain depends on the extent to which high levels of health anxiety occur in chronic pain, which has yet to be established.

METHODS

The occurrence of health anxiety in consecutively recruited chronic pain patients (n=161) and nonclinical controls with (n=34) and without pain (n=70) was investigated using a questionnaire measure of health anxiety.

RESULTS

Conservative figures estimated a frequency of 36.7% for hypochondriasis and 51.1% of severe and disabling health anxiety in the chronic pain sample.

CONCLUSION

The current finding that high levels of health anxiety are indeed very common in chronic pain indicates the potential value of an application of the cognitive-behavioural health anxiety model to at least the subgroup of highly health-anxious chronic pain patients.

Measuring anxiety: are we getting what we need?

This article discusses several studies describing either the reevaluation and validation of existing scales for measuring anxiety (i.e., the Spielberger Trait Anxiety Inventory, the Liebowitz Social Anxiety Scale for adults and for children and adolescents, the Clinical Global Impression Scale, the Self-Rating Inventory for Posttraumatic Stress Disorder, and the Yale-Brown Obsessive Compulsive Scale Symptom Checklist), or the development and validation of new scales (i.e., the Social Thoughts and Beliefs Scale, the Social Phobia Diagnostic Questionnaire, the Aberdeen Trauma Screening Index and the Health Anxiety Inventory). As an increasing number of rating scales have been developed over the past several years, a critical review of their usefulness and psychometric properties seems pertinent and prudent.

Time course of depression-symptom improvement during treatment with duloxetine

The aim of this study was to examine the longitudinal response for overall and individual symptoms during the treatment of major depressive disorder. Data were pooled from two 9-week trials, which compared duloxetine 60-mg QD (n=251) with placebo (n=261) in the treatment of MDD. Changes from baseline in the 17-item Hamilton Depression Rating Scale (HAMD17) and in the Visual Analog Scales for pain were analyzed. Compared to placebo-treated patients, duloxetine-treated patients experienced greater improvement (P<.05) in the HAMD17 total score at Week 2. The individual symptoms showing the most rapid improvements (Week 1) were depressed mood, guilt, suicidal ideation, work/activities, and psychic anxiety as well as VAS back pain and shoulder pain. At subsequent visits, significant improvements were observed in retardation (Week 2); hypochondriasis (Week 3); general somatic symptoms (Week 5); middle and late insomnia (Week 7); and gastrointestinal (GI) symptoms, genital symptoms (level of sexual interest or ease of sexual arousal), insight, and early insomnia (Week 9). Significant advantages for duloxetine were not achieved at any visit for agitation, somatic anxiety, or weight loss. At Weeks 1 and 2, placebo-treated patients had significantly lower GI symptoms and reported less weight loss compared with duloxetine-treated patients; however, differences were not significant at subsequent visits. Furthermore, duloxetine was superior to placebo on GI symptoms at endpoint compared to placebo-treated patients; duloxetine-treated patients had a significantly higher response rate at Week 2 and a higher remission rate at Week 5. These results may help clinicians establish more accurate expectations regarding treatment with duloxetine.

Antidepressant treatment outcomes of psychogenic movement disorder

BACKGROUND

Psychogenic movement disorder (PMD) is a subtype of conversion disorder. We describe the outcomes of a series of PMD patients following antidepressant treatment.

METHOD

Twenty-three outpatients with chronic PMD, diagnosed using Fahn and Williams' criteria, underwent psychiatric assessment. The patients were referred for assessment and management from January 2003 to July 2004. Fifteen agreed to be treated with antidepressants. Patients received citalopram or paroxetine; those who did not respond after 4 weeks of taking an optimal dose were switched to venlafaxine. Concurrently, 3 had supportive psychotherapy, and 1 had family intervention. Assessments included the DSM-IV-based Mini-International Neuropsychiatric Interview and scales measuring depression, anxiety, and motor and global severity.

