Modern health worries in medical students.

OBJECTIVE: The aim of this study was to investigate the association between modern health worries (MHW), subjective health complaints, and use of health care services in first-year Dutch medical students, and to compare MHW in Dutch and New Zealand cohorts. METHODS: Two hundred and twenty-seven Dutch first-year medical students completed questionnaires assessing MHW, subjective health complaints, positive and negative affect (PA and NA, respectively), and use of health care services. RESULTS: Dutch medical students were most concerned about drug resistant bacteria and least concerned about vaccination programmes. Overall, female students were more concerned about modern health issues than were male students. Students' scores on the MHW scale were significantly associated with subjective health complaints. Subjective health complaints were also significantly related to the use of health care services. The factor structure of the MHW scale was replicated. Respondents reported significantly lower scores on all MHW items than did New Zealand students. CONCLUSIONS: Worries about modernity are reliably associated with subjective health complaints and use of health care services in Dutch medical students.

[Effects and cost-effectiveness analysis of inpatient treatment for somatoform disorders].

Patients with somatoform disorders represent an expensive problem group of the healthcare system characterized by inappropriately high medical costs. This paper describes a controlled inpatient treatment study using a cognitive-behavioral approach. The aim of this treatment program was to improve the patients' symptomatology and their psychosocial functioning, as well as reducing unnecessary medical costs. We treated 172 patients with somatoform disorders (DSM-IV) and compared them with 262 patients of a waiting control list. An additional control group consisted of 123 patients with other mental disorders. Direct and indirect illness-related costs for the two-year periods before and after treatment were re-calculated using objective data provided by the health insurance companies. The results show a marked improvement in the areas of bodily complaints, health anxieties, dysfunctional beliefs towards body and health, depression and psychosocial impairments. The medical costs in the post-treatment period decreased by 1,098 euro (-36.7 %) for inpatient and 382 euro (-24.5 %) for outpatient treatments. Indirect costs due to days lost from work were 6,702 euro (-35.3 %) lower than during the two-years before treatment. The treatment costs had amortized after 21.5 months. We identified a subgroup of high-utilizing somatoform patients for which per patient savings of 32,174 euro (-63.9 %) were found. These results confirm that the cognitive-behavioral approach is effective in improving complaints as well as reducing the health-economical burden of somatoform disorders.

Dimensional and categorical approaches to hypochondriasis.

BACKGROUND: The DSM-IV definition of hypochondriasis is contrasted with hypochondriacal dimensions as provided by the Whiteley Index (WI) and Illness Attitude Scales (IAS). METHODS: Exploratory factor analysis was conducted on self-report data from 570 patients with mental and psychophysiological disorders. Of these, 319 were additionally diagnosed according to DSM-IV by structured interviews. RESULTS: The three 'classic' factors of the WI labelled disease phobia, somatic symptoms and disease conviction were confirmed. The IAS consisted of two dimensions indicating health anxiety and illness behaviour. The overall scores of both instruments were highly correlated (0.80). Optimal cut-off points for case identification yielded sensitivity/specificity rates of 71/80% (WI) and 72/79% (IAS). The IAS was superior to the WI when patients with hypochondriacal disorder were to be discriminated from non-hypochondriacal somatizers. Largest group differences were found for scales related to affective components (health anxieties), smallest for illness behaviours. Affective components of hypochondriasis explained more variance of diagnostic group membership than somatization symptoms. The subscales of disease phobia (WI) and health anxiety (IAS) were most sensitive to treatment-related changes. CONCLUSIONS: The self-rating scales are valid for screening, case definition and dimensional assessment of hypochondriacal disorder, including the differentiation between hypochondriasis and somatization. The existence of distinguishable affective and cognitive components was confirmed.

Immunological differences between patients with major depression and somatization syndrome.

There is some evidence that major depression is accompanied by activation of the inflammatory response system (IRS). There is also evidence that proinflammatory cytokines and induction of IRS activation are associated with sickness behavior in experimental animals. However, no research has examined the IRS in somatization disorder. The aim of this study was to examine possible immunological differences between major depression, somatization and healthy controls. We measured the following IRS variables in patients with major depression (n=36), somatization syndrome (SSI-8; n=37), major depression and somatization (n=40) and healthy controls (n=37): interleukin-6 (IL-6); interleukin-1-receptor-antagonist (IL-1RA); plasma soluble interleukin-6 receptor (IL-6R); soluble suppressor/cytotoxic antigen (CD8); leukemia inhibitory factor (LIF-R); and Clara cell protein (CC16), an endogenous anticytokine. Serum CD8 concentrations were significantly increased in patients with major depression compared with concentrations in patients with somatization syndrome, whereas concentrations in normal controls were intermediate between those of the two groups of patients. Serum CC16 was significantly lower in major depression than in healthy controls. The highest CC16 scores were found in patients with somatization syndrome. Somatizing patients have significantly lower serum IL-6 values than normal controls and depressed patients. The present results indicate (1) an activation of the IRS in depression with signs of T-cell activation (increased CD8), monocytic activation (IL-1RA) and a lowered anti-inflammatory capacity of the serum (lower CC16) and (2) an immune alteration in somatizing syndrome, such as monocytic activation (increased IL-1RA) and indicators of lowered T-lymphocytic activity (lowered CD8 and IL-6). These results suggest different immune alterations in somatization syndrome and depression.

