Examining illness perceptions over time: an exploratory prospective analysis of causal attributions in individuals with depressive symptoms

BACKGROUND

According to the Common-Sense Model of Illness Representations, illness beliefs, such as causal attributions, can influence the way people assess and cope with their illness and vice versa. To date, causal attributions in people with depressive symptoms have been studied mainly cross-sectionally, quantitatively and independently. The purpose of this study is to examine the causal attributions of people with depressive symptoms in terms of their stability over time, dependence on treatment experience, and differentiation of causal concepts.

METHODS

In a population-based prospective sample, people with at least mild depressive symptoms (PHQ-9 Score ≥ 5) were interviewed via telephone at T0 and twelve months later (T1). Causal attributions were assessed using the Brief Illness Perception Questionnaire. After the open responses were qualitatively analysed using a deductive-inductive approach, stability over time was assessed for causal attributions and concepts by comparing answers between the two time points. Subsequent exploratory quantitative analyses were conducted using chi-square tests, t-tests, and logistic regression analyses.

RESULTS

A total of 471 individuals (age M = 53.9, 53.6% female) with a mean PHQ-9 Score of 8.4 were included in the analyses. Causal attributions related to participants' social environment, workplace, and past are the most stable over time. However, individuals with and without a time-stable causal concept showed no differences in terms of sociodemographic characteristics, severity of depressive symptoms, risk of comorbidity, and treatment experiences. Overall, the causal concepts of people with depressive symptoms appear to be very diverse. Those with treatment experience (M = 2.21, SD = 0.80) named significantly more causal attributions compared to people without treatment experience (M = 1.98, SD = 0.81, t(471) = -3.060, p < 0.01). In addition, logistic regression analyses revealed that treatment-experienced respondents were more likely to attribute "childhood/youth/parental home" and "predisposition".

CONCLUSIONS

Our study reveals that people with treatment experience tend to report treatment-congruent causal attributions, such as childhood and family environment, as well as predisposition, more frequently. Understanding how causal attributions and concepts are formed and change can be helpful for addressing causal attributions in treatment. Future studies should take into account the benefits of employing qualitative survey methods for exploring causal attributions.

Illness perception in functional neurological disorder: low illness coherence and personal control

Introduction

Illness perception refers to patients' subjective representations and appraisals of somatic and mental symptoms. These are relevant for self-management and outcome. In clinical practice, patients with functional neurological disorder (FND) often encounter a fragmented biomedical attitude, which leaves them without clear concepts. In this context, illness perception is relevant.

Methods

Illness perception was assessed in FND patients and compared with samples of psychosomatic patients (PSM) as well as poststroke patients (STR). The three samples (FND, n=87; PSM, n=97 and STR, n=92) were almost all in inpatient treatment or rehabilitation. Illness perception was assessed with the revised German version of the Illness Perception Questionnaire (IPQ-R). For assessments of correlations, depressive symptoms were tested with the Patient Health Questionnaire-9, dissociative and functional neurological symptoms by the German adaption of the Dissociative Experiences Scale and biopsychosocial complexity by the INTERMED Self-Assessment questionnaire.

Results

Apart from the chronicity subscale, all dimensions of the IPQ-R differed between groups. FND patients perceived lower illness coherence and personal control than both other groups and attributed their illness more to chance than to behavioural risk factors. PSM patients had the strongest emotional representations. There were only few correlations with dissociative scores and biopsychosocial complexity.

Conclusion

Illness perception is an important issue in patients with FND with particular emphasis on low illness coherence and personal control. Missing associations with biopsychosocial complexity suggest that subjective illness perception is an important complementary but separate issue, which likely influences therapeutic alliance and self-management in FND. Future studies should assess its influences on outcome.

The association of early response with the outcome of psychosomatic rehabilitation in patients with mental disorders and its link to treatment and illness beliefs-A prospective longitudinal cohort study

Early response is considered to be an important predictor for therapy outcomes; yet little is known about its relevance in psychosomatic rehabilitation. This paper aims to describe the association of early response in psychosomatic rehabilitation, as well as the associations of early response with pre-rehabilitative factors such as illness and treatment beliefs.

A longitudinal study with three measurement points was applied. Early response was defined using the percent improvement method after two weeks of treatment. Its association with therapy outcome and with illness and treatment beliefs was analyzed using multiple regression analyses.

A total of 264 participants took part. Early response was a significant predictor of psychosomatic rehabilitation outcome, explaining an incremental variance of 1-30% after controlling for initial symptom burden. Illness and treatment beliefs predicted 6-20% variance in early response. Important illness beliefs referred to perceived symptoms, consequences and comprehensibility of the illness. Important treatment beliefs referred to expectations about rehabilitation structure, processes and concerns.

Early response is associated with the therapy outcome of psychosomatic rehabilitation, with illness and treatment beliefs found to be associated with early response. Further research on the predictors of early response in psychosomatic rehabilitation is needed.

The puppet interview to measure illness perceptions in paediatric oncology: development and psychometric properties in acute treatment and follow-up care

BACKGROUND

Illness perceptions comprise assumptions about symptoms, timeline, consequences, controllability, and emotional responses to an illness. Recent evidence shows that illness perceptions are associated with coping and well-being. So far, assessment in paediatric care was based on parental report only, since no instrument for the direct assessment of young children was available. We aim to describe the development (incl. indication and contraindication) of an innovative puppet interview to assess illness perceptions in children with cancer from the age of four years. Moreover, we investigate longitudinal trajectories and examine psychometric properties.

METHODS

The puppet interview was developed based on the Illness-Perception-Questionnaire-Revised and the Berkeley-Puppet-Interview. Longitudinal trajectories and psychometric properties were examined in a sample of patient-parent dyads (N = 75) in a prospective longitudinal study in acute treatment with a 1-year follow-up (study 1: nT1 = 41, nT2 = 27) and in a cross-sectional study in follow-up care (study 2, n = 34).

