Background: Cancer patients experience multiple symptoms throughout the different stages of their illness, with pain as one of the most frequent. Even though effective treatment options exist, more than 40% of all cancer pain patients do not receive adequate pain management. For pain control, in addition to state of the art treatment by professionals, patients and their family caregivers (FCs) have to use self care strategies on a daily basis, a complex process that profits from targeted support by health care providers (HCPs). In phase 1 of this study, the intervention and the study instruments have been translated, adapted and advanced.
