Ongoing Data Collection
Enrollment Survey
The Enrollment Survey is completed by all twin pairs to enroll in the Washington State Twin Registry. Twins are asked to provide their cotwin’s contact information on the survey. This allows us to invite their cotwin to participate as well. The survey provides researchers with basic health information which they can use to publish papers, apply for grants, and recruit for studies.
Health and Wellbeing
The health and wellbeing questionnaire (HWB) is sent to Registry members every 2-3 years, depending on funding. The HWB is also used in new data collection studies. This questionnaire asks about different behaviors, beliefs, emotions, traits, habits, and health diagnoses.
Data collected from the HWB can be analyzed from a single time point (cross-sectional) or multiple time points (longitudinal).