[Diagnosis and treatment of somatoform disorders (functional physical complaints)].

In modern classification systems, unexplained physical symptoms without an organic origin are labelled "somatoform disorders". This syndrome is very frequent and causes a lot of treatment costs as well as indirect costs (such as workers' compensation and others). In the past, effective treatment strategies were lacking. However, consideration of modern scientific results has made it possible to develop treatment approaches which find the acceptance of the patients and which are highly effective. A hierarchical approach is presented suggesting the following steps: a) Primary care: The consideration of management rules in primary care can prevent the chronicity of somatoform symptoms. b) Brief psychological and psychopharmacological treatments: Modern cognitive-behavioural approaches can help to cope with the symptoms and to improve the subjective well-being. First results for pharmacological treatments are encouraging. c) Integrative inpatient treatment including intense psychotherapeutic and psychosomatic ingredients. Experts' judgements of course and prognosis in somatoform disorders should consider the following features: Duration and multiplicity of the complaints; comorbidity with other psychiatric and physical disorders; disability in different areas of life such as at work, family, leisure time; individual coping strategies; treatment approaches in the past.

Is somatization a habituation disorder? Physiological reactivity in somatization syndrome.

The present study investigates whether physiological activity may play a part in maintaining the amplified perception of bodily processes typical for somatization. Eighty-one persons were classified into three groups by means of a structured clinical interview: 24 patients with somatization syndrome, 34 patients with somatization syndrome and comorbid major depression, and 23 healthy controls. Subjects completed four blocks of an attentional task, each of the blocks separated by resting periods. Physiological patterns demonstrated higher activity during mental tasks than during rest. The heart rate deceleration after changing from mental challenge to rest was less pronounced in the groups of patients with somatization syndrome than in controls. Moreover, patients with somatization syndrome reported feeling more and more tense during the investigation, while controls showed the tendency to habituate. The effects of heart rate and of feelings of tension partly replicated earlier findings, and demonstrated that physiological activity may interact with psychological processes in somatization.

Cortisol and somatization.

Somatization symptoms are frequently associated with depression, anxiety, and feelings of distress. These features interact with the activity of the HPA-axis. Therefore we investigated relationships between somatization symptoms and cortisol. Seventy-seven participants were classified into three groups: somatization syndrome (at least eight physical symptoms from the DSM-IV somatization disorder list), somatization syndrome combined with major depression, and healthy controls. The following data were collected: salivary cortisol at three time points (morning, afternoon, evening), nighttime urinary cortisol, serum cortisol after the dexamethasone suppression test (DST), and psychological variables such as depression, anxiety, somatization, and hypochondriasis. Salivary cortisol showed typical diurnal variations. However, the groups did not differ on any of the cortisol variables. A possible explanation may be counteracting effects of somatization and depression. Exploratory correlational analyses revealed that associations between cortisol and psychopathological variables were time-dependent. DST results correlated with psychological aspects of somatization, but not with the number of somatoform symptoms per se.

[Functional physical complaints. Guideline for diagnosis and treatment of somatoform disorders].

Although physical symptoms are the main reason why people go to the doctor, in many cases no unequivocal underlying organic disturbances are to be found, not even during subsequent visits to the doctor (Kroenke & Mangelsdorff, 1989). Frequently, the patient's previous history contains pointers for other physical complaints that also had no unequivocal organic etiology. This group of patients, who often present their problem in a very complaining fashion, are considered by many physicians to be difficult, bothersome, and ungrateful. Until quite recently it was assumed that the chances of successful treatment in these patients were poor. Accordingly, an American standard textbook of psychiatry recommends, as the main aim of the treatment, avoiding iatrogenic harm (Barsky, 1988). The present article wishes to make it clear that such a pessimistic assessment of the therapeutic outcome is no longer warranted. A positive effect can now be achieved with ambulatory psychotherapeutic measures both in the offices of general practitioners or internists, and in hospitals offering integrative-psychosomatic treatment on an inpatient basis.

Toward empirically based criteria for the classification of somatoform disorders.

