New Strategies in the Assessment of Psychological Factors Affecting Medical Conditions

Study of Rates and Factors Associated to Psychosomatic Syndromes Assessed Using the Diagnostic Criteria for Psychosomatic Research across Different Clinical Settings

INTRODUCTION

Diagnostic Criteria for Psychosomatic Research (DCPR) serve as an instrument for identifying and classifying specific psychosomatic syndromes that are not adequately encompassed in standard nosography. The present study aimed at measuring the prevalence of DCPR syndromes in different clinical settings and exploring factors associated to such diagnoses.

METHODS

A cross-sectional and nationwide study recruited 6,647 patients in different clinical settings: 306 were diagnosed with fibromyalgia (FM), 333 with irritable bowel syndrome, 1,109 with migraine, 2,550 with coronary heart disease (CHD), and 2,349 with type 2 diabetes (T2D). Participants underwent DCPR diagnostic interview and were assessed for depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder 7-Item Scale), and subjective well-being (World Health Organization-5 Well-Being Index). The PsychoSocial Index was used to evaluate global well-being, stress, and abnormal illness behavior. The prevalence of DCPR diagnoses was calculated, and factors associated to such diagnoses were analyzed by logistic regression.

RESULTS

Alexithymia (64.47%), irritable mood (20.55%), and demoralization (15.60%) were the most prevalent psychosomatic syndromes, with demoralization being most common in FM (49.02%). The factors associated to DCPR diagnoses encompassed high anxiety or abnormal illness behavior, and poor well-being. Notably, stress was found to be associated specifically to FM and T2D, with OR of 1.24 (95% CI: 1.06-1.46) and 1.26 (95% CI: 1.18-1.36), respectively.

CONCLUSION

DCPR is a clinically helpful complementary assessment tool in need of being widely implemented in clinical settings in order to have a comprehensive picture of the patients.

A Canadian Survey of Self-Management Strategies and Satisfaction with Ability to Control Pain: Comparison of Community Dwelling Adults with Neuropathic Pain versus Adults with Non-neuropathic Chronic Pain

BACKGROUND

Individuals with chronic pain with neuropathic characteristics (CPNC) describe a different pain experience compared with those with chronic pain without neuropathic characteristics (CP).

AIMS

The aim of this study was to describe and compare pain, self-management strategies, and satisfaction with ability to control pain between adults with CPNC versus CP.

PARTICIPANTS

Seven hundred and ten community-dwelling adults with chronic pain participated in a cross-sectional survey.

METHODS

CPNC was defined as a score ≥12 on the Self-Report Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale. Self-management and pain control was compared between participants with CPNC and CP using frequency, percent, relative risk (RR), odds ratios (ORs), and 95% confidence intervals (CIs).

RESULTS

Participants with CPNC (188/710) reported lower socioeconomic status, poorer general health, and more intense, frequent, and widespread pain. They were more likely to use prescription medications to manage pain (adjusted OR = 2.25, CI = 1.47-3.42). They were more likely to use potentially negative strategies to ease the emotional burden of living with chronic pain, including substance use (adjusted OR = 1.58, CI = 1.06-2.35), denial (adjusted OR = 2.21, CI = 1.49-3.28), and behavioral disengagement (adjusted OR = 1.68, CI = 1.16-2.45), and they were more likely to be completely dissatisfied with their ability to control pain (RR = 1.77, CI = 1.21-2.58).

CONCLUSIONS

Individuals with CPNC have distinct pain and self-management experiences compared with those with CP that may lead to negative coping strategies and dissatisfaction with ability to control pain. Therefore, self-management assessment and support should be tailored by pain condition.

