This study better understands the views on shared decision-making among Chinese adults who smoke or who have a spouse who smokes. Lung cancer is the second most common cancer among men and women in the United States and is the number one cause of cancer-related mortality among Asians and Pacific Islanders. Clinicians are recommended to initiate conversations about lung cancer screening with eligible patients, provide information about the benefits and harms, and engage in shared decision-making. However, a patient's cultural background can influence decision-making in many ways. Given this, there is a need to understand the perceptions of shared decision-making among different populations (in this case, Asian populations) in order to inform the design of culturally sensitive decision aids for cancer screening. This study evaluates how Chinese populations in the U.S. who currently smoke or who have partners who smoke perceive the process of shared decision-making, their preferences, the perceived barriers and facilitators, and their perspective on currently-available screening tools.
