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.

It is anticipated that 1000 people will take part in this study. Participation in this study will only take about 10 minutes or less. Participants who choose to take part in this study will be asked to fill out a form with questions in English or French about the non-medical factors that influence health. This includes asking about the conditions and places in which the participant lives, learns, works, and plays. Participants will also be asked how they feel about answering these questions. Researchers will use this information to better understand who participates in clinical trials.

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.

This study is designed to include participants who have consented to a CCTG clinical trial. If a patient consents to a CCTG trial but does not enroll, they will remain eligible for SC.32S.
