Psychological assessment in cardiac rehabilitation

Psychological Factors Affecting Medical Condition: A New Proposal for DSM-V

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

Recognizing increased risk of depressive comorbidity after myocardial infarction: looking for 4 symptoms of anxiety-depression

BACKGROUND

Screening for depression in myocardial infarction (MI) patients must be improved: (1) depression often goes unrecognized and (2) anxiety has been largely overlooked as an essential feature of depression in these patients. We therefore examined the co-occurrence of anxiety and depression after MI, and the validity of a brief mixed anxiety-depression index as a simple way to identify post-MI patients at increased risk of comorbid depression.

METHODS

One month after MI, 176 patients underwent a psychiatric interview and completed the Beck Depression Inventory (BDI) and the Symptoms of Anxiety-Depression index (SAD(4)) containing four symptoms of anxiety (tension, restlessness) and depression (feeling blue, hopelessness).

RESULTS

Thirty-one MI patients (18%) had comorbid depression and 37 (21%) depressive or anxiety disorder. High factor loadings and item-total correlations (SAD(4), alpha = 0.86) confirmed that symptoms of anxiety and depression co-occurred after MI. Mixed anxiety-depression (SAD(4)>or=3) was present in 90% of depressed MI patients and in 100% of severely depressed patients. After adjustment for standard depression symptoms (BDI; OR = 4.4, 95% CI 1.6-12.1, p = 0.004), left ventricular ejection fraction, age and sex, mixed anxiety-depression symptomatology was associated with an increased risk of depressive comorbidity (OR = 11.2, 95% CI 3.0-42.5, p < 0.0001). Mixed anxiety-depression was also independently associated with depressive or anxiety disorder (OR = 9.2, 95% CI 3.0-27.6, p < 0.0001).

CONCLUSIONS

Anxiety is underrecognized in post-MI patients; however, the present findings suggest that anxiety symptomatology should not be overlooked in these patients. Depressive comorbidity after MI is characterized by symptoms of mixed anxiety-depression, after controlling for standard depression symptoms. The SAD(4) represents an easy way to recognize the increased risk of post-MI depression.

Psychological aspects of primary aldosteronism

BACKGROUND

Except for 3 case reports of Conn's syndrome presenting as depression, psychosocial factors have not been explored in primary aldosteronism. We investigated psychological correlates in primary aldosteronism using methods that were found to be sensitive and reliable in psychosomatic research.

METHOD

Ten consecutive newly diagnosed patients with primary aldosteronism were studied: 5 males/5 females; mean age (+/-SD) 45.5 +/- 6.6 years, age range 34-54 years; 4 with an aldosterone-producing adenoma and 6 with idiopathic aldosteronism; systolic/diastolic blood pressure 189 +/- 20/111 +/- 7.7 mm Hg; upright plasma aldosterone 40.0 +/- 18.3 ng/dl; upright plasma renin activity (PRA) 0.2 +/- 0.1 ng/ml/h; aldosterone/PRA ratio 229.2 +/- 191.0; serum K(+) 3.5 +/- 0.5 mmol/l. The Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) for eliciting psychiatric diagnoses, and a shortened version of the structured interview for subclinical psychological syndromes, the Diagnostic Criteria for Psychosomatic Research (DCPR), were administered.

RESULTS

Seven patients (2 with aldosterone-producing adenoma and 5 with idiopathic hyperaldosteronism) received both DSM-IV and DCPR diagnoses, while 3 had neither. As to DSM-IV, generalized anxiety disorder was detected in 6 cases (in 1 it was associated with panic disorder and in 1 with major depression) and obsessive-compulsive disorder in 1. The most frequent DCPR cluster was demoralization (5 cases), while persistent somatization occurred in 2 cases (associated with demoralization in 1) and irritable mood in 1.

CONCLUSIONS

The occurrence of anxiety disorders in patients with primary aldosteronism was much higher than that found in the general population and in primary care. Since an association between hyperaldosteronism and anxiety has also been suggested in previous animal studies, it seems worthwhile to gain further knowledge on clinical aspects by larger population studies.

