To direct my interviews, I used open-ended qualitative interview questions. I followed the same progression of questions in each interview, and attempted to maintain as much consistency as possible in terms of how the interviews progressed. In many instances, however, I asked spontaneous follow-up questions as appropriate to inquire in more detail into respondents' experiences. At times, respondents would answer questions before I asked them, and as a result the continuity and flow of the interviews sometimes varied. I also used standard probes such as “anything else?,” “tell me more about that” and “can you think of an example of that?” as appropriate. In addition, I sometimes repeated back respondents' comments and made noncommittal response such as “I understand” or “um hmm” to encourage more detailed answers. Accordingly, the following outline describes the skeleton for the qualitative component of these interviews, but does not capture every question that I asked.
