A systematic review of illness representation clusters in chronic conditions

Illness perceptions and blood pressure control among hypertensive Filipino Americans: A cross-sectional study

BACKGROUND

Among Asian Americans, Filipino Americans (FAs)-who constitute the fourth largest US immigrant group and who fill in health care workforce shortages-experience high prevalence but low control rates of high blood pressure (HBP). Research reveals that patients' illness perceptions, their common-sense model (CSM) of the illness, influence treatment behaviors, and management outcomes. However, scarce information exists about FAs' perceptions about HBP.

PURPOSE

To address this gap, we conducted a cross-sectional study to (a) identify the illness perceptions of hypertensive FAs, (b) classify these perceptions into clusters, and (c) determine the association between illness perceptions and BP control.

METHODOLOGY

The responses of 248 FAs with HBP to the Brief Illness Perception Questionnaire were analyzed using JMP Pro version 17 to discover their CSMs or illness perceptions. We used iterative K means cluster analysis to classify variations in CSMs and analysis of means chart to determine the association of illness perceptions and BP control.

RESULTS

Hypertensive FAs expressed threatening (negative) views of HBP through their emotional perceptions of the illness and its chronic time line, whereas their positive views centered on their cognitive beliefs about understanding HBP and its controllability. Based on the biomedical model of HBP, the overall illness perceptions or CSMs encompassed three clusters. Generally, threatening illness perceptions were associated with stage 2 HBP.

CONCLUSIONS/IMPLICATIONS

The findings underscore the need for nurse practitioners to elicit, listen, discern, and understand the illness perceptions or CSMs of hypertensive FAs to improve BP treatment and control with scientifically and culturally tailored interventions.

Prospective Associations Between Personality Traits and Major Depressive Disorder Symptom Severity: The Mediating Role of Illness Representations

Major depressive disorder (MDD) patients' personality traits and illness representations are linked to MDD severity. However, the associations between personality and illness representations in MDD and the mediating role of illness representations between personality and MDD severity have not been investigated. This study aimed to prospectively investigate the aforementioned associations and the possible mediating role of illness representations between personality and MDD severity. One hundred twenty-five patients with a MDD diagnosis, aged 48.18 ± 13.92 (84% females), participated in the study. Personality traits were measured with the Traits Personality Questionnaire at baseline. Illness representations were measured with the Illness Perception Questionnaire-Mental Health about five months later (mean = 5.08 ± 1.14 months). MDD severity was measured about 10 months after the baseline assessment (mean = 9.53 ± 2.36 months) with the Beck Depression Inventory. SPSS 29 and AMOS 27 were used to conduct correlational and parallel mediation analyses. According to the results, Neuroticism was positively and Extraversion was negatively linked to MDD severity. Negative MDD impact representations fully mediated these associations. Neuroticism and Extraversion are linked to future MDD severity through patients' representations of MDD's impact. Restructuring maladaptive representations about MDD's impact can be a promising way to reduce symptom severity in patients with high Neuroticism and low Extraversion levels.

Gestational diabetes perception profiles based on attachment style: a cross-sectional study

AIMS

Gestational diabetes (GDM) is a prevalent complication in pregnancy that requires effective self-management, which can be influenced by illness perceptions. Moreover, behavioral regulation can be affected by attachment styles. Thus, our study aimed to identify common GDM perception profiles and test their association with attachment styles.

METHODS

In this cross-sectional study, 446 women completed the Relationship Questionnaire (RQ), the Brief Illness Perception Questionnaire (BIPQ), and additional items about GDM diagnosis, information, competence, adherence, behavioral change. Latent profile analysis (LPA) was conducted to determine GDM perception profiles. Multinomial logistic regression followed to calculate the association between GDM perception profiles and attachment styles.

RESULTS

Three distinct profiles emerged: coping (n = 172, 38.6%)-characterized by the most positive GDM perception, burdened (n = 222, 49.8%)-indicating the emotional burden of the disease, and resourceless (n = 52, 11.7%)-reporting lack of resources (i.e. information, competence). Women with insecure attachment styles were more likely to develop a burdened GDM perception profile. Specifically, the expression of a fearful (OR = 1.184 [95%CI: 1.03; 1.36], p = 0.016) and a preoccupied (OR = 1.154 [95%CI: 1.01; 1.32], p = 0.037) attachment style increased the likelihood for a burdened perception profile, while a secure attachment style (OR = 10.791 [95%CI: 0.65; 0.96], p = 0.017) decreased likelihood for developing resourceless GDM perception profile.