Minor depression as a cardiac risk factor after coronary artery bypass surgery

A few studies have investigated the role of psychosocial variables on clinical outcomes in coronary artery bypass grafting patients. The aims of this prospective study were 1) to assess clinical and subclinical distress in a consecutive sample of patients who underwent coronary artery bypass grafting surgery at both a 1-month assessment and a 6- to 8-year follow-up visit; and 2) to investigate the relationship between psychological variables and coronary events. A consecutive series of 47 patients with recent coronary artery bypass grafting surgery was evaluated by means of observer-rated categories (both the Diagnostic and Statistical Manual [DSM] and the new Diagnostic Criteria for Psychosomatic Research [DCPR]), and self-rated scales such as the Psychosocial Index. Survival analysis was used to characterize the clinical course of patients at the 6- to 8-year follow-up. One month after surgery, at the first psychological assessment, 36% of patients received a psychiatric diagnosis, and almost half of the sample met the criteria for a DCPR cluster. At follow-up, only abnormal illness behavior scores varied significantly from those at the first evaluation. Among the variables examined as potential risk factors for coronary events, only minor depression attained statistical significance. Psychological evaluation of patients who underwent coronary artery bypass grafting surgery needs to incorporate both clinical (DSM) and subclinical (DCPR) methods of classification. Furthermore, the data suggest minor depression as a potential cardiac risk factor in coronary artery bypass grafting patients. The clinical approach to coronary artery bypass grafting patients should thus include not only major depressive symptoms but also minor depression.

Validation of a simplified definition of anger attacks

BACKGROUND

Anger attacks, sudden spells of anger with vegetative hyperarousal, are highly prevalent symptoms in depression. Assessment normally requires the use of specific instruments. The aim of this study was the validation of a simplified definition for anger attacks.

METHODS

Anger attacks were assessed in 203 patients suffering from major depression with the Anger Attacks Questionnaire. The first three items of the questionnaire (irritability, overreaction to minor annoyances, episodes with inappropriate anger or rage) were compared separately with the diagnosis, and their value as single screening questions to establish the diagnosis was assessed.

RESULTS

Irritability was only weakly associated with the diagnosis of anger attacks (Cohen's kappa kappa = 0.214 +/- 0.058) and yielded a rather low specificity (0.302), while overreaction to minor annoyances (kappa = 0.869 +/- 0.037) and the question about episodes with inappropriate anger or rage (kappa = 0.901 +/- 0.032) had a high degree of agreement with the diagnosis of the questionnaire (specificity 0.918 and 0.935, respectively). The combination of the two later items resulted in an almost perfect reclassification of cases (kappa = 0.955 +/- 0.022; specificity = 0.971).

CONCLUSIONS

As anger attacks are probably underdiagnosed in clinical practice, simplification of the diagnostic process is imperative. Our results demonstrate that asking one or two simple screening questions suffices to recognize the majority of patients with anger attacks.

Integration of Multiple Criteria for Psychosomatic Assessment of Dermatological Patients

Psychological distress has been frequently reported in the setting of skin disorders. The Diagnostic Criteria for Psychosomatic Research (DCPR) have been found to yield valuable integrative information, in addition to DSM-IV nosology, in a variety of medical diseases. The aim of this study was to verify whether this integration could also be helpful in dermatology. A consecutive series of 539 inpatients with various skin conditions was evaluated by means of structured interviews for DSM-IV and DCPR diagnoses. The prevalence of DSM-IV conditions was 38% (mostly depressive disorders and anxiety disorders), whereas that of DCPR clusters (mostly demoralization and somatization secondary to psychopathology) was 48%. Overall, DCPR diagnoses were significantly more frequent than DSM-IV categories, regardless of the presence or absence of a psychiatric disorder. Psychological assessment of patients with skin diseases needs to incorporate both clinical (DSM-IV) and subclinical (DCPR) methods of classification. The health status of these patients can be improved if their psychological problems are appropriately assessed and recognized.

Use of the Diagnostic Criteria for Psychosomatic Research (DCPR) in a Community Sample

The authors assessed the prevalence of Diagnostic Criteria for Psychosomatic Research (DCPR) clusters in a community sample and the association between these syndromes and psychosocial variables. A group of 347 consecutive subjects from the general population were administered the semistructured interview for DCPR and a self-rating scale (the Psychosocial Index). A DCPR syndrome was identified in 59% of subjects. These subjects showed more stress and distress and less well-being than those without a DCPR syndrome. Some DCPR syndromes (alexithymia, Type A behavior, irritable mood) are frequently encountered in a community sample and are associated with impairment in quality of life. Other syndromes (demoralization, persistent somatization) that have been frequently found in medically ill persons were uncommon in this general-population sample.