A person-centred approach in medicine to reduce the psychosocial and existential burden of chronic and life-threatening medical illness

The psychiatric, psychosocial, and existential/spiritual pain determined by chronic medical disorders, especially if in advanced stages, have been repeatedly underlined. The right to approach patients as persons, rather than symptoms of organs to be repaired, has also been reported, from Paul Tournier to Karl Jaspers, in opposition and contrast with the technically-enhanced evidence-based domain of sciences that have reduced the patients to 'objects' and weakened the physician's identity deprived of its ethical value of meeting, listening, and treating subjects. The paper will discuss the main psychosocial and existential burden related to chronic and advanced medical illnesses, and the diagnostic and therapeutic implications for a dignity preserving care within a person-centred approach in medicine, examined in terms of care of the person (of the person's whole health), for the person (for the fulfilment of the person's health aspirations), by the person (with physicians extending themselves as total human beings), and with the person (working respectfully with the medically ill person).

A Type A and Type D Combined Personality Typology in Essential Hypertension and Acute Coronary Syndrome Patients: Associations with Demographic, Psychological, Clinical, and Lifestyle Indicators

Many studies have focused on Type A and Type D personality types in the context of cardiovascular diseases (CVDs), but nothing is known about how these personality types combine to create new profiles. The present study aimed to develop a typology of Type A and Type D personality in two groups of patients affected by and at risk for coronary disease. The study involved 711 patients: 51.6% with acute coronary syndrome, 48.4% with essential hypertension (mean age = 56.4 years; SD = 9.7 years; 70.7% men). Cluster analysis was applied. External variables, such as socio-demographic, psychological, lifestyle, and clinical parameters, were assessed. Six groups, each with its own unique combined personality profile scores, were identified: Type D, Type A-Negatively Affected, Not Type A-Negatively Affected, Socially Inhibited-Positively Affected, Not Socially Inhibited, and Not Type A-Not Type D. The Type A-Negatively Affected cluster and, to a lesser extent, the Type D cluster, displayed the worst profile: namely higher total cardiovascular risk index, physical inactivity, higher anxiety and depression, and lower self-esteem, optimism, and health status. Identifying combined personality profiles is important in clinical research and practice in cardiovascular diseases. Practical implications are discussed.

Psychosocial screening and assessment in oncology and palliative care settings

Psychiatric and psychosocial disorders among cancer patients have been reported as a major consequence of the disease and treatment. The problems in applying a pure psychiatric approach have determined the need for structuring more defined methods, including screening for distress and emotional symptoms and a more specific psychosocial assessment, to warrant proper care to cancer patients with psychosocial problems. This review examines some of the most significant issues related to these two steps, screening and assessment of psychosocial morbidity in cancer and palliative care. With regard to this, the many different variables, such as the factors affecting individual vulnerability (e.g., life events, chronic stress and allostatic load, well-being, and health attitudes) and the psychosocial correlates of medical disease (e.g., psychiatric disturbances, psychological symptoms, illness behavior, and quality of life) which are possibly implicated not only in “classical” psychiatric disorders but more broadly in psychosocial suffering. Multidimensional tools [e.g., and specific psychosocially oriented interview (e.g., the Diagnostic Criteria for Psychosomatic Research)] represent a way to screen for and assess emotional distress, anxiety and depression, maladaptive coping, dysfunctional attachment, as well as other significant psychosocial dimensions secondary to cancer, such as demoralization and health anxiety. Cross-cultural issues, such as language, ethnicity, race, and religion, are also discussed as possible factors influencing the patients and families perception of illness, coping mechanisms, psychological response to a cancer diagnosis.

Differentiating cerebral ischemia from functional neurological symptom disorder: a psychosomatic perspective

BACKGROUND

The differential diagnosis of pseudo-neurological symptoms often represents a clinical challenge. The Diagnostic and Statistical Manual of Mental Disorders, DSM-5, made an attempt to improve diagnostic criteria of conversion disorder (functional neurological symptom disorder). Incongruences of the neurological examination, i.e. positive neurological signs, indicate a new approach--whereas psychological factors are not necessary anymore. As the DSM-5 will influence the International Classification of Diseases, ICD-11, this is of importance. In the case presented, a history of psychological distress and adverse childhood experiences coexisted with a true neurological disorder. We discuss the relevance of an interdisciplinary assessment and of operationalized diagnostic criteria.

