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.

“…Selfefficacy maintain function concerns the confidence patients have in being able to engage in physical activities. As a result of low perceptions of self-efficacy, COPD patients may refrain from the activities of daily life [58]. Increased perceptions of self-efficacy maintain function may encourage patients to engage in social activities more often, which in turn may enhance their feelings of well-being.…”

“…[15][16][17][18][19][20][21] Very little work has examined how patient outcome expectations impact medication adherence and disease-specific self-management behaviours. 22 Instruments to assess self-efficacy and outcome expectations have been developed and used in various chronic conditions, such as hypertension, asthma, osteoporosis, and arthritis [22][23][24][25][26][27][28][29][30] , but to our knowledge, no instrument exists for measuring self-efficacy in relation to the use of glaucoma medications. Therefore, the purpose of this study was to develop and evaluate the psychometric properties of (a) a glaucoma medication self-efficacy scale and (b) a glaucoma outcome expectations scale.…”

Purpose The purpose of this study was to develop and evaluate the psychometric properties of (a) a glaucoma medication selfefficacy scale and (b) a glaucoma outcome expectations scale.Patients and Methods Two instruments were developed: a glaucoma medication selfefficacy scale and a glaucoma outcome expectations scale. Packets containing (a) the instruments and patient demographic questions and (b) a letter explaining the study were distributed to 225 glaucoma patients from three ophthalmology practices between August and December 2007. The instrument was completed by 191 patients for a response rate of 85%. Principal components factor analysis with a varimax rotation and Cronbach's a reliability were used to analyse the data. To assess discriminant validity, we administered the scales and two self-reported measures of adherence in a separate sample of 43 glaucoma patients who were currently using at least one glaucoma medication.Results Our results yielded a 21-item self-efficacy in overcoming barriers that might interfere with the use of glaucoma medications scale, a 14-item self-efficacy in carrying out specific tasks required to use eye drops correctly scale, and a four-item glaucoma outcome expectations scale. Results of the Cronbach's a reliability indicated that the scales are internally consistent. The selfefficacy scales were both significantly associated with two patient self-reported measures of glaucoma medication adherence, which show discriminant validity.Conclusions Eye care providers and researchers can use these scales to identify patients with low self-efficacy in using their glaucoma medications and patients who do not believe that following their eye care providers' advice can help their vision.
