Abstract
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide and, although it is a preventable and treatable disease, it often remains undiagnosed in patients with mild disease. It is now evident that pathologic changes and physiologic impairment start early in disease progression, and even patients with mild airflow limitation have impairment in the form of exertional dyspnea, general fatigue, and exercise intolerance. Primary care physicians are optimally positioned to recognize these progressive activity restrictions in their patients, usually involving little more than a detailed patient history and a simple symptom questionnaire. Once a patient with persistent activity-related dyspnea has been diagnosed with COPD, bronchodilators can effectively address expiratory airflow limitation and lung hyperinflation that underlie symptoms. These pharmacologic interventions work in conjunction with nonpharmacologic interventions, including smoking cessation, exercise training, and pulmonary rehabilitation. Although the benefits of exercise intervention are well established in patients with more severe COPD, a small amount of new data is emerging that supports the benefits of both pharmacologic treatment and exercise training for improving exercise endurance in patients with mild-to-moderate COPD. This review examines the growing body of data that suggests that early identification-most likely by primary care physicians-and appropriate intervention can favorably impact the symptoms, exercise tolerance, health status, quality of life, hospitalizations, and economic costs of COPD.

Abstract
Purpose Although chronic obstructive pulmonary disease (COPD) primarily affects the lungs, it is regarded as a systemic disorder associated with comorbidity and physical deterioration, which often results in reduced levels of health-related quality of life (HRQoL). Self-efficacy is an important concept in self-management, which is vital for improving HRQoL in patients with COPD. The purpose of this study was to examine how general self-efficacy, leisure time physical activity, and sociodemographic variables such as employment status are related to the physical and mental health components of HRQoL in patients with COPD. Patients and methods In this cross-sectional study, 97 COPD patients (54.6% male, mean age 64.6 years, standard deviation [SD] 9.5) beginning a pulmonary rehabilitation program completed three self-report questionnaires: the short form (SF)-12v2 Health Survey as a measure of HRQoL; the General Self-Efficacy Scale; and a standardized instrument measuring regular leisure time physical activity. Results The physical health component median score was 31.3 (interquartile range [IQR] 16.3) and the mental health component median score was 45.9 (IQR 21.5). Two sets of linear regression analyses were performed, one predicting physical health and the other predicting mental health. The first analysis showed that better physical health was directly related to being in paid work (P-value <0.001), but was not significantly related to age, sex, marital status, education, work status, physical activity, or self-efficacy. In the second analysis, better mental health was directly related to living with a partner, being physically active, and having higher self-efficacy (P-value <0.001). Conclusion The findings suggest that general self-efficacy has differential relationships to the two dimensions of HRQoL. Our results indicate that general self-efficacy, physical activity, and paid work might be important factors for improving HRQoL of persons with COPD, and should be taken into consideration in pulmonary rehabilitation.

Abstract
BACKGROUND The objectives of this systematic review were to synthesize the literature on measures of activities of daily living (ADLs) that have been used in individuals with COPD and to provide an overview of the psychometric properties of the identified measures and describe the relationship of the disease-specific instruments with other relevant outcome measures for individuals with COPD and health-care use. METHODS Studies that included a measure of ADLs in individuals with COPD were identified using electronic and hand searches. Two investigators performed the literature search. One investigator reviewed the study title, abstract, and full text of the articles to determine study eligibility and performed the data extraction and tabulation. In cases of uncertainty, a second reviewer was consulted. RESULTS A total of 679 articles were identified. Of those, 116 met the inclusion criteria. Twenty-seven ADLs instruments were identified, of which 11 instruments were respiratory disease-specific, whereas 16 were generic. Most instruments combined instrumental ADLs (IADLs) with basic ADLs (BADLs). The majority of the instruments were self-reported; only three instruments were performance based. Twenty-one studies assessed psychometric properties of 16 ADLs instruments in patients with COPD. CONCLUSIONS Although several ADLs instruments were identified, psychometric properties have only been reported in a few. Selection of the most appropriate measure should focus on the target construct (BADLs or IADLs or both), type of test (disease-specific vs generic and self-reported vs performance-based), depth of information obtained, and psychometric properties of the instruments. Given the relevance of ADLs to the lives of patients with COPD, its assessment should be more frequently incorporated as a clinical outcome in their management.