CASE PRESENTATION

A 32-year-old man presented twice with neurological symptoms without obvious pathological organic findings. A conversion disorder was considered early on at the second admission by the neurology team. Sticking to ICD-10, this diagnosis was not supported by a specialist for psychosomatic medicine, due to missing hints of concurrent psychological distress in temporal association with neurological symptoms. Further investigations then revealed a deep vein thrombosis (though D-dimers had been negative), which had probably resulted in a crossed embolus.

CONCLUSION

The absence of a clear proof of biological dysfunction underlying neurological symptoms should not lead automatically to the diagnosis of a conversion disorder. In contrast, at least in more complex patients, the work-up should include repeated psychological and neurological assessments in close collaboration. According to ICD-10 positive signs of concurrent psychological distress are required, while DSM-5 emphasizes an incongruity between neurological symptoms and neurophysiological patterns of dysfunction. In the case presented, an extensive medical work-up was initially negative, and neither positive psychological nor positive neurological criteria could be identified. We conclude, that, even in times of more sophisticated operationalization of diagnostic criteria, the interdisciplinary assessment has to be based on an individual evaluation of all neurological and psychosocial findings. Prospective studies of inter-rater reliability and validity of psychological factors and positive neurological signs are needed, as evidence for both is limited. With respect to ICD-11, we suggest that positive neurological as well as psychological signs for functional neurological symptom disorder should be considered to increase diagnostic certainty.

Somatization and somatic symptom presentation in cancer: a neglected area

Abstract The recognition of somatization process in cancer patients is a challenging and neglected area, for the extreme difficulty in differentiating and assessing the psycho(patho)logical components from those biologically determined and related to cancer and cancer treatment, as well as for the scarce usefulness of rigid categorical DSM criteria. However, several dimensions of somatization (and the interconnected concept of abnormal illness behaviour) have been shown to be diagnosable in cancer patients and to negatively influence coping and quality of life outcomes. An integration of the formal DSM-ICD nosology with a system specifically taking into account the patients' emotional responses to cancer and cancer treatment, such as the Diagnostic Criteria for Psychosomatic Research (DCPR), is suggested. More data on some specific symptom dimensions, including pain, fatigue and sexual disorders, are needed to examine their possible psychological components. More research is also needed regarding the association of somatization with personality traits (e.g. type D distressed personality, alexithymia), developmental dimensions (e.g. attachment), and cultural issues (e.g. culturally mediated attributional styles to somatic symptoms). Also, the impact and effectiveness of specific therapeutic intervention in 'somatizing' cancer patients is necessary.

Diagnostic criteria for psychosomatic research and somatic symptom disorders

The Diagnostic Criteria for Psychosomatic Research (DCPR) were introduced in 1995 by an international group of investigators to expand the traditional domains of the disease model. The DCPR are a set of 12 'psychosomatic syndromes' which provide operational tools for psychosocial variables with prognostic and therapeutic implications in clinical settings. Eight syndromes concern the main manifestations of abnormal illness behaviour: somatization, hypochondriacal fears and beliefs, and illness denial. The other four syndromes (alexithymia, type A behaviour, demoralization and irritable mood) refer to the domain of psychological factors affecting medical conditions. This review describes the conceptual bases of the DCPR and the main findings concerning their application, with particular reference to the incremental information they added to the customary psychiatric classification. The DCPR were also compared with the provisional DSM-5 somatic symptom disorders. The DCPR were found to be more sensitive than DSM-IV in identifying subthreshold psychological distress and characterizing patients' psychological response to medical illness. DSM-5 somatic symptom disorders seem to neglect important clinical phenomena, such as illness denial, resulting in a narrow view of patients' functioning. The additional information provided by the DCPR may enhance the decision-making process.

