Incorporating biopsychosocial characteristics into personalized healthcare: a clinical approach

Health Communication Preferences of Transgender and Gender-Diverse Individuals - Development and First Psychometric Evaluation of the CommTrans Questionnaire

Patient-doctor communication is an important component of patient-centered care and should be adapted to the target group. Adapting communication to transgender and gender-diverse individuals is particularly difficult, as little is known about the preferences of this group. Thus, the aim of the study was to develop a questionnaire to assess the communication preferences of the target group. Based on a qualitative study, an item pool was created, which was tested in a survey in September 2022. An item analysis was conducted and items with unacceptable characteristics were removed. The remaining item pool was examined with an explorative factor analysis. The sample consisted of N = 264 individuals. Of the initial k = 43 items, k = 9 items remained in the final factor analysis. The final two factor solution explained 60.7% of the variance. The factors describe the emotional resonance in communication (Cronbach's α = .74; e.g. "My medical doctors should be happy for me when my treatment progresses positively.") as well as gender-related communication (Cronbach's α = .85; e.g. "My medical doctors should introduce themselves with pronouns."). Overall, the questionnaire captures the communication preferences of transgender and gender-diverse individuals in medical conversations. It covers two important topics for the target group, but further validation is necessary.

Guide Development for eHealth Interventions Targeting People With a Low Socioeconomic Position: Participatory Design Approach

BACKGROUND

People with a low socioeconomic position (SEP) are less likely to benefit from eHealth interventions, exacerbating social health inequalities. Professionals developing eHealth interventions for this group face numerous challenges. A comprehensive guide to support these professionals in their work could mitigate these inequalities.

OBJECTIVE

We aimed to develop a web-based guide to support professionals in the development, adaptation, evaluation, and implementation of eHealth interventions for people with a low SEP.

METHODS

This study consisted of 2 phases. The first phase involved a secondary analysis of 2 previous qualitative and quantitative studies. In this phase, we synthesized insights from the previous studies to develop the guide's content and information structure. In the second phase, we used a participatory design process. This process included iterative development and evaluation of the guide's design with 11 professionals who had experience with both eHealth and the target group. We used test versions (prototypes) and think-aloud testing combined with semistructured interviews and a questionnaire to identify design requirements and develop and adapt the guide accordingly.

RESULTS

The secondary analysis resulted in a framework of recommendations for developing the guide, which was categorized under 5 themes: development, reach, adherence, evaluation, and implementation. The participatory design process resulted in 16 requirements on system, content, and service aspects for the design of the guide. For the system category, the guide was required to have an open navigation strategy leading to more specific information and short pages with visual elements. Content requirements included providing comprehensible information, scientific evidence, a user perspective, information on practical applications, and a personal and informal tone of voice. Service requirements involved improving suitability for different professionals, ensuring long-term viability, and a focus on implementation. Based on these requirements, we developed the final version of "the inclusive eHealth guide."

CONCLUSIONS

The inclusive eHealth guide provides a practical, user-centric tool for professionals aiming to develop, adapt, evaluate, and implement eHealth interventions for people with a low SEP, with the aim of reducing health disparities in this population. Future research should investigate its suitability for different end-user goals, its external validity, its applicability in specific contexts, and its real-world impact on social health inequality.

"What matters to you?": The relevance of patient priorities in dialysis care for assessment and clinical practice

BACKGROUND

Dialysis patients are confronted with numerous, complex problems, which make it difficult to identify individual patient's most prominent problems. The objectives of this study were to (1) identify dialysis patients' most prominent problems from a patient perspective and (2) to calculate disease-specific norms for questionnaires measuring these problems.

METHODS

One hundred seventy-five patients treated with hemodialysis or peritoneal dialysis completed a priority list on several domains of functioning (e.g., physical health, mental health, social functioning, and daily activities) and a set of matching questionnaires assessing patient functioning on these domains. Patient priorities were assessed by calculating the importance ranking of each domain on the priority list. Subsequently, disease-specific norm scores were calculated for all questionnaires, both for the overall sample and stratified by patient characteristics.

RESULTS

Fatigue was listed as patients' most prominent problem. Priorities differed between male and female patients, younger and older patients, and home and center dialysis patients, which was also reflected in their scores on the corresponding domains of functioning. Therefore, next to general norm scores, we calculated corrections to the general norms to take account of patient characteristics (i.e., sex, age, and dialysis type).

