Breast Cancer

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.

Inclusion criteria

* Within 5 years of completing primary cancer treatment (surgery, chemotherapy, and radiation) for Stage 0-III breast cancer. * Own an Android or iPhone smartphone and willing to use the smartphone to complete app-based surveys during the assessment period. * Willing to wear the ActiGraph monitor during the assessment period. * Willing to wear the study issued Fitbit Versa 3 smartwatch during the assessment period. * Access to internet to complete REDCap survey assessments.

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
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 periodThe 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

MeasureTime frameDescription
Proportion of the sample with valid accelerometer data at the end of the 10-day data collection period.10 day data collection periodThe number of participants with valid accelerometer data out of the total number of participants in the sample during the 10-day data collection period.
Rate of phone-based ecological momentary assessment (EMA) prompt completion.10 day data collection periodThe 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.
Rate of electronic daily dairy completion.10 day data collection periodThe 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.