Abstract
OBJECTIVES To assess the prevalence of chronic respiratory conditions in metropolitan fire-fighters and to study associations between occupational exposure, use of respiratory protection and health-related quality of life (HRQoL) in fire-fighters with and without chronic respiratory conditions. METHODS Cross-sectional cohort analysis: Respiratory symptoms, medical conditions, occupational tasks and exposures and consistency of using respiratory protection were inquired by questionnaire. The SF12(®)V2 Health Survey was used to measure physical (PCS-12) and mental (MCS-12) HRQoL. Fire-fighters were categorised in subgroups: asthma; COPD/emphysema/chronic bronchitis; no chronic respiratory conditions; and as being 'not involved' or 'involved' in fire-fighting tasks, the latter further categorised as 'consistent' or 'inconsistent' use of respiratory protection. PCS-12 and MCS-12 scores were compared between subgroups and categories using linear regression. RESULTS Five hundred and seventy fire-fighters were analysed, 24 (4%) fulfilled the criteria for asthma, 39 (7%) for COPD/emphysema/chronic bronchitis. Fire-fighters with asthma were older than those in the other two subgroups and had been employed in the fire service longer. Respiratory subgroups did not differ in their involvement in fire-fighting tasks. Ninety-one percent of fire-fighters reported relevant occupational exposure in the past year. Mean PCS-12 scores for fire-fighters with no chronic respiratory conditions, asthma and COPD/emphysema/bronchitis were 52.0 (SD 6.9), 47.0 (8.5) and 48.1 (9.4). For PCS-12 (but not for MCS-12), interaction between having a chronic respiratory condition and inconsistent use of respiratory protection during fire knockdown was observed (p < 0.001). CONCLUSIONS Ten percent of metropolitan fire-fighters reported underlying chronic respiratory conditions. Presence of such a condition in combination with suboptimal protection from inhaled exposures may lead to poorer physical HRQoL.

Abstract
Coping with breathlessness is a complex and multidimensional challenge for people with chronic obstructive pulmonary disease (COPD) and involves interacting physiological, cognitive, affective, and psychosocial dimensions. The aim of this study was to explore how people with moderate to most severe COPD predominantly cope with breathlessness during daily living. We chose a multi-modal grounded theory design that holds the opportunity to combine qualitative and quantitative data to capture and explain the multidimensional coping behaviour among people with COPD. The participants’ main concern in coping with breathlessness appeared to be an endless striving to economise on resources in an effort to preserve their integrity. In this integrity-preserving process, four predominant coping types emerged and were labelled: ‘Overrater’, ‘Challenger’, ‘Underrater’, and ‘Leveller’. Each coping type comprised distinctive physiological, cognitive, affective and psychosocial features constituting coping-type-specific indicators. In theory, four predominant coping types with distinct physiological, cognitive, affective and psychosocial properties are observed among people with COPD. The four coping types seem to constitute a coping trajectory. This hypothesis should be further tested in a longitudinal study.

Abstract
INTRODUCTION Individuals with chronic obstructive pulmonary disease (COPD) experience irreversible airflow obstruction, dyspnea, coughing, and fatigue. One of the goals of treating individuals with COPD is to improve their quality of life. The aim of this research was to evaluate the 2009 Texas Behavioral Risk Factor Surveillance System (BRFSS) as a method for surveillance of COPD by identifying factors associated with impaired health-related quality of life (HRQoL) among respondents with COPD as well as comment on differences between the COPD and non-COPD population in a state representative sample. METHOD Data from 348 COPD respondents were obtained from the 2009 Texas BRFSS. The Andersen behavior model was used to categorize variables as predisposing characteristics, health behaviors, and health service utilization. Self-rated health (SRH) was the HRQoL indicator used in this analysis. Chi-square tests were used to examine differences between COPD and non-COPD respondents. The relation between SRH and risk factors were modeled using domain analysis and logistic regressions. All analyses incorporated the sample weights to be representative of the state population. RESULTS Adults with COPD reported significantly worse SRH than adults who did not have COPD (p < .001). Among respondents with COPD, the predisposing characteristics associated with impaired HRQoL were obesity, education, and asthma; the health practices and service utilization factors associated with HRQoL included smoking, physical inactivity, having a health plan, and the inability to see a doctor because of costs. CONCLUSIONS The Texas COPD population experienced increased risk of impaired SRH compared with the non-COPD population. The findings from our population-level survey study are similar to results observed at the clinical level.

Abstract
Conventional methods have not yet succeeded in capturing the complexity of how people with chronic obstructive pulmonary disease (COPD) cope with breathlessness during daily living. We used a multi-modal grounded theory (GT) approach to investigate coping. In this paper, we describe and evaluate the multi-modal GT approach, which encompasses videos of daily life activity, interviews, medical history, demographics, self-rated sensation of breathlessness, and physiological measurements. A formative evaluation was conducted according to the criteria that the data collection should strengthen the participants’ ability to remember and narrate how they cope with breathlessness; capture the multidimensional aspects involved in coping with breathlessness; encompass tools for collecting both qualitative and quantitative data, providing the opportunity to generate, synchronize, and combine data; and be ethically justifiable. The approach should also be consistent with the GT methodology of generating a theory. Striving to develop and perfect the multi-modal GT approach was time-consuming. Apart from this practical challenge, the multimodal GT approach met all evaluation criteria. This approach has the potential to generate new knowledge and may become an important methodological contribution towards understanding the multidimensionality of coping with breathlessness.

