Brief summary

Most patients with chronic lung disease underestimate their actual walking ability due to low confidence. To better understand the relationships between lung function, self-efficacy for walking (confidence in ability to walk a defined distance), actual walking ability for the same distance gait speed and physical activity level-PAL- (total energy expenditure/resting metabolic rate). Quality of life, self efficacy for activity questionnaires, physical activity level measurement, 4-meter gait speed and 6-minute walk distance will be measured.

Design outcomes

Primary

Measure	Time frame	Description
Analyze associations between self-efficacy for walking, gait speed, physical activity level and perceptions of symptoms in patient with chronic lung disease (COPD and Pulmonary Fibrosis)	Day of enrollment.	Correlation , regression models and mediation analysis (self efficacy and physical activity) will be performed.

Secondary

Measure	Time frame	Description
Predictive utility of 4-meter gait speed for estimating physical activity level (PAL) as validated by gold standard activity monitor.	1 week	Measure 4-meter gait speed during standardized 6 mintute walk test and compare to armband activity monitor results to determine predictive ability, if any, on PAL in people with chronic lung disease.
