Self-management education: history, definition, outcomes, and mechanisms

Illness perceptions and COPD: an emerging field for COPD patient management

OBJECTIVE

Patients with chronic obstructive pulmonary disease have perceptions of their illness and its management that determine their coping behaviors (e.g., adherence, self-management) and, consequently, their outcomes. This article reviews the empirical literature on illness perceptions in patients with COPD to provide clinicians with information regarding the potential utility of incorporating illness perceptions into clinical COPD care.

METHOD

A literature search in PubMed identified 16 studies examining associations between illness perceptions and outcomes in patients with COPD.

RESULTS

Seven of the 16 papers were from US authors, followed by 3 each from the UK and The Netherlands, and one study each from Australia, Canada, and New Zealand. The first study was published in 1983, and the numbers of patients per study ranged fom 10 to 266. The illness perceptions were those delineated by two theoretical models (cognitive behavioral theory and the Common Sense Model), and they were assessed with open interviews and validated questionnaires. Outcomes were disability, quality of life, and psychological characteristics. The studies revealed clinically meaningful associations between illness perceptions and outcomes.

CONCLUSION

Our review supports the incorporation of illness perceptions into clinical care for patients with COPD. The assessment of illness perceptions should be routine, similar to routine assessments of pulmonary function. Discussing and changing illness perceptions will improve COPD patients' quality of life and reduce their levels of disability. COPD-specific assessments ("diagnosis") of illness perceptions and COPD-specific intervention methods ("therapy") that help change inadequate and maladaptive illness perceptions are research priorities.

Educational needs in adults with congenitally malformed hearts

BACKGROUND AND AIM

The number of adults with congenitally malformed hearts is growing, and there is an increasing demand for their continuous follow-up. At present, different programmes have been established for adults with congenital cardiac disease, but there is a lack of knowledge regarding how education and psychosocial support should be given to achieve effects. Before developing educational programmes, it is necessary to be aware of the perspective of the patients. The aim of our study, therefore, was to describe how adults with congenitally malformed hearts experience their educational needs.

METHODS

The study had a qualitative design. We interviewed 16 adults, aged from 19 to 55 years, with congenitally malformed hearts.

RESULTS

Two-way communication emerged as crucial to individualising education. Without good communication, those with congenitally malformed hearts, receiving information from providers of healthcare, are unable to transfer the information received. Thus, individualised education gives access to knowledge and the tools required to manage important areas in life, such as the congenital cardiac malformation, physical activity, the situation of life, treatment, and resources available for healthcare. The information given should provide easy access to knowledge through proper educational materials and methods, and be given with respect for the individual. This is facilitated if the education is tailored to the requirements of the individual in a holistic approach, and is provided through good communication.

CONCLUSION

Our investigation shows that a structured educational programme needs to start from the perspective of the individual patient, and that two-way communication needs to be taken into consideration to enhance knowledge.

Effects of a Telephone-Based Exercise Intervention for Dementia Caregiving Wives: A Randomized Controlled Trial

Despite the importance of self-care for dementia caregivers, few interventions have included a focus on health behaviors. The current study reports outcomes of a telephone-based exercise intervention designed for women caring for a spouse with dementia. Caregivers (N = 137) were randomized to intervention or control conditions. Participants with at or below-median exercise scores at baseline had a significantly greater increase in exercise at six-month follow-up compared to their control counterparts. At 6 months, participants had greater reductions in perceived stress relative to controls. Participants also reported significantly greater increases in exercise self-efficacy than caregivers in the control group at both follow-up points. . Results indicate that spouse caregivers are able to increase their physical activity and that a focus on exercise in multi-component interventions may be beneficial. Debate and discussion is needed to inform expectations for program impacts and their maintenance and to explore the interface between enhanced self-care and caregiving perceptions.

[Patient education in rheumatologic care--a review]

Patient education is a medical intervention for patients with chronic diseases to increase knowledge of their disease, self-efficacy, self-management and consumer behaviour. The goal is to improve their disease outcome, social participation and quality of life. This article reviews concepts, modalities and knowledge on effectiveness of patient education. The results of different studies in different rheumatic diseases on efficacy will be summarized including a small number of cost-benefit analyses. Most studies report on significant and relevant improvements of knowledge, self-efficacy and health status. With respect to disease specific outcomes low to moderate effect sizes with a short duration have been observed. Especially good results have been reported when physical training or other methods of rehabilitation were included. There are marked improvements in consumer behaviour of health measures and sickness leave. A better understanding of information needs and baseline characteristics of patients is necessary to develop more appropriate educational interventions focussed on relevant outcomes that can be improved by educational measures.

Five factor model personality factors moderated the effects of an intervention to enhance chronic disease management self-efficacy

OBJECTIVES

Peer led interventions can enhance patient self-efficacy for managing chronic illnesses, but little is known regarding the moderators or duration of their effects. We hypothesized Homing in on Health (HIOH), a variant of the Chronic Disease Self-Management Program, would be most effective in patients high in neuroticism and low in extraversion, openness, agreeableness, and/or conscientiousness.

DESIGN

Analysis of data from subjects (N=415) enrolled in an ongoing randomized controlled trial.

METHODS

Regression analyses were conducted to explore whether Five Factor Model (FFM) personality factors moderated the effects of HIOH, delivered in subjects' homes or via telephone, on disease management self-efficacy. Data were collected at 6 time points over the course of 1 year.

RESULTS

Compared with control and telephone HIOH, home HIOH significantly increased self-efficacy, an effect peaking at 6 weeks and fully attenuating by 1 year. Moderation analyses revealed the benefit was confined to patients higher in neuroticism and/or lower in conscientiousness, agreeableness, and extraversion.

CONCLUSIONS

A peer led intervention to enhance disease management self-efficacy had only short-term effects, and FFM personality factors moderated those effects. Measuring personality factors in chronically ill individuals may facilitate targeting of self-management interventions to those most likely to respond.

Perceived control moderated the self-efficacy-enhancing effects of a chronic illness self-management intervention

OBJECTIVE

Identifying moderators of the effects of self-efficacy-enhancing interventions could improve their efficiency. We examined the effects of a home-based variant of the Chronic Disease Self-Management Program on self-efficacy, and explored the moderating effects of perceived control over self-management (PCSM).

METHODS

In a randomized controlled trial, patients (N= 415) aged>40 years with various chronic conditions plus basic activity impairment and/or significant depressive symptoms were randomized to one of three groups: intervention provided in homes or by telephone, v. usual care control. We used mixed effects linear models for repeated measures to examine effects on self-management self-efficacy at 6-month follow-up and explore moderation by PCSM.

