Illness perceptions in coronary heart disease. Sociodemographic, illness-related, and psychosocial correlates

Effect of health anxiety on disease perception and treatment compliance in elderly patients during the COVID-19 pandemic in Turkey

PURPOSE

This study aimed to determine the effect of health anxiety experienced by elderly individuals during the coronavirus disease 2019 (COVID-19) pandemic on their disease perception and treatment compliance.

DESIGN AND METHODS

This was a descriptive, cross-sectional study conducted between November 2020 and March 2021. The research data was collected using the Patient Information Form, Health Anxiety Scale (HAS), Disease Perception Scale-Short Form (DPS-SF) and Turkish Modified Morisky Treatment Compliance Scale (MMTCS).

RESULTS

Of the 401 study participants, 63.1% were in the 65-69 years age group. The mean HAS, DPS-SF and MMTCS motivation and knowledge level sub-dimension scores of the participants were 18.73 ± 8.87, 54.24 ± 9.98, 1.28 ± 0.74 and 2.04 ± 0.92, respectively.

CONCLUSION

The results of this study showed that the health anxiety and disease perception scores were high among elderly individuals during the COVID-19 pandemic, which hindered their treatment compliance.

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.

Subjective theories of illness in fibroid and endometriosis patients: Similarities, differences, and influencing factors

Introduction:

The aim of this study was to compare the subjective theories of illness in patients with fibroids and patients with endometriosis, and to identify potential factors influencing them.

Methodology:

Participating patients were recruited via three specialized centers for fibroids and endometriosis. To assess their subjective theories concerning the cause of their illness, we used a questionnaire based on the revised Illness Perceptions Questionnaire (IPQ-R). We also gathered and evaluated data relating to sociodemographic factors and psychological distress or possible anxieties using the Kessler Psychological Distress Scale (K10) and the Generalised Anxiety Disorder Assessment (GAD-7).

Results:

We were able to analyze data from 201 patients with fibroids and 212 patients with endometriosis. About 94.4% of the patients had one or more subjective theories concerning the cause of their illness. Both groups perceived “stress or worry” to be the most probable cause of their illness. Compared to endometriosis patients, patients with fibroids were more likely to assume “aging” and “heredity” as the cause of their illness. Endometriosis patients, on the other hand, were more likely to choose theories pertaining to the “environmental influences and immune system” category. The patients’ age, formal education, and conspicuous score values in the K10 or GAD-7 questionnaire proved to be important factors influencing their beliefs about the cause of illness.

Conclusion:

Patients perceive stress and psychological strain as possible causes for their illness. It might be beneficial to take this information into account in conversations between doctors and patients and when drawing up psychosomatic-gynecological treatment plans.

Illness Perception After Heart Valve Surgery: Differences Among Men and Women

BACKGROUND

Illness perception is composed of thoughts, ideas, and beliefs about illness, and a negative illness perception is known to be associated with poor outcomes. Among men and women, clinical outcomes after heart valve surgery are known to differ, but knowledge about differences in illness perception is sparse.

OBJECTIVES

The aim of this study is to describe the differences in illness perception among men and women after open heart valve surgery and to identify sociodemographic and clinical characteristics associated with worse illness perception in men and women.

METHODS

In a national cross-sectional study combined with register-based clinical and sociodemographic information, data on illness perception were collected with the Brief Illness Perception Questionnaire. Worse illness perception was defined as the worst quartile of each item of the Brief Illness Perception Questionnaire. Multiple logistic regression analyses were conducted to explore characteristics associated with worse illness perception.

RESULTS

Of 1084 eligible patients, 32% (n = 349) completed the questionnaire (67% men; mean age, 68 years). Compared with men, women reported significantly worse scores of illness perception in 6 of 8 items. Furthermore, being female, age, length of stay, and comorbidity were associated with worse illness perception (worse quartile of scores). Age, higher educational level, and comorbidity were found to be associated with worse illness perception for men and length of stay for women.

CONCLUSION

After open heart valve surgery, illness perception differs among men and women, with women having worse illness perception. Among the total population, being female, age, a longer length of stay, and comorbidity were also associated with worse illness perception.

From illness perceptions to illness reality? Perceived consequences and emotional representations relate to handicap in patients with vertigo and dizziness

OBJECTIVE

Vertigo and dizziness (VD) are frequent symptoms that can occur due to various structural pathologies or due to functional impairment. Independent of their aetiology, the symptoms are often associated with physical and psychological burden which manifests in severe handicap in more than half of the patients. It is suggested that illness perceptions, the patients' cognitive and emotional concept of their disease, most likely impact the degree of handicap. For patients with VD, however, this relation of illness perceptions and handicap is so far not well understood. This study aimed to investigate the relation of illness perceptions and handicap for patients with VD.

METHODS

In a cross-sectional study design, n = 419 patients with VD were examined (53.7% female, age 53.5 ± 15.5 years). Participants underwent neurological and psychiatric examinations as well as a comprehensive assessment using self-report questionnaires.

RESULTS

Illness perceptions, specifically perceived consequences and emotional representations showed a moderate correlation with VD related handicap (r(419) = 0.62, p < .001). Our regression model including symptom severity, psychiatric comorbidity, and aspects of cognitive and emotional illness perceptions accounted for 52% of the variance in VD related handicap. In a moderation analysis, this relation did not differ significantly in patients with functional VD symptoms.

