Asthma and Mindfulness-Based Stress Reduction (MBSR)

Study Overview
=================
Brief Summary
-----------------
Asthma is one of the four most common chronic disorders in adults, affecting 14 million adults in the United States and costing an estimated 7.9 billion dollars in medical care and 5.3 billion dollars in lost work or school. About 40% of asthmatics report using some form of complementary and alternative medicine approach to help reduce their asthma symptoms, but there is little evidence for their effectiveness. Mindfulness-based stress reduction (MBSR) is a group based program shown to reduce medical symptoms and improve quality of life for patients with many different chronic diseases. The goals of the proposed randomized controlled trial are to collect preliminary data on the effect of MBSR on quality of life, symptoms, and lung function in mild and moderate-severity asthmatics and to refine recruitment and data collection procedures for a future, larger clinical trial.

Detailed Description
-----------------
Asthma is a chronic respiratory disease that affects 7% or 14 million adults in the United States. It is one of the four most common chronic disorders in adults, costing an estimated 7.9 billion dollars in medical care and 5.3 billion dollars in lost work or school. Approximately 40% of asthmatics report using some form of complementary and alternative medicine (CAM) approach to help alleviate their asthma symptoms, but there is little evidence for their effectiveness. Breathing and relaxation techniques, including yoga appear most promising. Mindfulness-based stress reduction (MBSR) is a group-based program developed at the University of Massachusetts Medical School (UMMS) that focuses on the cultivation of mindfulness through formal meditation practices and the integration of mindfulness into everyday life as a coping resource to deal with physical symptoms, chronic medical conditions, and difficult emotional situations. MBSR has been shown to be an effective adjunctive intervention in reducing medical symptoms for a broad range of stress-related disorders and chronic diseases, reducing psychological distress anxiety and depression, and improving quality of life. A small preliminary study conducted by our research team found improvements in measures of quality of life, locus of control, stress, and anxiety immediately following the completion of the MBSR program. The overall goal of the proposed two year exploratory study is to conduct a randomized controlled trial (RCT) to test and optimize recruitment and data collection procedures and to collect preliminary data on the effect of MBSR on behavioral and psychological aspects of asthma and lung function to support justification for a larger clinical trial should the results of this study be promising. Eighty-two adults ages 21 and older with a physician-documented diagnosis of asthma classified as either mild or moderate documented will be recruited for seventy participants at final follow-up. Participants will be randomly assigned to one of two conditions stratified by asthma severity: (1) MBSR, or (2) Healthy Living Course (HLC) attention control condition. Participant assessments will occur at study entry (baseline) and at 10-week, 6- and 12-month follow-up. The primary aim of the project is to evaluate the efficacy of the MBSR program in improving quality of life and lung function as assessed by change from baseline to two-week average morning peak expiratory flow (PEF) compared to HLC participants. Secondary aims are to evaluate the effect of the MBSR program on reducing asthma rescue medication use, frequency of asthma exacerbations (prednisone therapy), asthma symptoms, healthcare utilization, number of days of work or school missed, peak expiratory flow (PEF) variation, and psychological distress, and in improving asthma control, asthma-related internal locus of control, and lung function as assessed by spirometry (FEV1).
