The goal of this study is to evaluate the acceptability and engagement of a culturally tailored online peer-support program for Korean speaking breast cancer patients and survivors. The main questions it aims to answer are: 1) Is the peer-support program acceptable and sustainable in terms of engagement between mentors and mentees over a 12-week period? 2) Does participation in the program improve quality of life, psychological well-being (including anxiety and depression), and perceived social support?

Participants will include Korean speaking breast cancer survivors (mentors) and patients currently undergoing treatment (mentees). After enrollment and matching based on screening information, participants will engage in peer-support interactions through an online platform for 12 weeks. Surveys will be administered at baseline, mid-point, post-intervention, and optional 6-month follow-up to assess outcomes.

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.

The study population consists of Korean American breast cancer patients and survivors. Participants include mentors (breast cancer survivors diagnosed at least two years prior and who have completed treatment or are on long-term maintenance therapy) and mentees (patients currently undergoing active breast cancer treatment). All participants are required to have access to a smartphone or computer and be able to participate in an online peer-support platform. Participants will be recruited through community outreach, referrals, and self-referral using a QR code-based screening process.

No, individual participant data will not be made available to other researchers.
