Knowledge and Attitudes Regarding Healthy Lifestyle and Health Behavior Change in Cancer Patients and Their Partners; A Pilot Study

The investigators will perform a pilot study to gain insight into attitudes, barriers and facilitators for health behavior change in cancer patients and their partners. Results of this pilot will be used to design suitable questionnaires to investigate health behavior change in a larger cohort of patients and their partners. It will also direct future interventions to adequately target patients and, potentially, their partners to improve their lifestyle following a cancer diagnosis.