CONCLUSIONS

Three GDM perception profiles were identified and the role of attachment styles in shaping these perceptions was confirmed. Further studies are needed to investigate whether a tailored treatment approach based on the predominant attachment style could lead to more positive GDM perceptions, improved glycemic control, and better perinatal outcomes.

Symptom characteristics, perceived causal attributions, and contextual factors influencing self-care behaviors: An ecological daily assessment study of adults with chronic illness

OBJECTIVE

Insights into how symptoms influence self-care can guide patient education and improve symptom control. This study examined symptom characteristics, causal attributions, and contextual factors influencing self-care of adults with arthritis, asthma, chronic obstructive pulmonary disease, diabetes, or heart failure.

METHODS

Adults (n = 81) with a symptomatic chronic illness participated in a longitudinal observational study. Using Ecological Daily Assessment, participants described one symptom twice daily for two weeks, rating its frequency, severity, bothersomeness, duration, causes, and self-care.

RESULTS

The most frequent symptoms were fatigue and shortness of breath. Pain, fatigue, and joint stiffness were the most severe and bothersome. Most participants engaged in active self-care, but those with fatigue and pain engaged in passive self-care (i.e., rest or do nothing), especially when symptoms were infrequent, mild, somewhat bothersome, and fleeting. In people using passive self-care, thoughts, feelings, and the desire to conceal symptoms from others interfered with self-care.

CONCLUSION

Most adults with a chronic illness take an active role in managing their symptoms but some conceal or ignore symptoms until the frequency, severity, bothersomeness, or duration increases.

PRACTICE IMPLICATIONS

When patients report symptoms, asking about self-care behaviors may reveal inaction or ineffective approaches. A discussion of active self-care options may improve symptom control.

"Am I different?" Coping and mental health among teenagers with adolescent idiopathic scoliosis: A qualitative study

PURPOSE

To explore the stressors, coping strategies, and mental health of adolescents diagnosed with idiopathic scoliosis.

DESIGN AND METHODS

This study adopted a descriptive qualitative study design. Twelve participants were recruited from a local non-government organization in Hong Kong. Semi-structured interviews were conducted to collect data. Verbatim transcriptions of interviews were coded and analyzed using thematic analysis. The guideline of the Consolidated Criteria for Reporting Qualitative Studies was used to report the findings.

RESULTS

Five themes were identified: "Disease- and treatment-induced changes and stressors", "Cognitive assessment and personal perceptions", "Behavioral and emotional coping strategies", "Social interactions and social support", and "Deteriorating or thriving in psychological development and well-being".

CONCLUSIONS

Adolescents with idiopathic scoliosis experienced a variety of physical and psychological stressors. It is imperative to prioritize efforts to promote adaptive coping and activate social support systems to achieve better outcomes in this population.

PRACTICAL IMPLICATIONS

Healthcare providers should aim to comprehend the experiences of adolescents with idiopathic scoliosis for improved clinical interactions and holistic care. Future research should prioritize coping-based interventions, to enhance adaptive coping behaviors and the well-being of this population.

Can illness representations be used to understand pain experienced in breast cancer survivorship-a cross-sectional study

BACKGROUND

Chronic pain is a recognised long-term consequence associated with breast cancer and its treatment; however, it is often underdiagnosed and undertreated. This study aims to explore the associations between illness representations, chronic cancer pain, and HRQoL in women who have survived breast cancer.

DESIGN AND METHODS

A cross-sectional online survey design was used. Data from 182 women who participated in the survey were analysed.

RESULTS

Chronic cancer pain was reported by 66% of respondents. Using the BPI-SF (score 0-10), participants were categorised into one of four pain categories: no chronic pain (BPI score 0; 34.1%), mild pain (BPI score 1-3; 35.7%), moderate pain (BPI score 4-6; 25.3%), and severe pain (BPI score 7 + ; 4.9%). The main findings were that having a strong illness identity (IPQ-R subscale which assesses the number of symptoms an individual attributes to their illness) was found to be a significant predictor of pain severity (OR 1.21 (95% CI 1.07-1.37), p = 0.003). Furthermore, HRQoL was significantly associated and predictive of pain severity (OR 0.97 (95% CI 0.95-0.99), p < 0.001). An additional finding was that not being in paid work was strongly associated with being in a higher pain category (OR 5.92 (95% CI 1.84-19.05), p = 0.003).

CONCLUSIONS

The findings of this study highlight the high prevalence of chronic cancer pain experienced by this population. Results show that dimensions of illness representations are associated with chronic cancer pain experienced by breast cancer survivors. Furthermore, having a strong illness identity and HRQoL were found to be independent, significant predictors of pain severity.