RESULTS

Only the home intervention had a significant self-efficacy-enhancing effect (Wald test, chi( 2) = 13.8, p = 0.008; effect size = 0.3). The effect was moderated by PCSM, considered as a continuous [effective in subjects with lower PCSM (Wald test, chi(2) = 13.4, p = 0.009)] or categorical (effective only for subjects in the lowest tercile) variable.

CONCLUSIONS

People with lower PCSM appear more likely to experience enhanced self-efficacy from chronic illness self-management training than those with higher PCSM. These findings, although preliminary, suggest that office-based measurement of PCSM might identify those chronically ill patients likely to benefit most from self-management training.

Optimizing Stroke Systems of Care by Enhancing Transitions Across Care Environments

Stroke affects many aspects of the lives of stroke survivors and their family caregivers. Supporting long-term recovery and rehabilitation are necessary to help stroke survivors adapt to living with the effects of stroke and to help family members adapt to the caregiving role. During recovery and rehabilitation, many elements of the health care continuum are utilized, including emergency response, acute care, inpatient and outpatient rehabilitation, and community and long-term care. With the advent of thrombolytic therapy and the benefits of stroke units, stroke survival and outcomes are improving. As a result, the current emphasis of stroke system improvement is to implement stroke units throughout the developed world. To enhance the patient centeredness of stroke care delivery, an important next phase of stroke system improvement will center on the experiences of stroke survivors and their family caregivers as they move through diverse care environments. The objective of this article was to conduct a scoping review of the literature on stroke transitions to identify the current areas of research emphasis. This article highlights stroke survivors’ and family caregivers’ experiences with transitions across care environment and some potential strategies to improve those transitions.

Health Promotion for People With Disabilities: Implications for Empowering the Person and Promoting Disability-Friendly Environments

Developing innovative strategies that promote health among people with disabilities has emerged as an important public health priority. People with disabilities report fewer healthy days than the general population and lower rates of health-promoting behaviors (eg, physical inactivity and poor nutritional intake). One of the major priorities in health promotion for people with disabilities is to prevent secondary conditions. Secondary conditions are health concerns that are not a direct result of the primary disability but rather are acquired at a later time due to lifestyle changes associated with the disability (eg, weight gain, pressure sores, pain, fatigue, depression). It is important for health professionals to recognize that the substantial health disparities that exist between people with and without disabilities requires greater attention to establishing disability-friendly environments that reduce architectural, programmatic, and attitudinal barriers that make it difficult for them to engage in self-initiated health promotion practices. Empowering people with disabilities to self-manage their health requires the full support of community service providers in promoting greater access to all health promotion venues, programs, and services.

Integrating diabetes self-management with the health goals of older adults: a qualitative exploration

OBJECTIVE

This study investigates the life and health goals of older adults with diabetes, and explores the factors that influence their diabetes self-management.

METHODS

Qualitative in-depth interviews were conducted with 24 older adults with diabetes and other morbid conditions and/or their caregivers, when appropriate.

RESULTS

Participants' provided a consistent set of responses when describing life and health goals. Participants described goals for longevity, better physical functioning, spending time with family, or maintaining independence. Diabetes discordant conditions, but not diabetes, were seen as barriers to life goals for participants with functional impairments. Functionally independent participants described additional health goals that related to diabetes self-management as diabetes was seen often a barrier to life goals. Caregivers, co-morbid conditions, denial and retirement were among the factors that influenced initiation of diabetes self-management.

CONCLUSION

Participants endorsed health goals and diabetes self-management practices that they believed would help them accomplish their life goals. Functional capabilities and social support were key factors in the relationship between diabetes self-management and their broader goals.

PRACTICE IMPLICATIONS

When planning diabetes treatments, clinicians, patients and caregivers should discuss the relationship between diabetes self-management and health and life goals as well as the affects of functional limitations and caregiver support.

Literacy, social stigma, and HIV medication adherence

BACKGROUND

Prior studies have linked limited literacy to poorer HIV medication adherence, although the precise causal pathways of this relationship have only been initially investigated.

OBJECTIVE

To examine whether social stigma is a possible mediator to the relationship between literacy and self-reported HIV medication adherence.

DESIGN

Structured patient interviews with a literacy assessment, supplemented by medical chart review, were conducted among patients receiving care at infectious disease clinics in Shreveport, Louisiana and Chicago, Illinois. Literacy was measured using the Rapid Estimate of Adult Literacy in Medicine (REALM), while stigma was measured using items taken from the Patient Medication Adherence Questionnaire (PMAQ).

PARTICIPANTS

Two hundred and four consecutive patients participated.

RESULTS

Approximately one-third of the patients (30.4%) were less than 100% adherent to their regimen, and 31.4% had marginal (7th-8th grade) or low (< or = 6th grade) literacy. In multivariate analyses, patients with low literacy were 3.3 times more likely to be non-adherent to antiretroviral regimens (95% CI 1.3-8.7; p < 0.001). Perceived social stigma was found to mediate the relationship between literacy and medication adherence (AOR 3.1, 95% CI 1.3-7.7).

CONCLUSIONS

While low literacy was a significant risk factor for improper adherence to HIV medication regimens in our study, perceived social stigma mediated this relationship. Low literacy HIV intervention strategies may also need to incorporate more comprehensive psychosocial approaches to overcome stigma barriers.

Guided care: a new frontier for adults with chronic conditions

PURPOSE

This article describes "Guided Care," a promising new model of case management that includes disease management, self-management, transitional care, and caregiver support for multimorbid patients and their families.

PRIMARY PRACTICE SETTINGS

Guided Care nurses, based at primary care practices, extend services to the home and all the other settings where their patients receive care.

FINDINGS AND CONCLUSIONS

Guided Care nurses take responsibility for 50-60 multimorbid patients. For each patient, the nurse performs a home assessment and creates an evidence-based plan of care. In partnership with the primary physician, the Guided Care nurse then monitors and coaches the patient monthly, coordinates the patient's transitions between providers and sites of care, educates and supports family caregivers, and facilitates access to community resources.

IMPLICATIONS FOR CASE MANAGEMENT PRACTICE

As a next stage in the evolution of case management, Guided Care may be supported by Medicare and, therefore, adopted widely throughout the American healthcare.

