Clinimetric properties of illness perception questionnaire revised (IPQ-R) and brief illness perception questionnaire (Brief IPQ) in patients with musculoskeletal disorders: A systematic review

Preoperative glycaemic control, number of pain locations, structural knee damage, self-reported central sensitisation, satisfaction and personal control are predictive of 1-year postoperative pain, and change in pain from pre- to 1-year posttotal knee arthroplasty

PURPOSE

The aim of this study was to identify preoperative predictors for 1-year posttotal knee arthroplasty (TKA) pain and pre- to post-TKA pain difference in knee osteoarthritis (KOA) patients.

METHODS

From March 2018 to July 2023, this prospective longitudinal cohort study enrolled KOA patients awaiting TKA from four hospitals in Belgium and the Netherlands. Different biopsychosocial predictors were assessed preoperatively by questionnaires and physical examinations (input variables). The Knee injury and Osteoarthritis Outcome Score (KOOS) subscale pain was used to measure pain intensity. The absolute KOOS subscale pain score 1-year post-TKA and the difference score (ΔKOOS = 1-year postoperative - preoperative) were used as primary outcome measures (output variables). Two multivariable linear regression analyses were performed.

RESULTS

Two hundred and twenty-three participants were included after multiple imputation. Worse absolute KOOS subscale pain scores 1-year post-TKA and negative or closer to zero ΔKOOS subscale pain scores were predicted by self-reported central sensitisation, lower KOA grade and preoperative satisfaction, and higher glycated haemoglobin, number of pain locations and personal control (adjusted R2 = 0.25). Additional predictors of negative or closer to zero ΔKOOS subscale pain scores were being self-employed, higher preoperative pain and function (adjusted R2 = 0.37).

CONCLUSION

This study reports different biopsychosocial predictors for both outcomes that have filtered out other potential predictors and provide value for future studies on developing risk assessment tools for the prediction of chronic TKA pain.

A Chinese version of the Stroke Illness Perception Questionnaire-Revised: Reliability and validity assessment in stroke patients

BACKGROUND

Illness perceptions are an important factor affecting the prognosis of stroke patients. Evaluating the illness perceptions of stroke patients is of great importance for predicting their health behaviour and rehabilitation outcomes. However, there is no specific tool for assessing illness perceptions in stroke patients in China.

OBJECTIVES

The objective of this study is to translate the Stroke Illness Perception Questionnaire-Revised (SIPQ-R) into Chinese and to psychometrically test the Chinese version of the scale in the population of Chinese stroke patients.

METHODS

This was a methodological study. We investigated 593 stroke patients in the neurology department of a hospital in China from March to September 2021. We translated the SIPQ-R and adapted it to the cultural context, after which we evaluated the reliability and validity of the Chinese version of SIPQ-R.

RESULTS

Exploratory factor analysis identified eight common factors that accounted for 71.74% of the total variance, and the factor loadings ranged from 0.530 to 0.933. Confirmatory factor analysis confirmed the eight-factor structure (χ2/df = 1.765, root mean square error of approximation = 0.053, incremental fit index = 0.906, comparative fit index = 0.905 and Tucker-Lewis index = 0.900). Internal consistency was confirmed by a Cronbach's alpha coefficient of 0.982. The test-retest reliability was 0.762. The results showed good content validity (the scale level content validity index was 0.940, and the item level content validity index values ranged from 0.860 to 0.960). There were no missing responses and floor or ceiling effects. The standard error of measurement and the smallest detectable change for the SIPQ-R were 45.49 and 126.10, respectively.

CONCLUSIONS

The results of this study provide empirical evidence for the reliability and validity of the Chinese version of the SIPQ-R for stroke patients.

The impact of an illness perception conversation on open-label placebo response in knee osteoarthritis: A randomised controlled trial

OBJECTIVE

To compare the effect of an illness perception conversation (IPC), relative to a research participation conversation (RPC), on 2-week changes in knee pain in patients with knee osteoarthritis.

METHOD

This was a randomised single-blind trial. Patients were randomised to two matched conversations. An IP conversation concerning the participant's knee pain-related illness perception (IP) or an RPC concerning the participant's motivation for participating in research. Both conversations were followed by an open-label intraarticular saline injection in the most symptomatic knee. The primary outcome was change in knee pain from baseline to 2 weeks follow-up on a 100 mm visual analogue scale (VAS). Key secondary outcomes included the Knee injury and Osteoarthritis Outcome Score (KOOS) subscales: Activities of daily living (ADL) and Quality of life (QoL). Main analyses were based on the intention-to-treat population using repeated measures mixed effects linear models.

RESULTS

103 patients were randomised to the IPC group (n = 52) and the RPC group (n = 51). VAS knee pain scores changed statistically significantly from baseline to end of treatment in both groups, -13.7 (standard error [SE]: 3.2) in the IPC group and -13.0 (SE: 3.1) in the RPC group with an adjusted between-group difference of -0.7 (95% CI: -8.3 to 6.9; P = 0.85). Likewise, no group differences were seen in KOOS ADL and KOOS QoL.

CONCLUSION

A conversation concerning knee pain-related IP did not augment the pain-relieving effect of an open-label placebo injection when compared to a similar control conversation concerning motivations for participating in research.

Remote monitoring of rheumatoid arthritis (REMORA): study protocol for a stepped wedge cluster randomized trial and process evaluation of an integrated symptom tracking intervention

BACKGROUND

Management of rheumatoid arthritis (RA) relies on symptoms reported by patients during infrequent outpatient clinic visits. These reports are often incomplete and inaccurate due to poor recall, leading to suboptimal treatment decisions and outcomes. Asking people to track symptoms in-between visits and integrating the data into clinical pathways may improve this. However, knowledge on how to implement this into practice and its impact on services and outcomes remains scarce in RA. Therefore, we evaluate the comparative effectiveness and cost-effectiveness of integrated symptom tracking in people with RA over and above usual care, while generating insights on factors for successful implementation.

METHODS

In this superiority stepped wedge cluster-randomized controlled trial with continuous recruitment short exposure design, 16 rheumatology outpatient departments (clusters) recruit a total of 732 people with active RA. They initially offer clinic visits according to standard of care before switching in pairs to visits with integrated symptom tracking. Clusters switch in randomized order every 3 weeks. Integrated symptom tracking consists of (1) a mobile app for patients to track their symptoms daily and other RA aspects weekly/monthly, and (2) an interactive dashboard visualizing the app data, which healthcare professionals access from their electronic health record system. Clinic visits happen according to usual practice, with tracked symptom data only reviewed during visits. Our primary outcome is a difference in marginal mean disease activity score at 12 ± 3 months between standard of care and integrated symptom tracking, after accounting for baseline values, cluster, and other covariates. Secondary outcomes include patient-reported disease activity, quality of life and quality-adjusted life-years, medication/resource use, consultation and decision-making experience, self-management, and illness perception. We also conduct interviews and observations as part of a parallel process evaluation to gather information on implementation.

DISCUSSION

Our trial will generate high-quality evidence of comparative and cost-effectiveness of integrated symptom tracking compared to standard of care in people with RA, with our process evaluation delivering knowledge on successful implementation. This optimizes the chances of integrated symptom tracking being adopted more widely if we find it is (cost-) effective.

Technology supported High Intensity Training in chronic non-specific low back pain (the Techno-HIT trial): study protocol of a randomised controlled trial

Chronic low back pain (CLBP) is one of the most common chronic musculoskeletal disorders worldwide. Guidelines recommend exercise therapy (ET) in CLBP management, but more research is needed to investigate specific ET modalities and their underlying mechanisms. The primary goal of this study is to evaluate the short-term and long-term effectiveness of a time-contingent individualised high-intensity training (HIT) protocol on disability compared with a time-contingent moderate-intensity training (MIT) as used in usual care, in persons with severely disabling CLBP. Additionally, the effectiveness on central effects, the added value of prolonged training at home and technology support, and the cost-effectiveness are evaluated. In this randomised controlled trial, CLBP patients will be randomly divided into three groups of 56 participants. Group 1, 'TechnoHIT', receives HIT with technology-support in the home-phase. Group 2, 'HIT', receives HIT without technology support. Group 3, 'MIT', receives MIT, reflecting training intensity as used in usual care. The primary outcome is patient-reported disability, measured by the Modified Oswestry Disability Index. Secondary outcomes include quantitative sensory testing, psychosocial factors, broad physical fitness, quality of life, cost-effectiveness, adherence and usability of technology. Trial registration number NCT06491121.

Opioid Misuse by Adults with Chronic Pain: The Impact of Illness and Medication Beliefs

BACKGROUND

Why do some adults with chronic pain misuse their prescription opioids when others do not? Based on the extended Common-Sense Model, the study evaluated whether adults' beliefs about their pain have an indirect effect on risk of opioid misuse through beliefs about opioids when controlling for depression.

METHODS

The sample included 297 adult participants in the U.S. recruited from Prolific, an online crowdsourcing website. Study measures included the Illness Perception Questionnaire-Revised (IPQ-R; protective and threat-related illness beliefs about chronic pain), the Beliefs about Medicines Questionnaire-Specific subscale (BMQ-Specific; concern and necessity medication beliefs about prescription opioids), and the Current Opioid Misuse Measure (COMM; risk of current opioid misuse). This cross-sectional parallel mediation analysis was conducted using MPlus.