RESULTS

Eighteen patients (78%) had at least 1 Axis I diagnosis in addition to the somatoform diagnosis, and 3 (13%) had somatization disorder. Five (22%) had previous psychiatric contact. Nine (39%) had previously been treated with antidepressants, but only 4 (17%) had adequate trials. No significant differences existed in patient characteristics between treated and untreated groups. Among treated patients, Montgomery-Asberg Depression Rating Scale scores improved from baseline (p < .01). Two treated subgroups were identified: 10 patients (67%) had primary conversion disorder, of whom 8 had marked motor and global improvements with 7 complete remissions, and 5 (33%) had primary hypochondriasis, somatization disorder, or probable factitious disorder/malingering, of whom none improved. All of the patients with primary conversion disorder had a current or previous depressive or anxiety disorder compared with 40% (N = 2) of the patients with additional somatoform diagnoses.

DISCUSSION

Our preliminary findings suggest that chronic PMD with primary conversion symptoms and with recent or current depression or anxiety may respond to antidepressants. Further well-designed studies, now under way, are required to confirm these findings.

Fear of movement/injury in the general population: factor structure and psychometric properties of an adapted version of the Tampa Scale for Kinesiophobia

In recent years, several studies have pointed out the importance of pain-related fear in the development and maintenance of chronic pain. An important instrument for measuring pain-related fear in the context of low back pain is the Tampa Scale for Kinesiophobia (TSK). Recently, a version of this questionnaire has been developed for administration among the general population (TSK-G). To determine the factor structure of the TSK-G, data from a random sample of the Dutch general population were studied separately for people who had had back complaints in the previous year, and people who had been without back complaints. For both groups the TSK-G appeared to consist of one, internally consistent, factor of 12 items. The one-factor TSK-G also appeared valid after comparison with scores on measures of catastrophizing and general health status.

Estudio del grado de aprensión social en usuarios de atención primaria: su relación con la ansiedad y la conducta de enfermedad

OBJECTIVE

To analyse the level of social apprehension in people who use primary care centres and its relationship with their level of anxiety and illness behaviour.

DESIGN

Descriptive, observational, and cross-sectional study.

SETTING

The study was carried out at 3 primary care centres: CAP Sant Miquel, CAP Bellavista, and CAP Vallès Oriental.

PARTICIPANTS

330 subjects aged between 18 and 75 years old who used their primary care Centre and participated voluntarily in the study.

MAIN MEASUREMENTS

A sociodemographic data questionnaire and the following measurements were used: the Social Apprehension Scale (SAS), the State/Trait Anxiety Inventory (STAI), and the Illness Behaviour Questionnaire (IBQ).

RESULTS

31.8% of the subjects showed high levels of social apprehension and 44.5% revealed moderate scores. Statistically meaningful relation was observed between the levels of social apprehension and the levels of trait anxiety (P=.002), state anxiety (P=.008), hypochondriasis (P=.000), affective disturbance (P=.037), disease conviction (P=.001), interpersonal discord (P=.001), and difficulties in social relations (P=.042).

CONCLUSIONS

A high percentage of primary care users show high/moderate levels of social apprehension that are directly linked to anxiety and inversely linked to the concept of abnormal illness behaviour related to hypochondriasis and other fears of suffering from health disorders.

Mental disorders in primary care: prevalence and co-morbidity among disorders. results from the functional illness in primary care (FIP) study

BACKGROUND

Prevalence and co-occurrence of mental disorders is high among patients consulting their family general practitioner (GP) for a new health problem, but data on diagnostics and socio-demographics are sketchy.

METHOD

A cross-sectional two-phase epidemiological study. A total of 1785 consecutive patients with new complaints, aged 18-65 years, consulting 28 family practices during March-April 2000 in Aarhus County, Denmark were screened, in the waiting room, for mental and somatic symptoms with SCL-8 and SCL-Somatization questionnaires, for illness worry with Whitely-7 and for alcohol dependency with CAGE. In a stratified random sample of 701 patients, physician interviewers established ICD-10 diagnoses using the SCAN interview. Prevalence was calculated using weighted logistic regression, thus correcting for sample skewness.