There is a major need for an empirical evaluation of classification criteria for somatoform disorders. The present study analyzes psychometric properties of the existing criteria for somatization disorder. The full sample consisted of 324 patients seeking help because of "psychosomatic problems." Data from a subsample of carefully diagnosed patients with somatization syndrome (n = 76) and a clinical comparison group (n = 32) permitted the analysis of the discriminative power of items. Twenty-one somatic symptoms adopted from DSM-IV and ICD-10 criteria did not exhibit the necessary psychometric characteristics (item probability, item-total correlation, etc.). Thirty-two somatic symptoms showed a satisfactory psychometric performance. A cut-off of seven or more symptoms yielded the best discrimination between low and high disability. New criteria for somatization syndrome ("polysymptomatic somatoform disorder") are proposed taking into account for the strong association of somatization and abnormal illness behavior.

Meeting the expectations of chronic tinnitus patients: comparison of a structured group therapy program for tinnitus management with a problem-solving group.

Two different group treatments were evaluated in 144 in-patients suffering from impairment due to chronic tinnitus. A tinnitus management therapy (TMT) was developed using principles of cognitive-behavioral therapy and compared with problem solving group therapy. Self-ratings were used to evaluate the help patients found in dealing with life problems and tinnitus as well as the degree to which they felt they were being properly treated and taken seriously. Patients showed significantly more satisfaction with the TMT group and evaluated the help they found in coping with tinnitus and life problems significantly higher. Thus, in the light of unsatisfactory medical solutions and the poor acceptance of some psychological treatments for tinnitus, TMT appears to be an acceptable and helpful treatment program.

Cognitive aspects of hypochondriasis and the somatization syndrome.

The aim of this study was to evaluate whether specific cognitive aspects are present in patients suffering from somatoform disorders. With a sample of 493 patients from a center for behavioral medicine, the authors evaluated a questionnaire assessing typical cognitions concerning body perception, illness behavior, and health. The authors further examined 225 participants, including patients with a somatization syndrome, patients with somatization syndrome and additional hypochondriasis, patients with hypochondriasis, patients with other mental disorders (clinical control group), and nonclinical controls. The results showed that not only patients with hypochondriasis but also patients with somatization syndrome had cognitive concerns and assumptions that were specific for the disorder. These patients had a self-concept of being weak and unable to tolerate stress. A catastrophizing interpretation of minor bodily complaints found in hypochondriacal patients in earlier studies was also found for patients with multiple somatization symptoms.

How disabled are patients with somatoform disorders?

The purpose of this study was to evaluate the level and quality of psychosocial disabilities in patients suffering from somatoform disorders (SFD). Of 221 patients referred for psychiatric and cognitive-behavioral inpatient treatment, 37 were diagnosed according to DSM-IV as having SFD, 56 as pain disorder, 70 met the criteria for the subsyndromal form of SFD called the "Somatic Symptom Index" (SSI). The control group consisted of 58 patients with other mental disorders. All patients completed the Dysfunctional Analysis Questionnaire (DAQ) which measures social, vocational, personal, familial, and cognitive disabilities on psychometric scales. The results showed substantial disabilities in all somatoform subgroups; however, the levels and patterns of dysfunction in these patients were not statistically different from those in the control group. Impairment was generally more severe when patients had a comorbidity of somatoform and affective disorders. It is concluded that SFDs are associated with marked psychosocial disabilities similar to those seen in other mental disorders. The strongest predictor for psychosocial dysfunction is the comorbidity of somatoform with affective disorders, but not with anxiety disorders.

Effects of fluvoxamine on depression, anxiety, and other areas of general psychopathology in bulimia nervosa.

The efficacy of fluvoxamine in maintaining improvement of general psychopathology (depression, obsessive-compulsive symptoms, anxieties, interpersonal trust, and body perception) was tested in a double-blind placebo-controlled study of 72 patients with bulimia nervosa who were being treated successfully with inpatient behavioral psychotherapy. Over a period of about 15 weeks (2-3 weeks inpatient titration phase, 12 weeks outpatient relapse-prevention phase), fluvoxamine or placebo were given. The relapse-prevention design was used to avoid potential confounding effects of other concomitant treatments. Assessments concerning general psychopathology were made on the basis of expert ratings (CGI, HDRS) and self ratings (HSCL, Eating Disorders Inventory (EDI)-subscales "ineffectiveness," "perfectionism," "maturity fears," "interpersonal distrust," and "interoceptive awareness"). Fluvoxamine had significant effects in preventing relapse as measured on the basis of the Clinical Global Impression (CGI) scale "severity of illness", and a positive trend for relapse preventing effects was observed for the HSCL "general symptomatic index". Further, a relapse preventing effect was observed for the HSCL subscale "obsessive-compulsive symptoms", but not for the EDI subscale "perfectionism". Various dependent variables measuring depression showed no significant relapse-preventing effects of fluvoxamine, but only positive trends. Fluvoxamine had no relapse preventing effects according to our results for dependent variables assessing anxieties, interpersonal trust, and body perception. During a final short (4-week) off-medication phase, no statistically significant effects of discontinuation of medication, but some trends in the expected directions, were observed.