Irritable mood in Italian patients with medical disease

Irritability may be a mood state independent of other moods and anxiety disorders, even though it may be symptomatic of several psychiatric disorders, such as major depression. The aims of this exploratory study were to verify the presence of irritable mood in a group of medical outpatients with a variety of clinical conditions (functional gastrointestinal disorders, cardiovascular disorders, endocrine diseases and cancer) and to examine its relationship with major depression. A total of 609 consecutive outpatients recruited from different medical settings were assessed according to DSM-IV and Diagnostic Criteria for Psychosomatic Research using semistructured research interviews. Irritable mood was identified in 163 (27%) patients, while major depression was present in 113 (19%) patients. Even though there was a considerable overlap between the two diagnoses, 76 (67%) patients with major depression were not classified as irritable, and 126 (77%) patients with irritable mood did not satisfy the criteria for major depression. The findings suggest a high prevalence of irritability in the medically ill, which in most cases is independent of mood disorder. Further research may determine whether irritability, alone or in association with major depression, entails prognostic and clinical implications.

The development of the Toronto Structured Interview for Alexithymia: item selection, factor structure, reliability and concurrent validity

BACKGROUND

Assessments of personality constructs increasingly use self-report and structured interview instruments, which allow for a multimethod measurement approach and decrease specific measurement method bias. The aim of this study was to develop a valid and reliable structured interview for assessing the alexithymia construct.

METHODS

Sixty interview questions were written initially, each with a set of scoring criteria and prompts and probes to elicit information assisting in the scoring of the respondents' answers.

RESULTS

After pilot testing, the number of questions was reduced to 43, which were administered to 136 community participants and 97 psychiatric outpatients. A series of item and scale analyses further reduced the item pool to 24 items. Principal component analysis and confirmatory factor analysis of these 24 items revealed preliminary evidence of a hierarchical, four-factor structure, with four lower factors nested within two higher-order latent factors. This structural configuration resulted in the Toronto Structured Interview for Alexithymia (TSIA) with two domain scales and four facet scales. The TSIA and its six scales demonstrated acceptable levels of interrater, internal, and retest reliability. The TSIA and its scales correlated modestly but significantly with the 20-item Toronto Alexithymia Scale and its three factor scales, providing some support for the concurrent validity of this interview.

CONCLUSION

The TSIA appears to be a promising structured interview for assessing alexithymia.

Influence of anxiety on the course of heart disease after acute myocardial infarction - risk factor or protective function?

BACKGROUND

There is a lack of clarity concerning the effect of anxiety on the course of cardiac events following myocardial infarction. Some studies have identified anxiety as a risk factor for further cardiac events. However, it is also considered to be a protective factor, as a higher level of anxiety may improve patient compliance and regular medical checkups.

METHODS

A group of 76 patients with myocardial infarction underwent physical examination and had their anxiety levels assessed within the first week, and 31 months after myocardial infarction. Cardiac events were documented during the follow-up period. We investigated the predictive value for the occurrence of cardiac events of sociodemographic, psychological and physical parameters when evaluated within the first week after myocardial infarction. Compliancy and regularity of medical checkups were registered.

RESULTS

Cardiac events occurred in 24 patients during a mean follow-up period of 31 months. The group of anxious patients not only suffered more often from cardiac events, these events also occurred earlier than in nonanxious patients. Age, gender, partner status, level of anxiety and comorbid diabetes at the time of first assessment proved to be discriminatory variables between patients suffering further cardiac incidents and those free of further events. Anxious patients were more likely to continue smoking, whereas less anxious patients were more likely to give up smoking.

Psychological and quality-of-life outcomes from a comprehensive stress reduction and lifestyle program in patients with coronary artery disease: results of a randomized trial

BACKGROUND

Stress reduction and comprehensive lifestyle modification programs have improved atherosclerosis and cardiac risk factors in earlier trials. Little is known about the impact of such programs on quality-of-life (QoL) and psychological outcomes. Given recent significant improvements in cardiac care, we evaluated the current benefit of stress reduction/lifestyle modification on QoL and emotional distress in patients with coronary artery disease (CAD).

