Factor structure and measurement invariance of the Health Education Impact Questionnaire: Does the subjectivity of the response perspective threaten the contextual validity of inferences?

Influence of central aspects of pain on self-management in people with chronic low back pain

OBJECTIVE

This observational study investigated whether central aspects of pain are associated with self-management domains in individuals with chronic low back pain (CLBP) undertaking a pain management program.

METHODS

Individuals with CLBP provided pain sensitivity and self-management data at baseline (n = 97) and 3-months (n = 87). Pressure pain detection threshold (PPT) at the forearm, temporal summation (TS) and conditioned pain modulation (CPM), Widespread Pain Index (WPI), and a Central Aspects of Pain factor (CAPf) were considered as central aspects of pain. Self-management was measured using the 8 domains of the Health Education Impact Questionnaire, as well as Pain Self Efficacy and Health Care Utilisation questionnaires.

RESULTS

PPT, CPM, WPI and CAPf predicted worse performance in several self-management domains at 3-months (r = 0.21 to 0.54, p < 0.05 overall). In multivariable regression models (adjusted for baseline scores of self-management, depression, catastrophization, pain and fatigue) low PPT, high TS, and high CAPf at baseline predicted poorer self-management at 3 months (R2 =0.14 to 0.52, β = -0.37 to 0.35, p < 0.05).

CONCLUSIONS

Central aspects of pain are associated with impaired self-management, over and above effects of pain intensity, fatigue, depression and catastrophizing.

PRACTICE IMPLICATIONS

Treatments that target central aspects of pain might help improve self-management in people with CLBP.

Predictors of self-management in patients with chronic low back pain: a longitudinal study

BACKGROUND

Self-management (SM) is a key recommended strategy for managing chronic low back pain (CLBP). However, SM programmes generate small to moderate benefits for reducing pain and disability in patients with CLBP. The benefits of the SM programme can potentially be optimised by identifying specific subgroups of patients who are the best responders. To date, no longitudinal study has examined the predictive relationships between SM and biopsychosocial factors in patients with CLBP. The aim was to determine whether biopsychosocial factors predict SM and its change over time in patients with CLBP.

METHODS

In this multi-centre longitudinal cohort study, we recruited 270 working-age patients with CLBP (mean age 43.74, 61% female) who consulted outpatient physiotherapy for their CLBP. Participants completed self-reported validated measures of pain intensity, disability, physical activity, kinesiophobia, catastrophising, depression and SM at baseline and six months. SM constructs were measured using eight subscales of the Health Education Impact Questionnaire (heiQ), including Health Directed Activity (HDA), Positive and Active Engagement in Life (PAEL), Emotional Distress (ED), Self-Monitoring and Insight (SMI), Constructive Attitudes and Approaches (CAA), Skill and Technique Acquisition (STA), Social Integration and Support (SIS) and Health Service Navigation (HSN). Data were analysed using General Linear Model (GLM) regression.

RESULTS

Physical activity and healthcare use (positively) and disability, depression, kinesiophobia, catastrophising (negatively) predicted (p < 0.05, R² 0.07-0.55) SM constructs at baseline in patients with CLBP. Baseline depression (constructs: PAEL, ED, SMI, CAA and STA), kinesiophobia (constructs: CAA and HSN), catastrophising (construct: ED), and physical disability (constructs: PAEL, CAA and SIS) negatively predicted a range of SM constructs. Changes over six months in SM constructs were predicted by changes in depression, kinesiophobia, catastrophising, and physical activity (p < 0.05, R² 0.13-0.32).

CONCLUSIONS

Self-reported disability, physical activity, depression, catastrophising and kinesiophobia predicted multiple constructs of SM measured using the heiQ subscales in working-age patients with CLBP. Knowledge of biopsychosocial predictors of SM may help triage patients with CLBP into targeted pain management programmes.

Effectiveness of a brief positive skills intervention to improve psychological adjustment in patients with end-stage kidney disease newly initiated on haemodialysis: protocol for a randomised controlled trial (HED-Start)

INTRODUCTION

Initiation onto haemodialysis is a critical transition that entails multiple psychosocial and behavioural demands that can compound mental health burden. Interventions guided by self-management and cognitive-behavioural therapy to improve distress have been variably effective yet are resource-intensive or delivered reactively. Interventions with a focus on positive affect for patients with end-stage kidney disease are lacking. This study will seek (1) to develop a positive life skills intervention (HED-Start) combining evidence and stakeholder/user involvement and (2) evaluate the effectiveness of HED-Start to facilitate positive life skills acquisition and improve symptoms of distress and adjustment in incident haemodialysis patients.