RESULTS

After controlling for depression, the indirect effect of protective illness beliefs on opioid misuse risk through concern medication beliefs (b = -0.01, 95% CI (-0. 038, -0.001), and the indirect effect of threat-related illness beliefs on opioid misuse risk through necessity medication beliefs (b = 0.02, 95% CI (0.004, 0.036) were significant. The full model explained 35% of the variance of opioid misuse risk.

CONCLUSIONS

Adults with chronic pain with stronger protective beliefs about pain were less likely to have concerns about their opioids and were at lower risk for opioid misuse, while those with greater threat-related beliefs about pain were more likely to believe that their opioids were necessary and be at greater risk for opioid misuse. Results have implications for medical and mental health providers and future research.

Changes in illness perception, pain catastrophizing, and psychological distress following hand surgeon consultation: A prospective study

BACKGROUND

Baseline mindset factors are important factors that influence treatment decisions and outcomes. Theoretically, improving the mindset prior to treatment may improve treatment decisions and outcomes. This prospective cohort study evaluated changes in patients' mindset following hand surgeon consultation. Additionally, we assessed if the change in illness perception differed between surgical and nonsurgical patients.

METHODS

The primary outcome was illness perception, measured using the total score of the Brief Illness Perception Questionnaire (B-IPQ, range 0-80). Secondary outcomes were the B-IPQ subscales, pain catastrophizing (measured using the Pain Catastrophizing Scale (PCS)), and psychological distress (measured using the Patient Health Questionnaire-4).

RESULTS

A total of 276 patients with various hand and wrist conditions completed the mindset questionnaires before and after hand surgeon consultation (median time interval: 15 days). The B-IPQ total score improved from 39.7 (±10.6) before to 35.8 (±11.3) after consultation (p < 0.0001, Cohen's d = 0.36); scores also improved for the B-IPQ subscales Coherence, Concern, Emotional Response, Timeline, Treatment Control, and Identity and the PCS. There were no changes in the other outcomes. Surgical patients improved on the B-IPQ subscales Treatment Control and Timeline, while nonsurgical patients did not.

CONCLUSIONS

Illness perception and pain catastrophizing improved following hand surgeon consultation, suggesting that clinicians may actively influence the patients' mindset during consultations, and that they may try to enhance this effect to improve outcomes. Furthermore, surgical patients improved more in illness perceptions, indicating that nonsurgical patients may benefit from a more targeted strategy for changing mindset.

Psychosocial Factors, Sleep, and Central Pain Processing for Making a Prognosis About Recovery of Pain, Function, and Quality of Life After Rotator Cuff Repair: An Exploratory Longitudinal Study

OBJECTIVE: To explore modifiable psychosocial factors, sleep-related variables, indices of central pain processing and patients' characteristics as potential prognostic factors for pain, shoulder function, and quality of life (QoL) 1 year after rotator cuff repair. DESIGN: This observational longitudinal study included 142 patients who were undergoing rotator cuff repair. All measures took place pre-rotator cuff repair (T0), and 12 weeks (T1) and 12 months (T2) after rotator cuff repair. METHODS: Mixed-effects linear regression modeled relationships between the Western Ontario Rotator Cuff Index (WORC, model A), the Subjective Shoulder Value (SSV, model B), and EuroQol's EQ-5D-5L for QoL (model C), and potential prognostic factors over time. Factors included psychosocial variables, sleep-related indices, and proxies of central pain processing. Patients' age, sex, and body mass index complemented the analyses. RESULTS: At follow-up (T2), data from 124 participants were available for analysis. Five prognostic factors were identified for the 1-year outcome. Better expectations for symptom reduction (P<.0001, -1.4 mm) and an increase in Douleur Neuropathique 4 score (P = .0481, -0.9 mm) affected the evolution of WORC over time (model A). An increase in injury perception subscale consequence (P = .0035, 0.04%) influenced the SSV trajectory (model B). In addition, when sleep quality (P = .0011, -0.13%) and sleep efficiency (P = .0002, 0.005%) improved, the EQ-5D-5L slope was affected (model C). CONCLUSION: Addressing cognitions, pain mechanisms and sleep behavior prior to rotator cuff repair can identify people who are at risk of a poor outcome after surgery.

Internal consistency reliability of the Revised Illness Perceptions Questionnaire: A systematic review and reliability generalization meta-analysis

The Revised Illness Perception Questionnaire (IPQ-R) assesses patients' perspectives of their illnesses. Original psychometric testing occurred in limited populations. The purpose of this reliability generalization meta-analysis was to: (1) estimate internal consistency reliability of each IPQ-R subscale, and (2) test moderators of these estimates. Web of Science was searched in July 2022 for articles citing the original IPQ-R paper that reported IPQ-R reliability data. Cronbach's alphas (⍺) were pooled for each IPQ-R subscale using inverse variance weighting and DerSimonian and Laird estimation. Sixty-six studies met criteria. Overall pooled ⍺ estimates were acceptable: 0.71-0.87. Treatment control reliability was reduced among cardiac (⍺ = 0.68), diabetes/kidney disease (⍺ = 0.63), and mixed/other (⍺ = 0.66) samples; cyclical reliability was reduced in cancer (⍺ = 0.65) samples. Age, gender, and race were also significant moderators. Subscale reliability varied based on sample characteristics. Adapting IPQ-R subscales to account for sample variation could improve measurement of illness perception constructs.

Health literacy and self-management among middle-aged and young hypertensive patients: a parallel mediation effect of illness perception and self-efficacy

Background

Hypertension is increasingly prevalent among young and middle-aged populations in rural China, accompanied by suboptimal self-management. Given that this population forms the backbone of the labor force, enhancing their self-management capabilities is crucial for improving overall population health. Studies indicate that individuals with good health literacy are more likely to effectively manage their health.

Methods

Grounded in the health literacy skills framework, a model was constructed in this study to examine the impact of health literacy on self-management among young and middle-aged hypertensive patients in rural China. Meanwhile, the mediating roles of illness perception and self-efficacy were also verified. Using a multi-stage stratified random sampling method, 338 patients were recruited to participate in the study. Structural equation modeling was utilized to establish the relationship model, and bootstrap tests were carried out to examine the mediating effects.

Results

The average self-management score was 70.45 ± 11.36. Health literacy exhibited a positive correlation with self-management (standardized β = 0.372, p < 0.001). The mediating effects through illness perception and self-efficacy were 0.040 and 0.236, constituting 6.68 and 39.31% of the total effect, respectively.

Conclusion

Illness perception and self-efficacy serve as parallel mediators amid the association between health literacy and self-management. Implementing psychological counseling and health education is imperative for augmenting self-management competence and cultivating an adaptive coping mentality.

Analysis of trajectory changes and predictive factors of sense of coherence in patients after colorectal cancer surgery

OBJECTIVE

To investigate the trajectories and potential categories of changes in the sense of coherence (SOC) in patients after colorectal cancer surgery and to analyze predictive factors.

METHODS

From January to July 2023, 175 patients with colorectal cancer treated at a tertiary Grade A oncology hospital in Jiangsu Province were selected as the study subjects. Prior to surgery, SOC-13 scale, Patient-Generated Subjective Global Assessment (PG-SGA), Brief Illness Perception Questionnaire (BIPQ), and Social Support Rating Scale (SSRS) were used to survey the patients. SOC levels were measured multiple times at 1 week, 1 month, and 3 months post-surgery. Growth Mixture Modeling (GMM) was applied to fit the trajectory changes of SOC in patients after colorectal cancer surgery. Multinomial logistic regression was used to analyze the predictive factors of SOC trajectory changes.

RESULTS

The SOC scores of patients at points T1-T4 were (65.27 ± 9.20), (63.65 ± 10.41), (63.85 ± 11.84), and (61.56 ± 12.65), respectively. Multinomial logistic regression results indicated that gender, employment status, disease stage, household monthly income, intestinal stoma, nutritional status, illness perception, and social support were predictors of SOC trajectory changes (P < 0.05).

CONCLUSION

There is heterogeneity in the trajectory changes of SOC in patients after colorectal cancer surgery. Healthcare professionals should implement early precision interventions based on the patterns of changes and predictive factors in each trajectory category.

Illness perceptions in people with chronic and disabling non-specific neck pain seeking primary healthcare: a qualitative study

BACKGROUND

Illness perceptions can affect the way people with musculoskeletal pain emotionally and behaviorally cope with their health condition. Understanding patients illness perceptions may help facilitate patient-centered care. The purpose of this study was to explore illness perceptions and the origin of those perceptions in people with chronic disabling non-specific neck pain seeking primary care.

METHODS

A qualitative study using a deductive and inductive analytical approach was conducted in 20 people with persistent (> 3 months) and disabling (i.e., Neck Disability Index ≥ 15) neck pain. Using a semi-structured format, participants were interviewed about their illness perceptions according to Leventhal's Common Sense Model. Purposive sampling and member checking were used to secure validity of study results.

RESULTS

Participants reported multiple symptoms, thoughts and emotions related to their neck pain, which continuously required attention and action. They felt trapped within a complex multifactorial problem. Although some participants had a broader biopsychosocial perspective to understand their symptoms, a biomedical perspective was dominant in the labelling of their condition and their way of coping (e.g., limiting load, building strength and resilience, regaining mobility, keep moving and being meaningful). Their perceptions were strongly influenced by information from clinicians. Several participants indicated that they felt uncertain, because the information they received was contradictory or did not match their own experiences.

CONCLUSION

Most participants reported that understanding their pain was important to them and influenced how they coped with pain. Addressing this 'sense making process' is a prerequisite for providing patient-centered care.