IMPLICATIONS FOR CANCER SURVIVORS

These findings demonstrate that chronic pain is an unmet clinical need experienced by breast cancer survivors, which is associated with reduced overall HRQoL. Therefore, consideration is needed regarding the assessment and management of chronic pain experienced by this population.

Prognostic value of illness perception on changes in knee pain among elderly individuals: Two-year results from the Frederiksberg Cohort study

Objective

To investigate the prognostic value of illness perception (IP) on knee pain, quality of life (QoL) and functional level in elderly individuals reporting knee pain.

Design

A prospective cohort study of 1552 elderly with knee pain comparing two previously established clusters based on the Brief Illness Perception questionnaire. Cluster 1 ("Concerned optimists" [hypothesized unfavorable profile]; n ​= ​642) perceived their knee pain as a greater threat to them than Cluster 2 ("Unconcerned confident" [hypothesized favorable profile]; n ​= ​910). Primary outcome was the change from baseline to year 2 in the KOOS Pain subscale. Secondary outcomes were changes from baseline in quality of life (EuroQol-5 Domain and EQ VAS) and in the KOOS subscales Symptom, Activities of Daily Living, Knee-related QoL and Sports and recreation. Analyses were done on the original Intention-To-Survey (ITS) population, using repeated measures mixed linear models.

Results

Among the ITS population, 841 (54%) responded to the 2-year survey. There was a statistically significant but clinically irrelevant cluster difference in the 2-year change from baseline in KOOS pain (mean difference: 6.0 KOOS points [95% CI: 7.3 to -4.7]) explained by a minor improvement in Cluster 1: (6.2 points) and no changes in Cluster 2: (0.2 points). Comparable results were found across the secondary outcomes. Clinically irrelevant cluster changes in IP were seen.

Conclusion

In a cohort of people with knee pain, IP phenotype (i.e., Clusters) were of no prognostic value for the 2-year changes in pain, function, and QoL. Targeting IP may not be relevant in this patient population.

Trial registration number and date of registration

The Frederiksberg Cohort study was pre-registered at clinicaltrials.gov (NCT03472300) on March 21, 2018.

Healing profiles in patients with a chronic diabetic foot ulcer: An exploratory study with machine learning

Diabetic foot ulcers (DFU) are one of the most frequent and debilitating complications of diabetes. DFU wound healing is a highly complex process, resulting in significant medical, economic and social challenges. Therefore, early identification of patients with a high-risk profile would be important to adequate treatment and more successful health outcomes. This study explores risk assessment profiles for DFU healing and healing prognosis, using machine learning predictive approaches and decision tree algorithms. Patients were evaluated at baseline (T0; N = 158) and 2 months later (T1; N = 108) on sociodemographic, clinical, biochemical and psychological variables. The performance evaluation of the models comprised F1-score, accuracy, precision and recall. Only profiles with F1-score >0.7 were selected for analysis. According to the two profiles generated for DFU healing, the most important predictive factors were illness representations on T1 IPQ-B (IPQ-B ≤ 9.5 and < 10.5) and the DFU duration (≤ 13 weeks). The two predictive models for DFU healing prognosis suggest that biochemical factors are the best predictors of a favorable healing prognosis, namely IL-6, microRNA-146a-5p and PECAM-1 at T0 and angiopoietin-2 at T1. Illness perception at T0 (IPQ-B ≤ 39.5) also emerged as a relevant predictor for healing prognosis. The results emphasize the importance of DFU duration, illness perception and biochemical markers as predictors of  healing in chronic DFUs. Future research is needed to confirm and test the obtained predictive models.

Depression and anxiety mediate the relationship between illness representations and perceived distress in patients with chronic pain

Illness representations explain the individual's perception and processing of health-related information. In a chronic condition such as persistent pain, illness representations might influence treatment adherence and outcome. This study aims to exploratively identify illness representations of patients with chronic pain and their association to mental disorders and subjective distress. 95 participants admitted to an inpatient university clinic were included. Validated instruments were used to assess illness representations (IPQ-R), mental health disorders (PHQ-D), and subjective distress (PSQ). Sociodemographic data and scores for the instruments were first inspected descriptively. Correlation, regression, and mediator analyses were conducted. Analyses indicated that the distributions of the IPQ-R range toward higher values. In regard to mental disorders (PHQ-D) and subjective distress (PSQ), we found several significant correlations with subscales of the IPQ-R. A regression analysis showed the IPQ-R subscales personal control, emotional representation and sex (males) to be significant predictors of subjective distress measured with the PSQ (F(11,86) = 11.55, p < .001, adjusted R2 = 0.545). Depression, anxiety, and stress syndromes (PHQ-D) significantly mediated the positive association between emotional representations (IPQ-R, predictor) and subjective distress (PSQ, outcome) with a total effect of c = .005, 95% CI [.005; .129]. Illness representations play a significant role in evaluating patients' subjective distress and mental health. It is advised to incorporate illness representations into standard protocols for psychological interventions to comprehend their influence on targeted therapeutic strategies, particularly those tailored for pain management.

