Clinical Interviewing: An Essential but Neglected Method of Medicine.

Clinical interviewing is the basic method to understand how a person feels and what are the presenting complaints, obtain medical history, evaluate personal attitudes and behavior related to health and disease, give the patient information about diagnosis, prognosis, and treatment, and establish a bond between patient and physician that is crucial for shared decision making and self-management. However, the value of this basic skill is threatened by time pressures and emphasis on technology. Current health care trends privilege expensive tests and procedures and tag the time devoted to interaction with the patient as lacking cost-effectiveness. Instead, the time spent to inquire about problems and life setting may actually help to avoid further testing, procedures, and referrals. Moreover, the dialogue between patient and physician is an essential instrument to increase patient's motivation to engage in healthy behavior. The aim of this paper was to provide an overview of clinical interviewing and its optimal use in relation to style, flow and hypothesis testing, clinical domains, modifications according to settings and goals, and teaching. This review points to the primacy of interviewing in the clinical process. The quality of interviewing determines the quality of data that are collected and, eventually, of assessment and treatment. Thus, interviewing deserves more attention in educational training and more space in clinical encounters than it is currently receiving.

Clinimetric Criteria for Patient-Reported Outcome Measures.

Patient-reported outcome measures (PROMs) are self-rated scales and indices developed to improve the detection of the patients' subjective experience. Given that a considerable number of PROMs are available, it is important to evaluate their validity and usefulness in a specific research or clinical setting. Published guidelines, based on psychometric criteria, do not fit in with the complexity of clinical challenges, because of their quest for homogeneity of components and inadequate attention to sensitivity. Psychometric theory has stifled the field and led to the routine use of scales widely accepted yet with a history of poor performance. Clinimetrics, the science of clinical measurements, may provide a more suitable conceptual and methodological framework. The aims of this paper are to outline the major limitations of the psychometric model and to provide criteria for clinimetric patient-reported outcome measures (CLIPROMs). The characteristics related to reliability, sensitivity, validity, and clinical utility of instruments are critically reviewed, with particular reference to the differences between clinimetric and psychometric approaches. Of note is the fact that PROMs, rating scales, and indices developed according to psychometric criteria may display relevant clinimetric properties. The present paper underpins the importance of the clini-metric methodology in choosing the appropriate PROMs. CLIPROM criteria may also guide the development of new indices and the validation of existing PROMs to be employed in clinical settings.

Psychosomatic medicine in the 21st century: understanding mechanisms and barriers to utilization.

The psychosomatic approach arose in antiquity as mankind looked for explanations for illness and death. With the rise of modern medicine, the links between emotions and medical conditions, such as cardiac disease and diabetes, were described by astute clinical observers, but the mechanisms for these conditions were based on correlation from observations rather than on experimental design. Psychoanalytic theory was often utilized to explain many common diseases. For example, peptic ulcer disease was blamed upon anger and stress, but scientific methodology discovered Helicobacter pylori to be the significant causal factor of this disease and resulted in the development of more effective treatments. Nevertheless emotional factors are still linked to disease states and morbidity; for example, depression is a risk factor for mortality following myocardial infarction. Advances in neuroscience demonstrate that the reduction of telomere length by anxiety and stress leads to more rapid aging and potential disease vulnerability. Thus, neuroscientific probes may allow for the elucidation of psychosomatic mechanisms. Sadly, clinical barriers, in terms of time pressure upon physicians and the current separation of mental health services from primary care settings, continue the dualistic treatment of many conditions where psychological factors are important. It is not clear whether a mandate for the integration of behavioral health into primary care will remedy this partition and finally maximize a psychosomatic approach to medical care.

Alexithymia and emotional intelligence in patients with panic disorder, generalized anxiety disorder and major depressive disorder.