RESULTS

The puppet interview is comprehensible and well-received by children in acute treatment and follow-up care. There were significant differences in perceptions of a chronic timeline (U = 301.00, p = .008), consequences (U = 251.00, p = .008), and emotional representations (U = 244.50, p = .020) between children in acute treatment and children in follow-up care. Over the course of one year, children in acute treatment perceived more symptoms as part of their illness (MT1 = 3.6, SDT1 = 2.9, MT2 = 4.5, SDT2 = 3.1, n = 27, Z = -2.603, p = .009). We found expected intercorrelations between illness perception dimensions, e.g. between perception of consequences and emotional representations (rτ = .27, p = .033), and between perception of a chronic timeline and consequences (rτ = .38, p = .001). Moreover, we found confirming results regarding construct validity, as child's perceptions of symptoms correlated with their self-rated HRQoL (rτ = -.32, padj. = .014). Also parent-rated subscale on illness-specific aspects of child's HRQoL correlated with child's perception of symptoms (rτ = -.26, padj. = .016), cyclicity (rτ = -.28, padj. = .016), and consequences (rτ = -.34, padj. = .014). Acceptable internal consistency was shown for the dimensions timeline-acute/chronic and personal control.

CONCLUSIONS

Parental report can now be complemented by a self-report of illness perceptions in children aged four years and older. This will allow for the further adaptation of medical and psychosocial care during and after acute cancer treatment.

Psychometric properties of the rehabilitation treatment beliefs questionnaire for psychosomatic rehabilitation

PURPOSE

Treatment beliefs play a crucial role for patient satisfaction and the treatment outcome in psychosomatic rehabilitation. The aim of this study was the development and the psychometric evaluation of an indication-specific questionnaire of beliefs about psychosomatic rehabilitation.

MATERIALS AND METHODS

The study was conducted at a psychosomatic rehabilitation clinic. The primary item list comprised k = 125 items. After a descriptive item analysis, we conducted an exploratory factor analysis. Furthermore, we tested reliability via McDonald's Omega and construct validity by analyzing correlations of the scales with related constructs.

RESULTS

Of the N = 264 participants, 50% were female and the mean age was 50.4 (SD = 9.8) years. K = 85 items were suitable for factor analysis, which resulted in k = 30 items constituting six scales, explaining of 57% the overall variance. The corrected item-total correlations were between r = 0.48 and r = 0.83. Internal consistency ranged from ω = 0.81 to ω = 0.86.

CONCLUSION

The newly developed questionnaire assesses specific treatment beliefs about inpatient psychosomatic rehabilitation. The psychometric properties of the six scales are acceptable. Further studies should confirm the psychometric results, such as the factorial structure of the questionnaire.IMPLICATIONS FOR REHABILITATIONTreatment beliefs are known to play an important role for the adherence, therapy outcome and satisfaction in psychosomatic rehabilitation.We developed and tested a indication-specific questionnaire assessing treatment beliefs in psychosomatic rehabilitation.The questionnaire can be used to explore patient's rehabilitation-related treatment beliefs, predict treatment outcomes, and to develop interventions attempting to modify these.

Illness Perceptions of Patients with Occupational Skin Diseases in a Healthcare Centre for Tertiary Prevention: A Cross-Sectional Study

Objectives: To investigate the illness perceptions of patients with occupational skin diseases (OSDs). Design: Cross-sectional study. Setting: Specialised healthcare centre for inpatient and outpatient individual prevention in occupational dermatology in Germany. Participants: A total of 248 patients with hand eczema (55.2% female; average age: 48.5 years, SD: 11.9) were included in the final analyses. Measures: A modified and recently validated version of the 'Revised Illness Perception Questionnaire' (IPQ-R) was used to assess illness perceptions. Severity of skin disease was evaluated with the Patient-Oriented Eczema Measure (POEM), the Osnabrueck Hand Eczema Severity Index (OHSI), and a single, self-reported global item. The Erlangen Atopy Score (EAS) was used for atopy screening. Results: We found strong illness identity, high emotional impact, and long timeline beliefs, meaning that study participants perceive their OSD on the hands as a highly symptomatic, emotionally burdening, and chronic condition. Results suggest that hand eczema has a major impact on how participants manage their own lives, particularly during everyday life and occupational activities. Study participants predominantly identified irritant or sensitising substances and activities at work as well as skin protection regimes as causes of their disease. Conclusions: Healthcare workers should consider the illness perceptions as well as the disease burden of patients with an OSD on the hands in clinical practice. Multi-professional approaches to patient care should be sought. Illness perception in (occupational) dermatological patients should be the subject of further research.

Illness Beliefs, Treatment Beliefs, and Fulfilled Treatment Expectations in Psychosomatic Rehabilitation: Associations with Patient Satisfaction

Purpose

Patients' illness and treatment beliefs have been shown to predict health outcomes in many health care settings. However, information about their impact on patient satisfaction is scarce. The aim of this study was to investigate illness- and rehabilitation-related treatment beliefs and met rehabilitation-related treatment expectations and their relationship with patient satisfaction in psychosomatic rehabilitation.

Methods

In a repeated measures study design, patients filled out questionnaires 2 to 3 weeks before the start of rehabilitation and at the end of an inpatient rehabilitation 6 to 7 weeks later. The predictive value of illness beliefs, treatment beliefs, and fulfilled treatment expectations regarding patient satisfaction was analyzed with multiple hierarchical regression analyses controlling for sociodemographic and clinical variables.

Results

Two hundred sixty-four patients participated. The sample was composed of equal numbers of men and women (n = 129 each). The mean age was 50.4 years. Most patients had diagnoses from the ICD-10 diagnostic group F3 (affective disorders; n = 145) or F4 (neurotic, stress-related and somatoform disorders; n = 94). Sociodemographic and clinical variables were not associated with patient satisfaction. The explained variance of patient satisfaction increased to 10% by adding illness beliefs (namely personal control and coherence) (p = 0.006), to 5% by adding rehabilitation-related treatment beliefs (namely concerns) (p = 0.063), and to 49% by adding fulfilled expectations (namely a positive discrepancy between expectations and experiences related to outcome expectations and related to participation and treatment structure, and a negative discrepancy between expectations and experiences related to concerns) (p < 0.001) as predictor variables.

Conclusion

This study highlights the relationship of fulfilled (rehabilitation-related) treatment expectations with patient satisfaction in psychosomatic rehabilitation. Given the evidence underlining the importance of patients' illness and treatment beliefs and expectations, it is vital that these constructs are addressed in corresponding interventions.