Abstract
PURPOSE The purpose of this study was to delineate the effect of chronic obstructive pulmonary disease (COPD) on a broad range of valued life activities (VLAs) and make comparisons to effects of other airways conditions. METHODS We used cross-sectional data from a population-based, longitudinal study of US adults with airways disease. Data were collected by telephone interview. VLA disability was compared among 3 groups defined by reported physician diagnoses: COPD/emphysema, chronic bronchitis, and asthma. Multiple regression analyses were conducted to identify independent predictors of VLA disability. RESULTS About half of individuals with COPD were unable to perform at least 1 VLA; almost all reported at least 1 VLA affected. The impact among individuals with chronic bronchitis and asthma was less but still notable: 74%-84% reported at least 1 activity affected, and about 15% were unable to perform at least 1 activity. In general, obligatory activities were the least affected. Symptom measures and functional limitations were the strongest predictors of disability, independent of respiratory condition. CONCLUSION VLA disability is common among individuals with COPD. Obligatory activities are less affected than committed and discretionary activities. A focus on obligatory activities, as is common in disability studies, would miss a great deal of the impact of these conditions. Because individuals are often referred to pulmonary rehabilitation as a result of dissatisfaction with ability to perform daily activities, VLA disability may be an especially relevant outcome for rehabilitation.

Abstract
BACKGROUND Both disability and depression are common in COPD, but limited information is available on the time-ordered relationship between increases in disability and depression onset. METHODS Subjects were members of a longitudinal cohort with self-reported physician-diagnosed COPD, emphysema, or chronic bronchitis. Data were collected through three annual structured telephone interviews (T1, T2, and T3). Depression was defined as a score >/= 4 on the Geriatric Depression Scale Short Form (S-GDS). Disability was measured with the Valued Life Activities (VLA) scale; three disability scores were calculated: percent of VLAs unable to perform, percent of VLAs affected (unable to perform or with some degree of difficulty), and mean VLA difficulty rating. Disability increases were defined as a 0.5 SD increase in disability score between T1 and T2. Multiple logistic regression analyses estimated the risk of T3 depression following a T1 to T2 disability increase for the total cohort and then excluding individuals who met the depression criterion at T1 or T2. RESULTS Approximately 30% of subjects met the depression criterion each year. Eight percent to 19% experienced a T1 to T2 disability increase, depending on the disability measure. Including all cohort members and controlling for baseline S-GDS scores, T1 to T2 increases in disability yielded a significantly elevated risk of T3 depression (% affected odds ratio [OR] =3.6; 95% CI, [1.7, 7.7]; % unable OR = 6.1 [17, 21.8]; mean difficulty OR= 3.6 [1.7, 8.0]). Omitting individuals depressed at T1 or T2 yielded even stronger risk estimates for % unable (OR = 13.4 [2.0, 91.4]) and mean difficulty (OR = 3.9 [1.3, 11.8]). CONCLUSIONS Increases in VLA disability are strongly predictive of the onset of depression.

Abstract
BACKGROUND The objective of this study was to measure health-related quality of life (HRQL) in outpatients with chronic obstructive pulmonary disease (COPD) and to assess differences in HRQL according to age, gender, and severity of COPD. METHODS A total of 9405 patients (79% men, mean age 68 years) participated in a cross-sectional study. HRQL was measured with the Short Form 12 Health Survey Questionnaire (SF-12). Severity of COPD was graded into three levels according to forced expiratory volume in one second value. RESULTS COPD severity was mild in 33.8% of cases, moderate in 49.3% and severe in 16.8%. The mean physical component summary (PCS-12) and mental component summary (MCS-12) scores were 36.8 +/- 10.4 and 47.2 +/- 11.2, respectively. General health and physical functioning domains were those with the lowest scores. The mean MCS-12 scores were significantly higher in men (47.9 +/- 10.9) than in women (44.1 +/- 11.8) (P < 0.001). Patients older than 60 years rated HRQL worse than patients aged 40-59 years. There were statistically significant differences according to severity of disease in the mean scores of all domains of the PCS-12 and MCS-12 scales. CONCLUSIONS The present findings show the influence of female gender, older age and moderate-to-severe of airflow limitation on HRQL in outpatients with COPD attended in daily practice.