CONCLUSION

Findings of the present study provide evidence for the relevance of illness perceptions to handicap in patients with VD symptoms.

Gender Differences in Psycho-Social-Spiritual Healing

Background: Many individuals exhibit significant distress in response to serious and/or life-limiting illness. However, there are others who make life-transforming changes, which involve healing experiences in the psychological, social, and spiritual domains of life regardless of illness outcome. The aim of the present study is to determine if there are any differences in psycho-social-spiritual healing between genders.

Materials and Methods: The NIH Healing Experiences in All Life Stressors (NIH-HEALS), a 35-item measure of psycho-social-spiritual healing, is composed of three factors: Connection, Reflection & Introspection, and Trust & Acceptance. NIH-HEALS and a demographic questionnaire were administered to 193 patients with serious and/or life-limiting illness at the National Institutes of Health Clinical Center.

Results: In response to NIH-HEALS, men and women significantly differed on the Reflection & Introspection factor. Women reported increased enjoyment of mind–body practices (p < 0.001), compassion (p = 0.005), gratitude (p = 0.014), and a desire to be more positive (p = 0.044) compared to men. Men rated their pain levels (p = 0.035) and severity of illness (p = 0.016) higher and their overall level of health (p = 0.010) poorer compared to women. Women's responses to items regarding compassion (r_s = 0.37, p < 0.001) and gratitude (r_s = 0.24, p = 0.015) correlated positively with better overall health ratings.

Conclusion: Men and women show some differences in their self-reported psycho-social-spiritual healing, which may have implications when designing interventions aimed at promoting a healing experience in the context of serious and life-limiting illness.

The perception of the illness and the self-efficacy in the management of emotions in cardiac patients

Cardiac rehabilitation is the sum of psychological, physical and social treatments that are offered to cardiac patients to maintain or regain an active position in society. This study wants to evaluate changes in the perception of the illness and in the self-efficacy of the management of positive and negative emotions in patients who went through cardiac rehabilitation. Sixty-seven patients (20 females, 47 males) were selected within the cardiac rehabilitation unit in the Hospital of Cittadella (Italy). Illness Perception Questionnaire - revised version and the Scale for the self-efficacy of the management of positive and negative emotions were submitted at the beginning and at the end of the rehabilitation program. One-way analyses-of-variance were performed to evaluate different answers in questionnaires between pre- and post-evaluation, and to explore gender differences. A significant change was found in the perception of duration of illness, perceived as permanent and longer after the cardiac rehabilitation program. Furthermore, at the end of the cardiac rehabilitation program men perceived the illness more chronic than women, even if they are less worried and anxious. Intensive cardiac rehabilitation has a great emotional impact on cardiac patients, influencing their perception and management of the illness. Working on emotions, through psychological groups, helps patients change their beliefs by offering them a different perspective to approach the illness.

Exploration of illness perception among patients with mental illness in a multi-ethnic Asian sample

Illness perceptions are beliefs that patients have about their illness. These beliefs play an important role in influencing their behaviour and outcomes. This study examined the factor structure and correlates of the Illness Perception Questionnaire Mental Health (IPQ-MH) among patients with mental illness in a multi-ethnic Asian sample. 400 participants with schizophrenia and other psychotic disorders, mood or anxiety disorder were recruited from a tertiary psychiatric institution and administered the IPQ-MH. Data on sociodemographic variables were also collected. A multi-factor structure was identified for the Identity, Structure and Cause subscale of the IPQ-MH. Age was consistently associated with a positive perception of illness across all three disorders; women had a more positive perception of schizophrenia and other psychotic disorders as compared to men while those of Indian ethnicity had a more negative perception of their mood disorder as compared to those of Chinese ethnicity. Those with lower education had a poorer understanding of their illness among those with mood disorder, and a poorer understanding of their illness and the effectiveness of treatment among those with anxiety disorder. The study identified specific groups which can be targeted through tailored and culturally relevant psychoeducational interventions to enhance their understanding and perception of mental illness.

Illness perception and cardiovascular health behaviour among persons with ischemic heart disease in Indonesia

OBJECTIVE

A study was conducted to explore the level of illness perception, the level of cardiovascular health behaviour and the relationship between illness perception and cardiovascular health behaviour among persons with ischemic heart disease (IHD) in a community setting.

METHOD

The participants comprised 235 persons with IHD. The instruments used were as follows: 1) Demographic Data and Health Information, 2) The Brief Illness Perception Questionnaire (Brief IPQ), 3) The Open-ended Questionnaire (OEQ), and 4) The Modified Cardiac Health Behaviour Scale (MCHBS). Findings from the OEQ are used to assess in-depth illness perception and to extend the information obtained from the Brief IPQ. The design of the study was descriptive correlational. The data were analysed using descriptive statistics to present the demographic data and health information. Inferential statistics was used to resolve the relationship between illness perception and cardiovascular health behaviour by using Pearson's Product Moment Correlation.