METHODS

101 patients (59.4 +/- 8.6 years, 23 female) with CAD were randomized to a 1-year lifestyle/stress management program (n = 48) or written advice (n = 53). QoL and psychological outcomes were assessed with the SF-36, Beck Depression, Spielberger State/Trait Anxiety, Spielberger State/Trait Anger and Perceived Stress Inventories. Group repeated-measures analyses of variance were performed for all measures.

RESULTS

Adherence to the program was excellent (daily relaxation practice 39 +/- 5 vs. 5 +/- 8 min, respectively; p < 0.001). Both groups improved comparably in most dimensions of QoL, and significantly greater improvements for the lifestyle group were found for physical function and physical sum score (p = 0.046 and p = 0.045). Depression, anxiety, anger and perceived stress were reduced similarly in both groups. However, intervention x gender interaction effects revealed greater benefits among women in the lifestyle intervention vs. advice group for depression and anger (p = 0.025 and p = 0.040), but no effects for men.

CONCLUSIONS

A comprehensive lifestyle modification and stress management program did not improve psychological outcomes in medically stable CAD patients. The program did appear to confer psychological benefits for women but not men. Further trials should investigate gender-related differences in coronary patient responses to behavioral interventions.

Psychosomatic assessment of skin diseases in clinical practice

BACKGROUND

Psychiatric disorders are frequent in dermatology patients, and many studies pointed out complex, mutual relationships between psyche and skin. Our aim was to provide a systematic psychosocial evaluation of a large and heterogeneous population of patients with skin diseases, including assessments of quality of life, psychiatric status according to the DSM-IV and psychological conditions with psychosomatic relevance according to established criteria (Diagnostic Criteria for Psychosomatic Research, DCPR).

METHODS

We studied 545 dermatological inpatients aged 18-65 years, free from dementia and cognitive impairment. They completed the Skindex-29 and the 12-item General Health Questionnaire (GHQ-12) and were administered the SCID-I and the Structured Interview for Psychological Conditions of Psychosomatic Relevance by a trained mental health professional blinded to questionnaire scores.

RESULTS

Overall, 38% of patients received a DSM-IV diagnosis. The most common diagnoses were mood (20%) and anxiety disorders (16%); 48% of patients also received a DCPR diagnosis. The most common were demoralisation, irritable mood, type A behaviour and various forms of abnormal illness behaviour. Adjusting for gender, age, and education, the presence of DSM-IV or DCPR diagnoses was significantly associated with high scores on the GHQ-12 and on the Functioning and Emotions scales of the Skindex-29. Also, DCPR diagnoses were significantly associated with high scores on the Symptoms scale of the Skindex-29.

CONCLUSIONS

These findings highlight the high frequency of psychosocial problems in patients with skin disease and suggest that the joint use of DSM-IV and DCPR criteria may help identify those patients in whom psychiatric issues are worthy of increased clinical attention.

Prodromal symptoms in myocardial infarction

BACKGROUND

Little is known about the prodromal phase of myocardial infarction (MI). The aim of this study was to explore this phase with methodologies which have been standardized in affective disorders. The psychological evaluation of patients with MI diagnosis is currently based on DSM-IV criteria. An alternative diagnostic and conceptual framework has been proposed by an international group of psychosomatic investigators. In this study, we are going to compare these new criteria, i.e. the Diagnostic Criteria for Psychosomatic Research (DCPR), with DSM-IV in a population where a high prevalence of psychological problems is expected.

METHODS

A semistructured research interview based on Paykel's Clinical Interview for Depression for eliciting prodromal symptoms was administered to a consecutive series of 92 patients with a first episode MI diagnosis. Two interviews for the evaluation of psychological problems were administered according to DSM-IV and DCPR criteria.

RESULTS

Most of the patients reported prodromal symptoms. Irritability, depressed mood and somatic anxiety were the most common prodromal symptoms. The results also show that the number of DCPR diagnoses was higher than the number of DSM-IV diagnoses. At least one DCPR diagnosis was found in all patients, whereas at least one DSM-IV diagnosis was present in 42 (46%) patients.

CONCLUSIONS

The prodromal phase of MI was found to be characterized by prodromal symptoms of affective type. The joint use of DSM-IV and DCPR criteria was found to improve the identification of psychological factors which could affect this phase. The results should alert the physician to the fact that patients presenting with irritability, depressed mood (including demoralization), anxiety and insomnia may be at risk of developing coronary artery disease.

