Can illness beliefs, from the common-sense model, prospectively predict adherence to self-management behaviours? A systematic review and meta-analysis

Illness perception: A bibliometric study

Illness perception is a crucial area of study that has seen significant growth and development over the years. This study conducts a comprehensive bibliometric and network analysis of illness perception research, capturing its evolution from 1975 to 2023. Utilizing 1813 publications from the Scopus database, authored by 5428 researchers, we identify key scholars and influential articles in the field. Our analysis includes various bibliometric networks such as citation, co-citation, collaboration, and keyword co-occurrence networks, along with the presentation of intellectual structure maps. Major research areas include the role of illness perception in mental health conditions like depression, coping mechanisms, quality of life, and chronic illnesses like diabetes, as well as the influence of lay beliefs on health behaviors, and the impact of illness beliefs on conditions like Myocardial Infarction and stroke. The results show a growing academic interest in understanding how illness perceptions shape healthcare outcomes and behaviors.

Self-management intervention improves patient adherence to swallowing exercises during radiation for head and neck cancer

BACKGROUND

While preventive swallowing exercises reduce the risk of radiation-associated dysphagia in patients with head and neck cancer, strategies are needed to improve patient adherence.

METHODS

Before radiation, all participants were taught preventive swallowing exercises and randomized to either an adherence intervention or enhanced usual care. During radiation, all participants met twice with a speech pathologist for swallowing assessment and reinforcement of exercises. Intervention participants met weekly with a counselor in-person or by phone. At 6-week post-radiation follow-up, all participants completed a follow-up assessment of self-reported adherence, which was then corroborated with medical record documentation.

RESULTS

Newly diagnosed pharyngeal and laryngeal cancer patients without distant metastases were randomized (n = 265; 135 to intervention, and 130 to usual care). Intervention participants were more likely to adhere to exercises during radiation compared to the control group (p < 0.0001).

CONCLUSION

The weekly in-person adherence intervention program significantly increased patient's adherence to preventive swallowing exercises during radiation.

Adherence to Parkinson's disease medication: A case study to illustrate reasons for non-adherence, implications for practice and engaging under-represented participants in research

Parkinson's disease (PD) is a progressive neurodegenerative disease which primarily presents with the core symptoms of rigidity, postural instability, tremor, and bradykinesia. Non-adherence to prescribed PD treatments can have significant ramifications, such as poor symptom control and greater disease burden. Reasons for poor adherence are multifaceted, particularly when medication regimens are complex and often based on perceptual and practical barriers. Additionally, engaging fully non-adherent patients in research is challenging since they may have dropped out of service provision, yet their contribution is vital to fully understand the rationale for non-adherence. This paper aims to present a case study on the perspectives of one person with PD, a participant in a previously published qualitative study investigating the barriers and facilitators to medication adherence in PD. In this paper, the participant's diagnostic journey is described, and experiences of medical consultations are summarised to explain their reasons for not adhering to any of the standard UK PD treatments prescribed. The participant's preferences for using Vitamin B1 (thiamine) injections to manage the symptoms are reported and the rationale for doing so is discussed. We consider the case through the lens of a behavioural science approach, drawing on health psychology theory, the Theoretical Domains Framework (TDF), to inform the review and the practical challenges faced when analysing the data for this participant. Implications for pharmacy practice, in particular, are also put forward with view to ensuring that patients such as Mr. Wilkinson are provided with the opportunity to discuss treatment choices and self-management of long-term conditions such as PD. We also discuss the importance of reaching under-represented members of the population in medication adherence research, which embraces the principles of equality, diversity, and inclusion in research.

Behavioral Science: Enhancing Our Approach to the Development of Effective Additional Risk Minimization Strategies

Additional risk minimization strategies may be required to assure a positive benefit-risk balance for some therapeutic products associated with serious adverse drug reactions/risks of use, without which these products may be otherwise unavailable to patients. The goals of risk minimization strategies are often fundamentally to influence the behavior of healthcare professionals (HCPs) and/or patients and can include appropriate patient selection, provision of education and counselling, appropriate medication use, adverse drug reaction monitoring, and adoption of other elements to assure safe use, such as pregnancy prevention. Current approaches to additional risk minimization strategy development rely heavily on information provision, without full consideration of the contextual factors and multi-level influences on patient and HCP behaviors that impact adoption and long-term adherence to these interventions. Application of evidence-based behavioral science methods are urgently needed to improve the quality and effectiveness of these strategies. Evidence from the fields of adherence, health promotion, and drug utilization research underscores the value and necessity for using established behavioral science frameworks and methods if we are to achieve clinical safety goals for patients. The current paper aims to enhance additional risk minimization strategy development and effectiveness by considering how a behavioral science approach can be applied, drawing from evidence in understanding of engagement with pharmaceutical medicines as well as wider public health interventions for patients and HCPs.

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.