The Stroke Self-Efficacy Questionnaire: measuring individual confidence in functional performance after stroke

AIMS AND OBJECTIVES

The aim was to develop a questionnaire for use by practitioners working in stroke care to measure self-efficacy judgements in specific domains of functioning relevant to individuals following stroke.

BACKGROUND

The prevalence of stroke is set to rise across the developed world especially amongst the elderly population. Recovery and adjustment in the longer term can be affected by many different factors. Current objective measures of functional performance used in many stroke programmes may not fully explain the extent of personal levels of confidence that could ultimately influence outcome.

METHODS

Three separate studies were conducted to develop the Stroke Self-Efficacy Questionnaire. A total of 112 stroke survivors, between 2 and 24 weeks, poststroke participated in the study. Development of the scale was undertaken between 2004 and 2006.

RESULTS

The final 13-item Stroke Self-Efficacy Questionnaire was found to have good face validity and feasibility to use in the recovery period following stroke. Cronbach Alpha was 0.90 suggesting good internal consistency, and criterion validity was high compared with the Falls Efficacy Scale, r = 0.803, p < 0.001. The Stroke Self-Efficacy Questionnaire was also able to discriminate between those participants walking and not walking.

CONCLUSIONS

Preliminary psychometric testing of the new Stroke Self-Efficacy Questionnaire has indicated that it is a valid measure of confidence for functional performance and aspects of self-management relevant for individuals recovering from stroke.

RELEVANCE TO CLINICAL PRACTICE

The Stroke Self-Efficacy Questionnaire could assist clinicians and researchers working in acute stroke care and rehabilitation to screen levels of confidence of stroke survivors in relation to functional performance and self-management. The Stroke Self-Efficacy Questionnaire could be used as part of battery of stroke outcome measures to provide a more comprehensive overview of factors influencing performance in the individuals recovering from a stroke.

Symptom clusters in incident dialysis patients: associations with clinical variables and quality of life

BACKGROUND

To date, the pathophysiology underlying symptoms in renal patients is still unclear. Symptom management research suggests that identification of related clusters of symptoms could provide insight into underlying determinants associated with multiple symptom experience. Theoretically, symptoms within a cluster could have a synergistic relationship. We aimed to identify symptom clusters in incident dialysis patients, and investigated associations between symptom clusters, clinical variables, functional status as measured by the Karnofsky Index and quality of life.

METHODS

1553 haemodialysis (HD) and peritoneal dialysis (PD) patients completed the Kidney Disease Quality of Life Short Form symptom/problem list at 3 months after the start of dialysis. Principal component analysis using varimax rotation was used to identify symptom clusters.

RESULTS

Patients were bothered by an average of 2.8 (+/-2.4) symptoms of 'moderate bother' or more. Three clusters were identified, explaining 49% of the total variance. All clusters showed strong negative associations with the SF-36 quality of life dimensions (-0.142 to -0.593) and with functional status (-0.130 to -0.332) in HD and PD patients. In contrast, only the clinical variables serum albumin (-0.084 to -0.232) and haemoglobin (-0.068 to -0.126) were associated with all clusters in HD patients, and Kt/V(urea) (-0.089 to -0.125) in PD patients.

CONCLUSIONS

Symptom clustering does not explain the lack of meaningful associations between symptoms and clinical variables. Strong associations of symptom clusters with quality of life dimensions suggest that psychological factors could better explain symptom burden. Patients' perceptions of symptoms should be routinely assessed as part of clinical care to improve self-management strategies.

Designing patient-related interventions in COPD care: empirical test of a theoretical model

OBJECTIVES

The aim of this exploratory study was to test the applicability of a theoretical model to develop patient-related interventions. In this model knowledge, psychosocial mediators, self-efficacy and behaviour are determinants of patient-related interventions.

METHODS

The model was tested on 278 patients with mild or moderate chronic obstructive pulmonary disease (COPD), recruited in a primary care setting. Hierarchical regression analyses were applied using data from self-reported questionnaires and clinical data from an electronic data registry.

RESULTS

Knowledge, psychosocial mediators, self-efficacy and behaviour proved to be, to a moderate degree, predictors of outcomes in COPD care. Moreover, physical activity appeared to be a significant predictor for all clinical and functional outcomes.

CONCLUSION

Theoretically expected associations of patient-related interventions are existent in patients with mild or moderate COPD. The application of theoretical models in designing patient-directed interventions in COPD care is therefore feasible.

PRACTICE IMPLICATIONS

More attention should be paid to the patterns of physical activity in patients with mild to moderate COPD. The results of this study are also useful in the development of patient-related interventions. Future interventions should be designed along the lines of theory on behaviour change, such as social cognitive theory.

Access and Coordination of Health Care Service for People With Disabilities

Individuals with disabilities often have multiple complex medical and nonmedical needs. Furthermore, in the current facility-directed health care system, they are at enhanced risk of receiving poorly coordinated, suboptimal care. This is especially problematic because individuals with disabilities face multiple barriers to receiving quality health care services, ranging from structural barriers (e.g., physical access to doctors' offices) to procedural barriers (e.g., difficulty scheduling appointments, problems obtaining insurance coverage). By contrast, a consumer-directed approach to health care (distinct from facility-directed health care) can be effectual, cost-effective, and subjectively satisfying. This brief commentary addresses the importance of a consumer-directed approach to the delivery of health care to individuals with disabilities and the need for specific assessments of the experiences of people with disabilities regarding their care. As such, it proposes recommendations for future policy interventions.

Patient education programs--can they improve outcomes in COPD?

It is important to assess the effectiveness of patient education programs for people with COPD (chronic obstructive pulmonary disease) to ensure that limited health resources are being spent effectively. We aimed to assess the effectiveness of programs reported to date, and to look for ways of designing more effective programs.

COPD patient education to date has produced little demonstrated success, but studies, education programs and study reports all show limitations. To demonstrate links between outcomes and patient education program components, there is a need for more trials which combine process and outcome evaluation. Programs to date have relied too heavily on the provision of medical information to patients. Programs which also aim to improve disease management self-efficacy hold promise but further determinants of health behavior should be included also, as part of more systematic program design. Program components need to be clearly described and the rationale for their use justified in trial reports. This will produce an evidence base that should show what role education programs can play in improving outcomes, and inform the development of more effective programs.

Depressive symptoms moderated the effect of chronic illness self-management training on self-efficacy

BACKGROUND

Identifying moderators of the effects of self-efficacy enhancing interventions could facilitate their refinement and more targeted, cost-effective delivery. Current theories and data concerning the potential moderating effect of depressive symptoms on interventions to enhance patient chronic illness self-management self-efficacy are conflicting.