What Causes Cancer in Women with a gBRCA Pathogenic Variant? Counselees' Causal Attributions and Associations with Perceived Control

Laypersons have a strong need to explain critical life events, such as the development of an illness. Expert explanations do not always match the beliefs of patients. We therefore assessed causal attributions made by women with a pathogenic germline variant in BRCA1/2 (gBRCA1/2-PV), both with and without a cancer diagnosis. We assumed that attributions would be associated with the control experience. We conducted a cross-sectional study of N = 101 women with a gBRCA1/2-PV (mean age 43.3 ± 10.9). Women answered self-report questionnaires on perceived causes and control. Most women (97%) named genes as a causal factor for the development of cancer. Surprisingly, the majority of women also named stress and health behavior (both 81%), environment (80%), and personality (61%). Women with a cancer diagnosis tended to endorse more causes. The attributions to personality (ρ = 0.39, p < 0.01) health behavior (ρ = 0.44, p < 0.01), and environment (ρ = 0.22, p < 0.05) were significantly associated with personal control, whereas attribution to genes showed a small, albeit significant association with treatment control (ρ = 0.20, p < 0.05). Discussing causal beliefs in clinical counseling may provide a “window of opportunity” in which risk factors and health behaviors could be better addressed and individually targeted.

Kontextfaktoren der patient*innenseitigen Selbstregulation in der psychosomatischen Rehabilitation – eine Querschnittsanalyse vor Rehabilitationsbeginn

BACKGROUND

Contextual factors are a central element of the ICF and important factors for therapy planning in psychosomatic rehabilitation. At the same time, little is known about the relationship between contextual factors and patient self-regulation, an important goal of rehabilitation.The aim of this study is therefore to investigate the relationship between contextual factors and illness belies. Illness beliefs are a core element of self-regulation in psychosomatic rehabilitation and part of the common sense model of self-regulation.

METHODS

Between April 2019 and January 2020, a cross-sectional questionnaire study was conducted in a psychosomatic rehabilitation clinic, in which registered rehabilitation patients were questioned about their illness beliefs using the Illness Perception Questionnaire (IPQ-R). Contextual factors were divided into clinically modifiable and non-clinically modifiable and included gender, age, duration of illness, subjective social status, main diagnosis (dichotomised: F3/F4), occupational stress, depressive stress as well as activity and participation (operationalised by the Health-49). Multiple regressions were used for the analysis, in which the scales of the IPQ-R served as dependent variables.

RESULTS

N=264 rehabilitants took part in the survey, 50% of them were female. The average age was 50 years. With regard to the non-clinically modifiable contextual factors, it was shown that a younger age was associated with higher control assumptions, but that younger rehabilitation patients simultaneously perceived more symptoms due to their illness (identity). A longer duration of illness showed a connection with the chronic timeline assumptions. A lower social status showed correlations with lower control assumptions and more assumptions about the cyclical timeline. Regarding clinically modifiable contextual factors, an F3 diagnosis was associated with more expected consequence, but also with a higher perceived personal control than an F4 diagnosis. A higher occupational burden was associated with the assumption of a more chronic course of the disease. Reduced activity and participation were associated with more expected consequences and more perceived symptoms (identity). Depressive stress showed associations with six out of eight domains of illness beliefs.

CONCLUSION

The study supports the relevance of contextual factors, which in majority can be discussed as person-related factors, for patient self-regulation in psychosomatic rehabilitation. Interventions to increase self-regulation, e. g. by taking illness beliefs into account, have already achieved promising results, also in the context of rehabilitation. The patient-oriented approach of these interventions could be further strengthened by a stronger inclusion of contextual factors.

Swiss chiropractic practice-based research network and musculoskeletal pain cohort pilot study: protocol of a nationwide resource to advance musculoskeletal health services research

INTRODUCTION

Musculoskeletal (MSK) pain conditions, a leading cause of global disability, are usually first managed in primary care settings such as medical, physiotherapy, and chiropractic community-based practices. While chiropractors often treat MSK conditions, there is limited real-world evidence on the topic of health service outcomes among patients receiving this type of care. A nationwide Swiss chiropractic practice-based research network (PBRN) and MSK pain patient cohort study will have potential to monitor the epidemiological trends of MSK pain conditions and contribute to healthcare quality improvement. The primary aims of this protocol are to (1) describe the development of an MSK-focused PBRN within the Swiss chiropractic setting, and (2) describe the methodology of the first nested study to be conducted within the PBRN-an observational prospective patient cohort pilot study.

METHODS AND ANALYSIS

This initiative is conceptualised with two distinct phases. Phase I focuses on the development of the Swiss chiropractic PBRN, and will use a cross-sectional design to collect information from chiropractic clinicians nationwide. Phase II will recruit consecutive patients aged 18 years or older with MSK pain from community-based chiropractic practices participating in the PBRN into a prospective chiropractic cohort pilot study. All data collection will occur through electronic surveys offered in the three Swiss official languages (German, French, Italian) and English. Surveys will be provided to patients prior to their initial consultation in clinics, 1 hour after initial consultation, and at 2, 6 and 12 weeks after initial consultation.

ETHICS AND DISSEMINATION

Ethics approval has been obtained from the independent research ethics committee of Canton Zurich (BASEC-Nr: 2021-01479). Informed consent will be obtained electronically from all participants. Findings will be reported to stakeholders after each study phase, presented at local and international conferences, and disseminated through peer-reviewed publications.

Beliefs About Causes and Cures of Prolonged Grief Disorder Among Arab and Sub-Saharan African Refugees

Background

Many refugees have experienced the death of a loved one under traumatic circumstances. Accordingly, the prevalence of Prolonged Grief Disorder (PGD) among refugees is high. Culture-specific symptoms of PGD have been described previously, but beliefs about causes and cures of PGD among refugees remain unknown. We therefore aimed at identifying illness beliefs and treatment expectations regarding PGD among refugees.

Method

We focused on refugees from Arab countries (n = 14) and from Sub-Sahara Africa (n = 9) and applied qualitative and quantitative methods. In a semi-structured interview, participants first answered questions about assumed causes and potential cures for prototypical PGD symptoms according to ICD-11 that were presented in a vignette as representatives of their own culture. In the quantitative part, they completed the Cause Subscale of the Illness Perception Questionnaire (IPQ-R) that included additional culture-specific items. Interviews were analyzed with Qualitative Content Analysis.