Preliminary Validation of the Revised Illness Perception Questionnaire for Patients with Nasopharyngeal Carcinoma in China

Nasopharyngeal carcinoma is a common and highly malignant cancer in southern China. It is important to accurately assess the illness perception of nasopharyngeal carcinoma according to the common-sense model of self-regulation. The purpose was to validate the Chinese version of the Revised Illness Perception Questionnaire for patients with Nasopharyngeal carcinoma. A cross-sectional survey of 631 patients with Nasopharyngeal carcinoma was conducted in Guangzhou, China. The reliability of the scale was evaluated using Cronbach's alpha. The factor structure was assessed using exploratory factor analysis (EFA) of each dimension. The EFA revealed that the 29-item self-rated scale has a seven-factor structure consistent with the original scale and explained 67.3% of the variance after extraction and rotation. The scale showed satisfactory reliability. The item-total correlations ranged from -0.16 to 0.64 (p < 0.05). The item-subscale correlations ranged from 0.46 to 0.91 (p < 0.05). The item-other subscale correlations ranged from -0.38 to 0.51 and from -0.21 to 0.56 (p < 0.05). Significant correlations were found between the timeline (acute/chronic) (r = 0.224, r = 0.166), consequences (r = 0.415, r = 0.338), timeline cyclical (r = 0.366, r = 0.284), emotional representations (r = 0.497, r = 0.465), personal control (r = -0.122, r = -0.134), treatment control (r = -0.135, r = -0.148), and illness coherence (r = -0.261, r = -0.213) subscales, and depression, anxiety (p < 0.05). The scale revealed acceptable reliability, factorial validity, and construct validity. It could be used to assess the illness representations of Chinese patients with nasopharyngeal carcinoma.

Medication nonadherence: health impact, prevalence, correlates and interventions

Nonadherence to medicines is a global problem compromising health and economic outcomes for individuals and society. This article outlines how adherence is defined and measured, and examines the impact, prevalence and determinants of nonadherence. It also discusses how a psychosocial perspective can inform the development of interventions to optimise adherence and presents a series of recommendations for future research to overcome common limitations associated with the medication nonadherence literature. Nonadherence is best understood in terms of the interactions between an individual and a specific disease/treatment, within a social and environmental context. Adherence is a product of motivation and ability. Motivation comprises conscious decision-making processes but also from more 'instinctive', intuitive and habitual processes. Ability comprises the physical and psychological skills needed to adhere. Both motivation and ability are influenced by environmental and social factors which influence the opportunity to adhere as well as triggers or cues to actions which may be internal (e.g. experiencing symptoms) or external (e.g. receiving a reminder). Systematic reviews of adherence interventions show that effective solutions are elusive, partly because few have a strong theoretical basis. Adherence support targeted at the level of individuals will be more effective if it is tailored to address the specific perceptions (e.g. beliefs about illness and treatment) and practicalities (e.g. capability and resources) influencing individuals' motivation and ability to adhere.

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.

Perceived sensitivity to medicines and medication concerns beliefs predict intentional nonadherence to antiretroviral therapy among young people living with HIV

Objective: Among the sources of antiretroviral therapy (ART) nonadherence are patient decisions to skip or stop taking their medications, often stemming from medication beliefs and concerns about side- effects. While individuals who perceive greater sensitivity to medicines may be prone to medication concerns, understanding how these factors contribute to HIV treatment adherence requires further research. The current study tested the direct and indirect effects of perceived sensitivity to medicines on intentional nonadherence to ART, and whether medication concerns mediate this association.Methods: A sample of 418 younger (< 36 years of age) people living with HIV was recruited through community outreach to complete assessments of perceived sensitivity to medicines, medication concerns beliefs, adherence assessed by unannounced phone- based pill counts and HIV viral load, as well as monthly follow- up assessments of intentional nonadherence over a 15- month period.Results: Analyses at baseline and prospective Poisson regression models conducted over 15- months converged to show that perceived sensitivity to medicines significantly predicted intentional nonadherence to ART through medication concerns.Conclusions: These findings suggest that people who perceive greater sensitivity to medicines are prone to greater medication concerns that are related to intentional nonadherence. Cognitive behavioral interventions are needed to resolve medication concerns and reduce intentional nonadherence among people receiving ART.

Stress at Home and Female Gender Are Significantly Associated With Non-adherence and Poor Illness Perception Among Patients With Rheumatoid Arthritis

Aims

We aimed to assess the level of non-adherence and poor illness perception among rheumatoid arthritis (RA) patients. Additionally, we examined their associations with clinical indicators and outcomes.

Methods

This was a cross-sectional study conducted using data collected at the time of patient enrolment in the Pakistan Registry of Rheumatic Diseases (PRIME) registry. A wide range of clinical variables was studied. To measure adherence, we used the Urdu version of the General Medication Adherence Scale (GMAS), which has recently been validated in RA patients. A Brief Illness Perception Questionnaire (BIPQ) was used to measure illness perception.

Results

The data of consecutive 320 RA patients were reviewed. Thirty-six percent of the cohort (n=116) was noted to have non-adherence. On multiple logistic regression analysis, a significant association of non-adherence was noted with moderate-to-severe stress (odds ratio {OR}: 1.85, confidence interval {CI}: 1.04-3.2), DAS-28 scores (OR: 1.83, CI: 1.52-2.21), Health Assessment Questionnaire (HAQ) scores (OR: 1.77, CI: 1.07-2.92), and deformed joint counts (OR: 1.30, CI: 1.15-1.46). Additionally, non-adherence due to "patient behavior" had a significant association with the male gender (OR: 0.48, CI: 0.26-0.87), unemployment (OR: 1.82, CI: 1.07-3.10), and stress at home (OR: 2.17, CI: 1.35-3.49). Twenty-six percent of the cohort (n=86) was noted to have the most negative illness perception, and on multiple logistic regression analysis, it was significantly associated with male gender (OR: 0.24, CI: 0.11-0.53), age of onset of arthritis (OR: 0.96, CI: 0.94-0.99), and worse HAQ scores (OR: 3.7, CI: 2.2-6.1).

Conclusions

Important adverse factors contributing to non-adherence and negative illness perception highlighted in this study were stress at home, female gender, and younger age of patients.