OBJECTIVES

To explore the moderating effect of depressive symptoms on the effect of an intervention to enhance patient self-efficacy for self-managing chronic illness.

RESEARCH DESIGN

Regression analyses using baseline and postintervention (6 weeks) data from an ongoing randomized controlled trial.

SUBJECTS

Patients (N = 415) aged >or=40 years recruited from a primary care network in Northern California with arthritis, asthma, chronic obstructive pulmonary disease, congestive heart failure, depression, and/or diabetes mellitus, plus impairment in >or=1 basic activity, and/or a score of >or=4 on the 10-item Center for Epidemiologic Studies Depression Scale (CES-D).

MEASURES

Stanford self-efficacy scale, self-reported depression, CES-D, and Medical Outcomes Study Short Form health status questionnaire (SF-36) Mental Component Summary score.

RESULTS

Regression analyses revealed the intervention was effective primarily in those with self-reported depression (interaction effect F = 8.24, P = 0.0003), highest CES-D score category (F = 5.68, P = 0.0037), and lowest (most depressed) Mental Component Summary-36 tercile (F = 4.36, P = 0.0135).

CONCLUSIONS

Individuals with more depressive symptoms seem more likely to experience self-efficacy gains from chronic illness self-management training than individuals with less depressive symptoms. Future self-management training studies should stratify subjects within study groups by depressive symptom level to further explore its potential moderating effect.

A situation-specific theory of heart failure self-care

Heart failure, a common syndrome in developed countries worldwide, is associated with poor quality of life, frequent rehospitalizations, and early death. Self-care is essential to improving outcomes in this patient population. The purpose of this article is to describe a situation-specific theory of heart failure self-care in which self-care is defined as a naturalistic decision-making process involving the choice of behaviors that maintain physiologic stability (maintenance) and the response to symptoms when they occur (management). Self-care maintenance is further defined to encompass routine symptom monitoring and treatment adherence. Self-care management is characterized as a process initiated by symptom recognition and evaluation, which stimulates the use of self-care treatments and treatment evaluation. Confidence in self-care is thought to moderate and/or mediate the effect of self-care on various outcomes. Four propositions were derived from the self-care of heart failure conceptual model: (1) symptom recognition is the key to successful self-care management; (2) self-care is better in patients with more knowledge, skill, experience, and compatible values; (3) confidence moderates the relationship between self-care and outcomes; and (4) confidence mediates the relationship between self-care and outcomes. These propositions were tested and supported using data obtained in previous research. Support of these propositions provides early evidence for this situation-specific theory of heart failure self-care.

Randomized controlled trial of an internet-based versus face-to-face dyspnea self-management program for patients with chronic obstructive pulmonary disease: pilot study

Background

People with chronic obstructive pulmonary disease (COPD) continue to experience dyspnea with activities of daily living (ADL) despite optimal medical management. Information and communication technologies may facilitate collaborative symptom management and could potentially increase the reach of such interventions to those who are unable to attend face-to-face pulmonary rehabilitation or self-management programs.

Objective

The purpose of this randomized study was to test the efficacy of two 6-month dyspnea self-management programs, Internet-based (eDSMP) and face-to-face (fDSMP), on dyspnea with ADL in people living with COPD.

Methods

We randomly assigned 50 participants with moderate to severe COPD who were current Internet users to either the eDSMP (n = 26) or fDSMP (n = 24) group. The content of the two programs was similar, focusing on education, skills training, and ongoing support for dyspnea self-management, including independent exercise. The only difference was the mode (Internet/personal digital assistant [PDA] or face-to-face) in which the education sessions, reinforcement contacts, and peer interactions took place. Participants returned to one of two academic clinical sites for evaluation at 3 and 6 months. The primary outcome of dyspnea with ADL was measured with the Chronic Respiratory Questionnaire. Secondary outcomes of exercise behavior, exercise performance, COPD exacerbations, and mediators, such as self-efficacy and social support, were also measured. A satisfaction survey was administered and a semistructured exit interview was conducted at the final visit.

Results

The study was stopped early due to multiple technical challenges with the eDSMP, but follow-up was completed on all enrolled participants. Data were available for 39 participants who completed the study (female: 44%; age: 69.5 ± 8.5 years; percent predicted forced expiratory volume in 1 s: 49.6 ± 17.0%). The fDSMP and eDSMP showed similar clinically meaningful changes in dyspnea with ADL from baseline to 3 months (fDSMP: + 3.3 points; eDSMP: + 3.5 points) and sustained these improvements at 6 months (fDSMP: + 4.0 points; eDSMP: + 2.5 points; time effects P < .001; group by time P = .51). Self-reported endurance exercise time (P = .001), physical functioning (P = .04), and self-efficacy for managing dyspnea (P = .02) also showed positive improvements over time in both groups with no significant differences with respect to program modality. Participants who completed the study reported favorable satisfaction with the programs.

Conclusions

Although there were numerous technical challenges with the eDSMP, both dyspnea self-management programs were effective in reducing dyspnea with ADL in the short term. Our findings will need to be confirmed in a larger randomized trial with more mature Web and personal digital assistant tools, use of a control group, and longer follow-up.

Improving patient-clinician communication about chronic conditions: description of an internet-based nurse E-coach intervention

BACKGROUND

Studies show that patients who have higher self-efficacy and participate actively in their care have better disease management. Patient-provider Internet portals offer an exciting new venue for empowering and engaging patients in better management of chronic conditions.

OBJECTIVES

To describe development of an Internet-based health coaching intervention.

APPROACH

An Internet-based health coaching intervention to enhance patient-provider communication regarding three common conditions, chronic pain, depression, and impaired mobility, was developed. Using principles of self-management, the intervention aimed to engage and empower patients to collaborate with their primary care physician in managing their health conditions. Delivered online by nurse electronic coaches (e-coaches), the intervention involved a standardized set of e-mails and worksheets targeting self-efficacy, patient education, and motivation to improve health.

RESULTS

Participants in the intervention (N = 121) primarily used the automated elements of the program, although 35% exchanged e-mails with the nurse e-coach. Most patients (88%) who contacted the e-coach were interested in further coaching. Patients who viewed the online worksheets did so repeatedly; 42 patients opened the worksheets 107 times prior to the visit.