Emotional Intelligence (EI) is a broad personality construct signifying the ability to perceive and to regulate affects within oneself. Alexithymia is another personality construct denoting difficulty in identifying and expressing emotions, with an externally oriented thinking style. Although previously considered to be independent, some studies have shown that these constructs overlap. The aim of this study was to evaluate and compare the levels of EI and alexithymia in patients with panic disorder, major depressive disorder (MDD), and generalized anxiety disorder (GAD). The subjects included 171 psychiatric patients and 56 non-clinical controls. Psychiatric diagnoses were based on DSM-IV criteria. The Emotional Intelligence Scale-34 (EIS-34) and the Toronto Alexithymia Scale (TAS-20) were used to assess EI and alexithymia. All three patient groups scored statistically significantly higher than the non-clinical controls on TAS-20 total score and the TAS-20 subfactors of difficulty identifying feelings and difficulty describing feelings. EIS-34 scores were lower in patient groups than in the non-clinical controls, but only the EIS-34 intrapersonal subscale was significant difference. Total TAS-20 and EIS-34 scores in the patient cohort were inversely and significantly correlated These results reaffirm an overlap between EI and alexithymia with the intrapersonal factor of EI to be more dependent on the difficulty identifying feelings dimension of alexithymia in subjects with MDD and GAD.

Principles of psychosomatic assessment.

There is increasing awareness of the limitations of disease as the primary focus of medical care. It is not that certain disorders lack an organic explanation, but that our assessment is inadequate in most clinical encounters. The primary goal of psychosomatic medicine is to correct this inadequacy by incorporation of its operational strategies into clinical practice. At present, the research evidence which has accumulated in psychosomatic medicine offers unprecedented opportunities for the identification and treatment of medical problems. Taking full advantage of clinimetric methods (such as with the use of Emmelkamp's two levels of functional analysis and the Diagnostic Criteria for Psychosomatic Research) may greatly improve the clinical process, including shared-decision making and self-management. Endorsement of the psychosomatic perspective may better clarify the pathophysiological links and mechanisms underlying symptom presentation. Pointing to individually targeted methods may improve final outcomes and quality of life.

The psychosomatic interview.

The psychosomatic interview is a patient-focused dialogue between physician and patient. It differs from the traditional disease-focused encounter in that the psychosomatic approach includes the biological, psychological, and sociocultural domains irrespective of the patients initial complaint, whether somatic or psychological. The process of dyadic interaction and the techniques of open questions are reviewed. Specific issues such as the alexithymic patient and breaking bad news are challenges in such communications. Organizing the data into the perspectives of diseases, dimensions, behaviors, and life stories allows the clinician to best understand their patients within a psychosomatic milieu.

Kellner's emotional inhibition scale: a clinimetric approach to alexithymia research.

BACKGROUND: Emotional inhibition has been an enduring concept in the psychosomatic literature explaining the onset and course of medical disorders. Currently the personality style of alexithymia is a focus of this dimension in psychosomatic theory, while actual conscious emotional inhibition, which may overlap with alexithymia, has received less attention. In the early 80s Robert Kellner developed the Emotional Inhibition Scale (EIS), a self-rating scale for emotional inhibition based on clinimetric principles. In this study we explored whether the EIS differentiated a sample of cardiac recipients from normal controls, as well as the associations between the EIS and 2 measures of alexithymia, i.e. the Toronto Alexithymia Scale-20 (TAS-20) and the Diagnostic Criteria for Psychosomatic Research (DCPR). We also examined whether the EIS and the TAS-20 were differently related to depressive symptoms measured by the Symptom Questionnaire (SQ). METHODS: Ninety-five heart-transplanted patients and a sample of normal controls, matched for sociodemographic variables, were administered the EIS (total score and 4 subscales concerning 'verbal inhibition', 'timidity', 'disguise of feelings', and 'self-control'), the TAS-20, the SQ, and the Structured Interview according to the DCPR for alexithymia. RESULTS: Cardiac recipients did not display significant differences compared to normal controls in observer (DCPR) and self-rated (TAS-20) measures of alexithymia. There were, however, significant differences in EIS with regard to 'disguise of feelings'. In both groups the EIS 'verbal inhibition' and 'timidity' subscales were positively associated with the TAS-20, while the EIS 'disguise of feelings' and 'self-control' subscales were independent of alexithymia. Depressive symptoms were more related to TAS-20 than EIS total scores. CONCLUSIONS: Our results suggest that emotional inhibition and alexithymia are distinct phenomena even though they may share certain features. The EIS appears to be relatively independent of depressed mood and will be useful in assessing the individual's conscious management of affect in future psychosomatic research.