Illness perceptions, coping, and health-related quality of life among individuals experiencing chronic Lyme disease

OBJECTIVE

The aim of the present study was to examine illness perceptions and coping in relation to the health-related quality of life (HRQOL) among individuals experiencing chronic Lyme disease (CLD).

METHODS

Participants were 82 individuals who had a confirmed diagnosis of Lyme disease and had been experiencing symptoms for 6 months or more. They were recruited through various online mechanisms (e.g., social media, online support groups), and they completed the consent form and questionnaires via Qualtrics. Participants completed questions about their demographics and health status as well as the Illness Perception Questionnaire-Revised (Moss-Morris et al., 2002), the Brief COPE (Carver, 1997), and the 36-item Short Form Health Survey (SF-36; Ware & Sherbourne, 1992).

RESULTS

Illness perceptions and coping explained a significant amount of variance in HRQOL. Among the illness perceptions, the consequences and identity dimensions were most strongly associated with HRQOL. Behavioral disengagement and substance use were the coping strategies most strongly associated with the emotional health outcomes.

DISCUSSION

Illness perceptions and coping are related to HRQOL among individuals with CLD. Given the increase in Lyme disease incidence and the chronicity of symptoms in some cases, it is critical to continue to examine the psychosocial factors associated with HRQOL in this population.

Interaction between self-perceived disease control and self-management behaviours among Chinese middle-aged and older hypertensive patients: the role of subjective life expectancy

Background

One of the effective ways to control hypertension is long-term self-management, which is difficult to maintain. Therefore, understanding how people engage in the process of self-management behaviour change is necessary. In this study, we aimed to examine the dynamic relationship between self-perceived disease control and self-management behaviours in Chinese middle-aged and older hypertensive patients, namely, medication use, self-monitoring, physical activity, tobacco and alcohol avoidance, and to explore the mediating role of subjective life expectancy (SLE) on this relationship.

Methods

Data were obtained from a nationally representative sample of 508 middle-aged and older hypertensive patients (aged 45+) from the 2013, 2015, and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey. A cross-lagged panel model combined with mediation analysis was used to determine the dynamic relationship between self-perceived disease control and self-management behaviours and to clarify the mediating effect of SLE on this ascertained relationship.

Results

Good self-perceived disease control subsequently predicted good medication use, self-monitoring and physical activity, and vice versa. Subjective life expectancy (SLE) partially mediated the prospective reciprocal relationships between self-perceived disease control and these self-management behaviours, which accounted for 37.11, 25.88, and 19.39% of the total effect of self-perceived disease control on medication use, self-monitoring and physical activity, respectively. These self-management behaviours had a significant and positive feedback effect on self-perceived disease control. However, neither the direct and indirect effects (via SLE) of self-perceived disease control on tobacco and alcohol avoidance were revealed.

Conclusions

Positive feedback loops of present self-perceived disease control, future SLE and self-management behaviours (medication use, self-monitoring, and physical activity) help middle-aged and older hypertensive patients adhere to these behaviours but are useless for the avoidance of addictive behaviours. Interventions aimed at enhancing the effect perception of general self-management behaviours (e.g., medication use, self-monitoring and physical activity) on the present disease control perspective, and future lifespan perspective would be beneficial for the consistent self-management behaviours of middle-aged and older hypertensive patients. The utility of present disease control perception to these self-management behaviours was much higher than the utility of future expectations. Alternative stress relief strategies may be conducive to long-term changes in addictive behaviours.

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.

Psychometric approach to evaluate periodontal disease using Revised Illness Perception Questionnaire

Introduction:

Illness perception is the cognitive representation of an illness, which determines how a person responds to it. The Revised Illness Perception Questionnaire (IPQ-R) assesses seven components of illness representation in various chronic diseases, but queries prevail about its factor structure. The study assesses the components of illness representation in patients with chronic periodontitis.

Materials and Methods:

A total of 625 voluntary, consecutive dental patients with a clinical diagnosis of periodontitis were recruited into the study. The Hindi version of IPQ-R was used, consisting of three parts-identity scale, structured scale, and perceived causes of the patient's ailment.

Results:

Of the 625 participants, 44.0% reported cyclical disease pattern, 30.4% said their disease was a mystery. Only 1.6% predicted it to remain throughout their life. A total of 44.0% of participants reported the disease to impact their day-to-day life severely. A significant difference was observed between males and females across seven components of IPQ-R. While 21.6% of participants attributed stress to be a major cause for their diseased state, 20.8% reported workload to be a major cause, but 42.4% attributed poor medical care in the past to be a major cause for their state.

Conclusions:

A sensible approach to treating a disease is to measure the patient's illness perception and target specific interventions accordingly. It would be cost-effective and break misconceptions about diseases in patients, ultimately providing them with better overall health and satisfaction.

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 COVID-19 in Europe: Predictors, Impacts and Temporal Evolution

Objective: Illness perceptions (IP) are important predictors of emotional and behavioral responses in many diseases. The current study aims to investigate the COVID-19-related IP throughout Europe. The specific goals are to understand the temporal development, identify predictors (within demographics and contact with COVID-19) and examine the impacts of IP on perceived stress and preventive behaviors.

Methods: This was a time-series-cross-section study of 7,032 participants from 16 European countries using multilevel modeling from April to June 2020. IP were measured with the Brief Illness Perception Questionnaire. Temporal patterns were observed considering the date of participation and the date recoded to account the epidemiological evolution of each country. The outcomes considered were perceived stress and COVID-19 preventive behaviors.

Results: There were significant trends, over time, for several IP, suggesting a small decrease in negativity in the perception of COVID-19 in the community. Age, gender, and education level related to some, but not all, IP. Considering the self-regulation model, perceptions consistently predicted general stress and were less consistently related to preventive behaviors. Country showed no effect in the predictive model, suggesting that national differences may have little relevance for IP, in this context.

