Understanding patients' preferences for decisional roles is important in providing quality cancer care and ensuring patient satisfaction. The knowledge about processes and contents of decision making and improving communication between patients, family, and health care providers is lacking, especially in palliative care settings. In prior studies, our team found that physicians could not consistently predict patients' decision making preferences. We hypothesize that there will be overall regional differences in decisional control preference, with a lower overall percentage of passive decision control in developed countries compared to developing countries. Objectives: Primary: To describe the proportions of passive decision making for individual countries throughout the world. Secondary: To compare the proportion of passive decision making in developed and developing countries; To determine: the agreement between patients' decisional control preferences and their self-reported actual decision-making experiences regarding cancer care; patients' level of understanding of their illness and prognosis.