Results

In both groups of refugees, PGD symptoms were predominantly attributed to a close relationship to the deceased, lack of social support, personal vulnerabilities, and circumstances of the death. Participants also named a number of flight-related causes (e.g., inability to perform or participate in rituals, feeling isolated in the host country). None of the participants attributed PGD symptoms to supernatural causes. Descriptive analyses of responses on the IPQ-R indicated that participants predominantly attributed PGD symptoms to psychological causes. Participants believed that PGD can be cured and predominantly mentioned social and religious support. Psychological help was only mentioned by a minority of participants. In both groups, participants emphasized that a therapist must be familiar with the patient's culture and rituals. Participants also mentioned stigma associated with seeking psychological help.

Conclusion

Results suggest specific beliefs of refugees regarding causes and cures of PGD as well as similarities with Western conceptualizations. A culture-sensitive approach to the treatment of PGD in refugees that can include knowledge of culture-specific rituals and incorporating religious beliefs as well as decreasing stigma and increasing mental health literacy seem important. The study is limited by its focus on only two groups of refugees and its small sample size.

The impact of illness perception on functionality, pain, stiffness, and activity of daily living after total hip replacement surgery

OBJECTIVE

According to the Common Sense Model (CSM), cognitive and emotional representations influence recovery. We used groups of individuals grouping multiple cognitive representations (schemas) to predict the recovery process after total hip arthroplasty (THR).

METHODS

The aim of this prospective cohort study with three collection time points was to examine the significance of these schemas for functionality three and six months after THR. We assessed illness perception with the Illness Perception Questionnaire-Revised and the functionality with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Data were collected four weeks before (n = 317), three (n = 268), and six months after (n = 292) primary THR. Groups of individuals with the same schemas were identified using a two-step cluster analysis across cognitive representations. Controlling for WOMAC variables (functionality, stiffness, pain, and activities of daily living) before THR, we calculated the regression of schemas and emotional representations before THR on WOMAC variables after THR.

RESULTS

Before THR, two cognitive schemes were found: Schema One: medium identity, long duration, many consequences, low personal and treatment control, and low coherence; Schema Two: low identity, short timeline, low consequences, and high personal and treatment control. Patients with Schema Two had better functionality and lower pain and stiffness three months after surgery compared to those with Schema One. After three months, the influence of cognitive schemas was stronger on functionality than that of emotional representation (f²: 0.04 /0.02).

CONCLUSION

Further study is needed to determine whether a psychological intervention can change Schema One.

Illness and treatment beliefs as predictors of rehabilitation outcome in patients with mental disorders

OBJECTIVE

Illness and treatment beliefs are important predictors of health outcomes. However, little is known about their impact on outcomes in psychosomatic rehabilitation. Thus, the aim of this study was to investigate the impact of illness and rehabilitation-related treatment beliefs in patients with mental disorders attending psychosomatic rehabilitation.

METHODS

We applied a longitudinal study with two measurement points (before rehabilitation; end of rehabilitation) in a psychosomatic rehabilitation clinic. Patients with mood disorders, anxiety or fear-related disorders, stress associated disorders or bodily distress disorders were included. Using regression models, we analysed whether illness and rehabilitation-related treatment beliefs predicted the rehabilitation outcome (operationalised through "Health-49"). Illness beliefs were assessed using the IPQ-R, while treatment beliefs were assessed using the RTBQ-Psych. Analyses were conducted separately for patients with a F3 and F4 diagnosis in accordance with the ICD-10.

RESULTS

N = 239 patients were included, sample size per regression model ranged between n = 48 and n = 85. Mean age was 50.8 years, and n = 120 were female. Initial symptom burden was the strongest predictor in all models with 12% to 64% explained variance. Concerning illness beliefs, perceived consequences, treatment control, and cyclic timeline were negatively linked to the outcome, whereas coherence and emotional representations were shown to be positive predictors. Regarding treatment beliefs, expectations towards treatment results were positively and concerns were negatively associated predictors.

CONCLUSION

Illness and treatment beliefs are predictors of the rehabilitation outcome. Patients´ beliefs might therefore be good starting points for interventions in the context of rehabilitation.

Gender and Emotional Representation Matter: Own Illness Beliefs and Their Relationship to Obesity

Background

Current treatments of obesity often fail to consider gender and psychological aspects, which are essential for weight loss and weight maintenance. The aim of our study was to analyze subjective illness representations (SIRs) of adults with obesity according to the Common-Sense Self-Regulation Model (CSM) by assessing their associations with weight-related variables and gender.

Methods

Data was collected via online self-assessment between April 2017 and March 2018. SIRs were operationalized by the revised Illness Perception Questionnaire (IPQ-R) and illness outcomes according to the CSM were defined as BMI, eating behaviour, physical wellbeing, bodyweight satisfaction, and shape concerns. The sample consisted of 427 adults (M = 42.2 years, SD = 10.9; 82% female) with obesity (BMI: M = 42.3 kg/m², SD = 9.0). Student's t-tests and multiple hierarchical regression analyses were conducted with the control variables (age and BMI) and subjective illness representations and gender as independent variables.

Results

The explanation of outcome variances was moderate to high (21-43%) except for restraint eating behaviour (10%). Subjective illness representations showed several significant associations with weight-related variables, especially timeline and emotional representations. Female gender was significantly associated with more restraint eating behaviour [F_{(1, 400)} = 4.19, p < 0.001] and females had unfavourable values of the weight-related variables as well as a more cyclic [t₍₄₂₅₎ = 3.68, p < 0.001], and more emotional representation [t₍₁₀₀₎ = 5.17, p < 0.001] of their obesity.

Conclusion

The results of this study indicate that gender and subjective illness representations, especially the emotional representation, play an important role for weight-related variables. Therefore, the assessment of SIRs may constitute an economic tool to identify specific individual deficits of self-regulation.

Late Presentation at Primary Diagnosis of Breast Cancer: Patients' Personality Characteristics and Attitudes

Introduction

Breast cancer (BC) is the most common cancer in women worldwide. Despite screening and information efforts, about 10% of patients present with tumor size T3 or T4 at primary diagnosis. Late presentation is associated with more advanced tumor stage and consecutively with worse survival rates.