Psychosomatic syndromes and anorexia nervosa

BACKGROUND

In spite of the role of some psychosomatic factors as alexithymia, mood intolerance, and somatization in both pathogenesis and maintenance of anorexia nervosa (AN), few studies have investigated the prevalence of psychosomatic syndromes in AN. The aim of this study was to use the Diagnostic Criteria for Psychosomatic Research (DCPR) to assess psychosomatic syndromes in AN and to evaluate if psychosomatic syndromes could identify subgroups of AN patients.

METHODS

108 AN inpatients (76 AN restricting subtype, AN-R, and 32 AN binge-purging subtype, AN-BP) were consecutively recruited and psychosomatic syndromes were diagnosed with the Structured Interview for DCPR. Participants were asked to complete psychometric tests: Body Shape Questionnaire, Beck Depression Inventory, Eating Disorder Inventory-2, and Temperament and Character Inventory. Data were submitted to cluster analysis.

RESULTS

Illness denial (63%) and alexithymia (54.6%) resulted to be the most common syndromes in our sample. Cluster analysis identified three groups: moderate psychosomatic group (49%), somatization group (26%), and severe psychosomatic group (25%). The first group was mainly represented by AN-R patients reporting often only illness denial and alexithymia as DCPR syndromes. The second group showed more severe eating and depressive symptomatology and frequently DCPR syndromes of the somatization cluster. Thanatophobia DCPR syndrome was also represented in this group. The third group reported longer duration of illness and DCPR syndromes were highly represented; in particular, all patients were found to show the alexithymia DCPR syndrome.

CONCLUSIONS

These results highlight the need of a deep assessment of psychosomatic syndromes in AN. Psychosomatic syndromes correlated differently with both severity of eating symptomatology and duration of illness: therefore, DCPR could be effective to achieve tailored treatments.

Type A behaviour: a reappraisal of its characteristics in cardiovascular disease

AIMS

  The role of type A behaviour in cardiovascular disease is controversial and most of the research is based on self-rating scales. The aim of this study was to assess the prevalence of type A behaviour in cardiology and in other medical settings using reliable interview methods that reflect its original description.

METHODS

A sample of 1398 consecutive medical patients (198 with heart transplantation, 153 with a myocardial infarction, 190 with functional gastrointestinal disorders, 104 with cancer, 545 with skin disorders and 208 referred for psychiatric consultation) was administered the Structured Clinical Interview for the DSM-IV and the Structured Interview for the Diagnostic Criteria for Psychosomatic Research (DCPR) which identifies 12 clusters, including type A behaviour.

RESULTS

A cardiac condition was present in 366 patients. There was a significant difference in the prevalence of type A behaviour in cardiovascular disease (36.1%) compared with other medical disorders (10.8%). Type A behaviour frequently occurred together with psychiatric and psychosomatic disturbances, particularly irritable mood, even though in the majority of cases it was not associated with DSM-IV diagnoses. Among cardiac patients, those with type A behaviour were less depressed, demoralised and worried about their illness.

CONCLUSIONS

Type A behaviour was found to occur in about a third of cases of patients with cardiovascular disease. Only in a limited number of cases was it associated with depression. It has a lifestyle connotation that may have important clinical consequences as to stress vulnerability and illness behaviour.

Who listens to our advice? A secondary analysis of data from a clinical trial testing an intervention designed to decrease delay in seeking treatment for acute coronary syndrome

OBJECTIVE

Prolonged prehospital delay in persons experiencing acute coronary syndrome (ACS) remains a problem. Understanding which patients respond best to particular interventions designed to decrease delay time would provide mechanistic insights into the process by which interventions work.