Factors associated with illness representations in adults with epileptic and functional seizures: A systematic review

Illness representations refer to a person's beliefs about their health condition and are thought to influence clinical outcomes. By understanding factors related to illness representations, potentially modifiable targets for psychological intervention can be identified. The aim of this systematic review was to synthesise the literature on factors associated with illness representations in people with epilepsy and functional seizures. Three electronic databases (Psychinfo, EMBASE, and Proquest (Theses and dissertations)) were searched for studies that reported on associations between Illness Perception Questionnaire scores (or variations thereof) and biopsychosocial factors in people with epilepsy or people with functional seizures. Seventeen studies met inclusion criteria and were assessed with a bespoke quality appraisal tool. Overall, there was moderately strong evidence for an association between more threatening illness representations and poorer clinical outcomes relating to seizure characteristics, distress, coping, and quality of life; the evidence for these relationships was stronger for people with epilepsy than functional seizures. There was no clear difference between the illness representations of the two groups. The results of this review highlight the clinical importance of illness representations in people with seizure disorders, as well as opportunities for further research.

Identification of illness representational patterns and examining differences of self-care behavior in the patterns in chronic kidney disease

Self-care behavior is considered important for preventing the progression of chronic kidney disease (CKD). Although lifestyle interventions are popular, they have not been sufficiently effective. According to studies on other chronic diseases, illness representation has been found to formulate a pattern, and self-care behavior could differ depending on the pattern, which suggests difference in self-care behavior based on illness representation. This study examined what kind of illness representational patterns exist among CKD patients and whether there is a difference in self-care behavior depending on the pattern. A survey was conducted from the beginning of June to the end of October 2019 on 274 CKD patients who were either outpatients or hospitalized at general hospitals in Western Japan. The Illness Perception Questionnaire-Revised was used to assess illness representation and the Japanese Chronic Kidney Disease Self-Care scale was used to assess self-care behavior. Two-stage cluster analysis was used to identify clusters. Cluster features were examined using analysis of variance and Tukey HSD tests. Differences in self-care behavior scores among identified clusters were investigated. Two hundred and forty-four questionnaires were received, and 212 were analyzed. Participants were aged 64.9±12.9, and the estimated glomerular filtration rate was 33.7±15.8. Three clusters were identified: Cluster 1 represented the difficulty of making sense of the changed condition caused by the disease and easily falling into misunderstanding; Cluster 2 represented patients with disease conditions that impacted their daily life and emotional responses; Cluster 3 represented the controllability and understandability of the disease. Total self-care behavior scores indicated a significant difference between Cluster 1 (52.1 ± 9.7) and Cluster 3 (57.7 ± 8.2). In conclusion, we showed that three representational patterns exist among CKD patients. In addition, a difference was found in self-care behavior depending on the illness representational pattern, suggesting the need to focus on illness representation.

Evaluation of a Digital Self-management Platform for Patients With Chronic Illness in Primary Care: Qualitative Study of Stakeholders' Perspectives

BACKGROUND

Population aging and multimorbidity has led to increasing chronic care needs associated with new challenges in managing growing costs, rising health care professional workloads, and the adoption of rigorous guidelines. These issues could all benefit from greater digitalization and a more patient-centered approach to chronic care, a situation brought to the fore by the COVID-19 pandemic. Little is known about real-life use in primary care.

OBJECTIVE

This study aimed to explore the views, thoughts, usability, and experiences concerning a recently introduced digital self-care platform for chronic conditions in 3 Dutch primary care practices.

METHODS

We conducted an explorative study combining questionnaires and interviews among patients and general practitioners from 3 general practices that used the digital platform. Questionnaires were sent to patients in each practice to seek the views and experiences of both patient nonusers (n=20) and patient users (n=58) of the platform, together with standardized questionnaires about illness perception and quality of life. In addition, patients (n=15) and general practitioners (n=4) who used the platform took part in semistructured interviews. We transcribed interviews verbatim and performed qualitative content analysis using a deductive approach. The results of the questionnaires were analyzed with descriptive analysis.