Objective

This study aimed to evaluate whether patients with a late presentation at primary BC diagnosis differ in their personality from those with early diagnosis.

Methods

In this bicentric, observational study, personality traits, positive and negative affectivity, anxiety, spirituality, illness beliefs, and sociodemographic characteristics were assessed in BC patients who presented with T-stages 3 or 4 (late presenters) and T-stages 1 or 2 (controls) at initial diagnosis.

Results

Forty patients (20 controls, 20 late presenters) were interviewed. "Late presenters" perceived their disease as long lasting and had significantly more "positive affectivity" in the current trait. Although no significant associations were found, there was a trend for late presenters to have higher education levels, less spiritual longing, less accurate explanation of their illness, less anxiety in the trait scale, and more conscientiousness than the controls.

Conclusion

As patients with late presentation for BC differ in specific psychological and sociodemographic characteristics from patients with early BC, the findings of this pilot project warrant additional investigations to identify further specific characteristics and motivations. Identifying patients at risk for late presentation and encouraging them to accept an earlier diagnosis could help to improve their therapy and, finally, their outcome.

Does Weight-Cycling Influence Illness Beliefs in Obesity? A Gender-Sensitive Approach

Obesity is classified as a chronic disease. Women and men seem to face different obstacles in their attempts to overcome one of the most challenging tasks in the treatment of this disease, namely, weight reduction maintenance. The Common-Sense-Model (CSM) is mainly used to improve the understanding of self-regulation and health behaviour in chronic diseases but has yet to be explored for obesity. This paper applies the CSM to obesity, focussing on the construct of illness representations, which is the basis of health behaviour according to the CSM. A sample of n = 356 women and n = 77 men with obesity was investigated to assess the extent that illness representations in obesity are shaped by experiences of weight-cycling and the extent that gender influences their quality. Our results show that the representations of timeline and consequences as well as the emotional representation are particularly influenced by weight-cycling, especially in men. On average, women showed more maladaptive illness representations than men. These findings not only contribute to a better applicability of the CSM in obesity, but also emphasize the importance of gender in obesity research and interventions.

Efficacy of a Brief, Peer-Delivered Self-management Intervention for Patients With Rare Chronic Diseases: A Randomized Clinical Trial

IMPORTANCE

Patients coping with rare diseases need psychosocial support.

OBJECTIVE

To evaluate the efficacy of a brief, transdiagnostic, peer-delivered intervention for patients with rare diseases in addition to care as usual (CAU) compared with CAU only.

DESIGN, SETTING, AND PARTICIPANTS

In this 2-group randomized clinical trial conducted from October 5, 2017, to July 12, 2019, patients were recruited via specialized clinics and patient organizations across Germany and participated from home. The study included consecutive adult patients with neurofibromatosis type 1, Marfan syndrome, primary sclerosing cholangitis, and pulmonary arterial hypertension who have limited functionality because of the disease. Exclusion criteria were a life-threatening health status and ongoing psychotherapeutic treatment. Of 143 patients screened for eligibility with a semistructured telephone interview, 54 were excluded, and 89 were randomized: 45 patients were randomly allocated to the peer-delivered intervention group, and 44 to the control group; 87 patients (98%) completed the 6-month follow-up assessment. The analysis was performed using an intention-to-treat principle. Data cleansing and analysis were conducted between April 25, 2019, and February 13, 2020.

INTERVENTIONS

The 6-week intervention consisted of a self-help book and telephone-based peer counseling in addition to CAU. The control group received CAU alone. Peer counselors received training, structured consultation guidelines, and supervision.

MAIN OUTCOMES AND MEASURES

The primary outcome was acceptance of the disease as assessed using the Illness Cognition Questionnaire (ICQ; mean sum scores range from 0 to 18, with higher values representing more acceptance) 6 months after the intervention. Secondary outcomes included self-reported coping strategies (Health Education Impact Questionnaire), illness cognition (ICQ and Illness Perception Questionnaire), depression severity (Patient Health Questionnaire 9-item depression scale), anxiety severity (Generalized Anxiety Disorder Scale), quality of life (12-Item Short-Form Health Survey), and social support (Social Support Questionnaire). Outcomes were assessed before the intervention, after the intervention, and at a 6-month follow-up.

RESULTS

The mean (SD) age of the 89 participating patients was 46.3 (14.9) years; 59 (66%) were women. There were no group differences regarding baseline variables. All patients allocated to the intervention group completed the intervention. Six months after the intervention, but not directly after completing the program, the intervention group had significantly higher rates of acceptance (ICQ) of the disease (primary outcome) compared with the CAU group. Mean (SD) baseline ICQ scores were 9.61 (3.79) in the control group and 9.86 (3.40) in the intervention group. Mean (SE) ICQ scores at 6 months were 10.32 (0.42) for the control group and 11.79 (0.42) for the intervention group, with a significant mean difference of -1.47 (95% CI, -2.63 to -0.31; P = .01). Several secondary outcomes, including different coping strategies, social support, and mental quality of life, were significantly higher after the intervention compared with the control group.

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial, a self-help and peer counseling intervention improved patients' acceptance of their rare chronic diseases. Self-management and peer support can efficiently address the unique care needs of patients with rare diseases.

Making Sense of a Health Threat: Illness Representations, Coping, and Psychological Distress among BRCA1/2 Mutation Carriers

Little is known about how women with a BRCA1/2 mutation develop an individual understanding of their breast and ovarian cancer risk and how this affects their psychological distress. In this study, we investigated associations between illness representations, coping strategies and psychological distress. N = 101 BRCA1/2 mutation carriers answered self-report questionnaires on illness representations, coping strategies, cancer worry and depressive symptoms. Women without cancer were compared to women with a previous cancer diagnosis. Illness representations explained 50% and 45% of the variability in cancer worry and depressive symptoms, respectively. Woman perceiving severe consequences (β = 0.29, p < 0.01) and having more concerns (β = 0.37, p < 0.01) were found to report more cancer worry. Perceiving information about the mutation as less coherent (β = −0.17, p < 0.05) and experiencing negative emotional responses (β = 0.60, p < 0.01) were both associated with more depressive symptoms. Women with a previous cancer diagnosis show patterns of illness representations that are potentially more distressing than women without a cancer diagnosis. Findings suggest that physicians involved in counseling should pay attention to illness representations of distressed women. Thereby, it would be possible to detect maladaptive thoughts associated with the mutation, address negative emotions and encourage adaptive coping strategies.