RESULTS

Half of the patients fulfilled criteria for an ICD-10 mental disorders and a third of these for more than one group of disorders. Women had higher prevalence of somatization disorder and overall mental disorders than men. Men had higher prevalence of alcohol abuse and hypochondriasis than women. Psychiatric morbidity tended to increase with age. Prevalence of somatoform disorders was 35.9% (95% CI 30.4-41.9), anxiety disorders 164% (95% CI 12.7-20.9), mood disorders 13.5% (95% CI 11.1-16.3), organic mental disorders 3.1% (95% CI 1.6-5.7) and alcohol abuse 2.2% (95% CI 1.5-3.1). Co-morbidities between these groups were highest for anxiety disorders, where 89% also had another mental diagnosis, and lowest for somatoform disorders with 39%.

CONCLUSIONS

ICD-10 mental disorders are very prevalent in primary care and there is a high co-occurrence between most disorders. Somatoform disorders, however, more often than not exist without other mental disorders.

Differentiating hypochondriasis from panic disorder

Hypochondriasis and panic disorder are both characterized by prevalent health anxieties and illness beliefs. Therefore, the question as to whether they represent distinct nosological entities has been raised. This study examines how clinical characteristics can be used to differentiate both disorders, taking the possibility of mixed symptomatologies (comorbidity) into account. We compared 46 patients with hypochondriasis, 45 with panic disorder, and 21 with comorbid hypochondriasis plus panic disorder. While panic patients had more comorbidity with agoraphobia, hypochondriasis was more closely associated with somatization. Patients with panic disorder were less pathological than hypochondriacal patients on all subscales of the Whiteley Index (WI) and the Illness Attitude Scales (IAS) except for illness behavior. These differences were independent of somatization. Patients with hypochondriasis plus panic had higher levels of anxiety, more somatization, more general psychopathology and a trend towards increased health care utilization. Clinicians were able to distinguish between patient groups based upon the tendency of hypochondriacal patients to demand unnecessary medical treatments. These results confirm that hypochondriasis and panic disorder are distinguishable clinical conditions, characterized by generally more psychopathology and distress in hypochondriasis.

Does personality at college entry predict number of reported pain conditions at mid-life? A longitudinal study

The purpose of this study was to evaluate whether personality traits, as assessed by the Minnesota Multiphasic Personality Inventory (MMPI), at time of college entry can predict the number of reported pain conditions at an approximate 30-year follow-up for 2332 subjects, 1834 men and 498 women, who were administered the MMPI on entry to the University of North Carolina (Chapel Hill) between 1964 and 1966. In 1997, a follow-up was conducted in which subjects were administered a self-report questionnaire regarding whether they had experienced 1 or more chronic pain conditions. Analyses of the relationship between the MMPI clinical scales at college entrance and the report of number of chronic pain conditions at follow-up were conducted. Among male participants, elevations of Scales 1 (Hypochondriasis), 3 (Hysteria), and 5 (Masculinity/Femininity) predicted increases in number of chronic pain conditions at follow-up. For female participants, elevations in Scales 1, 3, and 6 (Paranoia) predicted increases in number of chronic pain conditions at follow-up. The current study suggests that a statistically significant relationship exists between MMPI responses at college entry and reports of chronic pain conditions at mid-life.

PERSPECTIVE

This study found a small, but significant relationship between elevations on MMPI scales measuring hypochondriasis and hysteria and the report of chronic pain conditions at follow-up. The study is important because it is the first to examine how personality assessed in younger adults relates to the number of chronic pain conditions reported 30 years later.

Somatization revisited: diagnosis and perceived causes of common mental disorders