The Ultrashort Mental Health Screening Tool Is a Valid and Reliable Measure With Added Value to Support Decision-making

BACKGROUND

Mental health influences symptoms, outcomes, and decision-making in musculoskeletal healthcare. Implementing measures of mental health in clinical practice can be challenging. An ultrashort screening tool for mental health with a low burden is currently unavailable but could be used as a conversation starter, expectation management tool, or decision support tool.

QUESTIONS/PURPOSES

(1) Which items of the Pain Catastrophizing Scale (PCS), Patient Health Questionnaire (PHQ-4), and Brief Illness Perception Questionnaire (B-IPQ) are the most discriminative and yield a high correlation with the total scores of these questionnaires? (2) What is the construct validity and added clinical value (explained variance for pain and hand function) of an ultrashort four-item mental health screening tool? (3) What is the test-retest reliability of the screening tool? (4) What is the response time for the ultrashort screening tool?

METHODS

This was a prospective cohort study. Data collection was part of usual care at Xpert Clinics, the Netherlands, but prospective measurements were added to this study. Between September 2017 and January 2022, we included 19,156 patients with hand and wrist conditions. We subdivided these into four samples: a test set to select the screener items (n = 18,034), a validation set to determine whether the selected items were solid (n = 1017), a sample to determine the added clinical value (explained variance for pain and hand function, n = 13,061), and a sample to assess the test-retest reliability (n = 105). Patients were eligible for either sample if they completed all relevant measurements of interest for that particular sample. To create an ultrashort screening tool that is valid, reliable, and has added value, we began by picking the most discriminatory items (that is, the items that were most influential for determining the total score) from the PCS, PHQ-4, and B-IPQ using chi-square automated interaction detection (a machine-learning algorithm). To assess construct validity (how well our screening tool assesses the constructs of interest), we correlated these items with the associated sum score of the full questionnaire in the test and validation sets. We compared the explained variance of linear models for pain and function using the screening tool items or the original sum scores of the PCS, PHQ-4, and B-IPQ to further assess the screening tool's construct validity and added value. We evaluated test-retest reliability by calculating weighted kappas, ICCs, and the standard error of measurement.

RESULTS

We identified four items and used these in the screening tool. The screening tool items were highly correlated with the PCS (Pearson coefficient = 0.82; p < 0.001), PHQ-4 (0.87; p < 0.001), and B-IPQ (0.85; p < 0.001) sum scores, indicating high construct validity. The full questionnaires explained only slightly more variance in pain and function (10% to 22%) than the screening tool did (9% to 17%), again indicating high construct validity and much added clinical value of the screening tool. Test-retest reliability was high for the PCS (ICC 0.75, weighted kappa 0.75) and B-IPQ (ICC 0.70 to 0.75, standard error of measurement 1.3 to 1.4) items and moderate for the PHQ-4 item (ICC 0.54, weighted kappa 0.54). The median response time was 43 seconds, against more than 4 minutes for the full questionnaires.

CONCLUSION

Our ultrashort, valid, and reliable screening tool for pain catastrophizing, psychologic distress, and illness perception can be used before clinician consultation and may serve as a conversation starter, an expectation management tool, or a decision support tool. The clinical utility of the screening tool is that it can indicate that further testing is warranted, guide a clinician when considering a consultation with a mental health specialist, or support a clinician in choosing between more invasive and less invasive treatments. Future studies could investigate how the tool can be used optimally and whether using the screening tool affects daily clinic decisions.

Prevalence and perceptions of pain in people with haemophilia: A UK study

INTRODUCTION

Joint bleeds in haemophilia cause destruction of articular structures, impaired function and pain. Up to 70% of people with haemophilia (PWH) report chronic pain. Little is known about the pain experiences in PWH in the UK.

AIM

To identify prevalence and perceptions of pain among PWH living in the UK.

METHODS

A cross-sectional, non-interventional survey study conducted among PWH (all severities). The survey incorporated elements from validated tools (EQ-5D; EQ-VAS) and was distributed via participating treatment centres.

RESULTS

Five hundred and ninety-nine PWH responded, 91% aged > 18. 81% used factor prophylactically or on demand. More pain was reported by those treated on demand versus prophylaxis particularly in those who reported daily pain. 65% reported 'problem joints' based on individual impact rather than medically defined 'target joints', 2/3 reported multiple joint issues. The ankle was most commonly affected. 59% reported frequent pain, with 56% aware of pain constantly or most of the time and were more likely to report less favourable EQ-5D or EQ-VAS scores (p < .001). Pain frequency/awareness was consistent across all severities. Most discussed pain with care teams, 31% only when asked; 25% did not discuss it. Pain discussions resulted in physiotherapy referral (63%) analgesia prescription (48%), and a minority specialist pain referral (9%). Most felt well supported with regard to their pain, but 70% reported learning to live with it.

CONCLUSION

Pain affects PWH of all ages and severities even in a well-resourced country significantly impacting quality of life. Clinicians must be more aware of chronic pain in PWH. Biopsychosocial approaches to pain assessment and management are recommended.

Baseline mindset factors are important factors that influence treatment decisions and outcomes. Theoretically, improving the mindset prior to treatment may improve treatment decisions and outcomes. This prospective cohort study evaluated changes in patients' mindset following hand surgeon consultation. Additionally, we assessed if the change in illness perception differed between surgical and nonsurgical patients.

Secondary outcomes were the B-IPQ subscales, pain catastrophizing (measured using the Pain Catastrophizing Scale (PCS)), and psychological distress (measured using the Patient Health Questionnaire-4).

RESULTS

A total of 276 patients with various hand and wrist conditions completed the mindset questionnaires before and after hand surgeon consultation (median time interval: 15 days). The B-IPQ total score improved from 39.7 (±10.6) before to 35.8 (±11.3) after consultation (p < 0.0001, Cohen's d = 0.36); scores also improved for the B-IPQ subscales Coherence, Concern, Emotional Response, Timeline, Treatment Control, and Identity and the PCS. There were no changes in the other outcomes. Surgical patients improved on the B-IPQ subscales Treatment Control and Timeline, while nonsurgical patients did not.

CONCLUSIONS

Illness perception and pain catastrophizing improved following hand surgeon consultation, suggesting that clinicians may actively influence the patients' mindset during consultations, and that they may try to enhance this effect to improve outcomes. Furthermore, surgical patients improved more in illness perceptions, indicating that nonsurgical patients may benefit from a more targeted strategy for changing mindset.

Assessing the Effect of Cancer Diagnosis on Beliefs about Comorbid Diabetes

OBJECTIVES

Increasingly, patients diagnosed with cancer also live with chronic comorbidities, and it is important to understand the impact of a new cancer diagnosis on perceptions about preexisting conditions. This study assessed the effect of cancer diagnosis on beliefs about comorbid diabetes mellitus and assessed changes in beliefs about cancer and diabetes over time.

DATA SOURCES

We recruited 75 patients with type 2 diabetes who were newly diagnosed with early-stage breast, prostate, lung, or colorectal cancer and 104 age-, sex-, and hemoglobin A1c-matched controls. Participants completed the Brief Illness Perception Questionnaire four times over 12 months. The authors examined within-patient and between-group differences in cancer and diabetes beliefs at baseline and over time.

RESULTS

Overall, diabetes beliefs did not differ between cancer patients and controls at baseline. Cancer patients' beliefs about diabetes varied significantly over time; they reported less concern about cancer, less emotional effect, and greater cancer knowledge over time. Participants without cancer were significantly more likely to report that diabetes affected their life across all time points, though this effect did not persist after adjustment for sociodemographic variables.

CONCLUSION

While all patients' diabetes beliefs were similar at baseline and 12 months, cancer patients' beliefs about both illnesses fluctuated during the months following cancer diagnosis.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses can play a key role in recognizing the effects of cancer diagnosis on beliefs about comorbid conditions and fluctuations in these beliefs during treatment. Assessing and communicating patient beliefs between oncology and other practitioners could produce more effective care plans based on patients' current outlook on their health.

Determining key clinical predictors for chronic ankle instability and return to sports with cost of illness analysis: protocol of a prospective cohort study

INTRODUCTION

Ankle sprains are common in sports and the general population. Although considered innocuous, a large proportion has residual complaints such as recurrent ankle sprains and develop chronic ankle instability. Although some predicting factors are identified, there is no unequivocality regarding the development of chronic ankle instability, nor about the optimal rehabilitation for an acute ankle sprain. Alongside the biomechanical impairments, ankle sprains are a burden on society due to substantial economic costs. Therefore, we aim to identify key clinical predictors of chronic ankle instability or recovery after acute lateral ankle sprain. Additionally, we aim to determine cost-of-illness of patients who developed chronic ankle instability.

METHODS AND ANALYSIS

This prospective cohort study (Clinicaltrials.gov: NCT05637008 - pre-results) aims to recruit adult (18-55 years) patients with an acute lateral ankle sprain who are active in sports. Clinical assessments and patient-reported outcome measures will be used to collect data at 7-14 days, 6 weeks, 12 weeks and 12 months after enrolment in the study. The primary outcome will be chronic ankle instability at 12-month follow-up. Salient outcomes will be analysed by logistic regression to determine association with the development of chronic ankle instability. Participants will fill in a cost diary containing direct and indirect costs related to their injury.

ETHICS AND DISSEMINATIONS

The ethical committee of the Antwerp University Hospital (B3002022000138) has given approval of the protocol and consent forms on 10 October 2022. We perform this study according to the Helsinki Declaration. We will present results at conferences or webinars and publish in peer-reviewed articles.NCT05637008.