CONCLUSIONS

Results highlight the importance of having attention for the specific priorities and needs of each individual patient. Adequate disease-specific, norm-based assessment is not only necessary for diagnostic procedures but is an essential element of patient-centered care: It will help to better understand and respect individual patient needs and tailor treatment accordingly.

eHealth to Improve Psychological Functioning and Self-Management of People With Chronic Kidney Disease: A Randomized Controlled Trial

OBJECTIVE

Psychological distress is common among patients with chronic kidney disease and can interfere with disease self-management. We assessed the effectiveness of the personalized E-GOAL electronic health care pathway with screening and cognitive-behavioral therapy including self-management support, aimed to treat psychological distress and facilitate self-management among people with chronic kidney disease not on dialysis ( N = 121).

METHODS

Primary outcome of the open two-arm parallel randomized controlled trial in four Dutch hospitals was psychological distress at posttest directly after the intervention and at 3-month follow-up. Secondary outcomes were physical and mental health-related quality of life, self-efficacy, chronic disease self-management, and personalized outcomes, that is, perceived progress compared with the previous time point on functioning (e.g., mood or social functioning) and self-management (e.g., dietary or medication adherence) outcomes that were prioritized by each individual.

RESULTS

Linear mixed-effects analyses showed no significant time-by-group interaction effects for psychological distress, health-related quality of life, self-efficacy, and chronic condition self-management, whereas analyses of covariance showed significantly more perceived progress in the intervention group at posttest on personally prioritized areas of functioning ( b = 0.46, 95% confidence interval = 0.07-0.85) and self-management ( b = 0.55, 95% confidence interval = 0.16-0.95), with Cohen d values of 0.46 and 0.54 (medium effects), respectively. Effects on personalized outcomes were maintained at follow-up.

CONCLUSIONS

Compared with regular care only, the electronic health intervention did not reduce psychological distress, whereas personalized outcomes did improve significantly after intervention. Future studies could consider personalized outcomes that reflect individually relevant areas and treatment goals, matching person-tailored treatments.

E-HEalth treatment in Long-term Dialysis (E-HELD): study protocol for a multicenter randomized controlled trial evaluating personalized Internet-based cognitive-behavioral therapy in dialysis patients

Background

Kidney failure and dialysis treatment have a large impact on a patient’s life. Patients experience numerous, complex symptoms and usually have multiple comorbid conditions. Despite the multitude of problems, patients often have priorities for improvement of specific aspects of their functioning, which would be helpful for clinicians to become informed of. This highlights a clear need for patient-centered care in this particular patient group, with routine screening as a vital element to timely recognize symptoms and tailored treatment to match individual patients’ needs and priorities. By also providing feedback on patient’s screening results to the patient itself, the patient is empowered to actively take control in one’s mostly uncontrollable disease process. The current paper describes the study design of a multicenter randomized controlled trial evaluating the effectiveness of the “E-HEealth treatment in Long-term Dialysis” (E-HELD) intervention. This therapist-guided Internet-based cognitive-behavioral therapy (ICBT) intervention is focused on and personalized to the myriad of problems that dialysis patients experience and prioritize.

Methods

After a screening procedure on adjustment problems, 130 eligible dialysis patients will be randomized to care as usual or the E-HELD intervention. Patients will complete questionnaires on distress (primary outcome measure), several domains of functioning (e.g., physical, psychological, social), potential predictors and mediators of treatment success, and the cost-effectiveness of the intervention, at baseline, 6-month follow-up, and 12-month follow-up. In addition, to take account of the personalized character of the intervention, the Personalized Priority and Progress Questionnaire (PPPQ) will be administered which is a personalized instrument to identify, prioritize, and monitor individual problems over time.

Discussion

The present study design will provide insight in the effectiveness of tailored ICBT in patients with kidney failure who are treated with dialysis. When proven effective, the screening procedure and the subsequent ICBT intervention could be implemented in routine care to detect, support, and treat patients struggling with adjustment problems.

Guided internet-based cognitive-behavioral therapy for patients with rheumatic conditions: A systematic review

CONTEXT

Rheumatic conditions have a large impact on both patients and society. Many patients experience adjustment problems, such as symptoms of anxiety and depression and sleep problems, contributing to high healthcare costs. Internet-based cognitive-behavioral therapy (iCBT) has shown to support patients with somatic conditions in coping with their disease, with therapist-guided iCBT usually showing larger effects than unguided iCBT. However, the specific relevance of guided iCBT for rheumatic conditions has not been reviewed yet, which could have important implications for implementation.

