Understanding In-Depth Interviews: A Comprehensive Guide To Qualitative Research

Have you ever had a conversation so deep that it left you thinking for days?

That's the power of an in-depth interview. Whether you're trying to understand why someone chooses one product over another or delving into the emotions behind their decisions, an in-depth interview (IDI) lets you connect with the person on a meaningful level.

By asking open-ended questions and creating space for participants to share their stories, IDIs give you a glimpse into their inner world—their thoughts, emotions, and motivations. In this article, we'll walk through the essentials of in-depth interviews—from how to ask the right questions to using the right tools—showing you why this approach is so valuable in truly understanding the "why" behind people's choices in UX research.

Overview of in-depth interviews

In-depth interviews are a qualitative research method used to gather rich insights through one-on-one user interviews. Unlike structured surveys, In-depth interviews offer a more flexible and open-ended approach, allowing participants to freely share their thoughts, behaviors, and experiences. This method helps researchers gain a deeper understanding of the "why" behind individual choices and actions.