METHODS AND ANALYSIS

This is a single/assessor-blinded randomised controlled trial (RCT) to compare HED-Start to usual care. In designing HED-Start, semistructured interviews, a codesign workshop and an internal pilot will be undertaken, followed by a two-arm parallel RCT to evaluate the effectiveness of HED-Start. A total of 148 incident HD patients will be randomised using a 1:2 ratio into usual care versus HED-Start to be delivered in groups by trained facilitators between January 2021 and September 2022. Anxiety and depression will be the primary outcomes; secondary outcomes will be positive and negative affect, quality of life, illness perceptions, self-efficacy, self-management skills, benefit finding and resilience. Assessments will be taken at 2 weeks prerandomisation (baseline) and 3 months postrandomisation (2 weeks post-HED-Start completion). Primary analyses will use an intention-to-treat approach and compare changes in outcomes from baseline to follow-up relative to the control group using mixed-effect models.

ETHICS AND DISSEMINATION

Ethics approval was obtained from Nanyang Technological University Institutional Review Board (IRB-2019-01-010). Written informed consent will be obtained before any research activities. Trial results will be disseminated via publications in peer-reviewed journals and conference presentations and will inform revision(s) in renal health services to support the transition of new patients to haemodialysis.

Artificial intelligence: A rapid case for advancement in the personalization of Gynaecology/Obstetric and Mental Health care

To evaluate and holistically treat the mental health sequelae and potential psychiatric comorbidities associated with obstetric and gynaecological conditions, it is important to optimize patient care, ensure efficient use of limited resources and improve health-economic models. Artificial intelligence applications could assist in achieving the above. The World Health Organization and global healthcare systems have already recognized the use of artificial intelligence technologies to address 'system gaps' and automate some of the more cumbersome tasks to optimize clinical services and reduce health inequalities. Currently, both mental health and obstetric and gynaecological services independently use artificial intelligence applications. Thus, suitable solutions are shared between mental health and obstetric and gynaecological clinical practices, independent of one another. Although, to address complexities with some patients who may have often interchanging sequelae with mental health and obstetric and gynaecological illnesses, 'holistically' developed artificial intelligence applications could be useful. Therefore, we present a rapid review to understand the currently available artificial intelligence applications and research into multi-morbid conditions, including clinical trial-based validations. Most artificial intelligence applications are intrinsically data-driven tools, and their validation in healthcare can be challenging as they require large-scale clinical trials. Furthermore, most artificial intelligence applications use rate-limiting mock data sets, which restrict their applicability to a clinical population. Some researchers may fail to recognize the randomness in the data generating processes in clinical care from a statistical perspective with a potentially minimal representation of a population, limiting their applicability within a real-world setting. However, novel, innovative trial designs could pave the way to generate better data sets that are generalizable to the entire global population. A collaboration between artificial intelligence and statistical models could be developed and deployed with algorithmic and domain interpretability to achieve this. In addition, acquiring big data sets is vital to ensure these artificial intelligence applications provide the highest accuracy within a real-world setting, especially when used as part of a clinical diagnosis or treatment.

Assessing health empowerment - Brazilian cross-cultural adaptation and validity testing of the health education impact questionnaire (heiQ) among people with chronic low back pain

BACKGROUND

There is no patient reported outcome measure available in Brazilian Portuguese to comprehensively assess outcomes following administration of patient education programs for people with chronic conditions.

OBJECTIVE

To describe the cross-cultural adaptation and measurement properties of the Brazilian Portuguese version of the Health Education Impact Questionnaire (heiQ), a multidimensional questionnaire designed for the evaluation of patient education programs, which was tested in people with chronic low back pain (LBP).

METHODS

One hundred thirty-seven individuals with non-specific chronic LBP (age: 38.7 ± 13.2) were enrolled in the study. The translation was performed according to international standards. Intraclass correlation coefficient (ICC) was used to assess test-retest reliability, Cronbach's α to assess internal consistency, Pearson rank correlation to compare the heiQ scales with comparator scales, and confirmatory factor analysis (CFA) for structural validity.

RESULTS

The test-retest analysis yielded ICC values ranging from 0.75 to 0.91. Cronbach's alphas for the seven scales ranged from 0.70 to 0.89. Significant correlations between affective and general health constructs and the heiQ scales (72%) were observed. For the majority of the scales, the CFA fit statistics showed to be good to excellent.

CONCLUSION

Overall, the Brazilian Portuguese version of the heiQ showed acceptable reliability, internal consistency, construct validity, and structural validity in individuals with chronic LBP. The heiQ scales may serve as direct outcomes to assess education and self-management programs for the Brazilian Portuguese speaker population.

Pilot randomised clinical trial of an eHealth, self-management support intervention (iVERVE) for stroke: feasibility assessment in survivors 12-24 months post-event

BACKGROUND

Electronic communication is used in various populations to achieve health goals, but evidence in stroke is lacking. We pilot tested the feasibility and potential effectiveness of a novel personalised electronic self-management intervention to support person-centred goal attainment and secondary prevention after stroke.