OBJECTIVES

The objective of our review was to give an overview of evaluations of guided iCBT for rheumatic conditions, including physical, psychological, and impact on daily life outcomes.

METHODS

This review is registered with PROSPERO with registration number CRD42020154911. The review followed PRISMA guidelines and included an assessment of risk of bias. PubMed, PsycINFO, Embase, Cochrane Library, Web of Science, and Emcare were searched until 5 October 2020. Inclusion criteria were: patients ≥18 years old with a rheumatic condition, randomized controlled trial, accessible full-text English article, original data, inclusion of psychological, and/or physical and/or impact outcomes, and therapist-guided iCBT. Study and sample characteristics, as well as clinical variables were extracted.

RESULTS

A systematic search identified 6089 studies, of which 8 trials were included, comprising of 1707 participants in total. Significant medium to large between-group effects were found for psychological outcomes (depression, anxiety, catastrophizing, self-efficacy) and impact on daily life outcomes (impact on daily life, quality of life), whilst results for physical outcomes (pain intensity, fatigue) were mixed.

CONCLUSION

Whilst more research is warranted, for instance regarding physical outcomes, cost-effectiveness, safety of the intervention, and moderators of iCBT success, our results show that guided iCBT could be an important addition to medical treatment for rheumatic conditions. Guided iCBT can improve psychological and impact on daily life outcomes in patients with rheumatic conditions, which is promising for iCBT implementation in clinical practice.

Detecting and Treating Psychosocial and Lifestyle-Related Difficulties in Chronic Disease: Development and Treatment Protocol of the E-GOAL eHealth Care Pathway

Many patients with lifestyle-related chronic diseases find it difficult to adhere to a healthy and active lifestyle, often due to psychosocial difficulties. The aim of the current study was to develop an eHealth care pathway aimed at detecting and treating psychosocial and lifestyle-related difficulties that fits the needs and preferences of individual patients across various lifestyle-related chronic diseases. Each intervention component was developed by (1) developing initial versions based on scientific evidence and/or the Behavior Change Wheel; (2) co-creation: acquiring feedback from patients and health professionals; and (3) refining to address users' needs. In the final eHealth care pathway, patients complete brief online screening questionnaires to detect psychosocial and lifestyle-related difficulties, i.e., increased-risk profiles. Scores are visualized in personal profile charts. Patients with increased-risk profiles receive complementary questionnaires to tailor a 3-month guided web-based cognitive behavioral therapy intervention to their priorities and goals. Progress is assessed with the screening tool. This systematic development process with a theory-based framework and co-creation methods resulted in a personalized eHealth care pathway that aids patients to overcome psychosocial barriers and adopt a healthy lifestyle. Prior to implementation in healthcare, randomized controlled trials will be conducted to evaluate its cost-effectiveness and effectiveness on psychosocial, lifestyle, and health-related outcomes.

An Internet-Based Psychological Intervention With a Serious Game to Improve Vitality, Psychological and Physical Condition, and Immune Function in Healthy Male Adults: Randomized Controlled Trial

Background

Recently, internet-based cognitive behavioral therapy (ICBT) and serious gaming interventions have been suggested to enhance accessibility to interventions and engagement in psychological interventions that aim to promote health outcomes. Few studies, however, have investigated their effectiveness in the context of simulated real-life challenges.

Objective

We aimed to examine the effectivity of a guided ICBT combined with a serious gaming intervention in improving self-reported psychophysiological and immunological health endpoints in response to psychophysiological and immune-related challenges.

Methods

Sixty-nine healthy men were randomly assigned to the intervention condition, receiving ICBT combined with serious gaming for 6 weeks, or the control condition, receiving no intervention. Self-reported vitality was the primary endpoint. Other self-reported psychophysiological and immunological endpoints were assessed following various challenges, including a bacillus Calmette-Guérin vaccination evoking pro-inflammatory responses, 1 and 4 weeks after the intervention period.

Results

Although the intervention did not affect vitality-associated parameters, self-reported sleep problems (P=.027) and bodily sensations (P=.042) were lower directly after the intervention compared with controls. Furthermore, wellbeing (P=.024) was higher in the intervention group after the psychophysiological challenges. Although no significant group differences were found for the psychophysiological and immunological endpoints, the data provided preliminary support for increased immunoglobulin antibody responses at the follow-up time points (P<.05). Differential chemokine endpoints between conditions were observed at the end of the test day.

