Experimental: Mindfulness Based Stress Reduction
Mindfulness Based Stress Reduction (MBSR) program consists of 8 weekly classes plus an all-day class to train participants in mindfulness and its application, including addressing challenges arising from chronic diseases and life stresses.

Active Comparator: Healthy Living Course (HLC)
The Healthy Living Course (HLC) consists of 8 weekly classes plus an all-day class providing lectures and discussions about health-related topics.
The purpose of the HLC is to match the MBSR for time, attention and group support

Change From Baseline in Asthma Control at 18 Months
Time Frame: Baseline and 18 months
|
Asthma control will be assessed using the Asthma Control Questionnaire (ACQ).
The ACQ is a 7-item validated measure that assesses the 5 asthma symptoms considered most important and most used by clinicians for evaluating asthma control, along with use of short-acting beta-agonist and FEV1 percent predicted.
Patients recall their symptoms and short-acting beta-agonist use during the previous week; FEV1 is obtained from spirometry.
All seven questions are scored on a 7-point scale (0=good control, 6=poor control), and the overall score (range 0-6) is the mean of the seven responses.
Lower scores indicate better outcome.
Minimum = 0, Maximum = 6.
Changes of 0.5 or greater in the score are considered important differences.

Change From Baseline in Asthma-related Quality of Life at 18 Months
Time Frame: Baseline and 18 months
|
Asthma-related quality of life will be assessed using the Asthma-related QoL (AQoL) measure.The AQoL has 30 items assessing impairment in 4 areas of function shown to be important to the QoL of adult patients with asthma (activity limitations, asthma symptoms, emotional function and environmental exposure).
Overall QoL is computed by averaging scores on the 4 domains.
Items assess the degree to which important activities have been limited by asthma during the last 2 weeks on a 7-point scale (1= maximal impairment, 7= no impairment).
Shown to be valid, reliable and sufficiently sensitive to changes in asthma symptoms to capture the effects of an intervention in a clinical trial.
Higher scores = better outcome, minimum score = 30, maximum score 210.
Changes in scores of 0.5 or above represent clinically meaningful improvement in QoL.

Change From Baseline in Respiratory Interoceptive Accuracy at 18-months
Time Frame: Baseline and 18-months
|
Respiratory interoceptive accuracy will be measured using the Breath Perception Discrimination Test (BPDT).
The BPDT measures ability to detect small changes in resistive load.
This test will be done in the Pulmonary Diagnostic Laboratory at each site.
During the test period, the presentation of the resistor will be announced at the onset of a new inspiration for the duration of one full breath cycle.
At the conclusion of the breath cycle, participants pause for 5 normal breaths, at which point the next resistor in the block is presented.
The test will be divided into 6 blocks during which there is a random presentation of each resistor so that participants carry out 30 ratings (6 for each condition) over the course of the test.
Higher score is better outcome, lower score is worse outcome.
Lowest score is zero percent, highest score is 100% Time to complete: 30 minutes.

|
Change From Baseline in Percent Predicted Expiratory Volume at 18-months.
Time Frame: Baseline and 18-months
|
Lung function will be assessed via spirometry.
Spirometry assesses the level of air flow limitation according to the forced expiratory volume in 1 second (FEV1).
The unit of measure is not a score on a scale but rather "percent predicted expiratory volume" to assess air flow limitation.
Measurement will be done in the site Pulmonary Diagnostic Laboratories according to American Thoracic Society guidelines before and after inhalation of bronchodilator.
This includes instructing participants to not take a bronchodilator at least 4 hours prior to their spirometry, and assessing lung function both before, and then 30 minutes after bronchodilator to assess best lung function and responsiveness to bronchodilator therapy.
Higher scores mean better outcome.

Cost Per Change in Quality of Life (QOL)
Time Frame: 18 months
|
This outcome is the Incremental Cost Effectiveness Ratio (ICER).
The ICER estimates how much the MBSR intervention costs, relative to the HLC intervention, to improve the outcome measure by 1 unit.
The ICER is calculated by dividing the incremental cost by the incremental outcome.
The Incremental cost is difference in total costs (sum of program costs and healthcare costs over 18 months, in U.S. dollars) between the MBSR and HLC groups.
The Incremental outcome is the difference between the groups in the chosen measure of health outcome at 18 months (here, mean Asthma-related QoL (AQoL) questionnaire scores).

Cost in Change of Percent Predicted FEV
Time Frame: 18 months
|
This outcome is the Incremental Cost Effectiveness Ratio (ICER).
The ICER estimates how much the MBSR intervention costs, relative to the HL intervention, to improve the outcome measure by 1 unit.
The ICER is calculated by dividing the incremental cost by the incremental outcome.
The incremental cost is the difference in total costs (sum of program costs and healthcare costs over 18 months, in U.S. dollars) between the MBSR and HLC groups.
The incremental outcome is the difference between the groups at 18 months in the chosen measure of health outcome (here, mean Predicted FEV1 scores).
This is not a scale.