Abstract
BACKGROUND The Burden of Obstructive Lung Disease (BOLD) initiative provides a standardized way of measuring the prevalence of COPD. METHODS We used the BOLD survey to estimate the prevalence of COPD in adults aged >or= 40 years in a target population of 325,000 in Southeastern Kentucky. Testing was done at survey centers and homes and included questionnaires on respiratory symptoms, risk factors for COPD, and health status. Postbronchodilator spirometry was used to classify subjects. We determined the prevalence of COPD along with the relation of COPD and comorbid disease and physical and mental quality of life measures. RESULTS The final study population was 508, with a participation response rate of 25.2%. Overall, 19.6% of subjects met criteria for Global Initiative for Chronic Obstructive Lung Disease stage 1 or higher COPD, and an additional 17.6% met criteria for restriction. Diabetes, heart disease, and hypertension were significantly increased in subjects with restriction. Physical quality of life was significantly decreased in all respiratory impairment categories, compared to normal subjects, whereas mental quality of life measures were not affected. CONCLUSIONS In this population, respiratory impairment is highly prevalent and associated with comorbid disease and physical, but not mental, dysfunction.

Abstract
BACKGROUND Although self-care may reduce exacerbations of heart failure, reported rates of effective self-care in patients with heart failure are low. Modifiable factors, including psychosocial status, knowledge, and physical factors, are thought to influence heart failure self-care, but little is known about their combined impact on self-care. OBJECTIVES The objective of this study was to identify factors related to self-care behaviors in patients with heart failure. DESIGN A cross-sectional, correlational study design was used. PARTICIPANTS AND SETTINGS One hundred twenty-two patients (77 men and 45 women, mean age 60+/-12 years old, 66% New York Heart Association functional class III/IV) were recruited from the outpatient clinics of an academic medical center and two community hospitals. METHODS Data on self-care behaviors (Self-Care of Heart Failure Index), depressive symptoms, perceived control, self-care confidence, knowledge, functional status, and social support were collected. Factors related to self-care were examined using hierarchical multiple regression. RESULTS Mean self-care behavior scores were less than 70 indicating the majority of men and women with HF did not consistently engage in self-care behaviors. Higher self-care confidence and perceived control and better heart failure management knowledge were associated with better self-care (r2=.25, p<.001). Higher perceived control and better knowledge were related to better self-care behaviors in men (r2=.18, p=.001), while higher self-care confidence and poorer functional status were related to better self-care behaviors in women (r2=.35, p<.001). CONCLUSION This study demonstrates the substantial impact of modifiable factors such as confidence in one's self-care abilities, perceived control, and knowledge on self-care behaviors. This study demonstrates that there are gender differences in factors affecting self-care, even though at baseline men and women have similar knowledge levels, physical, psychological, and behavioral status. Effective interventions focusing on modifiable factors and the unique characteristics of men and women should be provided to improve self-care behaviors in patients with heart failure.

Abstract
This Review discusses physiological, emotional, behavioural, and cognitive aspects of psychological adjustment to chronic illness. Reviewing the reports of the past decade, we identify four innovative and promising themes that are relevant for understanding and explaining psychological adjustment. In particular, the emphasis on the reasons why people fail to achieve a healthy adjustment has shifted to the identification of factors that help patients make that adjustment. To promote psychological adjustment, patients should remain as active as is reasonably possible, acknowledge and express their emotions in a way that allows them to take control of their lives, engage in self-management, and try to focus on potential positive outcomes of their illness. Patients who can use these strategies have the best chance of successfully adjusting to the challenges posed by a chronic illness.

Abstract
OBJECTIVE To identify the prevalence of disability in a wide range of valued life activities (VLAs) among individuals with systemic lupus erythematosus (SLE), 1-year changes in such disability, and predictors of and changes in VLA disability. METHODS Data were from 2 waves of a cohort of 829 individuals with SLE interviewed annually by telephone. VLA disability was assessed using a scale rating the difficulty of performing 21 activities. Scores were also calculated for subscales corresponding to obligatory, committed, and discretionary activities. Changes in VLA disability from baseline to 1-year followup were assessed. Sociodemographic and disease status measures were examined as predictors of and changes in VLA disability using multiple regression analyses. RESULTS Almost half of the subjects were unable to perform > or =1 VLA at baseline. Almost all (91%) reported > or =1 VLA affected by SLE. One-quarter of the subjects experienced a significant increase in the number of activities they were unable to perform; approximately half experienced significant increases in the number of activities affected and in difficulty scores. Proportions of individuals whose disability increased and whose disability decreased were roughly equivalent. Disease status measures accounted for 62-72% of the variation in VLA difficulty. More severe disease status was predictive of increases in VLA difficulty; few predictors of improvements were identified. CONCLUSION VLA disability was common, with more disability noted in committed and discretionary activities than in obligatory activities. Because VLA disability has been linked to psychological well-being in previous studies, identification of factors that may protect against such disability is important.