METHODS

A phase I, prospective, randomised controlled pilot trial (1:1 allocation) with assessor blinding, intention-to-treat analysis, and a process evaluation. Community-based survivors of stroke were recruited from participants in the Australian Stroke Clinical Registry (AuSCR) who had indicated their willingness to be contacted for research studies. Inclusion criteria include 1-2 years following hospital admission for stroke and living within 50 km of Monash University (Melbourne). Person-centred goals were set with facilitation by a clinician using a standardised template. The intervention group received electronic support messages aligned to their goals over 4 weeks. The control group received only 2-3 electronic administrative messages. Primary outcomes were study retention, goal attainment (assessed using Goal Attainment Scaling method) and satisfaction. Secondary outcomes were self-management (Health Education Impact Questionnaire: 8 domains), quality of life, mood and acceptability.

RESULTS

Of 340 invitations sent from AuSCR, 73 responded, 68 were eligible and 57 (84%) completed the baseline assessment. At the goal-setting stage, 54/68 (79%) were randomised (median 16 months after stroke): 25 to intervention (median age 69 years; 40% female) and 29 to control (median age 68 years; 38% female). Forty-five (83%) participants completed the outcome follow-up assessment. At follow-up, goal attainment (mean GAS-T score ≥ 50) in the intervention group was achieved for goals related to function, participation and environment (control: environment only). Most intervention participants provided positive feedback and reported that the iVERVE messages were easy to understand (92%) and assisted them in achieving their goals (77%). We found preliminary evidence of non-significant improvements between the groups for most self-management domains (e.g. social integration and support: β coefficient 0.34; 95% CI - 0.14 to 0.83) and several quality-of-life domains in favour of the intervention group.

CONCLUSION

These findings support the need for further randomised effectiveness trials of the iVERVE program to be tested in people with new stroke.

Questionnaire validation practice within a theoretical framework: a systematic descriptive literature review of health literacy assessments

OBJECTIVE

Validity refers to the extent to which evidence and theory support the adequacy and appropriateness of inferences based on score interpretations. The health sector is lacking a theoretically-driven framework for the development, testing and use of health assessments. This study used the Standards for Educational and Psychological Testing framework of five sources of validity evidence to assess the types of evidence reported for health literacy assessments, and to identify studies that referred to a theoretical validity testing framework.

METHODS

A systematic descriptive literature review investigated methods and results in health literacy assessment development, application and validity testing studies. Electronic searches were conducted in EBSCOhost, Embase, Open Access Theses and Dissertations and ProQuest Dissertations. Data were coded to the Standards' five sources of validity evidence, and for reference to a validity testing framework.

RESULTS

Coding on 46 studies resulted in 195 instances of validity evidence across the five sources. Only nine studies directly or indirectly referenced a validity testing framework. Evidence based on relations to other variables is most frequently reported.

CONCLUSIONS

The health and health equity of individuals and populations are increasingly dependent on decisions based on data collected through health assessments. An evidence-based theoretical framework provides structure and coherence to existing evidence and stipulates where further evidence is required to evaluate the extent to which data are valid for an intended purpose. This review demonstrates the use of the Standards' theoretical validity testing framework to evaluate sources of evidence reported for health literacy assessments. Findings indicate that theoretical validity testing frameworks are rarely used to collate and evaluate evidence in validation practice for health literacy assessments. Use of the Standards' theoretical validity testing framework would improve evaluation of the evidence for inferences derived from health assessment data on which public health and health equity decisions are based.

Evaluation of the Health Education Impact Questionnaire (heiQ), a Self-Management Skill Assessment Tool, in Italian Chronic Patients

Background

The Health Education Impact Questionnaire (heiQ) aims to evaluate eight self-management skills in people with chronic conditions. Knowledge about the relations between these self-management skills and different quality of life (QoL) outcomes has received little attention. It is also important to provide further evidence on its properties in non-English healthcare contexts, as the questionnaire is being used in cross-cultural research. Furthermore, in the Italian healthcare context, the relationship between the medical staff and the patients remains asymmetrical, with the latter having the role of passive recipients of medical prescriptions and services. The current study provided further evidence about the psychometric properties of the heiQ among Italian people with chronic conditions, specifically by assessing the factor structure, reliability, convergent/divergent and criterion validity (ie, the specific contribution of each of the self-management skills to QoL outcomes).

Methods

Two hundred ninety-nine individuals with a chronic condition (mean age = 61.4 years, 50% females) completed the heiQ and the Medical Outcomes Study-Short Form (MOS SF-36). Confirmatory factor analyses, Composite Reliability Indices (CRI), bivariate correlations and linear regression analyses were computed.