The assessment of somatoform disorders is complicated by persistent theoretical and practical questions of classification and assessment. Critical rethinking of professional concepts of somatization suggests the value of complementary assessment of patients' illness explanatory models of somatoform and other common mental disorders. We undertook this prospective study to assess medically unexplained somatic symptoms and their patient-perceived causes of illness and to show how patients' explanatory models relate to professional diagnoses of common mental disorders and how they may predict the short-term course of illness. Tertiary care patients (N=186) with prominent somatoform symptoms were evaluated with the Structured Clinical Interview for DSM-IV, a locally adapted Explanatory Model Interview to elicit patients' illness experience (priority symptoms) and perceived causes, and clinical self-report questionnaires. The self-report questionnaires were administered at baseline and after 6 months. Diagnostic overlap between somatoform, depressive, and anxiety disorders occurred frequently (79.6%). Patients explained pure somatoform disorders mainly with organic causal attributions; they explained pure depressive and/or anxiety disorders mainly with psychosocial perceived causes, and patients in the diagnostic overlap group typically reported mixed causal attributions. In this last group, among patients with similar levels of symptom severity, organic perceived causes were related to a lower physical health sum score on the MOS Short Form, and psychosocial perceived causes were related to less severe depressive symptoms, assessed with the Hospital Anxiety and Depression Scale at 6 months. Among patients meeting criteria for comorbid somatoform with anxiety and/or depressive disorders, complementary assessment of patient-perceived causes, a key element of illness explanatory models, was related to levels of functional impairment and short-term prognosis. For such patients, causal attributions may be particularly useful to clarify clinically significant features of common mental disorders and thereby contribute to clinical assessment.

[Clinical variants of hypochondriac state in patients with duodenal ulcer]

AIM

To describe some clinical variants of hypochondriac syndrome in patients with duodenal ulcer (DU).

MATERIAL AND METHODS

A hypochondriac trend was studied clinically and was confirmed by changes in the first scale of AMPI in 150 DU patients. If the first scale contained a rise over 70 points, the examinee was stated to be much concerned about his/her health.

RESULTS

Hypochondriac syndrome in exacerbation was registered in 59 (39.3%) patients. It was accompanied with anxiety in 28.8% cases. Introversion and original attitude to somatic disorders were observed in 25.4% cases. Demonstrative behavior was seen in 23.8% patients. Depressive trends occurred in 13.5% patients. Conception of the disease was confirmed in 5.1% cases. Hypochondriac state with protest reactions and hyperthymic effect occurred least frequently (1 and 1 case, respectively).

CONCLUSION

Hypochondriac states aggravate DU, deteriorate quality of life. Early diagnosis of a variant of hypochondriac syndrome enables a directed individual psychotherapy which improves emotional state of the patient and prevent further development of psychopathological traits.

Respiratory symptoms and mental disorders among youth: results from a prospective, longitudinal study

OBJECTIVE

To determine the relationship between respiratory symptoms and mental disorders among youth in the community, and to investigate possible mechanisms of these linkages.

METHODS

Data were drawn from the Oregon Adolescent Depression Project (n = 1,709), a longitudinal study of adolescents in the community. Multiple logistic regression analyses were used to examine the cross-sectional and longitudinal associations between respiratory symptoms and mental disorders at baseline, and linkages between respiratory symptoms at baseline and the onset of specific mental disorders at follow-up. Additional analyses were performed to examine the strength and specificity of the relationship between respiratory symptoms and mental disorders. The potential roles of hypochondriasis, functional impairment, and cigarette smoking in the associations between respiratory symptoms and mental disorders were investigated.

RESULTS

Respiratory symptoms were associated with a significantly increased odds of any mental disorder (odds ratio (OR) = 1.9), specifically any depressive disorder (OR = 1.9), major depression (OR = 1.9), any substance use disorders (OR = 1.6), panic attacks (OR = 3.1), and attention deficit/hyperactivity disorder (ADHD) (OR = 5.8) at baseline. Respiratory symptoms at between 1987 and 1989 (Time 1) were associated with significantly increased risk of the onset of any mental disorder a year later (Time 2) (OR = 2.1). While demographic differences, hypochondriasis, functional impairment, and cigarette smoking contributed to the relationships between respiratory symptoms and mental disorders, these associations persisted after adjusting for these factors.

CONCLUSIONS

The results suggest evidence of an association between respiratory symptoms and mental disorders among youth in the community. While demographic differences, hypochondriasis, functional impairment, and cigarette smoking may contribute to the linkage, these factors do not appear to completely explain the association. Future studies that can replicate these findings and include an examination of other possible mechanisms for these patterns of comorbidity, such as shared familial vulnerability or other environmental risk factors (e.g., childhood behavioral risk factors), are needed next.

