What Is a Longitudinal Study?

At a Glance

Longitudinal studies collect data on multiple occasions from the same participants over a defined period of time.

 

Longitudinal studies can provide valuable insight into how participants behave and interact with their surroundings, an experience, or a brand over time in their everyday lives.

Longitudinal studies can be conducted at any time during the lifecycle of a product. However, they are typically done when collecting feedback on a live product or service:

  • Before development, as a way to gather requirements and understand users
  • After a site or product has been launched, to gather data on how, when, and why people naturally use it