METHODS

In the PROMOTION trial, 3522 at-risk patients were enrolled from 5 sites in the United States (56.4%), Australia and New Zealand; 490 (N=272 intervention, N=218 control) had an acute event within 2 years. Focusing on these 490, we (1) identified predictors of a rapid response to symptoms, (2) identified intervention group subjects with a change in these predictors over 3 months of follow-up, and (3) compared intervention group participants with and without the favorable response pattern. Hypothesized predictors of rapid response were increased perceived control and decreased anxiety. Knowledge, attitudes, and beliefs were hypothesized to differ between responders and non-responders.

RESULTS

Contrary to hypothesis, responders had low anxiety and low perceived control. Only 73 (26.8%) subjects showed this pattern 3 months following the intervention. No differences in ACS knowledge, attitudes, or beliefs were found.

CONCLUSION

The results of this study challenge existing beliefs.

PRACTICE IMPLICATIONS

New intervention approaches that focus on a realistic decrease in anxiety and perceived control are needed.

Anxiety as a context for understanding associations between hypochondriasis, obsessive-compulsive, and panic attack symptoms

In the context of the integrative model of anxiety and depression, we examined whether the essential problem of hypochondriasis is one of anxiety. When analyzed, data from a large nonclinical sample corresponded to the integrative model's characterization of anxiety as composed of both broad, shared and specific, unique symptom factors. The unique hypochondriasis, obsessive-compulsive, and panic attack symptom factors all had correlational patterns expected of anxiety with the shared, broad factors of negative emotionality and positive emotionality. A confirmatory factor analysis showed a higher-order, bifactor model was the best fit to our data; the shared and the unique hypochondriasis and anxiety symptom factors both contributed substantial variance. This study provides refinements to an empirically based taxonomy and clarifies what hypochondriasis is and, importantly, what it is not.

A taxometric study of hypochondriasis symptoms

Hypochondriasis has been conceptualized as both a distinct category that is characterized by a disabling illness preoccupation and as a continuum of health concerns. Empirical support for one of these theoretical models will clarify inconsistent assessment approaches and study designs that have impeded theory and research. To facilitate progress, taxometric analyses were conducted to determine whether hypochondriasis is best understood as a discrete category, consistent with the DSM, or as a dimensional entity, consistent with prevailing opinion and most self-report measures. Data from a large undergraduate sample that completed 3 hypochondriasis symptom measures were factor analyzed. The 4 factor analytically derived symptom indicators were then used in these taxometric analyses. Consistent with our hypotheses and existing theory, results supported a dimensional structure for hypochondriasis. Implications for the conceptualization of hypochondriasis and directions for future study are discussed.

Criteria for psychosomatic research (DCPR) in the medical setting

The Diagnostic Criteria for Psychosomatic Research (DCPR) represent a diagnostic and conceptual framework that aims to translate psychosocial variables derived from psychosomatic research into operational tools whereby individual patients can be identified. A set of 12 syndromes was developed: disease phobia, thanatophobia, health anxiety, illness denial, persistent somatization, functional somatic symptoms secondary to a psychiatric disorder, conversion symptoms, anniversary reaction, irritable mood, type A behavior, demoralization, and alexithymia. The aim of this article is to survey the research evidence that has accumulated on the DCPR in several clinical settings (cardiology, oncology, gastroenterology, endocrinology, primary care, consultation psychiatry, nutrition, and community), to examine prevalence and specific diagnostic clusters of the more prevalent DCPR syndromes, and to review their clinical utility in terms of clinical decision, prediction of psychosocial functioning, and treatment outcomes. The implications for classification purposes (DSM-V) are also discussed.

Comorbidity between common mental disorders and chronic somatic diseases in primary care patients

OBJECTIVE

To estimate the prevalence of the most common mental disorders in primary care patients with chronic somatic diseases based on physicians' diagnoses and compared with healthy probands.

METHOD

A systematic sample of 7940 adult primary care patients was recruited by 1925 general practitioners (GPs) in a large cross-sectional national epidemiological study. The Primary Care Evaluation of Mental Disorders (PRIME-MD) was used as standardized instrument for the assessment of mental disorders. Medical diagnoses were provided by patient's GP.

