The Health & Wellbeing Questionnaire is an ongoing at-home study of the Twin Registry. It is a type of study called a “longitudinal research project,” which involves studying the same group of individuals over an extended period of time. The goals of this study are to understand how genetic and environmental factors influence human health, disease and behavior, and to see how your health changes over time.

In 2009, we were awarded a large infrastructure grant. One of the projects for this grant was to expand the size of our survey data repository. The Health & Wellbeing Questionnaire was developed from our previous surveys to collect data about health issues, habits, thoughts and beliefs. Data collection began in 2010, when we mailed the first Health & Wellbeing questionnaire to members of the UW Twin Registry.

In 2013, we started emailing invitations to members of the Twin Registry to complete the Health & Wellbeing questionnaire online. For many twins, this will be a follow-up to a questionnaire they completed at some time in the past few years. For others, it may be the first questionnaire they fill out, which will establish a baseline time-point for data collection in the future.