Update on diagnoses of sexual dysfunctions: controversies surrounding the proposed revisions of existing diagnostic entities and proposed new diagnoses.

The diagnosis of sexual dysfunction(s) or disorder(s) is paramount to the development of the field of sexual medicine. Historically, the diagnoses of these disorders have been considered reliable. The validity of diagnoses of sexual disorders (and the rest of our classification systems) has recently been questioned, especially from the point of clinical utility and homogeneity. This review discusses the issues involved in the development of valid and useful diagnoses of sexual disorders, reviews the proposed changes in the upcoming Diagnostic and Statistical Manual of Mental Disorders, 5th edition, as well as the problems inherent in the revision of this (and any) diagnostic system, and suggests some possible remedies to this process.

Physician staffing for the practice of psychosomatic medicine in general hospitals: a pilot study.

BACKGROUND: The treatment of psychiatric illnesses, prevalent in the general hospital, requires broadly trained providers with expertise at the interface of psychiatry and medicine. Since each hospital operates under different economic constraints, it is difficult to establish an appropriate ratio of such providers to patients. OBJECTIVE: The authors sought to determine the current staffing patterns and ratios of Psychosomatic Medicine practitioners in general hospitals, to better align manpower with clinical service and educational requirements on consultation-liaison psychiatry services. METHOD: Program directors of seven academic Psychosomatic Medicine (PM) programs in the Northeast were surveyed to establish current staffing patterns and patient volumes. Survey data were reviewed and analyzed along with data from the literature and The Academy of Psychosomatic Medicine (APM) fellowship directory. RESULTS: Staffing patterns varied widely, both in terms of the number and disciplines of staff providing care for medical and surgical inpatients. The ratio of initial consultations performed per hospital bed varied from 1.6 to 4.6. CONCLUSION: Although staffing patterns vary, below a minimum staffing level, there is likely to be significant human and financial cost. Efficient sizing of a PM staff must be accomplished in the context of a given institution's patient population, the experience of providers, the presence/absence and needs of trainees, and the financial constraints of the department and institution. National survey data are needed to provide benchmarks for both academic and nonacademic PM services.

Teaching psychiatric residents about paraphilic disorders.

OBJECTIVE: The author describes a program for psychiatric residents in evaluating patients with paraphilic disorders. METHODS: The program curriculum offers clinical education in paraphilic disorders and is organized by various perspectives within psychiatry, including the disease model, the life story, the dimensional perspective, and the behavioral perspective. RESULTS: Graduates of this program generally find this clinical and educational rotation very useful in their future work. CONCLUSION: To develop an effective teaching module for paraphilic disorders, programs need an interested and knowledgeable faculty and an adequate clinical experience.

Effects of progressive muscle relaxation training on anxiety and depression in patients enrolled in an outpatient pulmonary rehabilitation program.

BACKGROUND: This prospective, randomized controlled trial examined the effect of progressive muscle relaxation (PMR) training on anxiety and depression in patients with chronic breathing disorders receiving pulmonary rehabilitation (PR). METHODS: Eighty-three subjects with chronic breathing disorders entering the 8-week PR program were randomly assigned to a standard care or intervention group. The standard program included 2 days per week of exercise, education and psychosocial support delivered by a multidisciplinary team. The intervention group received additional sessions of PMR training using a prerecorded tape for 25 min/week during weeks 2-8. Primary outcome measures were levels of anxiety and depression evaluated by the Hospital Anxiety and Depression Scale. RESULTS: For anxiety, there was an overall significant improvement within each group over time (p < 0.0001). There was no statistically significant group-time interaction (p = 0.17) and no statistically significant difference between the groups (p = 0.22), despite lower scores for every time point in the PMR group. For depression, there was an overall significant improvement within each group over time (p < 0.0001). Although the difference between the groups (p = 0.09) and group-time interaction (p = 0.07) did not reach statistical significance, the results again favored the PMR group for weeks 5-8. Depression scores were lower for the PMR throughout weeks 1-8. CONCLUSIONS: PR is effective in reducing anxiety and depressive level in chronic lung patients. Our findings suggest that adding structured PMR training to a well-established PR program may not confer additional benefit in the further reduction of anxiety and depression in patients receiving PR.

