Physical activity (PA) interventions can improve QOL, but many rely on costly specialists or are difficult to scale. We adapted an evidence-based peer-mentoring program (moving forward together) for web delivery (webMFT). The platform centralizes peer-coach matching, delivery, and coordination to reduce administrative burden and improve scalability.<\/jats:p>\n <\/jats:sec>\n \n Purpose<\/jats:title>\n We evaluated webMFT\u2019s cost-effectiveness.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n In a 12-week randomized trial (N\u2009=\u200961), survivors were assigned to webMFT (n\u2009=\u200930; weekly phone calls plus activity self-monitoring) or MVPA Tracking (n\u2009=\u200931; activity self-monitoring only). From a payer\u2019s perspective, we estimated incremental cost-effectiveness ratios (ICERs) for quality-adjusted life years (QALYs) and device-measured moderate-to-vigorous physical activity (MVPA). Intervention costs were collected from time logs for research staff and peer coaches. We conducted sensitivity analyses by bootstrapping and constructing cost-effectiveness planes and cost-effectiveness acceptability curves (CEACs).<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n In the base-case analysis the ICER for webMFT was $38\u2009430 per QALY gained versus MVPA Tracking. At the high end of probabilistic implementation-cost sensitivity analyses that considered wider ranges of wages, platform costs, and implementation times, the mean ICER was $43\u2009418 per QALY and the probability of cost-effectiveness was 87% at the commonly used $150\u2009000 per QALY threshold. WebMFT increased QALYs but did not produce greater increases in device-measured PA compared with MVPA Tracking.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n At a $150\u2009000 per QALY threshold, webMFT appears cost-effective for improving QALYs among breast cancer survivors. Larger studies are needed to confirm these findings.<\/jats:p>\n <\/jats:sec>\n \n Clinical Trial Information<\/jats:title>\n This underlying clinical trial was registered at clinicaltrials.gov