Patient adherence to physical activity advice (PAPA) in patients with low back pain: Study protocol for a multicentre randomized controlled trial

BACKGROUND

It seems that nonspecific low back pain (NSLBP) cannot be successfully treated with a single intervention of any kind. However, a positive effect of an active lifestyle including physical activities in NSLBP is reported on pain and disability. Advising regular physical activity is one of the mainstays in physical therapy treatment, appealing to patients' adherence. Many patients with low back pain do not seem to adhere to their physiotherapist's advice. In this study, the influence of social support on adherence to an activity advice will be investigated.

OBJECTIVE

Objective of the study is to investigate if patients with low back pain randomised to receive social support adhere better to an activity advice than patients randomised to the control group.

METHODS

In a randomized controlled clinical trial, in private physiotherapy practices in the Netherlands, patients ≥18 years presenting with at least a second episode of nonspecific low back pain will be randomized over two groups: activity advice and social support as an add-on to usual care versus usual care alone. The primary outcome measure is adherence to an activity advice measured by an activity monitor at 1, 6 and 12 weeks. All other objectives will be measured by questionnaires.

DISCUSSION

This project is the first comprehensive research project to assess whether social support influences adherence to an activity advice outside the clinical setting without supervision of a healthcare provider. Where evidence of influence on social support is lacking, findings may have implications for the management of patients with low back pain. In addition, findings may enable physiotherapists to predict in which patients with low back pain an activity advice with social support makes sense.

Validity and reliability of the Arabic version of the revised illness perception questionnaire for patients with hypertension

Background

Hypertension is one of the leading causes of morbidity and mortality in Saudi Arabia affecting 31.4% of the population. The Illness Perception Questionnaire-Revised (IPQ-R) is a validated and reliable tool for assessing the perception of hypertension among patients. This cross-sectional study aimed to translate the Revised Illness Perception Questionnaire (IPQ-R) into Arabic and validate it among Arabic patients with hypertension from the outpatient departments of the Prince Sattam University Hospital and King Khalid Hospital (KKH) in Al-Kharj City in the Kingdom of Saudi Arabia.

Methods

A bilingual panel of doctors and medical translators was assembled to translate the IPQ-R into Arabic. The questionnaire was administered to 100 adult Arabic speaking patients with clinically diagnosed primary hypertension. Patients with secondary hypertension or complications of hypertension were excluded from the study.

Results

Fifty-seven patients (57%) were male and sixty-five (65%) were older than 40 years. Headache was the most common symptom of hypertension reported by 65% of the participants. The internal consistency of the questionnaire excluding the domain of 'Disease Identity' was 0.76 indicating satisfactory consistency. There were weak to moderate positive linear correlations (r = 0.003-0.561) between the domains of IPQ-R suggesting a reasonable discriminant validity among the domains.

Conclusion

The Arabic version of the IPQ-R for hypertensive patients is a consistent, valid, and reliable tool to be used by researchers or clinicians for assessing knowledge, beliefs, and attitudes of Arabic speaking patients with hypertension living in Saudi Arabia.

Are psychosocial variables, sleep characteristics or central pain processing prognostic factors for outcome following rotator cuff repair? A protocol for a prospective longitudinal cohort study

INTRODUCTION

Prognosis following surgical rotator cuff repair (RCR) is often established through the assessment of non-modifiable biomedical factors such as tear size. This understates the complex nature of recovery following RCR. There is a need to identify modifiable psychosocial and sleep-related variables, and to find out whether changes in central pain processing influence prognosis after RCR. This will improve our knowledge on how to optimise recovery, using a holistic rehabilitation approach.

METHODS AND ANALYSIS

This longitudinal study will analyse 141 participants undergoing usual care for first time RCR. Data will be collected 1-21 days preoperatively (T1), then 11-14 weeks (T2) and 12-14 months (T3) postoperatively. We will use mixed-effects linear regression to assess relationships between potential prognostic factors and our primary and secondary outcome measures-the Western Ontario Rotator Cuff Index; the Constant-Murley Score; the Subjective Shoulder Value; Maximal Pain (Numeric Rating Scale); and Quality of Life (European Quality of Life, 5 dimensions, 5 levels). Potential prognostic factors include: four psychosocial variables; pain catastrophising, perceived stress, injury perceptions and patients' expectations for RCR; sleep; and four factors related to central pain processing (central sensitisation inventory, temporal summation, cold hyperalgesia and pressure pain threshold). Intercorrelations will be assessed to determine the strength of relationships between all potential prognostic indicators.Our aim is to explore whether modifiable psychosocial factors, sleep-related variables and altered central pain processing are associated with outcomes pre-RCR and post-RCR and to identify them as potential prognostic factors.

ETHICS AND DISSEMINATION

The results of the study will be disseminated at conferences such as the European Pain Congress. One or more manuscripts will be published in a peer-reviewed SCI-ranked journal. Findings will be reported in accordance with the STROBE statement and PROGRESS framework. Ethical approval is granted by the Ethical commission of Canton of Zurich, Switzerland, No: ID_2018-02089 TRIAL REGISTRATION NUMBER: NCT04946149.

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.

Efficacy and Safety of Hybrid Cardiac Telerehabilitation in Patients with Hypertrophic Cardiomyopathy without Left Ventricular Outflow Tract Obstruction and Preserved Ejection Fraction—A Study Design

Hypertrophic cardiomyopathy (HCM) is the most common congenital disease increasing the risk of sudden cardiac death. For many years, HCM patients were excluded from exercise training. However, there are data showing that patients with HCM undergoing supervised exercise training could improve physical performance without serious adverse events. A project was designed as a randomized clinical trial to assess the effectiveness and safety of hybrid cardiac rehabilitation (HCR)—a combination of hospital-based cardiac rehabilitation (1 month) with a new form of home-based telemonitored cardiac rehabilitation (2 months) in HCM patients without left ventricular (LV) outflow tract obstruction and preserved systolic function. Sixty patients who fulfil the inclusion criteria have been randomly assigned (1:1) to either HCR plus usual care (training group) or usual care only (control group). The primary endpoint is a functional capacity evaluated by peak oxygen uptake (pVO2). Secondary endpoints include workload time during the cardiopulmonary exercise testing, a six-minute walk test distance, NT-pro BNP level, echocardiographic parameters of the left ventricular diastolic function (E/A, E/e’, myocardial strain rate), right ventricular systolic pressure, a gradient in the LV outflow tract, and quality of life. The tertiary analysis includes safety, acceptance and adherence to the HCR program. Our research will provide innovative data on the effectiveness and safety of hybrid cardiac rehabilitation in HCM patients without LV outflow tract obstruction and preserved systolic function.

Influence of education level on the effectiveness of pain neuroscience education: A secondary analysis of a randomized controlled trial

BACKGROUND

Current evidence supports the use of pain neuroscience education (PNE) in several chronic pain populations. However, the effects of PNE at group level are rather small and little is known about the influence of personal factors (e.g. level of education [LoE]).

OBJECTIVE

To examine whether the effectiveness of PNE differs in chronic spinal pain (CSP) patients with high LOE (at least a Bachelor's degree) versus lower educated patients.

METHOD

A total of 120 Belgian CSP patients were randomly assigned to the experimental (PNE) or control group (biomedical-focused neck/back school). Participants within each group were further subcategorized based on highest achieved LoE. ANOVA and Bonferroni post-hoc analyses were used to evaluate differences in effectiveness of the interventions between higher and lower educated participants.

RESULTS

No differences between higher and lower educated participants were identified for pain-related disability. Significant interactions (P < .05) were found for kinesiophobia and several illness perceptions components. Bonferroni post-hoc analysis revealed a significant improvement in kinesiophobia (P < .001 and P < .002, medium effect sizes) and perceived negative consequences (P < .001 and P < .008, small effect sizes) in the PNE groups. Only the higher education PNE group showed a significant improvement in perceived illness cyclicity (P = .003, small effect size). Post-treatment kinesiophobia was significant lower in the higher educated PNE group compared to the higher educated control group (p < .001).

CONCLUSION

Overall, the exploratory findings suggest no clinical meaningful differences in effectiveness of PNE between higher and lower educated people. PNE is effective in improving kinesiophobia and several aspects of illness perceptions regardless of LoE.

The Influence of Illness Perception and Mental Health on Return to Work After Carpal Tunnel Release Surgery

PURPOSE

Although multiple factors influencing return to work after a carpal tunnel release (CTR) have been identified, little is known about the influence of psychological patient factors on return to work. Therefore, this study aimed to identify the psychological factors that play a role in the return to work after a CTR surgery.

METHODS

Patients who planned to undergo a CTR were asked to fill out the Brief Illness Perception Questionnaire and the Patient Health Questionnaire before surgery to measure their illness perceptions and mental health status, respectively. Return to work was defined as the time until returning to work for 50% of normal hours and was measured using a questionnaire at 6 weeks, 3 months, and 6 months. To identify associations between nonpsychological and psychological patient factors and the return to work after CTR surgery, a Cox proportional hazards model was constructed.

RESULTS

In total, 615 patients were included in our study. Six months after surgery, 91% of the patients returned to work. For the psychological patient factors, we found that increases of 1 point on the items of worrying about carpal tunnel syndrome and having faith preoperatively in a beneficial effect of the CTR surgery were associated with hazard ratios of 0.92 (95% confidence interval, 0.88-0.96) and 1.10 (95% confidence interval, 1.02-1.19), respectively, for returning to work in the first 6 months after surgery. An increase of 1 point on the depression subscale of the Patient Health Questionnaire was associated with a hazard ratio of 0.88 (95% confidence interval, 0.78-0.99) for returning to work in the first 6 months after surgery.