Alexithymia and interpersonal problems

BACKGROUND

Interpersonal relationships are substantially codetermined by nonverbal communication, e.g. facial affect. Given the deficits of nonverbal affect recognition and expression in alexithymia, we hypothesized that alexithymics had more interpersonal problems than nonalexithymic individuals, and that the various facets of the alexithymia construct are differentially related to interpersonal problems.

METHOD

149 subjects participating in an inpatient group psychotherapy program completed the Toronto Alexithymia Scale (TAS-20) and the Inventory of Interpersonal Problems (IIP-C) at the beginning of the treatment. The IIP-C was also administered to a subgroup at the end of the treatment.

RESULTS

Based on the alexithymia scores, patients were classified as low- (TAS-20 score </=51), moderate- or high-alexithymic (TAS-20 score >/=61). High-alexithymic patients had significantly more interpersonal problems than low alexithymics, particularly in the IIP-C scales indicating hostility and social avoidance. The TAS-20 subscale difficulty describing feelings showed the highest correlations with interpersonal problems (r between 0.23 and 0.55). At the end of the treatment, the high alexithymics still scored highest on the IIP-C, but the magnitude of change in interpersonal problems did not differ across the groups.

CONCLUSIONS

Our findings suggest that the interpersonal style of alexithymic individuals is characterized by a cold and socially avoidant behavior, corresponding to the predominantly insecure attachment pattern found in alexithymia. Additionally, our results indicate that group psychotherapy is as helpful for alexithymic as for nonalexithymic subjects with respect to interpersonal problems. Finally, we propose that alexithymia involves a reduced capacity to use social interactions for affect regulation.

Stressful life events, depression and demoralization as risk factors for acute coronary heart disease

BACKGROUND

While the effect of psychological stress and depression on the course of heart disease is commonly recognized, the relationship between recent life events, major depression, depressive symptomatology and the onset of acute coronary heart disease (CHD) has been less considered. The aim of this study was to investigate the presence of stressful life events, major and minor depression, recurrent depression and demoralization in the year preceding the occurrence of a first acute myocardial infarction (AMI) and/or a first episode of instable angina and to compare stressful life events, also related with mood disorders, in patients and healthy controls.

METHODS

97 consecutive patients with a first episode of CHD (91 with AMI and 6 with instable angina) and 97 healthy subjects matched for sociodemographic variables were included. All patients were interviewed with Paykel's Interview for Recent Life Events, a semistructured interview for determining the psychiatric diagnosis of mood disorders (DSM-IV), a semistructured interview for demoralization (DCPR). Patients were assessed while on remission from the acute phase. The time period considered was the year preceding the first episode of CHD and the year before the interview for controls.

RESULTS

Patients with acute CHD reported significantly more life events than control subjects (p < 0.001). All categories of events (except entrance events) were significantly more frequent. 30% of patients were identified as suffering from a major depressive disorder; 9% of patients were suffering from minor depression, 20% from demoralization. Even though there was an overlap between major depression and demoralization (12%), 17% of patients with major depression were not classified as demoralized and 7% of patients with demoralization did not satisfy the criteria for major depression. Independently of mood disorders, patients had a higher (p < 0.001) mean number of life events than controls. With regard to life events, the same significant difference (p < 0.001) compared to controls applied to patients with and without mood disorders.

CONCLUSIONS

Our findings emphasize, by means of reliable methodology, the relationship between life events and AMI. These data, together with those regarding traditional cardiac risk factors, may have clinical and prognostic implications to be verified in longitudinal studies.

Use of the diagnostic criteria for psychosomatic research in oncology

BACKGROUND

Psycho-oncology literature has shown that 30-50% of cancer patients meet the criteria for a psychiatric diagnosis, according to the usual nosographic classification (e.g. DSM). The Diagnostic Criteria for Psychosomatic Research (DCPR) have been shown to be useful in identifying psychological constellations in patients with medical illness. The aims of the study were to compare the DSM-IV and the DCPR in their application to cancer patients.

METHOD

One hundred and forty-six patients with cancer underwent semistructured interviews to assess psychiatric morbidity and psychosocial syndromes according to the DSM-IV and the DCPR, respectively. The Brief Symptom Inventory (BSI) was also used to assess psychological stress symptoms.