RESULTS

Among patients who had not actively used the platform but had received an explanation, only 35% (7/20) would recommend its use due to concerns over communication and handling. However, this percentage increased to 76.3% (45/59) among the people who actively used the platform. Interviews with patients and general practitioners who used the platform uncovered several key benefits, including reduced time requirements, reduced workload, improved care quality, and improved accessibility due to the greater patient-centeredness and use of different communication tools. In addition, the self-management tool led to greater patient autonomy and empowerment. Although users considered the platform feasible, usable, and easy to use, some technical issues remained and some patients expressed concerns about the reduction in human contact and feedback.

CONCLUSIONS

The overall experience and usability of the platform was good. Support for the online self-management platform for chronic care increased when patients actively used the tool and could experience or identify important advantages. However, patients still noted several areas for improvement that need to be tackled in future iterations. To ensure benefit in the wider population, we must also evaluate this platform in cohorts with lower digital and health literacy.

Effect of social support on illness perception in patients with atrial fibrillation during "Blanking Period": Mediating role of sense of mastery

AIM

To explore whether sense of mastery can mediate the relationship between social support and illness perception in patients with atrial fibrillation (AF) who were at the "Blanking Period."

DESIGN

A cross-sectional design.

METHODS

405 patients with AF who were at the "Blanking Period" in the Affiliated Hospital of Qingdao University were recruited; they completed a set of questionnaires, including the Perceived Social Support Scale, the Personal Mastery Scale and the Brief Illness Perception Questionnaire.

RESULTS

Social support and sense of mastery were both adversely connected to illness perception. The indirect effect of social support on illness perception through sense of mastery was negative, accounting for 86.04% of the total effect.

CONCLUSION

During the "Blanking Period," better social support and sense of mastery contribute to a positive illness perception of AF patients. Social support also can influence patients' illness perception indirectly via the mediator of sense of mastery.

Atrial fibrillation, quality of life and distress: a cluster analysis of cognitive and behavioural responses

PURPOSE

Few studies have examined specific cognitive and behavioural responses to symptoms, which may impact health-related outcomes, in conjunction with illness representations, as outlined by the Common-Sense-Model. Patients with atrial fibrillation (AF) report poor quality-of-life (QoL) and high distress. This cross-sectional study investigated patterns/clusters of cognitive and behavioural responses to illness, and illness perceptions, and relationships with QoL, depression and anxiety.

METHODS

AF patients (N = 198) recruited at cardiology clinics completed the AF-Revised Illness Perception Questionnaire, Atrial-Fibrillation-Effect-on-Quality-of-Life Questionnaire, Patient Health Questionnaire-8 and Generalized Anxiety Disorder Questionnaire. Cluster analysis used Ward's and K-means methods. Hierarchical regressions examined relationships between clusters with QoL, depression and anxiety.

RESULTS

Two clusters of cognitive and behavioural responses to symptoms were outlined; (1) 'high avoidance'; (2) 'low symptom-focussing'. Patients in Cluster 1 had lower QoL (M = 40.36, SD = 18.40), greater symptoms of depression (M = 7.20, SD = 5.71) and greater symptoms of anxiety (M = 5.70, SD = 5.90) compared to patients in Cluster 2 who had higher QoL (M = 59.03, SD = 20.12), fewer symptoms of depression (M = 3.53, SD = 3.56) and fewer symptoms of anxiety (M = 2.56, SD = 3.56). Two illness representation clusters were outlined; (1) 'high coherence and treatment control', (2) 'negative illness and emotional representations'. Patients in Cluster 2 had significantly lower QoL (M = 46.57, SD = 19.94), greater symptoms of depression (M = 6.12, SD = 5.31) and greater symptoms of anxiety (M = 4.70, SD = 5.27), compared with patients in Cluster 1 who had higher QoL (M = 61.52, SD = 21.38), fewer symptoms of depression (M = 2.85, SD = 2.97) and fewer symptoms of anxiety (M = 2.16, SD = 3.63). Overall, clusters of cognitive and behavioural responses to symptoms, and illness perceptions significantly explained between 14 and 29% of the variance in QoL, depression and anxiety.

CONCLUSION

Patterns of cognitive and behavioural responses to symptoms, and illness perceptions are important correlates of health-related outcomes in AF patients.