Somatoforme Beschwerden bei �lteren Menschen

The aim of this study is to determine the prevalence of clinically relevant somatoform complaints in a representative sample of the elderly. For the first time, the job-related development of the elderly is analysed in relation to somatoform complaints. Further, personality variables and family development are examined. The data basis of the evaluation is a partial sample (n = 1002) of the cohort study "Interdisziplinäre Längsschnittstudie des Erwachsenenalters" (ILSE). The assessment included a half-structured interview on the development of work and family, a detailed clinical examination, a psychiatric screening (SCID) and the neuroticism and extraversion scales of the personality test NEO-FFI. A total of 29 participants (2.9%) with clinically relevant somatoform complaints were identified, 20 females and 9 males. They were significantly less satisfied and less involved in their careers than the rest of the sample. They evaluated their partnership as significantly worse, yet the amount of experienced distress did not differ. The index group scored much higher on scales for neuroticism than the other, whereas they scored significantly lower on scales for extraversion.

Recognizing and treating uncommon behavioral and emotional disorders in children and adolescents who have been severely maltreated: somatization and other somatoform disorders

This article reviews current knowledge about somatoform disorders in children and adolescents. Somatoform disorders are likely to occur more frequently in children and adolescents who have been severely maltreated than in others. The symptoms of somatoform disorders are reviewed, strategies for distinguishing somatoform disorders from other disorders are examined, and treatment strategies are explored.

Profile of mental disorders among the elderly United Arab Emirates population: sociodemographic correlates

OBJECTIVES

To investigate the prevalence, nature and sociodemographic correlates of mental disorders among the elderly United Arab Emirates (UAE) population. STUDY SUBJECTS AND SAMPLE: UAE nationals aged 60 years or more, were recruited from within a random sample of households representing the UAE national population, irrespective of the age of individuals in each household. RESEARCH INSTRUMENTS: (i) Geriatric Mental State Interview (GMS-A3): an Arabic version, using the AGECAT for analysis; (ii) A short questionnaire for relevant sociodemographic data.

PROCEDURE

Purposely trained, Arabic speaking interviewers visited the targeted sample households to interview study subjects at their homes.

RESULTS

The total number of screened subjects was 610: 166 (27.2%) in Al-Ain; 286 (46.9%) in Dubai and 158 (25.9%) in Ras Al-Khaimah. There were 347 (56.9%) male subjects and 263 (43.1%) female subjects. The mean age of the interviewed subjects was 68.6 (SD 8.3). The commonest diagnostic entities at the AGECAT syndrome case level were depression (20.2%), anxiety (5.6%), hypochondriasis (4.4%) and organic, mostly cognitive impairment with or without dementia (3.6%). Organic syndrome caseness, as an independent entity, showed significant correlation only to older age, while the rest of the mental disorders showed significant correlation with female gender, insufficient income and being single, separated, divorced or widowed.

CONCLUSION

The GMS-AGECAT package proved to be a useful tool for psychiatric assessment among the elderly in this Arabian culture. The prevalence rates of mental disorders among the elderly UAE population were, more or less, within the same range reported by other comparable worldwide studies.

High utilizers of medical care: a crucial subgroup among somatizing patients

OBJECTIVE

Patients with somatoform disorders (SFD) are likely to overutilize healthcare services. This study investigates (a) whether extraordinarily high medical costs can be predicted from patient characteristics or psychopathology, and (b) whether high-utilizing patients respond differently to cognitive-behavioral treatment.

METHODS

We compared 42 SFD high utilizers with 53 SFD average utilizers and 29 patients suffering from other than SFD mental disorders. High utilization was defined by healthcare expenditures of > or = 2500 euros during the past 2 years. Costs were computed from medical and billing records of health insurance companies. Somatization distress, hypochondriasis, depression, dysfunctional cognitions related to bodily symptoms, general psychopathology, personality profiles, and psychosocial disabilities were assessed before treatment.