Conclusion: The present study provides a comprehensive picture of COVID-19 IP in Europe in an early stage of the pandemic. The results shed light on the process of IP formation with implications for health-related outcomes and their evolution.

Early termination in interdisciplinary pain rehabilitation: numbers, timing, and reasons. A mixed method study

PURPOSE

To analyse the number of, timing of, and reasons for early termination of interdisciplinary pain rehabilitation (IPR).

METHODS

A multicentre study in two Dutch rehabilitation centres with a mixed method design. Quantitative part: retrospective patient file review of all IPR patients. Qualitative part: 20 semi-structured patient interviews with early IPR terminators.

RESULTS

One hundred and thirty-seven of 428 participants (31.3%) had terminated IPR early, of which almost 30% had a positive reason. Of a planned treatment duration of 12 weeks, the median (interquartile range (IQR)) reduction was 5.3 week (3.0; 8.0). Over 80% of the early terminators with negative reasons stopped in the first half of IPR, whereas approximately 55% of the early terminators with positive reasons stopped in the final quarter of IPR. A discrepancy between patient expectations of the aim and content and the actual IPR was mentioned as a negative reason for early termination. Many of the positive early terminators were able to self-manage.

CONCLUSIONS

Previously reported figures on early termination were confirmed. Early termination of IPR should not be considered negative per se, because a substantial proportion of early terminations have a positive reason. Negative early terminators tend to stop earlier during IPR, compared to positive terminators.Implications for rehabilitationSubstantial rates of patients (31%) terminate interdisciplinary pain rehabilitation (IPR) earlier than planned.Early IPR termination should not be considered negative per se, because a substantial proportion of early terminations have a positive reason (i.e. goals achieved early).Although patients receive extensive personalised information about aim and content of IPR before starting, early terminators with a negative reason often have different expectations about the aim and content of treatment.Clinicians and researchers should be focused on how to explain IPR to the patient and check whether the patient has understood it well and is convinced of its credibility.

Effects of illness representation-focused patient education on illness representations and self-care in patients with heart failure: A randomised clinical trial

AIMS AND OBJECTIVES

To examine the effect of an illness representation-focused patient education intervention on illness representations and self-care behaviours in patients with heart failure 3 months after discharge from the hospital.

BACKGROUND

Few intervention studies have examined the effect of illness representation-focused interventions on illness representations and self-care in patients with heart failure.

DESIGN

A randomised clinical trial based on the Consolidated Standard of Reporting Trials-CONSORT 2010-guidelines was employed. The Clinical Trial Registry number is TCTR20190903002.

METHODS

One hundred and seven participants were randomly assigned to 2 groups, and 62 participants (n = 30 in the intervention group and n = 32 in the usual care group) completed the baseline and one- and three-month postdischarge follow-up assessments. The instruments included the Survey of Illness Beliefs in Heart Failure and the Self-care of Heart Failure Index. The intervention group received illness representation-focused patient education while hospitalised and telephone follow-ups after discharge. Data were analysed with linear mixed-effects model analysis.

RESULTS

The 107 participants had a mean age of 62.17 years and a mean left ventricular ejection of 53.03%. At baseline, the two groups tended to have accurate illness beliefs but insufficient self-care confidence and self-care maintenance. The analysis showed no significant differences between groups in the illness representation total scores, dimension scores or self-care maintenance scores but did show a significant difference in the self-care confidence scores (F = 3.42, p < .05) over the three months.

CONCLUSION

The study did not show an effect of the intervention on illness representations or self-care maintenance behaviours. However, the intervention did maintain participants' self-care confidence three months after discharge.

RELEVANCE TO CLINICAL PRACTICE

It is necessary to conduct long-term follow-ups of patients' illness representations, discuss the implementation of self-care behaviours with patients, enhance patients' self-care confidence, and involve family members or caregivers in self-care practices when needed.

Identifying high-need patients with multimorbidity from their illness perceptions and personal resources to manage their health and care: a longitudinal study

Background

A proactive person-centred care process is advocated for people with multimorbidity. To that aim, general practitioners may benefit from support in the identification of high-need patients, i.e. patients who are high or suboptimal users of health services and/or have a poor quality of life. To develop such support, we examined whether knowledge about patients’ illness perceptions and personal resources to manage their health and care is useful to identify high-need patients among multimorbid general practice populations.

Methods

Survey data, collected in 2016 and 2017, of 601 patients with two or more chronic diseases (e.g. COPD, diabetes, Parkinson’s disease) registered with 40 general practices in the Netherlands were analysed by logistic regression analysis to predict frequent contact with the general practice, contact with general practice out-of-office services, unplanned hospitalisations and poor health related quality of life. Patients’ illness perceptions and personal resources (education, health literacy, mastery, mental health status, financial resources, social support) were included as predictors.

Results

The four outcomes were only weakly associated among themselves (Phi .07–.19). Patients’ illness perceptions and personal resources were of limited value to predict potentially suboptimal health service use, but they were important predictors of health related quality of life. Patients with a poor health related quality of life could be identified by their previously reported illness perceptions (attributing many symptoms to their chronic conditions (B = 1.479, P < .001), a high level of concern (B = 0.844, P = .002) and little perceived control over their illness (B = -0.728, P = .006)) combined with an experienced lack of social support (B = -0.527, P = .042) and a poor mental health status (B = -0.966, P = .001) (sensitivity 80.7%; specificity 68.1%).

