“…There is a strong background of research in our department involving physiotherapists, occupational therapists, nurses and doctors. The incremental and endurance shuttle walk tests and a self-administered form of the Chronic Respiratory Disease Questionnaire were developed through projects at Glenfield Hospital [17][18][19]. We are able to recruit large numbers of subjects into clinical trials due to the size of our rehabilitation programme.…”

WINNING ABSTRACT: We conducted a randomised, placebo-controlled trial to examine whether creatine supplementation augments the benefits of pulmonary rehabilitation (PR), containing aerobic exercise and resistance training (RT).80 subjects with COPD (GOLD stages I-IV) [mean (SD) age 68 (7.8) yrs, FEV 1 44.1 (20.3) % predicted] completed 21 sessions of PR, with enhanced RT, following baseline measurements and randomisation to take creatine (Cr) or placebo (Pl) supplement. A subgroup had muscle biopsies.Groups were well matched at baseline except for gender

“…Health-related quality of life (HRQL) was measured with the physical and mental composite scores of the generic SF-12 (12-item Short Form Health Survey) (17) and the dyspnea domain of the Chronic Respiratory Questionnaire (CRQ) (18). The physical and mental composite scores of the SF-12 range from 0 to 100, where the general population scores are centered at 50; higher scores suggest higher HRQL (17,19).…”

Domain-Specific Self-Efficacy Is Associated with Measures of Functional Capacity and Quality of Life among Patients with Moderate to Severe Chronic Obstructive Pulmonary Disease

The relationship between self-efficacy and health behaviors is well established. However, little is known about the relationship between self-efficacy and health-related indicators among patients with chronic obstructive pulmonary disease (COPD).Objectives: The purpose of this cross-sectional cohort study was to test the hypothesis that the total score and specific subdomain scores of the COPD Self-Efficacy Scale (CSES) are associated with functional capacity and quality of life in a group of patients with moderate to severe COPD.Methods: Relationships were examined in a cross-sectional study of baseline data collected as part of a randomized trial. Self-efficacy was measured using the five domains of the CSES: negative affect, emotional arousal, physical exertion, weather/environment, and behavioral. Measures of quality of life and functional capacity included SF-12: physical and mental composite scores, Chronic Respiratory Questionnaire dyspnea domain, and the 6-minutewalk test. Statistical analyses included Spearman correlation and categorical analyses of self-efficacy ("confident" vs. "not confident") using general linear models adjusting for potential confounders.Measurements and Main Results: There were 325 patients enrolled with a mean age (standard deviation) of 68.5 (9.48) years, 49.5% male, and 91.69% non-Hispanic white. The negative affect, emotional arousal, and physical exertion domains were moderately correlated (range, 0.3-0.7) with the SF-12 mental composite score and Chronic Respiratory Questionnaire dyspnea domain. In models exploring each CSES domain as "confident" versus "not confident" and adjusting for age, sex, race, pack-years, and airflow obstruction severity, there were multiple clinically and statistically significant associations between the negative affect, emotional arousal, and physical exertion domains with functional capacity and quality of life. Conclusions:The aggregated total CSES score was associated with better quality of life and functional capacity. Our analysis of subdomains revealed that the physical exertion, negative affect, and emotional arousal subdomains had the largest associations with functional capacity and quality of life indicators. These findings suggest that interventions to enhance self-efficacy may improve the functional capacity and quality of life of patients with moderate to severe COPD.Keywords: COPD; dyspnea; self-efficacy; quality of life Author Contributions: B.E.J., D.B.C., J.A., K.P.S., and S.B. were involved in the conception, hypothesis generation, and design of the study.

“…The CRQ asks the patient to rate how often in the last 2 weeks has had a particular feeling or experience on a scale of 1-7, with higher ratings indicating less symptom-related impairment. The CRQ has shown good validity and high internal consistency reliability (37). Its test-retest reliability is adequate in all subscales, but its reliability is particularly high in the subscales of fatigue (r = 0.90), emotion (r = 0.93), and mastery (r = 0.91) (37).…”

Emotional Intelligence: A Novel Outcome Associated with Wellbeing and Self-Management in Chronic Obstructive Pulmonary Disease

Rationale: Individuals with chronic obstructive pulmonary disease (COPD) often struggle with diminished autonomy and quality of life. Emotional factors play a crucial role in the well-being of patients with COPD; they are independently associated with critical outcomes such as dyspnea, quality of life, and health care use. Emotional intelligence is the capacity to understand and manage personal thoughts and feelings, as well as to positively influence interpersonal communication and social well-being. Emotional intelligence is a trainable skill that is extensively used in corporate business to improve well-being and performance, and it may also be significant in the self-management of emotions in patients with chronic disease. Importantly, research supports the proposition that emotional intelligence may be developed and learned at any time or any age, and training programs have been associated with increased well-being and better emotional regulation in patients with chronic disease. However, to date, no research has been done to investigate its value in patients with COPD.Objectives: We aimed to investigate the association between emotional intelligence and two meaningful outcomes in COPD: quality of life and self-management abilities.Methods: Participants with moderate to severe COPD completed a disease-specific quality of life tool (Chronic Respiratory Questionnaire), the Trait Emotional Intelligence Questionnaire, the Self-Management Abilities Scale, the modified Medical Research Council Dyspnea Scale, and pulmonary function tests, and also provided information about living conditions and self-reported health care use. Measurements and Main Results:A total of 310 patients with COPD (mean age, 69 6 9 yr; 40% female; mean FEV 1 %, 42.4 6 15.8) participated in the study. Emotional intelligence was significantly and independently associated with self-management abilities (P , 0.0001) and all domains of quality of life assessed (dyspnea, fatigue, emotions, and mastery; P , 0.0001) after adjusting for age, degree of bronchial obstruction, breathlessness, and other significant confounders.Conclusions: Emotional intelligence may represent an important attribute in COPD, as it is associated with self-management abilities and all domains of quality of life, regardless of age or disease severity. Emotional intelligence can be learned and may complement existing rehabilitation efforts. Attention to it may address the current gap that exists in the treatment of emotional components of COPD responsible for decreased quality of life and increased health care use.Keywords: chronic obstructive pulmonary disease; emotional intelligence; emotions; quality of life; self-management Author Contributions: R.P.B.: contributed to the conception and design of the work as well as the analysis and interpretation of data; J.L.K.: contributed to the analysis and interpretation of the data; and M.M.D. and B.A.-B.: contributed to the design of the study.