RESULTS

High utilizers had higher levels of self- and observer-rated illness behavior, self-perceived bodily weakness, and psychosocial disabilities. Although they did not report more somatization symptoms, their subjective symptom distress was higher. There were no differences between high and average utilizers concerning general psychopathology, DSM-IV comorbidity, and personality profiles. Treatment improvements were similar.

CONCLUSION

High- and average-utilizing somatizers represent distinguishable subgroups. The results emphasize the importance of mechanisms specifically related to SFD and may enhance the early detection of patients who are likely to develop overutilization.

Personality as a predictor of hypochondriacal concerns: results from two longitudinal studies

OBJECTIVES

To explore the extent to which the domains of the Big 5 are risk factors for hypochondriacal concerns (HCs).

METHODS

Two longitudinal studies, one using blood donors (over a 16-17-month period) and one using undergraduate students (over a 2.5-month period), were used to collect data on the Big 5 and HCs.

RESULTS

Univariate analyses indicated that: (1) emotional stability predicted future levels of HCs once baseline levels of HCs were controlled, and (2) reductions in HCs over time were predicted primarily by increases in conscientiousness and emotional stability scores. Structural modelling of cross-lagged effects indicated that emotional stability was related to future levels of hypochondriacal concerns by contributing to initial levels of HCs. Regression analysis indicated that those who become more conscientious become less health anxious.

CONCLUSIONS

Emotional stability and conscientiousness have predictive roles with respect to HCs.

Factor structure of the Psychiatric Diagnostic Screening Questionnaire (PDSQ), a screening questionnaire for DSM-IV axis I disorders

We examined the factor structure of the Psychiatric Diagnostic Screening Questionnaire (PDSQ), a 125-item self-report scale that screens for 15 of the most common Axis I psychiatric disorders for which patients seek treatment in outpatient settings. The sample consisted of 2440 psychiatric outpatients. Thirteen factors were extracted. Ten mapped directly onto the DSM-IV diagnosis for which they were designed and one represented suicidal ideation. The remaining two factors reflected closely related disorders: Panic Disorder/Agoraphobia, and Somatization/Hypochondriasis. A psychosis factor was not extracted. Overall, the factor structure of the PDSQ was consistent with the DSM-IV nosology upon which it was developed.

The relationship of obsessive-compulsive disorder to putative spectrum disorders: results from an Indian study

The relationship between obsessive-compulsive disorder (OCD) and putative obsessive-compulsive (OC) spectrum disorders is unclear. This study investigates the prevalence of putative OC spectrum disorders in OCD subjects in a controlled clinical design. The putative OC spectrum disorders studied included somatoform disorders (body dysmorphic disorder [BDD] and hypochondriasis), eating disorders, tic disorders (e.g., Tourette's syndrome [TS]), and impulse control disorders (e.g., trichotillomania). Only those disorders that are commonly noted to be possibly related to OCD are studied. Included in this study were 231 subjects with a diagnosis of OCD according to DSM-IV criteria and 200 controls who were not screened for psychiatric morbidity. The subjects and controls were assessed in detail by extensive clinical and semistructured interviews by expert clinical psychiatrists. The lifetime diagnoses were made by consensus of two psychiatrists. Prevalence of tic disorders, hypochondriasis, BDD, and trichotillomania was significantly greater in OCD subjects compared to controls. However, the prevalence of sexual compulsions, pathological gambling, eating disorders, and depersonalization disorder was not greater in the OCD subjects compared to controls. The findings of this comorbidity study suggest that tic disorders, hypochondriasis, BDD, and trichotillomania are perhaps part of the OC spectrum disorders. There is a need to evaluate evidence from other sources such as epidemiological, neurobiological, and family studies to further our understanding of the concept of OC spectrum disorders.

An open trial of fluvoxamine for hypochondriasis

The authors conducted a 12-week, open-label trial of fluvoxamine among 18 patients with DSM-IV hypochondriasis. Response was defined as a physician-rated CGI improvement rating of at least "much improved." Four patients discontinued during the 2-week placebo run-in phase. Among 14 patients given fluvoxamine, the response rate was 72.7% (N=8 of 11) for those completing at least 6 weeks of the trial (minimum-treatment analysis) and 57.1% (N=8 of 14) for the intent-to-treat analysis; these are comparable to rates reported previously for fluoxetine. Significant improvement was also noted on each of the self-report and physician-administered hypochondriasis measures. Fluvoxamine was also well tolerated. A controlled trial is needed.