RESULT

The mean score of illness perception was at a moderate level (M = 43.65, SD = 3.93), whereas the mean score of cardiovascular health behaviour was at a high level (M = 80.29, SD = 5.42). A significant positive relationship existed between illness perception and cardiovascular health behaviour among persons with IHD (r = 0.38, P < 0.01).

CONCLUSION

Persons with higher illness perception showed a positive correlation with higher cardiovascular health behaviour at a significant level of 0.01. Results provided important information for nurses to develop an intervention program to promoting appropriate illness perception and cardiovascular health behaviour among persons with IHD.

Modifiable correlates of illness perceptions in adults with chronic somatic conditions: A systematic review

When individuals become ill, they want to understand and give meaning to their illness. The interpretation of this illness experience, or illness perception, is influenced by a range of individual, contextual, and cultural factors. Some of these factors may be modifiable by nursing interventions. The purpose of this systematic review was to investigate which modifiable factors were correlated with illness perceptions across studies of adults with different chronic somatic diseases. Using search terms tailored to each of four electronic databases, studies retrieved were reviewed by two independent evaluators, and each relevant article was assessed for methodological quality. Results were standardized by calculating correlation coefficients. Fifteen papers on illness perceptions in a variety of chronic diseases met the inclusion criteria. All used standardized measures of illness perceptions. We identified five groups of modifiable correlates of illness perceptions: illness-related factors, psychosocial factors, medication beliefs, information provision and satisfaction with information received, and quality of care. Our findings add to the knowledge of modifiable factors correlated with illness perceptions, including the importance of illness-related factors and psychosocial factors such as anxiety and depression. Knowledge of these correlates can facilitate understanding of patients' illness perceptions and might be useful in tailoring patient education programs.

Illness perception in patients with coronary artery disease: A systematic review

The aim of this study was to conduct a systematic review that investigates the differences in illness perception with age and gender in patients diagnosed with coronary artery disease. Previous studies show some discrepancies regarding the influence of age and gender on the specific dimensions of coronary artery disease patients' illness perception. A systematic review using a narrative synthesis process included preliminary synthesis, exploration of relationships and assessment of the robustness of the synthesis and findings was conducted. Search terms were used to identify research studies published between 1996 and December 2014 across four key databases: CINAHL, Medline, PsycINFO and Web of Science. A total of 14 studies met the inclusion criteria of the review. The review found that men had a stronger perception that their own behaviour had caused their illness than women. In addition, older patients had lower perceptions of the consequences and chronicity of their illness. This analysis concludes that some dimensions of illness perception vary according to age and gender of patients with coronary artery disease. These differences should be taken into consideration, particularly when providing health education and cardiac rehabilitation.

Patients' beliefs about the causes of heart disease: relationships with risk factors, sex and socio-economic status

BACKGROUND

Patients' beliefs about the causes of their heart disease (causal attributions) are important to effective medical communication, psychological adaptation, and adherence to advice. We assessed the extent to which causal attributions relate to risk factors, sex and socio-economic status in men and women diagnosed with acute coronary syndrome.

DESIGN

We conducted an interview and questionnaire study of 171 acute coronary syndrome patients assessed within 5 days of admission to three hospitals in the London area.

METHOD

Patients rated beliefs in the role of 16 factors in causing their heart disease. Associations between attributions and risk factors were assessed, and differences in beliefs by sex and socio-economic status (defined by educational attainment) analysed.

RESULTS

The most common attributions were to stress, smoking, high blood pressure, chance or bad luck, and heredity. Attributions were strongly associated with risk factors: 90% of smokers attributed heart disease to smoking, compared with 0% never smokers; 90.4% of hypertensives attributed heart disease to high blood pressure, 72.2% of patients with a positive family history to heredity, 85% of obese patients to being overweight, and 49% of sedentary patients to lack of exercise. Attributions to stress were related both to current mood and reports of recent life stress. There were few sex differences, but higher socio-economic status patients were more likely to attribute heart disease to heredity and genetic factors.

CONCLUSIONS

Causal beliefs about heart disease are strongly associated with risk factors. Effective communication about modifiable risk factors may influence causal beliefs and stimulate lifestyle change, thereby promoting secondary prevention.

Perceiving one's heart condition to be cured following hospitalization for acute coronary syndromes: Implications for patient-provider communication

OBJECTIVE

We examined the proportion of patients perceiving their heart condition to be cured following hospitalization for ACS and identified characteristics associated with these perceptions.

METHODS

We conducted a prospective cohort study of adults hospitalized with ACS (N=396). Patient interviews during hospitalization and one week post-discharge provided demographic and psychosocial characteristics. Medical records provided clinical characteristics. At one week, patients who rated "My heart condition is cured" as "definitely true" or "mostly true" were considered to perceive their heart condition cured.

RESULTS

Participants were aged 60.7 (SD:11.0) years, 26.5% female, and 89.0% non-Hispanic white; 16.7% had unstable angina, 59.6% NSTEMI, and 23.7% STEMI. One week post-discharge, 30.3% perceived their heart condition to be cured. Characteristics associated with cure perceptions were older age (OR=2.2; 95% CI: 1.2-4.0 for ≥65 years vs <55 years), male sex (OR=2.4; 95%CI: 1.3-4.2), history of hypertension (OR=1.8; 95%CI: 1.1-3.1), history of stroke (OR=4.2; 95%CI: 1.1-16.7), no history of CHD (OR=2.8; 95%CI: 1.6-4.9), and receipt of CABG during hospitalization (OR=4.8, 95%CI: 1.9-12.0 vs medical management).