CONCLUSIONS

Our study showed that multiple psychological patient factors are associated with return to work after a CTR surgery. Addressing these psychological factors before surgery might be a low-cost intervention to improve return to work after the CTR surgery.

The Persian Brief Illness Perception Questionnaire: Validation in Patients with Chronic Nonspecific Low Back Pain

BACKGROUND

Illness perceptions may influence coping behaviors as well as treatment and recovery among patients with chronic pain including low back pain (LBP). These perceptions may vary across different conditions. The Brief Illness Perception Questionnaire (BIPQ) is used as an instrument to assess the patients' perception of illness. Although the BIPQ has been previously translated into Persian, its psychometric properties have not been evaluated among patients with chronic nonspecific LBP. The aim of this study was to determine the reliability and validity of the Persian BIPQ in patients with chronic nonspecific LBP.

METHODS

116 patients with chronic nonspecific LBP with a mean (standard deviation) age of 36.4 years (10.7) participated in this cross-sectional study. Fifty patients were reexamined after 10 to 12 days for test-retest reliability. Internal consistency reliability, construct validity, concurrent criterion validity, and structural validity were evaluated. The concurrent validity was examined by using the Short Form-36 Health Survey.

RESULTS

There were no floor and ceiling effects. Cronbach's alpha for the total score was 0.90. The intraclass correlation coefficient (ICC) for test-retest reliability was 0.90. The standard error of measurement and the minimal detectable change was found to be 3.26 and 9.04, respectively. The convergent correlations confirmed the construct validity. The concurrent criterion validity was demonstrated by significant negative correlations with the SF-36. The Exploratory Factor Analysis produced the 2 factors (emotional illness representations and cognitive illness representations) with an eigenvalue >1.0 that jointly accounted for 58.86% of the total variance.

CONCLUSION

The Persian BIPQ is a reliable and 2-factor instrument and can be used for assessing illness perception in patients with chronic nonspecific LBP.

Adherence and characteristics of participants enrolled in a standardised programme of patient education and exercises for low back pain, GLA:D® Back - a prospective observational study

BACKGROUND

Low back pain is often long-lasting, and implementation of low-cost interventions to improve care and minimise its burden is needed. GLA:D® Back is an evidence-based programme consisting of patient education and supervised exercises for people with low back pain, which was implemented nationwide in primary care clinics in Denmark. To assess how the intervention was received and factors influencing adherence to the program, we aimed to evaluate participants' adherence to the intervention and identified characteristics related to the completion of GLA:D® Back. Specifically, we investigated: 1) level of attendance of participants enrolled in the programme, and 2) participant-related factors associated with low attendance.

METHODS

Primary care clinicians delivered GLA:D® Back, a standardised 10-week programme of 2 educational and 16 supervised exercise sessions, to patients with low back pain. Attendance was defined as low, medium or high based on self-reported number of attended sessions. Additional participant-reported data included demographic characteristics, pain, prognostic risk profiles, self-efficacy, illness-beliefs, function and clinician-reported physical performance tests. Results for high, medium, low, and unknown attendance were reported descriptively. Odds ratios for low attendance compared to medium/high attendance were calculated by including all baseline factors in a mixed-model logistic regression model.

RESULTS

Of 1730 participants, 52% had high, 23% medium, and 25% low levels of attendance. Level of attendance was not strongly associated with participants' individual factors, but in combination, prediction of low attendance was fair (AUC 0.77; 95% CI 0.74-0.79). The strongest indicator of low attendance was not completing the baseline questionnaire.

CONCLUSIONS

Most participants of a 10-week low back pain programme attended almost all session. Non-response to the baseline questionnaire was strongly associated with low attendance, whereas individual patient characteristics were weakly related to attendance. Not completing baseline questionnaires might be an early indicator of poor adherence in programs for people with persistent low back pain.

TRIAL REGISTRATION

A contemporary neuroscience approach compared to biomedically focused education combined with symptom-contingent exercise therapy in people with chronic whiplash associated disorders: a randomized controlled trial protocol

BACKGROUND

To address the need for a better treatment of chronic whiplash associated disorders (WAD), a contemporary neuroscience approach can be proposed.

OBJECTIVE

To examine the effectiveness of a contemporary neuroscience approach, comprising pain neuroscience education, stress management, and cognition-targeted exercise therapy versus conventional physical therapy for reducing disability (primary outcome measure) and improving quality of life and reducing pain, central sensitization, and psychological problems (secondary outcome measures) in people with chronic WAD.

METHODS

The study is a multi-center, two-arm randomized, controlled trial with 1-year follow-up and will be performed in two university-based and one regional hospital. People with chronic WAD (n=120) will be recruited. The experimental group will receive pain neuroscience education followed by cognition-targeted exercise therapy, and stress management. The control group will receive biomedically focused education followed by graded and active exercise therapy focusing on muscle endurance, strength, and flexibility, and ergonomic principles. The treatment will have a duration of 16 weeks. Functional status (Neck Disability Index) is the primary outcome measure. Secondary outcome measures include quality of life, pain, central sensitization, and psychological and socio-economic factors. In addition, electroencephalography will measure brain activity at rest and during a conditioned pain modulation paradigm. Assessments will take place at baseline, immediately post-treatment and at 6 and 12 months follow-up.

CONCLUSIONS

This study will examine whether a contemporary neuroscience approach is superior over conventional physical therapy for improving functioning, quality of life, and reducing pain, central sensitization, and psychological problems in people with chronic WAD.

The patient enablement instrument for back pain: reliability, content validity, construct validity and responsiveness

Background

Currently, there are no outcome measures assessing the ability of people with non-specific low back pain to self-manage their illness. Inspired by the ‘Patient Enablement Instrument’, we developed the Patient Enablement Instrument for Back Pain (PEI-BP). The aim of this study was to describe the development of the Patient Enablement Instrument for Back Pain (PEI-BP) and investigate content validity, construct validity, internal consistency, test–retest reliability, measurement error, responsiveness and floor and ceiling effects.

Methods

The PEI-BP consists of 6 items that are rated on a 0–10 Numeric Rating Scale. Measurement properties were evaluated using the COSMIN taxonomy and were based on three cohorts from primary care with low back pain: The content validity cohort (N = 14) which participated in semi-structured interviews, the GLA:D® Back cohort (N = 272) and the test–retest cohort (N = 37) which both completed self-reported questionnaires. For construct validity and responsiveness, enablement was compared to disability (Oswestry Disability Index), back pain beliefs (Brief Illness Perception Questionnaire), fear avoidance (Fear-Avoidance Beliefs Questionnaire—physical activity), mental health (SF-36), educational level and number of previous episodes of low back pain.

Results

The PEI-BP was found to have acceptable content validity, construct validity, reliability (internal consistency, test–retest reliability and measurement error) and responsiveness. The Smallest Detectable Change was 10.1 points illustrating that a patient would have to change more than 1/6 of the scale range for it to be a true change. A skewed distribution towards the high scores were found at baseline indicating a potentially problematic ceiling effect in the current population.

Conclusions

The PEI-BP can be considered a valid and reliable tool to measure enablement on people seeking care for non-specific LBP. Further testing of the PEI-BP in populations with more severe LBP is recommended.

Trial registration: Not applicable.

Stratified care integrated with eHealth versus usual primary care physiotherapy in patients with neck and/or shoulder complaints: protocol for a cluster randomized controlled trial

BACKGROUND

Neck and shoulder complaints are common in primary care physiotherapy. These patients experience pain and disability, resulting in high societal costs due to, for example, healthcare use and work absence. Content and intensity of physiotherapy care can be matched to a patient's risk of persistent disabling pain. Mode of care delivery can be matched to the patient's suitability for blended care (integrating eHealth with physiotherapy sessions). It is hypothesized that combining these two approaches to stratified care (referred to from this point as Stratified Blended Approach) will improve the effectiveness and cost-effectiveness of physiotherapy for patients with neck and/or shoulder complaints compared to usual physiotherapy.

METHODS

This paper presents the protocol of a multicenter, pragmatic, two-arm, parallel-group, cluster randomized controlled trial. A total of 92 physiotherapists will be recruited from Dutch primary care physiotherapy practices. Physiotherapy practices will be randomized to the Stratified Blended Approach arm or usual physiotherapy arm by a computer-generated random sequence table using SPSS (1:1 allocation). Number of physiotherapists (1 or > 1) will be used as a stratification variable. A total of 238 adults consulting with neck and/or shoulder complaints will be recruited to the trial by the physiotherapy practices. In the Stratified Blended Approach arm, physiotherapists will match I) the content and intensity of physiotherapy care to the patient's risk of persistent disabling pain, categorized as low, medium or high (using the Keele STarT MSK Tool) and II) the mode of care delivery to the patient's suitability and willingness to receive blended care. The control arm will receive physiotherapy as usual. Neither physiotherapists nor patients in the control arm will be informed about the Stratified Blended Approach arm. The primary outcome is region-specific pain and disability (combined score of Shoulder Pain and Disability Index & Neck Pain and Disability Scale) over 9 months. Effectiveness will be compared using linear mixed models. An economic evaluation will be performed from the societal and healthcare perspective.

DISCUSSION

The trial will be the first to provide evidence on the effectiveness and cost-effectiveness of the Stratified Blended Approach compared with usual physiotherapy in patients with neck and/or shoulder complaints.