Profiles of adult people in a Spanish sample with chronic pain: Cluster analysis

AIM

To establish groups of people with chronic non-cancer pain according to the impairment caused by pain and to identify factors associated with the group with a higher level of impairment.

BACKGROUND

Knowing the profiles of people who suffer from chronic non-cancer pain could make it possible to direct their treatment and to detect associated risks.

DESIGN

A cross-sectional study.

METHODS

A sample of 395 people with chronic non-cancer pain was collected in Pain Units and Primary Healthcare Centres in southern Spain (January to March 2020). A cluster analysis was performed to divide the population into groups and a binary logistic regression model was established to determine factors associated with the group with a higher level of impairment.

RESULTS

Two groups were identified: lower level of impairment due to pain, characterized by being 45-65 years old, not medicated with opioids or anxiolytics, employed and with a mild level of impact on daily life; and higher level of impairment characterized by being older than 65 years old, medicated with opioids and anxiolytics, retired or on medical leave and with a severe impact on daily life. In addition, among women, being widowed, single or a smoker are risk factors for belonging to the group with a higher level of impairment; being smokers or consuming alcohol three or less times a week would be risk factors in men.

CONCLUSIONS

Age, chronic non-cancer pain impact on daily life, work situation and the consumption of opioid drugs and/or anxiolytics are factors that appear to influence the level of impairment due to chronic pain.

IMPACT

These findings could help detect impairment due to pain in its early stages, determining the specific needs of each person.

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.

How I see is how I feel. Identification of illness perception schema and its association with adaptation outcomes in multiple sclerosis - a 5-year prospective study

The aim of the study was to assess the role of illness perception in adaptation to chronic disease among patients with relapsing-remitting multiple sclerosis (RRMS). The differences between the obtained configurations of the illness perception components during four measurements and the model of predictions of the values of adaptation indicators, i.e. depression, anxiety and quality of life during subsequent measurements, were analyzed. Illness representation was assessed at baseline via the Illness Representation Questionnaire–Revised. The adaptation indicators–anxiety, depression (measured by HADS) and quality of life (measured by MSIS-29) were measured at baseline and three more times over a five-year period. The k-means cluster analysis (with two-way and repeated measures ANOVA) was conducted in a group of 90 patients (48.89% women and 51.11% men). Subsequently, the mean values of depression, anxiety, physical and psychological quality of life were compared between the clusters using the Kruskall-Wallis test. Finally, a cross-lagged panel modeled for HADS and MSIS-29 subscales in each measurement occasion (T1-T4). Three different illness perception clusters (Anxious, Realistic and Fatalistic Illness Perception named AIP, RIP and FIP) were composed which differentiated the depression, anxiety, quality of life level and age. FIP showed the lowest adaptation outcomes with small differences between AIP and RIP. It was also significantly characterized by the highest age. The positive adaptation indicators were related to the RIP cluster. The model presented rather satisfactory fit (χ²(48) = 81.05; CFI = .968; TLI = .925; SRMR = .050) with slightly inflated RMSEA = .087 (90%CI .053-.120). Based on initial measurements of individual characteristics, it was possible to predict the functioning of patients after several years. For patients with AIP, the covariance of anxiety and depression was significant, for patients with RIP–depression and anxiety, and for patients with FIP–depression. In addition, each of the variables was a predictor of subsequent measurements in particular time intervals, illustrating the dynamics of changes. Results highlight that illness perceptions formed at the beginning of RRMS are important for the process of adaptation to the disease. Moreover, they showed the differences between the adaptation outcomes supporting the idea that a cognitive representation might be important for the level of psychological functioning.

Illness representations and psychological outcomes in chronic lymphocytic leukaemia

OBJECTIVES

Chronic lymphocytic leukaemia (CLL) is a lifelong cancer with subtle symptoms. Treatment is not curative and often involves repeated relapses and retreatments. Illness perceptions - cognitive and emotional representations of illness stimuli - were studied in CLL patients to: 1) identify illness perception 'profiles' prior to treatment; and 2) test whether profile membership predicts psychological responses 12 months later as treatment continued.

DESIGN

CLL patients (N = 259), randomized to one of four cancer treatment trials testing targeted therapy, were assessed before starting treatment and at 12 months.

METHODS

The Brief Illness Perception Questionnaire (BIPQ) assessed perceived consequences, timeline, personal/treatment control, identity, comprehension, concern, and emotions toward CLL. Psychological outcomes were depressive symptoms (PHQ-9/BDI-II), negative mood (POMS), and cancer stress (IES-R). Latent profile analysis (LPA) determined number of profiles and differential BIPQ items for each profile. Multilevel models tested profiles as predictors of 12-month psychological outcomes.

