Self-efficacy Coaching for Women With Breast Cancer

This is an open, prospective, multi-center, interventional study to evaluate the benefit and efficacy of individualized self-efficacy coaching for women with high-risk early breast cancer. In total, 6 sites will be assigned 1:1 to either the experimental arm (Group A) or the control arm (Group B). The controlled site assignment will assure a balanced site-specific QoL between both groups at baseline. All patients will be medically treated according to guidelines. The experimental Group A will in addition receive regular self-efficacy coaching.