Psychological Outcomes in Children and Early Adolescents With Type 1 Diabetes Following Pediatric Diabetes Summer Camp: A 3-Month Follow-Up Study

Objective: The aim of this study was to assess general psychosocial adjustment to diabetes and perceived disease management among patients with type 1 diabetes (T1D) and their parents before and after patients' participation in a diabetes summer camp. Methods: In this follow-up study, 20 children and adolescents with T1D (eight boys; mean age = 11.01 ± 0.94 years; mean diabetes duration = 3.02 ± 2.27) attending a southern Italian diabetic center, along with their parents, were assessed prior to and 3 months after the youths participated in a 1 week camp-based intervention involving didactic and interactive child-centered education and recreational activities. Patients and their parents completed measures assessing patients' quality of life and strategies employed by patients to cope with pain. Patients also completed measures evaluating their diabetes psychosocial adjustment, diabetes self-efficacy management, and illness perception; also, their parents completed measures of caregivers' perceived diabetes burden and treatment satisfaction. Youths' glycated hemoglobin (HbA1c) and standardized body mass index (z-BMI) values were also assessed. Within-subjects repeated-measures analyses of variance evaluated pre- and post-camp changes. Results: Camp attendance showed no beneficial effects on glycemic control, as indicated by HbA1c values both before (7.02%) and after (7.28%) camp being lower than 7.5%. HbA1c values were found to have increased after camp (pre-camp = 7.02%, post-camp = 7.28%; p = 0.010), but since they still fell within an acceptable range, they did not reveal clinically relevant changes in glycemic control. No substantial significant improvement in psychosocial measures was observed in children or parents (all p > 0.05). According to the parents' evaluation, social support-seeking as a patient pain-coping strategy was slightly increased (p = 0.044) after attending the camp. Conclusions: This study does not provide empirical evidence of benefits of participating in a diabetes camp for either patients or their parents. These findings suggest that healthcare providers rethink such camps as an experience for youths with T1D that actively involves parents and that includes both youth- and parent-focused psychological interventions.

Factor analysis of the Korean version of the Illness Cognition Questionnaire for adolescents with chronic illness

Aim

The purpose of this study was to examine the reliability and validity of the Korean version of the Illness Cognition Questionnaire.

Methods

A total of 237 adolescent Participants ages 13–20 years were collected from two hospitals for purposes of the study. The participants were diagnosed with blood cancer, congenital heart disease, paediatric rheumatoid arthritis, multiple sclerosis and diabetes mellitus.

Results

The Illness Cognition Questionnaire is composed of three subscales and 18 items. Exploratory factor analysis and confirmatory factor analysis were performed for all 18 items. The data used in the exploratory factor analysis were obtained from 126 adolescents with blood cancer. The data used for confirmatory factor analysis were obtained from 111 adolescents who had chronic diseases. The three‐factor model of 18 items showed general fitness close to the standard but not a very good fit.

Conclusions

This study indicated that the Korean version of the Illness Cognition Questionnaire is reasonable to use for Korean adolescents with chronic illness. The authors recommend that the meaning of Item 10 be clarified from ‘I have learned to accept the limitations imposed by my illness’ to ‘I have learned to positively accept the limitations imposed by my illness’.

What is already known about this topic?

Illness cognition is the process of evaluating the meaning of a negative event.

Illness cognition has a significant impact on patients' quality of life because it is inherently involved in long‐term stresses caused by chronic or serious illnesses.

What this paper adds?

The Korean version of the Illness Cognition Questionnaire is reliable and valid.

The Korean version of Illness Cognition Questionnaire consisted of three categories of disease awareness: acceptance, helplessness and perceived benefits

The meaning of Item 10 in the Illness Cognition Questionnaire Korean version needs to be clarified as ‘I have learned to positively accept the limitations imposed by my illness’.

The implications of this paper:

The Korean version of the Illness Cognition Questionnaire can be used for adolescent participants experiencing serious or chronic illnesses.

The Korean version of the Illness Cognition Questionnaire can be used in developing the psychological intervention for adolescents with chronic illness.

The moderating effects of pain catastrophizing on the relationship between illness perceptions and self-reported signs of central sensitization in patients with persistent pain

Two factors related to the continuation of persistent pain are pain catastrophizing and illness perceptions. Pain neuroscience education is known to positively influence both in patients with persistent pain. As the integration of pain neuroscience education in monodisciplinary physiotherapy treatments is effective, integration in transdisciplinary cognitive-behavioral treatments seems recommendable. When doing so, the moderating effect of pain catastrophizing and perceptions on treatment results have to be examined, as these provide valuable information under which conditions treatment works. A bottom-up retrospective observational study evaluated the changes in clinical outcomes, and relationships between clinical outcomes and cognitive and emotional factors in patients with persistent pain. Multiple regression analysis, PROCESS macro, explored the moderating effects of pain catastrophizing on the relationship between illness perceptions and self-reported symptoms of central sensitization. In total, 78 patients were included in the study. A correlation between pretreatment scores and change scores in illness perceptions and self-reported symptoms of central sensitization following treatment were found (resp. R-sq 0.407, F(10,99) = 0.638, P = 0.000; R-sq 0.361, F(5, 54) = 0.609, P = 0.000; and R-sq 0.314, F(4,55) = 0.560, P = 0.00), however, moderation of pain catastrophizing scores on these correlations was not found. Even though an association between changes in pain catastrophizing and illness perceptions in patients with persistent pain was found, the direction or strength between the changes in illness perceptions and changes in self-reported symptoms of central sensitization was not influenced by pretreatment scores of pain catastrophizing.

Mobile Health App (AGRIPPA) to Prevent Relapse After Successful Interdisciplinary Treatment for Patients With Chronic Pain: Protocol for a Randomized Controlled Trial

BACKGROUND

To facilitate adherence to adaptive pain management behaviors after interdisciplinary multimodal pain treatment, we developed a mobile health app (AGRIPPA app) that contains two behavior regulation strategies.

OBJECTIVE

The aims of this project are (1) to test the effectiveness of the AGRIPPA app on pain disability; (2) to determine the cost-effectiveness; and (3) to explore the levels of engagement and usability of app users.

METHODS

We will perform a multicenter randomized controlled trial with two parallel groups. Within the 12-month inclusion period, we plan to recruit 158 adult patients with chronic pain during the initial stage of their interdisciplinary treatment program in one of the 6 participating centers. Participants will be randomly assigned to the standard treatment condition or to the enhanced treatment condition in which they will receive the AGRIPPA app. Patients will be monitored from the start of the treatment program until 12 months posttreatment. In our primary analysis, we will evaluate the difference over time of pain-related disability between the two conditions. Other outcome measures will include health-related quality of life, illness perceptions, pain self-efficacy, app system usage data, productivity loss, and health care expenses.

RESULTS

The study was approved by the local Medical Research Ethics Committee in October 2019. As of March 20, 2020, we have recruited 88 patients.

CONCLUSIONS

This study will be the first step in systematically evaluating the effectiveness and efficiency of the AGRIPPA app. After 3 years of development and feasibility testing, this formal evaluation will help determine to what extent the app will influence the maintenance of treatment gains over time. The outcomes of this trial will guide future decisions regarding uptake in clinical practice.

A Systematic Review of the Instruments Used for Evaluating Causal Beliefs and Perceived Heart Risk Factors

Background: The etiologies and causal beliefs of heart disease are considered one of the 5 dimensions of health self-regulatory model. Thus, the present study aimed to review the literature and screen the appropriate tools for evaluating the causal beliefs and perceived heart risk factors (PHRFs). Methods: The review samples encompassed all published articles from 1992 to March 2017. A systematic search was conducted across 6 databases: the Web of Science, Scopus, Medline, EBSCO, ProQuest, PsycINFO, and Google Scholar. The qualitative evaluation of the articles was examined using the checklists of the Critical Appraisal Skills Programme (CASP) by 2 independent investigators. After the application of the criteria for inclusion in the study, 22 studies were obtained according to the PRISMA guidelines. Results: A total of 10 504 (50.5% male) patients at an average age of 57.85±10.75 years participated in 22 studies under review. The results of the systematic review showed that 22 tools were available to measure PHRFs. The instruments were categorized into 4 groups of valid scales (6 studies), invalid questionnaires (6 studies), checklists (3 studies), and open-ended single items (7 studies). Only 23.2% of the measuring instruments were sufficiently valid. Conclusion: The results of this systematic review showed that a limited number of valid tools were available to measure PHRFs. Considering the importance of studying cardiac patients' perception of the etiology of disease and the paucity of standards and valid grading scales, it seems necessary to design and provide tools with broader content that can cover all aspects of patients' beliefs.

Questionnaire on Perception of Threat from COVID-19

The ravages caused by the disease known as COVID-19 has led to a worldwide healthcare and social emergency requiring an effective combined effort from everyone to reduce contagion. Under these circumstances, the perception of the disease is going to have a relevant role in the individual’s psychological adjustment. However, at the present time there is no validated instrument for evaluating adult perception of threat from COVID-19. Considering the importance of perception or representation of the disease in a state of social alert, our study intended to validate an instrument measuring the psychological process of the disease caused by the coronavirus (COVID-19). In view of the above, this study evaluated the factor structure and reliability of the version of the Illness Perception Questionnaire (IPQ) for COVID-19 in a sample of adults. The sample consisted of 1014 Spanish adults (67.2% women and 32.8% men). The exploratory and confirmatory factor analyses supported a unidimensional model of the scale, which was the one that showed the best fit and explained 43.87% of the variance. This brief version has adequate psychometric properties and may be used to evaluate the perception of threat from COVID-19 in an adult Spanish population. The validation of this instrument contributes to progress in representation of COVID-19 in our culture.