What does the Toronto Alexithymia Scale TAS-R measure?

One hundred seventy four inpatients of a psychosomatic hospital were examined with the revised version of the Toronto Alexithymia Scale TAS-R, as well as further measures of emotionality, somatization, psychopathology and personality. A significant association was found between TAS alexithymia and the number of somatoform symptoms. This association, however, disappeared when it was corrected for the possible impact of depression. The factor 1 of the TAS (ability to describe feelings to others) correlated significantly with the use of negative emotional words. Thus TAS alexithymics do not use less, but more emotional words, especially words describing negative feelings. The validity of factor 2 (externally oriented thinking) seems to be low. TAS alexithymia may measure specific aspects of depression or general distress.

Fluvoxamine in prevention of relapse in bulimia nervosa: effects on eating-specific psychopathology.

In a double-blind, placebo-controlled study of 72 patients with bulimia nervosa treated successfully with inpatient psychotherapy, the efficacy of fluvoxamine in maintaining improvement was tested. Fluvoxamine and placebo, respectively, were given over a period of about 15 weeks (2-3 weeks inpatient titration phase, 12 weeks outpatient relapse-prevention [maintenance] phase). The variables assessed concerned bulimic behavior and other aspects of eating disorders, global status, depression, anxieties, obsessive-compulsive behavior, and other aspects of psychopathology. Because the dropout rate was relatively high (N = 27 [33%]) and because it was considerably higher in the fluvoxamine group (19 out of 37 subjects), analyses were performed on the intent-to-treat sample (ideally including all 72 subjects). Results of the completer sample analyses (including only those subjects who finished the study) are briefly presented for comparison. In both the intent-to-treat and the completer analyses, the following scales showed fluvoxamine to have a significant effect in reducing the return of bulimic behavior: (1) self-ratings: Eating Disorder Inventory (EDI)-bulimia, urges to binge in previous week and the number of actual binges in the previous week; (2) expert ratings: Psychiatric Status Rating Scales for Bulimia nervosa, Structured Interview for Anorexia and Bulimia nervosa (SIAB)-"total score," SIAB-subscale "fasting," and SIAB-subscale "vomiting." Two further variables (EDI-total score and SIAB-subscale "bulimia") showed the superior relapse prevention effects of fluvoxamine compared with placebo for the completer sample, while they did not reach significance for group-by-time interactions in the intent-to-treat sample. During a final, short (4-week) off-medication phase, no effect of the discontinuation of medication was observed.

The classification of multiple somatoform symptoms.

This study evaluated the concordance among different approaches to diagnose patients with multiple somatoform symptoms. Inpatients (N = 108) of a center for behavioral medicine were diagnosed using a structured clinical interview. Somatization disorder according to DSM-IV and ICD-10 was as rare as somatization disorder according to DSM-III-R. The overlap between the criteria of DSM and ICD for somatization disorder was lower than that between DSM-III-R and DSM-IV. Somatoform autonomic dysfunction, a diagnostic category proposed by ICD-10, included fewer patients diagnosed with somatization disorder than the criteria of Escobar and colleagues for abridged somatization disorder (SSI-4/6: this Journal 177:140-146, 1989). Therefore, the Escobar criteria may be a common link between ICD-10 and DSM-IV. Although the original Escobar criteria were built upon the symptom list of DSM-III-R somatization disorder, SSI-3/5 is an empirically derived equivalent according to DSM-IV in our study (a minimum of 3 symptoms for men or 5 symptoms for women out of the list of 33 somatization symptoms according to DSM-IV).

Responses to activation and rest in patients with panic disorder and major depression.

Physical activity may be a trigger for panic attacks in patients with panic disorder, while exercise may have an antidepressant effect in patients with major depression. In order to examine reactions to rest as well as to exercise periods, we assessed physiological responses (heart rate, blood pressure), subjective responses on a visual analogue scale, and attentional responses with the span of apprehension test. Twenty participants met the diagnostic criteria for panic disorder, 20 patients had major depression, and 20 participants served as controls. Patients with major depression showed slower reaction times than participants in the other groups; this difference was more pronounced with increased task difficulty. Physical activation led to lower depression scores in all groups. Patients with panic disorder had elevated anxiety scores after physical activation, but also after rest. Heart rate as well as systolic blood pressure showed the expected acceleration after physical activation, but there were no differences between the groups. Activation did not seem to influence attentional performance as measured by the span of apprehension test. Results are consistent with a cognitive view of panic disorder. In contrast to patients with panic disorder, patients with major depression seem to have an attentional deficit which is more pronounced with more complex cognitive processing.