DISCUSSION

The Internet-based coaching intervention departs substantially from usual nursing care but warrants further study given its potential to offer considerable benefits to large numbers of patients. Several challenges were identified to providing patient coaching and self-management support via the Internet, but this efficient and low-cost approach offers an innovative opportunity to improve patient-clinician partnerships in managing chronic conditions. As patients become more accustomed to electronic communication, nurses can play an important role, joining efforts to develop this new realm to promote patients as partners in managing their health conditions.

What is the Optimal Duration of Participation in a Community-Based Health Promotion Program for Older Adults?

Optimizing duration of participation in health promotion programs has important implications for program reach and costs. We examined data from 355 participants in EnhanceWellness (EW) to determine whether improvements in disability risk factors (depression, physical inactivity) occurred early or late in the enrollment period. Participants had a mean age of 74 years; 76% were women, and 16% were non-white. The percent depressed declined from enrollment to six months (35% to 28%, p = .001) and from six to 12 months (28% to 22%, p = .03). The percent physically inactive declined over the first six months, without substantial change thereafter (47%, 29%, and 29%). Those remaining inactive at six months had worse self-rated health and more depressive symptoms initially; a subset of those increased their physical activity by 12 months. These data suggest that enrollment could be reduced from 12 to six months without compromising favorable effects of EW participation, although additional benefits may accrue beyond six months.

Self-efficacy and self-management behaviors in patients with chronic kidney disease

Although past research has examined self-management among patients with end-stage renal disease (ESRD), little is known about self-management in patients with chronic kidney disease (CKD). In this cross-sectional survey (no intervention), 174 patients with CKD (serum creatinine > or =1.7 mg/dL) completed self-reported measures of self-efficacy, physical and mental functioning, and self-management. The purpose of the study was to explore the association between patients' perceived self-efficacy and their self-management behaviors. Five types of self-management behaviors were measured: communication with caregivers, partnership in care, self-care, self-advocacy, and medication adherence. Controlling for other relevant variables including age, education, diabetic status, hypertension, serum creatinine, physical functioning, and mental health functioning, higher perceived self-efficacy scores were associated with increased communication, partnership, self-care, and medication-adherence behaviors. In this study, patients' perceived self-efficacy was a more consistent correlate of self-management behavior than were demographic or health characteristics. Because self-management has been associated with positive patient outcomes, fostering self-management by supporting patient self-efficacy may have long-term benefits.

Self-management strategies to reduce pain and improve function among older adults in community settings: a review of the evidence

CONTEXT

Self-management strategies for pain hold substantial promise as a means of reducing pain and improving function among older adults with chronic pain, but their use in this age group has not been well defined.

OBJECTIVE

To review the evidence regarding self-management interventions for pain due to musculoskeletal disorders among older adults.

DESIGN

We searched the Medline and Cumulative Index to Nursing and Allied Health Literature databases to identify relevant articles for review and analyzed English-language articles that presented outcome data on pain, function, and/or other relevant endpoints and evaluated programs/strategies that could be feasibly implemented in the community. Abstracted information included study sample characteristics, estimates of treatment effect, and other relevant outcomes when present.

RESULTS

Retained articles (N = 27) included those that evaluated programs sponsored by the Arthritis Foundation and other programs/strategies including yoga, massage therapy, Tai Chi, and music therapy. Positive outcomes were found in 96% of the studies. Proportionate change in pain scores ranged from an increase of 18% to a reduction of 85% (median = 23% reduction), whereas change in disability scores ranged from an increase of 2% to a reduction of 70% (median = 19% reduction). Generalizability issues identified included limited enrollment of ethnic minority elders, as well as non-ethnic elders aged 80 and above.

CONCLUSIONS

Our results suggest that a broad range of self-management programs may provide benefits for older adults with chronic pain. Research is needed to establish the efficacy of the programs in diverse age and ethnic groups of older adults and identify strategies that maximize program reach, retention, and methods to ensure continued use of the strategies over time.

Self-care as a health resource of elders: an integrative review of the concept

AIM

To review the literature related to self-care and health promotion for elders and to develop an understanding of self-care as a health resource.

BACKGROUND

Self-care may improve health and prevent illness and disabilities in elders. Although studies of self-care are numerous, the significance of the concept as a health resource for elders lacks clarity. Before 1989, research focused principally on medical self-care at the expense of health care, and self-care was seen more as supplementary to professional health care rather than as a health-promoting approach in health care.

METHOD

In this integrative review from 2006, we selected theoretical and empirical articles published between 1990 and 2006, where self-care was related to elders' health promotion. Data were extracted from primary sources and included definitions of self-care, critical attributes, antecedents, goals and outcomes. We interactively compared data and display matrices to describe self-care as a health resource.

RESULTS

Fifty-seven articles addressed health self-care and were integrated into a framework of self-care as a health resource of elders. Self-care was identified as a two-dimensional construct including action capabilities and processes for health in self-care practice. The capabilities consisted of fundamental capabilities, power capabilities and performance capabilities. The action processes included a process of life experience, a learning process and an ecological process.

CONCLUSION

This review offers insight into self-care as a significant health resource of elders with different health status. It suggests that an elder's self-care ability is determined by the interaction of various sub-resources and conditions and emphasizes the constantly evolving nature of self-care. The framework may be of use in clinical practice, policy-making and research into health care of frail or robust elders.

Development, implementation and evaluation of a new adult asthma self-management program

The purpose of the research was to develop, implement, and evaluate a new adult asthma self-management program with a multidisciplinary perspective. Small groups of adults met for 2 hr for 7 consecutive weekly meetings. Participants were asked to practice asthma specific behaviors (including peak expiratory flow monitoring, avoidance/removal of asthma triggers, and controller medication adherence) and general lifestyle behaviors (including drinking water, practicing relaxation, washing hands, and exercising). Learner-centered teaching techniques such as interactive communication and social support were utilized to help participants practice self-management behaviors including problem-solving and goal-setting. Paired sample t-tests included statistically significant improvements in asthma knowledge, asthma specific quality of life (QOL), asthma specific behaviors such as peak flow monitoring and general life style behaviors such as frequency of daily exercise. These results provide evidence that this new adult asthma self-management program can lead to both knowledge acquisition and behavioral changes.

Unmet needs and treatment seeking in high users of mental health services: role of illness perceptions

OBJECTIVE

A small number of patients tend to use a disproportionately high amount of mental health services. Understanding the needs and behaviours of this group is important in order to improve patient management. Few studies have investigated the role that patients' perceptions about their mental illness play in guiding coping responses and treatment seeking. The aim of the present study was to investigate how illness perceptions in high users of mental health services were related to unmet needs and treatment-seeking behaviours.