The significance of treating somatic symptoms on functional outcome improvement in patients with major depressive disorder: a post hoc analysis of 2 trials.

BACKGROUND: Functional impairment is associated with major depressive disorder (MDD), and patients with MDD often present with somatic symptoms. OBJECTIVE: To examine the relationships between improved global functioning and core depressive symptoms as well as painful and nonpainful somatic symptoms in patients with MDD. METHOD: This post hoc analysis of 2 identical trials compared the efficacy of duloxetine with that of paroxetine or placebo as treatment of MDD. In the trials, patients with DSM-IV-defined MDD received duloxetine 80 mg/day (N = 188), duloxetine 120 mg/day (N = 196), paroxetine 20 mg/day (N = 183), or placebo (N = 192) for 8 weeks. The Sheehan Disability Scale (SDS), Maier subscale of the 17-item Hamilton Rating Scale for Depression, 21-item Somatic Symptom Inventory, and Visual Analog Scale for overall pain were used to measure functional impairment, core symptoms of depression, and nonpainful and painful somatic symptoms, respectively. Baseline-to-endpoint mean changes in SDS total and subdomains were measured using analysis of variance with last-observation-carried-forward Pearson partial correlations, and path analysis was used to assess the significance of associations and relative contributions of improvement in global functional impairment, depression, and somatic symptoms. The trials were conducted from November 2000 to July 2002. RESULTS: The difference between antidepressant treatment and placebo in SDS total and subdomains was significant (p < .001). At baseline and in change from baseline to endpoint, associations between global functional impairment and core depressive and somatic symptoms were all significant (p < .05). Path analysis demonstrated improvement of functional impairment attributed to treatment effect as 37.0% (core depressive symptoms), 13.0% (nonpainful somatic symptoms), and 11.0% (painful somatic symptoms). CONCLUSION: In patients with MDD, over a third of functional improvement associated with antidepressant therapy was mediated through improvement in core depressive symptoms. In addition, a significant proportion of functional improvement, although to a lesser degree, was associated with the treatment of both nonpainful and painful somatic symptoms.

Update on consultation-liaison psychiatry (psychosomatic medicine).

PURPOSE OF REVIEW: Current issues in consultation-liaison psychiatry, which is now labeled psychosomatic medicine as a formal subspecialty by the American Board of Psychiatry and Neurology, are discussed. RECENT FINDINGS: There is continued interest in how to best manage depression and anxiety in a primary-care setting. Collaborative care that utilizes a psychiatrist within the treatment center, as well as case management by a nurse, have been reviewed and meta-analyses suggest it is an efficient and effective approach. The diagnostic issues within psychosomatic medicine are also an area of concern as the Diagnostic and Statistical Manual of Mental Disorders, 5 edition, is in the planning stages. How to improve both the reliability and validity of somatoform disorders will be a major challenge. Organ transplantation is a clinical challenge for patients, donors and healthcare providers. Issues in assessment and management continue to evolve. Ethical questions also arise due to the shortage of available organs. SUMMARY: Psychosomatic medicine continues to manage patients in medical settings that cut across a continuum from primary-care to complex medical and surgical centers. The clinical problems containing a medical-psychiatric interface offer a clinical challenge but also an area for new knowledge and better interventions.

Development of a new assessment strategy in psychosomatic medicine: the diagnostic criteria for psychosomatic research.

The Diagnostic Criteria for Psychosomatic Research (DCPR) are a diagnostic and conceptual framework that was proposed a decade ago by an international group of investigators. The DCPR's rationale was to translate psychosocial variables that derived from psychosomatic research into operational tools whereby individual patients could be identified. A set of 12 syndromes was developed: health anxiety, thanatophobia, disease phobia, illness denial, persistent somatization, conversion symptoms, functional somatic symptoms secondary to a psychiatric disorder, anniversary reaction, demoralization, irritable mood, type A behavior, and alexithymia. These criteria were meant to be used in a multiaxial approach. The aim of this work is to survey the research evidence which has accumulated on the DCPR, to provide specification for their development and validation and to examine the specific DCPR clusters. Their implications for classification purposes (DSM-V) are also discussed.
