The Roles of Peers and Functional Tasks in Enhancing Exercise Training for Adults With COPD

Participant goal participation will be measured by improvement in initial goals set at the beginning of the study using the Canadian Occupation Performance Measures (COPM). Success will be determined by calculating individuals change score on their satisfaction with their performance in their target areas post-intervention. A change score of 2 on an item is said to represent significant change (Law et al., 2000). A change score of at least 2 on 50% of items (dependent on personal goals) for 70% of participants will be the indicator of success.

This test measures the time it takes an individual to stand from a standard chair (approximately 46cm), walk 3 metres, walk back, and return to sit on the chair (Podsiadlo & Richardson, 1991). The participant is timed from when the leave the seat to when they are seated again. A time of >30 seconds is the cut-off for safe unsupervised participation (Podsiadlo & Richardson, 1991). Anyone who gets a time >30seconds will be informed that they cannot participate.

The 1-minute sit-to-stand test is a measure of exercise capacity that has been validated with individuals living with COPD (Puhan et al., 2013). Individuals sit on a standard chair without arm rests, with their legs hip-width apart and about 90 degrees knee flexion and aligned and are asked to hold their hands stationary on their hips. Participants are then asked to stand and sit 1-2 times to familiar themselves with the movement. Then, for the duration of 1 minute, participants are asked to do as many repetitions as possible of the sit to stand, without using arms for support. The number of repetitions is recorded.

To measure handgrip strength, we will use a Hand Dynamometer that will be sent to participants. Individuals sit with their shoulders adducted, elbows flexed to 90˚ and forearms in a neutral position (Puhan et al., 2013). They are then asked to squeeze the handle as much as possible and read to the nearest kilogram where the needle stopped, which is then recorded. The best of six measurements is used as an indication of upper body strength.

On a scale from 0-10, participants' indicate their breathlessness level. 0- No breathlessness at all to 10- Maximal breathlessness

Self-reported physical activity levels measured in length of bouts over the previous 7 days to determine physical activity frequency.

This 1-6 scale represents different feelings people have when they exercise. 1-true to how they typically feel when exercising, and 6-false to how they typically feel when exercising.

This 7 point scale relates to the reasons why one would either start to exercise regularly or continue to do so. 1- not at all true to the reason why they would exercise regularly, and 7- Very to true to the reason why they would exercise regularly.

This 4 point scale measures how often during the past 4 weeks peers (i.e. other people with COPD) have provided informational and emotional support to the participant. 1- Never provided the support described and 4- Very often provided the support described.

This questionnaire was used to measure participants' breathlessness burden using a single item scale from 0 to 4, where a score of 0-1 indicated mild breathlessness and 2-4 indicated increased breathlessness.

This questionnaire was used to measure the impact COPD is having on well being and daily life. The CAT is an eight-item semantic differential scale from 0 to 5, where 0 is no impact and 5 is extremely impactful. Participants' scores were totaled and a score of ≥ 10 indicated higher than normal burden of disease.

Participants will answer 26 questions based on daily and social activities and be asked if they participate in said activity. Responses include: Yes - as much as I want. Yes - but less than I want. No - but I would like to do it. No - and I don't want to do it.

This 7 point scale measures feelings about being a part of the exercise and peer support group. 1-strongly disagree and 7- strongly agree to indicate agreement with each of the statements.

The Acceptability of Intervention Measure will be administered to measure high acceptability and satisfaction with the intervention. Using a 5 point scale, participants will answer 8 questions and rate them as 1- Completely disagree to 5- Completely agree.

The Intervention Appropriateness Measure will be administered to measure high acceptability and satisfaction with the intervention. Using a 5 point scale, participants will answer 8 questions and rate them as 1- Completely disagree to 5- Completely agree.

The Feasibility of Intervention Measure will be administered to measure high acceptability and satisfaction with the intervention. Using a 5 point scale, participants will answer 8 questions and rate them as 1- Completely disagree to 5- Completely agree.

This 7 point scale measures how strongly the participant experienced interest, intrigue, focus, enjoyment, and annoyance during their participation in he Functional Tasks and Peer Support Intervention. 1-not at all experienced during the intervention to 7-extremely experienced during the intervention.

Participants completed a questionnaire that asked them to rate on a scale from 1 (not once) to 5 (daily) how frequently they have used goal setting, action planning, coping planning, physical restructuring, self monitoring, values identification, social restructuring, resource finding, and self belief in the past two weeks,