Somatization among older primary care attenders

BACKGROUND

The importance of somatization among older primary care attenders is unclear. We aimed to establish the prevalence, persistence and associations of somatization among older primary care attenders, and the associations of frequent attendance.

METHOD

One hundred and forty primary care attenders over 65 years were rated twice, 10 months apart, on measures of somatization, psychiatric status, physical health and attendance.

RESULTS

The syndrome of GMS hypochondriacal neurosis had a prevalence of 5% but was transient. Somatized symptoms and attributions were persistent and associated with depression, physical illness and perceived poor social support. Frequent attenders (top third) had higher rates of depression, physical illness and somatic symptoms, and lower perceived support.

CONCLUSION

Somatization is common among older primary care attenders and has similar correlates to younger primary care somatizers. Psychological distress among older primary care attenders is associated with frequent attendance. Improved recognition should result in benefits to patients and services.

The identification of OCD-related subgroups based on comorbidity

BACKGROUND

Individuals with obsessive-compulsive disorder (OCD) frequently have other psychiatric disorders. This study employed latent class analysis (LCA) to explore whether there are underlying clinical constructs that distinguish "OCD-related" subgroups.

METHODS

The study included 450 subjects, case and control probands and their first-degree relatives, and LCA was used to derive empirically based subgroups of 10 disorders: OCD, obsessive-compulsive personality disorder (OCPD), recurrent major depressive disorder (RMDD), separation anxiety disorder, panic disorder or agoraphobia (PD/AG), tic disorders (TD), generalized anxiety disorder (GAD), somatoform disorders (hypochondriasis or body dysmorphic disorder), pathologic skin picking or nail biting (PSP/NB), and eating disorders (EDs). The derived classes were compared on several clinical variables.

RESULTS

The best fitting model is a four-class structure: minimal disorder, predominant RMDD and GAD, "highly comorbid," and PD/AG and TD. The nature and number of disorders represented suggests that the first classes are distributed ordinarily on a dimension of severity, and the fourth class is qualitatively distinct. Support for this structure is based on the number of disorders, age at onset of OCD, neuroticism, and extraversion.

CONCLUSIONS

In this OCD enriched sample, LCA identified four classes of disorder. These classes appear to conform to two subgroups that may prove useful in investigating the etiology of OCD.

Predictors of somatic symptoms in depressive disorder

We explored the relative contribution of potential psychological predictors of somatic symptoms in outpatients with major depressive disorder, including; 1) severity of depression; 2) general anxiety; 3) hypochondriacal worry; 4) somatosensory amplification; and, 5) alexithymia by sampling 100 consecutive outpatients with DSM-IV diagnoses of major depressive disorder attending the psychiatry clinics of general hospitals in Turkey. The subjects were rated by clinicians on depressive symptomatology (Hamilton Depression Rating Scale), and anxiety (Hamilton Anxiety Scale), and completed self-report measures of Hypochondriacal worry (7-item version of the Whiteley Index), the Somatosensory Amplification Scale, and the Toronto Alexithymia Scale. Multivariate models tested the independent contribution of each of the scales to the level of somatic symptoms as measured by a modified version of the SCL-90 somatization scale. At the bivariate level, somatic symptoms were associated with female gender and lower educational level, as well as the Hamilton Depression and Anxiety scales, the Whitely Index, and the Somatosensory Amplification and Alexithymia scales. In multiple regression models incorporating all variables, female gender and higher scores on the anxiety, somatosensory amplification and alexithymia scales all made independent contributions to the level of somatic symptoms and accounted for 54% of the variance. Therefore, somatic symptoms in depression are related to concomitant anxiety, tendency to amplify somatic distress, and difficulty identifying and communicating emotional distress. However, these factors do not account for the tendency for women to report more somatic symptoms.