RESULTS

Sixty-five subjects (44.5%) met the criteria for a DSM-IV diagnosis (DSM cases), while 104 patients (71.2%) presented symptoms meeting the criteria for at least one DCPR syndrome. Three DCPR dimensions were more frequent than others, specifically Health Anxiety (37.7%), Demoralization (28.8%) and Alexithymia (26%). Among the subjects with no formal DSM-IV diagnosis (n = 81), 58% had at least one DCPR syndrome. DSM-IV cases had higher scores on several BSI subscales in comparison with patients with only one DCPR syndrome, while no difference was found in patients with more than one DCPR diagnosis.

CONCLUSIONS

The DCPR system was found to be useful in oncology in investigating psychological conditions which are not identified by the DSM-IV alone. Assessment of more specific constructs, other than intensity of general stress symptoms, may give more specific information and help in tailoring psychological intervention for patients with cancer.

Prevalence of Depressive Disorders in Men and Women Enrolled in Cardiac Rehabilitation

PURPOSE

Epidemiological studies have demonstrated that depression is an independent risk factor for the development and recurrence of coronary heart disease (CHD). The prevalence of depressive disorders, however, is not well documented in CHD patients enrolled in cardiac rehabilitation (CR). The purpose of this study was to estimate the prevalence of current and lifetime depressive disorders in the CR setting.

METHODS

One hundred ten men and women diagnosed with CHD and enrolled in a phase II CR program were screened via a psychiatric, structured interview to assess current and lifetime history of major depressive disorder, minor depression, and dysthymic disorder.

RESULTS

A total of 17 (15.5%) individuals screened positive for a current depressive disorder at entry into the CR program, with 10 (9.1%) individuals screening positive for major depressive disorder, 7 (6.4%) for minor depression, and 6 (5.5%) for dysthymic disorder. With respect to lifetime prevalence of mood disorders, 29 (26.4%) individuals met the diagnostic criteria for at least one depressive disorder during their lifetime. The lifetime prevalence of major depressive disorder, minor depression, and dysthymic disorder was 11.8%, 14.5%, and 10.9%, respectively. Female CR participants evidence significantly higher current and lifetime prevalence rates for depressive disorders compared to their male counterparts.

CONCLUSIONS

The results of this study suggest that a substantial number of CHD patients enrolled in CR report a clinically significant history of depression. Efforts to assess and treat depression are needed in the CR setting and may be associated with better adherence to lifestyle modification programs.

Psychiatric and psychosocial outcome of cardiac surgery with cardiopulmonary bypass: a prospective 12-month follow-up study

Little is known concerning the natural history of psychiatric morbidity, postoperative delirium, cognitive decline and health-related quality of life (HRQOL) in cardiac surgery patients and the impact of neurocognitive dysfunction on HRQOL after cardiac surgery with cardiopulmonary bypass (CPB). In a prospective study, we followed up for 1 year 30 of the original 34 patients who had undergone cardiac surgery with CPB. Patients were assessed preoperatively, before discharge, and at 1 year after surgery with the Structural Clinical Interview for DSM-IV and a series of neuropsychological tests. Psychometric scales were administered to evaluate cognitive functioning (Syndrom Kurztest), depressive symptomatology (Montgomery-Asberg Depression Rating Scale), posttraumatic stress symptoms (Posttraumatic Stress Syndrome 10-Questions Inventory) and HRQOL (SF-36 Health Status Questionnaire). Delirium Rating Scale (DRS) was used daily over the course of intensive care unit treatment. Postoperative delirium developed in 11 of the 34 patients (mean DRS rating scale score+/-S.D.: 20.36+/-6.22, range: 14-31). Short-term consequences of cardiac surgery included adjustment disorder with depressed features (n=11), posttraumatic stress disorder (n=6), major depression (n=6) and clinically relevant cognitive deficits (n=13). At 12 months, the severity of depression and anxiety disorders improved and returned to the preoperative level, and 6 out of the 30 followed-up patients displayed cognitive deficits. Our patients' HRQOL SF-36 self-reports significantly improved compared with baseline quality of life data. However, 1-year overall lower cognitive function scores were associated with lower HRQOL. Cardiac surgery with CPB is associated with improvements in HRQOL relative to the preoperative period, but the presence of cardiac surgery-related cognitive decline impairing HRQOL is a complication for a subgroup of cardiac surgical patients in the long-term outcome.