CONCLUSION

One week post-discharge, 3 in 10 patients perceived their heart condition to be cured.

PRACTICE IMPLICATIONS

Conversations with patients should frame ACS as a chronic disease and dispel cure perceptions.

Chronic Diseases in North-West Tanzania and Southern Uganda. Public Perceptions of Terminologies, Aetiologies, Symptoms and Preferred Management

Background

Research has shown that health system utilization is low for chronic diseases (CDs) other than HIV. We describe the knowledge and perceptions of CDs identified from rural and urban communities in north-west Tanzania and southern Uganda.

Methods

Data were collected through a quantitative population survey, a quantitative health facility survey and focus group discussions (FGDs) and in-depth interviews (IDIs) in subgroups of population survey participants. The main focus of this paper is the findings from the FGDs and IDIs.

Results

We conducted 24 FGDs, involving approximately 180 adult participants and IDIs with 116 participants (≥18 years). CDs studied included: asthma/chronic obstructive lung disease (COPD), diabetes, epilepsy, hypertension, cardiac failure and HIV- related disease. The understanding of most chronic conditions involved a combination of biomedical information, gleaned from health facility visits, local people who had suffered from a complaint or knew others who had and beliefs drawn from information shared in the community. The biomedical contribution shows some understanding of the aetiology of a condition and the management of that condition. However, local beliefs for certain conditions (such as epilepsy) suggest that biomedical treatment may be futile and therefore work counter to biomedical prescriptions for management.

Conclusion

Current perceptions of selected CDs may represent a barrier that prevents people from adopting efficacious health and treatment seeking behaviours. Interventions to improve this situation must include efforts to improve the quality of existing health services, so that people can access relevant, reliable and trustworthy services.

Illness perceptions in patients with somatoform disorders: Examining the role of comorbidity

We examined the role of comorbidity in models that use the illness perceptions of patients with somatoform disorders to explain their outcomes. A total of 138 primary care patients with somatoform disorders completed the Patient Health Questionnaire and Brief Illness Perception Questionnaire and rated their general health status. Medical comorbidity was rated by the general practitioner. Patients’ illness perceptions were consistently related to their outcomes independent of medical and psychological comorbidity in our models. At the same time, inclusion of comorbidity enhanced our models, revealing differences in the relevance of the specific comorbidity depending on the outcome measure.

The effect of a telephone follow-up intervention on illness perception and lifestyle after myocardial infarction in China: a randomized controlled trial

BACKGROUND

Lifestyle modification is an integral component of cardiac secondary prevention, while it has been confirmed that myocardial infarction (MI) patients' health-related behaviors are heavily influenced by their illness perception.

OBJECTIVES

To evaluate the effect of a telephone follow-up intervention for improving MI patients' illness perception and lifestyle.

DESIGN

A randomized controlled trial, longitudinal research design was employed.

SETTINGS

Cardiac care units in four major general hospitals in Guangzhou, China.

PARTICIPANTS

Inclusion criteria were being diagnosed with an initial acute MI, being able to communicate orally in Mandarin or Cantonese and read in Chinese, and living in Guangzhou. Exclusion criteria were with continuing uncontrolled arrhythmias or heart failure, being illiteracy, or with a history of major psychiatric illness, exercise-induced asthma, uncontrolled diabetes, or evidence of dementia.

METHOD

124 patients admitted with the first acute MI were randomized to receive either routine care or routine care plus a telephone follow-up intervention, which consist of a pre-discharge education and three telephone follow-up instructions. Data were collected before discharge, at the 6th and the 12th week after discharge from hospital, respectively.

RESULTS

At the 6th and the 12th week after discharge, patients in the intervention group had significantly positive perceptions about symptoms of MI (mean difference 3.27, 95% confidence interval 2.48-4.07, p<.001; mean difference 2.12, 95% confidence interval 1.34-2.89, p<.001 respectively) and how long their illness would last (mean difference -0.69, 95% confidence interval -0.91 to -0.47, p<.001; mean difference -0.74, 95% confidence interval -0.96 to -0.51, p<.001 respectively) compared with the control group. The intervention group also had more positive beliefs about the controllability (F=4.23, p=.04) and more improved beliefs about the causes of MI than the control group. Moreover, the intervention improved the patients' nutrition (F=5.16, p=.03) and physical activity at the 12-week follow-up (mean difference 0.37, 95% confidence interval 0.17-0.58, p<.001).

CONCLUSION

This telephone follow-up intervention can result in improved illness perception and lifestyle after MI. It could be incorporated into current hospital treatment regimens for MI to improve patients' quality of life.

Patients' and partners' illness perceptions in screen-detected versus clinically diagnosed type 2 diabetes: partners matter!

BACKGROUND

In type 2 diabetes, educational interventions that target differences between patients' and partners' illness perceptions have been advocated.

OBJECTIVE

To investigate how the route to diagnosis of type 2 diabetes (through screening versus clinical symptoms) affects illness perceptions of patients and their partners.

