A cluster analysis-derived classification of psychological distress and illness behavior in the medically ill

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.

Key psychosocial issues in medical care

OBJECTIVE

The aim of this review is to illustrate an innovative framework for assessing the psychosocial aspects of medical disorders within the biopsychosocial model. It is based on clinimetrics, the science of clinical measurements. It may overcome the limitations of DSM-5 in identifying highly individualized responses at the experiential, behavioral, and interpersonal levels.

METHOD

A critical review of the clinimetric formulations of the biopsychosocial model in the setting of medical disease was performed. References were identified through searches from PubMed for English articles on human subjects published from January 1982 to October 2023.

RESULTS

Clinimetric methods of classification have been found to deserve special attention in four major areas: allostatic load (the cumulative cost of fluctuating and heightened neural or neuroendocrine responses to environmental stressors); health attitudes and behavior; persistent somatization; demoralization and irritable mood. This type of assessment, integrated with traditional psychiatric nosography, may disclose pathophysiological links and provide clinical characterizations that demarcate major prognostic and therapeutic differences among patients who otherwise seem deceptively similar because they have the same medical diagnosis. It may be of value in a number of medical situations, such as: high level of disability or compromised quality of life in relation to what is expected by disease status; delayed or partial recovery; insufficient participation in self-management and/or rehabilitation; failure to resume healthy role after convalescence; unhealthy lifestyle; high attendance of medical facilities disproportionate to detectable disease; lack of treatment adherence; illness denial.

CONCLUSIONS

The clinimetric approach to the assessment of key psychosocial variables may lead to unique individual profiles, that take into account both biology and biography. It may offer new opportunities for integrating psychosocial and medical perspectives.

Fatigue as Mediator Factor in PTSD-Symptoms after Allogeneic Hematopoietic Stem Cell Transplantation

BACKGROUND

Allogeneic Hematopoietic Stem Cell Transplantation (HSCT) is a valid treatment for hematological oncological or metabolic diseases. Despite its therapeutic efficacy, it is an aggressive treatment that impacts negatively on quality of life (QoL) and may result in Post-Traumatic Stress Disorder (PTSD) symptoms. The aim of this study is to explore rates and risk factors for PTSD symptoms, and fatigue in post-HSCT patients with hematological malignancies.

METHODS

A total of 123 patients after HSCT were evaluated for PTSD symptoms, QoL and fatigue. PTSD symptoms were assessed with the Impact of Event Scale- Revised (IES-R), QoL was measured with Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) and fatigue symptoms were assessed with Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F).

RESULTS

A total of 58.54% of the sample developed PTSD symptoms after transplant. Patients with PTSD symptoms reported significantly lower QoL total scores and significantly higher fatigue than those without PTSD symptoms (p < 0.001). The SEM analysis showed that worse QoL and fatigue affected PTSD symptomatology along different pathways. Fatigue was found as a major influencing factor of PTSD symptoms directly (β = 0.31 **), while QoL only through the mediation of fatigue at a lesser extent. (β = 0.33 *).

CONCLUSIONS

Our findings indicate that QoL is a concurrent causative factor to the development of PTSD symptomatology through the mediating role of fatigue. Innovative interventions before transplantation to prevent PTSD symptoms should be investigated to improve survival and QoL in patients.

Clinical utility of demoralization: A systematic review of the literature

Demoralization is a complex clinical phenomenon which has raised a growing interest in clinical and research realms. The present systematic review of the literature aimed at (1) updating on demoralization prevalence in different populations, (2) identifying the instruments more largely used to assess demoralization, and (3) verifying whether new tools of assessment have been proposed. PubMed and Web of Science were searched from inception to April 2022. Search terms were: demoralization/demoralized/demoralizing/demoralised/demoralising. PRISMA guidelines were followed. GRADE rating system was used. A total of 188 papers were included. Demoralization appeared to be a distinctive psychological state common in medical, psychiatric, and non-clinical settings, thus not limited to life-threatening diseases. Diagnostic Criteria for Psychosomatic Research (DCPR) and Demoralization Scale (DS) are the most commonly used tools to assess it. DCPR allow to diagnose demoralization as a manifestation of dealing with chronic stress. DS captures dimensionally a psychological distress related to end of life. Demoralization is associated with clinical features encompassing allostatic overload, quality of life, wellbeing/euthymia. Implications on health outcomes and treatment are discussed. Demoralization warrants careful consideration in clinical contexts through valid assessment procedures. DCPR are recommended to diagnose it, DS can be helpful to capture clinical details.