Influence of established and subjectively perceived as well as evaluated individual characteristics on the utilization of mental health services among individuals with depressive disorders: protocol of a longitudinal study examining how to supplement the "behavioral model of health services use" and on need-congruent use of mental health services

BACKGROUND

Approximately one out of every three people in Germany who meets the diagnostic criteria for major depression has contact with mental health services. Therefore, according to treatment guidelines, two thirds of all individuals with depression are insufficiently treated. In the past, the subjective perspective of people who (do not) make use of mental health services has been neglected. Factors related to the use of health services are described in Andersen's Behavioral Model of Health Services Use (ABM). The aim of this study is to supplement operationalizations of subjectively perceived and evaluated individual characteristics in the ABM and to evaluate whether the supplemented model can better explain mental health services use in individuals with depression than established operationalizations.

METHODS

A representative telephone study with two measurement points will be conducted. In an explanatory mixed-methods design, qualitative interviews will be added to further interpret the quantitative data. A nationwide sample scoring 5 or more on the Patient Health Questionnaire (PHQ-9) will be recruited and interviewed via telephone at T0 and 12 months later (T1). Data on established and subjective characteristics as well as mental health service use will be collected. At T1, conducting a diagnostic interview (Composite International Diagnostic Interview, DIA-X-12/M-CIDI) enables the recording of 12-month diagnoses according to DSM-IV-TR criteria. Ideally, n = 768 datasets will be available and analyzed descriptively by means of regression analysis. Up to n = 32 persons who use or do not use depression-specific health services incongruent with their objective or subjective needs will be interviewed (face-to-face) to better explain their behavior. In addition, theories of non-need-based mental health service use are developed within the framework of the grounded theory-based analysis of the qualitative interviews.

DISCUSSION

The study intends to contribute to the theoretical foundation of health services research and to specify the characteristics described in the ABM. Thus, after completion of the study, a further sophisticated and empirically tested model will be available to explain mental health services. The identified modifiable influencing factors are relevant for the development of strategies to increase mental health service use in line with the objective and subjective needs of individuals with depression.

A cross-sectional study on self-reported physical and mental health-related quality of life in rheumatoid arthritis and the role of illness perception

BACKGROUND

Psychosocial models including illness perception might explain individual differences in health-related quality of life (HRQoL) and daily functioning in chronically ill patients. The aim of this study was to assess the association of illness perception among rheumatoid arthritis (RA) patients with physical and mental HRQoL, adjusted for demographic variables, clinical variables and social support.

METHODS

A cross-sectional study conducted at a Viennese rheumatology outpatient clinic on 120 RA patients. Participants completed questionnaires on demographic and clinical characteristics, HRQoL (SF-36 Questionnaire), illness beliefs (Brief Illness Perception Questionnaire) and social support (Social Support Scale-8). Analyses were performed with multivariate linear regression.

RESULTS

The mean physical was lower (38.38) than the mean mental SF-36 summary score (46.94). In univariate analysis, all domains of illness perception except belief in a chronic disease course were associated with physical and mental HRQoL. In multivariate analyses, illness perception accounted for 51% of variance in physical HRQoL. A stronger belief in the consequences of RA (consequences, β = - 0.33) and a stronger belief in repeated disease recurrence (timeline cyclical, β = - 0 .31) were significantly associated with physical HRQoL in the fully adjusted model. Illness perception accounted for 45% of variance in mental HRQoL. Emotional representation (β = - 0 .27) and fatigue (β = - 0 .36) were significantly associated with mental HRQoL in the fully adjusted model.

CONCLUSION

This study highlights the importance of RA patients' beliefs about their illness and symptoms in relation to HRQoL. Identification of patients' perception of RA may be a way to positively influence disease outcomes such as quality of life as illness perception is amenable to intervention.

Illness representations, pain and physical function in patients with rheumatic disorders: between- and within-person associations

OBJECTIVES

Rehabilitation for patients with rheumatic diseases improves both illness representations (IR) and clinical outcomes such as pain and physical functioning (PF). However, it is unclear whether IR may affect and, in turn, are affected by pain and PF. In this study, we examined both between-person associations and within-person associations between IR and pain/PF over time on three measurement occasions. Furthermore, cross-lagged relationships were examined.

DESIGN AND MAIN OUTCOME MEASURES

This secondary analysis is based on data from N = 186 patients with rheumatic diseases. Data on pain, PF and IR were assessed using self-report questionnaires at the beginning, the end and three months after a 3-week inpatient rehabilitation.

METHODS

To separate between- and within-person level, data were analysed using random-intercept cross-lagged panel models.

RESULTS

On both the between-person level (r = |0.21| - |0.44|) and the within-person level (r = |0.15| - |0.46|), pain and PF were related to cognitive and emotional IR. In addition, we found within-person bidirectional cross-lagged effects between emotional IR and PF.

CONCLUSION

IR show complex relationships with pain and PF. Improving PF might improve subsequent illness-related emotional distress and vice versa.

Illness Beliefs, Treatment Beliefs and Information Needs as Starting Points for Patient Information: The Evaluation of an Intervention for Patients with Depression

Patients with depression are often dissatisfied with disease- and therapy-related information. The objective of this study was to evaluate an intervention that applied the Common Sense Model to the provision of information during inpatient rehabilitation for patients with depression. The intervention was evaluated in a sequential control group design. Analyses of covariance were used to assess differences between the control and intervention groups. Changes with respect to illness and treatment beliefs (personal control, treatment control, coherence and concerns about medicines), satisfaction with information about medicines, illness and rehabilitation, and depressive burden were selected as primary outcome measures. We observed significant between-group differences indicating the intervention group's superiority in terms of satisfaction with information regarding medicines. However, the two groups' changes during rehabilitation did not differ in terms of the other outcomes. The intervention resulted in patients judging that their medication information needs had been more thoroughly fulfilled than those patients who received care-as-usual information. However, the intervention did not prove to be effective when the other outcome variables are considered. Taken together and bearing in mind the limitations of our study-particularly the non-randomised design-our results should be replicated in a randomised controlled trial.