METHODS

In a cross-sectional study, we enrolled patients aged 40-75 years from general practices in the Netherlands with a new diagnosis of type 2 diabetes (≤3 years), detected by either screening (n = 77) or clinical symptoms (n = 32). Patients and their partners each completed a postal Brief Illness Perception Questionnaire (Brief IPQ), and up-to-date clinical data were obtained from their GP. The Brief IPQ scores of the screening and clinical diagnosis groups were compared for both patients and partners, and multiple variable linear regression models with Brief IPQ scores as outcomes were developed.

RESULTS

The route to diagnosis did not appear to have a strong influence on patients' illness perceptions but did influence illness perceptions of their partners. Partners of patients diagnosed through screening perceived greater consequences for their own life, had a stronger feeling that their patient-partners had control over their diabetes, were more concerned about their partners' diabetes, and believed that their patient-partners experienced more diabetes symptoms, compared with partners of patients who were diagnosed through clinical symptoms.

CONCLUSIONS

The route to diagnosis of type 2 diabetes has a greater impact on the illness perceptions of partners than that of patients. Professionals in diabetes education and treatment should consider these differences in their approach to patient care.

[Journey to what is essentially invisible: pysochosocial aspects of disease]

Physicians may be well equipped for the biological aspects of disease, but not for its psychosocial dimensions, an issue that has been absent in family medicine. The psychosocial aspects of the disease are the factors involved in how patients react to the disease, play a role in the expression of symptoms and disease, and have implications on the lives of patients. Moreover, the biological effects (specific) and psychosocial effects (non-specific) are not simply additive but interactive. Physicians should be aware of this hidden, essentially invisible patient psychosocial morbidity, and must incorporate bio-psychosocial interventions into routine medical care to be more effective. In addition, to consider these aspects in the context of care contributes to the distinctive elements of family medicine.

Purpose in life and reduced risk of myocardial infarction among older U.S. adults with coronary heart disease: a two-year follow-up

This study examined whether purpose in life was associated with myocardial infarction among a sample of older adults with coronary heart disease after adjusting for relevant sociodemographic, behavioral, biological, and psychological factors. Prospective data from the Health and Retirement Study-a nationally representative panel study of American adults over the age of 50-were used. Analyses were conducted on the subset of 1,546 individuals who had coronary heart disease at baseline. Greater baseline purpose in life was associated with lower odds of having a myocardial infarction during the 2-year follow-up period. On a six-point purpose in life measure, each unit increase was associated with a multivariate-adjusted odds ratio of 0.73 for myocardial infarction (95% CI, 0.57-0.93, P = .01). The association remained significant after controlling for coronary heart disease severity, self-rated health, and a comprehensive set of possible confounds. Higher purpose in life may play an important role in protecting against myocardial infarction among older American adults with coronary heart disease.

Illness perception among Chinese patients with acute myocardial infarction

OBJECTIVE

To explore illness perception (IP) and its predictors among Chinese patients with myocardial infarction (MI).

METHODS

The revised Illness Perception Questionnaire (IPQ-R) was used in the present study. A cross-sectional, descriptive design was employed. The study was conducted in four major hospitals in Guangzhou (China) with a sample of 193 MI patients. Pearson's and Spearman's correlation, t test, one-way ANOVA, factor analysis and multiple linear regression were used.

RESULTS

Among the 12 common symptoms of MI, on average only 3.37 were recognized by the subjects. Among the six factors of the cause dimension, "immune factors" received the highest score, followed by "gene and chance", "behavioral factors", "psychological factors", "environmental factors", and "physical factors". Subjects perceived MI as a chronic, cyclic illness with serious consequences that could be controlled through treatment, and believed that they had a negative affective response to MI. Furthermore, the dimensions of patients' IP were correlated, and illness-related factors and socio-demographic factors acted as predictors of IP.

CONCLUSION

The IP of Chinese patients with MI needs to be improved.

PRACTICE IMPLICATIONS

Based on our findings, effective interventions can be designed to promote MI patients' IP to facilitate their coping strategies after an episode of MI.

Self-reported adverse drug events and the role of illness perception and medication beliefs in ambulatory heart failure patients: A cross-sectional survey

BACKGROUND

Identifying patients with heart failure (HF) who are at risk of experiencing symptomatic adverse drug events (ADEs) is important for improving patient care and quality of life. Several demographic and clinical variables have been identified as potential risk factors for ADEs but limited knowledge is available on the impact of HF patients' beliefs and perceptions on their experience of ADEs.

OBJECTIVE

The purpose of the study was to identify the relationship between HF patients' illness perception and medication beliefs and self-reported ADEs.

DESIGN

A cross-sectional survey was performed between November 2008 and March 2009.

SETTINGS

One university medical centre, two regional hospitals and 20 general practitioners in the Netherlands participated in the study.

PARTICIPANTS

495 patients with HF were included.

METHODS

Patients completed the validated Revised Illness Perception Questionnaire (IPQ-R) and the Beliefs about Medication Questionnaire (BMQ) which collected data on their illness perception and medication beliefs. In addition, data on ADEs as experienced in the previous four weeks were collected through an open-ended question and a symptom checklist. Multivariate logistic regression was performed to identify factors associated with these ADEs.