Conclusions

Multimorbid patients who frequently contact the general practice, use general practice out-of-office services, have unplanned hospitalisations or a poor health related quality of life are largely distinct high-need subgroups. Multimorbid patients at risk of developing a poor quality of life can be identified from specific illness beliefs, a poor mental health status and unmet social needs.

A systematic review of illness representation clusters in chronic conditions

A person's beliefs about their chronic condition (illness representations) influence health and treatment outcomes. Recently, researchers have used clustering approaches to identify subgroups with different patterns of beliefs about their illness, with some subgroups having more favorable health outcomes than others. To date, these findings have not been synthesized. The purpose of this systematic review of the literature was to synthesize results of studies that used clustering approaches to analyze illness representation in chronic disease populations, in order to characterize the clusters and their relationship to health outcomes. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines we searched CINAHL, PsycInfo, and PubMed. To be included, studies had to be (a) peer reviewed, (b) in English, (c) performing a cluster analysis (CA), latent class analysis (LCA), or latent profile analysis (LPA), (d) using only illness representation (IR) subscales to form clusters, (e) measuring illness representation with the Illness Perception Questionnaire (IPQ-R), (f) in a chronic condition sample, and (g) measuring health-related outcomes. Twelve studies were included. Across studies, the number of clusters found ranged from two to three. In all studies, an association was found between illness representation group and at least one of their health outcomes. Illness representation clusters associated with favorable outcomes usually included lower disease-related consequences, fewer symptoms, less negative emotion, and a more stable disease pattern. The results of this review indicate that the relationship between the patterns of the illness representation profiles and health outcomes transcend diseases. Additionally, some dimensions of illness representation may be more important drivers of group membership than others.

Applying the information-motivation-behavioral model to explore the influencing factors of self-management behavior among osteoporosis patients

BACKGROUND

The prevalence of osteoporosis (OP) is rapidly increasing. Healthy behaviors are crucial for the management of OP. Application of the information-motivation-behavioral skills (IMB) model has been verified in various chronic diseases, but this model has not been investigated for behavioral interventions among people with OP. This study aimed to examine factors influencing OP self-management behavior and their interaction paths based on the IMB model.

METHODS

We conducted a cross-sectional study using a convenience sampling method in 20 community health service centers in Shanghai, China. Predictive relationships between IMB model variables and self-management behaviors were evaluated using an anonymous questionnaire. Structural equation modeling was used to test the IMB model.

RESULTS

In total, 571 participants completed the questionnaire, of which 461 (80.7%) were female. Participants' mean age was 68.8 ± 10.1 years. Only 101 (17.7%) participants were classified as having better OP self-management behaviors. The model demonstrated the data had an acceptable fit. Paths from information to self-efficacy (β = 0.156, P < 0.001) and self-management behaviors (β = 0.236, P < 0.001), from health beliefs to self-efficacy (β = 0.266, P < 0.001), from medical system support to self-efficacy (β = 0.326, P < 0.001) and self-management behaviors (β = 0.230, P < 0.001), and from self-efficacy to self-management behaviors (β = 0.376, P < 0.001) were all significant and in the predicted direction.

CONCLUSION

This study validated the utility of the IMB model for OP self-management behaviors in this population. Middle-aged and older adult patients with OP have poor self-management behaviors. Enhanced knowledge about OP and is important for improving self-management behaviors.

Relación entre representación de enfermedad, representación del tratamiento y adherencia en adultos con asma: Una revisión

La adherencia al medicamento de control es el pilar fundamental para el control del asma; sin embargo, se ha identificado que una representación negativa de la enfermedad y el tratamiento impactan de modo negativo en esta. Se hizo una revisión narrativa para identificar los estudios empíricos acerca de representación de enfermedad, representación del tratamiento y adherencia a medicamentos de control en adultos con asma, desde el modelo de sentido común y representación de la enfermedad (MSCRE). Se identificaron 17 estudios divididos en transversales y longitudinales (12), experimentales (3) y de intervención (2), reportando que las principales dimensiones del MSCRE asociadas con la adherencia son la necesidad del tratamiento, preocupación, control de la enfermedad y del tratamiento, temporalidad crónica y consecuencias. Se concluye que el MSCRE es un modelo psicológico que tiene aplicaciones en la investigación y atención clínica para explicar y promover conductas de adherencia a medicamentos de control en adultos con asma.

Understanding sciatica: illness and treatment beliefs in a lumbar radicular pain population. A qualitative interview study

BACKGROUND

Several pathological processes contribute to lumbar radicular pain (LRP), commonly known as sciatica. It is not known how patients rationalise the experience of sciatica or understand the diagnosis. Providing clinicians with a better understanding of how patients conceptualise sciatica will help them to tailor information for patients on the management and treatment of the condition.

AIM

To understand patients' beliefs regarding their illness following a diagnosis of LRP, how these beliefs were developed, and the impact of illness beliefs on treatment beliefs.

DESIGN & SETTING

Qualitative interview study from a single NHS musculoskeletal interface service (in Wales, UK).

METHOD

Thirteen patients recently diagnosed with LRP were consecutively recruited. Individual semi-structured interviews were recorded and transcribed. Data were analysed using a thematic approach.

RESULTS

Four main themes were generated: (1) the illness experience (2) the concept of sciatica, (3) treatment beliefs, and (4) the desire for credible information.

CONCLUSION

The diagnosis of LRP is often communicated and understood within a compressive conceptual illness identity. Explaining symptoms with a compressive pathological model is easily understood by patients but may not accurately reflect the spectrum of pathological processes known to contribute to radicular pain. This model appears to inform patient beliefs about treatments. Clinicians should take care to fully explain the pathology prior to shared decision-making with patients.