METHOD

A total of 203 high users of mental health services were interviewed using the Brief Illness Perception Questionnaire, the Camberwell Assessment of Need and the Drug Attitude Inventory, and were also asked to report the number of visits they had made to the general practitioner in the past year. District Health Board clinical staff completed the Camberwell Assessment of Need and the Global Assessment of Functioning for each user.

RESULTS

More negative perceptions about mental illness were associated with higher ratings of unmet needs by both patients and staff. Negative perceptions were also related to poorer attitudes towards medication, and lower functioning. Perceptions about the personal ability to control the illness were consistently associated with better outcomes. Patients' causal attributions could be categorized as social, psychological, biological and behavioural. More frequent visits to the general practitioner were associated with perceptions of more severe symptoms, greater concern and higher emotional responses to the illness, and psychosocial causal attributions.

CONCLUSION

Illness perceptions provide a framework to assess patients' ideas about severe mental illness and a means by which to identify maladaptive beliefs. Interventions targeted at changing these beliefs may encourage better self-management.

Development and evaluation of a multimedia CD-ROM for exercise during pregnancy and postpartum

OBJECTIVE

To meet the need for an interactive product on exercise during pregnancy and postpartum, we developed and evaluated a personally tailored multimedia CD-ROM.

METHODS

Pregnant and postpartum women, who were randomly assigned to either the experimental group (PregXercise CD-ROM) or the control group (CD-ROM with neutral content), navigated through the CD-ROM for 1 h. Main outcomes were exercise self-efficacy and knowledge.

RESULTS

In analyses of covariance, compared with the control group, the experimental group had significant increases in self-efficacy and knowledge.

CONCLUSION

The multimedia CD-ROM delivering information about exercise motivation, guidelines, and prescription was effective in improving exercise self-efficacy and knowledge.

PRACTICE IMPLICATIONS

Our preliminary results illustrate that healthcare professionals and researchers may use interactive multimedia for improving exercise behavior and related outcomes with pregnant and postpartum women.

Patient-centered education: applying learner-centered concepts to asthma education

OBJECTIVE

To review studies of patient-centered asthma education.

METHOD

CINAHL, Medline, Psycinfo, Eric, PsycARTICLES, and web of science databases were searched. RESULTS Asthma education programs are often based on health behavior theories. Many studies lack rigor in the assessment of the program's efficacy and effectiveness. Asthma education that promotes self-management primarily uses a problem-based approach. Few studies have examined the way educators teach and patients learn. Patient-centered approaches to education have mainly focused on communication between the patient and the health professional. Decision making as part of shared responsibility may vary with every patient. Patient-centered care shares similarities with the Self-Determination Theory as a learner-centered approach to education.

CONCLUSIONS

Many asthma education studies have been completed with varying levels of efficacy and effectiveness reported. Most programs focus on changing behavior with few studies examining educator behavior and/or the patient's learning styles. With a patient-centered approach being the preferred model of care, the incorporation of learner-centered approaches to patient education may prove useful in the future.

Preferences for self-management support: findings from a survey of diabetes patients in safety-net health systems

OBJECTIVE

We sought to identify interest in different modes of self-management support among diabetes patients cared for in public hospitals, and to assess whether demographic or disease-specific factors were associated with patient preferences. We explored the possible role of a perceived communication need in influencing interest in self-management support.

METHODS

Telephone survey of a random sample of 796 English and Spanish-speaking diabetes patients (response rate 47%) recruited from four urban US public hospital systems. In multivariate models, we measured the association of race/ethnicity, primary language, self-reported health literacy, self-efficacy, and diabetes-related factors on patients' interest in three self-management support strategies (telephone support, group medical visits, and Internet-based support). We explored the extent to which patients believed that better communication with providers would improve their diabetes control, and whether this perception altered the relationship between patient factors and self-management support acceptance.

RESULTS

Sixty-nine percent of respondents reported interest in telephone support, 55% in group medical visits, and 42% in Internet. Compared to Non-Hispanic Whites, Spanish-speaking Hispanics were more interested in telephone support (OR 3.45, 95% CI 1.97-6.05) and group medical visits (OR 2.45, 95% CI 1.49-4.02), but less interested in Internet self-management support (OR 0.56, 95% CI 0.33-0.93). African-Americans were more interested than Whites in all three self-management support strategies. Patients with limited self-reported health literacy were more likely to be interested in telephone support than those not reporting literacy deficits. Forty percent reported that their diabetes would be better controlled if they communicated better with their health care provider. This perceived communication benefit was independently associated with interest in self-management support (p<0.001), but its inclusion in models did not alter the strengths of the main associations between patient characteristics and self-management support preferences.

CONCLUSION

Many diabetes patients in safety-net settings report an interest in receiving self-management support, but preferences for modes of delivery of self-management support vary by race/ethnicity, language proficiency, and self-reported health literacy.

PRACTICE IMPLICATIONS

Public health systems should consider offering a range of self-management support services to meet the needs of their diverse patient populations. More broad dissemination and implementation of self-management support may help address the unmet need for better provider communication among diabetes patients in these settings.

Use of computers and the Internet for health information by patients with epilepsy

The purpose of this study was to describe computer and Internet use among an online group and a clinic-based group of people with epilepsy. Greater than 95% of the online group and 60% of the clinic group have access to computers and the Internet. More than 99% of the online group and 57% of the clinic group used the Internet to find health information. A majority of people reported being likely to employ an Internet-based self-management program to control their epilepsy. About 43% reported searching for general information on epilepsy, 30% for medication, 23% for specific types of epilepsy, and 20% for treatment. This study found that people with epilepsy have access to computers and the Internet, desire epilepsy-specific information, and are receptive to online health information on how to manage their epilepsy.

Arthritis pain

Arthritic pain is a common and disabling problem for many older adults. There is widespread evidence that despite its prevalance and debilitating effects on the physical, emotional and cognitive status of older adults, arthritic pain remains under-treated in those age 65 and older. This condition significantly and negatively impacts older adults' quality of life and is a critical problem that requires the attention of gerontological social work. This chapter provides a brief summary of arthritic pain in older adults. It also discusses the treatment efficacy of cognitive-behavioral therapy and psycho-educational programs for older adults with this type of pain.