RESULTS

LPA selected the three-profile model, with profiles revealing Low (n = 150; 57.9%), Moderate (n = 21; 8.1%), and High-impact (n = 88; 34.0%) illness representations. Profiles were defined by differences in consequences, identity, concern, and emotions. Profile membership predicted all psychological outcomes (ps<.038). Low-impact profile patients endorsed minimal psychological symptoms; High-impact profile patients reported substantial symptoms.

CONCLUSIONS

Results of the first CLL illness representation study provide directions for future clinical efforts. By identifying differences among patients' perceptions of CLL consequences, symptom burden, concerns, and emotional responses, an at-risk patient group might receive tailored psychological treatment. Treatments may address negative perceptions, to reduce psychological risk associated with chronic cancer.

Illness perception in patients with eating disorders: clinical, personality, and food addiction correlates

PURPOSE

Although the role of illness perception in the clinical course of many physical diseases and certain mental disorders has been well described, little is known about illness perception in eating disorders (ED) so far. Therefore, the purpose of this study was to extend our understanding of illness perception in different ED diagnostic types and to explore its association between clinical, psychopathological, motivational, personality, and food addiction (FA) features.

METHODS

The sample consisted of 104 patients with ED [(23 anorexia nervosa (AN), 39 bulimia nervosa (BN), 19 binge eating disorder (BED), and 23 other specified feeding and eating disorders (OSFED)]. Illness perception was assessed by means of the revised version of the Illness Perception Questionnaire (IPQ-R).

RESULTS

The results supported the association between illness perception and clinical, psychopathological, and personality factors. Patients with BN and BED showed greater illness perception than the other types. Improved illness perception was positively associated with a longer duration of the disorder and FA. Furthermore, a relevant finding suggests that at least half of the patients with ED did not achieve a good level of illness perception until after having the disorder for 20 years on average.

CONCLUSION

Our findings suggest that higher levels of FA and longer duration of the ED are positively and directly associated with increased illness perception. This may explain the low levels of initial motivation in these patients and their high dropout rates in the early stages of treatment.

Illness perception and health care use in individuals with irritable bowel syndrome: results from an online survey

BACKGROUND

Individual illness perception is known to influence a range of outcome variables. However, little is known regarding illness perception in irritable bowel syndrome (IBS) and its relation to the use of the health care system. This study hypothesised a relationship between illness perception and inappropriate health care use (under-, over- and misuse).

METHODS

An internet-based, cross-sectional study in participants affected by IBS symptoms was carried out (April - October 2019) using open questions as well as validated standardized instruments, e.g. the illness perception questionnaire revised (IPQ-R) and its subscales. Sub-group comparisons were done non-parametrically and effect sizes were reported. Potential predictors of (1) conventional health care utilisation and (2) utilisation of treatment approaches with lacking or weak evidence regarding effectiveness in IBS were examined with logistic regression analyses and reported as odds ratio (OR) and 95% confidence interval.

RESULTS

Data from 513 individuals were available. More than one-third (35.7%) of participants were classified as high utilisers (> 5 doctor visits during the last year). Several indicators of inappropriate health care use were detected, such as a low proportion of state-of-the-art gynaecological evaluation of symptoms (35.0% of women) and a high proportion of individuals taking ineffective and not recommended non-steroidal antirheumatic drugs for IBS (29.4%). A majority (57.7%) used treatment approaches with lacking or weak evidence regarding the effectiveness in IBS (e.g. homeopathy). Being a high utiliser as defined above was predicted by the perceived daily life consequences of IBS (IPQ-R subscale "consequences", OR = 1.189 [1.100-1.284], p ≤ 0.001) and age (OR = 0.980 [0.962-0.998], p = 0.027). The use of treatment approaches with lacking or weak evidence was forecasted by the perceived daily life consequences (OR = 1.155 [1.091-1.223], p ≤ 0.001) and gender (reference category male: OR = 0.537 [0.327-0.881], p = 0.014), however effect sizes were small.

CONCLUSIONS

Daily life consequences, perceived cure and personal control as aspects of individual disease perception seem to be related to individuals' health care use. These aspects should be a standard part of the medical interview and actively explored. To face inappropriate health care use patients and professionals need to be trained. Interdisciplinary collaborative care may contribute to enhanced quality of medical supply in IBS.

