The semi-structured interviews will serve an as efficient investigation technique for assembling large amounts of data in a relatively short time frame that offers insight into a broad range of issues on a particular topic. A semi-structured interview guide (Appendix A) outlining the information that will be inquired about during the interview was developed for the purpose of this study. Semi-structured interviews entail asking each interviewee a specific set of predetermined questions in the same and consistent manner. However, they also allow flexibility for the interviewer to alter the order of the questions and probe the participants further to gain more information. These probes (or prompts) are questions not found in the interview guide that will be used to encourage elaboration of responses and further discussion to particular questions. These will be posed to the interviewees in a neutral and unbiased manner. Furthermore, additional questions may be added to subsequent interviews if deemed to be useful at extracting previously unanticipated and potentially useful information. Due to the qualitative nature of the study, the total number of participants is estimated to be between 10 and 15, and will depend on when saturation is achieved. Saturation occurs when no new information or emerging themes are uncovered with subsequent interviews. The interviews will be conducted by a medical student who is a co-investigator for the project and has undergone interview training from experienced researchers and are anticipated to last approximately one hour. During the interview, key points arising will be manually documented by the medical student. The completed interview will also be digitally audiotaped and transcribed verbatim, and the digital files, interview transcripts and field notes will be uploaded to a qualitative software package, NVivo 8.
