Qualitative interviews will be conducted by phone by a trained qualitative research interviewer. Interviews will be in-depth and semistructured, utilizing a combination of broad, open-ended questions and more specific probes. The interview guide was developed with the help of Dr. Michael Fisher, PhD, who has expertise in qualitative research methodology. The interviewer will take detailed field notes. This portion of the interview will last approximately 25-35 minutes and will be digitally recorded and professionally transcribed. After each interview, the interviewer will complete an Interview Summary Form, which will serve as a memoing tool and summarize initial themes or impressions that may be relevant to the research question.