The role of illness schemata in self-care behaviors and glycemic control among patients with type 2 diabetes in Iran

AIMS

The diabetes illness perception domains outlined by Leventhal's common-sense model may be weakly associated with hemoglobin A1c (HbA1c) and adherence to diabetes self-care behaviors. However, type 2 diabetes patients' illness schemata identified by clustering the illness perception domains remain to be explained. This study aimed to describe type 2 diabetes patients' illness schemata and to examine their association with self-care behaviors and glycemic control in Iran.

METHODS

A cross-sectional survey was conducted with 200 patients (mean age 59.5±10.3; 70% female) who attended self-management classes at the Iranian Diabetes Society in Tehran. Illness perceptions and self-care behaviors were assessed using the Persian version of the Illness Perception Questionnaire Revised and the Summary of Diabetes Self-Care Activity.

RESULTS

Three clusters of diabetes illness beliefs were identified: "empowered," "self-condemned," and "powerless." "Empowered" participants adhered most rigorously to general diet, fruit and vegetable intake, and exercise, and had the best glycemic control (HbA1c=7.2%, SD=0.2), followed by "self-condemned" and then "powerless" participants, who had the lowest adherence and the worst glycemic control (p<0.0001).

CONCLUSIONS

The clustering method for identifying type 2 diabetes patients' illness schemata is useful for selecting patients who need further care and assistance with adhering to self-care behaviors and glycemic control.

Illness Perceptions in Chronic Lymphocytic Leukemia: Testing Leventhal's Self-regulatory Model

BACKGROUND

Leventhal's Self-regulatory Model proposes that somatic characteristics of a health threat (e.g., symptom severity), and prior experience with the threat (e.g., unsuccessful treatment), are determinants of illness perceptions. Chronic lymphocytic leukemia (CLL) is appropriate for test of these postulates, having three phases differing in symptom severity and prior treatment experiences: indolent disease requiring no treatment (active surveillance; AS), symptomatic disease requiring a first treatment (FT), and highly symptomatic disease in those who have relapsed and/or failed to respond to prior treatments (relapsed/refractory; RR).

PURPOSE

To test symptom severity and prior treatment experiences as determinants of illness perceptions, illness perceptions were characterized and contrasted between CLL groups.

METHODS

Three hundred and thirty CLL patients (AS, n = 100; FT, n = 78; RR, n = 152) provided illness perception data on one occasion during a surveillance visit (AS) or prior to beginning treatment (FT, RR).

RESULTS

Analysis of variance with planned comparisons revealed that consequences, identity, and concern were least favorable among RR patients, followed by FT, then AS (ps < .01). AS patients endorsed the lowest levels of coherence (ps < .01), and the most chronic illness timeline (ps < .01). FT patients endorsed the highest levels of personal and treatment control (ps < .01).

CONCLUSIONS

Data provide preliminary empirical support for Self-regulatory Model postulates that symptom severity and prior disease experiences influence illness perceptions. Unique knowledge needs for AS patients and elevated psychological/physical symptoms for later-stage CLL patients may warrant clinical attention.

Dutch Translation and Adaptation of the Treatment Beliefs Questionnaire for Chronic Pain Rehabilitation

Background

The Treatment Beliefs Questionnaire has been developed to measure patients' beliefs of necessity of and concerns about rehabilitation. Preliminary evidence suggests that these beliefs may be associated with attendance of rehabilitation. The aim of this study was to translate and adapt the Treatment Beliefs Questionnaire for interdisciplinary pain rehabilitation and to examine the measurement properties of the Dutch translation including the predictive validity for dropout.

Methods

The questionnaire was translated in 4 steps: forward translation from English into Dutch, achieving consensus, back translation into English, and pretesting on providers and patients. In order to establish structural validity, internal consistency, construct validity, and predictive validity of the questionnaire, 188 participants referred to a rehabilitation centre for outpatient interdisciplinary pain rehabilitation completed the questionnaire at the baseline. Dropout was measured as the number of patients starting, but not completing the programme. For reproducibility, 51 participants were recruited at another rehabilitation centre to complete the questionnaire at the baseline and one week later.

Results

We confirmed the structural validity of the Treatment beliefs Questionnaire in the Dutch translation with three subscales, necessity, concerns, and perceived barriers. internal consistency was acceptable with ordinal alphas ranging from 0.66–0.87. Reproducibility was acceptable with ICC_{2,1 agreement} ranging from 0.67–0.81. Hypotheses testing confirmed construct validity, similar to the original questionnaire. Predictive validity showed the questionnaire was unable to predict dropouts.

Conclusion

Cross-cultural translation was successfully completed, and the Dutch Treatment Beliefs Questionnaire demonstrates similar psychometric properties as the original English version.

The impact of personal and cultural beliefs on medication adherence of patients with chronic illnesses: a systematic review

BACKGROUND

Patients' adherence to therapeutic regimes may be influenced by subjective beliefs about chronic conditions. One of the challenges for health professionals in enhancing adherence is taking patients' understanding into account when giving health advice and/or providing medical treatment.

PURPOSE

This review aimed to evaluate the consequent effects of personal and cultural beliefs on medication adherence, in patients with chronic conditions such as hypertension, diabetes mellitus, chronic obstructive pulmonary disease and asthma.

METHOD

A systematic review methodology was used. PubMed, CINAHL, EMBASE and PsychINFO, databases were searched for relevant articles. The main terms analyzed were illness perceptions, health beliefs, cultural beliefs, chronic conditions and medication adherence.