Diagnostic Criteria for Psychosomatic Research and Psychosocial Variables in Breast Cancer Patients

The aim of the study was to examine the relationship of the Diagnostic Criteria for Psychosomatic Research (DCPR) with psychosocial variables and quality of life among cancer patients. Of 105 women with breast cancer who participated in the study, 40 (38.1%) had symptoms meeting the criteria for at least one DCPR syndrome, and 30 (28.6%) had more than one DCPR syndrome. Health anxiety, demoralization, and alexithymia were the most frequent DCPR syndromes. Patients who were diagnosed with DCPR syndromes reported higher levels of cancer-related worries and poorer quality of life than those without a DCPR diagnosis. Analysis of the single DCPR clusters and coping with cancer indicated that health anxiety was related to higher scores on the Mini-Mental Adjustment to Cancer (Mini-MAC) anxious preoccupation subscale, DCPR demoralization was related to higher scores on the Mini-MAC hopelessness subscale, and DCPR alexithymia was related to higher scores on the Mini-MAC avoidance subscale. The study indicates the usefulness of the application of the DCPR in breast cancer, although further research is needed to improve the feasibility and internal validity of DCPR constructs.

Prediction of treatment outcome of patients with functional gastrointestinal disorders by the diagnostic criteria for psychosomatic research

BACKGROUND

The Diagnostic Criteria for Psychosomatic Research (DCPR) have been demonstrated to be useful in identifying specific psychological conditions of medical patients. The aim of this study was to evaluate the clinical utility of the DCPR in predicting the treatment outcome of patients with functional gastrointestinal disorders (FGID).

METHODS

FGID outpatients were allocated to improved (n = 65) and unimproved (n = 40) groups on the basis of preestablished criteria following 6 months of treatment. Patients were administered the structured interview for DCPR at baseline and the Gastrointestinal Symptom Rating Scale both at baseline and follow-up.

RESULTS

In the unimproved patients, the prevalence of the DCPR categories of alexithymia (82.2%) and persistent somatization (72.5%) was significantly higher while health anxiety was more prevalent in improved patients (21.5%). No unimproved patient lacked a DCPR diagnosis while multiple DCPR diagnoses were significantly higher in the unimproved group (90%). In the regression analysis, alexithymia, persistent somatization, a higher number of DCPR diagnoses for each patient and, to a lesser extent, greater symptom severity at baseline were significant predictors of unimprovement. Health anxiety, even after controlling for gastrointestinal symptoms, was a significant predictor of improvement.

CONCLUSIONS

The ability to predict treatment outcome indicates the clinical utility of the DCPR. Clinicians may improve treatment outcome for FGID patients by identifying particular psychosomatic syndromes (alexithymia, persistent somatization, and health anxiety) and patients with multiple DCPR clusters, and attempting to address specific therapeutic interventions.

Persistent psychological distress in patients treated for endocrine disease

BACKGROUND

The purpose of the study was to assess the frequency and characteristics of psychological distress, even after adequate treatment, in the heterogeneous population of an endocrine outpatient clinic.

METHODS

146 endocrine patients (31 males/115 females; age 39.4 +/- 12.5 years), who were cured or in remission, were studied in a university endocrine outpatient clinic. Semistructured clinical interviews to assess psychiatric (Structured Clinical Interview for DSM-IV) and psychological (Diagnostic Criteria for Psychosomatic Research, DCPR) diagnoses were employed and were supplemented by self-rated instruments (the Psychosocial Index and the Medical Outcome Study short form General Health Survey) which could provide the patients' perception of their own quality of life.

RESULTS

There were 118 patients (81%) who presented with at least 1 psychiatric (DSM-IV) or psychological (DCPR) diagnosis. The most frequent diagnostic findings were generalized anxiety disorder (29%), major depression (26%), irritable mood (46%), demoralization (34%) and persistent somatization (21%). By self-rated instruments, patients with at least 1 DSM-IV or DCPR diagnosis reported significantly more stressful life circumstances, psychological distress and an impaired quality of life compared to those who had none.

CONCLUSIONS

A high prevalence of psychological distress may be encountered in the long-term follow-up of endocrine patients. A biopsychosocial consideration of the person and his/her quality of life appears to be mandatory for improving therapeutic effectiveness in endocrine disorders.
