Qualitative interviews involve flexible, unstructured conversations to understand participants' perspectives. They are commonly used in combination with other methods like observation. Interviews can vary in structure from unstructured to semi-structured using an interview guide. Factors like number of interviews, use of visual aids, group settings, and recording methods are considered. Locating respondents, obtaining consent, and addressing issues like researcher effects are important planning considerations. Analyzing interviews involves transcription and identifying common themes.
