Chronic Obstructive Pulmonary Disease
Conditions
Brief summary
People with chronic obstructive pulmonary disease (COPD) are very sedentary and efforts to establish an active lifestyle are challenging because of periodic acute exacerbations of COPD that interrupt physical activity patterns and contribute to further decline in physical activity. The purpose of this preliminary research is to learn more about the experience of acute exacerbations of COPD (AECOPD) from the perspective of the patient and his/her family and to learn how AECOPDs affect physical activity.
Detailed description
Individuals with chronic obstructive pulmonary disease (COPD) are very sedentary and their physical activity is often interrupted by acute exacerbations of COPD (AECOPD). Little is known about the expectations had by individuals with COPD and the effects of these expectations on their physical activity. To increase the understanding of these expectations in people with COPD, a study is proposed to explore their experience of daily fluctuations in symptoms and AECOPDs, focusing on how these experiences influence health promoting behaviors, especially physical activity (PA). This study will involve an enrollment visit during which consent will be obtained, survey data will be administered (that they may take home), spirometry testing will be conducted, and a physical activity monitor (ActivPAL device) will be applied to be worn one week to allow us to understand their usual PA. A clinical ethnographic interview will then be conducted one week following enrollment, at which point the questionnaires and ActivPAL device will be collected. A second clinical ethnographic interview will be conducted one week following the first. Survey data will again collected at week 15 by mail.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Physical activity during AECOPD | week 1 | Subjects will be asked to report how they managed their physical activity during the last AECOPD. Current physical activity will be measured with accelerometry and by the CHAMPS questionnaire. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Sense of coherence | week 1 and week 15 | Questionnaire that measures one's global orientation to life and the extent to which one sees life as comprehensible, manageable and meaningful. |
| Barriers efficacy scale | week 1 week 15 | Questionnaire that measures barriers to exercise and physical activity. The subjects reports the level of confidence they have that they can overcome each barrier. |
| Help seeking behavior | week 1 and week 15 | Questionnaire assesses help seeking with respect to healthcare services. |
| COPD Stigma Scale | week 1 and week 15 | Questionnaire measures the stigma associated with having COPD. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Social Support for Exercise | week 1 | Questionnaire measures social support, positive and negative social influences for physical activity and social support for exercise. |
| COPD symptoms | week 1 | Questionnaire, the COPD Assessment Tests quantifies severity of the most recent exacerbation. |
