Frequently Asked Questions
What is an in-depth interview (IDI)?
An in-depth interview (IDI) is a one-on-one qualitative research method lasting 30-90 minutes. A trained interviewer explores a respondent's thoughts, feelings, and behaviors in detail. IDIs are ideal for sensitive topics, complex decisions, or executive/B2B research in Caribbean and LATAM markets.
When should you use IDIs vs focus groups?
Use IDIs for sensitive topics, B2B/executive research, complex individual journeys, or when group dynamics might bias responses. Use focus groups when you want group interaction, idea generation, or need to observe social dynamics. IDIs provide depth, focus groups provide breadth.
How many in-depth interviews are needed?
Typically 15-30 IDIs are sufficient to reach thematic saturation for most research objectives. B2B studies often require 10-20 interviews, while consumer studies may need 20-40. The number depends on audience diversity and research complexity.
What are executive in-depth interviews?
Executive IDIs are specialized interviews with senior business leaders, decision-makers, or industry experts. They require experienced interviewers who can engage at a strategic level, use appropriate business language, and probe complex topics. HRG conducts executive interviews across Caribbean and LATAM industries.
