Purpose: Although it is well-known that persons with COPD experience lower health related quality of life (HRQoL), little is known about the importance of self-management related domains on HRQoL in persons with COPD. Therefore, the purpose of this study is to examine associations between self-management related domains and HRQoL, adjusting for sociodemographic and clinical characteristics, self-efficacy, and sense of coherence.
Methods: Cross-sectional data of 225 persons with COPD, recruited from a hospital register, were analyzed. Self-management related domains were measured using the Health education impact questionnaire (heiQ) and HRQoL was measured using the St. George's Respiratory Questionnaire (SGRQ). Multiple linear regression analysis was used.
Results: The final models showed significant associations between the self-management domains constructive attitudes and approaches and emotional distress and HRQoL. Dyspnea, number of comorbidities, self-efficacy, and the various self-management related domains explained 51.3 to 55.1% of the variance in HRQoL.
Conclusions: The findings suggest that addressing self-management related domains, in addition to self-efficacy, dyspnea, and comorbidities, may be of importance for enhancement of HRQoL in persons with COPD.