Psychometric properties of the questionnaire on threat perception of chronic illnesses in pediatric patients

OBJECTIVE

the objective of the study was to assess the psychometric properties of the Brief Illness Perception Questionnaire in a sample of adolescents with chronic endocrine or pneumological conditions and to analyze the dimensionality and reduce the scale elaborating scales by sex and medical diagnosis.

METHOD

we evaluated 510 patients aged 9-16 years using the Brief Illness Perception Questionnaire and the Hospital Anxiety and Depression Scale. We carried out tests of reliability, construct and criterion validity and a comparison of means based on the diagnosis and socio-demographic variables. The reliability and validity analyses showed adequate psychometric properties for this scale, with better results obtained for a single dimension after eliminating 3 items.

RESULTS

adolescents with type 1 diabetes and girls were found to have an increased threat perception of their illness. Anxiety/depression was positively associated with the perception of illness.

CONCLUSION

this questionnaire is a useful and practical tool for evaluating adjustment to illness in pediatric patients.

Brazilian version of the Self-Estimated Functional Inability because of Pain questionnaire for musculoskeletal injuries relating to dance and sport: translation and cross-cultural adaptation

BACKGROUND

Self-Estimated Functional Inability because of Pain (SEFIP) is a questionnaire specifically designed to measure musculoskeletal pain or discomfort.

OBJECTIVE

To perform translation and cross-cultural adaptation of the SEFIP for dancers (SEFIP-dance), for use in Brazilian Portuguese. In addition, as a secondary objective, we adapted the translated version of SEFIP-dance for use among athletes or exercise practitioners (SEFIP-sport).

DESIGN AND SETTING

Questionnaire translation and cross-cultural adaptation study conducted at a public university.

METHODS

The Brazilian version of the SEFIP-dance questionnaire was developed following the processes of translation (involving two translators with Brazilian Portuguese as their mother tongue and fluency in English), backtranslation (involving two translators with English as their mother tongue and fluency in Brazilian Portuguese), committee review and pre-testing. SEFIP-sport was developed following the processes of content and face validation.

RESULTS

SEFIP-dance was applied to 30 dancers, of mean age 22.38 years (standard deviation [SD] = 3.41), among whom 14 were men (46.66%). The participants understood 100% of the SEFIP-dance items and alternatives. SEFIP-sport was applied to 30 athletes or physical exercise practitioners, of mean age 25.09 years (SD = 8.93), among whom 25 were men (86.33%). The participants understood 100% of the -SEFIP-sport items and alternatives.

CONCLUSION

The Brazilian Portuguese versions of SEFIP-dance, translated and cross-culturally adapted for dancers, and SEFIP-sport, adapted for athletes or physical exercise practitioners, were shown to have adequate levels of understanding.

Deciphering programs for optimal self-management of persistent musculoskeletal-related pain and disability - Clinical implications for PTs

The prolonged disability associated with musculoskeletal (MSK) pain represents an enormous health burden, for individuals as well as society. Promoting pain and disability management for patients with persistent MSK-related conditions can be very challenging for rehabilitation professionals. These often-complex conditions require the adoption of a biopsychosocial perspective in order to assess and address a vast array of potential factors affecting the patient. Fortunately, a self-management (SM) approach has been deemed effective in enhancing patients' control over their symptoms and disabilities. However, given the many different existing SM approaches, rehabilitation professionals would benefit from a clearer definition of SM and a better understanding of the basics of a SM program in order to facilitate their patients' development of SM skills, as this can lead to better outcomes. This narrative review explores the various components of an intervention program intended to facilitate patients' SM of their symptoms and disabilities resulting from a persistent MSK condition. It does so by drawing on a body of published work on pain and disability management, conceptual frameworks underlying SM programs, essential skills associated with optimal SM, and examples from the persistent low back pain (LBP) literature.

A network analysis of the Brief Illness Perception Questionnaire in patients with rheumatic diseases and human immunodeficiency virus infection

Objective: To examine the construct of illness perception (IP) as measured by the Brief Illness Perception Questionnaire (BIPQ) using network analysis in patients with rheumatic diseases (RD) and with human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS).Design: Cross-sectional and multicentre survey.Main Outcome Measures: The BIPQ and the Hospital Anxiety and Depression Scale.Results: BIPQ network structures did not differ between patients with RD and HIV/AIDS. Community analysis identified two clusters: one comprised consequences, timeline, identity, concern and emotional response; and the other consisted of personal control, treatment control and comprehensibility. Centrality indices indicate that concern, consequences and emotional response are central dimensions of the BIPQ. Directed acyclic graph analysis revealed that concern was a dominant network item, activating emotional response, consequences, identity and comprehensibility. Emotional response and consequences were bridging items linking IP to anxiety and depression.Conclusion: Perceived impact of illness on life and emotion and illness concern are central dimensions of the BIPQ that link IP to anxiety and depression in patients with RD and HIV/AIDS. Care of patients with RD and HIV/AIDS may benefit from addressing IP, particularly concern, emotional response and consequences to prevent clinical anxiety and depression.

Multidimensional screening for predicting pain problems in adults: a systematic review of screening tools and validation studies

Screening tools allowing to predict poor pain outcomes are widely used. Often these screening tools contain psychosocial risk factors. This review (1) identifies multidimensional screening tools that include psychosocial risk factors for the development or maintenance of pain, pain-related distress, and pain-related disability across pain problems in adults, (2) evaluates the quality of the validation studies using Prediction model Risk Of Bias ASsessment Tool (PROBAST), and (3) synthesizes methodological concerns. We identified 32 articles, across 42 study samples, validating 7 screening tools. All tools were developed in the context of musculoskeletal pain, most often back pain, and aimed to predict the maintenance of pain or pain-related disability, not pain-related distress. Although more recent studies design, conduct, analyze, and report according to best practices in prognosis research, risk of bias was most often moderate. Common methodological concerns were identified, related to participant selection (eg, mixed populations), predictors (eg, predictors were administered differently to predictors in the development study), outcomes (eg, overlap between predictors and outcomes), sample size and participant flow (eg, unknown or inappropriate handling of missing data), and analysis (eg, wide variety of performance measures). Recommendations for future research are provided.

Explaining pain following cancer: a practical guide for clinicians

BACKGROUND

Pain is one of the most prevalent and debilitating symptom following cancer treatment.

OBJECTIVES

This paper entails a practical guide for clinicians willing to apply pain neuroscience education (PNE) in this specific population, or clinical researchers willing to examine the effects of PNE in patients suffering from pain following cancer.

RESULTS

Patient-specific information (i.e. beliefs, cognitions, pain memories, social factors) as well as identification of the dominant pain mechanism are needed to tailor the education to the specific needs and beliefs of the patient. Therapists require an in-depth understanding of pain mechanisms, the skills to explain to their patients various pain mechanisms, specific communication skills (e.g. Socratic-style dialogof education) and experience with current evidence-based biopsychosocially-driven pain management strategies for successful implementation of PNE in the clinic. Rather than purely focusing on the biomedical characteristics of pain following cancer (e.g., tissue damage due to past cancer treatment), PNE implies teaching patients about the underlying biopsychosocial mechanisms of pain. Its application is backed-up by mounting evidence supporting the effectiveness of PNE in non-cancer pain populations, and a pilot study in patients having pain following cancer.

CONCLUSION

PNE is a potential solution to improve pain outcome in cancer survivors. Further research using sufficiently powered and well-designed randomized clinical trials should be conducted to examine the potential of PNE in patients having pain following cancer.

Does illness perception associate with disease symptoms in Behçet's disease?

This study aims to assess the relationship between illness perception and disease course and symptoms in Behçet disease (BD). One hundred ten consecutive BD patients (F/M 50/60, mean age 38.5 ± 9.88 years) and 57 patients with Psoriasis as a disease control group (F/M 28/29, mean age 48.12 ± 15.52) are included in this cross-sectional study. Illness perception is evaluated using a revised version of the Illness Perception Questionnaire (IPQ-R). In IPQ-R, the identity score reflecting the number of symptoms is higher in BD patients with musculoskeletal involvement than the others (6.77 ± 2.91 vs. 5.08 ± 3.3, respectively, p = 0.007). The consequences score for musculoskeletal involvement (19.52 ± 7.03) and timeline (acute/chronic) score for eye involvement (26.67 ± 4.32) are also higher compared to patients without them (16.37 ± 5.82 and 22.09 ± 8.68) (p = 0.011 and p = 0.038), reflecting negative beliefs about the illness. The score of psychological attribution is higher in patients with psoriasis than BD (p = 0.039), whereas the other subgroup scores are lower in patients with psoriasis compared to those of BD (p < 0.05). This study provides a patient's perspective in the disease management process of BD using the IPQ-R questionnaire. A patient's own personal beliefs and emotional responses to their symptoms might affect the outcome measures, especially with musculoskeletal symptoms and eye involvement in BD. However, psychological attribution is found to be a prominent issue in psoriasis.

GLA:D® Back: group-based patient education integrated with exercises to support self-management of persistent back pain - feasibility of implementing standardised care by a course for clinicians

BACKGROUND

Clinical guidelines for management of low back pain (LBP) are not routinely implemented in practice, and guidelines rarely offer tools for implementation. Therefore, we developed GLA:D® Back, a standardised intervention of patient education and supervised exercises. This pilot study tested the feasibility of implementing GLA:D Back in clinical practice in Denmark by delivering a course for physiotherapists and chiropractors. It should further inform the planning of an implementation-effectiveness study using a pre-post group design alongside nation-wide implementation.