Results

A model with 8 correlated factors showed good fit, in a similar way to previous studies. CRI values were acceptable to good for all the subscales. Associations between some of the heiQ subscales and some of the MOS SF-36 subscales supported criterion validity. In particular, it was confirmed by the moderate associations between the constructive attitudes and approaches subscale and the MOS SF-36 vitality and perceived mental health and by the moderate correlations between the health directed activities subscale and the MOS SF-36 Vitality. In linear regressions, higher emotional distress predicted higher physical and mental QoL, while higher mental QoL was also associated with stronger constructive attitudes and approaches.

Conclusion

The heiQ has robust properties across translations and it can also be used routinely in Italian healthcare contexts. The evidence that all the other self-management skills did not predict either physical or mental QoL could suggest that the self-management model of chronic diseases is still not sufficiently developed in the Italian context, where patients are passive recipients of medical instructions.

Italian validation of the health education impact questionnaire (heiQ) in people with chronic conditions

BACKGROUND

The health education impact Questionnaire (heiQ) measures eight self-management skills in people with chronic conditions. It seems to be important to provide cross-cultural evidence on its properties in non-English healthcare contexts. The present study assessed the psychometric properties of the heiQ in Italian adults with chronic conditions.

METHODS

Two hundred ninety-nine individuals with a chronic condition (mean age = 61.4 years, 50.16% females) completed the heiQ and the Medical Outcomes Study-Short Form (SF-36). Confirmatory factor analyses, Composite Reliability Indices, and bivariate correlations were performed.

RESULTS

Structural validity based on 8 correlated factors with good fit was in line with previous research. Concurrent validity was confirmed, as shown by moderate associations between the scores on the Constructive attitudes and approaches, Self-monitoring and insight, Health directed activities, Social integration and support, and Emotional distress subscales and the scores on SF-36 Physical functioning, General health perceptions, Vitality, Social functioning, Perceived mental health and Role limitations due to physical and emotional problems subscales.

CONCLUSIONS

The Italian heiQ has strong properties and it can be used routinely also in the Italian healthcare services.

COPD-Specific Self-Management Support Provided by Trained Educators in Everyday Practice is Associated with Improved Quality of Life, Health-Directed Behaviors, and Skill and Technique Acquisition: A Convergent Embedded Mixed-Methods Study

BACKGROUND

There is a necessity to better document the effect of continuing education activities targeted at respiratory educators providing self-management support for patients with chronic obstructive pulmonary disease (COPD). We therefore sought to describe real-life COPD-specific self-management support delivered by respiratory educators who participated in a lecture-based continuing education activity and assess the outcomes of patients with COPD.

METHODS

We conducted a convergent embedded mixed-methods study. Respiratory educators attended a 7-h, lecture-based continuing education activity on self-management support held in Québec, Canada. Four months after the continuing education activity, in their professional practice, trained educators provided self-management support to patients with COPD. One month later, to describe the components of self-management support provided, individual telephone interviews were conducted with educators. Interviews were transcribed verbatim and were qualitatively analyzed. Before self-management support and 6 months afterwards, we assessed the following clinical outcomes of patients with COPD: (1) quality of life (St. George's Respiratory Questionnaire for COPD patients, Impact domain; score 0-100; minimal clinically important difference = - 4; telephone administered); (2a) whether patients had one or more unscheduled doctor visit, (2b) one or more emergency room visit, and (2c) one or more hospitalization in the 6 preceding months (Survey on Living with Chronic Diseases in Canada; telephone administered); and (3a) health-directed behaviors and (3b) skill and technique acquisition (Health Education Impact Questionnaire; score 1-4; self-administered at home). We used mixed models to estimate mean differences and prevalence ratios, with associated 95% confidence intervals.

RESULTS

Trained respiratory educators (nurse: n = 1; respiratory therapist: n = 3; ≥ 15 years of experience of care with patients with chronic disease) invited 75 patients with COPD to participate in the study. Fifty-four individuals with COPD (age, mean ± standard deviation: 68 ± 8 years; men: n = 31) were enrolled and received self-management support. Qualitative analyses revealed that self-management support consisted of one to two visits that included: (1) provision of information on COPD; (2) training in inhalation technique; and (3) smoking cessation advice. No educator reported implementing two or more follow-up visits because of a lack of time and human resources in their work setting. Among patients with COPD, improvements in quality of life were clinically important (adjusted mean difference = - 12.75; 95% confidence interval - 18.79 to - 6.71; p = 0.0001). Health-resource utilization was not different over time (all p values > 0.05). Improvements in health-directed behaviors and skill and technique acquisition were statistically significant (health-directed behaviors: adjusted mean difference = 0.50; 95% confidence interval 0.23-0.77; p = 0.0005; skill and technique acquisition: adjusted mean difference = 0.12; 95% confidence interval 0.01-0.23; p = 0.0293).

CONCLUSIONS

Following a 7-h, lecture-based continuing education activity on COPD-specific self-management support, respiratory educators with significant experience of care provided self-management support that included provision of information, inhalation technique training, and smoking cessation advice. This resulted in enhanced patient quality of life, health-directed behaviors, and skill and technique acquisition. To decrease health resource utilization, the training could employ active learning methods. More time and resources could also be devoted to implementing regular follow-up visits.