Results of a randomized controlled trial to examine the efficacy of a chronic pain self-management group for older adults [ISRCTN11899548]

Chronic pain is a common, disabling problem in older adults. Pain self-management training is a multimodal therapy that has been found to be effective in young to middle-aged adult samples; however, few studies have examined the effectiveness of this therapy in older adults. In this randomized, controlled trial, we evaluated a pain self-management training group (SMG) intervention as compared with an education-only (BOOK) control condition. Participants, 65 years of age or older who experienced persistent, noncancer pain that limited their activities, were recruited from 43 retirement communities in the Pacific Northwest of the United States. The primary outcome was physical disability, as measured by the Roland-Morris Disability Questionnaire. Secondary outcomes were depression (Geriatric Depression Scale), pain intensity (Brief Pain Inventory), and pain-related interference with activities (Brief Pain Inventory). Randomization occurred by facility to minimize cross-contamination between groups. Two-hundred and fifty-six individuals, mean age=81.8 (SD: 6.5), enrolled and 218 completed the study. No significant differences in outcomes were found between groups at post-intervention, 6-month follow-up, or 12-month follow-up. The SMG group showed a significantly greater increase over time, relative to the BOOK group, in two process measures, as measured by the Chronic Pain Coping Inventory: use of relaxation and use of exercise/stretching. In both cases, the increase was greatest from baseline to the post-intervention assessment. Study findings indicate that additional research is needed to determine the most effective content and delivery methods for self-management therapies targeted at older adults with chronic pain.

Self-management profiles and metabolic outcomes in type 2 diabetes

AIM

This paper reports a study whose aims were (1) to examine whether it is possible to determine participants' self-management profiles using three open-ended questions about their self-perceived role in diabetes management; and (2) to analyse whether such self-management profiles have any bearing on haemoglobin A(1c) levels.

BACKGROUND

The behavioural and educational aspects of self-management in type 2 diabetes have been the topic of a number of investigations. The individual's role in maintaining health and a satisfying everyday life with chronic conditions is increasingly becoming the focus of secondary prevention.

METHOD

Participants (n = 259) were recruited from those attending a year-long health educational programme for people with type 2 diabetes at Swedish pharmacies. A questionnaire was distributed 24 months after baseline. The health outcome, haemoglobin A(1c) was measured on four occasions. Three open-ended questions were used to explore self-management profiles based on perceived role, goal, and need of support in treatment. Data were collected during the period 1997-2002.

FINDINGS

The following profiles of participants emerged: Disease Manager, Compliant, and Disheartened, with no initial differences in metabolic control. However, during the programme Disease Managers achieved good glycaemic control and succeeded in maintaining the reduction in their blood glucose for a longer period than those in other categories: their haemoglobin A(1c) level was reduced by -0.35 at 6 months (P = 0.000), -0.30 at 12 months (P = 0.001), and -0.28 at 24 months (P = 0.001) after baseline. Compliant participants had a good everyday routine and a -0.18 reduction at 6 months (P = 0.028) but no statistically significant haemoglobin A(1c) level reduction later. A smaller group of people, the Disheartened, reported difficulties in living with diabetes and did not succeed in decreasing their haemoglobin A(1c) by statistically significant amounts.

CONCLUSION

Healthcare professionals could use our three open-ended questions to assist in understanding people's views of their role in disease management so that health promotion and education can be tailored to individual needs.

Feature selection and classification model construction on type 2 diabetic patients’ data

OBJECTIVE

Diabetes affects between 2% and 4% of the global population (up to 10% in the over 65 age group), and its avoidance and effective treatment are undoubtedly crucial public health and health economics issues in the 21st century. The aim of this research was to identify significant factors influencing diabetes control, by applying feature selection to a working patient management system to assist with ranking, classification and knowledge discovery. The classification models can be used to determine individuals in the population with poor diabetes control status based on physiological and examination factors.

METHODS

The diabetic patients' information was collected by Ulster Community and Hospitals Trust (UCHT) from year 2000 to 2004 as part of clinical management. In order to discover key predictors and latent knowledge, data mining techniques were applied. To improve computational efficiency, a feature selection technique, feature selection via supervised model construction (FSSMC), an optimisation of ReliefF, was used to rank the important attributes affecting diabetic control. After selecting suitable features, three complementary classification techniques (Naïve Bayes, IB1 and C4.5) were applied to the data to predict how well the patients' condition was controlled.

RESULTS

FSSMC identified patients' 'age', 'diagnosis duration', the need for 'insulin treatment', 'random blood glucose' measurement and 'diet treatment' as the most important factors influencing blood glucose control. Using the reduced features, a best predictive accuracy of 95% and sensitivity of 98% was achieved. The influence of factors, such as 'type of care' delivered, the use of 'home monitoring', and the importance of 'smoking' on outcome can contribute to domain knowledge in diabetes control.

CONCLUSION

In the care of patients with diabetes, the more important factors identified: patients' 'age', 'diagnosis duration' and 'family history', are beyond the control of physicians. Treatment methods such as 'insulin', 'diet' and 'tablets' (a variety of oral medicines) may be controlled. However lifestyle indicators such as 'body mass index' and 'smoking status' are also important and may be controlled by the patient. This further underlines the need for public health education to aid awareness and prevention. More subtle data interactions need to be better understood and data mining can contribute to the clinical evidence base. The research confirms and to a lesser extent challenges current thinking. Whilst fully appreciating the requirement for clinical verification and interpretation, this work supports the use of data mining as an exploratory tool, particularly as the domain is suffering from a data explosion due to enhanced monitoring and the (potential) storage of this data in the electronic health record. FSSMC has proved a useful feature estimator for large data sets, where processing efficiency is an important factor.

Stepped Care for Affective Disorders and Musculoskeletal Pain (SCAMP) study: design and practical implications of an intervention for comorbid pain and depression

OBJECTIVE

Depression and pain are common comorbid conditions that have reciprocal adverse effects on disability and treatment outcomes. The objective of this article is to describe a study that tests the effectiveness of a stepped-care approach using a combined medication-behavioral intervention.

METHOD

Stepped Care for Affective Disorders and Musculoskeletal Pain (SCAMP) is an NIMH-sponsored randomized clinical trial nested within a prospective cohort study. A total of 250 patients with clinically significant depression (PHQ-9 scores > or =10) and musculoskeletal pain of the lower back or legs (hip or knee) and 250 nondepressed patients with similar pain are enrolled, with baseline and serial follow-up assessments to be conducted over 12 months. The depressed patients are randomized to either a stepped-care intervention group or a usual-care control group. Stepped-care patients receive 12 weeks of optimized antidepressant management (Step 1) followed by six sessions of a pain self-management (PSM) program over the next 12 weeks (Step 2), all delivered by a nurse care manager who is supervised by a physician specialist. Approximately two thirds of the care manager contacts are by telephone.