Exploring and assessing demoralization in patients with non-psychotic affective disorders

BACKGROUND

Demoralization, as assessed through the Diagnostic Criteria for Psychosomatic Research-Demoralization (DCPR/D) interview or the Demoralization Scale (DS), has been found to affect about 30% of patients with medical disorders, while few studies have been done in patients with psychiatric disorders.

METHODS

A convenience sample of 377 patients with ICD-10 diagnoses of mood, anxiety, stress-related disorders or other non-psychotic disorders was recruited from two Italian university psychiatry centers. The DCPR/D interview and the Italian version of the DS (DS-IT) were used to assess demoralization and the Patient Health Questionnaire-9 (PHQ-9) to assess depression.

RESULTS

Demoralization was diagnosable in more than 50% of the patients. Factor analysis of the DS-IT indicated four main factors, Meaninglessness/Helplessness, Disheartenment, Dysphoria and Sense of Failure, explaining 62% of the variance of the scale. Patients with bipolar or unipolar major depression and personality disorders had the highest prevalence of demoralization (DCPR/D) and the highest scores on all the DS-IT factors in comparison with patients with adjustment or anxiety disorders. About 50% of patients with moderate demoralization (DS-IT) were not clinically depressed (PHQ-9 <10), while almost all with severe demoralization were depressed.

LIMITATIONS

Prospective studies on larger samples with other psychiatric disorders, also taking into account subjective incompetence, are needed. Since the DCPR/D assesses demoralization as a categorical construct, a dimensional framework should be necessary.

CONCLUSIONS

The findings enrich the research on demoralization, showing for the first time the importance of this construct, as measured by the DCPR/D and the DS-IT, in patients with psychiatric disorders.

The Use of Demoralization Scale in Italian Kidney Transplant Recipients

Demoralization is a commonly observed syndrome in medically ill patients. The risk of demoralization may increase in patients after a kidney transplant (KTRs) because of the stressful nature of renal transplantation, psychosocial challenges, and adjustment needs. No study is available on demoralization amongst KTRs. The purpose of our study was to evaluate the validity of the Italian version of the Demoralization Scale (DS-IT) and the prevalence of demoralization in KTRs. Also, we aimed at exploring the association of the DS-IT with International Classification of Diseases (ICD) psychiatric diagnoses, post-traumatic growth (PTG), psychological and physical symptoms, and daily-life problems. A total of 134 KTRs were administered the MINI International Neuropsychiatric Interview 6.0. and the Diagnostic Criteria for Psychosomatic Research-Demoralization (DCPR/D) Interview. The DS-IT, the Edmonton Symptom Assessment System (ESAS), the Canadian Problem Checklist (CPC), were used to measure demoralization, physical and psychological symptoms, and daily-life problems; also, positive psychological experience of kidney transplantation was assessed with the PTG Inventory. Routine biochemistry and sociodemographic data were collected. Exploratory factor analysis demonstrated a four-dimensional factor structure of the DS-IT, explaining 55% of the variance (loss of meaning and purpose, disheartenment, dysphoria, and sense of failure). DS-IT Cronbach alpha coefficients indicated good or acceptable level of internal consistency. The area under the Receiving Operating Characteristics (ROC) curve for DS-IT (against the DCPR/D interview as a gold standard) was 0.92. The DS-IT optimal cut-off points were ≥20 (sensitivity 0.87, specificity 0.82). By examining the level of demoralization, 14.2%, 46.3%, 24.6%, and 14.6% of our sample were classified as having no, low, moderate, and high demoralization, respectively, with differences according to the ICD psychiatric diagnoses (p < 0.001). DS-IT Total and subscales scores were positively correlated with scores of ESAS symptoms and CPC score. A correlation between DS-IT loss of meaning and purpose subscale and PTGI appreciation of life subscale (p < 0.05) was found. This study shows, for the first time, a satisfactory level of reliability of the DS-IT and a high prevalence of severe demoralization in KTRs.