Distinct Illness Representation Profiles Are Associated With Anxiety in Women Testing Positive for Human Papillomavirus

Background

Testing positive for human papillomavirus (HPV) at cervical cancer screening has been associated with heightened anxiety. To date, the cognitive determinants of heightened anxiety remain unclear, making it difficult to design effective interventions.

Purpose

This study investigated latent illness representation profiles in women testing positive for HPV with no abnormal cells (normal cytology) and explored associations between these profiles and anxiety.

Methods

Women aged 24–66 (n = 646) who had tested HPV-positive with normal cytology at routine HPV primary screening in England completed a cross-sectional survey shortly after receiving their result.

Results

Latent profile analysis identified three distinct profiles of illness representations (termed “adaptive,” “negative,” and “negative somatic”), which differed significantly in their patterns of illness perceptions. Hierarchal linear regression revealed that these latent illness representation profiles accounted for 21.8% of the variance in anxiety, after adjusting for demographic and clinical characteristics. When compared with adaptive representations (Profile 1), women with negative representations (Profile 2) and negative somatic representations (Profile 3) had significantly higher anxiety, with clinically meaningful between-group differences (mean difference [MD] = 17.26, confidence interval [CI]: 14.29–20.22 and MD = 13.20, CI: 9.45–16.96 on the S-STAI-6, respectively).

Conclusion

The latent illness representation profiles identified in this study provide support for the role of negative beliefs contributing to anxiety in women testing HPV-positive with normal cytology. Characteristics specific to subgroups of highly anxious women (Profiles 2 and 3) could be used by policymakers to target information in routine patient communications (e.g., test result letters) to reduce unnecessary burden. Future research should adopt longitudinal designs to understand the trajectory of illness representations from HPV diagnosis through to clearance versus persistence.

Illness perceptions of Israeli hospitalized patients with acute coronary syndrome

BACKGROUND

Illness perceptions (IPs) can affect cardiac health behaviours and outcomes.

AIMS AND OBJECTIVES

To investigate IPs among patients hospitalized with acute coronary syndrome (ACS).

DESIGN

Longitudinal survey.

METHODS

The ACS Israel Study is a national, biennial registry, enrolling all patients with ACS admitted to cardiac intensive care or cardiology wards in Israel within a 2-month period. Data includes demographics, medical history, and treatment for ACS using an electronic database. In 2018, a nursing component was added, including the Brief Illness Perception Questionnaire. Data were analysed using descriptive statistics and a two-stage cluster analysis.

RESULTS

A total of 990 subjects were surveyed. Mean age was 62.8 (SD = 12.5) and most respondents were male and married. Mean IP scores ranged from 3.28 to 6.06. Three clusters were found; one only of women and two only of men (one cluster with lower IPs and little previous medical history and cardiac risk factors and the second with higher IPs, greater medical history, and cardiac risk factors. Those with higher education scored lower on several IPs.

CONCLUSIONS

Subjects were moderately cognitively and emotionally impacted by their illness. Men tended to perceive their illness as having either a relatively strong or a relatively weak emotional and cognitive impact on their lives, where women were somewhere in-between. Participants with an academic education perceived less of an impact of the illness while those with a previous history of chronic disease reported the opposite. It is recommended that educational interventions and in-depth qualitative studies be designed that investigate the development of IPs during hospitalization to potentially improve cardiac health behaviours, especially among those without a previous medical history and cardiac risk factors.

RELEVANCE TO CLINICAL PRACTICE

Those without a history of chronic disease or a lower level of education are less likely to absorb the full impact of a cardiac event while hospitalized and should, therefore, be monitored more closely and coached with greater intensity than other groups while still in-hospital.

Illness Representation and Self-Efficacy: An Exploration of Fatigue Factors in Middle-Aged Stroke Survivors

The purpose of this study is twofold: to examine the relationship between illness representation and self-efficacy and to test the determinants and the effect of self-efficacy, resilience, and stroke impact on fatigue in middle-aged stroke survivors. This study used a cross-sectional and quantitative approach. The instruments included the Chronic Disease Self-Efficacy Scale, Stroke Impact Scale, Resilience Scale, and Fatigue Impact Scale. Structural equation modeling (SEM) was performed to analyze the data. A total of 63 patients with stroke (39 male and 24 female) were recruited form a medical university hospital. The results showed that patients' illness representation had a significantly effect on self-efficacy for managing disease. In addition, SEM analysis demonstrated that self-efficacy, resilience and stroke impact influenced fatigue, explaining 20.6% of the variance in fatigue. It was concluded that to improve patient fatigue, we believe it is imperative to design interventions that improve patients' self-efficacy, promote patients' resilience, and better function.
