Together-Breast Cancer Support Platform

This study evaluates the acceptability and engagement of a culturally tailored online peer-support program for Korean speaking breast cancer patients and survivors, as well as its potential impact on psychosocial outcomes.

A total of 24 participants will be enrolled, including 8 mentors (breast cancer survivors diagnosed at least two years prior who have completed active treatment or are on long-term maintenance therapy) and 16 mentees (patients currently undergoing treatment).

Participants will be recruited through community outreach using study flyers with a QR code that links to an online eligibility screener. Individuals who complete the screener will be contacted by the study coordinator to confirm eligibility and complete the informed consent process prior to enrollment.

Mentors and mentees will be matched based on information collected from the screener, including demographic and clinical characteristics such as age group and cancer stage at diagnosis. Each mentor may be matched with up to two mentees.

Mentors will complete a structured training program prior to participation. All participants will engage in peer-support interactions through an online platform over a 12-week period, with a minimum expectation of at least one bidirectional interaction per week.

Data will be collected using REDCap. Participants will complete surveys at baseline, mid-intervention (weeks 4-5), and post-intervention (weeks 12-13), with an optional follow-up survey at 6 months.

Outcome measures include engagement metrics, quality of life, psychological well-being (including anxiety and depression), and perceived social support.