RESULTS

In total, 332 (67%) patients had experienced ADEs in the previous four weeks, of whom 28% reported dry mouth, 27% dizziness and 19% itchiness as the most prevalent. In the adjusted multivariate analysis, disease-related symptoms (illness identity) (OR for 1-5 symptoms 3.57; 95% CI 2.22-5.75, OR for >5 symptoms 7.37; 95% CI 3.44-15.8), and general beliefs about medication overuse (OR 1.07; 95% CI 1.01-1.13) were independently associated with experiencing ADEs, whereas none of the demographic or clinical factors were significant.

CONCLUSIONS

HF patients who perceive a high number of disease symptoms and have negative medication beliefs are at higher risk of experiencing self-reported ADEs. We suggest that future studies and interventions to improve ADE management should focus on negative medication beliefs and assisting patients in differentiating disease symptoms from ADEs.

Myocardial infarction: a turning point in meaning in life over time

Finding meaning in illness appears to give individuals purpose in life, which may motivate them to maintain a healthy lifestyle. Research to date has mainly used cross-sectional designs in the acute phase of recovery. This article describes a longitudinal exploratory study which explored patients' search for meaning in life across the first 5 years following myocardial infarction (MI). Interviews were conducted between 2000 and 2007 on patients with first MI (n=70; mean=61.9 years; SD=12.1). The qualitative data underwent thematic analysis guided by the analysis framework of Burnard (1991). Finding meaning appeared to increase patients' awareness of their current holistic state of life, and to provide impetus for making lifestyle changes. In the immediate aftermath of MI, patients restructured and re-evaluated their attitudes towards self, life, religious beliefs and others. However, from the third year onwards, as time passed patients lapsed in their behaviour, tending to become non-compliant with treatment and less aware or concerned about the risk of another heart attack. Further education on the spiritual dimension in care may guide nurses and health professionals in order to promote patients' rehabilitation process and persevere with a long-term healthy lifestyle. Further longitudinal comparative research with mixed method approach on various groups of patients is recommended to support these findings.

Causal attributions among patients undergoing coronary artery bypass surgery: gender aspects and relation to depressive symptomatology

Causal attributions made by patients for their coronary heart disease may contribute to gender differences in emotional adjustment. The purpose of this study was to determine gender differences in causal attributions and to analyze the associations between causal attributions and depressive symptomatology in patients undergoing coronary artery bypass graft (CABG) surgery. Nine hundred and seventy-nine patients (mean age 66.8 years, 19.9% women) completed a modified version of the Illness Perception Questionnaire (IPQ) and the depression module of the Patient Health Questionnaire (PHQ-9) 1-3 days before CABG-surgery and 1 year after surgery. Men were more likely to name their health behavior (men: 40.2%, women: 26.9%, P < .001) as a cause of disease, whereas women were more likely to cite destiny (women: 34.7%, men: 25.7%, P = .012). Regression analyses showed cross-sectional and longitudinal associations of attributions with depressive symptomatology which were independent of gender, sociodemographic and clinical variables. Attribution to personality and stress were associated with an increase in depressive symptomatology. Causal attributions may present a valuable approach for identifying patients at risk for depression and the implementation of targeted interventions.

Awareness of stroke symptomatology and cardiovascular risk factors amongst stroke survivors

BACKGROUND

Effective treatments exist for the acute management and prevention of stroke, but their uptake depends upon public awareness of stroke symptoms and cardiovascular risk factors. We evaluated the extent of both types of knowledge amongst high-risk individuals. Furthermore, we determined whether knowledge of risk factors, and appreciation of personal risk, influences risk avoidance behaviour.

METHODS

A validated comprehensive questionnaire assessing knowledge of stroke symptoms and personal risk factors was completed by stroke survivors across the United Kingdom.

RESULTS

Questionnaires were completed by 622 stroke survivors (age range, 18-91 yrs; mean, 55.4 yrs). Recall of all 3 cardinal stroke symptoms (face, arm or leg, and speech disturbance) was made by only 14% of respondents, with 34% citing none of these symptoms. Knowledge of any established stroke risk factor was cited by 55% of respondents, with the remainder believing that stroke occurs because of chance. Similarly, 45% did not acknowledge that having had a previous stroke predisposed to future cardiovascular disease. Respondents recognising their own personal future risk were more likely to consume less alcohol (P < .0001) and salt (P < .005) and to eat more fruits and vegetables (P < .02).

CONCLUSIONS

Knowledge of stroke symptoms and cardiovascular risk factors is poor amongst high-risk stroke patients. However, an awareness of personal risk of future stroke increased the likelihood of adopting secondary prevention behaviours after stroke. Our results have important implications for the prevention of secondary vascular disease in stroke patients and the effects of public health campaigns on high-risk stroke groups.

[Illness perception in chronic obstructive pulmonary disease]

INTRODUCTION

The aim of the study was to investigate illness perception in patients with chronic obstructive pulmonary disease (COPD), and to explore its relation to socio-demographic and illness/treatment-related characteristics.

MATERIAL AND METHODS

44 consecutive COPD patients answered the general questionnaire (which identified data on gender, age, education, economic status, employment, personal estimate of family relations quality) and IPQ-R (which evaluates the illness perception components). The data were statistically processed using T-test, Mann-Whitney U-test, one way anova, and correlation analysis.