The Parker Model: Applying a Qualitative Three-Step Approach to Optimally Utilize Input from Stakeholders When Introducing New Device Technologies in the Management of Chronic Rheumatic Diseases

Background and Objective

Qualitative methods such as semi-structured interviews and focus-groups are used to evaluate the applicability and relevance of device technologies in clinical practice, but when used alone, often lack generalizability. This study aimed to assess the face validity and feasibility of using a composite, three-step qualitative method (the Parker Model), to inform the development and implementation of ava^®, an electromechanical device (e-Device) for subcutaneous self-administration of the biologic, certolizumab pegol (CZP), used to treat rheumatic diseases.

Methods

The Parker Model combines concept mapping (CM), participatory design (PD), and stakeholder evaluation (SE). CM, a structured group process, was used to identify patients’ opinions and concerns regarding the e-Device. Patients used this information in iterative PD sessions to create personal e-Device prototypes in cooperation with a designer and a healthcare professional. SE was performed based on semi-structured group and individual interviews with patients and disease-management stakeholders.

Results

The study recruited 14 patients, two doctors, two nurses, one medical secretary, and four other public servants. Three CM workshops revealed four key considerations: technical usability, physical design, concerns, and enthusiasm. Four personalized prototypes were developed during PD sessions. SE confirmed that the identified considerations were pivotal for the implementation and adaptation of the e-Device.

Conclusions

This study is the first to apply a composite, qualitative research model when introducing an e-Device for the treatment and management of rheumatic disease. Results show that input from patients and other stakeholders using the Parker Model can add value to the development and implementation of an e-Device.

Effects of a COPD self-management support intervention: a randomized controlled trial

BACKGROUND

This study examines the effects of the COPD-specific health promoting self-management intervention "Better living with COPD" on different self-management-related domains, self-efficacy, and sense of coherence (SOC).

METHODS

In a randomized controlled design, 182 people with COPD were allocated to either an intervention group (offered Better living with COPD in addition to usual care) or a control group (usual care). Self-management-related domains were measured by the Health Education Impact Questionnaire (heiQ) before and after intervention. Self-efficacy was measured by the General Self-Efficacy Scale (GSE) and SOC was measured by the 13-item Sense of Coherence Scale (SOC-13). Effects were assessed by ANCOVA, using intention-to-treat (ITT) analysis and per-protocol analysis (PPA).

RESULTS

The PPA and the ITT analysis showed significant positive changes on Constructive attitudes and approaches (heiQ) (ITT: P=0.0069; PPA: P=0.0021) and Skill and technique acquisition (heiQ) (ITT: P=0.0405; PPA: P=0.0356). Self-monitoring and insight (heiQ) showed significant positive change in the PPA (P=0.0494). No significant changes were found on the other self-management domains (heiQ), self-efficacy (GSE), or SOC (SOC-13).

CONCLUSION

Better living with COPD had a significant positive short-term effect on some self-management-related domains, and could be an intervention contributing to the support of self-management in people with COPD. However, further work is needed to establish the clinical relevance of the findings and to evaluate the long-term effects.

Identification, description and appraisal of generic PROMs for primary care: a systematic review

Background

Patients attend primary care with many types of problems and to achieve a range of possible outcomes. There is currently a lack of patient-reported outcome measures (PROMs) designed to capture these diverse outcomes. The objective of this systematic review was to identify, describe and appraise generic PROMs suitable for measuring outcomes from primary care.

Methods

We carried out a systematic Medline search, supplemented by other online and hand-searches. All potentially relevant PROMs were itemised in a long-list. Each PROM in the long-list which met inclusion criteria was included in a short-list. Short-listed PROMs were then described in terms of their measurement properties and construct, based on a previously published description of primary care outcome as three constructs: health status, health empowerment and health perceptions. PROMs were appraised in terms of extent of psychometric testing (extensive, moderate, low) and level of responsiveness (high, medium, low, unknown).

Results

More than 5000 abstracts were identified and screened to identify PROMs potentially suitable for measuring outcomes from primary care. 321 PROMs were long-listed, and twenty PROMs were catalogued in detail. There were five PROMs which measured change directly, without need for a baseline. Although these had less strong psychometric properties, they may be more responsive to change than PROMs which capture status at a point in time. No instruments provided coverage of all three constructs. Of the health status questionnaires, the most extensively tested was the SF-36. Of the health empowerment instruments, the PEI, PAM and heiQ provided the best combination of responsiveness and psychometric testing. The health perceptions instruments were all less responsive to change, and may measure a form of health perception which is difficult to shift in primary care.

