In Depth Interviews

One-on-one conversations that reveal profound insights

What Are In-Depth Interviews?

In-Depth Interviews (IDIs) are one-on-one qualitative research sessions where a trained interviewer engages with a single participant in a comprehensive, exploratory conversation. These interviews typically last 30-90 minutes and provide a private, comfortable environment for detailed discussion.

Unlike surveys or focus groups, IDIs allow for deep exploration of individual perspectives, personal experiences, and complex decision-making processes without the influence of group dynamics.

The intimate, personalized nature of IDIs encourages participants to share honest, detailed responses and allows interviewers to probe deeply into topics, adapt questions in real-time, and uncover insights that might not emerge in group settings.

Key Advantages

  • Deep, personalized understanding of individual perspectives
  • No group influence on participant responses
  • Flexible to explore sensitive or complex topics
  • Ability to adapt questions based on responses
  • Scheduling flexibility for hard-to-reach participants
  • Rich, detailed data from each conversation