Health-care utilization of patients with chronic back pain before and after rehabilitation

BACKGROUND

Patients with chronic back pain show an increased use of health-care services leading to high direct costs. Multidisciplinary rehabilitation reduces pain intensity, depression, disability and work inability. The study aims to investigate whether health-care utilization in patients with chronic back pain is lower after rehabilitation than before rehabilitation and if, in addition to sociodemographic, medical and psychological characteristics, changes in these characteristics immediately after rehabilitation can predict health-care utilization.

METHODS

N = 688 patients with chronic back pain were asked about their overall health-care services use and the use of general practitioners, specialists, physiotherapy, psychotherapy, complementary therapist, massages, and admission to hospital both 6 months before and 6 months after rehabilitation. In addition, various sociodemographic, medical and psychological variables were assessed. To measure changes due to rehabilitation, differences in pain intensity, disability, impairment and coping, quality of life, and days on sick leave before and after rehabilitation were calculated. Dependent t-tests and hierarchical regression analyses were used to analyse the data.

RESULTS

Health-care utilization 6 months after rehabilitation was, except for physiotherapy and psychotherapy, significantly lower than before. The effect sizes were rather small (Cohens'd =. 01-.34). After rehabilitation between 15.2% and 39.9% of the variance of health-care utilization could be explained. The baseline values of health-care utilization explained between 3.2% and 15.9% of the incremental variances. The changes in psychological impairment and coping as well as in sick leave after rehabilitation could explain between 0.8% and 2.9% of the variance of health-care utilization after rehabilitation. Its influence was significant for the general use of health-care services, general practitioners and specialists.

CONCLUSIONS

The results indicate that use of health-care services after rehabilitation in the present study is slightly lower than before, which has an impact on direct costs due to chronic back pain in Germany. The predictors show the importance in terms of health-care utilization of improving work ability and psychological impairment.

Leventhal's common-sense model and asthma control: Do illness representations predict success of an asthma rehabilitation?

This study investigates whether illness representations predict changes in asthma control or vice versa. Illness perceptions and asthma control were assessed in N = 113 asthma patients at the begin/end of an inpatient rehabilitation. Bivariate cross-lagged panel analyses showed that the illness representation dimensions Personal control, Consequences, Coherence, and Emotional representation predicted the change in asthma control, but asthma control did not predict illness representations. In multiple regression analyses with covariates, Personal control still predicted the change in asthma control. Illness beliefs assessed at the beginning of an intervention might help to identify patients with lower probability of treatment success.

Welche Erwartungen sagen postoperative Depressivität und Ängstlichkeit bei herzchirurgischen Patienten am stärksten vorher?

Zusammenfassung. Theoretischer Hintergrund: Depressivität und Ängstlichkeit beeinträchtigen den Behandlungserfolg von herzchirurgischen Patienten. Fragestellung: Untersucht wurde, ob und wie präoperative Patientenerwartungen mit postoperativer Depressivität und Ängstlichkeit zusammenhängen und welche präoperativen Erwartungen hierbei den höchsten prädiktiven Wert haben. Methoden: 124 aortocoronare Bypass-Patienten bearbeiteten eine Woche vor der Operation einen Fragebogen, der verschiedene Aspekte von Erwartungen mischt (Positive Health Expectation Questionnaire; PHES) und einen Fragebogen, der einzelne Erwartungsaspekte getrennt erfasst (Expected Illness Perception Questionnaire, IPQ-E) und eine Woche vor sowie eine Woche nach der Operation Fragen zu ihrer Depressivität und Ängstlichkeit (Hospital Anxiety and Depression Scale (HADS)). Ergebnisse: Postoperative Depressivität wird durch präoperative Erwartungen vorhergesagt (R2 = 0.32, F = 3.13, p = .02). Der einzig signifikante Prädiktor hierbei sind positive Gesundheitserwartungen gemessen mit dem PHES. Auch postoperative Ängstlichkeit wird durch präoperative Erwartungen vorhergesagt (R2 = 0.27, F = 2.55, p < .05). Bei der Vorhersage postoperativer Ängstlichkeit haben erwartete Konsequenzen gemessen mit dem IPQ-E den stärksten prädiktiven Wert. Schlussfolgerungen: Die Studie belegt die Relevanz von präoperativen Erwartungen bei herzchirurgischen Patienten. Interventionen, die auf die Verringerung von Depressivität herzchirurgischer Patienten abzielen, sollten den Fokus auf verschiedene Aspekte von Erwartungen legen. Bei der Verringerung postoperativer Ängstlichkeit könnten hingegen einzeln erfasste Erwartungsaspekte von Bedeutung sein.

The effect of the patient-physician relationship on health-related quality of life after cardiac rehabilitation

Purpose The patient-physician relationship has effects on adherence and health outcomes in chronic diseases. This prospective study investigates the effect of the patient-physician relationship on patients' health-related quality of life (HRQOL) in the context of cardiac rehabilitation. Methods Three hundred and thirty-eight German patients filled out questionnaires at the start and end of rehabilitation and at 6 months follow-up. Patient-physician relationship variables surveyed were patient involvement (perceived involvement in care scales), trust in the physician, patient satisfaction (PHYSAT) and physician's communicative behaviour (KOVA). After adjusting for multiple confounders, hierarchical regression analyses were conducted to predict the influence of the patient-physician relationship on HRQOL after rehabilitation. We further examined clinical relevance using minimal clinically important differences (MCID). Results In the hierarchical regression analyses, 42.8-54.9% of the variance at the end of rehabilitation and 22.4-40.5% at follow-up were explained. The patient-physician variables patient satisfaction, physician's emotionally supportive communication and effective and open communication accounted for 1.4-2.6% of the variance and proved statistically and clinically significant for HRQOL change. Further predictors for better HRQOL were higher income and less trait anger. Conclusion Aspects of the patient-physician relationship are significant predictors for patients' HRQOL after rehabilitation. Rehabilitation physicians should emotionally support the patients and communicate in an effective and open manner to enhance HRQOL. Implications for rehabilitation Aspects of the patient-physician relationship have effects on adherence and clinical outcomes in chronic diseases. In this cardiac sample, the patient-physician relationship had an influence on patients' health-related quality of life (HRQOL) after inpatient rehabilitation. Rehabilitation physicians should emotionally support and encourage the patients and communicate with them in an effective and open manner to enhance patients' HRQOL.