Assessing demoralization in medically ill patients: Factor structure of the Italian version of the demoralization scale and development of short versions with the item response theory framework

OBJECTIVE

Demoralization has been mostly investigated in oncology but is also relevant for patients with other physical illnesses. Our aims were to investigate the psychometric properties of the 24-item Italian version of the Demoralization Scale (DS-24) among medically ill inpatients, and to develop shorter versions for screening.

METHODS

Four-hundred and seventy-three participants were recruited from medical wards of the University Hospital of Ferrara. Patients were assessed using the Diagnostic Criteria for Psychosomatic Research-Demoralization module (DCPR/D), Demoralization Scale (DS-24), Patient Health Questionnaire-9 (PHQ-9), Brief-Symptom Inventory-18, Anxiety subscale (BSI-Anx) and EuroQol Group (EQ-5D). Confirmatory factor analyses of previous structures and exploratory factor analyses were conducted using an Item Response Theory approach, including a bifactor model.

RESULTS

According to DCPR/D criteria, the prevalence of demoralization was 40%. Confirmatory analyses revealed that none out of seven factor structures from oncology studies adequately fitted data from hospital inpatients. Exploratory Item Factor Analysis uncovered a four-factor model comprising Disheartenment, Dysphoria, Sense of Failure, Loss of Meaning and Purpose, or a bifactor model, comprising similar factors with the addition of a general factor accounting for 45% of the variance. Moreover, we developed 13 and 6-item versions of the DS, both retaining high correlation with DS-24 scores (r = 0.98 and r = 0.95, respectively) and concordance with DCPR/D criteria (AUC-ROC 0.82 and 0.81).

CONCLUSION

The DS factor structure differs between general hospital and cancer patients. Differences may depend on intrinsic disease features and cultural-geographic factors. The short versions of the DS-24 may aid clinicians in identifying demoralized patients in hospital settings.

Impact of Depression and Demoralization on Blood Pressure Control in African Americans with Hypertension: Findings from the TRIUMPH Trial

BACKGROUND

African Americans develop hypertension earlier and have worse cardiovascular outcomes than Caucasians. Accumulating evidence suggests that psychological distress may play a role in the observed racial differences in hypertension. Several studies have investigated the relationship between depression and hypertension while little is still known about the role of demoralization.

METHODS

Using data from the Trial Using Motivational Interviewing, Positive Affect, and Self-affirmation in African Americans with Hypertension (TRIUMPH), logistic regression models were used to estimate differences in blood pressure control at 12 months among participants with demoralization, depression, and both conditions.

RESULTS

Our logistic models showed that reported psychosocial symptoms significantly differed in predicting success in blood pressure control at 12 months. Contrast analyses showed that, after adjusting for sociodemographic, clinical, and psychosocial variables, demoralized patients were less likely to achieve blood pressure control than participants without affective conditions (p = 0.020). Similar results emerged for patients with depression (p = 0.042) and both conditions (p = 0.022).

CONCLUSIONS

Depression can be extremely debilitating and has serious health consequence. Our findings confirm this result and show that, even though depression and demoralization share common features, they are two distinct clinical phenomena with similar negative impact on blood pressure control in African Americans.

The burden of psychosocial morbidity related to cancer: patient and family issues

With cancer incidence increasing over time, attention to the burden of related psychiatric and psychosocial consequences of the disease and treatment is a major topic for both cancer patients and their caregivers. Among cancer patients, psychiatric (e.g. adjustment, anxiety, depressive disorders) and neuropsychiatric disorders (e.g. cognitive disorders secondary to treatment, delirium) have been shown to affect an average of 30-35% patients, with differences according to stage and type of cancer. Also other psychosocial syndromes (e.g. demoralization, health anxiety, irritable mood) not taken into account in usual nosological systems should be considered for their impact on the patient's quality-of-life. Also, it has been repeatedly reported that psychological distress reverberates substantially throughout the nuclear family, and that a family approach is necessary in cancer care, with the caregiver-patient dyad as a unit to be the focus and direction of assessment and intervention. In this review the most significant psychosocial disorders causing burden for cancer patients and their caregivers are examined, and the main methods of assessment for more proper referral and treatment are summarized.

