Constructing a Mixed Methods Design to Explore the Older Driver—Copilot Relationship

This methodological discussion outlines the process of constructing a mixed methods design using a research project that explored the older driver—copilot relationship and how vehicular technology might influence this relationship, including potential implications on driving safety. The decisions involved with determining a mixed methods design are outlined. A visual model and associated description contextualize the process of determining key design features. Challenges associated with using a hybrid design and strategies used to overcome these challenges are discussed.