Conclusions

The present study provides some support for improving health endpoints with an innovative ICBT intervention. Future research should replicate and further extend the present findings by consistently including challenges and a wide range of immune parameters into the study design.

Priority Symptoms, Causes, and Self-Management Strategies Reported by AYAs With Cancer

CONTEXT

Cancer and symptom experiences of adolescents and young adults (AYAs) with cancer can be highly variable, creating challenges for clinicians and researchers who seek to optimize AYAs' health outcomes. Understanding the heuristics AYAs use to designate priority symptoms can provide insight into the meaning they assign to their symptoms and self-management behaviors.

OBJECTIVES

This study described the frequency and characteristics of priority symptoms. It qualitatively explored reasons for a symptom's designation as a priority symptom, perceived causes of priority symptoms, and strategies AYAs use to manage priority symptoms.

METHODS

Participants in this single-group, longitudinal study reported symptoms using a heuristics-based symptom reporting tool, the Computerized Symptom Capture Tool, at two scheduled visits for chemotherapy. AYAs designated priority symptoms and responded to three short answer questions: What makes this a priority symptom?, What do you think causes it?, and What do you do to make it better?

RESULTS

Eighty-six AYAs, 15-29 years of age (median 19 years), identified 189 priority symptoms. Priority symptoms were of greater severity (t = 3.43; P < 0.01) and distress (t = 4.02; P < 0.01) compared with nonpriority symptoms. Lack of energy, nausea, difficulty sleeping, and pain comprised 39% of priority symptoms. Reasons for priority designation included the impact of the symptom and the attributes of the symptom. Categories of self-management strategies included "Physical Care Strategies," "Things I take (or not)," and "Psychosocial Care Strategies."

CONCLUSION

Supporting AYAs to identify their priority symptoms may facilitate a more personalized approach to care. Seeking the patient's perspective regarding priority symptoms could enhance patient-clinician collaboration in symptom management.

How to prevent, minimize, or extinguish nocebo effects in pain: a narrative review on mechanisms, predictors, and interventions

Possible factors that contribute to nocebo effects on pain are explored. Strategies that can prevent, minimize, or extinguish nocebo effects in clinical settings are suggested.

Nocebo effects, such as side effects due to negative expectations regarding the pain treatment, are a concern for health care providers and come with significant costs. This narrative review focuses on underlying mechanisms and possible factors that contribute to the susceptibility to the nocebo effect on pain and related outcomes and suggests strategies that can prevent, minimize, or extinguish nocebo effects in clinical settings. Nocebo effects are the result of psychological (eg, conditioning, verbal suggestions, and observational learning) and neurobiological (eg, cholecystokinin and dopamine regulation) mechanisms. Evidence from clinical and experimental studies lead to various recommendations and strategies to alter the nocebo effect in order to optimize pain treatments, such as providing patients with enhanced information, optimizing patient–physician communication and relationships, and offering psychoeducation on coping skills in order to manage patient expectations. The current literature from both clinical and experimental studies provides a better understanding of the nocebo effect and possible factors that modulate its strength on treatment outcomes. This allows for the development of evidence-based strategies aimed at the prevention, minimization, and treatment of the nocebo effect in pain conditions and possible other somatic disorders.

Development of the Leiden Independence Questionnaire for Support Staff: a measure of staff behaviour regarding promoting independence of people with intellectual disabilities

BACKGROUND

Support staff of adults with intellectual disability (ID) play an important role in promoting independence in home and community settings. However, little is known about the types of behaviours staff should use to promote independence and instruments that assess such behaviour do not yet exist. The aim of this study was therefore to develop and initially validate a reliable questionnaire that measures the degree to which support staff display behaviours that promote independence in people with ID.

METHOD

The Leiden Independence Questionnaire for Support Staff (LIQSS) was constructed to measure the extent to which support staff promote independence in people with ID. The LIQSS was completed by 142 staff members working with people with ID. For the psychometric evaluation of the LIQSS, a principal component analysis was performed with an oblique rotation in all items. Next, the principal component analysis was performed with a forced three-component extraction, and three sub-scales were computed. To assess internal consistency, Cronbach's α was calculated for each of the sub-scales.

RESULTS

The LIQSS was found to consist of three internally consistent (Cronbach's α was respectively 0.92, 0.79 and 0.76) and meaningful components: (1) communication, agreements and coordination; (2) positive encouragement and tailoring; and (3) supporting independent performance. The final 22 items had factor loadings between 0.44 and 0.91 on their corresponding component and a minimal difference in loading to the other factors of 0.20.