RESULTS

The target sample of 500 subjects has been successfully enrolled, and randomization of the depressed patients has resulted in balanced groups of patients with moderately severe pain and depression. Mean SCL-20 depression severity in the clinical trial group is 1.9, with most meeting DSM-IV criteria for major depression (76.3%) and the rest having dysthymia only (18.4%) or minor depression (5.3%). Pain is about equally distributed between lower back (53%) and hip or knee (47%). A rational algorithmic approach to antidepressant selection and dosing, as well as an overview of the PSM program, is provided.

CONCLUSIONS

When completed, SCAMP will test whether optimized antidepressant management improves outcomes in patients with comorbid depression and pain and whether PSM produces additional benefits. The findings will be important for both primary care and mental health clinicians confronted by the prevalent depression-pain dyad.

Self-management education programmes by lay leaders for people with chronic conditions

BACKGROUND

Lay-led self-management programmes are becoming widespread in the attempt to promote self-care for people with chronic conditions.

OBJECTIVES

To assess systematically the effectiveness of lay-led self-management programmes for people with chronic conditions.

SEARCH STRATEGY

We searched: the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2005, Issue 1), MEDLINE (January 1986 to May 2006), EMBASE (January 1986 to June 2006), AMED (January 1986 to June 2006), CINAHL (January 1986 to June 2006), DARE (1994 to July 2006, National Research Register (2000 to July 2006), NHS Economic Evaluations Database (1994 to July 2006), PsycINFO (January 1986 to June 2006), Science Citation Index (January 1986 to July 2006), reference lists and forward citation tracking of included studies. We contacted principal investigators and experts in the field. There were no language restrictions.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing structured lay-led self-management education programmes for chronic conditions against no intervention or clinician-led programmes.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information. Results of RCTs were pooled using a random-effects model with standardised mean differences (SMDs) or weighted mean differences (WMDs) for continuous outcomes.

MAIN RESULTS

We included seventeen trials involving 7442 participants. The interventions shared similar structures and components but studies showed heterogeneity in conditions studied, outcomes collected and effects. There were no studies of children and adolescents, only one study provided data on outcomes beyond six months, and only two studies reported clinical outcomes.

PRIMARY OUTCOMES

Health status: There was a small, statistically-significant reduction in: pain (11 studies, SMD -0.10 (95% confidence interval (CI) -0.17 to -0.04)); disability (8 studies, SMD -0.15 (95% CI -0.25 to -0.05); and fatigue (7 studies, SMD -0.16 (95% CI -0.23 to -0.09); and small, statistically-significant improvement in depression (6 studies, SMD -0.16 95% CI -0.24 to -0.07). There was a small (but not statistically- or clinically-significant) improvement in psychological well-being (5 studies; SMD -0.12 (95% CI -0.33 to 0.09)); but no difference between groups for health-related quality of life (3 studies; WMD -0.03 (95% CI -0.09 to 0.02). Six studies showed a statistically-significant improvement in self-rated general health (WMD -0.20 (95% CI -0.31 to -0.10). Health behaviours: 7 studies showed a small, statistically-significant increase in self-reported aerobic exercise (SMD -0.20 (95% CI -0.27 to -0.12)) and a moderate increase in cognitive symptom management (4 studies, WMD -0.55 ( 95% CI -0.85 to -0.26)). Healthcare use: There were no statistically-significant differences between groups in physician or general practitioner attendance (9 studies; SMD -0.03 (95% CI -0.09 to 0.04)). There were also no statistically-significant differences between groups for days/nights spent in hospital (6 studies; WMD -0.32 (95% CI -0.71 to 0.07)). Self-efficacy: (confidence to manage condition) showed a small statistically-significant improvement (10 studies): SMD -0.30, 95% CI -0.41 to -0.19. No adverse events were reported in any of the studies.

AUTHORS' CONCLUSIONS

Lay-led self-management education programmes may lead to small, short-term improvements in participants' self-efficacy, self-rated health, cognitive symptom management, and frequency of aerobic exercise. There is currently no evidence to suggest that such programmes improve psychological health, symptoms or health-related quality of life, or that they significantly alter healthcare use. Future research on such interventions should explore longer term outcomes, their effect on clinical measures of disease and their potential role in children and adolescents.

Increasing physical exercise levels: age-specific benefits of planning

PURPOSE

This study examines the differential age effects on physical exercise of two planning interventions, action planning (when, where, how) and coping planning (anticipating barriers, mental simulation of success scenarios), and examines the mediating mechanisms of the interventions.

METHODS

The study assigned the participants, 205 cardiac rehabilitation patients, to one of the intervention groups (action-planning only or combined-planning group) or to a control group. Baseline measurement and follow-up took place 2 months apart.

RESULTS

The interventions enhanced physical exercise independently of age. Pretreatment coping planning was higher in older (65-82 years) than in younger (38-54 years) or middle-aged (55-64 years) participants. At Time 2, older participants were the only ones without further increase in coping planning. Advancement in coping planning partially mediated the effect of the intervention.

CONCLUSION

Coping planning facilitates improvement of physical exercise. Implications of age differences in planning are discussed.

A 6-item brief measure for assessing perceived control of asthma in culturally diverse patients

BACKGROUND

A concise yet accurate measurement tool is needed for use in research and practice in asthma self-management perceptions across culturally diverse patient populations.

OBJECTIVES

To evaluate the psychometric properties of the 11-item Perceived Control of Asthma Questionnaire (PCAQ) and to derive a brief, psychometrically sound, and culturally sensitive measure using item response theory.

METHODS

The PCAQ was administered as one of a battery of measures to 375 adults with asthma as part of an ongoing larger project studying asthma disparities. Analyses of differential item functioning (DIF) were conducted to detect the effects of sex, race/ethnicity, and health literacy on psychometric properties.

RESULTS

Forty-eight percent of the sample was non-Hispanic white and 44% was African American. The mean +/- SD age was 43.7 +/- 13.7 years. The derived 6-item version, with 5 DIF items not scored, correlated highly with its full version (r = 0.903; P < .001).

CONCLUSIONS

The 6-item PCAQ short form has the potential to maintain scale integrity while reducing administration time and lessening survey fatigue in studies using multiple questionnaires. DIF analyses also enabled us to understand the unique aspects of perceived asthma control in demographic groups most affected by asthma.
