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 infiuence 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. (Author/publisher)
