Palpitations, cardiac awareness, and panic disorder.

This article reviews and appraises a variety of studies on panic disorder, visceral sensitivity, and cardiac disease. The literature reviewed includes descriptive surveys, small-scale experimental manipulations, and clinical interventions. Instruments have included structured diagnostic interviews, clinical observation, self-report inventories, direct measures of perceptual sensitivity, and cognitive tests. The subjects in these studies have ranged from community residents to carefully defined samples of designated patients with psychiatric or cardiac disease. We then outline a prospective investigation to examine the prominence of palpitations in panic anxiety and speculate on the importance of sensitivity to cardiac sensation in several other clinical conditions characterized by marked discrepancies between cardiac activity and cardiac symptoms.

Psychiatric comorbidity in DSM-III-R hypochondriasis.

Forty-two DSM-III-R hypochondriacs from a general medical clinic were compared with a random sample of 76 outpatients from the same setting. Patients completed a research battery that included a structured diagnostic interview (Diagnostic Interview Schedule) and self-report questionnaires to measure personality disorder caseness, functional impairment, and hypochondriacal symptoms. Psychiatric morbidity in the hypochondriacal sample significantly exceeded that of the comparison sample. Hypochondriacs had twice as many lifetime Axis I diagnoses, twice as many Diagnostic Interview Schedule symptoms, and three times the level of personality disorder caseness as the comparison group. Of the hypochondriacal sample, 88% had one or more additional Axis I disorders, the overlap being greatest with depressive and anxiety disorders. One fifth of the hypochondriacs had somatization disorder, but the two conditions appeared to be phenomenologically distinct. Hypochondriacal patients with coexisting anxiety and/or depressive disorder (secondary hypochondriasis) did not differ greatly from hypochondriacal patients without these comorbid conditions (primary hypochondriasis). Because the nature of hypochondriasis remains unclear and requires further study, we suggest that its nosologic status not be altered in DSM-IV.

Determinants of perceived health status of medical outpatients.

The aim of this study was to examine the relative contributions made by medical morbidity, psychiatric disorder, functional status, and hypochondriacal attitudes to medical patients' opinions of their overall health status. The study was conducted in the general medical clinic of a large academic teaching hospital. Consecutive clinic visitors on randomly selected days were screened with a hypochondriasis self-report questionnaire, since the overall project was designed as a study of hypochondriasis. A random sample of the patients below a pre-established cutoff (n = 100), along with all those exceeding the cutoff (n = 88), returned to undergo a research battery. For this analysis, a representative sample of the entire clinic was reconstituted by weighting the data from patients above and below the screening cutoff in proportion to their prevalence in the clinic. Measures of psychiatric disorder (the Diagnostic Interview Schedule), personality disorder, functional status and disability, medical morbidity (from physician ratings and medical record audit), and hypochondriacal attitudes were obtained. Patient self-ratings of global health status were significantly correlated with aggregate medical morbidity (r = 0.36; P less than 0.001); psychiatric morbidity (r = 0.48; P less than 0.001); functional disability (for intermediate activities of daily living, r = 0.62; P less than 0.001); hypochondriacal attitudes (r = 0.79; P less than 0.001); and with the tendency to somatize (r = 0.77; P less than 0.001). Using multiple regression analysis, the most powerful correlates of perceived global health were hypochondriasis, somatization and disability (model R2 = 0.762).(ABSTRACT TRUNCATED AT 250 WORDS)

A structured diagnostic interview for hypochondriasis. A proposed criterion standard.

We developed a structured diagnostic interview for DSM-III-R hypochondriasis (SDIH) that is the first such clinician-administered instrument. The SDIH was administered to 88 general medical outpatients who scored above a predetermined cutoff on a hypochondriacal symptom questionnaire, and to 100 comparison patients randomly chosen from among those below the cutoff. Using the joint assessment method, interrater agreement on the DSM-III-R diagnostic criteria was 88% to 97% and agreement on the diagnosis was 96%. Concurrent validity was suggested by a significant correlation between the interview and the primary care physicians' ratings of hypochondriasis. A measure of external validity was demonstrated in that several clinical characteristics thought to be ancillary features of hypochondriasis were significantly more prevalent in interview-positive patients than in interview-negative patients. Finally, the SDIH appeared to have discriminant validity in that patients diagnosed as hypochondriacal had several other clinical features that distinguished them from the patients who scored above the cutoff on hypochondriacal symptomatology, but failed to be diagnosed as hypochondriacal with the SDIH.