RESULTS

From 2,646 articles, 127 were retained for further assessment, and finally 25 met the inclusion criteria. A cross-sectional questionnaire survey research design was conducted in all included articles. Of these most (n=22) targeted hypertension or diabetes mellitus. A number of personal and cultural based factors were identified as being associated with adherence to medication regimes - 40% of articles (n=10) examined perception of illness, 20% (n=5) health literacy, 16% (n=4) cultural beliefs, 12% (n=3) self-efficacy, 16% (n=4) spiritual and religious beliefs, as well as 20% (n=5) illness knowledge. Statistically significant associations between medication adherence and these personal and cultural factors were found in 80% (n=20) of the included studies. However, the direction of associations varied between studies depending on the factor that was examined.

CONCLUSION

This review has evaluated the impact of personal and cultural factors on medication adherence and highlighted the gaps in literature regarding adherence. Further research is required to fully identify the associations between religious beliefs, control beliefs and illness knowledge and medication adherence.

A triadic perspective on control perceptions in youth with type 1 diabetes and their parents: Associations with treatment adherence and glycemic control

AIMS

A family approach was applied to examine youth, maternal, and paternal control perceptions in relation to type 1 diabetes outcomes in adolescents and emerging adults. Mean levels of personal and treatment control were compared among patients and parents. Their associations with diabetes outcomes were examined as well.

METHODS

The sample included 330 patient-mother-father triads. Patients' (48% male) mean age was 18.25 years (SD = 2.98). All respondents reported on their control perceptions and youth treatment adherence. Physicians provided HbA1c-values.

RESULTS

Paired-samples t-tests revealed higher personal control in patients compared to parents. Regression analyses examined if control perceptions predicted treatment adherence and HbA1c. Main effects for patient and maternal personal control and two-way interactions showed the best outcomes when both patients and mothers reported high personal control. Main effects of patient, maternal, and paternal treatment control and three-way interaction terms revealed better outcomes in case of high treatment control in patients and at least one parent, while the poorest outcomes were observed in case of low treatment control in all respondents.

CONCLUSIONS

The findings highlight the importance of parental control perceptions on top of patients' own perceptions. A family perspective on illness perceptions and their associations with diabetes outcomes is encouraged.

Self-management behaviors in World Trade Center rescue and recovery workers with asthma

BACKGROUND

Asthma is a major source of morbidity among World Trade Center (WTC) rescue and recovery workers. While physical and mental health comorbidities have been associated with poor asthma control, the potential role and determinants of adherence to self-management behaviors (SMB) among WTC rescue and recovery workers is unknown.

OBJECTIVES

To identify modifiable determinants of adherence to asthma self-management behaviors in WTC rescue and recovery worker that could be potential targets for future interventions.

METHODS

We enrolled a cohort of 381 WTC rescue and recovery workers with asthma. Sociodemographic data and asthma history were collected during in-person interviews. Based on the framework of the Model of Self-regulation, we measured beliefs about asthma and controller medications. Outcomes included medication adherence, inhaler technique, use of action plans, and trigger avoidance.

RESULTS

Medication adherence, adequate inhaler technique, use of action plans, and trigger avoidance were reported by 44%, 78%, 83%, and 47% of participants, respectively. Adjusted analyses showed that WTC rescue and recovery workers who believe that they had asthma all the time (odds ratio [OR]: 2.37; 95% confidence interval [CI]: 1.38-4.08), that WTC-related asthma is more severe (OR: 1.73; 95% CI: 1.02-2.93), that medications are important (OR: 12.76; 95% CI: 5.51-29.53), and that present health depends on medications (OR: 2.39; 95% CI: 1.39-4.13) were more likely to be adherent to their asthma medications. Illness beliefs were also associated with higher adherence to other SMB.

CONCLUSIONS

Low adherence to SMB likely contributes to uncontrolled asthma in WTC rescue and recovery workers. Specific modifiable beliefs about asthma chronicity, the importance of controller medications, and the severity of WTC-related asthma are independent predictors of SMB in this population. Cognitive behavioral interventions targeting these beliefs may improve asthma self-management and outcomes in WTC rescue and recovery workers. Key message: This study identified modifiable beliefs associated with low adherence to self-management behaviors among World Trade Center rescue and recovery rescue and recovery workers with asthma which could be the target for future interventions.

CAPSULE SUMMARY

Improving World Trade Center-related asthma outcomes will require multifactorial approaches such as supporting adherence to controller medications and other self-management behaviors. This study identified several modifiable beliefs that may be the target of future efforts to support self-management in this patient population.

Supporting Adherence to Medicines for Long-Term Conditions

Abstract. Pharmaceutical prescriptions are core to the treatment of most chronic illnesses, yet only half are taken as prescribed. Despite the high costs of nonadherence to individuals and society, effective adherence-promoting interventions are elusive. This is partly due to the sheer complicity of the issue. There are numerous determinants of adherence, both internal to the patient (intrinsic) and external (extrinsic, e.g., environmental or health system-related factors). Also, the relative importance of these determinants varies between individuals and even within the same individual over time and across treatments, presenting a challenge for intervention design. One complication is that interventions can target several levels: (1) patient (e.g., enhancing motivation and/or ability to adhere), (2) patient-provider interactions (e.g., improving communication and the prescribing process), and (3) the healthcare system (e.g., providing the opportunity to access medication through regulatory approval and co-payment schemes). Here, we focus on level 1: the patient. Although environmental factors are important, the effect of an intervention designed to change them will depend on how they impact on the individual. We describe the Perceptions and Practicalities Approach (PAPA), a pragmatic framework positing that adherence/nonadherence is essentially a produce of individual motivation and ability. Adherence interventions, targeted at any level, will therefore be more effective if tailored to address the perceptions and practicalities underpinning individual motivation and ability. We discuss how PAPA can be operationalized, including the application of theoretical models of illness and treatment representation (Necessity-Concerns Framework and Leventhal’s Common-Sense Model) to address salient adherence-related perceptions.