RESULTS

The prevalence rate of mental disorder was significantly higher in patients with chronic somatic diseases (56.8%) compared with physically healthy subjects (48.9%; OR: 1.37). Prevalence of depressive and anxiety disorders is higher among individuals with neurological, oncological or liver disease. The differences are significant in all comparisons, with the exception of anxiety disorders in patients with musculoskeletal disorders. There is an increase in prevalence rates of mental disorders according to the number of somatic diseases.

CONCLUSIONS

The study provides evidence of the comorbidity of common mental disorders and somatic diseases. We need a predominant focus on affective and anxiety disorders in primary care patients with chronic somatic diseases. Symptoms overlap makes it necessary to discriminate these differences more in detail in future studies.

Psychological predictors of mortality in heart transplanted patients: a prospective, 6-year follow-up study

BACKGROUND

Some reports suggest a link between poor psychological adjustment to heart transplantation and an increased risk of subsequent adverse clinical outcome. Despite its prognostic and therapeutic implications, this issue is still lacking adequate empirical studies. We prospectively tested the predictive value of a complete set of psychiatric and psychological variables, collected with both self-rating and observer-based instruments at midterm after heart transplantation, on the subsequent 6-year survival status.

METHODS

Ninety-five heart transplanted patients underwent the structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders-4th Edition and the structured interview for Diagnostic Criteria for Psychosomatic Research and filled three questionnaires assessing the dimensions of psychological distress, quality of life, and psychological well-being. Demographic characteristics and several clinical parameters were also collected. A 6-year follow-up survival was performed.

RESULTS

Analyses of survival showed that hostility, depression, purpose in life, the occurrence of at least one cardiac event, chronic renal insufficiency, diabetes, number of drug prescriptions, a New York Heart Association (NYHA) class more than or equal to II, and ischemic origin of the cardiopathy significantly predicted subsequent survival duration. When multivariate analyses were performed, high levels of hostility and the presence of diabetes resulted the independent predictors of survival status.

CONCLUSIONS

These findings point out the predictive role of specific components of psychological adjustment to heart transplantation and pose the basis for the evaluation of whether the provision of pharmacologic and psychotherapeutic interventions, aimed at reducing the empirically identified psychological risk factors, may result in a better long-term outcome.

Introduction to the special issue on personality assessment in medical settings

This special issue of the Journal of Personality Assessment brings together 3 review articles and 5 research studies on personality assessment in medical settings that should help clinicians become more familiar with the current status of this field. In 1 review article, Sirri, Fabbri, Fava, and Sonino (2007/this issue) summarize evidence of a new approach to the assessment of psychological syndromes in somatizing patients based on the Diagnostic Criteria for Psychosomatic Research (Fava et al., 1995). The other reviews focus on 2 personality constructs widely used in investigations with medical patients. Kupper and Denollet (2007/this issue) review the Type D personality, whereas Lumley, Neely, and Burger (2007/this issue) provide an overview of alexithymia. Of the research articles, 2 also focus on alexithymia, specifically on the factor structure of the 20-item Toronto Alexithymia Scale (Bagby, Parker, & Taylor, 1994), which is the best-validated and most commonly used measure of alexithymia (Bagby, Taylor, Quilty, & Parker, 2007/this issue; Gignac, Palmer, & Stough, 2007/this issue). The other 3 research studies examine the relationship between specific personality dimensions (behavioral problems relevant to medicine, resiliency, and interpersonal sensitivity) and medical outcomes (adherence to treatment, coping with injury, and postsurgical sexual functioning) from medical samples of patients with HIV, spinal cord injury, and prostate carcinoma (Berry, Elliott, & Rivera, 2007/this issue; Cruess, Meagher, Antoni, & Millon, 2007/this issue; Siegel et al., 2007/this issue). Each article touches on the role person variables can play in the expression of medical problems.
