BACKGROUND For women diagnosed with hormone-receptor-positive breast cancer, endocrine therapy (ET) is recommended. Patients experience diverse side effects, and difficulties in managing these side effects have been identified as obstacles for treatment continuation. The aim of this study was to describe the development of a support program for patients prescribed ET. METHODS Intervention mapping (IM) a comprehensive theory-based approach was used in the support program development. A participatory design was used and four advisory groups was formed including both patients and healthcare professionals. RESULTS This study employed the systematic stages of IM to develop a theory-based support program with the goal to empower patients prescribed ET to manage ETrelated symptoms and problems, and to illuminate the healthcare structure. The needs assessment identified three performance objectives: (1) Patients have knowledge of and understand their symptoms and their management strategies. (2) Patients have the knowledge and confidence to express their care needs and to ask for guidance from healthcare professionals. (3) Patients are active in and lead their healthcare process. CONCLUSION This is a systematic developed model, built upon aspects of ET both from a patient´ perspective as well as from healthcare professionals' perspectives.