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).

Current Psychosomatic Practice

Psychosomatic research has advanced over the past decades in dealing with complex biopsychosocial phenomena and may provide new effective modalities of patient care. Among psychosocial variables affecting individual vulnerability, course, and outcome of any medical disease, the role of chronic stress (allostatic load/overload) has emerged as a crucial factor. Assessment strategies include the Diagnostic Criteria for Psychosomatic Research. They are presented here in an updated version based on insights derived from studies carried out so far and encompass allostatic overload, type A behavior, alexithymia, the spectrum of maladaptive illness behavior, demoralization, irritable mood, and somatic symptoms secondary to a psychiatric disorder. Macroanalysis is a helpful tool for identifying the relationships between biological and psychosocial variables and the individual targets for medical intervention. The personalized and holistic approach to the patient includes integration of medical and psychological therapies in all phases of illness. In this respect, the development of a new psychotherapeutic modality, Well-Being Therapy, seems to be promising. The growth of subspecialties, such as psychooncology and psychodermatology, drives towards the multidisciplinary organization of health care to overcome artificial boundaries. There have been major transformations in health care needs in the past decades. From psychosomatic medicine, a land of innovative hypotheses and trends, many indications for changes in the current practice of medicine are now at hand. The aim of this critical review is to outline current and potential clinical applications of psychosomatic methods.

How to Define Pathogenicity, Health, and Disease?

Scientific and clinical communities produce ever increasing amounts of data and details about health and disease. Our ability to understand and utilize this information is limited because of imprecise language and lack of well-defined concepts. This problem involves also the principal concepts of health, disease, and pathogenicity. Here, a systematic model is presented for pathogenicity, as well as for health and disease. It has three components: extent, modulation, and severity, which jointly define the continuum of pathogenicity. The model is population based, and once implemented, it can be used for numerous purposes such as diagnosis, patient stratification, prognosis, finding phenotype-genotype correlations, or explaining adverse drug reactions. The new model has several benefits including health economy by allowing evidence-based personalized/precision medicine.

The clinical inadequacy of the DSM-5 classification of somatic symptom and related disorders: an alternative trans-diagnostic model

The Diagnostic and Statistical of Mental Disorders, Fifth Edition (DSM-5) somatic symptom and related disorders chapter has a limited clinical utility. In addition to the problems that the single diagnostic rubrics and the deletion of the diagnosis of hypochondriasis entail, there are 2 major ambiguities: (1) the use of the term "somatic symptoms" reflects an ill-defined concept of somatization and (2) abnormal illness behavior is included in all diagnostic rubrics, but it is never conceptually defined. In the present review of the literature, we will attempt to approach the clinical issue from a different angle, by introducing the trans-diagnostic viewpoint of illness behavior and propose an alternative clinimetric classification system, based on the Diagnostic Criteria for Psychosomatic Research.

Neural Correlates of Three Promising Endophenotypes of Depression: Evidence from the EMBARC Study

Major depressive disorder (MDD) is clinically, and likely pathophysiologically, heterogeneous. A potentially fruitful approach to parsing this heterogeneity is to focus on promising endophenotypes. Guided by the NIMH Research Domain Criteria initiative, we used source localization of scalp-recorded EEG resting data to examine the neural correlates of three emerging endophenotypes of depression: neuroticism, blunted reward learning, and cognitive control deficits. Data were drawn from the ongoing multi-site EMBARC study. We estimated intracranial current density for standard EEG frequency bands in 82 unmedicated adults with MDD, using Low-Resolution Brain Electromagnetic Tomography. Region-of-interest and whole-brain analyses tested associations between resting state EEG current density and endophenotypes of interest. Neuroticism was associated with increased resting gamma (36.5-44 Hz) current density in the ventral (subgenual) anterior cingulate cortex (ACC) and orbitofrontal cortex (OFC). In contrast, reduced cognitive control correlated with decreased gamma activity in the left dorsolateral prefrontal cortex (dlPFC), decreased theta (6.5-8 Hz) and alpha2 (10.5-12 Hz) activity in the dorsal ACC, and increased alpha2 activity in the right dlPFC. Finally, blunted reward learning correlated with lower OFC and left dlPFC gamma activity. Computational modeling of trial-by-trial reinforcement learning further indicated that lower OFC gamma activity was linked to reduced reward sensitivity. Three putative endophenotypes of depression were found to have partially dissociable resting intracranial EEG correlates, reflecting different underlying neural dysfunctions. Overall, these findings highlight the need to parse the heterogeneity of MDD by focusing on promising endophenotypes linked to specific pathophysiological abnormalities.

