Feasibility and Acceptability of Collecting Sociodemographic Data in CCTG Trials

This study is being done to answer the following question: Are patients on a clinical trial willing to provide answers to questions about their social, economic, and environmental factors-sometimes called social determinants of health-which affect people's health experiences and access to care. These factors may include income, education, employment, housing, social supports, and experiences with discrimination or stress. Participation will help researchers better understand barriers to participating in clinical trials and access to health care.

Inclusion Criteria: * Adults (≥18 years) who are either: * Currently being screened and consented to a CCTG trial (prospective). * Already enrolled in an ongoing CCTG trial and still under follow-up (retrospective). Exclusion Criteria: * Participants already enrolled or expected to enroll in a CCTG trial that is also collecting the SDoH Questionnaire.