Conclusions

This systematic review is the first of its kind to identify papers describing the development and validation of generic PROMs suitable for measuring outcomes from primary care. It identified that: 1) to date, there is no instrument which comprehensively covers the outcomes commonly sought in primary care, and 2) there are different benefits both to PROMs which measure status at a point in time, and PROMs which measure change directly.

Symptom burden and self-management in persons with chronic obstructive pulmonary disease

Purpose

Self-management is crucial for effective COPD management. This study aimed at identifying associations between self-management and sociodemographic characteristics, clinical characteristics, and symptom burden in people with COPD.

Patients and methods

In this cross-sectional study with 225 participants diagnosed with COPD grades II–IV, multiple linear regression analysis was conducted, using sociodemographic and clinical characteristics and symptom burden (COPD Assessment Test) as the independent variables and the eight self-management domains of the Health Education Impact Questionnaire (heiQ) as the outcome variables.

Results

Higher symptom burden was significantly associated with worse scores in all self-management domains (p<0.003), except for self-monitoring and insight (p=0.012). Higher disease severity (p=0.004) and numbers of comorbidities (p<0.001) were associated with more emotional distress, and women scored higher than men on positive and active engagement in life (p=0.001). Higher score in pack-years smoking was associated with lower score in health-directed activities (p=0.006) and self-monitoring and insight (p<0.001), and participation in organized physical training was associated with higher score in health-directed activities (p<0.001). The final models explained 3.7%–31.7% of variance (adjusted R²) across the eight heiQ scales.

Conclusion

A notable finding of this study was that higher symptom burden was associated with worse scores in all self-management domains, except for self-monitoring and insight. In addition, sex, disease severity, comorbidity, pack-years smoking, and participation in organized physical training were associated with one or two self-management domains. The study contributes to improved understanding of self-management in COPD. However, the explained variance levels indicate that more research needs to be done to uncover what else explains self-management domains in COPD.

Mechanical diagnosis and therapy enhances attitude toward self-management in people with musculoskeletal disorders: A preliminary evidence with a before-after design

Objectives:

Mechanical diagnosis and therapy is one of the most common approaches for the management of low back pain. In mechanical diagnosis and therapy, a great emphasis is placed on patient education so that patients can manage their problems by themselves. However, there has been no evidence that mechanical diagnosis and therapy actually enhances patient’s self-management skills. This study aimed to preliminarily investigate whether self-reported skills of self-management for musculoskeletal problems are enhanced through the course of mechanical diagnosis and therapy.

Method:

Outpatients with musculoskeletal disorders in a local orthopedic clinic were included. The primary outcome measures were the “Self-monitoring and Insight” and “Skill and Technique Acquisition” scores of the Health Education Impact Questionnaire, where higher scores indicate greater self-management skills. Mechanical diagnosis and therapy was undertaken up to a maximum of twice per week for 1 month. The Self-monitoring and Insight and Skill and Technique Acquisition scores before and 1 month after the mechanical diagnosis and therapy interventions were compared. Proportions of patients who exceed the threshold for “reliable change” in the Health Education Impact Questionnaire scores (% >positive “reliable change”) and proportions of patients with the net positive “reliable change” (% net positive “reliable change”) were investigated.

Results:

Forty-five patients participated and 97.8% completed the 1-month follow-up. The Self-monitoring and Insight and Skill and Technique Acquisition scores significantly increased at the follow-up (Self-monitoring and Insight, p = 0.002; Skill and Technique Acquisition, p < 0.001. The % >positive “reliable change” (Self-monitoring and Insight = 22.2%, Skill and Technique Acquisition = 48.9%) and % net positive “reliable change” (Self-monitoring and Insight = 13.3%, Skill and Technique Acquisition = 46.7%) in this study were comparative to or greater than self-management programs in previous studies (%> positive “reliable change’: Self-monitoring and Insight = 20.5%, Skill and Technique Acquisition = 30.7%; % net positive “reliable change”: Self-monitoring and Insight = 14.1%, Skill and Technique Acquisition = 23.0%).

Conclusion:

This study provides a preliminary evidence that mechanical diagnosis and therapy enhances patient’s self-management skills, particularly in the self-monitoring skills for symptoms/functions and the self-management skill for symptoms/problems.

The Health Literacy Questionnaire (HLQ) at the patient-clinician interface: a qualitative study of what patients and clinicians mean by their HLQ scores

BACKGROUND

The Health Literacy Questionnaire (HLQ) has nine scales that each measure an aspect of the multidimensional construct of health literacy. All scales have good psychometric properties. However, it is the interpretations of data within contexts that must be proven valid, not just the psychometric properties of a measurement instrument. The purpose of this study was to establish the extent of concordance and discordance between individual patient and clinician interpretations of HLQ data in the context of complex case management.

METHODS

Sixteen patients with complex needs completed the HLQ and were interviewed to discuss the reasons for their answers. Also, the clinicians of each of these patients completed the HLQ about their patient, and were interviewed to discuss the reasons for their answers. Thematic analysis of HLQ scores and interview data determined the extent of concordance between patient and clinician HLQ responses, and the reasons for discordance.