Does It Matter Who Provides Psychological Interventions for Medically Unexplained Symptoms? A Meta-Analysis

BACKGROUND

Patients with medically unexplained symptoms (MUS) are difficult to treat and cause high health-care costs. Psychological interventions might be a beneficial option for treating patients with MUS, but evidence is inconsistent. This meta-analysis compares the effectiveness of psychological interventions for MUS - delivered either by psychotherapists (PTs) or by general practitioners (GPs) - with that of usual care.

METHOD

We conducted a systematic review and meta-analysis on randomised controlled trials of psychological interventions for MUS. Physical symptoms were the primary outcome, and physical functioning and psychological symptoms were the secondary outcomes. We pooled between-group effect sizes (ESs) after the treatment and at the follow-up in random-effects meta-regressions and stratified meta-analyses. We repeated these analyses with the intervention provider, intervention dose, MUS severity and methodological quality as predictors of relative intervention effects.

RESULTS

A total of 3,225 patients in 20 studies were analysed. After the treatment, small and significant ESs were found for all 3 outcome domains (ES range: 0.13-0.19, all p < 0.05). Psychological interventions were more beneficial for physical symptoms when delivered by PTs than by GPs (p = 0.02). There was no difference between PTs and GPs in terms of physical functioning and psychological symptoms.

CONCLUSION

Psychological interventions are effective for patients with MUS, but the effects are small and most likely of short duration. Interventions that are delivered by PTs appear to have larger effects on unexplained physical symptoms than those delivered by GPs. Whether this superiority is due to a larger number of sessions of PT interventions remains unclear from our findings.

Consultation-Liaison Psychiatry in the General Hospital: the Experience of UK, Italy, and Japan

Consultation-liaison psychiatry (CLP) is a psychiatric subspecialty addressing the psychological care of medically ill patients as well as the relationship between medical and psychiatric disorders. As a specialty, it has developed over the last 30 years. Yet several cultural and organizational problems in different countries have emerged, including differences regarding implementing CLP services and in the application of CLP guidelines. This paper examines the progress and challenges of CLP in three culturally diverse countries: the UK, Italy, and Japan. In all three countries, the provision of CLP service remains insufficient, and the application of officially acknowledged standards of care is necessary.

Demoralization: a systematic review on its clinical characterization

BACKGROUND

Demoralization has been described as a psychological state characterized by helplessness, hopelessness, a sense of failure and the inability to cope.

METHODS

We conducted a systematic review with qualitative data analysis following PRISMA criteria with the following aims: to review validated assessment instruments of the demoralization syndrome, report main findings regarding demoralization as measured by validated instruments that emerge in the literature, compare and report evidence for the clinical utility of the identified instruments. Utilizing the key word 'demoralization' in PubMed and PsycINFO databases, an electronic search was performed, supplemented by Web of Science and manual searches. Study selection criteria included the assessment of medical patients and use of instruments validated to assess demoralization. Seventy-four studies were selected.

RESULTS

Four instruments emerged in the literature. Main findings concern prevalence rates of demoralization, evidence of discriminant validity from major depression, factors associated with demoralization and evidence of clinical utility. The instruments vary in their definition, the populations they aim to assess, prevalence rates they estimate and their ability to discriminate between different conditions. Nonetheless, demoralization appears to be a distinctive psychological state characterized by helplessness, hopelessness, giving up and subjective incompetence. It is not limited to life-threatening diseases such as cancer, but may occur in any type of clinical situation. It is associated with stress and adverse health outcomes.