Hypochondriasis and obsessive compulsive disorder.

Hypochondriasis and OCD differ conceptually in the degree to which the patient's disease concerns are experienced as an intrusive mental event or a reasonable psychological response to a realistic health threat, in the degree to which the ideation is resisted, and in the presence of somatic sensations and medical help-seeking. There are, however, some similarities between the conditions, including the development of excessive, stereotyped, repetitive behaviors in an attempt to allay their anxiety. Empirical data on the degree of overlap between the conditions are too limited to permit definitive conclusions. The little that we do know, however, suggests that (1) the prevalence of OCD in hypochondriasis is probably elevated, but not extraordinarily so; (2) the prevalence of hypochondriasis in OCD is unknown; (3) fears about disease, illness, and injury are one of the more common forms of obsessions seen in OCD; and (4) there are several ill-defined and largely unexplored conditions, such as disease phobias, which appear to be very similar to both OCD and hypochondriasis. Clinical experience suggests that there may be a subgroup of hypochondriacal patients who are closer to the anxiety disorders in general and to OCD in particular. This subgroup might respond to the newer, antiobsessional, serotonin reuptake blocking agents.

Performance of a five-item mental health screening test.

We compared the screening accuracy of a short, five-item version of the Mental Health Inventory (MHI-5) with that of the 18-item MHI, the 30-item version of the General Health Questionnaire (GHQ-30), and a 28-item Somatic Symptom Inventory (SSI-28). Subjects were newly enrolled members of a health maintenance organization (HMO), and the criterion diagnoses were those found through use of the Diagnostic Interview Schedule (DIS) in a stratified sample of respondents to an initial, mailed GHQ. To compare questionnaires, we used receiver operating characteristic analysis, comparing areas under curves through the method of Hanley and McNeil. The MHI-5 was as good as the MHI-18 and the GHQ-30, and better than the SSI-28, for detecting most significant DIS disorders, including major depression, affective disorders generally, and anxiety disorders. Areas under curve for the MHI-5 ranged from 0.739 (for anxiety disorders) to 0.892 (for major depression). Single items from the MHI also performed well. In this population, short screening questionnaires, and even single items, may detect the majority of people with DIS disorders while incurring acceptably low false-positive rates. Perhaps such extremely short questionnaires could more commonly reach use in actual practice than the longer versions have so far, permitting earlier assessment and more appropriate treatment of psychiatrically troubled patients in primary care settings.

Comparison of psychiatric screening tests in a general medical setting using ROC analysis.

Receiver operating characteristic (ROC) analysis was used to evaluate the usefulness of three self-administered screening instruments in helping primary care physicians detect anxiety and depressive disorders. This research was secondary to an investigation of hypochondriasis. The three tests were the Whitely Index (WI), the Somatosensory Amplification Scale (SAS), and the Somatic Symptom Inventory (SSI). Participating subjects were 75 patients seen in a general medical clinic and diagnosed as being free of hypochondriasis by DSM-III-R criteria. Psychiatric disorder was assessed with the Diagnostic Interview Schedule, version III-A. The three instruments delineated patients with depressive disorders versus no depressive disorders and patients with anxiety disorders versus no anxiety disorders. For depressive disorder, the areas under the curve (AUC) were 0.87, 0.75, and 0.82 for the WI, SAS, and SSI, respectively. For anxiety disorders the AUCs were 0.79, 0.76, and 0.74, respectively, for the three tests. Although the WI yielded slightly higher values, the areas under the ROC curves did not differ significantly among the three tests. Because of its relatively short length--13 items--it was concluded that the WI can be useful for screening primary care patients, both with respect to depressive and anxiety disorders.

The relation between hypochondriasis and age.

