Two second-year medical student co-investigators and/or the study coordinator from the University of Toronto will be present at each focus group session. A semi-structured interview guide will be used (Appendix 3 - Interview Guide) with probes to prompt further discussion when appropriate. One medical student will conduct the focus group while the second student or study coordinator will keep a speaker log and take notes throughout the session. Each participant will be assigned a number and a record will be kept of the first phrase of each speaker. The speaker log will be used to aid in the analysis (i.e. to clarify if the view was expressed by a number of people or one person many times). During focus group discussions, only the first name of each participant will be used.