Illness perceptions and personality traits of patients with mental disorders: the impact of ethnicity

OBJECTIVE

To identify differences and similarities between immigrants of Turkish origin and native German patients in therapeutically relevant dimensions such as subjective illness perceptions and personality traits.

METHOD

Turkish and native German mentally disordered in-patients were interviewed in three psychiatric clinics in Hessen, Germany. The Revised Illness Perception Questionnaire (IPQ-Revised) and the Neuroticism-Extraversion-Openness Five-Factor Inventory (NEO-FFI) were used. Differences of scales and similarities by k-means cluster analyses were estimated.

RESULTS

Of the 362 total patients, 227 (123 immigrants and 104 native Germans) were included. Neither demographic nor clinical differences were detected. Socioeconomic gradients and differences on IPQ-R scales were identified. For each ethnicity, the cluster analysis identified four different patient types based on NEO-FFI and IPQ-R scales. The patient types of each ethnicity appeared to be very similar in their structure, but they differed solely in the magnitude of the cluster means on included subscales according to ethnicity.

CONCLUSION

When subjective illness perceptions and personality traits are considered together, basic patient types emerge independent of the ethnicity. Thus, the ethnical impact on patient types diminishes and a convergence was detected.

Assessment of proximal outcomes of self-management programs: translation and psychometric evaluation of a German version of the Health Education Impact Questionnaire (heiQ™)

PURPOSE

This paper describes the translation, cultural adaption, and psychometric evaluation of a German version of the Health Education Impact Questionnaire (heiQ™), a widely used generic instrument assessing a wide range of proximal outcomes of self-management programs.

METHODS

The translation was carried out according to international standards and included forward and backward translations. Comprehensibility and content validity were tested using cognitive interviews with 10 rehabilitation inpatients. Psychometric properties were examined in rehabilitation inpatients (n = 1,202) with a range of chronic conditions. Factorial validity was assessed using confirmatory factor analysis; concurrent validity was explored by correlations with comparator scales.

RESULTS

The items of the German heiQ™ were well understood by rehabilitation inpatients. The structure of the eight heiQ™ scales was replicated after minor adjustment. heiQ™ scales had higher correlations with comparator scales with similar constructs, particularly mental health concepts than with physical health. Moreover, all heiQ™ scales differentiated between individuals across different levels of depression.

CONCLUSION

The German heiQ™ is comprehensible for German-speaking patients suffering from different types of chronic conditions; it assesses relevant outcomes of self-management programs in a reliable and valid manner. Further studies involving its practical application are warranted.

Illness beliefs, treatment beliefs and information needs as starting points for patient information--evaluation of an intervention for patients with chronic back pain

OBJECTIVE

The objective of the study was to evaluate an intervention which applied the extended Common Sense Model to the provision of information about illness and treatment during inpatient rehabilitation for patients with chronic back pain.

METHODS

The intervention was evaluated in a sequential control group design (control group N=105; intervention group N=96). Changes with respect to illness and treatment beliefs, satisfaction with information, and health status at the end of rehabilitation were selected as outcome measures. Analyses of covariance were used to assess differences between control and intervention group.

RESULTS

Significant time-by-group interactions were shown for causal beliefs, personal control, satisfaction with information about illness and rehabilitation, and for general health. All time-by-group interactions indicated superiority of the intervention group.

CONCLUSION

The intervention group assessed their back pain as personally controllable and their information needs at the end of rehabilitation as being met to a greater extent than did patients who received care as usual.

PRACTICE IMPLICATIONS

The extended Common Sense Model seems promising as a frame for discussing illness and treatment perceptions as well as information needs in patients with chronic back pain.

Illness beliefs and treatment beliefs as predictors of short and middle term outcome in depression

The article investigates whether illness beliefs and beliefs about rehabilitation are predictors of short and middle term outcome in depression even when adjustments are made for variables, which are known to be predictors of the course of depression. Within the context of a non-controlled prospective study design, data were analyzed using forced entry hierarchical multiple regression analyses. The sample comprised N = 98 patients. Adjusting for a range of sociodemographic and medical predictors, illness beliefs and beliefs about rehabilitation predict outcome in depression. Illness beliefs and beliefs about rehabilitation are relevant starting points for designing patient-oriented interventions.

Validation of the Illness Perception Questionnaire for Schizophrenia in a German-speaking sample of outpatients with chronic schizophrenia

BACKGROUND

Because the mere definition of insight from the therapist's viewpoint may not be sufficient to identify treatment targets for adherence enhancement, we need assessment strategies which are more sensitive to the patient's perspective. Illness perception (IP), defined as the beliefs a patient holds about his/her health problems, has been shown to affect coping in the context of a physical or mental illness, e.g. compliance behaviour. To assess IP in people diagnosed with schizophrenia, the Illness Perception Questionnaire for Schizophrenia (IPQS) was developed. The aim of the present study was to analyse the psychometric properties of the German version of the IPQS.

SAMPLING AND METHODS

The study sample consisted of 128 German-speaking outpatients suffering from chronic schizophrenia or schizoaffective disorder. To achieve comparability with the validation of the English scale version, the same constructs were assessed: psychopathology, depression, and beliefs about medication. Furthermore, insight into one's illness was assessed. Internal consistency, test-retest reliability and construct validity including convergent and discriminant validity were analysed.

RESULTS

Five of eight IPQS subscales were found to be internally reliable and all subscales demonstrated high stability over time. Correlations with validity measures indicated that the subscales assess dimensions of a construct, which is distinct from psychopathology, depression, beliefs about medication and insight, except for the Identity subscale which substantially overlapped with measures of insight.

CONCLUSIONS

The German version of the IPQS is an essentially reliable and valid measure of IP for German-speaking people with a schizophrenia spectrum disorder. This may encourage its usage in further studies investigating the impact of subjective beliefs about mental health problems on outcome and recovery in schizophrenia.
