Study Design Semi-structured interviews will be conducted with key informants, defined as individuals who have good knowledge and understanding about the disease of their family member or friend with inflammatory arthritis and can clearly articulate their knowledge. These interviews serve as an investigative technique for gathering data in short period of time and to gain new insight and a broad perspective of views on the research question. Although the same specific questions will be asked in the same manner with each interview, the interviewer will be free to alter the order in which questions are asked so that the interview caters towards each individual research participant. An interview guide (Appendix A) was developed for the purpose of this study, and an interview notes form (Appendix B) will be used for interviews. As it is a semi-structured interview approach, certain probe questions that aim to encourage research participants to elaborate on their responses and further discussion have not been included in this guide. Such probe questions are context-dependent and evolve as the interview takes place.