RESULTS

COPD patients perceived their illness predominantly negatively. The markers of negative illness perception were female gender: older age, medium economic status, being employed, and high number of hospital treatments. The self report of good family relations was associated with both positive (strong belief in personal control) and negative illness perception (belief in serious consequences). Believing that external causes were predominantly responsible for the illness onset was related to the positive illness representation and to a lower education level.

CONCLUSION

Illness perception in COPD patients is negative and associated with certain socio-demographic and illness/treatment-related characteristics; this may have implications for detecting and modifying negative perception patterns in patients at risk.

Poor use of cardiac rehabilitation among older adults: a self-regulatory model for tailored interventions

BACKGROUND

A greater number of older adults now live with coronary heart disease (CHD). This poses a significant public health problem, because older adults are at high risk for CHD-related mortality and morbidity. Overwhelming data support the benefits of cardiac rehabilitation for secondary prevention, yet only a small portion of eligible older adults receive it.

METHODS AND RESULTS

Whereas many studies examined factors that affect the use of cardiac rehabilitation among older adults, few interventions aimed to improve their cardiac rehabilitation participation rates. A substantial body of evidence indicates that an individual's illness perceptions play a pivotal role in health behavior, and may be a promising target for intervention. Drawing from the theoretic and empiric findings of others, a self-regulatory model is proposed that explicates how CHD perceptions of older adults may influence participation in cardiac rehabilitation.

CONCLUSION

The model may provide a useful guide for the development of effective interventions tailored to older adults.

Concept analysis of risk in relation to coronary heart disease among Filipino-Americans

PURPOSE

To analyze the concept of risk in relation to coronary heart disease (CHD) among Filipino-Americans (FAs) and provide a new definition of risk.

SOURCE

Published literature.

CONCLUSION

This concept analysis provided a new meaning of risk in relation to CHD among FAs and shed light on further understanding of risk. Risk has been laced with negativity in health care, but based on the current literature, risk can be conceptualized in a positive perspective, especially in the area of chronic health disease such as CHD. However, further research is needed in the conceptualization of risk related to CHD for consistency, adequacy, and meaning.

Perceptions of coronary heart disease risk in African American women with type 2 diabetes: a qualitative study

PURPOSE

The purpose of this study was to explore the perceptions of coronary heart disease (CHD) risk in a group of southern African American women with type 2 diabetes (T2DM).

METHODS

Semistructured interviews were conducted in participants' homes or setting of choice. The interviews were conducted with 6 participants from a larger study of 48 women who were stratified into levels of low, medium, and high perception of CHD risk, with 2 participants in each group. The interviews were analyzed using NVivo software; both investigators recoded and analyzed the data.

RESULTS

African American women with T2DM do not believe they are at risk for CHD unless they are told specifically by their primary health care provider that they have heart disease. The African American women in the study expressed that managing their diabetes to prevent heart disease can be overwhelming. Participants identified faith beliefs called not claiming the illness as a reason they did not perceive themselves at risk for CHD.

CONCLUSIONS

Not claiming an illness may influence health and preventive behaviors. Many African American women with T2DM may not claim their illness. Diabetes educators should acknowledge and address women's beliefs to create an appropriate plan of care.

Are illness perceptions about coronary artery disease predictive of depression and quality of life outcomes?

OBJECTIVE

Depression occurs commonly in coronary artery disease (CAD) and is associated with substantial disability. Modifiable cognitive determinants of depression in this population have not been identified. We investigated the impact of potentially modifiable illness beliefs about CAD on depressive symptomatology. We also examined the association between these beliefs and health-related quality of life (HRQOL) and socio-demographic variations in illness beliefs.

METHODS

A prospective study of 193 recently hospitalized CAD patients was conducted. Data were collected from medical records and by self-report 3 and 9 months post-discharge. Socio-demographic differences were analysed with independent sample t-tests. Predictive models were tested in a series of hierarchical linear regression equations that controlled for known clinical, psychosocial, and demographic correlates of outcome.

RESULTS

Negative illness beliefs, particularly those associated with the consequences of CAD, were significantly predictive of higher levels of depressive symptomatology at 3 and 9 months. Positive illness perceptions were significantly associated with better HRQOL outcomes. Older and less socially advantaged patients demonstrated more negative illness beliefs.

CONCLUSIONS

Illness beliefs are significantly associated with depressive symptomatology and HRQOL in CAD patients. These beliefs can be easily identified and constitute a meaningful and clinically accessible avenue for improving psychological morbidity and HRQOL in CAD patients. Older and more socially vulnerable patients may require heightened monitoring of their illness beliefs. Research needs to translate these and other predictive findings into interventions.

Illness beliefs about heart disease and adherence to secondary prevention regimens

OBJECTIVE

We investigated illness beliefs of recently hospitalized patients with coronary artery disease (CAD) and the prospective association between these beliefs and adherence to secondary prevention behaviors. Causal attributions of CAD and their concordance with actual patient risk profiles were also examined.

METHOD

A prospective study of 193 patients was conducted. Data were collected by self-report and from medical records at 3, 6, and 9 months after discharge. Baseline depression was assessed by structured clinical interview. The association between illness beliefs and adherence was tested with hierarchical linear regression controlling for clinical and demographic confounders.