RESULTS

Highest concordance (80%) between patient and clinician item-response pairs was seen in Scale 1 and highest discordance (56%) was seen in Scale 6. Four themes were identified to explain discordance: 1) Technical or literal meaning of specific words; 2) Patients' changing or evolving circumstances; 3) Different expectations and criteria for assigning HLQ scores; and 4) Different perspectives about a patient's reliance on healthcare providers.

CONCLUSION

This study shows that the HLQ can act as an adjunct to clinical practice to help clinicians understand a patient's health literacy challenges and strengths early in a clinical encounter. Importantly, clinicians can use the HLQ to detect differences between their own perspectives about a patient's health literacy and the patient's perspective, and to initiate discussion to explore this. Provision of training to better detect these differences may assist clinicians to provide improved care. The outcomes of this study contribute to the growing body of international validation evidence about the use of the HLQ in different contexts. More specifically, this study has shown that the HLQ has measurement veracity at the patient and clinician level and may support clinicians to understand patients' health literacy and enable a deeper engagement with healthcare services.

Percentile ranks and benchmark estimates of change for the Health Education Impact Questionnaire: Normative data from an Australian sample

Objective:

Participant self-report data play an essential role in the evaluation of health education activities, programmes and policies. When questionnaire items do not have a clear mapping to a performance-based continuum, percentile norms are useful for communicating individual test results to users. Similarly, when assessing programme impact, the comparison of effect sizes for group differences or baseline to follow-up change with effect sizes observed in relevant normative data provides more directly useful information compared with statistical tests of mean differences and the evaluation of effect sizes for substantive significance using universal rule-of-thumb such as those for Cohen’s ‘d’. This article aims to assist managers, programme staff and clinicians of healthcare organisations who use the Health Education Impact Questionnaire interpret their results using percentile norms for individual baseline and follow-up scores together with group effect sizes for change across the duration of typical chronic disease self-management and support programme.

Methods:

Percentile norms for individual Health Education Impact Questionnaire scale scores and effect sizes for group change were calculated using freely available software for each of the eight Health Education Impact Questionnaire scales. Data used were archived responses of 2157 participants of chronic disease self-management programmes conducted by a wide range of organisations in Australia between July 2007 and March 2013.

Results:

Tables of percentile norms and three possible effect size benchmarks for baseline to follow-up change are provided together with two worked examples to assist interpretation.

Conclusion:

While the norms and benchmarks presented will be particularly relevant for Australian organisations and others using the English-language version of the Health Education Impact Questionnaire, they will also be useful for translated versions as a guide to the sensitivity of the scales and the extent of the changes that might be anticipated from attendance at a typical chronic disease self-management or health education programme.

Patient empowerment: a systematic review of questionnaires measuring empowerment in cancer patients

BACKGROUND

There is an increased attention to and demand for patient empowerment in cancer treatment and follow-up programs. Patient empowerment has been defined as feeling in control of or having mastery in relation to cancer and cancer care. This calls for properly developed questionnaires assessing empowerment from the user perspective. The aim of this review was to identify questionnaires and subscales measuring empowerment and manifestations of empowerment among cancer patients.

MATERIALS AND METHODS

We conducted a systematic search of the PubMed, PsycINFO and CINAHL databases. Empowerment and multiple search terms associated with empowerment were included. We included peer-reviewed articles published in English, which described questionnaires measuring empowerment or manifestations of empowerment in a cancer setting. In addition, the questionnaire had to be a patient-reported outcome measure for adult cancer patients.

RESULTS

Database searches identified 831 records. Title and abstract screening resulted in 482 records being excluded. The remaining 349 full text articles were retrieved and assessed for eligibility. This led to the inclusion of 33 individual instruments measuring empowerment and manifestations of empowerment. Of these, only four were specifically developed to measure empowerment, and two were originally developed for the cancer setting, whereas the remaining two were developed elsewhere, but adapted to the cancer setting. The other 29 questionnaires were not intended to measure the concept of empowerment, but focused on patient-centered care, patient competence, self-efficacy, etc. However, they were included because part of the instrument (at least five items) was considered to measure empowerment or manifestations of empowerment.

CONCLUSION

Our study provides an overview of the available questionnaires, which can be used by researchers and practitioners who wish to measure the concept of empowerment among cancer patients. Very few questionnaires were explicitly developed to explore empowerment, and the review brings to light a significant lack of questionnaires that measure patient empowerment comprehensively.

Validation of the dutch version of the health education impact questionnaire (HEIQ) and comparison of the Dutch translation with the English, German and French HEIQ

Background

The Health Education Impact Questionnaire (heiQ) evaluates the effectiveness of health education and self-management programs provided to people dealing with a wide range of conditions. Aim of this study was to translate, culturally adapt and validate the Dutch translation of the heiQ and to compare the results with the English, German and French translations.

