An Observational Pilot Study to Test a Smartwatch-based EMA Method During Exercise With Breast Cancer Survivors

Completed

• Conditions: Breast Cancer

• Registration Number: NCT05868746
• Lead Sponsor: Dartmouth-Hitchcock Medical Center

Brief Summary

The goal of this pilot study is to evaluate the feasibility and acceptability of collecting ecological momentary assessment data regarding feeling states during physical activity among a cohort of breast cancer survivors, using a novel smartwatch app created by the study team called "PHITbit."

Primary Outcome Measures

Name	Time	Method
Feasibility of using a smartwatch-based ecological momentary assessment (EMA) method during exercise measured as the proportion of participants who use the data collection app and provided at least 3 responses to EMAs during a single exercise session.	10 day data collection period	The number of participants who use the smartwatch data collection app and respond to at least 3 EMAs during a single exercise session at least once during the 10-day data collection period out of the total number of participants enrolled at the end of the10-day data collection period.
Acceptability of collecting during-exercise feeling state data using a smartwatch-based ecological momentary assessment method measured using the System Usability Scale.	End of study follow-up (post 10-day data collection period)	The System Usability Scale (SUS) is a 10-item self-report scale used to measure perceived usability of a system, method, or tool. Responses on the SUS range from 1 = strongly disagree to 5 = strongly agree. Higher scores indicate greater acceptability.
Acceptability of collecting during-exercise feeling state data using a smartwatch-based ecological momentary assessment method measured via a semi-structured interview.	End of study follow-up (post 10-day data collection period)	Semi-structured interview to assess participants' perceptions regarding their experience using the smartwatch-based ecological momentary assessment method.

Secondary Outcome Measures

Name	Time	Method
Rate of electronic daily dairy completion.	10 day data collection period	The number of electronic daily dairies completed by participants during the 10-day data collection period out of the total number of electronic daily dairies delivered to participants.
Rate of phone-based ecological momentary assessment (EMA) prompt completion.	10 day data collection period	The number of phone-based EMA survey prompts completed by participants during the 10-day data collection period out of the total number of phone-based EMA survey prompts delivered to participants.
Proportion of the sample with valid accelerometer data at the end of the 10-day data collection period.	10 day data collection period	The number of participants with valid accelerometer data out of the total number of participants in the sample during the 10-day data collection period.