RESULTS

Most participants perceived high personal and treatment control and believed CAD to be chronic in duration with severe consequences. A relatively low number of symptoms were endorsed as being part of CAD. Heredity was considered the single most important and most commonly perceived cause of CAD. Smoking, alcohol, emotional state, and heredity were significantly more likely to be endorsed as causal factors by respondents with these risk profiles. In multivariate analysis, illness beliefs contributed an additional 6% of the total variance explained by the model (p = .02). Perceptions of more serious consequences predicted better adherence (p = .03). Social desirability was the best single predictor of adherence.

CONCLUSION

Patient perceptions of risk factors were largely consistent with actual risk factors. Despite modest effect sizes, illness beliefs do contribute to our understanding of adherence to secondary prevention behavior. Interventions aimed at modifying these beliefs, particularly those related to the consequences of CAD, may improve patient outcomes.

Fear of recurrence and beliefs about preventing recurrence in persons who have suffered a stroke

OBJECTIVES

The aim of this study was to investigate fear of recurrent stroke and beliefs about its causes and prevention.

METHODS

Eighty-nine patients participated 1 month following stroke and 81 were followed up at 9 months. Interviews addressed fears and beliefs about stroke, causes, recurrence and prevention by using closed and open-ended questions. Responses were subject to quantitative and qualitative analysis, respectively.

RESULTS

Fear of recurrence was common. Profound disability was a particularly feared outcome. Participants were knowledgeable about causes. However, causal controllability ratings were low. Some reported concern about preventative strategies (e.g., difficulty stopping smoking). Many reported idiosyncratic beliefs (e.g., avoiding overexertion) or fatalistic ideas about strokes (e.g., 'nothing' can prevent them). Similar quantitative results were obtained at follow-up.

CONCLUSIONS

Many patients fear stroke recurrence. They lack a sense of control over causes and have fears associated with idiosyncratic and fatalistic beliefs. There is a need to elicit and address individuals' own fears and beliefs about stroke before providing evidence-based secondary prevention recommendations.

Illness perceptions predict attendance at cardiac rehabilitation following acute myocardial infarction: a systematic review with meta-analysis

OBJECTIVE

Early reports indicated that the illness perceptions of patients following acute myocardial infarction (AMI) predict attendance at cardiac rehabilitation. However, null findings have subsequently been reported, and there is variation between studies in terms of which illness perception constructs predict attendance. The aim of this meta-analysis was to examine whether illness perceptions really predict attendance at cardiac rehabilitation and to examine factors that moderate this relationship.

METHODS

The strategy and procedures recommended by Hunter and Schmidt [Hunter JE, Schmidt FL. Methods of meta-analysis: correcting error and bias in research findings. Thousand Oaks (CA): Sage, 2004] were followed. Based on a systematic literature search, eight studies (N=906 patients) that examined the relationship between illness perceptions and attendance at cardiac rehabilitation were included.

RESULTS

Four illness perception constructs significantly predicted attendance at cardiac rehabilitation: patients with more positive identity (r=.123), cure/control (r=.111), consequences (r=.081), and coherence (r=-.160) beliefs were more likely to attend cardiac rehabilitation. For all relationships, except that between cure/control beliefs and rehabilitation attendance, there was significant heterogeneity, which was attributable to two studies: one that assessed illness perceptions after leaving the hospital yielded higher effect size estimates, whereas another that involved an intervention yielded effect size estimates in the direction opposite to those of most other studies. The exclusion of these studies resulted in largely unchanged, but homogeneous, effect size estimates.

CONCLUSION

Illness perceptions of AMI patients predict attendance at cardiac rehabilitation, although the effect sizes are small and often heterogeneous. AMI patients who view their condition as controllable, as symptomatic, and with severe consequences, and who feel that they understand their condition are more likely to attend.

Sociodemographic, Disease Status, and Illness Perceptions Predictors of Global Self-ratings of Health and Quality of Life Among those with Coronary Heart Disease – One Year Follow-up Study

This one-year follow-up study (n = 130 at baseline, n =2745 at follow-up, aged 45-74 years) examined the relationship of patients' perceptions of coronary heart disease (CHD) and illness-related factors with global health status and global quality of life (QOL) ratings. The independent variables were CHD history (myocardial infarction, revascularisation), CHD severity (use of nitrates, CHD risk factors and co-morbidities) and illness perceptions. In multivariate regression analysis, CHD history and severity explained 13% of variance in global health status and 8% in global QOL ratings at the baseline. Illness perceptions increased the share of explained variance by 18% and 16% respectively. In the follow-up, illness perceptions explained a significant but modest share of variance in change in health status and QOL when baseline health status and QOL and CHD severity were adjusted for more symptoms being attributed to CHD, severe perceived consequences of CHD, as well as a weak belief in the controllability of CHD were related to poor global health status and QOL ratings. In structural path models associations of CHD severity factors were mediated by illness perceptions. The association of disease severity with dependent variables was weaker after controlling for illness perceptions. Cognitive representations of CHD contribute to both global health status and QOL ratings and they also mediate the associations between CHD severity and well-being. No gender differences were found in associations of illness perceptions with health status or QOL ratings.
