A study of LIFE exposures.

About

What is the Early Life Exposures Assessment Tool (ELEAT)?

ELEAT explained

The ELEAT is a questionnaire created to assess the role of environmental exposures during early life windows of susceptibility relevant to autism and other developmental concerns. The ELEAT Team has tested many of our questions to ensure that they measure risks as accurately as possible and can be understood by wide audiences.

Research purposes

We are sharing the ELEAT with scientists who study autism and developmental delays from a variety of perspectives around the globe. Gathering information about early life environmental risk factors may impact how our partner scientists think about brain development while at the same time providing critical information to support our research.

Long-term goals

Widespread use of a single standardized tool to examine early life exposures will facilitate cross-study analyses, increasing the scientific impact of individual studies and allowing us to explore uncommon risks in large and diverse populations. Our end goal is to use this knowledge to develop strategies to prevent autism and optimize brain development in our children.

Parents

Your participation means so much.

By taking part in this survey, you will become part of a large effort to unravel the root causes of autism and developmental disabilities. Before you begin, please read the steps to get started (below) so you will be prepared for the types of knowledge and documents we will need for this research. Once you click on the link to the questionnaire, you will be redirected from this site to a secure site. Your information will remain secure and private.

Step 1

If you can, please take some time to gather as much information as you can about the period of time beginning 3 months prior to conception through pregnancy, labor and delivery and infancy through your child’s first birthday. This may include:

  • Calendars
  • Diet and nutritional supplements used during that time period
  • Addresses and household information
  • Medications used during that time period

Step 2

Once you have all your information, please take our survey by clicking the "Take Survey" button below. You will be directed away from this site to a secure site to complete the survey. Enter the username and temporary password provided to you by your site coordinator. You will be asked to review a consent form and consent to participate. You will be asked to create a new password and provide your email address, in case you forget your password. Once you have registered, you will be taken to the survey to begin. You may save and return as many times as you need in order to finish the questionnaire. Thank you!

ELEAT Contents

ELEAT is a self-administered questionnaire designed for parents (usually mothers) to answer about their child. It includes ~ 260 questions organized into 10 different modules including a module asking about the questionnaire itself. Many questions are skipped depending on gateway question responses. Modules X and B are always asked first, and Module I is always asked last. The rest of the modules are presented in a random order for the online survey. Average completion time is about an hour, but ranges from a half hour to an hour and a half.
