Manage your longitudinal surveys using Waves

What are longitudinal surveys?

Surveys that ask the same or similar questions to the same or similar people at several points in time are longitudinal.

How it works

Stage	How to do it
Step 1: Create a wave for each point in time Common ones are: Baseline Midline Endline	Add one or more Shared Waves to a survey
Step 2: Add those waves to a survey campaign Dictionary A survey campaign is a survey on a project So if you use the same survey on several projects, add the waves to the survey campaign for each project	Add a shared Wave to a survey campaign
Step 3: Customise the survey’s appearance on each wave This is optional if you don’t want to hide or edit certain questions for each wave, you can leave them just as they are	Personalise the Wording of Survey Questions based on the Wave and Respondent Type
Step 4: Select the wave when collecting survey responses You can collect survey responses from Anyone with the public link Coworkers (signed-in-users) Contacts (whom you send a private link) 360° Observers (you send a private link)	Select the wave when collecting longitudinal survey responses
Step 5: Analyse results Pro Tip You can see which Wave a survey response is for to by looking at the label within the post on the Timeline or Newsfeed	View survey results from a specific Wave Longitudinal survey analysis using Waves and Custom Tables Analyse data from Multiple Choice Trackers
