Although CRF predicts other domains of self-efficacy among survivors, the effect of CRF on exercise self-efficacy (ESE)\u2014an important predictor of exercise participation\u2014has not been quantified. This study examined the relationship between CRF, ESE, and exercise participation and explored the lived experience of engaging in exercise among survivors of breast cancer with persistent CRF.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Fifty-eight survivors of breast cancer (3.7 [SD\u2009=\u20092.4] years after primary treatment) self-reported CRF, ESE, and exercise participation (hours of moderate-intensity exercise per week). Regression and mediation analyses were conducted. Survivors who reported clinically significant CRF and weekly exercise were purposively sampled for 1-on-1 interviews (N\u2009=\u200911). Thematic analysis was performed across participants and within higher versus lower ESE subsets.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Greater CRF predicted lower ESE (\u03b2\u2009=\u2009\u22120.32) and less exercise participation (\u03b2\u2009=\u2009\u22120.08). ESE mediated the relationship between CRF and exercise participation (\u03b2\u2009=\u2009\u22120.05, 95% CI\u2009=\u2009\u22120.09 to \u22120.02). Qualitative data showed that survivors of breast cancer with higher ESE perceived exercise as a strategy to manage fatigue, described self-motivation and commitment to exercise, and had multiple sources of support. In contrast, survivors with lower ESE described less initiative to manage fatigue through exercise, greater difficulty staying committed to exercise, and less support.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Survivors of breast cancer with persistent CRF may experience decreased ESE, which negatively influences exercise participation.