OBJECTIVE: This study examined the relation between hypochondriasis and age while controlling for the possible confounding influences of medical morbidity, social isolation, and other psychiatric disorder. METHOD: Consecutive patients attending a general medical clinic on randomly selected days were screened with a hypochondriasis self-report questionnaire. Those whose scores exceeded a preestablished cutoff level and a random sample of those who scored below it completed a research battery consisting of self-report questionnaires and structured interviews for DSM-III-R diagnoses of hypochondriasis and other axis I disorders. The patients' medical records were audited, and their physicians completed questionnaires about them. The 60 patients who met the DSM-III-R criteria for hypochondriasis at interview constituted the study group, and 100 patients randomly chosen from among those who scored below the cutoff for hypochondriasis constituted the comparison group. RESULTS: The hypochondriacal group was not older than the comparison group. Hypochondriacal patients aged 65 years and over did not differ significantly from younger hypochondriacal patients in hypochondriacal attitudes, somatization, tendency to amplify bodily sensation, or global assessment of their overall health, even though their aggregate medical morbidity was greater. The elderly hypochondriacal patients had higher levels of disability, but this appeared to be attributable to their medical status rather than to any increase in hypochondriasis. Within the comparison sample, subjects aged 65 years and over were not more hypochondriacal than those under 65 years of age. CONCLUSIONS: Hypochondriasis is found to some degree in all patients and appears to be unrelated to age.

The relationship between hypochondriasis and medical illness.

Forty-one Diagnostic and Statistical Manual of Mental Disorders-III-Revised hypochondriacs were accrued from a primary care practice. Seventy-five control subjects were selected at random from among the remainder of the patients in the same clinic. All subjects completed a structured diagnostic interview and standardized self-report questionnaires. Medical morbidity was assessed with a medical record audit and with primary physicians' ratings. The hypochondriacal and comparison samples did not differ in aggregate medical morbidity, although the hypochondriacal sample had more undiagnosed complaints and nonspecific findings in their medical records. Within the comparison sample, higher levels of medical morbidity were associated with higher levels of hypochondriacal symptoms. This occurred primarily because the most serious medical disorders were associated with more bodily preoccupation, disease conviction, and somatization. Within the hypochondriacal sample, no correlation was found between the degree of hypochondriasis and the extent of medical morbidity.

Silent myocardial ischemia. Is the person or the event silent?

The symptoms of organic disease vary widely among patients with the same tissue abnormality, because the experience of a symptom is shaped by the patient's perceptual and cognitive style. Thus, the relationship between myocardial ischemia and chest pain is variable in that many patients experience pain without ischemia and many others exhibit ischemia without pain-termed "silent" or "asymptomatic ischemia." Although the nature of the ischemic event may be important in determining the degree of associated pain, we suggest more study of the individual who perceives the event. Myocardial ischemia may not generate a spontaneous report of chest pain because the patient is generally hyposensitive to visceral sensation; because he or she is coping with the threat of heart disease by denying the evidence of it--ie, denying the pain to deny the disease; or because the patient misunderstands the cause and significance of a vague or ambiguous cardiac sensation, normalizing the symptom and misattributing it to a nonpathologic cause.

Transient hypochondriasis.

Consecutive visitors to a general medicine outpatient clinic were screened with a hypochondriasis questionnaire. Two thirds (n = 41) of those exceeding a preestablished cutoff met the criteria for DSM-III-R hypochondriasis when given a structured diagnostic interview, while the other third (n = 22) did not. The latter group showed significant decreases in their hypochondriasis questionnaire scores over a 3-week interval. They had less psychiatric disorder and more medical morbidity than the DSM-III-R hypochondriacs. They also viewed their medical care more positively, and their physicians considered them less hypochondriacal. The transiently hypochondriacal group was also compared with a random sample (n = 75) of the patients below the cutoff on the screening instrument. They had more Axis I disorder, more personality disorder, reported higher levels of somatosensory amplification, and more medical disorder. The differences in psychiatric comorbidity and amplification persist when medical morbidity is controlled for by matching and analysis of covariance. This is consistent with the hypotheses that among patients confronted with a medical illness, those with personality disorder and those who are sensitive to somatic sensation are more likely to develop transient hypochondriasis.

The prevalence of hypochondriasis in medical outpatients.