CONCLUSIONS

Studies addressing the incremental value of demoralization in psychiatry and psychology are needed. However, demoralization appears to entail specific clinical features and may be a distinct condition from major depression.

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.

Post-traumatic growth in breast cancer survivors: new insights into its relationships with well-being and distress

Research investigating possible relations between Post-traumatic growth (PTG) and clinical indexes--such as psychosocial distress, physical and psychological well-being--is lacking in medical settings. The aim of this study was to look into such relationships in breast cancer survivors (Bcs) and in healthy control subjects who experienced other stressful events. Sixty Bcs and 60 healthy women reporting other stressful events were compared according to the following scales: Post-traumatic Growth Inventory, Psychological Well-being Scales (PWB), Symptom Questionnaire and Psychosocial Index. Bcs reported significantly higher levels of PTG and distress, and lower levels of PWB compared to healthy women. Bcs with high levels of PTG showed increased levels of physical well-being and decreased distress. Healthy women under stressful circumstances reporting high levels of PTG showed increased levels of PWB. PTG levels were higher in Bcs and associated with decreased psychological distress and somatisation. These results carry important implications for clinical assessment, as well as for planning interventions to improve well-being and resilience in oncology.

Alexithymia in the medically ill. Analysis of 1190 patients in gastroenterology, cardiology, oncology and dermatology

OBJECTIVE

To use the Diagnostic Criteria for Psychosomatic Research (DCPR) for characterizing alexithymia in a large and heterogeneous medical population, in conjunction with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) and other DCPR criteria.

METHOD

Of 1305 patients recruited from 4 medical centers in the Italian Health System, 1190 agreed to participate. They all underwent an assessment with DSM-IV and DCPR structured interviews. A total of 188 patients (15.8%) were defined as alexithymic by using the DCPR criteria. Data were submitted to cluster analysis.

RESULTS

Five clusters of patients with alexithymia were identified: (1) alexithymia with no psychiatric comorbidity (29.3% of cases); (2) depressed somatization with alexithymic features (23.4%); (3) alexithymic illness behavior (17.6%); (4) alexithymic somatization (17%) and (5) alexithymic anxiety (12.8%).

CONCLUSIONS

The results indicate that DCPR alexithymia is associated with a comorbid mood or anxiety disorder in about one third of cases; it is related to various forms of somatization and abnormal illness behavior in another third and may occur without psychiatric comorbidity in another subgroup. Identification of alexithymic features may entail major prognostic and therapeutic differences among medical patients who otherwise seem to be deceptively similar since they share the same psychiatric and/or medical diagnosis.

Assessing psychological factors affecting medical conditions: comparison between different proposals

OBJECTIVE

We compared the provisional Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for Somatic Symptom Disorders (SSD) and an alternative classification based on the Diagnostic Criteria for Psychosomatic Research (DCPR) as to prevalence and associations with dimensional measures of psychological distress and functioning in a population of medical patients.

METHOD

Seventy consecutive outpatients with congestive heart failure were administered an ad hoc structured clinical interview for the identification of DSM-5 SSD, the section concerning hypochondriasis of the Structured Clinical Interview for DSM-IV, the Structured Interview for DCPR and Paykel's Clinical Interview for Depression. Subjects also completed the Symptom Questionnaire and the Psychosocial Index. Global assessment of functioning was performed with the DSM-IV Axis V.

RESULTS

A diagnosis within DSM-5 SSD was found in 13 patients (18.5%): 61.5% of them were diagnosed with the Psychological Factors Affecting Medical Condition category. Twenty-nine patients (41.4%) were classified according to the DCPR-based proposal: illness denial, demoralization and irritable mood were the most frequent specifiers. The DCPR-based classification showed a greater number of significant associations with dimensional measures of psychological distress, global functioning and stress.

CONCLUSION

Compared to DSM-5 SSD, the DCPR-based proposal was more sensitive in detecting psychological factors relevant to illness course and provided a better characterization of such factors. The DCPR-based proposal was also superior in identifying patients with increased psychological distress and poor psychosocial functioning.

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.
