This page contains study tools for all completed EHS-Net food research multisite studies. To increase transparency and aid future research that is consistent with the types of questions and data EHS-Net has been collecting, we are posting these files from our completed work.
Study tools are documents that describe in detail how the study was conducted. They can include the following:
- Study protocols, which describe the goals of the study and how it will be conducted or was conducted.
- Data collection instruments, which are the documents used to collect data for the study. These can include interview and observation forms.
- Data collection instructions, which describe in detail how to use the data collection instruments.
When applicable, these studies were reviewed before initiation by the Centers for Disease Control and Prevention’s Institutional Review Board at its Human Research Protection Office and the Office of Management and Budget for Paperwork Reduction Act compliance.
We strongly encourage you to read the publications based on these studies before reviewing these study tools or using them to develop your own studies.
The tools contain a combination of study protocols, data collection instruments, and data collection instructions; however, all three items may not be included in every study.