Forty-one DSM-III-R hypochondriacs were obtained by screening consecutive visitors to a general medical clinic and compared with 76 patients randomly chosen from the same setting. They completed a research battery consisting of a structured diagnostic interview (DIS) and self-report questionnaires to measure hypochondriacal symptoms and functional impairment. The criterion standard for diagnosing hypochondriasis was a structured interview of demonstrated reliability and validity. The six-month prevalence of DSM-III-R hypochondriasis was estimated to be between 4.2% and 6.3% of consecutive attenders who met the inclusion criterion of having visited the same physician before. This rate was somewhat lower than that found for generalized anxiety disorder and comparable to that of alcohol abuse. The hypochondriacal patients did not differ significantly from the comparison random sample in sociodemographic risk factors except that they were significantly more likely to be Black. Hypochondriacal symptomatology was similar in males and females; and in those over 65 and those under 65. Over a three-week interval, hypochondriacal symptoms remained stable, and hypochondriacal patients had significantly higher levels of long-term disability than did the comparison patients.

The somatosensory amplification scale and its relationship to hypochondriasis.

Forty-one DSM-III-R hypochondriacs and seventy-five randomly chosen patients were obtained from a medical outpatient clinic, and completed a psychiatric diagnostic interview and a ten-item self-report questionnaire, the Somatosensory Amplification Scale (SSAS); The SSAS asks the respondent how much s/he is bothered by various uncomfortable visceral and somatic sensations, most of which are not the pathological symptoms of serious diseases. SSAS scores were normally distributed, and had acceptable test-retest reliability and internal consistency. They were not related to sociodemographic characteristics, or to aggregate medical morbidity. Amplification was significantly higher in the DSM-III-R hypochondriacs than in the comparison sample, and was significantly correlated with the degree of hypochondriacal symptomatology within each sample. In the comparison sample, it was also significantly associated with depressive and anxiety disorders, but not with antisocial personality or substance abuse. The association between the amplification scale and DSM-III-R hypochondriasis remained highly significant after controlling for these concurrent psychiatric disorders.

Hypochondriasis and somatosensory amplification.

A self-report questionnaire completed by 177 out-patients showed that hypochondriasis and amplification had a zero-order correlation of 0.56, and in stepwise multiple regression amplification accounted for 31% of the variance in hypochondriasis, after sociodemographic variables had been accounted for. Fears of ageing and death, and a childhood history of illness in the family, increased the R2 to 0.50. Amplification was more powerful in women than in men and was also a significant (although weaker) correlate of somatisation, explaining 12% of the variance. Somatisation also correlated with being female, the propensity to seek medical care, and a diminished sense of efficacy over one's health. Our findings are consistent with the possibility that somatosensory amplification occurs in hypochondriasis.

Hypochondriasis and related health attitudes.

Since hypochondriasis can be thought of as a complex of health attitudes, bodily concerns, and beliefs about disease, it is logical to ask what other attitudes, values, and beliefs might be related to it. By means of self-report questionnaires, the authors studied hypochondriasis, the tendency to amplify somatic sensations, and a series of health-related attitudes and concerns in a random sample of 177 outpatients at a general medicine clinic. Hypochondriasis was positively related to amplification, to fears of aging and death, to the importance placed on health, to a sense of bodily vulnerability to illness and injury, and to the importance placed on one's physical appearance. Cluster analysis disclosed three discrete clusters of patients with distinct profiles on these variables.

A comparison of three psychiatric screening tests using receiver operating characteristic (ROC) analysis.

Self-administered screening questionnaires are available to assist primary care physicians in detecting undiagnosed depression and anxiety disorders. This study used receiver operating characteristic (ROC) analysis to evaluate three such tests: the General Health Questionnaire (GHQ), the Mental Health Inventory (MHI), and the Somatic Symptom Inventory (SSI). Stratified by the results of a preliminary GHQ, 364 health maintenance organization (HMO) members were given these tests and a Diagnostic Interview Schedule (DIS), the latter used as a "truth" standard for current psychiatric diagnosis. The MHI performed significantly better than the GHQ in detecting mental disorders generally and anxiety disorders in particular, and somewhat better in detecting affective disorders. The SSI performed best in detecting anxiety disorders and was significantly better than the GHQ. When subjects who had participated in a previous study involving repeated GHQ administration were excluded, sensitivity of all tests improved, especially the GHQ. We conclude that the MHI can be a useful tool for screening primary care patients, and that the SSI has additional predictive value with respect to anxiety disorders.
