• Number of steps on the ActiGraph GT3X+ activity monitor [ Time Frame: Seven days ] [ Designated as safety issue: No ]
  Participants will wear the ActiGraph GT3X+ activity monitor for seven consecutive full days between Visit 1 (Day 0) and Visit 2 (Day 8).
  
  

• Number of steps on the ActivPAL activity monitor [ Time Frame: Seven days ] [ Designated as safety issue: No ]
  A sub-group of participants will wear the ActivPAL (n=20). Participants will wear the ActivPAL activity monitor for seven consecutive full days between Visit 1 (Day 0) and Visit 2 (Day 8).
  
  
• Time spent in physical activity and in sitting using the International Physical Activity Questionnaire [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  Participants will complete the International Physical Activity Questionnaire at Visit 2 (Day 8). It will be used to measure participants' time spent in physical activity in the last seven days and also to provide self-reported sitting time.
  
  
• Number of steps on the Yamax Digiwalker pedometer [ Time Frame: Seven days ] [ Designated as safety issue: No ]
  Participants will wear the Yamax Digiwalker pedometer for seven consecutive full days between Visit 1 (Day 0) and Visit 2 (Day 8).
  
  
• Exercise Capacity using the Modified Shuttle Test [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  Participants will complete the Modified Shuttle Test at Visit 2 (Day 8).
  
  
• Quality of Life using the Quality of Life Questionnaire - Bronchiectasis [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  Participants will complete the Quality of Life Questionnaire - Bronchiectasis questionnaire at Visit 2 (Day 8).
  
  
• Quality of Life using the EuroQOL-5D [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  Participants will complete the EuroQOL-5D at Visit 2 (Day 8).
  
  
• Quality of Life using the Leicester Cough Questionnaire [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  Participants will complete the Leicester Cough Questionnaire at Visit 2 (Day 8).
  
  
• Stage of change in terms of physical activity using the Stages of Change Questionnaire [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  Participants will complete the Stages of Change Questionnaire at Visit 2 (Day 8). The Stages of Change Questionnaire is the temporal part of the transtheoretical model. It will be used to determine the current stage of change the participant is at in terms of their physical activity behaviour.
  
  
• Confidence to undertake physical activity using Marcus's Self-Efficacy Questionnaire [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  Participants will complete Marcus's Self-Efficacy Questionnaire at Visit 2 (Day 8). Marcus's Self-Efficacy Questionnaire is a component of the transtheoretical model which will provide more detailed information on each individual's confidence to undertake physical activity in different situations.
  
  
• Perception of the benefits and negative aspects of physical activity using Marcus's Decisional Balance Questionnaire [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  Participants will complete Marcus's Decisional Balance Questionnaire at Visit 2 (Day 8). Marcus's Decisional Balance Questionnaire is a component of the transtheoretical model which will assess each individual's perceptions of the benefits and negative aspects of physical activity.
  
  
• Strategies used to progress through the different stages of change using Marcus's Processes of Change Questionnaire [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  Participants will complete Marcus's Processes of Change Questionnaire at Visit 2 (Day 8). Marcus's Processes of Change Questionnaire is a component of the transtheoretical model describing the strategies and techniques individuals use to progress through the different stages of change.
  
  
• Perception of the feasibility and acceptability of the physical activity outcome measures. [ Time Frame: Day 8 ] [ Designated as safety issue: No ]
  The researcher and the participants will answer the feasibility and acceptability questions at Visit 2 (Day 8). The feasibility and acceptibility questions were designed specifically for this study to assess the researchers' and patients' perspectives of the feasibility and acceptability of the physical activity outcome measures.
  
  

Bronchiectasis is the presence of abnormal, irreversibly dilated, thick walled bronchi that have not been caused by cystic fibrosis. Promoting physical activity and decreasing inactivity (e.g. sedentary periods of activity such as sitting/lying) has been proposed as a key component of care for chronic disease but there is no research on physical activity in bronchiectasis. There is research describing physical activity in other respiratory populations, however, the disease trajectory and demographic profile of bronchiectasis is sufficiently different to warrant the proposed research specifically in bronchiectasis

The investigators need to explore physical activity in bronchiectasis and also provide specific information on the instruments used to measure physical activity. There are several methods which could be used to assess physical activity including subjective methods (e.g. questionnaires), objective methods (e.g. motion sensors). In this study the investigators are using a range of assessment tools to help determine their usefulness (feasibility and acceptability from the health professional and patient perspective) for quantifying physical activity in bronchiectasis.

This study will also assess patients' readiness to change (stages of change, self efficacy, decisional balance and processes of change). Understanding patients with bronchiectasis readiness to change physical activity behaviour and the links between the other important outcome measures will help to inform a future physical activity intervention specifically in patients with bronchiectasis.
