Enjoyment of Physical Activity in young adult cancer survivors
Enjoyment of Physical Activity will be measured at baseline, 24 and 48 weeks using the Physical Activity Enjoyment Scale.
This 18-item scale assesses enjoyment for physical activity by asking participants to rate "how you feel at the moment about the physical activity you have been doing" using a 7 point bipolar Likert scale, from 1 (I enjoy it) to 7 (I hate it). Eleven items are negatively worded and seven items are positively worded. After reverse scoring the 11 negatively worded items, an overall enjoyment for physical activity score is determined by summing the items, with a value range of 18-126 being possible. Higher scores indicate higher enjoyment, better outcome.
Leisure Time Physical Activity in breast cancer survivors
Leisure time physical activity will be measured at baseline, 24 and 48 weeks using the Godin Leisure Time Exercise Questionnaire Physical Activity.
This is a measure of self-reported physical activity participation. Participants report "times per week" they participate in strenuous (e.g., jogging), moderate (e.g., fast walking), and mild (e.g., easy walking) exercise over the past 7 days and the "average duration each time you exercised (in minutes)" for each of the three activity categories. Weekly minutes of total, light, moderate, and vigorous activity are calculated by multiplying the frequency and time of each activity. This value is divided by 7 to obtain daily averages. The minimum value one can score is 0, and the maximum depends on the number of self-reported minutes of physical activity. Higher scores indicate better outcome.

Confidence in ability to be regularly active will be measured at baseline, 24 and 48 weeks using the Exercise Self-Efficacy (EXSE).
This short form assesses the participants' beliefs in their ability to be regularly active "for the next 12 weeks" on a scale from 0% (not at all confident) to 100% (completely confident), with higher scores representing better outcome.
Confidence in ability to be regularly active despite common barriers in breast cancer survivors
Confidence in ability to be regularly active despite common barriers will be measured at baseline, 24 and 48 weeks using the Barries Self-Efficacy (BARSE).
This scale assesses the beliefs in ability to be regularly active despite common barriers "for the next 12 weeks" on a scale from 0% (not at all confident) to 100% (completely confident), with higher scores representing better outcome.

Exercise goal setting in breast cancer survivors will be measured at baseline, 24 and 48 weeks using the Exercise Goal Setting Scale.
This scale assesses exercise goal setting behaviors on a scale from 1 (does not describe) to 5 (describes completely), with higher scores representing better outcome.
Sitting time in breast cancer survivors
Sitting time in breast cancer survivors will be assessed at baseline, 24 and 48 weeks using the Sitting Time Questionnaire.
This questionnaire assesses the amount of hours and minutes spent sitting during weekdays and weekends, with lower scores representing better outcome.
Outcome expectations for exercise in breast cancer survivors
Outcome expectations for exercise in breast cancer survivors will be assessed at baseline, 24 and 48 weeks using the Outcome Expectations for Exercise_MOEES.
This scale assesses the beliefs and expectations about the benefits of regular exercise and physical activity on a scale from 1 (strongly disagree) to 5 (strongly agree), with higher scores representing better outcome.
Mindful Awareness in breast cancer survivors
Mindful awareness of distressing thoughts and images will be measured at baseline, 24 and 48 weeks using the Southampton Mindfulness Questionnaire (SMQ).
This 16-item scale measures mindful awareness during distressing thoughts and images. Using a 7-point Likert scale (0=strongly disagree to 6=strongly agree), items reflect the following subscales: mindful observation (4 items), letting go (4 items), non- aversion (4 items), and non-judgment (4 items). The minimum value one can score on any of the subscales is 0, and the maximum is 24. The minimum value of the total measure is 0, and the maximum is 96. The higher scores represent better outcome.
Mindful self-compassion in breast cancer survivors
Mindful self-compassion will be measured at baseline, 24 and 48 weeks using the Self-Compassion Short Form.
This short form is a 12-item scale measuring items related to self-kindness, self-judgment, and common humanity. Statements on the Self-Compassion Scale are scored on a Likert scale of 1 (almost never) to 5(almost always). To calculate an overall compassion score - Items representing uncompassionate responses to inadequacy or suffering (the self-judgment, isolation, and over-identification subscales) are reverse-coded only when calculating the overall compassion score. In this way, higher scores represent a lower frequency of these responses.
Post-traumatic growth in breast cancer survivors
Post-traumatic growth will be measured at baseline, 24 and 48 weeks using the Post-traumatic Growth Inventory.
This 21-item self-report scale assesses growth or benefits after a specific traumatic life event. The Post Traumatic Growth Inventory (PTGI) is scored by adding all the responses, with higher scores representing better outcome.
Implementation feasibility measured by enrollment rate
This indicator of implementation feasibility for the interventions delivered is defined by the overall enrollment rate being >/= 70% (e.g., total number of individuals enrolled/total number approached). Enrollment rate will be tracked continuously during the 48 week study.
Implementation feasibility measured by retention rate
This indicator of implementation feasibility for the interventions delivered is defined by the retention rate being >/= 70% (e.g., total number of participants who drop out/ total number randomized). Retention rate will be tracked continuously during the 48 weeks of the study and significant differences between the study interventions in the number of participant withdrawals will be tracked.
Adherence to the study app + Fitbit by breast cancer survivors
Adherence to the study app + Fitbit will be monitored and usage tracked continuously during the 48 week study.
Objective data include Fitbit wear time, number of times app is opened each week, time spent in app each time it is opened, and for participants who receive each component, usage of general and moderate to vigorous intensity physical activity specific mindfulness videos (i.e. whether clicked, how many times and for how long), number of e-coaching exchanges, number of buddy training webinars attended, and number of buddy interactions in the app.
Acceptability of the technology supported physical activity interventions as measured by a post-intervention evaluation survey
Acceptability will be measured using a brief, Likert-type survey assessing participant enjoyment, satisfaction, perceived benefit, and ease of use. Acceptability is defined as >/= 70% of survey responses in affirmation of this.
