Health Literacy, Physical and Cognitive Function, Health-related Behaviors, and Quality of Life in COPD

Functional capacity assessment using self-paced 6-minute walk test.

Test of Functional Health Literacy in Adults will be used to evaluate health literacy. The TOFHLA is scored on a scale of 0 to 100 and higher scores indicate higher health literacy.

The Rapid Estimate of Adult Literacy in Medicine questionnaires will be performed. A score of 59 or less is defined as indicating low health literacy and a score of 60 or more indicates adequate health literacy.

Montreal Cognitive Assessment will be used to evaluate cognitive function. The Montreal Cognitive Assessment scores range between 0 and 30. A score of 26 or over is considered to be normal.

Health-related Behavior Scale II will be performed to assess health-related behavior. The Health-related Behavior Scale II measures various health-related behaviors and is designed to assess the frequency or extent of engagement in these behaviors. Higher scores of the scale indicate more frequent or healthier behaviors, depending on the specific behavior being measured.

One-minute sit to stand test will be performed. The number of repetitions will be recorded.

Pulmonary function test using a spirometer will be performed. Forced vital capacity will be recorded.

Pulmonary function test using a spirometer will be performed. Forced expiratory volume in one second will be recorded.

Pulmonary function test using a spirometer will be performed. Forced expiratory volume in one second/forced vital capacity ratio will be recorded.

Pulmonary function test using a spirometer will be performed. Peak expiratory flow will be recorded.

Pulmonary function test using a spirometer will be performed. Forced mid-expiratory flow (FEF25-75) will be recorded.

Physical activity will be evaluated with International Physical Activity Questionnaire questionnaire. The questionnaire assesses physical activity across different domains, including leisure time, domestic and gardening activities, work-related activities, and transport-related activities. Scores are calculated based on the duration (minutes) and frequency (days) of these activities over the past seven days. Higher scores on the IPAQ indicate a higher level of physical activity.

St. George quality of life questionnaire will be used to assess quality of life. Higher scores reflect worse health status.

Activities of daily living will be evaluated using Leicester Cough Questionnaire. Each question is scored on a scale from 1 (maximum impact) to 7 (minimal impact). An average score is calculated for each domain (physical, psychological, and social), resulting in scores ranging from 1 to 7 per domain, and a total score between 3 and 21. A higher score indicates less impact.

Short Form-36 will be applied for assessing quality of life. Higher scores indicate better health status.