Psychometric approach of the revised illness perception questionnaire for oral health (IPQ-R-OH) in patients with periodontal disease

BACKGROUND

The purpose of this study was to evaluate the psychometric properties of the validated Spanish version of the Illness Perception Questionnaire Revised for Oral Health (IPQ-R-OH) in patients with periodontal disease.

METHODS

We used the IPQ-R-OH, a 36-item self-report scale. This study was carried out using data from 517 patients with periodontal disease attending the dental clinic at the Universidad Cooperativa de Colombia, Pasto, Colombia. A three-parameter logistic model (3PL) for polytomous response was calculated to evaluate a model of individuals' responses. The McDonald's Omega (Ω ≥ 0.60) coefficient and composite reliability were used to determine the internal consistency. Confirmatory factor analysis (CFA) was conducted to examine the fit of the hypothesized seven-factor model, and the configural invariance was tested to estimate the structure in each sex group.

RESULTS

The slope, location, and guessing parameters determined reasonable accurate items according to item response theory analysis. The internal consistency coefficients of each factor ranged from 0.62 to 0.93 (McDonald's Omega) and 0.66 to 0.87 (composite reliability). Confirmatory factor analysis indicated a seven-factor model (χ² _S-B  = 2572.165; χ² _S-B /(573) = 4.489, P < 0.01; non-normed fit index = 0.950; CFI = 0.950; root means square error of approximation = 0.055 (90% confidence interval [0.052 - 0.059]); standardized root mean residual = 0.080 and Akaike information criteria = 1426.165. The seven factors loaded similarly to the original IPQ-R scale. Multigroup CFA analysis results supported factor invariance across the sex groups.

CONCLUSION

These findings suggest that the IPQ-R-OH has adequate reliability and construct factorial validity; therefore, it could be a valuable instrument in screening illness perceptions in patients with periodontal disease.

Do individual versus illness belief schema differ in the prediction of post-stroke recovery?

This longitudinal observational study examined how individual versus illness belief schema compare as predictors of post-stroke recovery. A total of 42 stroke survivors (mean age = 66.9 years/range = 29–96 years; 68% male) were involved. The primary outcome, Health-Related Quality of Life was measured using EQ-5D-5L, mood using Patient Health Questionnaire-9 and disability using Nottingham Extended Activities of Daily Living Scale. Stroke Illness Perception Questionnaire-Revised measured illness beliefs. Linear regressions showed that individual illness beliefs significantly explained more of the variance in 3-month post-stroke recovery than schema (7.4%–22.5% versus 1.9%–9.9%). Individual versus illness belief schema predict outcomes differently, but which approach predicts outcomes better remains unclear.

A qualitative study of the experience of lower extremity wounds and amputations among people with diabetes in Philadelphia

The purpose of this study was to explore perceptions among people with type 2 diabetes about foot ulcers and lower extremity amputations. This was a qualitative observational study utilizing open-ended, semistructured interviews of 39 people with diabetes who were purposively selected because they had either a foot ulcer (n = 19) or a lower extremity amputation (n = 20). Interviews were audio-recorded, deidentified, and entered into NVivo 10.0 for coding and analysis. Our integrated analytic approach combined inductively and deductively derived codes that were applied to all transcripts. Coded data were summarized and examined for patterns. Participants' description of the relationship between diabetes and their foot ulcer or amputation revealed a limited understanding of the disease process. Disruption and loss of independence was expressed whether the person had a foot ulcer or an amputation. Treatment recommendations for foot ulcers were viewed by most as extremely difficult. Amputation was a feared outcome, but some learned to adapt and, at times felt that the amputation enhanced their quality of life. Clinicians have assumed that a focus on limb salvage is preferred over a major amputation. However, because of the complexity of care requiring frequent healthcare provider visits, the frequency of care failure, the frequency of recurrence, and mortality associated with having had a foot ulcer, it may be more appropriate for clinicians to prioritize quality-of-life salvage. Foot ulcer treatment failure may be due to a lack of providers' understanding of the impact of treatment on a patient's life.

Development of the Injury Perceptions Questionnaire (InjPQ)

OBJECTIVES

Injuries are major causes of morbidity and mortality in the population. Given the central role of perceptions in self-regulation of health conditions, it is important to investigate how they are perceived. This article describes the development of the Injury Perceptions Questionnaire (InjPQ).

METHODS

A concurrent study in a diverse sample of injured individuals (n = 333). The internal structure and the reliability (Cronbach's α) of InjPQ sub-scales were explored by factor analyses. Relationships between injury perception dimensions and equivalent illness perception scales and outcome measures (self-assessed health; physical, emotional and social functioning; depression, anxiety and somatisation; satisfaction with life) were investigated.

RESULTS

The InjPQ was found to represent the following perception scales: injury identity composed of social and body part components, PTSD symptoms, Injury event, Injury specific emotions, Injured self-image, Positive consequences, Responsibility/guilt, Coping, Time distance, Dependency, Healthy self, External attributions and Injury risk factors. The reliability and construct validity of the scales were found adequate.

CONCLUSIONS

Injury perceptions can be reliably measured. While partly overlapping with equivalent illness perception scales, the InjPQ depicts cognitive dimensions unique to injury that add significantly to explaining variance in outcomes. The InjPQ is recommended for research and clinical use as a measure of injury perceptions.
