A guide for designing and conducting in-depth interviews for evaluation input

This short guide defines in-depth interviews, explains their advantages and disadvantages and the steps involved in their application. 


"In-depth interviews are useful when you want detailed information about a person’s thoughts and behaviors or want to explore new issues in depth. Interviews are often used to provide context to other data (such as outcome data), offering a more complete picture of what happened in the program and why." (Boyce & Neale 2006 p3)
