Participants were eligible if they (1) completed active breast cancer treatments (no time limitation), including surgery or chemotherapy or radiotherapy, although they could still be taking endocrine therapy tablets; (2) had an Australian mobile phone number; and (3) had sufficient English skills to provide informed e-consent. Participants were recruited from April 29, 2020, to February 10, 2021, through (1) paid and unpaid advertisements on social media (eg, Facebook, Instagram, and Twitter); (2) emails from breast cancer organizations (eg, McGrath Foundation, Cancer Council New South Wales, and Breast Cancer Network Australia), including the National Breast Cancer Foundation’s “Register4 Research for Cancer” national online registry of people interested in participating in research; and (3) radio advertisements. Participants could access the study registration website either through a secure weblink or by texting a keyword (wellness) to the study mobile phone number, which would automatically deliver a reply SMS text message containing a secure weblink or by scanning a QR code. The registration website was hosted on the University of Sydney–approved Research Electronic Data Capture (REDCap) application and contained the participant information sheet and e-consent form. Next, participants provided demographic data (ie, sex, age, postcode, ethnic background, and time since completing treatment). To complete enrollment, participants entered their preferred name (nickname) and mobile number into a web-based automated SMS text message delivery software (Burst SMS). The software allowed web-based tracking of SMS text message delivery (eg, successfully or unsuccessfully delivered) and participant replies, and enables researchers to respond to participants, if needed.
