Investigating the feasibility of an 8-week mindful breathing programme on breathlessness and self-efficacy in chronic obstructive pulmonary disease: an open-label study.

backgroundHigh prevalences of anxiety and depression have been found in those with COPD which can exacerbate physically related impacts of increased levels of disability, and reduced enjoyment of life. Of particular concern is the anxiety-breathlessness cycle and reduced self-efficacy, which both adversely affect self-management of symptoms. Recognition of the need to address these issues has led to use of adjunctive psychologically based therapies including mindfulness. Standard mindfulness programmes have been found to be helpful in promoting a less distressing view of breathlessness and increasing self-efficacy in self-management; however, they can be difficult to access due to significant time commitments and need to travel for groups. This study examines a novel, portable, flexible mindfulness intervention for breathlessness that can be self-delivered in the person's home, enabling access to a potentially effective intervention to improve self-efficacy in COPD self-management. The primary aim of this study is to establish the feasibility of delivery of this intervention in terms of uptake and retention in the study, adherence to, and acceptability of the MBI. The secondary aim is to obtain preliminary estimates regarding change in self-efficacy in managing COPD.

methodsThis mixed method pre-post-study with 3-month follow-up will assess feasibility of recruitment, acceptability, and report preliminary descriptive data regarding this novel mindful breathing intervention (MBI) in up to 30 adults with COPD. A secondary outcome measure is change in the COPD self-efficacy scale. Other self-report measures include the St. Georges Chronic Respiratory Disease Questionnaire, Five Facet Mindfulness Questionnaire, Hospital Anxiety and Depression Scale, the EQ-5D-5L, and a daily diary recording breathlessness and mindfulness practice. Descriptive statistics and pre-post-change scores will be reported for quantitative data. A qualitative interview exploring participant experiences of the MBI will be undertaken at the 3-month follow-up point with 10 participants. Qualitative data will be analysed using thematic analysis. Data collection is ongoing at the time of submitting this manuscript. DISCUSSION: This study is the first to assess feasibility of a self-delivered MBI for those with COPD in New Zealand. This study will also establish preliminary estimates of change on self-efficacy and other measures of health outcomes. If feasible, with preliminary evidence of positive impact on functioning, this will support the development of a larger clinical trial. Provision of self-delivered in-home mindfulness-based interventions for people with COPD may not only contribute to improved health, but potentially a reduction in resources, costs, and the time required for travel to group treatments), reducing barriers to treatment for people with COPD.