METHODS

Thirty-one clinicians from nine clinics participated. Feasibility of implementation was evaluated in terms of adoption and through focus group interviews and a feedback meeting. Patient-level data, including pain, disability, and pain enablement, were collected from (1) LBP patients visiting the clinics during a pre-specified 2-week period 2 months prior to clinicians attending the GLA:D Back course (n = 84), (2) LBP patients consulting during a 2-week period 2 months after the course (n = 77), and (3) those enrolled in GLA:D Back during 4 months after implementation (n = 89). Patient data were collected at baseline and at 4 months.

RESULTS

Clinicians' evaluations of the course were positive and resulted in several modifications. The clinical intervention was adopted by all test sites. Most patient characteristics were similar across groups. Patients mainly had persistent LBP (73% > 3 months) and most had been treated for more than 4 weeks at inclusion. Patients in GLA:D Back were more often retired (30% vs. 16% before implementation) and at high risk of poor prognosis (25% vs. 13%). Procedures for data collection were feasible, and outcomes after implementation, especially with GLA:D Back, were as good as or better than before implementation. Recruiting patients and achieving comparable pre- and post-groups was difficult.

CONCLUSIONS

Implementation of the GLA:D Back clinical intervention in Danish primary care physiotherapy and chiropractic clinics was feasible through a 2-day clinician course. Both clinicians and patients were satisfied with the programme, and patient-reported outcomes were slightly better than outcomes in patients registered before implementation. It was not deemed possible to conduct an implementation-effectiveness trial as part of a nation-wide implementation.

GLA:D® Back: implementation of group-based patient education integrated with exercises to support self-management of back pain - protocol for a hybrid effectiveness-implementation study

BACKGROUND

Reassuring patient education and exercise therapy are widely recommended interventions for back pain in clinical guidelines. However, many patients are offered non-guideline endorsed options, and strategies for effective implementation of guideline-based care have not yet been developed. This protocol outlines the evaluation of a strategy for nationwide implementation of standardised patient education and exercise therapy for people with persistent or recurrent back pain in a hybrid implementation-effectiveness design. The strategy and the evaluation were planned using the framework of the Behaviour Change Wheel.

METHODS

The main activity of the implementation strategy is a two-days course for physiotherapists and chiropractors in delivering patient education and exercise therapy that is aimed at supporting patient self-management. This comes with ready-to-use patient education materials and exercise programs. The clinical intervention is a group-based program consisting of two sessions of patient education and 8 weeks of supervised exercises. The program uses a cognitive-behavioural approach and the aim of the exercise component is to restore the patient's ability and confidence to move freely. The implementation process is evaluated in a dynamic process monitoring the penetration, adoption and fidelity of the clinical intervention. The clinical intervention and potential effect mechanisms will be evaluated at the patient-level using measures of knowledge, skills, beliefs, performance, self-efficacy and success in self-management. The education of clinicians will be evaluated via clinician-level outcomes, including the Pain Attitudes and Beliefs Scale, the Practitioner Confidence Scale, and the Determinants of Implementation Behaviour Questionnaire. Effects at a national level will be investigated via data from national registries of health care utilisation and sick-leave.

DISCUSSION

This implementation-effectiveness study is designed to evaluate the process of implementing an evidence-based intervention for back pain. It will inform the development of strategies for implementing evidence-based care for musculoskeletal pain conditions, it will enhance the understanding of mechanisms for developing patient self-management skills, and it will demonstrate the outcomes that are achievable in everyday clinical practice.

Patients' drawings of their asthma: adding qualitative specificity to a quantitative measure of illness perceptions

Objective: Patients' perceptions about their asthma can influence behavior, coping and outcomes. Previous studies have also identified that patients' views can differ significantly to that of healthcare professionals. Enhancing current understanding of patients' perceptions can assist in reducing this mismatch. We aimed to utilize the medium of drawings to add qualitative specificity and depth to a quantitative measure of illness perceptions exploring patients' perspectives of their asthma. Methods: Eighteen adults with asthma completed the Brief Illness Perception Questionnaire (BIPQ) and participated in a drawing activity. Analysis was based on the participants' transcribed descriptions of their drawing. A coding approach was used to map the data according to the BIPQ items. Results: The drawings and subsequent discussions specified the "what," the "how," and the "why" of the experience of living with asthma. Prominent emotional and social elements emerged, with evocative images coupled with expressive and profound language. Use of drawing also revealed additional representations which were outside of the BIPQ scope. Conclusions: Using qualitative methods to analyze a novel approach to understanding illness perceptions provided insight into how asthma affects patients' lives personally.

GLA:D® Back group-based patient education integrated with exercises to support self-management of back pain - development, theories and scientific evidence

BACKGROUND

Clinical guidelines recommend that people with back pain be given information and education about their back pain, advice to remain active and at work, and exercises to improve mobility and physical activity. Guidelines, however, rarely describe how this is best delivered. The aim of this paper is to present the development, theories, and underlying evidence for 'GLA:D Back' - a group education and exercise program that translates guideline recommendations into a clinician-delivered program for the promotion of self-management in people with persistent/recurrent back pain.

METHODS

GLA:D Back, which included a rationale and objectives for the program, theory and evidence for the interventions, and program materials, was developed using an iterative process. The content of patient education and exercise programs tested in randomised trials was extracted and a multidisciplinary team of expert researchers and clinicians prioritised common elements hypothesised to improve back pain beliefs and management skills. The program was tested on eight people with persistent back pain in a university clinic and 152 patients from nine primary care physiotherapy and chiropractic clinics. Following feedback from the clinicians and patients involved, the working version of the program was created.

RESULTS

Educational components included pain mechanisms, pain modulation, active coping strategies, imaging, physical activity, and exercise that emphasised a balance between the sum of demands and the individual's capacity. These were operationalised in PowerPoint presentations with supporting text to aid clinicians in delivering two one-hour patient education lectures. The exercise program included 16 supervised one-hour sessions over 8 weeks, each comprising a warm-up section and eight types of exercises for general flexibility and strengthening of six different muscle groups at four levels of difficulty. The aims of the exercises were to improve overall back fitness and, at the same time, encourage patients to explore variations in movement by incorporating education content into the exercise sessions.

CONCLUSION

From current best evidence about prognostic factors in back pain and effective treatments for back pain, research and clinical experts developed a ready-to-use structured program - GLA:D® Back - to support self-management for people with persistent/recurrent back pain.

The Association of Illness Perception and Prognosis for Pain and Physical Function in Patients With Noncancer Musculoskeletal Pain: A Systematic Literature Review

BACKGROUND

In the literature, illness perceptions have been reported to be important psychological factors associated with pain intensity and physical function in individuals with musculoskeletal pain.

OBJECTIVE

To assess the relationship of illness perceptions with pain intensity and physical function in individuals with noncancer musculoskeletal pain.

METHODS

In this systematic review, relevant literature databases, including PubMed, Embase, PsycINFO, CINAHL, and SPORTDiscus, were searched from inception through December 12, 2017. Two authors (E.D.R. and H.W.) independently performed the search procedures, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the A MeaSurement Tool to Assess systematic Reviews guidelines, and the risk-of-bias assessment, using the QUality In Prognosis Studies tool. A qualitative best-evidence synthesis was performed.

RESULTS

A total of 26 articles were included in the review. There were 11 cross-sectional studies concerning associations of illness perceptions with pain intensity and 11 cross-sectional studies of associations of illness perceptions with physical function. For the prognosis of pain intensity by illness perceptions, the authors found 4 longitudinal studies, and for the prognosis of physical function by illness perceptions, the authors found 12 longitudinal studies. All studies except 1 had high risk of bias. Across 15 cross-sectional studies on 9 different musculoskeletal conditions, the researchers found limited to moderate evidence for a consistent direction of the relationship of illness perceptions with pain intensity and physical function. Higher maladaptive illness perceptions imply stronger pain intensity and more limitation in physical function. Evidence in longitudinal studies is lacking, especially on pain.

CONCLUSION

There is limited to moderate evidence for the cross-sectional relationship between illness perceptions and various musculoskeletal conditions. The prognostic value, however, remains unclear. Future research is recommended to investigate the longitudinal relationship between illness perception domains and outcomes in greater detail. J Orthop Sports Phys Ther 2018;48(10):789-800.

Psychometric evaluation of the Chinese version of the revised illness perception questionnaire for breast cancer-related lymphedema

The aim of this study was to modify and test the Chinese version of the Revised Illness Perception Questionnaire to measure the illness perception of breast cancer-related lymphedema among breast cancer survivors. Before the investigation, identity and causal subscales were modified and the wording of the remaining scales was also adjusted. The psychometric properties of this instrument was evaluated using the technique of explore and confirmatory factor analysis. Data from 203 breast cancer survivors was entered into factor analysis. Five causal factors were extracted after removing one item, accounting for 68.02% of the variance in total. An acceptable fit with the data for the proposed seven-factor model was obtained after eliminating three items and resetting seven error covariances. The Cronbach's α values and composite reliability coefficients were acceptable. This measurement is reliable and valid for measuring illness perceptions of breast cancer-related lymphedema in Chinese breast cancer survivors. It could be helpful for further studies that examine the effect of illness perceptions on health-related behaviours, such as lymphedema risk-reduction behaviours in the Chinese cultural context.