CONCLUSIONS

The LIQSS appears to be an instrument with positive face validity and reliability (internal consistency) that assesses the degree to which support staff promote independence in people with ID. To increase the instrument's value for both scientific research and clinical practice, studies should focus on the further validation of the LIQSS.

Patients' characteristics informing practice: improving individualized nursing care in the radiation oncology setting

PURPOSE

A large number of patients attend for radiotherapy daily. Primary nurses in the study settings aim to individualize care for their patients. The individual characteristics of patients may determine their perceptions of nursing care, and provide guidance in tailoring their care. This study aimed to assess patients' personal characteristics on their perceptions of individualized care (IC) provided by nurses during a course of radiotherapy, and to determine predictor variables that may inform nursing practice.

METHODS

This cross-sectional, exploratory study was conducted in three radiotherapy departments in Australia. Patients (n = 250) completed the Individualized Care Scale_Patient (ICS_P). Data were analyzed using descriptive and inferential statistics, univariate analysis, and multiple regression analysis.

RESULTS

Males reported significantly higher perceptions of IC than females in 7/9 subscales. Patients with head and neck and prostate cancer, as well as those requiring hospitalization during radiotherapy, scored significantly higher in 5/9 subscales. Courses > 30 days, those not receiving chemotherapy, and partnered patients reported greater IC across all subscales. Gender and hospitalization were the main predictor variables for IC.

CONCLUSION

Patients reported moderately high levels of IC during their radiotherapy; however, standard demographic information may provide limited insight into improving care for the individual. Patient characteristics routinely chosen, such as age, gender, and education may not predict how patients perceive their care or support the tailoring of interventions to improve IC. Researching a range of related patient characteristics may prove a more useful concept for future nursing studies aiming to predict outcomes to tailor nursing practice.

Minimizing nocebo effects by conditioning with verbal suggestion: A randomized clinical trial in healthy humans

Nocebo effects, i.e., adverse treatment effects which are induced by patients' expectations, are known to contribute to the experience of physical symptoms such as pain and itch. A better understanding of how to minimize nocebo responses might eventually contribute to enhanced treatment effects. However, little is known about how to reduce nocebo effects. In the current randomized controlled study, we tested whether nocebo effects can be minimized by positive expectation induction with respect to electrical and histaminic itch stimuli. First, negative expectations about electrical itch stimuli were induced by verbal suggestion and conditioning (part 1: induction of nocebo effect). Second, participants were randomized to either the experimental group or one of the control groups (part 2: reversing nocebo effect). In the experimental group, positive expectations were induced by conditioning with verbal suggestion. In the control groups either the negative expectation induction was continued or an extinction procedure was applied. Afterwards, a histamine application test was conducted. Positive expectation induction resulted in a significantly smaller nocebo effect in comparison with both control groups. Mean change itch NRS scores showed that the nocebo effect was even reversed, indicating a placebo effect. Comparable effects were also found for histamine application. This study is the first to demonstrate that nocebo effects can be minimized and even reversed by conditioning with verbal suggestion. The results of the current study indicate that learning via counterconditioning and verbal suggestion represents a promising strategy for diminishing nocebo responses.

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.

Tailored Therapist-Guided Internet-Based Cognitive Behavioral Treatment for Psoriasis: A Randomized Controlled Trial

OBJECTIVE

Patients with somatic conditions, such as psoriasis, frequently suffer from high burden of their disease in daily life and might benefit from internet-based cognitive behavioral therapy (ICBT) tailored to their adjustment problems. The aim of this multicenter randomized controlled trial was to examine the effects of therapist-guided, individually tailored ICBT in a clinical sample of patients with psoriasis.

METHODS

A total of 131 patients with psoriasis, who were screened for a psychological risk profile, were randomized to either care as usual (CAU, n = 66) or ICBT in addition to CAU (n = 65). Participants filled out standardized self-report questionnaires assessing physical and psychological functioning and impact on daily activities at baseline, posttreatment assessment, and 6-month follow-up.

RESULTS

In covariate-controlled linear mixed-model analyses, significantly larger improvements in ICBT compared to CAU were found in the primary outcomes physical functioning (p = 0.03, d = 0.36) and impact on daily activities (p = 0.04, d = 0.35), but not in psychological functioning (p = 0.32), up to 6 months after treatment compared to baseline. In explorative analyses, the working alliance measured at the beginning of ICBT treatment predicted improved physical (p = 0.02) and psychological (p < 0.001) outcomes.