Methods

A systematic translation process was undertaken. Psychometric properties were studied among patients with arthritis, atopic dermatitis, food allergy and asthma (n = 286). Factorial validity using confirmatory factor analysis, item difficulty (D), item remainder correlation and composite reliability were conducted. Stability was tested using the intra-class correlation coefficient (ICC).

Results

Items were well understood and only minor language adjustments were required. Confirmatory fit indices were >0.95 and item difficulty was D ≥ 0.65 for all items in scales showing acceptable fit indices, except for the reversed Emotional distress scale. Composite reliability ranged between 0.67 and 0.85. Test-retest reliability (n = 93) ICC varied between 0.61 and 0.84. Comparisons with other translations showed comparable fit indices. A lower ICC on Self-monitoring and insight scale was observed.

Conclusions

The Dutch translation of the heiQ was found to be well understood and user friendly by patients with Rheumatoid Arthritis, Atopic Dermatitis, Food allergy and asthma and to have robust psychometric properties for evaluating the impact of health education and self-management programs. Given the wide applications of the heiQ and the comparability of the Dutch results with the English, German and French version, the heiQ is a practical and useful questionnaire to evaluate the impact of self-management support programs in different countries and populations with different diseases.

Making robust decisions about the impact of health education programs: Psychometric evaluation of the Health Education Impact Questionnaire (heiQ) in diverse patient groups in Norway

OBJECTIVE

To undertake a rigorous psychometric evaluation of the widely used eight-scale heiQ version 2.0 (evaluating immediate effects of self-management interventions) in diverse patient groups in Norway.

METHODS

Cross-sectional survey data were collected from 1019 Norwegians. Data were extracted from studies among people with musculoskeletal disorders (n=516), psoriasis (n=254), heart disease (n=97), and Type 2 diabetes (n=152). To investigate the factorial validity of the Norwegian heiQ, confirmatory factor analyses (CFA) were carried out using Mplus.

RESULTS

One-factor model fit, without modifications, was acceptable for the Emotional distress scale. Only one correlated residual was required to be fitted in each of the other scales to achieve satisfactory model fit. The postulated highly restricted full eight-factor model (no cross-loadings, no correlated residuals) showed good fit to the data. Internal consistency was acceptable for most scales (0.72-0.90) but low for Self-monitoring and insight.

CONCLUSION

This study of the Norwegian heiQ replicates the factor structure of the original Australian heiQ, using robust and highly restricted CFA procedures, demonstrating a clean independent clusters model structure.

PRACTICE IMPLICATIONS

Researchers, program implementers and policymakers could use the Norwegian heiQ with confidence to generate reliable information on program outcomes and support quality improvement activities.

Measuring health literacy in community agencies: a Bayesian study of the factor structure and measurement invariance of the health literacy questionnaire (HLQ)

BACKGROUND

The development of the Health Literacy Questionnaire (HLQ), reported in 2013, attracted widespread international interest. While the original study samples were drawn from clinical and home-based aged-care settings, the HLQ was designed for the full range of healthcare contexts including community-based health promotion and support services. We report a follow-up study of the psychometric properties of the HLQ with respondents from a diverse range of community-based organisations with the principal goal of contributing to the development of a soundly validated evidence base for its use in community health settings.

METHODS

Data were provided by 813 clients of 8 community agencies in Victoria, Australia who were administered the HLQ during the needs assessment stage of the Ophelia project, a health literacy-based intervention. Most analyses were conducted using Bayesian structural equation modelling that enables rigorous analysis of data but with some relaxation of the restrictive requirements for zero cross-loadings and residual correlations of 'classical' confirmatory factor analysis. Scale homogeneity was investigated with one-factor models that allowed for the presence of small item residual correlations while discriminant validity was studied using the inter-factor correlations and factor loadings from a full 9-factor model with similar allowance for small residual correlations and cross-loadings. Measurement invariance was investigated scale-by-scale using a model that required strict invariance of item factor loadings, thresholds, residual variances and co-variances.

RESULTS

All HLQ scales were found to be homogenous with composite reliability ranging from 0.80 to 0.89. The factor structure of the HLQ was replicated and 6 of the 9 scales were found to exhibit clear-cut discriminant validity. With a small number of exceptions involving non-invariance of factor loadings, strict measurement invariance was established across the participating organisations and the gender, language background, age and educational level of respondents.

CONCLUSIONS

The HLQ is highly reliable, even with only 4 to 6 items per scale. It provides unbiased mean estimates of group differences across key demographic indicators. While measuring relatively narrow constructs, the 9 dimensions are clearly separate and therefore provide fine-grained data on the multidimensional area of health literacy. These analyses provide researchers, program managers and policymakers with a range of robust evidence by which they can make judgements about the appropriate use of the HLQ for their community-based setting.