CONCLUSIONS

Results underline the promise of therapist-guided, individually tailored ICBT to improve physical functioning and reduce the impact of psoriasis on daily activities in patients with a psychological risk profile. Establishing a good therapeutic relationship early on may be an important factor that influences treatment outcomes in personalized ICBT interventions. Further research is needed to evaluate ICBT effectiveness in additional samples and to explore its underlying mechanisms.

Use of the Psychosocial Index: A Sensitive Tool in Research and Practice

BACKGROUND

The Psychosocial Index (PSI) is a self-rating scale based on clinimetric principles that is simple to use in a busy clinical setting. It can be integrated by observer-rated clinical judgment, providing a first-line, comprehensive assessment of stress, well-being, distress, illness behavior, and quality of life. By calculation of scores, it can be used for conventional psychological measurements. Its clinical applications and clinimetric properties are reviewed. The present version of the PSI has been slightly revised. In addition, a modified version for use in adolescents and young adults (PSI-Young; PSI-Y) is also included.

METHODS

Articles that involved the use of the PSI were identified by searching the Web of Science database from 1998 to February 2016 and by a manual search of the literature.

RESULTS

A total of 20 studies reporting results from the use of PSI were included. The PSI has been employed in various clinical populations in different countries and showed high sensitivity. It significantly discriminated varying degrees of psychosocial impairment in different populations. When subjects were identified by categorical criteria (presence of allostatic overload, psychosomatic syndromes, psychiatric disorders), the PSI scores were significantly different across subgroups.

CONCLUSIONS

In clinical practice, scanning the list of symptoms allows clinicians to assess rapidly which symptoms and problems are perceived as most troublesome. In research settings, the use of scores makes the PSI a valid and sensitive tool in differentiating levels of psychosocial variables among groups.

The role of psychological factors in inflammatory rheumatic diseases: From burden to tailored treatment

Inflammatory rheumatic diseases have a long-lasting effect on patients' physical and psychological functioning, for instance, due to disabling symptoms and unpredictable disease course. Consequently, many patients show adjustment problems such as depressed mood, which in turn can negatively influence their disease outcome. Specific biopsychosocial factors have shown to affect this outcome. For example, daily stress, cognitive-behavioral risk factors such as pain catastrophizing and avoidance, and resilience factors such as optimism and social support influence the quality of life, physical symptoms of pain and fatigue, and inflammatory markers. Psychological interventions tackling these factors can have beneficial effects on physical and psychological functioning. Recent advances in screening for patients at risk, tailored treatment, and eHealth further broaden the efficiency and scope of these interventions while simultaneously optimizing patient empowerment. This chapter describes the biopsychosocial risk and resilience factors related to disease outcome and the possible benefits of psychological treatment strategies in inflammatory rheumatic diseases.

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.

The role of outcome expectancies for a training program consisting of meditation, breathing exercises, and cold exposure on the response to endotoxin administration: a proof-of-principle study

Expectancies play a major role for the treatment outcome of a broad variety of immune-mediated conditions and may strengthen or mimic the effects of regular long-term therapies. This study adds to a recently published study of Kox et al. (PNAS 111:7379-7384, 2014) on the ability to voluntarily influence the physiological stress response in healthy men after a training program consisting of meditation, breathing techniques, and exposure to cold, which found highly promising results on the clinical, autonomic, and immune response to experimentally induced inflammation (using the experimental human endotoxemia model). Within this project, a number of variables were included to assess the role of generalized (optimism, neuroticism) and specific outcome expectancies (related to the effects of the training on health) on the response to endotoxin administration after training. Indications were found that especially the generalized outcome expectancy optimism is a potential determinant of the autonomic (epinephrine: rho = 0.76, p < .01) and immune response (interleukin-10: rho = 0.60, p < .05) to induced inflammation after training, whereas more specific expectations with regard to the effects of the training could be especially relevant for the clinical symptom report (flu-like symptoms: rho = -0.71, p < .01). This proof-of-principle study provides first indications for potential innovative treatments to change immune-modulating responses by means of psychological mechanisms. If replicated, these findings may be used for predicting training responses and potentiate their effects by means of optimism-inducing interventions in patients with immune-mediated rheumatic conditions.
